Question

i would have gone to visit him in the hospital had it been at all possible,but i__fully occupied

. A were B had been C have been D was

Answer 1

Dwas

考查时态。I would have gone to visit him in the hospital had it been at all possible是含有虚拟语气的句子；but I_______ fully occupied the whole of last week.是真实的情况，要用陈述语气，再根据时间状语last week，可知要用一般过去时。所以选D。

一般过去时句法结构

1、肯定形式

主语＋动词过去式＋其它

例句：She came to help us in those days．

2、否定形态

主语＋didn't +谓语动词原形＋其它

在行为动词前加didn't，同时还原行为动词。

例句：I didn't know you like coffee.

3、一般疑问句

①Did+主语＋谓语动词原形＋其它

②Was/Were+主语＋表语

例句：Did you do homework?

Answer 2

选D。这个实质是很简单的，重点在于区别是否为虚拟，句意是“我本可以去医院看他的，但是我实在是太忙了”，根据句意很明显，“忙”是一个实际的状况而不是一个虚拟，所以用一般过去时表示一个过去的事实。

Answer 3

(i would havegone to visit him in the hospital) had it been at all posible,括号里面是主语，后面的it是形式宾语，指代前面的括号，后面but就是if not.虚拟语气，从句是过去式，主句用过去完成时。此题选D。
如果不是我上个星期的时间被占满了，我去医院看望他是完全有可能的

Answer 4

B

Answer 5

D was
