Answer 1

下面你有几处你打字错误，印刷的试卷模糊了点，你看不清楚吧，不过也不至于连这简单的单词也不认得？！
1。That day he ____his clothes before he came to see me.
B washed
他在来我这里之前洗了衣服。。。时间上有“过去的过去”意思。貌似要用过去完成时态，或者过去进行时。A现在完成时，排除，D被动肯定也错。 C过去完成进行时，强调一个持续了很长的动作，直到某个时间仍在继续。。。而本句子明显只是说他看我之前洗了衣服这件事，并无强调直到来看我还在洗衣服....答案C贴切.........

2 "have you seen the art exhibition？"no,___there
A it was not been held
回答：那个时间没有举办展会。。。主语要用it贴切，但it要用被动，A属被动，其他不是

3 Since l____you last.l___very luck in everingthing
C saw/have been
since引导从句，是现在完成时态的标志。。。紧接since的从句表示叙事（过去的事情）要用过去时态saw， 主句用完成时have done.....

4 When l ____across a new words.L look it up in the dictionary.
C come
当....怎么样，表示普通叙事，前后动词时态一致......

5 5We____successes so far,but the successes ___in one day.
D have won/weren't won
so far 是完成时的暗示，从句用完成时have won. 后半句叙事，成功不是一蹴而就的，本应该用普通的被动 is not won，但由于前半句是完成时，后面时间上要一致。。。就要用过去时weren't won..............haven't been won过去完成时跟in one day意义冲突，不能选........
