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)。

2) 第二种祈使句以let开头。
Let 的反意疑问句

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.
13.2 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+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+ 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 you've cooked!
A. How a niceB. What a niceC. 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 aC. 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 timeB. 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。
13.3 强调句结构
It is (was) 被强调部分+ that (who) + 句子其他部分。
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 timeB.when C.thatD.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.
2)It is ten years ___ Miss Green returned to Canada.
A. thatB. 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 be… that还应是一个完整的句子。而本句去掉 'It is…that'，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.
13.4 用助动词进行强调
强调句还有一种类型，就是用助动词do (did，does) 强调谓语。
She does like this horse.她的确喜欢这匹马。
Please do take care of yourself. 千万保重。
13.5 反意疑问句
I'm as tall as your sister，aren't I?
I wish to have a word with you, may I?

Some plants never blown (开花), do they ?

2019年大学英语四级考试语法：倒装
全部倒装是只将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和一般过去时。常见的结构有：
1) here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run。
There goes the bell.
Then came the chairman.
Here is your letter.
2) 表示运动方向的副词或地点状语置于句首，谓语表示运动的动词。
Out rushed a missile from under the bomber.
Ahead sat an old woman.
注意：上述全部倒装的句型结构的主语必须是名词，如果主语是人称代词则不能完全倒装。
Here he comes.Away they went.
答案A. 这是一个倒装问题。当否定词语置于句首以表示强调时，其句中的主谓须用倒装结构。 这些否定词包括no, little, hardly, seldom, never, not only, not until等。本题的正常语序是 Smoking is permitted in the meeting-room at no time.
2) Not until the early years of the 19th century ___ what heat is.
A. man did know B. man know C. didn't man know D. did man know
答案D. 看到Not until…的句型，我们知道为一倒装句，答案在C，D 中选一个。
改写为正常语序为，Man did not know what heat is until the early years of the 19th. 现在将not提前，后面就不能再用否定了,否则意思就变了。
如 Not only…but also, Hardly/Scarcely…when, No sooner… than
Not only did he refuse the gift, he also severely criticized the sender.
Hardly had she gone out when a student came to visit her.
No sooner had she gone out than a student came to visit her.
典型例题
No sooner___ than it began to rain heavily.
A. the game began B.has the game begun
C. did the game begin D.had the game begun
答案D. 以具有否定意义的副词放在句首时，一般采用倒装句(谓语前置)。这类表示否定意义的词有never, seldom, scarcely, little, few, not, hardly, 以及not only…but (also), no sooner…than, hardly… when scarcely… when等等。
注意：只有当Not only… but also连接两个分句时，才在第一个分句用倒装结构。如果置于句首的Not only… but also仅连接两个并列词语，不可用倒装结构。
Not only you but also I am fond of music.
Tom can speak French. So can Jack.
If you won't go, neither will I.
典型例题
---Do you know Jim quarrelled with his brother?
---I don't know, _____.
A. nor don't I careB. nor do I careC. I don't care neitherD. I don't care also
答案：B. nor为增补意思"也不关心"，因此句子应倒装。A错在用 don't 再次否定， C neither 用法不对且缺乏连词。 D缺乏连词。
注意： 当so引出的句子用以对上文内容加以证实或肯定时，不可用倒装结构。意为"的确如此"。
Tom asked me to go to play football and so I did.
---It's raining hard.---So it is.
14.5 only在句首要倒装的情况
Only in this way, can you learn English well.
Only after being asked three times did he come to the meeting.
Only when he is seriously ill, does he ever stay in bed.
14.6 as, though 引导的倒装句
as / though引导的让步从句必须将表语或状语提前 (形容词, 副词, 分词, 实义动词提前)。
注意：
1) 句首名词不能带任何冠词。
2) 句首是实义动词, 其他助动词放在主语后。如果实义动词有宾语和状语, 随实义动词一起放在主语之前。
Try hard as he will, he never seems able to do the work satisfactorily.
注意:
让步状语从句中，有though，although时，后面的主句不能有but，但是 though 和yet可连用。
1) so… that 句型中的so 位于句首时，需倒装。
So frightened was he that he did not dare to move an inch.
2)在某些表示祝愿的句型中：
May you all be happy.
3)在虚拟语气条件句中从句谓语动词有were, had, should等词，可将if 省略，把 were, had, should 移到主语之前，采取部分倒装。
Were I you, I would try it again.
典型例题：
1) Not until the early years of the 19th century___ what heat is
A. man did know B. man knew C. didn't man know D. did man know
2) Not until I began to work ___ how much time I had wasted.
A. didn't I realizeB. did I realizeC. I didn't realizeD. I realize
答案为B。
3)Do you know Tom bought a new car?
I don't know, ___.
A. nor don't I care B. nor do I care
C. I don't care neitherD. I don't care also
解析：答案为B.句中的nor引出部分倒装结构，表示"也不"。由 so, neither, nor引导的倒装句，表示前一情况的重复出现。其中, so用于肯定句, 而 neither, nor 用在否定句中。
