4.英语中没有顿号“、”。要表示句中较短的并列词语之间的停顿，汉语习惯用顿号，而英语只能用逗号；汉语中连词“和”、“及”等之前不可用顿号，而英语中连接一系列并列项目的“and”或“or”之前往往可以用逗号。 5.使用所有格符号时，要注意放在正确的位置上，以免引起意义上的混淆。如my sister’s book不能写成my sisters’ book。
6.汉语中直接引语前的“某某说”等词语之后一律用冒号。而英语中既可用逗号，也可用冒号。当“某某说”等词语在直接引语后时，汉语的引语末尾用句号，而英语一般用逗号。如句子 “It's none of your business,” the young men said rudely．其汉语译文是：“这不管你的事。”年轻人粗暴地说。
7.问号用在直接疑问句之后。间接疑问句是作为一个从句来处理的，不能用问号。如 I didn't know what he meant by that． 8.英语中没有书名号《 》，书名一般用引号。如：Yesterday she saw an English film “Gone with the Wind”。
9.文章每行的起首除了引号和括号外，不应书写其它标点，引号和括号最好标在同一行中。句子较长时，可以分行标号，但千万不能顾头不顾尾。
