逛日本的几个小tip
首先是简单懂些日语最好了，比如先把吃的记住。这样去深夜厨房那种街拐角的居酒屋啥的找吃的比较容易交流些。旅游景点附近的店子基本上都有会说英语的人或者英文/中文菜单。
Fidelity的Cash Management Debit卡在支持Visa的ATM机上取日元没问题，手续费Fidelity补贴。比如随便找个街拐角7-11的便利店的ATM就行，我有次在三井住友的ATM上反而不行，只收日本卡和银联卡。
CSR卡基本可以到处刷，稍微大点的店和餐馆都收VISA。
移动支付等于零蛋，有也是少数收支付宝的地方。还是有很多地方只收cash，比如不少地方买门票，还有坐地铁，JR的普通车（新干线的自动售票机可以刷卡）。所以还是得备一些现金。我们基本上是一天逛吃逛吃2万日元的样子，有些还是刷卡。主要是吃喝门票，基本上没买什么东西。
住就用airbnb就好。日本人都非常爱干净，也很安全。我们在大阪住了两晚，京都住了三晚，东京住了两晚，都是airbnb。同样的价钱能找到比宾馆大很多的房子。比如我们在东京上野站旁边住的那个，一晚上才70多美元，一个studio大概有40多平米的使用面积，住hotel估计要奔两百去了。
出租车真心很贵，而且也没有很多空车在路上到处跑，打个三四公里之内的短途还行，远了那是要吐血的。不过好在日本的轨道交通实在是太发达了。就算京都这种地铁线少的地方，bus也还很方便。在这里推荐一个台湾人做的日本交通攻略网站，非常好用。我基本上就是靠这个了解和使用日本的公共交通系统的。

唐朝的吃
1. 唐朝著名的烧尾宴里面没有猪肉，烧尾宴采用了鱼、虾、蟹、鸡、鸭、鹅、牛、羊、鹿、熊、兔、鹤，甚至还有青蛙，唯独就是没有猪肉。 上层社会吃猪肉一般是从宋朝以后开始，宋朝的士大夫阶层也不吃猪肉。苏东坡的那句贵人不肯吃，贫人不解煮，反应了当时人们对猪肉的态度。唐宋时代，社会上层吃绵羊肉，底层老百姓吃猪肉，南宋以后，由于丢失了北方出产绵羊的领土，南方的山羊肉又太膻，虽然智慧的南宋人培育出了接近北方绵羊的湖羊，但由于价格实在太贵，无奈之下，民间对于猪肉的需求才开始上涨。
2.菠菜是唐代的时候引进的，原产国是波斯，由尼波罗国(今尼泊尔)传入的，是作为贡品传到唐朝的，刚开始叫波棱菜，后来简称菠菜。我们闽南语至今还保留着菠薐菜的叫法，粤语也是。
3.唐朝最高端的水果是荔枝，算得上是顶级奢侈品了，因为生长的地方离中原实在是太远了，而且这种水果还不容易保存，能吃到真的不容易，所以在唐朝能吃上荔枝是一种身份和地位的象征，连杨贵妃这种人吃个荔枝都那么不容易了，更别说一般人了。在长安的街头吃上一颗荔枝，可以上唐朝的新闻联播了。
4. 樱桃，樱桃在唐朝也是一种高级的水果，唐朝的新科及第的进士们会吃“樱桃宴”，就是樱桃蘸着奶酪吃，是当时比较流行的吃法~
5. 唐朝人吃梨，不是洗干净就吃，是蒸着吃，这是当时整个唐朝从老百姓到上层社会的普遍吃法， 最高端的吃法是把梨放在炉子上烧熟了吃，跟烤梨差不多。
6.葡萄酒工艺在唐朝获得提升，原因是唐朝灭了高昌国，获得了马乳葡萄种和葡萄酒的酿造方法。李世民还在皇宫里种了很多葡萄，还亲自参与葡萄酒的酿造。
7.唐朝之前，酿酒技术还不成熟，由于霉菌的原因，人们喝的酒是绿色的，到了唐朝，人们改革了制酒技术，造出了琥珀色的酒，但是这些酒的度数还是很低，酒精含量不超过3%，所以李白才能喝的那么豪迈。白居易的那首“绿蚁新醅酒，红泥小火炉”是个很好的证明，绿蚁就是酒里的霉菌，绿渣子，真正的白酒是元代之后才出现的，人们发明了蒸馏法。
8.唐朝皇宫里，夏天的时候流行吃清风饭，配料有米饭、冰片粉、牛酪浆、龙睛粉。御厨做完之后，把饭放入金缸里，缸泡在冰水池里，饭凉了之后再拿去给皇帝妃子们享用，可以说是唐朝的哈根达斯了。
9.李白那句“不及汪伦送我情”，汪伦到底送了啥？ 汪伦送给李白西域的名马八匹，官锦十端。。。咱们小学的时候，考试还会写表达了李白和汪伦淳朴真诚的友谊。。。送了那么多东西，我要是李白，我也要来一首赠汪伦啊…
10.在唐朝以前，衡度是十六黍为一豆，六豆为一铢，三铢为一锱，二十四铢为一两。唐高祖的“开元通宝”铜钱，重二铢四絫，十钱重一两，衡度才演变为十进制。
11.唐朝的宰相元载被抄家，光胡椒就有八百石，相当于60多吨。。。胡椒在当时是奢侈品，存着可以升值涨价，等同于黄金，不过在家里放60多吨胡椒也是蛮屌的。。。
12.唐朝贵族是这样喝茶的，先把芽茶蒸过捣碎，做成茶饼干燥保存，用时将茶饼在火上烘烤一下，碾成碎末，用泉水、兽炭烹茶，加入吴盐饮用，这种喝法后来传到了日本，日本的贵族也是那么喝的，这种喝法演变成了后来的抹茶。咱们现在喝茶的方法，也就是泡茶，是明朝之后才出现的，明朝之前，中国人喝茶五花八门。
13.唐朝的白银不用作货币，所以关于唐代的电视剧里如果出现吃饭拿白银付款，那。。。
14.在唐朝，“东西”指的是方位，没有指物品，指物品的意思是宋代之后了。
15.唐朝的蒸饼是馒头。
16.李世民的爷爷叫李虎，为了避“虎”讳，虎改叫做兽，武，彪（谢谢好友指正）
17.奶酪是唐朝北方人的日常饮品，而且物美价廉。
18.睢阳之战，唐军在防守睢阳期间吃掉了三万的老百姓。。。
19.唐朝初年，军阀朱粲的军队所到之处，人烟绝迹（军队吃人肉），之后朱粲归顺大唐，唐朝派来使者，这个使者缺心眼，一直问朱粲人肉是什么味道，朱粲恼羞成怒，将使者剁成肉酱，因此得罪了唐朝，只得投奔王世充，公元621年朱粲被李世民杀于洛阳。
20.李世民的贴身丘行恭，在处置谋反的刘兰成时，他化成中华小当家，在同事和下属面前直播烹饪，把刘兰成的心脏和肝脏煮了吃。。。
21.唐朝人喜欢在樱桃上淋上蔗浆，蔗浆就是浓缩的甘蔗汁，这是当时长安城的一道高档甜品。
