小升初语法第15讲：连词（二）知识点讲解与考题精练（有答案）连词（Conjunction）是用来连接词与词、词组与词组或句子与句子，表示某种逻辑关系的虚词。连词表示并列、转折、选择、因果等关系。如：“Youandme.你和我。”“和”就是连词，表示并列。“Youorme.你或者我。”“或者”也是连词，表示选择。连词是一种虚词，不能独立担任句子成分，起前后连接作用，类似桥梁。连词主要分为并列连词和从属连词。【知识点】从属连词从属连词是用来连接从句和主句的连词。从属连词后面连接的句子是从句，另一个句子是主句。常用的从属连词有when,before,after,assoonas,because,if,though,although等。按从属连词引导的从句将其分为以下四类。引导时间状语从句的从属连词when“当.....时”Iwasasleepwhenyousentmethemessage.你给我发消息时，我睡着了。as“正当.....时”AsIgotintotheclassroom,theteacherleft.我进教室时，老师离开了。while“在.....同时”Lisacalledwhilehermomwascooking.丽萨打电话时她妈妈正在做饭。before“在.....之前”Heknockedthedoorbeforehecamein.他进来之前敲了门。after“在.....之后”Aftershearrivedhome,itbegantorain.她到家之后开始下雨了。引导原因状语从句的从属连词because“因为”Ididn’tfinishmyhomeworklastnightbecauseIwasillthen.我昨晚没完成作业是因我生病了。since“因为，既然”Sinceyouarebusy,I’lldothecookingtoday.既然你忙，今天我来做饭吧。as“因为，由于”Asitisraininghard,we’dbetterstayinside.由于下大雨，我们最好待在室内。引导条件状语从句的从属连词if“如果”IfIamateacher,Iwillmakefriendswithmystudents.如果我是一个老师，我会跟我的学生交朋友。unless“除非”Iwon’tgotothepartyunlessyougowithme.我不会参加那个聚会，除非你陪我去。引导让步状语从句的从属连词although/though“虽然，尽管”Although/Thoughitwasrainingheavily,hestillarrivedontime.虽然天下大雨，他还是准时到达。★though（虽然）与but（但是）不能连用Thoughhewastired，hestillworkedhard.
