leave.v注：单独使用的人称代词通常用宾格。如：v“I want to leave.”“Me too.”v“Who did this?”“Me.”vB)人称代词的排列顺序。对于单数人称代词，其排列通常为“二、三、一”即you,he and me.而对于复数人称代词，则其排列通常为“一、二、三”即we,you and they.如：vYou,he and I are all senior students.vWe,you and they should all help each other.v注：但要表示承认错误时，通常要把第一人称摆在前面。vIt is I and Jack who are to blame.现在学习的是第13页，共44页C）人称代词的指代问题v指代人的不定代词anybody,everybody,nobody,anyone,someone,everyone,no one可用单数he,him或复数they,them;而指代事的不定代词something,nothing,anything,everything等则只能用单数it.如：vNobody saw it,did he?v指代动物常用it 或they,有时也用he或they，以示亲切。如：vGive the cat some food.He is

than yours.vYour parents are rich,and so are his.vB)形容词性物主代词与own连用，表示“自己的”或“亲自”。如：vThe machine is his own invention.vI saw it with my own eyes.vC)不要混淆its和its,前者为物主代词，后者为it is 的缩写现在学习的是第15页，共44页3）反身代词vA)反身代词主要用作同位语（加强被修饰词的语气，紧放在被修饰名词后，或句尾）和宾语。vYoud better go and see him yourself.vYou should learn to take care of yourself.v注：反身代词有时用作表语。如：vThe poor boy was

others,vone anothers.vIt was so dark that they couldt see each others faces.现在学习的是第17页，共44页5)指示代词vA）指示代词分单数（this,that)和复数（these，those)两种形式，在句中可作主语、宾语、表语、定语等，在具体使用时注意：v用作主语和定语时，可指人或物；用作宾语和表语时，只指物。如在This is my father.中this指人，作主语，但在Do you know this?中，this作宾语，且其代表的含义为一种情况，此句只能理解为“你知道这个情况吗?”而不能理解为“你认识这个人吗？”vthat和those可作定语从句的先行词，但this和these通常不能。另外，在作先行词时those可指人，但that不能。如：vWhat is that which you have just put in your bag?vThose who have not bought insurance are now regretting.现在学习的是第18页，共44页B）this,that 用法区别v当要回指上文提到的内容时，this,that均可，但若要指下文叙述的事情，通常要用this。vHe was late again,and this(that）was what surprise me most.vWe all want to know this:Is it big enough？vC)that和those可用于替代前面提到过的名词，以避免重复。如：vThe population of Japan is much larger than that of Canada.vD)this,that除用作代词外，有时可用作副词，用以修饰其他形容词或副词，其意相当于so，表示“这么”v、“那么”。如：vWe cant get there

this(that)busy?现在学习的是第19页，共44页6)疑问代词vA）主要用于构成特殊疑问句，其结构形式通常为“疑问代词+一般疑问句”。有的疑问代词指人，如who,whom,whose;有的疑问代词指人又指物，如which；在以上疑问代词中，who和whom只用作主语、宾语和表语，不用做定语；而what,which,whose则既可用作主语、宾语和表语，也可用作定语。如：vWhat is it you want me to do?vWhich is your room?vWhose fault is it?现在学习的是第20页，共44页B）what和which的用法区别v若选择的范围比较小或比较明确，则用which；若选择的范围比较大或不明确，则用 what，如：vWhich dictionaries do you like?vWhat dictionaries do you like?v你喜欢哪本字典？你喜欢什么样的字典？v注：表示不明确范围的what后可接else,表示其他的人或物，但不接表明确范围的of短语；而表示明确范围的which后一般不接else。但通常可接表明确范围的of短语，如：vWhat else do you need？vWhich of the books is the cheapest?现在学习的是第21页，共44页C)who,whom的用法区别vWhom是who的宾格形式，用作动词或介词的宾语，但在口语中用作宾语的whom通常可用who代替，不过在介词后只能用whom。如：vWho(m)are you waiting for?vFor whom are you

one,something,anything,everything,nothing)以及用作限定词的代词v（all,another,any,both,each,either,few,little,many,much,neither,none,other,some,no,every).vB）some和any的用法区别vSome用于肯定句中，any用于否定句、疑问句和条件句中。但是，在表示请求、邀请、征求意见、反问的句子中，通常要用some而不用any。如：vWhy not buy some fruit?v“lend me some money.”“Didnt your parents give you some?”vAny有时也用于肯定句中，表示任何（一个）。如：vAny dictionary will do.现在学习的是第24页，共44页注：按英语的习惯，any总是放在否定词not之后而不是之前，即notany，所以类似以下否定句中不能改为any。如：vSome students havent read it.v又当要否定整体中的部分时，用some不用any，如vI dont know some of them.vI dont know any of them.vC)复合不定代词的用法v修饰复合不定代词的定语应置于其后。如：vI have nothing further to say.vDid you notice anything unusal?v指人的复合不定代词作主语时，其谓语动词要用单数，而相应人称代词和物主代词却可用单数也可用复数，如：vIf anyone telephones,tell him(them)Im out.v指事的复合不定代词用作主语时，谓语动词只能用单数相应的人称代词也只能用it，而不能用they。如：vEverything is going well,isnt it?现在学习的是第25页，共44页anyone,everyone后通常不接of短语，但分开的any one，every one却可以接of短语，如：vEvery one of us want to see the

dont know either of them.v不定代词all，both，every等表示总括意义的不定代词与not连用时构成的是部分的否定，即not all=并非所有，not both=并非两者，not every=并非每一个。若要表示完全否定则需要改用none，neither，no one等。vF）many和much，两者都表示许多，many后接复数可数名词，much后接不可数名词。如：vMany students hate to do too much homework on Sundays.vG)none 与no one，none后可接of短语，既可指人也可指物，而no one后通常不接of短语，且只能指人；回答how many或how much的提问时，通常用，none，而在回答who的提问时，通常用no one或nobody；none作主语时，谓语动词单复数均可，而no one作主语时，谓语动词只能用单数，如：None of the telephones are(is)working.vNo one has the same bike to his.现在学习的是第27页，共44页H)every和each，every强调整体，each强调个体；every指三者或三者以上“每一个”，而each指两者的每一个；every只能用作定语，不可单独使用，而each可用作定语也可单独使用；every可受almost，nearly等副词的修饰，但each不能；every后可接“数词（或few）+复数名词”表示反复、重复的意思，但each不能。如：vWe each had a bedroom.vShe visits her parents every few days.vAlmost every student has seen the film.vI)（a）few与（a）little：（a）few后可接可数名词（复数），（a）little后接不可数名词；带有不定冠词的（a）few和（a）little表示肯定含义，不带不定冠词的few和little表示否定含义。如：vNow I have little spare time.vCan you give me a few minutes?现在学习的是第28页，共44页注意以下习语的特殊意思：vwhat little 仅有的一点 a little=a little bit少许，少量的vnot a little=very much 不少的，相当多的vnot a few=quite a few=a good few许多，相当多vTheres a little bit of time left.vIt has given me not a little trouble.vI spent what little time I had with her.vJ)other,the other,another与others，指单数时，若泛指用another，若特指用the other；指复数时，若泛指用other（后接复数名词）或others（后不接名词),若特指用the other（后接复数名词）或the others（后不接名词），具体的说有可以有以下的理解：一定范围内的两个，一个用one，另一个用the other；一定范围的三者，一个用one，另一个用one或another，第三个用the other；一定范围内多者，一个用one，一些用some，其余的用the others；泛指另一个用another，泛指的其他用others。如：现在学习的是第29页，共44页Have another
