【答案解析】

1.C.因为从can和句意可知，是指当前正在发生的事。句意是“如果你（象现在这样）持续地用一些无聊问题来妨碍我，我又怎能集中精力呢？”

2.C.因为意思是“我当时（昨天）怎么知道呢？”。

3.B.因为在时间状语从句中要用一般现在时代替一般将来时；若强调从句动作发生在主句动作之前时，用现在完成时代替将来完成时，本题属后一种情况。

4.D.从上文可知，已经将coffee溅在地毯上了，spilt已经在过去发生了，所以用一般过去时，wasn't。

5.B.因为these years是包括现在在内的，通常与现在完成时连用。

与现在完成时连用的标志：

It's the first[second，third穮]time that?的意思是

“这是第一次（第二次、第三次厖）做某事”。句首的it有时也可换成this，that等。如：

It's the second time I've come here.这是我第二次来这儿。

It's the first time that he has seen an elephant.这是他第一次见到大象。

This is the first time that I've heard her sing.这是我头一次听她唱歌。

若主句用一般过去时，则that从句通常用过去完成时。如：

It was the first time that I had ever driven a taxi.这是我第一次开出租车。一般过去时的用法：

think，mean等表示“想法”的动词的过去时有时能够表示过去未曾实现的想法，通常译为“本想”。如：

We thought to return early.我们本想早点回来的。

I meant to get up early，but forgot to set the alarm.

我本想要早起，但忘记了上闹钟。

I wanted to see the exhibition but the queue put me off.

我本想去看展览会，但是排队的人太多，使我不想看了。

注：更多的时候是用过去完成时表示以上用法。如：

I had meant to come，but something happened.我本想来，但有事就没有来。

I had intended to speak，but time did not permit.我本想发言，不过时间不允许。

现在实行时的用法：

现在实行时由“am/is/are+现在分词”构成，主要用于表示说话时或现阶段正在实行的动作或发生的情况。如：

I'm looking for a place to live.我正在找一个住处。

I'm thinking of studying medicine.我正在考虑学候。
