Answer 1

1 选C.
解析：对过去肯定的推断用 must have done,be busy doing 忙于,故选C.
2 选A.
解析：根据 By the time 要用完成时态.
3选D.
解析：It is first/second time that + 现在完成时.这里前面是过去时态,后面要用过去完成时态.
4 选B.
解析：”我“想法应该是在看比赛之前,所以用过去时态.
5 选D.
解析：think of...as...把...看作,让我们把句子还原：We must not think our modern civilization as—— in a short period of time.填空的地方创造出来,肯定在我们想之前,故用完成时态.
祝开心~!