22.唐朝有条件的老百姓，夏天的时候会去冰窖买冰块，把冰块敲碎，浇上蔗浆，制成刨冰。
关于评论里有人好奇储存冰块的方法，是酱的，冬天的时候，人们会去河里或者高山上采冰，然后存入冰窖，冰窖说白了就是封闭的地下室，夏天的时候再拿出来用，长安城夏天的时候还可以去终南山采集冰雪。要么就是把冰块放入深井里，可以说是“深井冰”了；唐朝末年，人们发现硝石可以制冰，从那以后，制冰就更加容易了。
23. 盛唐时期流行一种叫“泼寒胡戏”的活动，就是一大群裸体青年，在大街上戴着稀奇古怪的面具，在乐器和路人的喧闹声中用冷水互相泼，也泼向围观的人群，十分热闹，不过后来唐朝有关部门觉得太有伤风化了，就给禁止了。
24.唐朝有道高端名菜叫做浑羊殁忽，非常高级，只有真正的土豪才吃得起。做法就是把鹅宰好，毛拔干净，往肚子里塞上肉和糯米饭以及一些调料，接下来，把鹅放在整只羊的肚子里，然后把羊肚子缝好，拿去烤，烤熟之后只吃鹅，不吃羊。
25.唐朝人喝茶要放一点盐，放点姜，还放苏椒和酪，有些地方的小清新还会放桂皮。。。这些茶水可以拿去做茶叶蛋了，23333
26.日本人生鱼片的吃法是唐朝人传过去的，唐朝人吃生鱼片喜欢蘸蒜，此外，唐朝人吃东西特别喜欢加蒜，要么就是拌橙子酱，不知道为什么。。。。
27.唐朝的时候，就已经有送外卖的服务了，《唐国史补》里面有记载。。。
28. 武则天担任过唐朝女子马球队的队长。。。
29.唐朝是不可以吃鲤鱼的，因为鲤跟李同音，毕竟是李唐王朝，朝廷为了避讳，规定全国上下不可以吃鲤鱼，违者仗刑，但是挡不住，中国人什么时候对美食停止过脚步了？
30.有个印度阿三，叫那罗迩娑婆寐，他吹牛逼说自己活了200多岁，能研发出长生不老的灵丹妙药，这哥们还说印度有一种可以融化一切的药水，必须得先用骆驼的骷髅装，然后再装进葫芦里，他还说生产这种药水的地方，都有石像守护，谁泄露了秘密就会死，遗憾的是，这个印度阿三得到了李世民的信任，被封为宫廷药师。。。
31.唐代的《茶赋》里有一句话，“滋饭蔬之精素，攻肉食之膻腻”，说的是啥？ 茶泡饭，这个东西后来传到日本了。
Dad asks you for an essay about him
Most fathers just ask for normal gifts on Father’s Day, like those greeting cards you can find at stores. My father, however, has asked for the same specific thing since I was 7: An essay about him. I’ve always dreaded Father’s Day because of this. Every time I try to write an essay, I have no idea how to start, and then I have no idea how to continue, and I’m sure that if I do continue the essay will be horrible. In fact, I’m thinking that my essay is horrible right now. But my dad stubbornly insists on making me write one essay per year about him on Father’s Day.
My father doesn’t do this for the sake of writing essays, though. He doesn’t want me to write an essay just to compliment him. He wants to help me learn. This isn’t just learning to write, this is learning to become more confident, learning to be able to express yourself, learning to overcome my fears of being humiliated by writing a poorly written essay. Each year, I begin my essay the same way, but I end them differently every time. I end them better each time.
My father helps me learn by making me write essays, but also by taking me to fencing, cello classes, Lego Robotics or whatever else I happen to be interested in. He does this by buying books, or taking me to school, or helping me with my homework, or by running to my bed in the middle of the night. He has done this so many times that I often let what he does fade into the background of life and take this for granted, even though each time he does something it takes up his time and energy. Each event is small, but he has done this and cared for me for my entire life. Because of this I’d like to thank him…even though sometimes I wish he didn’t help this much, like every time I start writing my essay for Father’s Day.

