1、强调句结构常考的强调句结构是it引导的句子。 It is (was)被强调部分+ that (who) +句子 其他部分。此结构强调的成分仅限于主语，宾语和状语。It is from the sun that we get light and heat.It was not until I had read your letter that I understood the true state of affairs. 典型例题1) It was last night _ I see the comet.A. the time B. when C. that D. which答案C.强调句的结
2、构是：It +be +强调部分+ that (who) +主谓句。 强调句的 连词只有两个，that和who。当强调的部分是人，且为句子的主语时，才用who，其余用 that。原句： My father did the experiment in the lab yesterday evening.强调主语： It was my father who did the experiment in the lab yesterday evening. 强调宾语： It was the experiment that my fatherdid in the lab yesterday evening
3、. 强调时间： It was yesterday evening that my father did the experiment in the lab.(注意不用when)强调地点： It was in the lab that my father did the experiment yesterday evening.2) It is ten years _ Miss Green returned to Canada.A. that B. when C. since D. as答案C.考点是连词用法。本题易误选为A. that.其实本句不是强调句。若是，去掉 It bet ha t还应
4、是一个完整的句子。而本句去掉I t ist ha t,只剩下ten years Miss Green returned to Canada.不成句。因此本句不是强调句。It is /was + 时间+ since 其中 is has been was had been.感叹句结构what修饰名词，how感叹句通常有what, how引导，表示赞美、惊叹、喜悦、等感情。 修饰形容词，副词或动词，感叹句结构主要有以下几种：掌握它的搭配，即掌握了感叹句的重点。How +形容词+ a +名词+陈述语序How+形容词或副词+陈述语序What +名词+陈述语序What+a+形容词+名词+陈述语序What+
5、 形容词+复数名词+陈述语序What+ 形容词+不可数名词+陈述语序How clever a boy he is!How lovely the baby is!What noise they are making!What a clever boy he is!What wonderful ideas (we have)!What cold weather it is!感叹句的省略形式为：What a clever boy (he is)!典型例题1)_ food youve cooked!A. How a nice B. What a nice C. How nice D. What nic
6、e答案D.由于How修饰形容词，副词;what修饰名词。且food为不可数名词，因此A, B排除。C How + adj.后面不能再加名词，因此只有D正确，其句型为What + adj. +n.(不可 数)2) _terrible weather weve been having these days!A. What B. What a C. How D. How a答案A. weather为不可数名词，B，D排除。C为how + adj.后面不应有名词。只有A， 符合句型 What +形容词+不可数名词。3) - I had!- You really suffered a lot.A. Wh
7、at a time B. What time C. How a time D. how time答案 A. 感叹句分两类：1： What + n.+主谓部分2： How + adj. / adv. / v.+主谓部分。本题属第一种，但省略了 bad，相对于 What a bad time I had! 这是个习惯用语。祈使句结构祈使句用以表达命令，要求，请求，劝告等。1)祈使句有两种类型，一种是以动词原形开头，在动词原形之前加do (但只限于省略第二人称主语的句子)。Take this seat.Do be careful.否定结构：Dont move.Dont be late.2) 第二种祈使句以 let 开头。Let 的反意疑问句a. Lets 包括说话者Lets have another try， shall we / shant we?= Shall we have another try?b. Let us 不包括说话者Let us have another try， will you / wont you?= Will you please let us have another try?否定结构：Lets not talk of that matter.Let us not talk of that matter.
