Ever experienced that moment after you press send and reread your email only to realize you've let some typos sneak in? Avoid that icky feeling from here on out by being hyper aware of some of the most common missteps. Whether you're applying for a job (don't forget to triple check that cover letter!) or sending emails to the boss, you don't want to look unprofessional by making mistakes that can easily be avoided. Here are some words you're bound to use in the working world and how to master them.

　　你有过这样的经历吗：在你按下发送以后重读了一下已发的邮件，才发现你的邮件里已经混入了不少错别字?从现在开始尽力避免那种糟糕的感觉吧，你可以把更多的注意力集中在那些最常见的错误上。不管你是要申请一份工作(别忘了再三检查你的求职信!)还是给老板发邮件，你都不希望因为一些很容易避免的错误而显得不专业。以下是一些你一定会在工作中用到的词以及你该如何掌握它们。

　　Misspellings to keep in mind

　　需要牢记心中的拼写错误

　　Amateur: The vowels at the end can get tricky, but pretend you are texting an Australian friend and say, "a mate u r."

　　Amateur：这个词末尾的元音颇具欺骗性，不过你可以想象你在和一个澳洲朋友发信息，“a mate u r”(你是个好伙计)。

　　Definitely: Just think of the word "definite" and add an -ly to the end. Never put an "A" in definitely.

　　Definitely：只要想到definite然后在后面加个ly就行了。千万不要在这个词里加上“A”。

　　Referred: Some people spell it refferred or refered, but remember it as a combination of two words: refer + red.

　　Reffered：有些人会把它拼成refferred或是refered，你要记住这个词是两个词的结合：refer和red。

　　Separate: Not spelled "seperate," separate will be easy to write out if you think of a grade-school trick — there is always "a rat" in the word.

　　Separate：不要按照发音而拼成“seperate”，如果你在拼写时想到这个词里始终有“a rat”，就很容易把它拼对了。

　　Occurrence: Ditch the singles and double up on the first two consonants for this one. Pretty soon it will become a regular occurrence.

　　Occurrence：记住这个词中的前两个辅音都需要双拼，这样你很快就能把它拼对了。

　　Common Mix-Ups

　　容易混淆的词

　　Affect vs effect: This one is tricky because just one letter can throw you off. Typically, "affect" is a verb and "effect" is a noun. If you can substitute a verb for affect, then you'll know that you're using it right (I was affected by the merger; I was surprised by the merger).

　　Affect和Effect：这两个词很容易混淆，因为只有一个字母的区别。通常来说，“affect”是一个动词而“effect”是一个名词。假如你换一个词来代替affect，你就会知道你是否把它用对了(I was affected by the merger; I was surprised by the merger 我对这次收购惊呆了)。

　　Loose vs. lose: Saying these words out loud will help you distinguish the two. "Loose" means not tight (The letter on my keyboard is loose). "Lose" is the opposite of win (We will lose this client if we don't pay him more attention).

　　Loose和Lose：大声喊出这两个词能帮助你把它们区别开来。“loose”的意思是不紧(The letter on my keyboard is loose 我键盘上的这个按键很松)。“lose”是win的反义词(We will lose this client if we don't pay him more attention 如果我们不多关注这位客户我们就会失去他)。

　　You're vs. your: Although you probably learned this one in grade school, it's easy to type one word when you really mean the other. "You're" is shorthand for "you are." The word "your" indicates possession (You're not going to believe how much they loved your presentation).

　　You're和Your：虽然你可能小学就学过这两个词了，但你还是很有可能会把它们拼错。“you're”是“you are”的缩写。而“your”是所有格。(You're not going to believe how much they loved your presentation 你不会相信他们有多喜欢你的演讲)。

　　Who vs. whom: Even a grammar wiz can get these two confused from time to time. But if you can switch the sentence around so that you use the word "him" as opposed to "he," then "whom" is the way to go. For example, instead of saying, "Sam is the guy whom we interviewed for the position," you could say "We interviewed him for the position." But in reversing the sentence "Sam is the guy who got the job," you would say, "He is the guy who got the job."