David vs Goliath
This is a section in a book. In case that you are interested in the book, please let me know.
=========
“IT WAS REALLY RANDOM. I MEAN, MY FATHER HAD NEVER PLAYED BASKETBALL BEFORE.”
When Vivek Ranadivé decided to coach his daughter Anjali’s basketball team, he settled on two principles. The first was that he would never raise his voice. This was National Junior Basketball— the Little League of basketball. The team was made up mostly of twelve-year-olds, and twelve-yearolds, he knew from experience, did not respond well to shouting. He would conduct business on the basketball court, he decided, the same way he conducted business at his software firm. He would speak calmly and softly, and he would persuade the girls of the wisdom of his approach with appeals to reason and common sense.
The second principle was more important. Ranadivé was puzzled by the way Americans play basketball. He is from Mumbai. He grew up with cricket and soccer. He would never forget the first time he saw a basketball game. He thought it was mindless. Team A would score and then immediately retreat to its own end of the court. Team B would pass the ball in from the sidelines and dribble it into Team A’s end, where Team A was patiently waiting. Then the process would reverse itself.
A regulation basketball court is ninety-four feet long. Most of the time, a team would defend only about twenty-four feet of that, conceding the other seventy feet. Occasionally teams played a full-court press—that is, they contested their opponent’s attempt to advance the ball up the court. But they did it for only a few minutes at a time. It was as if there were a kind of conspiracy in the basketball world about the way the game ought to be played, Ranadivé thought, and that conspiracy had the effect of widening the gap between good teams and weak teams. Good teams, after all, had players who were tall and could dribble and shoot well; they could crisply execute their carefully prepared plays in their opponent’s end. Why, then, did weak teams play in a way that made it easy for good teams to do the very things that they were so good at?
