请大家给个解释和翻译
谢谢
如果只给答案不写原因的就免了

Answer 1

A. shoud not have done不该做某事（但实际应该做了）
needn`t have done不必要做（但实际上还是做了）
后面两个意思可以照着上面的理解，因为都是虚拟语气，所以表示的意思相反
D. must have been 那时一定是（PS：你那个句子后面是不是省略了一个冠词“a”啊）
would be 表示对将来的假设
would have been 本应该是（但实际不是）
must be 一定是（一般用在现在时）
C. shoud have done应该做某事（但实际没做）

这些基本都是考察虚拟语气的吧

Answer 5

3. A shouldn't have done=本不该
这句话的意思是，我本不该看那场电影的--看了现在老是做恶梦。
4. D must have been 是对过去事实肯定的推测
Jack描述的他那个拥有着坚强意志的父亲，很多年前一定是个勇敢的男孩~~
5. C should have done=本该做某事
这句话是讲，你本该昨天就完成的，因为那是最后期限了。

Answer 6

A, 这个你要翻译出来， 既然这个电影会让我做噩梦， 我本来不该看
B, 猜测他的父亲过去是个什么样的人，所以要用would have been
C,依然要翻译出来 因为昨天是deadline,所以你应该昨天就做完才对
