不定式用法专讲
6. 不定式的完成式、进行式和完成进行式
不定式的一般形式所表示的动作，通常与主要谓语所表示的动作(状态)同时(或几乎同时)发生(a)，或是在它之后发生(b)：
a. Who heard him say that? 谁听见他说这话的?
Tell her we shall be delighted to come． 告诉她我们会很高兴来的。
We rejoiced to see her back． 我们看到她回来了都很高兴。
b. They invited us to go there this summer． 他们邀请我们今年夏天到那儿去。
She is waiting to hear your answer． 她在等着听你的答复。
They arranged to start early． 他们安排好早动身。
假如不定式所表示的动作，在谓语所表示的动作(状态)之前发生，这不定式就要用完成式，如：
I am glad to have seen your mother. (= I am glad I have seen your mother.) 我很高兴，见到了你的妈妈。
(比较：I am glad to see you. 看到你真高兴。)
不定式的完成式常用来：
1)构成复合谓语：
He is said to have written a new book about workers. (It is said that he has written a new book about workers.)
据说他又写了一本关于工的书。
The enemy was reported to have surrendered. (It was reported that the enemy had surrendered.)
据报道敌人投降了。
She seemed to have heard about it already. (It seemed that she had already heard about it.)
她似乎已听到这事了。

我碰巧有一次见过这本书。
She is not likely to have got our letter. (It is not likely that she has got our letter.)
她多半还没接到我们的信。
2)在某些作表语用的形容词后作状语：

(You are lucky that you have got tickets to the concert.) 你运气好弄到了音乐会的票。

对不起给你添了这么多麻烦。

3) 在某些动词后作宾语：

间或也可以作主语(a)，定语(b)或构成复合宾语(c)：

注1: 不定式的完成形式也有时和情态动词构成谓语：

How could you have read so much in such a short time?

这一用法在211中已经讨论了，这里就不再多谈。另外，to be有时可以和一不定式的完成形式构成谓语，表示一个想做而未做的事：
He was to have given the first talk, but he came late. 他本来第一个发言，但来晚了。
The plane was to have taken off at six, but something went wrong.
飞机本来在六点起飞的，但出了故障。
注2： 在不定式的完成形式后有时可以跟一个表示过去时间的状语：
He may have left last Monday. 他可能星期一就走了。
He is believed to have left last Monday. 据信他星期一已经走了
这是和现在完成时不同的。
如果主要谓语表示的动作(情况)发生时，不定式表示的动作正在进行，这时不定式就要用进行式。不定式的进行式主要可以用来：
1)构成复合谓语：
You are not supposed to be working. You haven't quite recovered yet.

间或也可以用作状语(a)，或主语(b)：
a. I am glad to be working with you. 和你在一道工作我很高兴。
How fortunate (I am) to be living here! 生活在这里多么幸福!
b. It feels wonderful to be working out of doors in such weather. 这样天气在外面劳动很舒服。

注: 不定式的进行式有时也可以表示一个反复发生的动作，这时带有感情色彩(关于这一点可参阅142)：

她总是这样工作，真不错。
I don't like you to be constantly arguing about trifles.
我不喜欢你们老为一些小事争论不休。
在上节所讲的许多结构中，如果不定式表示的不是正在进行的动作，而是在谓语所表示时间之前一直进行的动作，就需要用完成进行形式：

(It's said that they have been collecting folk songs in Yunnan.)
