考点16状语从句考点总结考点01状语从句在句中作状语，用来修饰主句中的形容词,副词或动词。状语从句分为:时间状语从句、地点状语从句、原因状语从句、结果状语从句、条件状语从句、让步状语从句、比较状语从句、方式状语从句和目的状语从句。考点02 在时间状语从句和条件状语从句中用一般现在时代替一般将来时；用一般过去时代替过去将来时。I will help you if you are in trouble.如果你有麻烦我将帮助你。When it rains I will take out my raincoat.当下雨时，我将拿出雨衣。考点03 引导时间状语从句的连词有: while , when, as soon as, since, ever since, once, until, till, before, after 等。注意：when 引导从句可表示正在那时那刻。All the students are laughing when the teacher comes in.所有的学生都在笑，正在这时老师进来了。When I miss you , I will visit you.我想念你时，我会去看你。考点04 when,while和as的区别：when,while,as三个词译成中文都是“当……时候”。when既可以指“点时间”也可指“段时间”；while只能指“段时间”，因此while后面只接延续性动词；as意为：“一边……一边……”，强调从句的动作和主句的动作同时发生。While I am watching TV, my aunt visits my house.当我看电视时，我阿姨来了我家。She reads the letter as she walks along the river.她一边沿着河走，一边读这封信。考点05 till和until的区别：till,和until 都表示 “直到……”，until多用于句首。在肯定句中, 两个词都表示“直到……为止”，主句应用延续性动词；在否定句中，两个词都表示“直到……才”，主句应用终止性动词。I didn’t get up until the doorbell rang.直到电话响起我才起床。They sit there until the class is over.他们坐在那里直到下课。考点06 引导地点状语从句的连词有:where等。Where there is a will,there is a way.有志者，事竟成。考点07引导原因状语从句的连词有:because,as,since,now that (既然),seeing that (鉴于)。考点08 because,as,since和for的区别：because表示直接原因，回答why的提问；since表示显而易见或已知原因，语气较轻；as 表示已知原因；for表示推测原因,或附加、补充说明,不能用在句首。---Why are you late?---Because I miss the bus.－你为什么迟到了？－因为我没赶上公交车。Since you are tired, you’d better have a rest.既然你累了，最好休息一会儿。It must have rained last night for the ground is wet.昨晚肯定下雨了，因为地面湿了。真题演练 一．选择题（共10小题）1．（2021•济南）My hometown has changed a lot in the past few years.You           the changes if you come.（　　）A．see B．saw C．will see D．have seen2．（2021•东营模拟）﹣How long have you been studying at this school？﹣I have been studying here______ .（　　）A．since I was thirteen years old B．when I was thirteen C．at the age of thirteen D．after I was thirteen3．（2020•延庆区一模）He'll send us a message as soon as he ________ in Sichuan．（　　）A．is arriving B．will arrive C．arrived D．arrives4．（2021•中山市模拟）﹣Do you know if she ____ to visit us？﹣I think she will come if she ____ free tomorrow．（　　）A．comes，is B．will come，is C．comes，will be D．will come，will be5．（2021•临沂模拟）Though the car was so expensive，________ he still decided to buy it．（　　）A．so B．or C．but D．/6．（2021•北京）I will send you an e﹣mail as soon as I            in  Canada．（　　）A．arrive B．arrived C．am arriving D．will arrive7．（2021•汕头）﹣If our government _____attention to controlling food safety now，our health _____in danger．（　　）A．won't pay，is B．doesn't pay，is C．won't pay，will be D．doesn't pay，will be8．（2021•阜新）If it ______ sunny tomorrow， we will have a picnic near the river．（　　）A．will be B．be C．is D．was9．（2021•历城区一模）﹣Look， what have you done？﹣﹣Sorry， if I _____ another chance， I'll do it better．（　　）A．will have B．have had C．had D．have10．（2021•咸宁）﹣Let's go to the community if it           tomorrow．﹣But nobody knows if it           tomorrow．（　　）A．won't rain； rains B．doesn't rain； rains C．doesn't rain； will rain D．won't rain； will rain
