环球快讯:【百词斩】定语从句“as”用法特讲

这年头，人不可貌相，就连关系词也不例外。as的用法比that/which更复杂，我们一起来见见as的实力吧！

as 引导限定性定语从句时（没有逗号隔开），指与先行词相似的人或物。

1). 用于 the same...as...结构中，例如：

(资料图片仅供参考)

This is the same bag as I lost yesterday.

This is the same book as I bought last week．

This is the same material as is used in building the bridge．

2). 用于 such...as...结构中，例如：

He’s not such a fool as he looks.

I never heard such stories as he tells．

He was in such a hurry as I've never seen． 

3). 用于 so/as...as...结构中，例如：

I'm not so strong a man as I was．

You can buy as many books as you want in this store.

Some people believe that their cat understands as many words as a dog does．

注意：

1. the same A as B 与 the same A that B 的区别：

the same A as B：A和B同类

the same A that B：A=B

This is the same book as I lost last week.

这本书跟我上周丢的那本是一样的（两本一样的书）。  

This is the same book that I lost last week．

这是我上周丢的那本书。 （一本书）

She wore the same dress as her young sister wore.

她穿着和她妹妹一样的裙子（两条一样的裙子）。 

She wore the same dress that she wore at Mary’s wedding. 

她穿着她在Mary婚礼上穿过的那条裙子（一条裙子）。

2. 定语从句such...as...与结果状语从句such...that...的区别：

as在从句中作主、宾语；that在从句中不做成分。

He has such a good laptop as I want to buy. (as作buy的宾语）

He has such a good laptop that I want to buy one. (that不作成分)

She is such a good girl as everyone likes. (as作likes的宾语)

He is such a good boy that everyone likes him. (that不作成分)

最后，来份知识点小结：

1). 记住三大句式： the same...as...、 such...as... 、so/as...as...

2). 定语从句such...as...与结果状语从句such...that...的区别

好啦，有关as引导的限制性定语从句的知识点分享就到这里
