C 你能为我说点什么(好话)么?
C whom这里代指的是前面的four men,但是因为做的是of这个介词的宾语,所以必须用往whom而不是who
Dwhat引导的句子是have的宾语,并不是在一定范围内选择所以不用which,且因为在we have here
这一从句中做宾语,所以不用that,只能用what
D到将来的一个时间点某个动作完成了用将来完成时,主语是building,只能是被动,所以D
B 可以理解是固定搭配吧
A 在人类患者身上测试之前要有五六年
再问: ②为什么不能选one of them?这句话是什么意思呢。。 ④不能选A将来时么?
再答: 因为这是一个句子。所以要用从句。一个句子的主句只能有一套主谓宾。如果是one of them was a doctor那么这就是一套完整的主谓宾,而且没有引导词不是从句,变成了一个完整的句子。中间就不能用逗号而必须用句号了。 By the end of next July ,by在这里是“到什么时间点之前”的意思,这个可以看成是一个完成时的标志,后面一般接各种完成时态。当然你也可以认为是两种都说得过去,但是从语境上看,用将来时态的完成时要更符合题意。将来完成时是指到将来的某一个时间点之前,一个动作已经完成. 如说 i will have had my breakfast at 8:00, so you can pick me up after that.
