例句：The whole future of the company is at risk.
      这家公司的整个前途都处在危险之中。

3. They pull moisture from the leaves and keep plant tissues from getting water.

prevent...from,keep...from还有stop.....from 这三个句式的意义都是：阻止……做……或阻止某事的发生，而protect...from是表示保护……不受伤害

prevent...from 和stop……from 用在主动语态中from可以省略。
keep...from在表示此意时，from不可以省略。keep。。。doing 是使。。。处在。。。状态中的意思。
prevent...from,keep...from还有stop。。。from 这三个句式中from后面的动词与from前面的词构成动宾关系时，后面用动名词的被动形式。

We must prevent the water from being polluted.
我们必须防止水被污染。

What stopped him from coming here?
是什么阻止他来这里的呢？

The heavy rain kept us from coming on time.
大雨使我们没能及时到达。

4.So keep the garden watered.

watered做宾语补足语

能够充当宾补的还有宾语补足语的大致有：不定式，现在分词，过去分词，形容词，副词，介宾短语等。一般情况下，宾补通常紧跟在宾语之后。

比如：

I find learning English difficult.(difficult是形容词做宾补）

I saw the kite up and down. （up and down是副词做宾补）

Tom made the girl cry. (cry是省略不定式符号to的动词不定式）

*常跟复合宾语的动词有：call,name,make,think,find,leave,keep,nominate(任命),choose,elect(选举),define(定义),regard, see, recognize,treat, take,consider, look up, refer to, accept, acknowledge,describe,depict(描述),represent(表现出),declare(宣称),denounce, employ(雇佣), use, show, organize, express

当感官动词和使役动词，如：

see hear notice watch hear feel observe(感官动词)

make have let(使役动词)

接宾补时，不定式的符号to必须省略。

在help后,不定式可以带to,也可不带。
