初三英语中考语法考点重难点详解(七)状语从句的时态知识点整理总结(含主将从现)
初三英语中考语法考点重难点详解（七）状语从句的时态知识点整理总结（含主将从现）中考英语对状语从句的考查，主要集中在时间状语从句和条件状语从句，首先要知道状语从句的作用，描述主句动词发生的“样子”：发生的时间、地点、条件、原因等等。
1、主句是祈使句或者含有情态动词的现在式，这个时候，从句多用一般现在时，例如：He can pass the exam if he studis hard.Tell me if he comes.2、主句用过去进行时，从句用一般过去时，例如：Mom was cooking when I got home.She was praticing the piano when I called.这种情况本质就是过去进行时的功能：表达过去某个时间点正在发生的动作，而从句中的动词往往是个瞬间动词，这个动作的发生（如got home，called）刚好对应着过去的一个“时间点”。
3、主句从句都用过去进行时，这个时候连词用while，例如：While I was doing my homework, mom was cooking in the kitchen.I was sitting in the sun while wy wife was working in the garden.这种情况其实是考试连词while的含义：在……的过程中，这样从句的动词就需要一个“延续性”动词，才能和while 配合完美。
4、关于条件句的用法，是出题人最喜欢采用的If he comes, give him the picture.（主句是祈使句，天剑局是一般现在时）If we try our best, we'll get good grades.主将从现是一般原则，但是要注意也有很多不是主将从现的主从句配合。
补充知识点：“主将从现”首先我们知道一个句子的成分包含，“主谓宾定状补”，那么在句中作状语的从句称为状语从句。

人教版英语九年级全册Unit7(语法透视)：含情态动词的被动语态
【语法透视】：含情态动词的被动语态1.含情态动词的被动语态的根本构造为“情态动词+be+及物动词的过去分词〞。
Many trees should be planted on the mountains. 应该在山上植许多树。
Students should be allowed to go to school by bike.应该允许学生们骑自行车上学。
2.把含情态动词的主动句变成被动句，即把“情态动词+动词原形〞改为“情态动词+be+过去分词〞，此时，作主语的要用动词承受者。
We should clean the classroom every day.→The classroom should be cleaned every day.(1)否认句：在情态动词后加not就行。
These books can’t be read for children. 这些书孩子们不能读。
(2)一般疑问句：直接将被动语态的陈述句的情态动词提到的句首。
Should Ann be allowed to choose her own clothes? 应该允许安选择自己的衣服吗？(3)特殊疑问句：由疑问词加上含有情态动词的被动语态的一般疑问句构成。
When must my homework be handed in? 我的作业必须何时交？4.对含有情态动词的被动语态的一般疑问句的答复，一般应保存原句中的情态动词，但must表示“必须〞时，其否认答复用needn’t。
—Should my homework be finished today? 我的作业应在今天完成吗？—Yes, it should./No, it shouldn’t. 是的，应在今天完成。
/不，不应在今天完成。
—Must the room be cleaned right now? 房间必须马上清扫吗？—Yes, it must./No, it needn’t. 是的，必须立即清扫。

连词的用法（下）二、常用从属连词的用法1．从属连词that 的用法：（1）引导宾语从句，在口语中，that可以省略。
如：I think (that) he is very tired. 我想他很累了。
（2）如果主句谓语动词是think, believe, guess时，如果主句的主语是第一人称，变为否定句时，要否定主语，但在翻译成汉语后，则要否定从句。
如：I don’t believe you will leave here.我相信你不会离开这里的。
（3）引导定语从句，在句中可以作主语和宾语，这时它既可以指人，又可以指物。
如：The cakes that my mother makes are delicious. 我妈妈做的蛋糕很好吃。
Do you know the girl that is standing by the lake? 你认识那个站在湖边的女孩吗？2．连词when, while, till, until, after, before, as soon as的用法：这些连词都可以连接时间状语从句，此时必须注意：while所引导的从句的谓语动词只能是延续性的。
并且在这些词语引导的时间状语从句中，如果主句的谓语动词是一般将来时，从句的位于动词要用一般现在时。
如：When I went there, it was snowing. 当我到那儿时，天正在下雪。
I entered the room while Li Ping was talking with Zhang Hong. 当我走进房间时，李萍正在和张红谈话。
Please don’t get off the bus until it stops.知道车停下来再下车。
He had learned some Chinese before he came to China. 他在来中国之前就学过一些汉语。
As soon as I get enough money, I’ll buy a computer.我一得到足够的钱，就买一台计算机。

