8A Unit3-4知识点

八年级上册英语unit3-4知识点汇总（20xx人教版）unit3重点讲解1.“看起来”两不“像”:look like, look the sameas you can see, in some ways we look the same, andin 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。

假设表示“某人〔物〕非常相像”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，主语必须是复数，其动词look不行能出现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。

【练习】〔1〕lucy looks _______her mother.a: same b: the same c: as d: like〔2〕although they are sisters, they don't _______________ ________〔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的用法相像。

both强调两者都，而all那么强调三者或三者以上都。

both可用作形容词、代词和副词，其用法如下：词条区分例句代词“两者，双方，两人”，与of连用both of them are teachers.他们两都是教师。
