1、介词 连词考点集汇 讲解和训练 附答案 高一英语初高中衔接专题六专题六：介词、连词考点集汇，讲解和训练1. 介词的功能介词是一种虚词，用来表示名词或相当于名词的其它词语句中其它词的关系，不能单独使用。介词可与名词或相当于名词的其它词构成介词短语。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 Johns 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
2、. (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表示时间点用at。例如：at six oclock, at noon, at midnight。表示在某个世纪，某年，某月，某个季节以及早晨，上午，下午，晚上时，用in。例如：in the ninettenth century, in 2002, in may, in winter, in the morning, in the afternoon等。表示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,
3、 after由since和after 引导的词组都可表示从过去某一点开始的时段，但since词组表示的时段一直延续到说话的时刻，因而往往要与现在完成时连用。而after词组所表示的时段纯系过去，因而要与一般过去时连用。例如：I havent heard from him since last summer.After five days the boy came back.3） in, afterin与将来时态连用时，表示“过多长时间以后”的意思，后面跟表示一段时间的词语。After与将来时态连用时，后面只能跟表示时间点的词语。After与过去时态连用时，后面才能跟表示一段时间的词语。例如：H
4、e will be back in two months.He will arrive after four oclock.He returned after a month.（2）表示地点的介词1）at, in, onat一般指小地方；in一般指大地方或某个范围之内；on往往表示“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
5、wall.2） over, above, onover, on和above都可表示“在上面”，但具体含义不同。Over表示位置高于某物，在某物的正上方，其反义词是under。 above也表示位置高于某物，但不一定在正上方，其反义词是below。On指两个物体表面接触，一个在另一的上面。例如：There is a bridge over the river.We flew above the clouds. They put some flowers on the teachers desk.3） across, throughacross和through均可表示“从这一边到另一边”，但用法不
6、同。Across的含义与on有关，表示动作在某一物体的表面进行。Throgh的含义与in有关，表示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 表示“在某人或某物的前面”，在某个范围以外；in the front of 表示“在的前部”，在某个范围以内。例如：There are some t
7、all trees in front of the building.The teacher is sitting in the front of the classroom.3. 介词的固定搭配 介词往往同其他词类形成了固定搭配关系。记住这种固定搭配关系，才能正确使用介词。（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, spendon, 等。（2）介词与名词的搭配on time, in tim
8、e, by bus, on foot, with pleasure, on ones 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：并列连词和从属连词。5. 并列连词并列连词用来连接具有并列关系的
9、词，短语或句子。常见的并列连词有：(1)表并列关系的and, bothand, not onlybut also, neithernor等。(2)表选择关系的or, eitheror等。(3)表转折关系的but, while等。(4)表因果关系的for, so等。6. 从属连词从属连词用来引导从句。常见的从属连词有：(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)引导原因状语从句的because, as, since等。(4)引导目的状语
10、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)引导结果状语从句的so that, sothat, suchthat等。(7)引导比较状语从句的than, asas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 都可用来引导表示“背景”的时间状语从句。例如：As/When/While I was walk
11、ing down the street I noticed a police car.2) 当两个长动作同时进行的时候，最常用的是while。例如：While mother was cooking lunch, I was doing my homework.3) 当两个动作都表示发展变化的情况时，最常用的是as。例如：As children get older, they become more and more interested in things around them.4) 当两个短动作同时发生时，或表示“一边一边”时，最常用as。例如：Just as he caught the
12、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，通常用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，通常用when。例如：When John arrived I was cooking lunch.（2）as, because, since , for这四个词都可表原因，但用法有区别。1) 如果原因构成句子的最主要部分，一般用because。因此，becau
13、se引导的从句往往放在句末。例如：I stayed at home because it rained.-Why arent you going?-Because I dont want to.2) 如果原因已被人们所知，或不如句子的其它部分重要，就用as或since。Since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 wasnt ready, we left without him.Since I have no money, I cant buy any food.3) for用来补充说明一种理由，因此，for引导的从句几乎可以放在括号里。For
14、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“是否”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 dont know whether (if) he likes that film.在下列情况下，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
15、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 havent made up my mind whether to go there or not.（4）sothat, such.that1) sothat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：Im so tired that I cant walk any farther.It was such a warm day that he went swim
16、ming.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）eitheror, neithernor, not onlybut 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 no
17、r his children like fish. Not only the teacher but also the students want to buy the book.（6）although, but这两个连词不能用在同一个句子中。例如：我们不能说“Although he is over sixty, but he works as hard as others.”这个句子应改为：Although he is over sixty, he works as hard as others.或He is over sixty, but he works as hard as other
18、s.（7）because, so这两个连词同样不能用在同一个句子中。例如：我们不能说“Because John was ill, so I took him to the doctor.” 这个句子应改为Because John was ill, I took him to the doctor.或John was ill, so I took him to the doctor.【演练】 1.

The flower isnt beautiful. 2. 陈述句否定式的构成(1) 如果肯定陈述句的谓语部分含有助动词、情态动词或连系动词be，则只需在这些动词后加not即可构成否定式。 He is play
27、ing the guitar.（肯定）He is not playing the guitar.（否定） We can get there before dark.（肯定） We cant get thee before dark.（否定）(2) 如果陈述句的谓语动词是实义动词，而其中又没有情态动词或助动词时，则需根据人称和时态在该实义动词前加dont, doesnt或didnt。同时把该实义动词变为原形。 He plays the violin well.（肯定） He doesnt play the violin well.（否定） She won the game.（肯定） She di
28、dnt win the game.（否定）(3) 如果句子是there be结构或谓语动词是have（有），除了be和have之后加not之外，句中如果有some要变为any。例如：There is some water in the cup. There is not any water in the cup.He has some books. He has not any books.(4) 除not以外，否定词no, never, nothing, nobody, few等也可构成否定句。例如：There is something wrong with his bike. There
29、is nothing wrong with his bike.I have seen the film. I have never seen the film.二. 祈使句的构成形式及基本用法 祈使句是用来表示命令、请求、建议、号召等的句子，谓语动词用原形，句末用感叹号“！”或句号“.”。朗读时一般用降调。1. 肯定的祈使句：（1）祈使句主语是you时，you常省略，但如果要特别强调对方或表达某种强烈的情绪时可以有主语或称呼语。 Be quiet. You be quiet!（2）“Do+祈使句”表示一种强烈的感情或请求，do起强调作用。 Do come back at once! Do be
30、 careful.（3）please用在祈使句中可以表示一种客气的语气，但please用在句末时，必须用逗号与其余部分分开。 Open the window, please.（4）Let引导祈使句时，后面需跟上人称代词或称呼语，人称代词一般只用第一、第三人称。 Let Jack wait a minute. Lets go to school.（5）在祈使句中，Lets和 Let us是有区别的。Lets包括说话者，而Let us不包括听话者在内。这点从反意疑问句时可明显看出。 Lets go skating, shall we?（表示内部的建议） Let us try again, will you?（表示向别人发出请求） 2. 否定祈使句通常以Dont或Never开头。其结构通常是：“Dont(Never)+动词原形+其他成分” 例如： Dont do that again! Never leave todays work for tomorrow! Dont be late next time!三. 一般疑问句、特殊疑问句、选择疑问句、反意疑问句的构成形式及基本用法1. 一般疑问句： （1）一般疑问句
