分词前也可加一个连词(最新整理)

1、在英语中当我们用分词或分词短语作状语，表示时间，地点，条件，让步时， 我们还可以用连词加分词或分词短语这一结构。这种结构在句中相当于状语从句。例如：1、表示时间：常由 while, when, whenever, once, until 引起。例如：1）when crossing the street , look out for the cars coming and going.(=whenyou cross the street, look out for the cars coming and going.)过马路时，要当心来往车辆。2） when seen from space, t

2、he earth looks blue,(=when the earth is seen from space, it looks blue.)从太空看地球时，地球呈蔚蓝色。3） once seen, it can never be forgotten,(=once it is seen, it can never be forgotten.)过目不忘。4） he did not take part in the evening party until invited. (=he did not take part in the evening until he was invited.)有人

3、邀请他以后他才参加了那些晚会。5）while staying in the countryside, he learned a lot from the peasants.（=while he stayed in the countryside, he learned a lot from the peasants.）他住在农村时，从农民那儿学到许多东西。6）well go there whenever needed.(=well go to the place whenever we are needed.)什么时候需要我们去那儿，我们就什么时候去那儿。2、表示地点，常用 where, wh

4、erever 引起。例如：1) we should go where needed.(we should go where we are needed.)什么地方需要我们，我们就去什么地方？2） we must be strict with ourselves wherever being.(=we must be strict with ourselves wherever we are.)我们在任何地主都应从严要求自己。3） the difficult points should be crossed out where met with . ( = the difficult point

5、s should crossed out where they are met with . 一碰到难点，就要把它们标出来。3、表示让步，常由 though，although，even though，even if 引起。例 如 ：1）though being a student，be never does hs homework . ( = though he isstudent，he never does his homework .)尽管他是一个学生，但他从来都不做作业。2）though forbidden to smoke in class，he still smokes in cla

6、ss sometimes.（=though he is forbidden to smoke in class，he still smokes in class sometimes .） 虽然不允许他上课的时候抽烟，但他有时上课时还是抽烟。4、表示条件，常用 if，unless 引起。例如：1） if heated，water changes into vapor. （= if water is heated，it changes vapor.）如果水被加热，就会变成水蒸汽。2） unless criticized，he would made the same mistake again.（=

7、 unless he was criticized，he would make the same mistake again .）如果不批评他，他还会犯同样的错误。注意：after 既可作连词也可作介词，所以，当 after 作连词时，后面跟时间状语从句，作介词时后面只能跟动名词，不能跟过去分词。例如：福尔摩斯把房子仔细察看后，又把房子锁了起来。错误：after examined carefully by mr. holmes，the room was locked again.正确：after being examined carefully by mr. holmes，the room w

8、as locked again.正 确 ：after the room was examined carefully by mr. holmes, it was locked again. 和状从句相似，分词前也可加一个连词，来使分词所表示 的时间、条件或让步关系更清楚：while listening（=while she was listening） to the radio， she fell in a swoonbefore speaking（before you speak）， you must think over what you are to say when going to
