1．(P9)When peple started creating their wn avatars, they discvered that they were ging t have the pwer t create new identities that did nt lk r act like their real selves at all.【翻译】人们开始创设自己的虚拟形象时，他们发现，他们将有能力创设行为或动作根本不像他们自己的崭新形象。
【考点提炼】该句子中When peple started creating their wn avatars为when引导的时间状语从句。值得一提的是，这是一个复合句。主句的主谓结构分别为they和 discvered，第一个that引导的是宾语从句，而在这个宾语从句中，又包含一个由that 引导的定语从句that did nt lk r act like their real selves at all，修饰名词短语new identities。
【归纳拓展】when引导时间状语从句时，从句的动作可与主句的动作同时发生，也可先于主句的动作发生。当表示两个动作同时发生时，when可与as, while互换。●while引导时间状语从句时，从句谓语动词用延续性动词，表示主句的动作在从句的动作过程中发生。●as引导时间状语从句时，强调从句的动作与主句的动作同时发生，可译为“……时”；“一边……一边……，随着”。
Things were different when I was a child.我小时候情况与现在不同。I went swimming while the thers played tennis.我去游泳，其余的人都打网球去了。He drpped the glass as he std up.他站起来时，把杯子摔了。※【温馨提示】如果主句用一般将来时，时间状语从句通常用一般现在时表示将来，即遵循“主将从现”原则。
【针对练习】选词填空(while; as; when，每词限用一次)(1) ________ I lived there, I used t g t the seashre n Sundays.(2)Please dn’t talk s lud ________ thers are wrking.(3)________ time ges n, it’s getting warmer and warmer.【答案】(1)When　(2)while　(3)As
2．(P9)Sme users wrry that they are spending s much time in virtual wrlds that they are becming afraid f …【翻译】一些用户担心它们在虚拟世界中花费太多时间，以至于开始害怕……【考点提炼】该句子中s…that…表示“如此……以至于……”，引导结果状语从句。
【巧学助记】s/such…that…句型中s与such的选用规则如下：名前such，形副s；多多少少(many/much/few/little)也用s；little一词特殊记，“小”用such，“少”用s。
【针对练习】完成句子(1)There was ________ ________ ________ t d that everybdy gt bred.有这么多的事要做以至于人人都感到厌烦了。(2)They are ________ ________ ________ ________ we all lve them.这些孩子如此好，我们都很喜欢他们。【答案】(1)s much wrk　(2)such gd children that
