2015中考英语知识点总复习ago与before的用法区别区别1 两者均表示"以前",但ago以现在为基准,即指"现在以前",因此常与一般过去时连用;而before以过去某一时间为基准,指"在那时以前",因此常与过去完成时连用(且多用于宾语从句中).如:He left two years ago. 他是两年前离开的.She said he had left two year before. 她说他是两年前离开的.区别2 before也可泛指"以前",不与具体时间连用.此时可用于现在完成时或一般过去时.如:I have read the book before. 我以前读过这本书.He didn’t know that before. 他以前不知道此事.有关age 的几条用法说明说明1. 有关"年龄"(age)的常见表达:How old is he? / What’s his age?他多大年纪?He is ten (years old). / He is ten years of age. 他１０岁.I have a son (of) your age. / I have a son the same age as you.我有一个像你这样年纪的儿子.Their ages are 4.7 and 9. 你们的年龄是４岁.７岁和９岁.说明2. 表示"在……年龄时",英语常用"at the age of ＋数字"(有时也省略为"at age＋数字",或改用when 从句).如:He joined the army at the age of eighteen.He joined the army at age eighteen.He joined the army when he was eighteen (years old).他18岁时参了军说明3. "他年纪/ 老"不能直择为:His age is young / old. 可译为:He is young / old短语after all用法说明1. 表示"尽管怎样,但还是……",可译为"终究"."毕竟"(通常放在句末).如:I was right after all. 毕竟是我对.He tried for an hour and failed after all.他试了一个钟头,终究还是失败了.2. 表示"别忘了"(通常放在句首).如:I know he hasn’t finished the work but, after all, he’s very busy.我知道他还没做完工作,但别忘了他很忙.注:不要将after all 理解为"最后"."终于",而与finally 或at last 混淆.almost 与 nearly的用法异同一.相同之处两者均可表示"几乎""差不多",均可修饰不定代词.形容词.副词.动词.介词短语等,此时两者常可换用.如:I t’s almost [nearly] impossible. 那几乎是不可能的.(修饰形容词)He almost [nearly] always arrives late. 他差不多总是迟到.(修饰副词)He fell and almost [nearly] broke his leg. 他摔了一跤,险些摔断了腿.(修饰动词) Almost [Nearly] all the students passed the exam. 差不多所有的学生都通过了考试.(修饰不定代词)注意:修饰动词时,通常应放在行为动词之前,特殊动词之后(见上例);修饰形容词.副词.名词等时,通常应将其放在被修饰词语之前,否则会造成错误.如:◎他工作了几乎一整天.正:He worked almost all day.误:He almost worked all day.◎我们当中几乎每一个人都读过这本书.正:Almost every one of us read the book.误:Every one of us almost read the book.二.不同之处1. almost 可用于any 以及no, none, nobody, nothing, never 等否定词之前,但nearly 一般不这样用.如:Almost any man can do it. 几乎任何人都会做.Almost no one came to the party. 几乎没有人来参加晚会.I almost never see her. 我几乎从未见过她.但是,两者都可用在否定动词之前.如:( )He almost [nearly] didn’t catch the bus. 他差点没赶上公共汽车.2. nearly 前可用very, pretty, not 等词修饰,但almost 之前不能用这些词.如:It’s not nearly so difficult as you think. 这远不像你想象的那么难.The car is pretty nearly new. 这汽车几乎是全新的.注:not nearly 意为"远非",very [pretty] nearly 意为"几乎",都是习语.3. 有时almost 可表示十分相似(但又不完全相同),此时不用nearly.如:I almost wish I’d stayed at home. 我真有点后悔没在家里呆着.Our cat understands everything —he’s almost human. 我们这只猫什么都懂——快通人性了.含有add的四个有用短语1. add in 包括.如:Don’t forget to add me in. 别忘了把我也算上.Would you add in these items, please? 请你把这些条款包括进去好吗?2. add to 增加.如:This adds to our difficulties. 这增加了我们的困难.It adds to my pleasure to see you here today. 今天在这里见到你我格外高兴.3. add up(1) 加起来.如:You haven’t added the figures up right. 这些数字你没有加对.(2) 有意义,有道理(主要用于口语中,且主要用于否定句).如:His excuse just doesn’t add up. 他的借口完全站不住脚.What he said doesn’t add up. 他说的话自相矛盾.4. add up to(1) 加起来等于,总计.如:The figures add up to 500. 这些数字加起来等于500.The costs added up to 1000 dollars. 费用总计为1000美元.(2) 总起来看说明了.如:( )Your long answer just adds up to a refusal. 