标题: such as 前面到底加不加逗号?

e.g.

怎么没有人回复呢?我也同问啊~你知道答案了吗?我在manhattan上看到个句子:Matt trains in many ways such as by driving on racetracks. 不知道这个句子错在 哪里。。。难道是such as 前面要加逗号?

such as,首先明确,是名词的修饰成分

名词的修饰成分有两种,必要的修饰成分和不必要的修饰成分;

加不加逗号就取决于such as...的内容是必要的,还是不必要的

The house painted red is mine; That house, painted red, is mine

这里要看,去掉修饰成分之后,被修饰的名词是否是明确的,可被辨别的:which house is mine?

第一个句子:the house. (but which one? not clear)  第二个句子:that house. (clear)

第一个句子,没有黑体部分,不能回答问题,即使the表示特指,但是特指是哪个?那么此时的painted red就是“必要的修饰成分”,它的作用就是使得the house is unique and distinguishable.

同理,第二个句子,那个房子,这里that本身就指明了是“那个”,而不是其他的,那么,此时,painted red就是不必要的,因为有没有这个修饰成分,the house can be distinguished.

the与that/this这个比较比较抽象,但是体会一下还是好理解的。

同样,具体到such as

They should clearly post emergency phone numbers, such as police, the FBI, the fire department.

Q: what numbers should they post? emergency phone numbers. clear. 这里,such as...是修饰不到整体的E phone numbers的,这里的emergency相当于形容词的作用

Matt enjoys intense activities, such as driving fast cars.(曼哈顿中习语部分一个正确的句子)
what activities does M enjoy? intense activities. clear. 所以这里such as前面加了逗号

Matt trains in many ways such as by driving on racetracks. 这句话,such as...作为必要的名词的修饰成分是一点错误没有的;in which ways does M train? many ways? not cleat enough,所以后面要加上必要的修饰成分。

这句话错误,是因为such as后,by doing的使用不正确。在R驾驶是M训练的一种方法,对吧?那么by driving is a way to train 还是 driving is a way to train?通过“驾驶”是一种训练方法?还是“驾驶”是一种训练方法?当然是后者,那个by是多余的。同样的,such as to do,to do不会以一种训练方法。
