一、两者的用法共同点
such as与for example均可用于表示举例，有时可互换。如：
Some sports, such as (=for example) motor racing, can be dangerous. 有些体育运动，比如赛车，有时是很危险的。
My wife likes social activities, such as (=for example) tennis and golf. 我妻子喜爱社交活动，如打网球和高尔夫球等。
二、两者的用法不同点
such as除表示举例外，还可表示诸如此类，意思是“像……这样的”“诸如……之类的”，此时不宜与for example互换（但可与表示诸如此类意思的like互换）。如：
Opportunities such as (=like) this did not come every day. 这样的机会不是天天都有的。
Avoid unhealthy foods such as (=like) hamburger and chips. 不要吃汉堡和薯条之类的不健康食品。
另外，such as有时可分开用，但for example不能分开用。如：
The disease attacks such animals as cats and dogs. 这种病只侵袭像猫狗一类的动物。(比较：The disease attacks animals such as cats and dogs.)
三、两者位置的不同点
such as用于举例时，总是跟在被说明的内容之后，不能独立成句，也不能用于句首或句末，其后也不能用逗号，但for example可以。如：
Each situation is different. For example, a man with a rich wife doesn't have to work. 情况各有不同，例如，娶了有钱妻子的男人就不必工作。
You make too many mistakes—lots of spelling mistakes, for example. 你的错误太多——比如，有好多拼法错误。
