watch TV _I am having breakfast,When的用法,并列连词when常用与以下句型中：was/were doingwhen（正在做突然）was/were about to dowhen（刚要做突然）was/were on the point of doingwhen(刚要做突然)had just donewhen.(刚一就)Hardly/Scarcely haddonewhen(刚一就),I was about to go out _ the telephone rang.A.whenB.suddenly C.as soon as D.directlyWe were swimming in the lake _ the storm started.A.whenB.suddenly C.untilD.before,They kept trying _

to do as I did.4.As she was late for class,she had to say sorry.,before引导的时间状语从句,before引导从句时,词义非常灵活，注意下列句子中的before的词义：1.Before I could get in a word,the tailor had measured me.(还没来得及就)2.We hadnt run a mile before he felt tired.(还没就)3.We had sailed 4 days before we saw land.(才)4.Please write it down before you forget it.(趁还没),He made a mistake,but then he corrected the situation _ it got

some time _ she is completely well.A.thatB.since C.whenD.beforeThey sat down opposite each other,but it was some moments _ they spoke.A.afterB.before C.sinceD.when,几个极易混淆的时间状语从句：,1）It was+时间点+when（当的时候时间是）It was 5 am when we arrived at the village.2）It was/will be+时间段+before(没过就过了才)It was/will be two weeks before we met/meet again.3）It is/has been+时间段+since（自从以来有）It is/has been 3 years since we last met.突破点：一看be动词的时态，二看时间段还是时间点。注意：在“It is/has been+时间段+since”句型中，从句的动词必须是短暂性的，如果是延续性的动词，时间要从从句的动作结束时算起。如：It is 3 years since I smoked.(我戒烟有三年了),it is+时间+since before when thatIt is five years _he finished his research.It was five years _he finished his research.It was five years later _he finished his research.It was 5 oclock _ he got home.It was at 5 oclock _ he got home.,when,that,since,before,that,till(until)和nottill(until),1）till(until):主句谓语动词必须是持续性的，意思是“到为止“如：He remained there till/until she arrived.2）nottill(until):主句谓语动词必须是短暂性的，意思是“直到才”如：She wont go to bed till/until he returns home.3）notuntil还有强调式和倒装式：强调句：It is not until he returns home that she will go to bed.倒装句：Not until he returns home will she go to bed.,条件状语从句,常见的从属连词有：if,unless,as/so long as,as/so far as,on condition that,in case(万一),the more,the more等。如：,Mother asked me to take more money _ something unexpected should happen.A.in case B.so that C.in order thatD.when,in case 起连词作用，用以引导状语从句，主要有两种意思：一是表示条件，意为“如果”、“万一”；二是表示目的，意为“以防”、“免得”。,(1)_ I forget,please remind me about it.A.In caseB.So that C.In order that D.When(2)Take your umbrella just _ it rains.A.in caseB.so that C.in order that D.when,“Shall Mary come and play computer games?”“No,_ she has finished her homework.”A.whenB.since C.unlessD.as soon as,此句为省略句，答句句首的 No 表明其后省略的是一个否定句，全句补充完整为：She cant play computer games unless she has finished her homework.,(1)“Would you mind my sitting here with you?”“No,_ you arent too noisy.”A.whenB.if C.unlessD.as soon as(2)“Will he agree to come to join us in the work?”“No,_ we promise him more money.”A.whenB.unless C.untilD.as soon as,原因状语从句,常见的从属连词有：because,since,now that,as等。,注意because,since,as和for的区别：,）because的语气最强，它引导的从句比主句更重要，从句的位置可前可后；例外回答why的问句必须使用because。如：-Why were you absent from the meeting yesterday?-Because I was ill.2)since和now that意思是“既然”，语气仅次于because,从句的位置一般在前。如：Since everybody is here,lets begin our meeting3)as的语气比since更弱，意思是“由于”，从句的位置可前可后。如：As you didnt turn up at yesterdays get-together,we missed you very much）*for也有“因为”之意，但for是并列连词常用来来补充说明原因或用来表示推断的依据，前面常带逗号。如：It must have rained last night,for the ground is wet,1.Because he was ill,he didnt go to school.2._ you do not understand,I will explain again.3.As she was late for class,she had to say sorry.4._class is over,lets go to play football.5.He must be ill,_he is absent today.,Since,Now that,for,1.“May I go and play with Dick this afternoon,Mum?”“No,you cant go out _ your work is being done.”A.before B.until C.asD.the moment,让步状语从句,常见的从属连词有：though,although,as,even if/though,no matter wh-，wh-ever,whetheror等。如：However late/No matter how late he is,his family will wait for him to have dinner together.Child as he is,he knows a lot.(as引导的让步状语从句必须倒装)Whether it is fine or not,I will go boating,_he is old,he works hard._you say