Ranadivé looked at his girls. Morgan and Julia were serious basketball players. But Nicky, Angela, Dani, Holly, Annika, and his own daughter, Anjali, had never played the game before. They weren’t all that tall. They couldn’t shoot. They weren’t particularly adept at dribbling. They were not the sort who played pickup games at the playground every evening. Ranadivé lives in Menlo Park, in the heart of California’s Silicon Valley. His team was made up of, as Ranadivé put it, “little blond girls.” These were the daughters of nerds and computer programmers. They worked on science projects and read long and complicated books and dreamed about growing up to be marine biologists. Ranadivé knew that if they played the conventional way—if they let their opponents dribble the ball up the court without opposition—they would almost certainly lose to the girls for whom basketball
was a passion. Ranadivé had come to America as a seventeen-year-old with fifty dollars in his pocket. He was not one to accept losing easily. His second principle, then, was that his team would play a real full-court press—every game, all the time. The team ended up at the national championships. “It was really random,” Anjali Ranadivé said. “I mean, my father had never played basketball before.”
Vivek Ranadivé’s basketball team played in the National Junior Basketball seventh-and-eighth-grade division representing Redwood City. The girls practiced at Paye’s Place, a gym in nearby San Carlos. Because Ranadivé had never played basketball, he recruited a couple of experts to help him. The first was Roger Craig, a former professional athlete who worked for Ranadivé’s software company.* After Craig signed on, he recruited his daughter Rometra, who had played basketball in college. Rometra was the kind of person you assigned to guard your opponent’s best player in order to render her useless. The girls on the team loved Rometra. “She has always been like my big sister,” Anjali Ranadivé said. “It was so awesome to have her along.”
Redwood City’s strategy was built around the two deadlines that all basketball teams must meet in order to advance the ball. The first is the time allotted for the inbounds pass. When one team scores, a player from the other team takes the ball out-of-bounds and has five seconds to pass it to a teammate on the court. If that deadline is missed, the ball goes to the other team. Usually that’s not an issue, because teams don’t hang around to defend against the inbounds pass. They run back to their own end. Redwood City did not do that. Each girl on the team closely shadowed her counterpart. When some teams play the press, the defender plays behind the offensive player she’s guarding in order to impede her once she catches the ball. The Redwood City girls, by contrast, played a more aggressive, highrisk strategy. They positioned themselves in front of their opponents to prevent them from catching the inbounds pass in the first place. And they didn’t have anyone guard the player throwing the ball in. Why bother? Ranadivé used that extra player as a floater who could serve as a second defender against the other team’s best player.
“Think about football,” Ranadivé said. “The quarterback can run with the ball. He has the whole field to throw to, and it’s still damned difficult to complete a pass.” Basketball was harder. A smaller court. A five-second deadline. A heavier, bigger ball. As often as not, the teams Redwood City was playing against simply couldn’t make the inbounds pass within the five-second limit. Or else the inbounding player, panicked by the thought that her five seconds were about to be up, would throw the ball away. Or her pass would be intercepted by one of the Redwood City players. Ranadivé’s girls were maniacal.
The second deadline in basketball requires a team to advance the ball across midcourt into its opponent’s end within ten seconds, and if Redwood City’s opponents met the first deadline and were able to make the inbounds pass in time, the girls would turn their attention to the second deadline. They would descend on the girl who caught the inbounds pass and “trap” her. Anjali was the designated trapper. She’d sprint over and double-team the dribbler, stretching her long arms high and wide. Maybe she’d steal the ball. Maybe the other player would throw it away in a panic—or get bottled up and stalled, so that the ref would end up blowing the whistle.
“When we first started out, no one knew how to play defense or anything,” Anjali said. “So my dad said the whole game long, ‘Your job is to guard someone and make sure they never get the ball on inbounds plays.’ It’s the best feeling in the world to steal the ball from someone. We would press and steal, and do that over and over again. It made people so nervous. There were teams that were a lot
better than us, that had been playing a long time, and we would beat them.”
