Then we did what I consider to be the heart of the work: interviewed 1,100 children, boys and girls, ages seven to 12, all over the United States -- except for Silicon Valley, Boston and Austin because we knew that their little families would have millions of computers in them and they wouldn't be a representative sample.
然后我们进行了我认为是这次研究的心脏工作-- 采访1100个孩子，包括男孩和女孩， 全美地区，7岁到12岁的孩子， 除了硅谷，波士顿和奥斯汀， 因为我们知道那里的家庭拥有上百万的电脑， 他们不能成为具有代表性的例子。
