幾道英語選擇題(請說明理由)

A.does do B.do does C.do do D.does did
2.we should spare no efforts to stop pollution ___happily.

3._____for the dog.You'd better ___it .
A.watch out ; get away from
B.take care ; get away from
C.be careful ; get out of

解答:

1 A
在動詞前加do表示強調,因爲what he eats是他吃的東西,是單數,所以用does,在表示強調的詞後面的動詞用原型,所以用does後用do,do harm to是固定詞組,表示對.有危害
2 A
stop...from 固定詞組搭配,意思是讓.遠離.
這句話的意思是我們應該不遺餘力的讓汙染遠離我們的快樂生活
3 A
watch out 是當心,小心的意思,get away from是指遠離
整句話意思是,當心狗,最好遠離它.
take care 是照顧的意思,後面一般跟of
be careful是小心,當心的意思,但是後面的get out of是指下車或者從.出來,不符合句意
