初升高英语衔接课件：第8讲 并列句和状语从句
课堂是教育教学是主阵地。高三年级教学时间紧，教学任务重，更要切实发挥 课堂40分钟的作用。一是上好微专题课。春节前后，一轮复习进入后期，学生 不会的知识点逐步浮出水面。这些薄弱知识点如果解决不好，将直接影响到二 轮复习的效果。高三年级要围绕浮现出来的问题，上好微专题或微微专题课， 针对某一个点或几个点精讲、讲透，触类旁通。微专题课怎么上？可以针对学 生不会的问题，每节课重点解决1-2个知识点，专题强调，专点训练，不贪多， 顺一个点“追祖宗八代”，剖析透!微微专题，则更精、更准、更小、更有效，可 以一节课只讲一道题，但是要把这一道题挖深、挖透，讲透一个会一类，做会 一题能举一反三。

◆regular exercise is very important, it’s never a good idea to exercise too close to bedtime.2．even if 和even though的意思为“即使，纵使”，有退一步设想的意味，多用于书面语中。
◆I am very busy, I will give you a hand when you are in trouble.3．as引导的让步状语从句多用于书面语，从句常放在句首，语序部分倒装。
被倒装的部分可以是表语、状语或动词原形。
若表语是单数可数名词，则该名词提前时，省去其前的冠词。
◆Hot the night air was, we slept deeply because we were so tired after the long journey.4．no matter(who, what, when, where, which, how…)：n o matter…与wh－ever引导的让步状语从句意义基本一样，no matter…引导的从句可位于主句前或主句后。
◆busy you are, you should set aside half an hour to take exercise.5．wh－ever(whatever/whoever/whenever/wherever/whichever); however。
(1)wh－ever从句中的动词有时可以和may连用；(2)wh－ever可引导让步状语从句，也可引导名词性从句；no matter…只能引导让步状语从句。
◆you like, I ‘ll buy it for you.I ‘ll buy you like.6．whether…or…引导的让步状语从句，意为“不论……还是……”，提供两种对比情况。
◆We’ll go on with the work, we can find the necessary tools we cannot.不管我们能否找到所需的工具，我们都要把这件工作做下去。
7．while也可以引导让步状语从句，意为“尽管”，一般放在句首。
◆my mother loves me very much, she is very strict with me.(2015·浙江高考短文改错)If I was only a child when I studied in that classroom, I will never forget it.考点二、时间状语从句1．when, while和as的用法连词含义及用法例句when “当……时候”，可与延续性动词或短暂性动词连用；从句动作可以发生在主句动作之前、之后或与主句动作同时发生. you apply for a job, you mustpresent your credentials.while “当……时候”，一般与延续性动词连用，从句动作与主句动作同时发生Please don’t talk so loud othersare working.as “一边……一边……”，“随着……”，从句动作与主句动作同时或交替发生. he grew older, he became lessactive.He looked behind he went.如果主句表示的是短暂性动作，而从句用延续性动词的进行时表示在一段时间内正在进行的动作时，when, while与as可互换使用。
◆When/While/As I was walking down the street, I came across an old friend of mine.我正沿着大街走时，碰巧遇到了我的一个老朋友。
2．before与since的用法(1)before表示“在……之前；还未……就……；还没来得及……就……”。
常用于句型“It will be/was＋时间段＋before从句”(在……之前还要多久，过了多久才……)。
◆John thinks it won’t be long he is ready for his new job.(2)since表示“自从……以来”，常用于“It is/has been＋时间段＋since从句”结构。
该句型表示“自从开始(不做)……已经多长时间了”，一般从句的时态用一般过去时，主句中的时态用现在完成时。
◆As is reported, it is over 100 years Tsinghua University was founded.3．not…until…表示“直到……才”◆As far as I know, his mother (go) to bed he returns home every evening.4as soon as/hardly…when/no sooner…than/the momen t/the instant/the second/immediately/directly/instantly hardly…when和no sooner…than的意义相当于as soon as，但只表示过去发生的事情，主句为过去完成时，从句为过去时，hardly或no sooner位于句首时语气强，而且主句的谓语要用部分倒装。
◆Just use this room for the time being, and we’ll offer you a larger one it becomes available.I had hardly got home when it began to rain.--We had no sooner arrived at the station than the train left.--5．every time/each time/last time/next time/by the time：在时间状语从句中，不能用一般将来时或过去将来时，而要用一般现在时或一般过去时代替将来时。
◆Next time he (come) here, I will tell him.(全国卷Ⅰ改错)He even scared my classmates away during they came over to play or do homework with me.考点三、地点状语从句和条件状语从句1．地点状语从句表示地点、方位，通常由where，wherever引导，可置于句首、句中或句尾。
地点状语从句在句首时常兼有抽象条件意味。
◆I cannot hear the professor clearly as there is too much noise I am sitting.◆there’s a will, there’s a way.(重庆高考单项填空)Half an hour later, Lucy still couldn’t get a taxi ____________ the bus h ad dropped her.where引导的状语从句和定语从句的区别where引导地点状语从句直接修饰主句的谓语动词，而在定语从句中where作为关系副词要跟在表示地点的先行词后面，即此时有明显的地点名词。
◆When solving the problem a second time, you’d better be more careful you made a mistake.＝When solving the problem a second time, you’d bett er be more careful in the place you made a mistake.2．条件状语从句常用引导词：if/unless/as long as/so long as/in case/so far as/as far as。
(1)unless从句的谓语只能用肯定式；unless和if…not同义，unless是书面语，if…not是口语，二者通常可以换用。
◆We will have a picnic in the park this Sunday it rains or it’s very cold.◆My parents don’t mind what job I do I am happy.(2)条件状语从句的时态在条件状语从句中，常用一般现在时表将来含义；现在完成时表即将完成之后的情况；一般过去时表过去将来的含义。