The Redwood City players would jump ahead 4–0, 6–0, 8–0, 12–0. One time they led 25–0. Because they typically got the ball underneath their opponent’s basket, they rarely had to attempt the low-percentage, long-range shots that require skill and practice. They shot layups. In one of the few games that Redwood City lost that year, only four of the team’s players showed up. They pressed anyway. Why not? They lost by only 3 points.
“What that defense did for us is that we could hide our weaknesses,” Rometra Craig said. “We could hide the fact that we didn’t have good outside shooters. We could hide the fact that we didn’t have the tallest lineup. Because as long as we played hard on defense, we were getting steals and getting easy layups. I was honest with the girls. I told them, ‘We’re not the best basketball team out there.’ But they understood their roles.” A twelve-year-old girl would go to war for Rometra. “They were awesome,” she said.
Lawrence attacked the Turks where they were weak—along the farthest, most deserted outposts of the railroad—and not where they were strong. Redwood City attacked the inbounds pass, the point in a game where a great team is as vulnerable as a weak one. David refused to engage Goliath in close quarters, where he would surely lose. He stood well back, using the full valley as his battlefield. The girls of Redwood City used the same tactic. They defended all ninety-four feet of the basketball court. The full-court press is legs, not arms. It supplants ability with effort. It is basketball for those who, like Lawrence’s Bedouin, are “quite unused to formal warfare, whose assets [are] movement, endurance, individual intelligence…courage.”
“It’s an exhausting strategy,” Roger Craig said. He and Ranadivé were in a conference room at Ranadivé’s software company, reminiscing about their dream season. Ranadivé was at the whiteboard, diagramming the intricacies of the Redwood City press. Craig was sitting at the table.
“My girls had to be more fit than the others,” Ranadivé said.
“He used to make them run!” Craig said, nodding.
“We followed soccer strategy in practice,” Ranadivé said. “I would make them run and run and run. I couldn’t teach them skills in that short period of time, and so all we did was make sure they were fit and had some basic understanding of the game. That’s why attitude plays such a big role in this, because you’re going to get tired.”
Ranadivé said “tired” with a note of approval in his voice. His father was a pilot who was jailed by the Indian government because he wouldn’t stop challenging the safety of the country’s planes. Ranadivé went to MIT after he saw a documentary on the school and decided that it was perfect for him. This was in the 1970s, when going abroad for undergraduate study required the Indian government to authorize the release of foreign currency, and Ranadivé camped outside the office of the governor of the Reserve Bank of India until he got his money. Ranadivé is slender and fine-boned, with a languorous walk and an air of imperturbability. But none of that should be mistaken for nonchalance. The Ranadivés are relentless.
He turned to Craig. “What was our cheer again?”
The two men thought for a moment, then shouted out happily, in unison: “One, two, three, attitude!”
The whole Redwood City philosophy was based on a willingness to try harder than anyone else.
“One time, some new girls joined the team,” Ranadivé said, “and so in the first practice I had, I was telling them, ‘Look, this is what we’re going to do,’ and I showed them. I said, ‘It’s all about attitude.’ And there was this one new girl on the team, and I was worried that she wouldn’t get the whole attitude thing. Then we did the cheer and she said, ‘No, no, it’s not one, two, three, attitude. It’s one, two, three, attitude, hah!’ ”—at which point Ranadivé and Craig burst out laughing.
=========
“IT WAS REALLY RANDOM. I MEAN, MY FATHER HAD NEVER PLAYED BASKETBALL BEFORE.”
When Vivek Ranadivé decided to coach his daughter Anjali’s basketball team, he settled on two principles. The first was that he would never raise his voice. This was National Junior Basketball— the Little League of basketball. The team was made up mostly of twelve-year-olds, and twelve-yearolds, he knew from experience, did not respond well to shouting. He would conduct business on the basketball court, he decided, the same way he conducted business at his software firm. He would speak calmly and softly, and he would persuade the girls of the wisdom of his approach with appeals to reason and common sense.
The second principle was more important. Ranadivé was puzzled by the way Americans play basketball. He is from Mumbai. He grew up with cricket and soccer. He would never forget the first time he saw a basketball game. He thought it was mindless. Team A would score and then immediately retreat to its own end of the court. Team B would pass the ball in from the sidelines and dribble it into Team A’s end, where Team A was patiently waiting. Then the process would reverse itself.
