高考英语语法复习---状语从句一、状语从句的分类及常用连接词Eg: When I was a child, I liked reading.I found the book where I left it.Please do as I tell you.He was so excited that he forgot to say bye.Though he was tired, he went on working.As long as you like, I will agree with you.Eg:When he will come is still unknown.I don’t know the place where he was born.在时间,条件和让步状语从句中,注意时态和省略二、相似连词的用法区别1. while, as, when三者都可以引导时间状语从句,表示主句动作发生的背景。
例如:When/ As/ While we were still laughing, the teacher came in.区别:1) when 既可以引导一持续性动作,又可引导一短暂性动作;它可以表示主句的动作和从句的动作同时发生,或从句的动作发生在主句的动作之前。
例如:When I was a boy, I used to go to the seashore on Sundays. (同时)When you have finished your work, you may have a rest. (从句动作发生在主句动作之前)2) as引导一持续性动作,侧重于表示主句和从句的动同时发生,但持续时间一般较短。
例如:John sang as he worked.从句表示“随时间推移”,也只能用as。
例如:As the day went on, the weather got worse.日子一天天过去,天气越变越坏。
专题八 状语从句、定语从句状语从句一、时间状语从句1.before 引导的从句中不用否定式谓语。
常用如下句型: It is long before...(过了好久才……) It is not long before...(过了不久就……)2.since 后面所用动词不同,该动词所表示动作持续时间的计算方法也不同。
⎩⎪⎨⎪⎧since +瞬间动词过去式从该动作发生时算起since +持续性动词过去式从动作结束时算起It is two years since he joined the army. It is two years since he smoked. 二、地点状语从句多由where 和wherever 引导。
Where there is a will ,there is a way. 二、原因状语从句在表示原因时,because 语气最重,其次是as ,since ,now that ,故在回答why 问句或者在强调句对原因进行强调时,只能用because 。
for 是并列连词,表示推测的理由或者进一步说明,不能放在句首,for 前要用逗号。
—Why were you absent? —Because I was ill. 三、目的状语从句1.so that/in order that 引导的目的状语从句中的谓语动词多用can/could/may/might/will/would +动词。
Please turn off the light so that I can go to sleep. 2.for fear that ,in case ,lest 表示“以防,免得”。
He is working hard for fear that he should fail. 四、条件状语从句1.providing/provided (that)假如,假若Providing (that) no one has further questions ,the meeting will be over. 2.on the understanding that =on condition that 在……条件下I give you money on the understanding that you finish your homework.五、结果状语从句注意such 引导的结果状语从句与定语从句的区别。
