广州市七年级下册英语U5-语法专练

七年级下册英语U5 语法专练姓名_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 isnt 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？Its 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1、_ is the boy talking with your mother?

What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。我的你的他的/她的/它的我们的你们的他们的形容词性myyourhis/her/itsouryourtheir名词性mineyourshis/her/itsoursyourstheirs1） 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 doesnt like hers. 他喜欢我的钢笔。不喜欢她的。 There is a book. Its hers. 这有本书。是她的（书）。 （这里的hers=her book） 练习：一、 写出下列人称代词的形容词性物主代词和名词性物主代词形式I _ _ we _ _ you _ _she _ _ he _ _ it _ _they _ _二、用形容词性物主代词和名词性物主代词填空1.Iateall_sandwichesyesterday.( I )CanIhaveoneof_?

Canyouhelp_(he，him，his)?6.Wecantfindourbikes. Canyouhelp_(we，us，our，ours)?5.Theseare_(he，him，his)planes. Thewhiteonesare_(I，me，mine).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 doesnt work. I must buy a one.可以说：This pen doesnt 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1、 They only had expensive _, but i can only afford a cheap _.A. one, ones B. ones, one C. ones, ones D. one, one2、I bought a new pen yesterday.