你的冗长回答简直等于拒绝.The evidence all adds up to a case of murder. 所有证据都说明这是一起谋杀案含有act的几个重要短语1. act as (临时)担任,充当,起……的作用.如:A trained dog can act as a guide to a blind person. 经过训练的狗可以担任盲人的向导. 表示担任独一无二的职务,其前通常不用冠词.如:He acted as manager in my absence. 我不在时他担任经理.I don’t understand their language; you’ll hav e to act asinterpreter. 我不懂他们的语言,你得当翻译了.2. act for 代理(某人职务),代为(处理某事).如:Please act for me during my absence. 我不在时请代理我处理事务.I acted for our captain while he was in hospital. 我们队长住院时由我代理他.3. act out (用手势和语言)表演出来.如:Let’s act out the story of the three bea rs once more. 让我们再把这三只熊的故事表演一次吧.4. act on (upon) 对……起作用,对……有效.如:The drug acts on the stomach. 这药对胃有效.Alcohol acts on the nervous system. 酒精对人的神经系统有影响.5. in the act (of) 当场,正在动作时.如:He was in the very act of starting. 他正准备动身.He was caught in the act (of reading my private letters). 他(在读我的私信时)被当场抓住angry的用法1. 表示"对某人生气",一般用介词with,有时也用at.He got angry with (或at) me. 他对我生气了.注:有人认为用with表示心中感到生气,而用at则表示怒气流露于外表.但总的说来还是用with的场合较多.2. 表示"对某事生气",一般用介词about 或at.如:She was very angry at what he said. 她对他说的话很生气.I was angry about missing the film. 没看上那部电影我很所恼.注:有人认为:at之后接某人之言行,about之后接某事,但种区别并不十分严格,两者常可混用.有关ago的几点用法说明1. ago在表示时间的"以前"这个意义时,应注意:(1) 只能与时间段状语连用,不能与时间点状语连用.(2) 只能放在时间名词之后,而不能置于其前.(3) 只能与过去时连用,不能与完成时连用.I met him three years ago. 我３年前见过他.注:若句中有助动词,有时也可用于完成时态.如;This would have been a couple of months ago. 这可能是几个月以前.2. 在"It was＋时间段＋ago"之后用that或when引导从句均可(构成强调句),但不能用since(若则since要去掉ago,并改was为is).如:He died twenty years ago.It was twenty years ago that (或when) he died.It is twenty years since he died. 他是20年前死的.after与behind用法小区别after 表示顺序的先后,behind 表示位置的前后.试比较:run behind sb. 在某人后面跑run after sb. 跑在某人之后(含有追上之意)Shut the door behind you. 关上你后面的门.Shut the door after you. 出入请随手关门.注:口语中的客套话"先生.你先请",右说成After you, 但不能说Behind you.accept与receive的用法区别1. receive 指"收到"."接到".表示一种被动的行为;而accept 指"接受",表示的是一种主动的行为,并伴随有一种满意或允诺的意味.试体会:He received the present, but he didn’t accept it. 他收到了礼物,但没有接受.2. 两者之后均可接名词或代词作宾语,但不可接不定式.如:He asked her to marry him and she accepted him. 他向她求婚,她同意了.但:不可说…she acce pted to marry him.3. 表示"接见"."接待"时,应用receive,不用accept .She was warmly received. 她受到热情接待.4. 表示"从……收到接爱……"时,两者之后均可接from.He received / accepted an invitation from his friend. 他收到/ 接受朋友的邀请. besides, except, but的用法区别1. 基本区别三者均可表示"除了",但besides 表示一种累加关系,意指"除了什么之外,还有…";而except 或but 则表示一种排除关系,意指"除了什么之外,不再有…":Mary knows Japanese besides French. 除法语外,玛丽还懂日语.She eats everything except [but] fish. 她什么都吃,但不包括鱼.但是,在否定句中,besides 也表示"除…外不再有… ",与but, except 同义:No one writes to me besides [except] you. 除你之外,没有人给我写信.2. 关于but 与except两者都可表示"除…外不再有…",但含义上略有差别:but侧重指意义的几乎完整性,而except 则侧重指后面除去的部分( ):All are here but one. 除一个人外大家都到了.All are here except one. 还有一个人没到.3. but用法的限制在现代英语中,but 的介词用法十分有限,通常用于no, no one, nobody, nothing, any, anyone, anything, every, everyone, everything, all, none, who, what等词语后: Nobody knew her name but me. 除我之外,没人知道她的名字.I have told this to no one but you. 除你之外,这事我没告诉任何人.Who but a fool would do such a thing?

