广州市七年级下册英语U5 语法专练

一、疑问代词who 和whose

who与whose都是疑问代词，一般放在句首，用来构成特殊疑问句。

1、who的意思是“谁”，在句子中做主语，相当于名词、人称代词主格。后面不加名词。如： —Who is he ？ —He is John ． 他是谁？他是约翰。

—Who teaches your English？ —Miss Liu. 谁教你英语？ 刘老师。

当用who提问，不知道是谁和人的数量时，问句的谓语动词常用单数。如： Who isn't at school today？ 今天谁没到校？

2、whose的意思是“谁的”，可以单独使用，也可以和名词一起用，充当表语，定语等，相当于形容词。

1）提问部分作定语时，用“Whose ＋名词＋一般疑问句？”结构。如： Whose shirt is it？→It's my shirt． 这是谁的衬衫？→这是我的衬衫。

2）提问部分作表语时，用“Whose ＋一般疑问句？”结构。如： Whose is the shirt？→The shirt is mine． 这件衬衫是谁的？→这件衬衫是我的。 单项选择

二、物主代词 1、概述

表示所有关系的代词叫做物主代词(Possessive Pronouns)，也叫人称代词的所有格。物主代词分为形容词性物主代词和名词性物主代词两种。物主代词有人称和数的变化。第三人称单数的物主代词还有性别的变化。 形容词性 名词性 我的 my mine 你的 your yours 他的/她的/它的 his/her/its his/her/its 我们的 our ours 你们的 your yours 他们的 their theirs 1） 形容词性物主代词在句子中起形容词的作用，不能单独使用，必须在后面接名词 This is my book. 这是我的书。 We love our motherland. 我们热爱我们的祖国。

2）名词性物主代词在句子中与名词相似，起名词的作用，可单独使用。相当于“形容词性物主代词+名词”

Look at the two pencils. The red one is yours and the blue one is mine. 看那两支铅笔，红的是你的，蓝的是我的。 He likes my pen. He doesn’t like hers. 他喜欢我的钢笔。不喜欢她的。 There is a book. It's hers.

这有本书。是她的（书）。 （这里的hers=her book） 练习：

三、不定代词 one and ones

为了使表达简洁明了，我们常用one ， ones等代词来代替前面已经出现的名词。 1、 one通常用于代替表示泛指的单数名词。

I lost my pen. This is a new one. 我的钢笔丢了，这是一支新的。 Did you get a ticket? Yes, i managed to get one. 你弄到票了吗? 是的，我设法弄到了一张。 2、 ones用于代替泛指的复数名词。

Green apples often taste better than red ones.青苹果往往比红苹果好吃。

We can lend you plastic chairs or metal one.我们可以借给你塑料椅子或者金属椅子。 3、 注意：

1） 若one前面没有形容词修饰，其前面不能有不定冠词，但可以加another等。如：

不能说：This pen doesn’t work. I must buy a one.

可以说：This pen doesn’t work. I must buy (another) one. 2） 当one和ones紧跟在形容词最高级、序数词以及this, that, these, those, another 等限定词

之后时，通常可以省略。如：

Your picture is the most beautiful (one). 你的画是最漂亮的（一幅）。

The cakes are delicious. Would you like another (one).这些蛋糕味道真好。你要再来一个吗？ 练习： 单项选择
