七．重点讲解

I have a small nose, but he has a big one.我有一个小鼻子，但是他有个大鼻子。（1）这里的have是实义动词，意为“拥有”，第三人称单数用has。现将其肯定式、否定式、一般疑问式及简略回答列表如下：

肯定式否定式一般疑问式简略回答

(I/We You They) have (I/We

You They)

don’t have

Do

(I/We

You have?

They)

Yes,

(I/We

You/they）do

No,（I，We.

You/They)

don’t

He/she/it has He/she/it

doesn’t have Does he/she/it

have…?

Yes, he/she/it

does.

No, he/she/it

doesn’t

【注意】在上述句式中do(don’t),does(doesn’t)为助动词，在句子中帮助构成一般疑问句及否定句作用，没有任何意义。当主语是第三人称单数时用does或doesn’t;当主语不是第三人称单数时用do或don’t.如：I have a nice cap.我有一顶漂亮的帽子。I don’t have a nice cap.我没有一顶漂亮的帽子。-Do you have a nice cap? 你有一顶漂亮的帽子吗？—Yes, I do /No, I don’t. 是的，我有。/不，我没有。

He has a pen.他有一支钢笔。He doesn’t have a pen.他没有一支钢笔。-Does he have a pen?他有一支钢笔吗？—Yes, he does./No, he doesn’t 是的，他有。不，他没有。

（2）此句型还可以转换成主语（物）+be动词+形容词。如：I have a small, but ha has a big one的同义句为：My nose is small, but his nose is big.我的鼻子小，但他的

鼻子大。

【即时演练】

1. 改为同义句。

（1）My face is round.______________________

（2）He has a good teacher.____________________

2. 单项选择。

Zhao Wei____________big eyes. She_______nice and cute.A have; is B has; is C is;has D are; is

(3)one 在这里作代词，用来替代已提及的或交谈者已知道的某个名词。如: You have a long ruler, but Ann has a short one.你有一把长尺子，但安有一把短尺子。【拓展】one的复数形式为ones,形容词性物主代词形式为one’s。如：We like blue cars. But they like white ones.我们喜欢蓝色的车。但他们喜欢白色的（车）。（ones 代替复数名词cars）

【链接】one 与it的区别

one与it 都可以代替上文出现过的名词，但it 往往指上文出现过的同一事物，而one则代指与前面事物同一类的事物，并不是同一个事物。如：I have a ruler. It is long. 我有一把尺子，它是长的。—Who has a ruler? 谁有尺子？—I have a one我有一把。

2.—Oh，I know. You are Kangkang. 哦，我知道了，你是康康。-Yes, you are right.是的，你是正确的。

(1)know V知道，了解，懂得，认识（2）right adj正确的在这里是形容词。You are right.相当于That’s right.你是正确的（你说的对）。

【拓展】right n.右边。反义词：left左边。
