上外附中小五班复习资料--第二册 Unit 3(2)
4 both, all 表示都，全部。
但是both 用于两者，all 用于三者或三者以上。
A and B are both….= __________ are both…=Both of ________ are……
A, B and C are all…..= ___________ are all…..= All of ________ are……
★5 as…as 和。。。一样
两个基本句型：
① A is as….as B A和B一样…
否定结构: A is not as…as B A没有B…
He is as clever as you.
You are not as/so lazy as him.
②A does sth as…..as B
否定结构：A doesn’t do sth as … as B
He does his homework as carefully as you.
I don’t run as fast as you.
第一个和第二个句型有什么不同之处？
结论：如果动词部分是使用的Be动词或感官动词（feel, taste, sound, look, smell），as..as中间用形容词；
若动词部分是实义动词，则后面使用副词。
练习：
这部电影没有那部电影有趣。

★6 enough adv. 足够地，充分地
两个重点句型：
① sth. be + adj. + enough (for sb.) to do
否定结构：sth. be not + adj. + enough (for sb.) to do
翻译：
The room is large enough for us to sleep in.

注意：to do 后面无需再加it。
to 后动词短语若有介词，介词不可省略
sth. be too + adj. + (for sb.) to do ?太。。。以至于不能。。。，表示否定意义
如何改写上述例句？
