八年级上册英语unit3-4知识点汇总
Unit3重点讲解
1.“看起来”两不“像”:look like, look the same
As you can see, in some ways we look the same, and in some ways we look different.就像你看到的那样，在某些方面我们看起来一样，在某些方面我们看上去不同。
look like, look the same都可以表示“看起来像”之意。
(1)look like是由“不及物动词look+介词like”构成的动词词组，后面需接一个宾语。若表示“某人(物)十分相像”可用very much修饰。
Lily looks like your younger sister very much. 莉莉看上去很像你妹妹。
(2)look the same是一个固定词组，表示主语所包含的两个或两个以上的事物看起来一样，主语一定是复数，其动词look不可能出现looks形式。Look the same后面不再接其他成分，也不能用very much修饰。
Are you twins? You look the same. 你们是双胞胎吗?你们看起来一样。

A: same B: the same C: as D: like
(2)Although they are sisters, they dont _______ ________ ________(看起来一样).
2.all, both“都”不同
We both have black eyes...我们都有黑色的眼睛......(P33)
both 与all的用法相似。both强调两者都，而all则强调三者或三者以上都。

词条 区别 例句

形容词 “两者的，双方的” She wants both dictionaries.这两本书她都想要。
