考研英语试题语法难点精析--非谓语动词中的有关句型

（3）有关动词不定式句型
下面这些词组是不定式的习惯用法，只能用不定式形式。

can not help but do, can not but do, cannot choose but do, can do nothing but do, have no choice/alternative to do
When I consider how talented he is as a painter, I cannot help but believe that the public will appreciate his gift.

(4)there be的非谓语形式
there be非谓语形式可在句中作主语、的宾语、的状语和定语。(其中作宾语和状语在1991年和1994年测试过，定语见1996年题10。)

The students expected there to be more reviewing classes before the final exams．(作宾语如1991年题30)

1)作动词宾语时，通常用there to be结构，而不用there being。能这样用的及物动词为：expect，like，mean，intend，want，prefer，hate等，

如：
We don't want there to be any comrades lagging behind，我们不希望有任何同志掉队。
They hate there to be long queues everywhere.他们不愿意处处都要排长队。
We have no objection to there being a meeting here．我们并不反对在这里开会。
It isn't enough for there to be a frost tonight，so I can leave Jim's car out quite safely．(作状语)

2)作状语多用there being结构，但若置于介词之后，for用there to be整个介词短语作程度状语，其它多半用there being。

There being nobody else at hand, I had to do by myself．由于附近没有人，我只得独自干了。(原因状语)
It’s too early for there to be anybody up．太早了，还不会有人起床。(作程度状语)
There having been no rain for a long time，the ground was very dry．因为好长时间没下雨了，地面非常干燥。(原因状语)

3)作主语时两种结构都可以，但如是用for引导则要用there to be。

It is not uncommon for there to be problems of communication between old and young．老人与年青人之间存在着沟通问题是很常见的。
There being a kindergarten on campus is a great convenience to female teachers．幼儿园在校园内对女教师十分方便。

4)作定语。 There be结构作定语时，定语从句中谓语为there be，there之前的关系代词常常省略。

如：
This is the fastest train (that) there is to Nanking．这是到南京的最快一班车。
I must make full use of the time there is left to me and do as much as I can for the people．我要充分利用我剩下的岁月尽量为人民多做些事。
