1．(P8)It was at ten ’clck tday that the first f all Time Machines began its career.【翻译】今天十点钟，第一台时间机器开始了它的工作生涯。【句式剖析】本句中的“It ”是一个常用的强调句型。在本句中，强调时间状语“at ten ’clck tday”。
【归纳拓展】“It is＋被强调部分＋that＋其他”是一个常用的强调句型。被强调的部分可以是句子的主语、宾语或状语。使用强调句型时，应注意如下几点：(1)需要强调的成分要放到is/was后面。不论被强调部分是单数还是复数，It后面的be动词都与It保持一致，用is或was。(2)英语里常可被强调的是方式状语、地点状语或时间状语。这时，应注意不要把这个被强调部分看成定语从句的先行词，而误用where或when。
(3)“”的强调句。nt和until作为固定结构使用时，往往是分开的，但是如果要强调，则会合在一起，即构成“It is/was nt ”，此时，主句的否定结构在强调句中要变为肯定结构。(4)如果强调的是一般疑问句中的某个成分，则强调句也要改用相应的一般疑问句的结构“Is/Was＋it＋被强调部分＋that＋其他？”。(5)如果要对特殊疑问句中的特殊疑问词进行强调，则强调句应用“特殊疑问词＋was/is it＋that＋其他？”。
(6)当被强调部分是表示人的词语时，也可用wh。It is Mike and his mther that/wh are ging t pay a visit t Guilin.It is in the gym that he ften plays basketball with his classmates n weekends.It is n weekends that he ften plays basketball in the gym.It is nt until midnight that his father will cme back every day.Where was it that yu met Tm?

【归纳拓展】(1)as if意为“似乎，好像”，可引导表语从句或状语从句。(2)as if从句中的谓语动词可用陈述语气，也可用虚拟语气。(3)as if从句如果表示虚拟语气，则从句的谓语动词形式用动词过去式，表示与主句谓语的动作同时发生的情况；从句的谓语动词形式用“had＋过去分词”，表示先于主句谓语的动作之前发生的动作。
