UKiset英语总结：as的用法全解析

as的用法比较特殊，意思比较灵活多变，句型搭配也比较广泛，更是UKiset英语考试中常考点。既能当介词，也可以作副词。今天课窝考试网小编就来总结一下as的用法吧！

一、介词as

1.好像

They entered the building disguised as cleaners.

他们伪装成清洁工进入了大楼。

2.作为；当作

I respect him as a writer and as a man.

我尊重他这位作家，也尊重他这个人。

二、副词as

他把诗中记得住的都背了出来。

2.像；如

他像往常一样无动于衷。

三、连词as

1.在……期间；当……时

随着年纪越来越大，他对一切都失去了兴趣，除了园艺。

2.因为

As he's been ill perhaps she;ll need some help.

3.尽管；虽然

我虽然还小，可是对想要从事的职业早已胸有成竹了。

4.以……的方式；按照

6.也一样（通常后接be或do+主语）

四、固定搭配

4.as it is 照现状看；看样子

五、辨析

1.when / while / as

三者都可以引导时间状语从句，翻译成“当……时”。大多数情况下都可以互换。when没有具体要求，时间点和时间段都可以；while只能用于时间段；as更多了一个“随着”的意思，可以表达“一边……一边……”。

When my mother came into the house, she found me lying there awake.

当妈妈走进家门时，发现我正在那睁着眼躺着。

While we were talking happily, the teacher came in.

我们正谈着开心，老师走了进来。

The little girl sang as she went.

这个小女孩边走边唱。

2.because / for / since / as

这几个都接从句，表示因为，具体区别可以参照之前的文章提到“因为”只知道because?盘点其他不熟悉的表达方式，助力写作

3.although / as

这两个都可以引导让步状语从句，但是as要进行倒装。

Although he is young, he knows a lot.

=Young as he is, he knows a lot.

虽然他很小，但是他知道的很多。

4.as for / as to

两者都可以表示“至于”。as for 更倾向于比较性，两者有一定的对比。有时可以包含说话人的一种轻蔑、冷淡、不屑、甚至是厌恶之感；as to更倾向于客观陈述，谈话的内容大家都有所了解。

You can have a bed; as for him, he'll have to sleep on the floor.

你可以有张床，至于他嘛，打地铺去吧。

As to your ability to overfulfil the target, I never had the slightest doubt.

关于你超额完成目标的能力，我从未怀疑过。
