总结不定式中可以省略to的情形讲解（五）

6、不定式作表语与 to 的省略
当不定式用作表语的时候,其中的 to 原则上是不能省略的。如:
His aim is to make a million dollars in ten years. 他的目标是十年挣一百万。
This wall made of stone was to keep the cattle out。这堵墙为的是不让牲畜进来。
但有一种例外,那就是当主语部分有动词do的某种形式时,用作表语的不定式可以省略to。如:
All I did was (to) touch the vase, and it broke all of a sudden. 我只不过碰了一下窗户,它突然就碎了。
7、并列不定式与to的省略
当两个或多个作用相同的不定式并列时,通常只需在第一个不定式前用 to,其余不定式前的 to 可以省略。如:
I’d like to go to sleep and(to)have a good rest。我想躺下休息了。
Will you go to the America or (to)the Africa? 你要去美洲还是非洲啊?
但是,如果两者有对比关系,则后面不定式前的to不可省略。如:
To try and fail is better than not to try at all. 尝试而失败总比不尝试好。
8、固定搭配与to的省略
1. let类固定搭配:let fall (无意中说出),let fly(发射、攻击),let go (放开),let slip (放走),live and let live (自己活也让别人活)等。如:
She let slip an opportunity to study abroad. 她错过了出国留学的机会。
He arranged all and then let fly. 他安排好了之后便开了枪。
I got to know what was going around from a few words she let fall. 我从她说的几句话中猜出发生什么事了。
2. make类搭配:make believe (假装),make do (凑合着用)等。如:
The girls made believe (that) they were angles.女孩子们假扮成天使。
We were in a hurry so we had to make do with a quick snack. 我们时间很紧,只好胡乱吃了顿小吃。
