逗号、分号、冒号是SAT写作中不可或缺的三大标点符号,它们对文章质量有很大影响,但往往不在考生备考范围内。下面小编带大家浏览一下这三大标点符号的使用规则,以期考生能尽快掌握,提高sat写作水平。
1. 逗号使用3规则:
1). 使用逗号来分开插入从句和短语;
例如:
Gordon, who is a writer by profession, bakes an excellent cheesecake.
2).用逗号分开系列成分。如果有2个以上相同成分,则应用逗号分开;
例如:
My recipe for buttermilk biscuits contains flour, soda and buttermilk.
3).在引导性分词或介词短语后使用逗号;
例如:
After the banquet, Harold and Martha went dancing.
4).利用逗号来分开连词连接的独立从句。
例如:
Susan’s old car has been belching blue smoke from the tailpipe for two weeks, but it has not broken down yet.
2.分号使用两大规则:
1) 使用分号而不是并列连词来连接两个含义紧密的独立从句;
例如:
Whooping cranes are an endangered species; they are unlikely to survive if we continue to pollute.
2)therefore、nevertheless和moreover等词连接的独立从句可用分号隔开。
(sat)例如:
The staff meeting has been postponed until next Thursday; therefore, I will be unable to get approval for my project until then.
3.冒号使用3大规则:
1).在正式的写作中,冒号的作用仅在于表明其后是对前面所述内容的详细说明、定义、解释或过去发生事情的概述。冒号之前一般是独立从句,并且通常情况下有as follows、the following、namely或like等提示短语。
例如:
正确:Your instructions are as follows: read the passage carefully, answer the questions on the last page, and turn over your answer sheet.
2).动词和直接宾语间不要放冒号。
例如:
错误:I want: a slice of pizza and a small green salad.
正确:This is what I want: A slice of pizza and a small green salad.
3).如果前后两句话有如上所述的紧密关系,即使没有上述表示这层关系的短语,也可使用冒号,并且在这种情况下,句号也可用。
例如:
正确:We were aghast: The “charming country inn” that had been advertised in such glowing terms proved to be a leaking cabin full of mosquitoes.