你过去常到那儿去,是吗?另外,有时也可见到以下这样的否定式和疑问式,但不是很普通:Did you use(d) to be a teacher? 你过去是当老师的吗?They didn’t use(d) to live here. 他们过去没住在这儿.There used to be a cinema here, use(d)n’t there? 往日这里曾有家电影院,是吗?wait (for) 与 expect两者均含有"等"之意,但是有区别:wait for (等候)通常指在一个地方呆着,不采取任何行动,一直等到某事发生,它主要强调时间的流逝且含有耽误之意,有时暗示某人来得太晚或某事发生得太迟等;而expect(期待,预料)则指某事(可指好或不好的事)很可能会发生或到来,不强调时间的迟早,只说明一种心情.比较:他在校门口等他母亲.误:He was expecting his mother at the school gate.正:He was waiting for his mother at the school gate.我们在等乔治的来信.误:We are waiting for a letter from George.正:We are expecting [looking forward to] a letter from Goerge.那么我10 点整等你.误:Then I’ll wait for you at exactly ten o’clock.正:Then I’ll expect you at exactly ten o’clo ck.experiment的常用搭配用作名词(意为"实验")应注意以下几点:1. 表示"做实验",英语可用do (或make, carry out, perform) an experiment.2. 注意experiment 之后介词的选用.总的原则是(并不绝对):(1) 表示"用作或动物做实验",用介词on.如:do an experiment on him / the monkey用他/ 猴子做实验(2) 表示"做……实验",一般用介词in.如:make an experiment in physics / chemistry做物理化学实验(3) 表示"用……做实验"(用方法.材料等),一般用介词with.如:carry out experiments with new methods用新方法试验3. 表示"通过(用)实验",一般在experiment 之前用by.如:Scientists test out theories by experiment. 科学家用实验检验理论.注:experiment 还可用作动词,但一般只用作不及物动词,其后所接的介词与名词之后所接的介词大致相同,有时也有例外.如:make an experiment on electricity / to experiment on electricity 做电学实验enough用法详解1. 用作名词,是不可数名词.如:I’ve had enough. thank you. 我吃饱了,谢谢你.2. 用作形容词,通常与复数名词或不可数名词连用,且一般放在被修饰名词之前(在正式文体中也可置于其后).如:Are there enough seats for all?

It rained last night, for (不能用because) the ground is wet this morning. 昨晚下过雨,(你看)今天早上地面都是湿的.4. 其他(1) 汉语习惯上说"因为……所以",但英语却不能将because, since, as, for 与so(所以)连用.(2) 有时也有四者均可用的场合(如当要表示一个必然性推论时).如:He must have passed this way, because (或for) his footprints are here. / Since (或As) his foot-prints are here, he must have passed this way. 他走的一定是这条路,因为他的脚印还在这儿.beautiful, handsome, pretty & good-looking1. beautiful (美丽的),多用于女性,一般不用于男性.注意它是一个语气很强的词,着重指脸蛋迷人,体形匀称,比例完美,如:a beautiful girl (美女).另外,它也可用来指小孩或事物.如:a beautiful girl / picture 美丽的小姑娘.图片.2. handsome 多用于男性,意为"英俊的".如:a handsome young man (英俊的小伙),有时也用于女性(一般只用于成年女性,不用于少女),意为"体态健壮"或"端庄稳重".如:Do youdiscribe her as beautiful or handsome?
