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:

Don't move.

Don't be late.

2) 第二种祈使句以let开头。Let 的反意疑问句

a. Let's 包括说话者 

Let's have another try,shall we / shan't we?

= Shall we have another try?

b. Let us 不包括说话者

Let us have another try,will you / won't you?

= Will you please let us have another try?

否定结构:

Let's not talk of that matter.

Let us not talk of that matter.

感叹句结构

感叹句通常有what, how引导,表示赞美、惊叹、喜 悦、等感情。

what修饰名词,how 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 clever a boy he is!  
How+形容词或副词+陈述语序   How lovely the baby is!  
What +名词+陈述语序   What noise they are making!  
What+a+形容词+名词+陈述语序   What a clever boy he is!  
What+ 形容词+复数名词+陈述语序   What wonderful ideas (we have)!  
What+ 形容词+不可数名词+陈述语序   What cold weather it is!  
感叹句的省略形式   What a clever boy (he is)!  

典型例题

1)___ food you've cooked!

A. How a nice  B. What a nice  C. How nice  D. What nice

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 we've 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. What 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。

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 father did in the lab yesterday evening.

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.