A regulation basketball court is ninety-four feet long. Most of the time, a team would defend only about twenty-four feet of that, conceding the other seventy feet. Occasionally teams played a full-court press—that is, they contested their opponent’s attempt to advance the ball up the court. But they did it for only a few minutes at a time. It was as if there were a kind of conspiracy in the basketball world about the way the game ought to be played, Ranadivé thought, and that conspiracy had the effect of widening the gap between good teams and weak teams. Good teams, after all, had players who were tall and could dribble and shoot well; they could crisply execute their carefully prepared plays in their opponent’s end. Why, then, did weak teams play in a way that made it easy for good teams to do the very things that they were so good at?
Ranadivé looked at his girls. Morgan and Julia were serious basketball players. But Nicky, Angela, Dani, Holly, Annika, and his own daughter, Anjali, had never played the game before. They weren’t all that tall. They couldn’t shoot. They weren’t particularly adept at dribbling. They were not the sort who played pickup games at the playground every evening. Ranadivé lives in Menlo Park, in the heart of California’s Silicon Valley. His team was made up of, as Ranadivé put it, “little blond girls.” These were the daughters of nerds and computer programmers. They worked on science projects and read long and complicated books and dreamed about growing up to be marine biologists. Ranadivé knew that if they played the conventional way—if they let their opponents dribble the ball up the court without opposition—they would almost certainly lose to the girls for whom basketball
was a passion. Ranadivé had come to America as a seventeen-year-old with fifty dollars in his pocket. He was not one to accept losing easily. His second principle, then, was that his team would play a real full-court press—every game, all the time. The team ended up at the national championships. “It was really random,” Anjali Ranadivé said. “I mean, my father had never played basketball before.”
Vivek Ranadivé’s basketball team played in the National Junior Basketball seventh-and-eighth-grade division representing Redwood City. The girls practiced at Paye’s Place, a gym in nearby San Carlos. Because Ranadivé had never played basketball, he recruited a couple of experts to help him. The first was Roger Craig, a former professional athlete who worked for Ranadivé’s software company.* After Craig signed on, he recruited his daughter Rometra, who had played basketball in college. Rometra was the kind of person you assigned to guard your opponent’s best player in order to render her useless. The girls on the team loved Rometra. “She has always been like my big sister,” Anjali Ranadivé said. “It was so awesome to have her along.”
Redwood City’s strategy was built around the two deadlines that all basketball teams must meet in order to advance the ball. The first is the time allotted for the inbounds pass. When one team scores, a player from the other team takes the ball out-of-bounds and has five seconds to pass it to a teammate on the court. If that deadline is missed, the ball goes to the other team. Usually that’s not an issue, because teams don’t hang around to defend against the inbounds pass. They run back to their own end. Redwood City did not do that. Each girl on the team closely shadowed her counterpart. When some teams play the press, the defender plays behind the offensive player she’s guarding in order to impede her once she catches the ball. The Redwood City girls, by contrast, played a more aggressive, highrisk strategy. They positioned themselves in front of their opponents to prevent them from catching the inbounds pass in the first place. And they didn’t have anyone guard the player throwing the ball in. Why bother? Ranadivé used that extra player as a floater who could serve as a second defender against the other team’s best player.
“Think about football,” Ranadivé said. “The quarterback can run with the ball. He has the whole field to throw to, and it’s still damned difficult to complete a pass.” Basketball was harder. A smaller court. A five-second deadline. A heavier, bigger ball. As often as not, the teams Redwood City was playing against simply couldn’t make the inbounds pass within the five-second limit. Or else the inbounding player, panicked by the thought that her five seconds were about to be up, would throw the ball away. Or her pass would be intercepted by one of the Redwood City players. Ranadivé’s girls were maniacal.
The second deadline in basketball requires a team to advance the ball across midcourt into its opponent’s end within ten seconds, and if Redwood City’s opponents met the first deadline and were able to make the inbounds pass in time, the girls would turn their attention to the second deadline. They would descend on the girl who caught the inbounds pass and “trap” her. Anjali was the designated trapper. She’d sprint over and double-team the dribbler, stretching her long arms high and wide. Maybe she’d steal the ball. Maybe the other player would throw it away in a panic—or get bottled up and stalled, so that the ref would end up blowing the whistle.
