7. Match your subject to your pronoun and verb.
7. 主谓一致
This tip sounds obvious, but people often get it wrong. The number of the subject (whether it’s singular or plural) determines the number of the verb. Use a singular verb form–and pronoun– after nobody, someone, everybody, neither, everyone, each, either.
这个听起来容易做起来难。主语的单复数决定了谓语的单复数。在nobody, someone, everybody, neither, everyone, each other这样的主语后面使用单数形式的动词和代词。
8. Limit your use of adverbs
8. 减少副词的使用量
Use a strong verb instead of a weak verb and an adverb. Instead of writing “Sales grew quickly,” try “Sales accelerated.”
使用效果强烈的动词，代替效果弱的动词或副词。试着用"Sales accelerated" 代替"Sales grew quickly."
9. Know when to use “that” and “which.”
9. “that” 和“which"应当区分开来
“That” usually introduces essential information in what is called a “restrictive clause.” “Which” introduces extra information in a “nonrestrictive clause.” Here’s an example: “I’m interested in speaking with you about our new product, which has the potential to increase sales.” The second clause provides extra information, and it isn’t essential to the first clause. Therefore, “which” is correct. In a sentence such as “Computers are the only products that we sell,” the clause “that we sell” is essential to the meaning of the sentence, so the correct word is “that.” You can’t remove the “that” clause without changing the meaning of the sentence.
“that”通常适用于“限制定语从句”用于说明重要信息。"Which “用在”非限制性定语从句”中，来补充说明额外的信息。这里有一个例子:““I’m interested in speaking with you about our new product, which has the potential to increase sales.”第二个从句提供了额外的细信息，对于第一个从句来说它是次要的。因此,“which”是正确的。在这样的句子中：“Computers are the only products that we sell,”。“that we sell” 对于句子的意思来说是次要的。所以“that”是正确的。如果拿掉“that"后面的从句，就那么整句话的意思也是会被改变的。
10. Don’t confuse “affect” and “effect.”
10. 不要把“affect”和“effect”混淆
Affect is a verb that means “to influence.” “Effect” is a noun that means “result.” “The weather affects our ability to travel, and had a terrible effect on our flight to New York.”
影响是一个动词,意思是“影响”。“effect”是一个名词,意思是“结果”。“The weather affects our ability to travel, and had a terrible effect on our flight to New York.”
