回答：72.Before the end of the nineties, air pollutn __C____ a serious problem that endangers the health of the human race. a. will be become b. will become c. will have become d. will have been become 【十九世纪结束之前……为什么要用will和完成时呢？十九世纪不是早结束了么】 选C。理由：出题目所依据的文章是在90年代前写的，不是19世纪。84.My friend _____A_ here last week, but he couldn’t.  sthavecome med.hadtocome【求解释。。为什么上个月去那里要用这个时态而且还是be to？】 选A。理由：be to表示打算，因为事情过去，所以是过去的打算，所以用was to come,意思是：本打算来的，但没能成行。88.“What were you doing when Anna phoned you?” “I had just finished my work and ____D__ to take a bath.”  startc.havestartedd.wasstarting【不明白……开始不是一瞬间的动作么为什么也可以用过去进行时而且为什么要用啊。。and前后时态不是要统一吗】 选C。理由：这两个时态不矛盾。前面用过去完成时，因为动作在过去已经完成，在过去完成这个时间，正要开始做下一个动作，于是后面用了过去进行时。前后都是过去时，这是统一的。90.Each time you look at an object, you __B____ a picture.  etakingc.taked.havetaken【为什么用进行时啊…】 选B。理由：每一次你看着一个物体时，你都正在截取一幅图片（眼睛的功能）95.“Certainly,___D___ him about something else in any case, so it won’t be any bother.” a. I’ll see b. I see c. I can see d. I’ll be seeing 【我选A，这句话意思不太明白】 这里涉及到一般将来时和将来进行时的差别，将来进行时强调未来某个时间或时间段里将要发生的事情。这句话的背景应该是有人托说话人找人办事，说话人的意思：当然，不管怎样我要见他说点别的什么是，所以没什么麻烦的。98.He will come to call one you the moment he __B____ his work.  nished【the moment后的固定用法么？】 答案选B。the moment这里相当于as soon as，起连词的作用。102．--- May I go and play with Mike this afternoon, Mum? 　 --- No．You can't go out _B_____ your homework is being done．  ter【我选C】 如果选C，后面应该是until your homework has been done.所以我选B。由于你的作业正在做，所以不能出去。122．When I sat down, I found the book _____B___ on the table．  idopened【这个到底是放着还是躺着啊？这几个词的过去式什么的都好纠结】 lie lied lied lying 说谎lie lay lain  lying  躺着lay laid laid  laying 放置，产卵125．This is the same pen ____B____ I lost yesterday．It is a birthday present from my sister．  atC.whatD.when选A。the same---as 是固定搭配，as 引导定语从句。