“When we first started out, no one knew how to play defense or anything,” Anjali said. “So my dad said the whole game long, ‘Your job is to guard someone and make sure they never get the ball on inbounds plays.’ It’s the best feeling in the world to steal the ball from someone. We would press and steal, and do that over and over again. It made people so nervous. There were teams that were a lot
better than us, that had been playing a long time, and we would beat them.”
The Redwood City players would jump ahead 4–0, 6–0, 8–0, 12–0. One time they led 25–0. Because they typically got the ball underneath their opponent’s basket, they rarely had to attempt the low-percentage, long-range shots that require skill and practice. They shot layups. In one of the few games that Redwood City lost that year, only four of the team’s players showed up. They pressed anyway. Why not? They lost by only 3 points.
“What that defense did for us is that we could hide our weaknesses,” Rometra Craig said. “We could hide the fact that we didn’t have good outside shooters. We could hide the fact that we didn’t have the tallest lineup. Because as long as we played hard on defense, we were getting steals and getting easy layups. I was honest with the girls. I told them, ‘We’re not the best basketball team out there.’ But they understood their roles.” A twelve-year-old girl would go to war for Rometra. “They were awesome,” she said.
Lawrence attacked the Turks where they were weak—along the farthest, most deserted outposts of the railroad—and not where they were strong. Redwood City attacked the inbounds pass, the point in a game where a great team is as vulnerable as a weak one. David refused to engage Goliath in close quarters, where he would surely lose. He stood well back, using the full valley as his battlefield. The girls of Redwood City used the same tactic. They defended all ninety-four feet of the basketball court. The full-court press is legs, not arms. It supplants ability with effort. It is basketball for those who, like Lawrence’s Bedouin, are “quite unused to formal warfare, whose assets [are] movement, endurance, individual intelligence…courage.”
“It’s an exhausting strategy,” Roger Craig said. He and Ranadivé were in a conference room at Ranadivé’s software company, reminiscing about their dream season. Ranadivé was at the whiteboard, diagramming the intricacies of the Redwood City press. Craig was sitting at the table.
“My girls had to be more fit than the others,” Ranadivé said.
“He used to make them run!” Craig said, nodding.
“We followed soccer strategy in practice,” Ranadivé said. “I would make them run and run and run. I couldn’t teach them skills in that short period of time, and so all we did was make sure they were fit and had some basic understanding of the game. That’s why attitude plays such a big role in this, because you’re going to get tired.”
Ranadivé said “tired” with a note of approval in his voice. His father was a pilot who was jailed by the Indian government because he wouldn’t stop challenging the safety of the country’s planes. Ranadivé went to MIT after he saw a documentary on the school and decided that it was perfect for him. This was in the 1970s, when going abroad for undergraduate study required the Indian government to authorize the release of foreign currency, and Ranadivé camped outside the office of the governor of the Reserve Bank of India until he got his money. Ranadivé is slender and fine-boned, with a languorous walk and an air of imperturbability. But none of that should be mistaken for nonchalance. The Ranadivés are relentless.

