虚拟语气在一些特殊词中的使用或含蓄条件句

1.wish后的宾语从句。

与现在愿望不一致，用主语十过去时，例如：

I wi。hIwere you.

与过去愿望不一致，用主语+had+过去分词，例如：Iwish I had visited the White House whenI was in the States与将来愿望不一致，用主语+would (could)+原形。

2.It's time句型：当lt's tine后用that从句时应该为主i吾+should+动词原形或主语十过去时，例如：It，s time thatyou went to school.或It's time that you should go to schooL

3- If only引起的感叹句相当于“How I wish+宾语从句”。

(l)If only he could come.他要能来就好了。

(2)If only I had known the answer.我要早知道答案就好了。

4.WOuld rather，as if(though)引导的从句也需使用虚拟语气，表示过去的情况用过去完成时，表示现在与将来的情况用过去时，例如：

(l)I'd rather you posted the letter right away.

(2)She loves the children as if they were hers.

5.含蓄虚拟条件句含蓄条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。但是这类隐含式虚拟条件句往往都可以转化为if引导的条件句。常用来表示含蓄虚拟条件的手段有：

(1)介词或介词短语。如but for，but that，without,in case of, under more favorable condition等。

(2)连词。如so that, unless, in case, supposing,lest, provided(倘若……)，for fear that(唯恐)，in orderthat, on condition that, if only(要是……就好了)等。

注意：lest, for fear that和in case引起的从句中谓语动词多用should+动词原形，但也可以不用虚拟语气，而用动词的陈述语气形式。例如：The foreign teacher spokeslowly in case we misunderstood him这位外籍教师说得很慢以免我们误解。

(3)通过上下文及内在含义，句中往往有but,otherwise, unfortunately等类似转折词。

without, but. but for, otherwise引起的短语或句子常暗含着含蓄条件。例如：

①Without you,1 would never know him

②But for your oooperation, we wouldn't have done it

③But that she was afraid, she would have said no. .

④i would be most glad to help you, butI am busy now.

⑤I would have come to the party yesterday, but ljwas working.

⑥I am busy now, otherwise l would do you the favor!

解释：

1. 主语从句能用it作形式上的主语。常以it作形式主语的句型有：

A. It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。如：

It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。

It is probable that he told her everything. 很可能他把一切都告诉她了。

B. It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。如：

It’s a pity that we can’t go. 很遗憾我们不能去。

It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。

C. It+be+过去分词(said, reported, thought, expected, decided, announced, arranged, etc.)+that从句。如：

It is said that Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。

It is reported that China has sent another man-made earth satellite into orbit.

据报道中国又成功地发射了一颗人造地球卫星。

D. It+seem, happen等不及物动词及短语+that从句。如：

It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。

It happened that I was out that day. 碰巧我那天外出了。

E. It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。如：

It doesn’t matter whether she will come or not. 她是否来这无关紧要。

It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。

F. 当that引导的主语从句出现在疑问句中时，要以it作形式主语，而把主语从句后置。如：

Is it true that the scientist will give us a lecture next week? 下周那位科学家将给我们作报告是真的吗?

Does it matter much that they will not come tomorrow? 他们明天不来很要紧吗?

G. 当主语从句出现在感叹句中时，要以it作形式主语，而把主语从句后置。如：

How strange it is that the children are so quiet! 孩子们这么安静真奇怪!

2.注意连接代词whoever, whatever, whichever等引导主语从句的含义

Whoever comes will be welcome. (whoever=the person who) 来的人将受到欢迎。

Whatever he did was right. (whatever=the thing that) 他所做的事情是正确的。

Whichever of you comes in will receive a prize. (whichever=anyone of you who) 你们当中不论哪个进来将会得到奖
