问题描述:

choose the one that best completes the sentence
选择一个正确答案并解释为什么要选这个.
1.Is ____ you said really true?
A.what B.that C.which D.it
2.We have been told that under no circumstances ____ the telephone in the office for personal affairs.
A.may we use B.we may use C.we could use D.would we use

1.A. what 引导的定语从句不需要先行词
2.D. 首先否定词组放宾语从句的句首,宾语从句要倒装,所以排除B和C;其次tell,wish等动词引导的宾语从句一般用虚拟语气would do.

1.A
显然,此句考察了一个主语从句引导词问题,进而排除C,D;由于“say”是一个及物动词,故选“what”引导。
2.A
Under no circumstances 要求倒装。故只能在A,D中选。
而该主从句是现在完成时,所以不能选“would”。
以上仅为个人理解!

A
A

1.A 2.C

1.A 这句话是用is提问的一般疑问句.is what you said really true?你说的话真的是对的吗?what you said 作主语.
2.A Under no circumstances 要求倒装.当句首状语为否定词或带有否定意义的词语时,采用部分倒装.Under no circumstances“在任何情况下都不能”,没有过去意味,所以选A

1A
陈述句为what you said is true.what you said是这里的主语。在what you said中,what又是said的宾语。
2A
整句话是宾语从句。在从句中,under no circumstances置于句首时,要用倒装。而且从句是我们不能用公家的电话聊私事的意思。所以用MAY,可以。
