对英语句子的认识

意义：英语的句式与中文的不同。我们在学习英语的时候要注意到这一点。有的同学在学习中对此没有足够的认识，常常受中文的干扰。在写作中表现出不能写出正确的句子。

I. 什么是句子？

　长的是句子，短的是词。×

　√ 无论字数多少，只要有主语和谓语(动词)，而且能表达完整的意义的一句话就是一个句子。

I am tired.

Pressing one’s palm together and resting one’s head on the back of one’s hand while closing the eyes as if sleeping means “I am tired.”(双手合拢，闭上眼，把头靠在手背上像睡觉的样子，意思是说“我累了。”)

　这两个句子都具备了主语和谓语。都是完整的句子。要记住：在英语中，一个句子必须且只能有一个谓语。

1. 省略主语的句子

Come in, please. (You)

Open the door.

Sit down.

Stand up.

What a day! (What a terrible day it is!)
