2、o,等。,第3页,隶属连词,隶属连词用来引导从句。常见隶属连词有:,(1)引导时间状语从句,after,before,when,while,as,until,till,since,as soon as,等。,(2)引导条件状语从句,if,unless,等。,(3)引导原因状语从句,because,as,since,等。,(4)引导目标状语从句,so that,in order that,等。,(5)引导让步状语从句,though,although,even if,等。,(6)引导结果状语从句,so that,sothat,suchthat等。,(7)引导比较状语从句,than,asas,等。,
3、8)引导宾语从句,that,if,whether,等。,第4页,惯用连词使用方法辨析,(1)while,when,as,这三个连词都可引导时间状语从句,但使用方法有所不一样。,1)当某事正在进行时候,又发生了另一件事。While,when,as 都可用来引导表示“背景”时间状语从句。比如:,As/When/While I was walking down the street I noticed a police car.,2)当两个长动作同时进行时候,最惯用是while。比如:,While mother was cooking lunch,I was doing my homework,.
4、3)当两个动作都表示发展改变情况时,最惯用是as。比如:,As children get older,they become more and more interested in things around them.,第5页,4)当两个短动作同时发生时,或表示“一边一边”时,最惯用as。比如:,Just as he caught the fly,he gave a loud cry.,She looked behind from time to time as she went,5)当从句动作先于主句动作时,通惯用when。比如:,When he finished his work,he
5、 took a short rest.,6)当从句是瞬间动作,主句是延续性动作时,通惯用when。比如:,When John arrived I was cooking lunch.,第6页,(2)as,because,since,for,这四个词都可表原因,但使用方法有区分。,1)假如原因组成句子最主要部分,普通用because。所以,because引导从句往往放在句末。比如:,I stayed at home because it rained.,-Why arent you going?,-Because I dont want to.,.,第7页,2)假如原因已被人们所知,或不如句子其
6、它部分主要,就用as或since。Since比as稍微正式一点。As和since 引导从句普通放在句子开头。比如:,As he wasnt ready,we left without him.,Since I have no money,I cant buy any food.,3)for用来补充说明一个理由,所以,for引导从句几乎能够放在括号里。For引导句子不放在句子开头。比如:,I decided to stop and have lunch-for I was feeling quite hungry.,第8页,(3)if,whether,if和whether都可作“是否”讲,在引导
7、宾与从句一时般可交换。比如:,I wonder,whether(if),you still study in that school.,I dont know,whether(if),he likes that film.,在以下情况下,只能用whether,不能用if:,1)引导主语从句时。比如:,Whether,he will come to the party is unknown.,2)引导表语从句时。比如:,The question is,whether,I can pass the exam.,3)在不定式前。比如:,I havent made up my mind,whether
8、to go there,or not,.,第9页,(4)sothat,such.that,1)sothat中so是个副词,其后只能跟形容词或副词,而such.that中such是个形容词,后接名词或名词短语。比如:,Im,so,tired,that,I cant walk any farther.,It was,such,a,warm,day,that,he went swimming.,2)假如在名词之前有,many,much,little,few,时,用,so,不用such。比如:,He has,so,little,education,that,he is unable to get a
9、 job.,I have had,so,many,falls,that,I am black and blue all over.,第10页,(,5)eitheror,neithernor,not onlybut also,这三个连词词组都可连接两个并列成份。当它们连接两个并列主语时,,谓语动词要随相邻主语改变,。(,就近标准,)比如:,Either you or,he,is,wrong.,Neither he nor,his children,like,fish.,Not only the teacher but also the,students,want,to buy the book.
10、第11页,(6)although,but,这两个连词不能用在同一个句子中。比如: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 others.,第12页,(7)because,so,这两个连词一样不能用在同一个句子中。比如:我们不能说“,Because,John was ill,so,I took hi
11、m 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.,第13页,【实例解析】,3.(年吉林省中考试题),-I like riding fast.Its very exciting.,-Oh!You mustnt do it like that,_ it may have an accident.,A.and B.or C.so D.but,答案:,B,。该题考查是并列连词使用方法。答语意思是“你不要那样做,不然会发生事
12、故。”在这四个并列连词中,只有or含有这么意思,所以应选B。,第14页,4.(年天津市中考试题),John fell asleep _ he was listening to the music.,A.after B.before C.while D.as soon as,答案:,C,。,该题考查是引导时间状语从句惯用隶属连词使用方法。本句含义是“约翰在听音乐时候睡着了。”表示在干某事时发生了某个事情”通惯用while。所以应选C。,第15页,【中考演练】,1.-Will the foreigners have any problems talking with Chinese in?,-I
