I.e. and e.g. are both abbreviations for Latin terms. I.e. stands for id est and means roughly "that is." E.g. stands for exempli gratia, which means “for example.” "Great. Latin," you're probably thinking. "How am I supposed to remember that?”

I.e.和e.g.都是拉丁语缩写，i.e.代表id est，意为“也就是说，即”（that is），e.g.代表exempli gratia，意思是“举个例子”（for example）。你可能在想，“很好，拉丁语，可我怎么记得住啊？”

Forget about i.e. standing¹ for "that is" or whatever it really means in Latin. From now on, i.e., which starts with i, means “in other words,” and e.g., which starts with e, means “for example.” I = in other words. E= example.

不要去管i.e.的意思或者它的拉丁文全拼。从现在开始，i打头的i.e.代表in other words（也就是说），而e打头的e.g.代表for example（举例说明）。字母I= in other words，字母E= example。

Don't italicize i.e. and e.g.; even though they are abbreviations for Latin words, they've been used for so long that they're considered a standard part of the English language.

I.e.和e.g.不用斜体。虽然二者都是拉丁文缩写，但这种用法由来已久，已被视为英语中的一种标准用法。

Also, remember that they are abbreviations, so there is always a period after each letter.

另外，记住i.e.和e.g.都是缩写，所以每个字母后面都有点号。

A comma is usually used after i.e. and e.g.

I.e.和e.g.后面通常要加逗号。

1. The evaluation² noted³ that the employee had frequently exhibited irresponsible behavior (e.g., coming to work late, failing to complete projects).

评估报告指出，在雇员中存在许多不当行为（比如迟到，完不成工作）。

2. Writing instructors⁴ focus on a number of complex skills that require extensive practice (e.g., organization, clear expression, logical thinking).

写作教师强调那些需要大量练习的复杂技巧（比如结构，清晰的表达和逻辑性）。

3. The general rule is that if a number can be expressed in three words or fewer, it should be written out (e.g., two hundred seventy).

一般来说，如果一个数字能够用三个或三个以下单词表达出来，那么就应该将其拼写出来（比如two hundred seventy） 。

4. Use a comma to enclose (i.e., both before and after) the year in a month-day-year sequence.

“月－日－年”这样表达日期的形式，“年”应该用逗号分隔出来（即在其前后都使用逗号）。
