Unit 3 Body Parts and Feelings

单元语法聚焦三

动词have,has的用法

1.谓语动词have在一般现在时态的句子中有两种形式,即have和has。 have用于第一人称(I,we)、第二人称(you)以及第三人称复数(they或其他复数名词、并列短语等)之后,而has用于第三人称单数(he,she,it或单数可数名词或不可数名词)之后。

I__have many good friends.

我有很多好朋友。

They__have short hair.

他们留着短发。

The__boy__has two big blue eyes.

这个男孩有两个蓝色的大眼睛。

It__has four windows.

它有四扇窗户。

Our__English__teacher__has__ a red car.

我们的英语老师有一辆红色的小汽车。

2.其否定形式一般在have前面加don't;在has前面加doesn't,并把has改成have。

3.其一般疑问句由“Do/Does+主语+have+宾语+其他?”构成。当谓语动词是have时,若变一般疑问句,则在句首添加助动词do,其余不变;回答时用“Yes,主语+do.”或“No,主语+don't.”当谓语动词是has时, 若变一般疑问句, 则需要在句首加助动词does,

同时将has改为have,其余不变;回答时用“Yes,主语+does.”或“No,主语+doesn't.”

名词复数

1.规则名词的复数(详见课本附录)

2.单数与复数同形的名词

初中英语中单复数同形的名词主要有sheep(绵羊), fish(鱼), deer(鹿), Chinese(中国人), Japanese(日本人), Swiss(瑞士人)等。

3.不规则名词的复数

有的名词单数变复数时,没有一定的规则。如:

man→men 男人; woman→women 女人;

child→children 小孩; tooth→teeth 牙齿;

foot→feet 脚; mouse→mice 老鼠

注意:一些以­man, ­woman 结尾的合成词,变为复数时与 man, woman 的变化形式相同。如:

policeman→policemen 男警察

Englishwoman→Englishwomen 英国女性

另外,当man和woman用于名词前作定语时,若其后被修饰的名词为复数,man和woman也要用复数。如:women teachers 女教师
