1.She was sorry that she had got no knife to...........
A.to cut B.cutting C.to cut it D.to cut it with
D(这题不明白)
she wanted to cut it with a knife, but she didn't have a knife to cut it with.
2.He did everything he could.........the old man.
A.to save B.save C.saving D.saved
A(could不是情态动词么,要加原型,为什么选A?)
He did everything (that )he could (do) to save the old man.
He did everything[此处省略的是everything的定语] to save the old man.
3.What he told us is very interesting,........?
A.isn't it B.isn't they C.can't they D.is it
A(为什么不选B?主语不是he么)
[What he told us此处是名词性从句作主语,作单数 ]is very interesting
4.Seldom..........his homework in the moring.
A.my brother does B.does my brother
C.my brother do D.does my brother do
D(为什么不选B?)
行为动词谓语在倒装时用助动词do+动词原形,此句中,用do+do
如下例同理:
I asked a question.
Did you ask a question?
He did his homework.
Did he do his homework?
5.............I saw was two men crossing the street.
A.What B.Whom C.Who D.That
A(为什么不选D)
what = the things that
that I saw作为从句不完整,saw 没有宾语,而主语从句必须结构完整。

1.首先排除B、C,对于A,给你举个例子吧:have something to eat,something是eat的宾语,knife总不能做cut的宾语吧。明白?
2.这里的“he could"是something的定语,这相当于一个定语从句,中间省掉了that,这里的to do做状语,……do everything to save……
3.这里的主语不是he,而是“what he told us”这个主语从句,所以反意疑问句里面用it代替!
4.以seldom这样的否定副词开头,后面应该接倒妆!
5.这里考得是做主语从句时that和what的区别,that接主语从句时后面接的句子是完整的,不缺任何成分,而这里“he saw"后面显然缺宾语!
希望我的解释你能满意!
