for example
用来举例说明,由它引出介绍普遍概念的例子,使用范围要比such as自由。可以出现在句首、句末或有时可作为独立语,插在句中,不影响句子其他部分的语法关系。
例如, Cryptography operations, for example, decryption or signing, in a given period only involve the corresponding temporary secret key without further access to the helper.
同样for example ( e. g. )表示泛泛地举几个例子,并没有囊括所有的实例,其中就已经包含“等等”,如果再加etc.或and so on,就画蛇添足了。
如论文中出现的这句话是不当的:Writing instructors focus on a number of complex skills that require extensive practice (e. g. , organization, clear expression, logical thinking, etc. 正确的为e. g. , organization, clear expression, and logical thinking.
