二、重点知识点赏析

1：help with housework 帮助做家务

help v. 帮助 eg. Thanks for your advice, Mr. Clark. That helped me a lot last term.

n. 帮助 eg. I can’t make it without your help.

相关词组：

help sb.(to) do sth. 帮助某人做某事

eg. Could you please help me to take care of my puppy when I am away?

help sb with sth. 帮助某人（做）某事

eg. Tom is a good boy. He often helps his mom with housework.

Emily helped me ______ my English and I helped her ______ play the piano.

A. with, for B. learning, with C. with, to D. learn, with

【答案】C.

【解析】根据搭配 help ..with, help ..do..., help ...to do...，去掉 A，B, D 选项。

2：health n. 健康

eg. Nowadays, young people don’t have time to take care of their health. They are too busy.

be in good health=keep in good health=stay in good health 保持健康

Linda wants to keep in good health so she ______ twice a week.

A. eats junk food B. hang out C. go on a vacation D. plays tennis

【答案】D

【解析】首先单数第三人称剩下 A，D。既然是 keep in good health（保持健康），所以 plays tennis 是符合

的。而 eat junk food （吃垃圾食品）是不合题意的。

3：mind n. 头脑，心智

eg. Playing chess is good for your mind and body.

mind v. 介意

常用在句型 would you mind sth./ doing sth? 你介意（做）某事吗？

Would you mind moving your bike?

Would you mind not _______ ? There are some children here.

A. smoking B. smoke C. to smoke D. Smokeing

【答案】A。

【解析】本题考查 mind 的用法。介意做某事，mind doing sth. 介意不做某事 mind not doing sth.

另外，动词 smoke 的现在分词是 smoking。

4：although conj. 虽然，尽管，即使

eg. Although my grandma is 85-year-old, she is still in good health .

注意：在英语中，although 和 but（但是）不能连用。一个句子中只能用 although 或者 but。

______ my grandma is 85-year-old, _____ she is still in good health .

A. Although, / B. Although, but C. /, although D. But, /

【答案】A。

【解析】通过分析句意知道，两个分句是转折关系。前面用 although 或者中间用 but。

5：full adj. 满的；充满的

常用短语为 be full of...，充满...,满是.....；反义词是 empty，意为“空的”。

eg. The supermarket is full of people now. Christmas is coming.

The bottle was full ______ milk. Little Tom just drank it up.

A. with　　 B. in　　 C. of　　 D. at

【答案】C

【解析】本题考查 full 的用法。be full of 意为“充满……”，故用介词 of。

full adj. 吃饱的；过饱的，反义词是 hungry，饥饿的。

eg. ---- Are you hungry？

----- Nope. I just had a burger with Lisa.

6：She says it's good for my health. 她说它对我的健康有益。

1.本句是一个宾语从句。

She says 是主句，其后省略了 that，it's good for my health 是从句。

Eg. Tom says that he wants to be a movie star.

其中 be good for 对……有益

eg. Exercise is good for your health.

含有 good 的常见词组还有

① be good at 在……方面做得好；擅长……

Eg.He is good at learning languages.

②be good with 与……相处融洽

eg. Teachers should be good with their student.

7：I go to the movies maybe once a month.我可能一月去看电影一次。

may be 由情态动词 may 和 be 构成，意为

“可能是”，在句中作谓语。

这次可能你爸爸是对的。

______ Lin Tao wants to be a basketball player like Yaoming.

A. May be B. May C. Also D. Maybe

【答案】D.

【解析】本句已经有谓语 wants to be，所以答案是 Maybe 可能是，表推测。

least 是little 的最高级,意为最少的，最小的。

Eg. He has least money of all of us.