孩子的写作
第一重要的还是要多读。开卷有益。先不要多想写作，要让娃领略文学艺术的乐趣。在二三年级要开始看一些篇幅较长的纯文字（非卡通）的文学性比较强的作品。领进门以后就容易多了。选书的话，基本上学校里会推荐书单，另外scholastic有按年级推荐的书单。
读了以后要多想。可以跟娃讨论一下书里面什么地方写的好，或者比较一下类似作品，或者想象一下续集怎么写，如此种种。总之是帮助娃丰富对作品的感受，体验读书的乐趣。
读的多了以后，对写作质量肯定是有帮助的。但这是一个厚积薄发的过程，不要指望立竿见影。
今天再写一点。关于阅读材料的选择，不宜太多限制。不必盲目推荐名著。英文书籍非常丰富，没必要只读经典名著。小娃阅读能力还比较有限，不必读大部头，一切以激发兴趣为目的。从培养文学素养的角度，阅读一定量的小说是必须的。小时候不爱看小说也没有关系。随着阅读速度和理解能力的提高，娃一般迟早会开始喜欢读故事情节比较有趣的长故事。除小说之外，散文，政治评论，诗歌，都应该读一些。但是应以鼓励兴趣为主，避免过多压力，反而令娃反感。
阅读是写作的基础，但并不一定阅读好写作就一定好。这个现象在小学高年级和中学低年级比较常见，原因也很简单：欣赏和创作是不同性质的工作。喜欢听交响乐和演奏交响乐是完全不一样的事情。但是前者仍然是后者的基础，没有听音乐的基础，不可能有创作的能力。好比金字塔的高度取决于底部的大小，创造能力是受限制于欣赏能力的，这个是放之四海而皆准的真理。好比聋子不可能成为作曲家（什么？谁说的贝多芬？尼揍凯！）。再有一比，阅读好比是马钰传授的全真派内功，学了以后打架虽然不能马上派上用场，但对将来学打架的功夫学到什么深度绝对有极大的影响。所以我一定要把阅读放在最前面说。我看到一些家长的孩子已经到了高中了，跑来问怎么帮助孩子提高写作能力，虽然也未必就晚，但是这个基础实在是应该在之前就从阅读习惯开始培养的。
讲完打基础，可以讲点儿开始学写作。一开始无非是要求把事情交代清楚，When Where Who What Why How 这些要素讲明白就好了。叙述就按照时间顺序来，流水帐。这个时候要鼓励娃编故事，不管多么简单多么幼稚，语法拼写错误什么的都无所谓，主要是激发娃的创作兴趣。切忌吹毛求疵。基本上在小学三年级以后，可以开始写，逐渐培养写作习惯，不拘束于写作的体裁和内容，只要是写就可以，都可以锻炼书面表达能力。
到了一定程度，娃会不满足于写流水帐。这个时候可以引入一些新的概念。我给我娃的建议是，先按照时间顺序把事件一条条列出来，然后从逻辑和情感的角度出发，对前面列出的条目进行增删，顺序也可以进行调整，不再拘泥于时间顺序。这样的写作，目的已经不止于把事情交代清楚，而是为了传递某种情绪，讲述某种道理，求得某种认知。娃的鉴赏力如果到了这个深度的话，这一步是一点就透的。
=======
前天我接娃放学，娃说：听说四年级的统考要考作文了，会很难。我说：你作文不是写的很好嘛。他想了一下说：是的。
想想去年夏天的时候他最怕写作文，经常枯坐半个小时，一个字都写不出来，连构思都没有。在学校经常不能完成跟写作有关的作业。然而我那时就知道他能写。因为我见过他随性写的一些瞎编乱造的故事片段，文笔挺好的。他的障碍在于畏难，也疏于练习。
从去年夏天开始，我每周至少让他写一篇练习作文。一点儿一点儿手把手的教，从怎么选择话题开始。有时候就给他一个命题，让他列几个可行的话题，并不真的写。或者给他一个话题，让他写提纲。写提纲的时候，先按照时间顺序把事情的节点列一下。然后再教他根据情绪的起伏和逻辑的因果来考虑突出哪些节点，忽略哪些节点，增加哪些时序之外的内容，是否调整节点之间的顺序以达到特殊效果。。。
可能因为他读的书多，对这些东西领悟的挺快。上学期他的老师每周都会布置一到两篇作文。开始的时候我需要帮他选择话题，指导他写提纲。到学期结束的时候，他基本已经可以自己完成全部内容了。不过我还是每周都会跟他讨论怎么想，怎么写。他的每篇作文写完了我都会看，然后给些评论。基本都是鼓励就是了。好些时候他写的东西确实能给我惊喜，或者会心一笑。学校的老师似乎也相当喜欢他的作文。基本每次都会给他很正面的评价，有时候还让他读给同学听。老师选了他一篇作文发表在他们的学生期刊上，这事儿也增加了他不少自信。
我推过他的东西不少，几乎都没有效果。这次在半年多的时间里，能够在作文这个单项上发生这么大的转变，我还是感到欣慰的。当然这里说不定学校的功劳更大。虽然咱娃水平跟牛娃们不能比，但他自己能进步总是好的，不去管是谁的功劳啦。我假期里想把他去年的作文笔记本都扫描了保存起来，一直没做。昨天得空把这事儿做了，把他的作文一页一页翻过去，未免心中生出些感触，特此记录一下。
