　　在英语中，有时为了避免结构上或内容上的重复，并使上下文紧密连接；有时因为语法的客观要求，句子中的一个或几个成分不需要表达出来，这种现象称为省略。省略有词法上的省略，也有句法上的省略，还有一种替代省略。在此，我们只研究句法的省略和替代省略。

语法点一 省略在简单句中的应用 　　1.祈使句的省略。在祈使句中通常省略主语。

　　(You) Do be careful of such things in the future.

　　今后一定要小心此类事情。

　　(You) Speak a little slower. I can't follow you.

　　你讲慢一点，我听不清楚。

　　2．在一些口语中可以省略某些句子成分。

　　(Is there) Anything else?

　　(还有)其他东西吗？

　　3．疑问句的答语省略。为避免重复而省略疑问句的答语，这也是常见的一种句式省略。

　　-Are you a student?

　　-Yes, I am (a student)．

　　--你是一名学生吗？

　　--是的，我是(一名学生)。

　　4．感叹句的省略。目的是突出感叹的部分。

　　What a beautiful girl (she is)!

　　(她是)多漂亮的女孩呀！
