Be careful!
Please open your books.
Let me have a try.
Don’t open the door.
口诀：祈使句无主语，主语you常省去，动词原形当谓语，句首加don’t变否定。
二．感叹句：用what 和how引导，what 修饰的是名词，how修饰的是副词或形容词。
结构：What + a/an + 形+可数名词单数+（主语+谓语）！
What+形+可数名词复数/不可数名词+（主语+谓语）！
How+ 形/副 +（主语+谓语）！
_____a fine day it is! （What）
______useful work we have done! (What)
______careful my mother is! (How)
_______delicious bread it is! (What)
做题技巧：从右往左看，先划掉感叹号前的主语和谓语，剩下的是名词就用what,剩下的是形容词或者副词就用how。当然名词还需辨别可数不可数来确定是否有冠词a/an。
三．疑问句
疑问句有一般疑问句，特殊疑问句，选择疑问句，反意疑问句。
1. 一般疑问句：需要用yes或no来回答。结构：助动词+主语+谓语
Have you locked the door? Yes, I have.
Can you play the piano? Yes, I can.
2. 特殊疑问句：对句子中某一特殊部分提问的疑问句。
结构：特殊疑问词+ 一般疑问句
特殊疑问词：“非常6+1”，即6个W开头的疑问词（what/who/which/where/when/why）和1个H(How)开头的疑问词。
★how 与what的其他用法
⑴How much money do you want?
How many pictures did you buy?
How fast does he drive?
How often do you go abroad?
How many times do you go swimming in summer?
How soon will you come back?
How long have you been here？
（2）What number are you?
What color is your coat?
What time is it?
What day is it today?
3. 选择疑问句：提供两种或两种以上的情况，供对方选择的。选择疑问句不能用Yes和No回答，其答案只能是问句中提到的两个选择之一，如果考试中出现选择疑问句的选择题，选项中的Yes和No都要排除.
Do you like tea or coffee？ I like coffee.
Do you speak English or French? I speak English
Who runs faster, Tom or John? Tom.
4.反意疑问句：附在陈述句之后，对陈述句所说的事实或观点提出疑问。
结构：助动词/情态动词+主语， 前肯后否，前否后肯。
小升初英语考试中，一般以填空或者选择的形式，让孩子把反义疑问句后半句补充完整，从而来考察孩子对反义疑问句的掌握。
He likes playing football, doesn’t he?
He can speak English, can’t he?
★其他类型反意疑问句的用法
（1）There be 变成be there
There are 3 dogs, aren’t there?
There will be a meeting tomorrow, won’t there?
(2)祈使句后的反意疑问句：肯定祈使句的反意疑问句通常用will you 或won’t you, 否定祈使句的反意疑问句只用will you。
Pass me a book, will you?
Have another cup of tea, won’t you?
Don’t watch too much TV, will you?
★★Let’s go shopping, shall we?
Let us go now, will you?
(3)陈述部分用 no, no one, nothing, nobody, never, few, little, seldom, hardly, rarely,等否定含义的词时，疑问部分用肯定含义。

(4)陈述句的主语是不定代词everything, something, anything, nothing时，其后的反意疑问句主语用it。
Everything is right, isn’t it?

She usted to climb the mountain, usedn’t she?/didn’t she?
(7)陈述部分有had better + do, 疑问句部分用hadn't you?
You'd better read it by yourself, hadn't you?
(8) 含有宾语从句的主从复合句的反意疑问句中，简短问句一般反映主句中主、谓之间的关系。
She said that they were happy, didn’t she?
You think that you are funny, don’t you?___________?
但如果主句是I think, I believe等时，则简短问句反映的是that从句中主语与谓语之间的关系。
I think (that) he is serious, isn’t he?
I don’t think (that) he is serious, is he?
(9) 否定前缀不能视为否定词，其反意疑问句仍用否定形式。 This is important, isn't it? He is unhappy, isn’t he?
