八年級(jí)上冊(cè)英語(yǔ)unit3-4知識(shí)點(diǎn)匯總
Unit3重點(diǎn)講解
1.“看起來(lái)”兩不“像”:look like, look the same
As you can see, in some ways we look the same, and in some ways we look different.就像你看到的那樣，在某些方面我們看起來(lái)一樣，在某些方面我們看上去不同。
look like, look the same都可以表示“看起來(lái)像”之意。
(1)look like是由“不及物動(dòng)詞look+介詞like”構(gòu)成的動(dòng)詞詞組，后面需接一個(gè)賓語(yǔ)。若表示“某人(物)十分相像”可用very much修飾。
Lily looks like your younger sister very much. 莉莉看上去很像你妹妹。
(2)look the same是一個(gè)固定詞組，表示主語(yǔ)所包含的兩個(gè)或兩個(gè)以上的事物看起來(lái)一樣，主語(yǔ)一定是復(fù)數(shù)，其動(dòng)詞look不可能出現(xiàn)looks形式。Look the same后面不再接其他成分，也不能用very much修飾。
Are you twins? You look the same. 你們是雙胞胎嗎?你們看起來(lái)一樣。
【練習(xí)】
(1)Lucy looks _______her mother.
A: same B: the same C: as D: like
(2)Although they are sisters, they dont _______ ________ ________(看起來(lái)一樣).
2.all, both“都”不同
We both have black eyes...我們都有黑色的眼睛......(P33)
both 與all的用法相似。both強(qiáng)調(diào)兩者都，而all則強(qiáng)調(diào)三者或三者以上都。
both可用作形容詞、代詞和副詞，其用法如下：
詞條 區(qū)別 例句
代詞 “兩者，雙方，兩人”，與of連用 Both of them are teachers.他們兩都是老師。
Both of the students are here.=Both the students are here.
=The students are both here. 兩個(gè)學(xué)生都在這兒。
副詞 “兩者，兩者都”，位于行為動(dòng)詞之前，be動(dòng)詞、助動(dòng)詞、情態(tài)動(dòng)詞之后。 They both went shopping last Sunday. 上周日他們倆都去購(gòu)物了。
The twins are both students.這對(duì)雙胞胎都是學(xué)生。
形容詞 “兩者的，雙方的” She wants both dictionaries.這兩本書她都想要。
Both the answers are wrong.這兩個(gè)答案都是錯(cuò)的。
連詞 “......和....都”“既......又......”，用于連接兩個(gè)并列成分;連接兩個(gè)并列主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞用復(fù)數(shù)。 He speak both English and French. 他既會(huì)說(shuō)英語(yǔ)，也會(huì)說(shuō)法語(yǔ)。
Both you and I were wrong.你和我都錯(cuò)了。

3.“無(wú)論如何”however
However, we both enjoy going to parties. 不過(guò)，我們兩個(gè)都喜歡參加聚會(huì)。(P33)
