引導(dǎo)定語從句。用于such as結(jié)構(gòu)，其中as為關(guān)系代詞；such as相當(dāng)于those who；such as 用作關(guān)系代詞，用法上相當(dāng)于that或which。

such as 的用法

表示舉例，such as 意為“例如，諸如此類的，像……那樣的”，相當(dāng)于like或for example。如：

There are few poets such as Keats and Shelly. 像濟(jì)慈和雪萊這樣的詩人現(xiàn)在很少了。

Adverbs are used to modify verbs, such as “quickly” in “she ran fast”. 副詞用來修飾動詞，例如“她跑得快”中的“快”。

Animals such as rabbits and deer continue to be active all winter，finding food wherever they can . 像兔和鹿這樣的動物整個冬天都是很活躍的，它們到處尋找食物。

用于此義時的幾點(diǎn)說明：

(1) 這類結(jié)構(gòu)既可表現(xiàn)為“名詞+such as+例子”，也可表現(xiàn)為“such+名詞+as+例子”。如：

I enjoy songs such as this one.= I enjoy such songs as this one. 我喜歡像這首歌一樣的歌。

(2) 若 such as 后接動詞，通常用動名詞，有時也可用動詞原形。如：

Don't do anything silly such as marry him. 不要做什么蠢事，比如說去嫁給他。

Magicians often perform tricks such as pulling a rabbit out of a hat. 魔術(shù)師常常變從帽子里抓出兔子的戲法。

(3) 不要按漢語意思將such as 用作such like。

(4) such as 后不可列出前面所提過的所有東西。如：

正：I know four languages, such as Japanese and English. 我懂四種語言，如日語、英語。

誤：I know four languages, such as Chinese, French, Japanese and English. 我懂四種語言，如漢語、法語、日語和英語。
