Unit 2
重点讲解
1. full
full用作形容词，有多种含义：
①“忙的”，其同义词为busy。
②“满的”，其反义词为empty (空的)，常用于be full of
(充满……的)短语中。
③“吃饱了的”，其反义词为hungry。
【运用】写出划线部分的汉语意思
(1) Sorry, the hotel is full this evening. _________
(2) I’m full, so I don’t want to eat anything. _________
(3) Her life is full and she doesn’t have time to relax. _________
2. maybe
用作副词，意为“大概;或许;可能”，可与may be相互转换。如：Maybe you are right. = You may be right.
【链接】may be是由情态动词may加系动词be构成的，意为“也许是;可能是”。它位于句中，与后面的表语一起构成谓语部分。
【运用】
Ⅰ. 选词填空
1. ___________(Maybe / May be) you should often visit him.
2. Sara ___________(maybe / may be) in the museum now.
Ⅱ. 写出同义句

3. more than
①后接数词，表示“超过……;多于……”，同义词为over，反义词为less than(不到;少于)。
②后接名词，表示“不只是;不仅仅”。
【运用】汉译英
(1) 苏州有着2500多年的历史。

4. Only two percent of the students watch TV one to three times a week. Thirteen percent watch TV four to six times a week.
What percent of the students do not exercise at all?
①percent用作名词，意为“百分之……”。英语中百分数的表达形式为“基数词+percent”，percent无复数形式。
②当“百分数+of+the+名词”作主语时，谓语动词的单复数形式由of后面的名词的数来决定，即：of后面是复数可数名词时，谓语动词用复数形式;of后面是不可数名词或单数可数名词时，谓语动词用单数形式。
③再次使用“百分数+of+ the+名词”结构时，如果该名词在前面已经提到，则可省略“of+ the+名词”部分。
④对percent前面的基数词提问时用疑问词what。
【运用】选词填空
(1) 60 percent of the water in the river ___________(is / are) dirty.
(2) About 80 percent of the young people ___________(likes / like) popular music.
(3) ___________(What / How much) percent of the students always drink juice?
5. It is good to relax by using the Internet or watching game shows, but we think the best way to relax is through exercise.
①It is+形容词+(for sb.) to do sth.是英语中的常用句型，意为“(对某人来说)做某事……”。
②It is good to relax … 中的to relax在句中作真正的主语(it是形式主语)，而 … the best way to relax … 中的to relax在句中作定语。
③by和through用作介词时，都有“凭借;靠”的含义，后面接名词、代词或动词-ing形式。
【链接】through用作介词时还可意为“穿过”，强调从某一空间内穿过。
