1、表示举例,意为“例如,诸如此类的,像⋯⋯ 那样的”,相当于like 或for example。如:
There are few poets such as Keats and Shelly. 像济慈和雪莱这样的诗人现在很少了。
(1)这类结构既可表现为“名词+such as+例子”,也可表现为“ such+名词+as+例子”。如:
I enjoy songs such as this one.= I enjoy such songs as this one. 我喜欢像这首歌一样的歌。
(2)若后接动词,通常用动名词,有时也可用动词原形。如:
①Don't do anything silly such as marry him. 不要做什么蠢事,比如说去嫁给他。
②Magicians often perform tricks such as pulling a rabbit out of a hat. 魔术师常常变从帽子里抓出兔子的戏法。
(3)其后不可列出前面所提过的所有东西。如:
①I know three languages, such as Japanese and English. 我懂四种语言, 如日语、英语。(正确)
②I know three languages, such as Chinese, French, and English. 我懂三种语言,如汉语、法语和英语。(错误)
(4)such as后面常与etc.连用。如:
They planted many flowers, such as roses, sunflowers, etc. 他们种了许多种花,如玫
瑰花、向日葵等等。
2、表示“像⋯⋯ 这样的”,其中的as 用作关系代词,引导定语从句,此时不能把as用定语从句的关系代词that或which来替换。如:
(1)He is not such a fool as he looks. 他并不像他看起来那么傻。
(2)Such men as he (is) are rare now. 现在像他这样的人很少了。
3、表示“凡是⋯⋯ 的人(或事物) ”、“所有⋯⋯ 的人(事物) ”,其意相当于everything that, all those, those that (who)等。其中的such 为先行词, as 为关系代词。如:
(1)Take such (things) as you need. 你需要什么就拿什么。
(2)You may choose such as you prefer. 你可挑选自己想要的东西。
4、用于such ⋯ as to do sth,用来表示结果, 其中的such 为限定语, as to do sth 表示结果。如:
It was such a loud noise as to wake everybody in the house. 声音很大,屋里的所有
人都被吵醒了。
5、such as to do sth用来表示程度。如:
(1)Her illness was not such as to cause anxiety. 她的病不是很重,不必担心。
意思是说,她的病情还没有到达让人担心的程度。
(2)The pain in her foot wasn't such as to stop her walking. 她脚疼,但还不至于不能行走。
意思是说,她的脚疼还没有到达不让她走路的程度。
6、such as it is 是习惯用语, 表示让步, 意思是“尽管不怎么好”、尽管不一定正确”、“尽管没什么价值或重要性”。如:
(1)The food, such as it is, is plentiful. 食物尽管如此,但量还是很多的。
(2)You may use my bike, such as it is.你可以用的的自行车,尽管它就这个样子(尽管车不太好)。
