祈使句

★肯定句：動詞原型

Be quiet.

Be careful.

祈使句中如果有喚語，一定要用逗號隔開，放在句首或者句尾：

Sit down here, Tom.

Mary, give me a book please.

★否定：Don't+動詞原型

Don't come here.

Don't sit down.

Don't stand up.

Don't give me it.

let sb. do 讓某人做

Let me pass.

Let us have a rest.

Let's have a rest.

反意疑問：

Let us go out for a drink, will you?

倒裝句：

so/neither的倒裝

eg: He can swim. So can I.

She didn't go to class. Neither did I.

結(jié)構(gòu)：

so/neither+be+ 主語

so/neither+助動詞+ 主語

so/neither+情態(tài)動詞+ 主語

助動詞：

一般現(xiàn)在時: do, does/am, is, are

現(xiàn)在進(jìn)行時: am, is, are

一般過去時: did

現(xiàn)在完成時: have, has

一般將來時: will, shall

過去進(jìn)行時: was, were

過去完成時: had

感嘆句：

1) What +名詞+主語+謂語

What tall buildings they are!

2) How +形容詞+主語+謂語

? 在口語中，感嘆句的主語和謂語常常省略：
