  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 fly, he gave a loud cry.   She looked behind from time to time as she went   5) 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,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 wasn’t ready, we left without him.   Since I have no money, I can’t 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, whether   if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 don’t 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 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...that   1) 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 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 others.   (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.   【实例解析】   1.(2004年北京市中考试题)   ---When will Mr Black come to Beijing?   ---___________ September 5.
