We ,you and they should all help each other. 注：但要表示承认错误时，通常要把第一人称摆在前面。 It is I and Jack who are to blame. C）人称代词的指代问题C）人称代词的指代问题指代人的不定代词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： Nobody saw it,did he? 指代动物常用it 或they,有时也用he或they，以示亲切。如： Give the cat some food .He is hungry. 指代车、船、国家等，可用it，若表示感情色彩则用she.如： England has done what she promised to do. 代词we,you ,they有时可用于泛指一般人。如： They don’t allow us to smoke here.2)物质代词2)物质代词A）名词性物主代词(mine,yours,his,hers,its,ours,yours,theirs)与形容词性物主代词（my,your,his,her,its,our,their) 。形容词性物主代词在句中只能做定语；名词性物主代词则不能用作定语，但可以用作主语、宾语、表语、连用of作定语等。如： Our office is larger than yours.

Those who have not bought insurance are now regretting. B）this,that 用法区别B）this,that 用法区别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。 He was late again,and this (that）was what surprise me most. We all want to know this:Is it big enough？ C)that和those可用于替代前面提到过的名词，以避免重复。如： The population of Japan is much larger than that of Canada. D)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” 、“那么”。如： We can’t get there this (that) early. Is he always this (that) busy? 6)疑问代词6)疑问代词A）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： What is it you want me to do? Which is your room? Whose fault is it ? B）what和which的用法区别B）what和which的用法区别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： Which dictionaries do you like? What dictionaries do you like? 你喜欢哪本字典？你喜欢什么样的字典？ 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： What else do you need？ Which of the books is the cheapest? C)who,whom的用法区别C)who,whom的用法区别Whom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： Who(m) are you waiting for? For whom are you waiting? 7）连接代词 A）连接代词的形式与用法 疑问代词引导从句时为连接代词，连接代词主要引导主语从句，宾语从句和表语从句，同时连接代词在从句中用作主语、宾语、表语、定语等（但who和whom不能作名词前的定语。如： We don’t know who will come. Tell me whose wallet this is.

B）some和any的用法区别 Some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： Why not buy some fruit? “lend me some money.” “Didn’t your parents give you some?” Any有时也用于肯定句中，表示任何（一个）。如： Any dictionary will do. 注：按英语的习惯，any总是放在否定词not之后而不是之前，即not····any，所以类似以下否定句中不能改为any。如：注：按英语的习惯，any总是放在否定词not之后而不是之前，即not····any，所以类似以下否定句中不能改为any。如：Some students haven’t read it. 又当要否定整体中的部分时，用some不用any，如 I don’t know some of them. I don’t know any of them. C)复合不定代词的用法 修饰复合不定代词的定语应置于其后。如： I have nothing further to say. Did you notice anything unusal? 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： If anyone telephones,tell him(them)I’m out. 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： Everything is going well,isn’t it? 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：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：Every one of us want to see the film. D)指两者和三者或三者以上的不定代词，both，either，neither只能用于两者；all，any，none，every用于指代三者或三者以上；each可以用于两者，也可用于三者或三者以上。 The old man is blind in both eyes. All the students are sitting in the claaroom. 注：both，all修饰可数名词时，名词要用复数；either，neither，every只能修饰单数可数名词（不修饰复数名词）；any根据情况可修饰单数名词（可数或不可数）或复数名词。 E）不定代词与否定用法： 表示否定意义的不定代词，通常不再用于否定句。按英语习惯，表示非肯定意义的any，anyone，anything，anybody，either等总是放在否定词not之后，而不能置于否定词之前。如：I don’t know either of them.按英语习惯，表示非肯定意义的any，anyone，anything，anybody，either等总是放在否定词not之后，而不能置于否定词之前。如：I don’t know either of them.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。 F）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： Many students hate to do too much homework on Sundays. G)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. No one has the same bike to his.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：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：We each had a bedroom. She visits her parents every few days. Almost every student has seen the film. I)（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： Now I have little spare time. Can you give me a few minutes?注意以下习语的特殊意思：注意以下习语的特殊意思：what little 仅有的一点 a little =a little bit少许，少量的 not a little =very much 不少的，相当多的 not a few=quite a few=a good few许多，相当多 There’s a little bit of time left . It has given me not a little trouble. I spent what little time I had with her. J)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：Have another drink!

