是such as前加逗号,而for example 相反吗

是such as前加逗号,而for example 相反吗 such as 和for example哪个加逗号哪不加逗号? such as后可不可以只加一个例子 for example可不可以不加逗号 for example,such as 有什么区别?我是哪个要加逗号,加什么位置?谢谢 for that前一定要加逗号吗? 请问：such as 和for example的区别当“例如”讲时,请问such as 和for example的区别?以前我觉得for example后面加的是句子,而such as 后面加的是词.for example后面可以加单个的词吗? for example后可以不加逗号吗（后面加句子时）,并说明一下与such as的区别. Don’t read such books as are not worth reading.这是定语从句such...as的用法,are前不用加they吗? 等等前是否加逗号 such as后面能接介词吗?Matt trains in many ways such as by driving racetracks.这个句子是错在such as 后面不能接by 还有such as 前面的逗号是必须的嘛? There are many Chinese words such as 再见 and 这句句子里那几个中文词的引号是用英文的引号吗?词之间隔开是用顿号、英文的逗号还是不用加标点?小白求指教! such as,for example 哪个后面加,后,才加例子 either 前可以加逗号吗为什么有的句子是I don't like it,either .‘而有的句子是It is not the first one either 拜托请问such~as跟such as 和 the same as/that后面接的名词问题1.such~as 那样的~I have never seen such a man as he is.这句话为什麼有些人那个man可以用复数men?ex:Such men as he are rare now.是单复数都可以用麼?还 动词不定式前可否加逗号 such as和for example前面加不加逗号it has a population of around 23000000可以换成it has a population around 23000000吗? He often has sports.( ) ,football,basketball and ping-pong填For example 还是 Such as ,有逗号应该用前者,但前者不是举一例嘛? 请问for,example 和such as后面的动词要不要加ing,谢谢!
