複習需要講究正確的複習方法，抓住重點反覆練習，但也不是以偏概全的複習方式，下面是小編給大家帶來的八年級上冊英語unit3-4知識點彙總，希望能夠幫助到大家!
Unit3重點講解
1.“看起來”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“看起來像”之意。
(1)look like是由“不及物動詞look+介詞like”構成的動詞詞組，後面需接一個賓語。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是一個固定詞組，表示主語所包含的兩個或兩個以上的事物看起來一樣，主語一定是複數，其動詞look不可能出現looks形式。Look the same後面不再接其他成分，也不能用very much修飾。
Are you twins? You look the same. 你們是雙胞胎嗎?你們看起來一樣。
【練習】
(1)Lucy looks _______her mother.
A: same B: the same C: as D: like
(2)Although they are sisters, they dont _______ ________ ________(看起來一樣).
, 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強調兩者都，而all則強調三者或三者以上都。
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. 兩個學生都在這兒。
副詞 “兩者，兩者都”，位於行爲動詞之前，be動詞、助動詞、情態動詞之後。 They both went shopping last Sunday. 上週日他們倆都去購物了。
The twins are both students.這對雙胞胎都是學生。
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.這兩個答案都是錯的。
連詞 “......和....都”“既......又......”，用於連接兩個並列成分;連接兩個並列主語時，謂語動詞用複數。 He speak both English and French. 他既會說英語，也會說法語。
Both you and I were wrong.你和我都錯了。
