The day on which she was born was 22
September, 1988. 英语介词和关联词 —试题与思路1.The doctor will be free ___.
A.in ten minutes B.10 minutes later
C.after 10 minutes D.10 minutes after
选A。in和将来时连用表示的是某段时间的终结点。after表示某个时间点之后的任一时间。later强调的是在某个时间点之后。
2.___ all the students, whom do you regard most highly?
A.Of B.About C.From D.In
选A。由most highly可知句首的短语是表示比较范围的状语。当给出所比较的人、事物所在的范围时,用in;给出所比较的人、事物的名称时用of。 英语介词和关联词 —试题与思路3.He was praised ___ his sense of duty.
A.about B.by C.for D.of
选C。句子要表达的是受表扬的原因,所以选for。
4.The key ___ success is hard work.
A.on B.to C.in D.for
选B。表示“进入、达到、对于”等含义的名词,需要和to连用。
5.Alice has a large collection of photos, ___ was taken in London.
A.none of them B.no one of which
C.all of which D.none of which 英语介词和关联词 —试题与思路选D。逗号后是一个定语从句,要有关系词来引导,可知A不可;从从句的单数动词was可知C不可;从no one 是表示人而且不可同of短语连用,可知其不可。
6.You are saying that everyone should be equal, and this is___ I disagree.
A.why B.where C.what D.how
选B。由disagree是不及物动词可知应选一连接副词来表达“在某处/某方面”之意,所以选B。
7.Mary can’t be admitted to a universi-ty next fall __ she can afford her further education.
英语介词和关联词 —试题与思路A.unless B.for C.as D.if
选A。从句意可知是有关条件的话题,所以表示原因的as和for均应排除;又由于主句是否定句,根据要标达的意思,应选否定条件连词unless。
8.__ encourages us greatly is ___ China has achieved great success in the Olympic Games.
A.What; what B.That; that
C.What; that D.That; what
选C。两个clause均为名词从句。第一个是主语从句,其中缺少主语,所以选连接代词what;第二个不缺少成分,所以用纯连词that引导。
