1.Most of the earth's surface ________by water.
A.covers Bis covered C.are covered D.cover
为什么选B
2.When the work _______,the workers will have lunch.
A.will do B.will be done C.does D.is done
为什么选D
3.She _________some chotolates.
在这里need和needs不应该都可以嘛,为什么要用needs?

1.因为从翻译上“地球的大部分表面都被水覆盖”,我们可以得知这是被动语态,所以排除A、D.又因为surface 是不可数名词,所以要用单数的is covered
故选B.
2.这题也是,“当工作被做好了,工人就可以吃午饭了”而work是不可数名词.故用is done.
3.这里不可以用need,“她需要一些巧克力”但她是第三人称单数,所以必须用needs.另外,need的用法还有sb need to do sth
sth need to be done
sth need doing
完成了⊙－⊙
