module 1 语法要点名词性物主代词表示所有关系的代词叫物主代词, 也可叫作代词所有格。可分为两种: 名词性物主代词和形容词性物主代词。请看下面表格:区别：1.形容词性物主代词起形容词的作用，用在名词前。例：（1）this is my book. 这是我的书。（2） we love our motherland. 我们热爱我们的祖国。2. 名词性物主代词起名词的作用。例：（1） look at the two pencils. the red one is yours and the blue one is mine. 看那两支铅笔，红色的是你的，蓝色的是我的。（2）he likes me. he doesnt like her. 他喜欢我。不喜欢她。（3）lucys hair is longer than lilys. 露西的头发比莉莉的更长。3. 注意：在使用名词性物主代词时，必须有特定的语言环境，也就是要省略的名词大家已经知道，已经提起过。例： its hers. 是她的。there is a book. its hers. 这有本书。是她的。只有上文提及了某个名词，才会知道名词性物主代词指代的事物。4.名词性物主代词=形容词性物主代词+名词为避免重复使用名词，有时可用“名词性物主代词”来代替“形容词性物主代词+名词”的形式。例：my bag is yellow, her bag is red, his bag is blue and your bag is pink.为避免重复使用bag，可写成my bag(形容词性) is yellow,hers(名词性=her bag) is red,his(名词性=his bag) is blue andyours(名词性=your bag) is pink.用法：1.物主代词既有表示所属的作用又有指代作用.例如：john had cut his finger; apparently there was a broken glass on his desk.约翰割破了手指，显而易见，他桌子上有个破玻璃杯。物主代词有形容词性(my， your等)和名词性(mine, yours等)两种，形容词性的物主代词属于限定词。名词性的物主代词在用法上相当于省略了中心名词的-s属格结构，例如：jacks cap意为the cap is jacks.his cap意为the cap is his.2.名词性物主代词的句法功能a. 作为主语，例如：may i use your pen? yours works better.我可以用一用你的钢笔吗? 你的笔比我的好用。b. 作宾语，例如：i love my motherland as much as you love yours.我爱我的祖国就像你爱你的祖国一样深。c. 作介词宾语，例如：you should interpret what i said in my sense of the word, not in yours.你应当按我所用的词义去解释我说的话，而不能按你自己的意义去解释。d. 作主语补语，例如：the life i have is yours. its yours. its yours.我的生命属于你，属于你，属于你。例句：this is my case.this case is mine.在这里的mine带有“我的(书)”的意思。this book belongs to me.用名词性物主代词，一般来说，人称代词都要有所变化，特别是i，不是mys”，要注意。3.名词性物主代词可以用在介词of的后面，相当于“of+名词所有格”。名词性物主代词可以单独使用比如：whose is this jacket?its mine（这里使用的是名词性物主代词）its my(这是错误的用法，形容词性物主代词不可以单独出现，只可以跟着句子出现，比如：this is my jacket(注意，它在名词前）。口诀有“名”则形“，无“名”则“名”。意思是：后面是名词的话，前面就要用练习题一、单项选择1. this is my book, that one is _. a. she b. her c. his2. _ pen is this? a. whose b. who c. whos3. this is not _bag. a. mine b. my c. he4. _ pencil is here, and _ is there. a. my, he b. mine, his c. my, his5. that is not _ jacket. a. yours b. hers c. his6. _ school is big, but _ is much bigger than _. a. yours, our, your b. your, our, your c. your, ours, yours 7. a friend of _ has gone to another school. a. me b. mine c. my8. i wonder whose bike it is. it might be my_. a. neighbours b. neighbours c. neighbours9. ive got a cold. i had to stay _ yesterday. a. at the doctors b. at the doctors c. at the doctor his10. my watch keeps good time. what about _? mine? oh, two minutes now. a. your b. hers c. yours二、用所给词的适当形式填空1. a: _ jacket is this? b: its _ (我的), sir.2. a: is this _ (他的)jacket? b: yes, its _.3. a: _ football is this? is it _ (你的)? b: no, its not _. its _ (她的). 4. a: are these _ (你们的) books?b: no, they arent. they are_ (他们的).三、完成句子a: is this _ (you) camera?b: no, its not _(i) camera. _ (i) is at home.a: whose camera is it?b: perhaps its helens. its _ (she).a: helen, is this camera _ (you)?c: yes, its _ (i) camera. thank yo