You are lucky to be alive. The twins look very much alike. 其他的表语形容词有：fine,ill,poorly,well,glad,pleased,sorry,upset,content.certain,sure,fond,ready等注：如语境需要，表语形容词可用于名词后作后置定语或宾语补足语，因为从某种意义上说，后置定语和宾语补足语在本质上相当于表语。如：注：如语境需要，表语形容词可用于名词后作后置定语或宾语补足语，因为从某种意义上说，后置定语和宾语补足语在本质上相当于表语。如：a girl afraid of dogs=a girl who is afraid of dogs B)定语形容词 即只能用在名词前作定语（或前置定语），而不是在名词后作定语，如main是定语形容词，可以说main things但不能说things main因为后置定语从本质上说相当于表语 2）多个形容词修饰名词时的排列顺序 描绘形容词—大小（长短高低）--形状—年龄（新旧）--颜色—国籍—材料—用途（类别）--名词，如： This is a nice small round new brown Chinese oak(橡木）writing desk。总体描述在前，具体描述在后；主观描述在前，客观描述在后。 普遍性描述在前，特殊性描述在后；短词在前，长词在后； 与所修饰的名词关系不紧密的在前，关系紧密的在后。 总体描述在前，具体描述在后；主观描述在前，客观描述在后。 普遍性描述在前，特殊性描述在后；短词在前，长词在后； 与所修饰的名词关系不紧密的在前，关系紧密的在后。 3)以-ly结尾的形容词 在通常情况下，形容词后加词尾-ly便构成副词，但friendly,lovely,lonely,likely,lively等后带ly，但它们却是形容词。如： 误：He treated us friendly. 正：He treated us in a friendly way. 注：有些以ly结尾的词既为形容词，也为副词，如daily,weekly,monthly,yearly,early等。如： We benefit from daily exercises. My father goes for a walk daily.4)形容词与介词的常见搭配4)形容词与介词的常见搭配A）be+形容词+about be angry about 为····生气 be anxious about 为····忧虑 be careful about当心 be certain about 确信···· be curious about 对···好奇 be disappointed 对····失望 be excited about 对···感到兴奋 be glad about对···感到高兴 be happy about 对···感到高兴 be hopeful about 对···抱希望 be mad about 对···入迷 be nervous about 为···感到不安 be particular about 对···特别讲究 be sad about 为···而难过 be serious about 对···认真 be sure about 对···有把握 be worried about为···担忧 B）be+形容词+at be bad at 不善于··· be clever at 擅长于····· be quick /slow at 在某方面敏捷或迟钝 be skilful at 在···方面熟练 C）be+形容词+forC）be+形容词+forbe anxious for 渴望 be bad for 对···有害 be famous for 因···闻名 be good for 对···有益 be grateful for 感谢 be ready for 为···准备好 be suitable for 对···合适 be thankful for 因···而感激 D）be+形容词+from be absent from 缺席 ，不在 be far from离···远 be free from 没有，免受 be safe from没有···的危险 E）be+形容词+in be concerned in 与···有关 be disappointed in 对某人失望 be esperienced in 有···的经验 be laking in缺乏 be successful in在···方面成功 be weak in在···方面较弱F）be+形容词+ofF）be+形容词+ofbe afraid of be ashamed of be aware of be fond of be full of be proud of be short of be shy of be sick of be tired of be worthy of G)be+形容词+to be close to be devoted to be equal to be familiar to 为某人所熟悉 be harmful to be important to be open to be polite to be similar to be used to be useful to be opposite to H）be+形容词+with be angry with be bored with be busy with be familiar with某人熟悉 be patient with对某人耐心 5）关于the+形容词5）关于the+形容词有的形容词（包括某些由分词转化来的形容词）可在其前加上定冠词the表示一类人或事。如： the rich the poor the blind the sick the old the young 这类用法往往具有复数意义。如: The rich are not always happier than the poor. 但若表示抽象意义，则被视为单数。如： The beautiful is not always the same as the good。 6）程度副词与频度副词 A）程度副词的用法特点：用于表示程度，常见的程度副词有fairly，rather，quite，very，much，too，greatful，highly，awfully，deeply，partly，perfectly，really等；程度副词主要用于修饰形容词和副词，有的还可以修饰比较级（如much，rather等）和最高级（如quite，much，almost等）。如： I’m quite certain of that。I’m quite certain of that。He speaks very highly of you。 注：quite有时可以修饰比较级，但只用于quite better这一表达。有的程度副词（如quite，rather，almost等）可修饰动词，但有的（如fairly，pretty，very等）则不能修饰动词。 B)频度副词的用法特点： 频度副词表示动作发生的次数，常见的频度副词有ever，never，rarely，seldom，once，constantly，frequently，usually，always等。频度副词通常位于实意动词之前，动词be、助动词、情态动词之后（有时为了强调，频度副词也可位于其之前）。如： The children are seldom ill。 Do you often watch television？ I’ve never been out so late before。注:有的频度副词可位于句末（尤其受very，only修饰时）。如：注:有的频度副词可位于句末（尤其受very，only修饰时）。如：I go there alone very seldom。 You should see your parents often。 注：含有否定意义的频度副词置于句首时，其后要用倒装语序。 Never have I read such books。 6）几个不重要的比较结构 A）as····as的用法特点: 其间只能接形容词与副词的原级，不能用比较级和最高级。有时该结构可受（not）nearly，almost，just，nothing like，exactly，not quite，half，two thirds，twice，threetimes，percent等词的修饰，注意这些修饰语必须置于第一个as之前，而不能置于其后。如： The dining-room is twice as big as the kitchen。 At best we can do only half as much as last year。 注：该结构中的形容词有时还可修饰另一名词，但这个名词应带有不定冠词（注意次序）。比较: She is as good a cook as her mother.=She is a cook as good as her mother.null
