    • 1.介词的功能介词是一种虚词,用来表达名词或相称于名词的其他词语句中其他词的关系,不能单独使用介词可与名词或相称于名词的其他词构成介词短语介词短语可在句中作定语,状语,表语和宾语补足语例如:The boy over there is John’s brother. (定语)The girl will be back in two hours. (状语)Our English teacher is from Australia. (表语)Help yourself to some fish. (宾语补足语)2.常用介词的用法辨析(1)表时间的介词1)at, in on表达时间点用at例如:at six o’clock, at noon, at midnight表达在某个世纪,某年,某月,某个季节以及上午,上午,下午,晚上时,用in例如:in the ninettenth century, in , in may, in winter, in the morning, in the afternoon等表达具体的某一天和某一天的上午,下午,晚上时,用on例如:on Monday, on July 1st, on Sunday morning等。

      2)since, after由since和after 引导的词组都可表达从过去某一点开始的时段,但since词组表达的时段始终延续到说话的时刻,因而往往要与目前完毕时连用而after词组所示的时段纯系过去,因而要与一般过去时连用例如:I haven’t heard from him since last summer.After five days the boy came back.3)in, afterin与将来时态连用时,表达“过多长时间后来”的意思,背面跟表达一段时间的词语After与将来时态连用时,背面只能跟表达时间点的词语After与过去时态连用时,背面才干跟表达一段时间的词语例如:He will be back in two months.He will arrive after four o’clock.He returned after a month.(2)表达地点的介词1)at, in, onat一般指小地方;in一般指大地方或某个范畴之内;on往往表达“在某个物体的表面”例如:He arrived in Shanghai yesterday.They arrived at a small village before dark.There is a big hole in the wall.The teacher put up a picture on the wall.2)over, above, onover, on和above都可表达“在……上面”,但具体含义不同。

      Over表达位置高于某物,在某物的正上方,其反义词是under above也表达位置高于某物,但不一定在正上方,其反义词是belowOn指两个物体表面接触,一种在另一的上面例如:There is a bridge over the river.We flew above the clouds.They put some flowers on the teacher’s desk.3)across, throughacross和through均可表达“从这一边到另一边”,但用法不同Across的含义与on有关,表达动作在某一物体的表面进行Throgh的含义与in有关,表达动作是在三维空间进行例如:The dog ran across the grass.The boy swam across the river.They walked through the forest.I pushed through the crowds.4) in front of, in the front ofin front of 表达“在某人或某物的前面”,在某个范畴以外;in the front of 表达“在……的前部”,在某个范畴以内。

      例如:There are some tall trees in front of the building.The teacher is sitting in the front of the classroom.3.介词的固定搭配介词往往同其她词类形成了固定搭配关系记住这种固定搭配关系,才干对的使用介词1)介词与动词的搭配listen to , laugh at, get to, look for wait for, hear from, turn on, turn off, worry about, think of, look after, spend…on…, 等2)介词与名词的搭配on time, in time, by bus, on foot, with pleasure, on one’s way to, in trouble, at breakfast, at the end of, in the end等3)介词与形容词的搭配be late for, be afraid of, be good at, be interested in, be angry with, be full of, be sorry for等。

      4.连词的功能用来连接词,短语,从句或句子的词叫连词连词是一种虚词,在句中不能单独使用连词可分为两类:并列连词和附属连词5.并列连词并列连词用来连接具有并列关系的词,短语或句子常用的并列连词有:(1)表并列关系的and, both…and, not only…but also, neither…nor等2)表选择关系的or, either…or等3)表转折关系的but, while等4)表因果关系的for, so等6.附属连词附属连词用来引导从句常用的附属连词有:(1)引导时间状语从句的after, before, when, while, as, until, till, since, as soon as等2)引导条件状语从句的if, unless等3)引导因素状语从句的because, as, since等4)引导目的状语从句的so that, in order that等5)引导让步状语从句的though, although, even if等6)引导成果状语从句的so that, so…that, such…that等7)引导比较状语从句的than, as…as等8)引导名词从句的that, if , whether等。

      7.常用连词的用法辨析(1)while, when, as这三个连词都可引导时间状语从句,但用法有所不同1)当某事正在进行的时候,又发生了另一件事While, when, as 都可用来引导表达“背景”的时间状语从句例如:As/When/While I was walking down the street I noticed a police car.2)当两个长动作同步进行的时候,最常用的是while例如:While mother was cooking lunch, I was doing my homework.3)当两个动作都表达发展变化的状况时,最常用的是as例如:As children get older, they become more and more interested in things around them.4)当两个短动作同步发生时,或表达“一边…一边…”时,最常用as例如:Just as he caught the fly, he gave a loud cry.She looked behind from time to time as she went5)当从句的动作先于主句的动作时,一般用when。

      例如:When he finished his work, he took a short rest.6)当从句是瞬间动作,主句是延续性动作时,一般用when例如:When John arrived I was cooking lunch.(2)as, because, since , for这四个词都可表因素,但用法有区别1)如果因素构成句子的最重要部分,一般用because因此,because引导的从句往往放在句末例如:I stayed at home because it rained.---Why aren’t you going?---Because I don’t want to.2)如果因素已被人们所知,或不如句子的其他部分重要,就用as或sinceSince比as稍微正式一点As和since 引导的从句一般放在句子的开头例如:As he wasn’t ready, we left without him.Since I have no money, I can’t buy any food.3)for用来补充阐明一种理由,因此,for引导的从句几乎可以放在括号里For引导的句子不放在句子的开头。

      例如:I decided to stop and have lunch----for I was feeling quite hungry.(3)if, whetherif和whether都可作“与否”讲,在引导宾与从句是一般可互换例如:I wonder whether (if) you still study in that school.I don’t know whether (if) he likes that film.在下列状况下,只能用whether,不能用if:1)引导主语从句时例如:Whether he will come to the party is unknown.2)引导表语从句时例如:The question is whether I can pass the exam.3)在不定式前例如:I haven’t made up my mind whether to go there or not.(4)so…that, such…that1)so…that中的so是个副词,其后只能跟形容词或副词,而such…that中的such是个形容词,后接名词或名词短语例如:I’m so tired that I can’t walk any farther.It was such a warm day that he went swimming.2)如果在名词之前有many, much, little, few时,用so,不用such。

      例如:He has so little education that he is unable to get a job.I have had so many falls that I am black and blue all over.(5)either…or…, neither…nor, not only…but also…这三个连词词组都可连接两个并列成分当它们连接两个并列主语时,谓语动词要随相邻的主语变化例如:Either you or he is wrong.Neither he nor his childr。
