Answer 1

1.A.would not win 要是没有我英语老师的帮助，我也获得不了英语写作比赛一等奖。句子为含蓄条件句。
2.D.could not have finished 要是没有他们的帮助，我们也不能及时完成这个项目。句子为含蓄条件句。
3.B.should 这种印刷机质量很好，要是一年内坏了，我们将免费修理。句子为与将来事实相反假设的虚拟语气。
4.C.had been discovered 在高科技的帮助下，越来越多的物质在去年被发现。句子为与过去事实相反假设的虚拟语气。
5.D.hadn't seen 昨天Alan见到他朋友高兴吗？是的，很高兴。他好长时间没见他朋友了。句子为过去完成时。
6. B.has changed 他已经习惯的农村生活方式自从1992年以来已经发生了很大变化。句子为现在完成时。

2虚拟语气，同上，D
3句子为与将来事实相反假设的虚拟语气。B
4句子为与过去事实相反假设的虚拟语气。C
5 for a long time说明用完成时，然后，整个句子都是过去时，所以最终选择过去完成时。
