赢在起跑线上！不论是笨鸟还是聪明鸟，我们都先飞。

一、when, while和as1．When既可引导一个持续动作，也可引导一个短暂动作，可用于主句和从句动作同时发生或从句动作先于主句动作。当主句是将来时，从句的时态用现在时。（when在实际中用得最多）I told my children when Lincoln was your age he walked twelvemiles to school everyday. But my son said, “That’s nothing. When he was your age, he was president.”我告诉我的孩子：当林肯你那么大岁数时他每天走12英里去学校，我儿子说，“那没什么，当他你那么大岁数时已经当总统了”。there’s a side to President Reagan that people don’t know. When he was a young man, he read complete works of Shakespeare. Of course, when Reagan was young, Shakespeare hadn’t written all that里根总统还有一面人们并不知道，年轻时他曾读过莎士比亚全集——当然里根年轻时莎士比亚还没写那么多。注：讽刺里根读书少，岁数大。当when引导的时间状语从句为系表结构，而且其主语和主句的主语一致，其标语又是一个名词，就可以以as引导的省略句来代替when引导的从句。如：As a young man, he read complete works of Shakespeare.他年轻时读过莎士比亚全集。When the game is finished, the king and the pawn[卒] go into to the same box.游戏结束时，国王和士兵进入同一个盒子。注：人生就象一场游戏，游戏结束时，亿万富翁也好，平头百姓也好都进入一样大小的棺材（或骨灰盒）。Finish为短暂动作，从句动作先于主句动作。场景再现：在筹集善款的晚会上，可以这么调侃：How noisy an audience can be when you ask for quiet ____ and how quiet it can be when you ask for money.（多么令人惊奇啊，）当你要求安静时听众乱烘烘的——当你要钱时全场一片寂静。