中考英语语法专题详解七专题七情态动词、系动词在英语中，表示主语动作或状态的词就叫做动词。
根据动词的意义及在句子中的作用，可将动词分为实义动词(v)、系动词(link-v)、情态动词(modal verb)和助动词(v. aux)四种类型。
下面我们就来看看情态动词和系动词的具体用法。
一、情态动词情态动词本身有一定的意义，但不能独立作谓语，要和动词原形一起构成谓语，表说话人的语气和态度。
它没有人称和数的变化。
常见的情态动词有：1. can表示能力，有“能”“会”的意思;表示可能性，多用在否定或疑问句中;表示请求和许可。
如：The parrot can speak three languages. 这只鹦鹉能讲三种语言。
Can I borrow the book from the library?我可以从图书棺借这本书吗?Shanghai can be very cold in March. 上海三月份可能会很冷。
拓展延伸can还有过去式could 可表“能，会”，又可以和be able to替换，而be able to有更多时态。
如：He could swim when he was four. =He was able to swim when he was four. 他四岁时就会游泳。
在一般疑问句中，can/could 常用来表示请求或征求对方意见，用could 比用can语气更加委婉和客气。
类似用法的还有Will /Would you (please)…等句型。
如：Could you tell me how I can get to the post office? 你能告诉我怎样到邮局吗? Would you please turn up the radio?请你把收音机开大点，好吗?2.may表示“许可”时，相当于can，其否定回答用can’t/mustn’t;表推测时，常用在肯定句中，表“可能”。
如：-May I borrow your ruler?我可以借用您的直尺吗?-No, you can't /mustn't. 不行。
She may be a teacher. 她可能是一名教师。
拓展延伸may可表示祝愿。
如：May you succeed! 祝你成功!3.must表示“必须;必要”，以“must”开头的一般疑问句其肯定回答用“must”，否定回答用“needn't”或“don't have to”。
must表推测时，常用在肯定句中，是“一定”的意思，其否定形式mustn ' t表“禁止”的意思。
如：-Must I leave now?现在我必须离开吗?-No，you needn't /you don't have to. 没有必要。
This book must be Lucy's . Look! Her name is on the book cover. 这本书是露西的。
看!封面上还有她的名字。
You mustn't draw on the wall. 你不准在墙上画画。
拓展延伸must表示说话人的主观看法，只有一般现在时;have to强调客观要求，有时态、人称和数的变化。
如：My mother is ill. I have to look after her now. 妈妈病了，我得去照看她。
4.need作情态动词时，常用在否定和疑问句中，表示“需要;要”的意思。
如：Need we finish the work now?现在我们需要完成这项工作吗?They needn ' t look after him. 他们不需要照顾他了。
拓展延伸need还可以用作行为动词，可以用于各种句型。
如：Does he need any help? 他需要帮助吗?The desk needs repairing. 这张桌子需要修理。
5.shall 用于第一人称，表示说话人征求对方意见，过去式为should;will 用手第二人称的疑问句中，表示说话人向对方提出请求和建议，过去式为would。
如：Shall I go shopping with you?'我可以同你去购物吗?I don't know what I should do next. 我不知道下一步该干什么。
Would you please come a little earlier?请你来早一点好吗?6.情态动词had better的用法(1)had better 后接动词原形，表劝告、建议，意为“最好”。
“You'd better…”含有强制命令的语气，对长辈不宜使用。
如：You'd better ask that policeman over there. 你最好问一下那边的那个警察。
(2)慎用had better! 注意以下四条：①had better表达的是说话者强硬性的建议，告诫别人(包括自己)如何做。
如：Granny, the hospital is not very near. We'd better catch a bus. 奶奶，医院不是很近。
我们最好坐公共汽车。
②had better不用于礼貌的请求或征询，它隐含一种警告或威胁。
如：You ' d better finish the work today and bring it tomorrow. 你最好今天就把作业完成，明天带来。
③had better意思接近should，但它除了表示语气强硬以外，还表示马上要去做的事情，比should更紧迫。
如：You’d better see a doctor at once. 你最好马上去看医生。
④had better不含比较的意思，该结构表示“It would be good to…”，而不是“It would be better to…”。
二、系动词系动词有实际意义，但不能单独做谓语，必须与表语一起构成句子的谓语，说明主语的性质、状态或身份等。
它分为完全系动词和不完全系动词。
1.完全系动词(be)可接名词、代词、形容词、副词、介词短语、非谓语动词短语、句子做表语。
如：I'm a student. 我是个学生。
(名词) He is fine. 他很好。
(形容词) It is me. 是我。
(代词) Are you there?你在那儿吗?(副词) She is at school. 她在学校读书。
(介词短语) He is to come soon. 他过会儿该来了。
(不定式) My job is teaching English. 我的工作是教英语。
(动词的ing形式) My idea is that we will start now. 我的想法是我们现在就开始。
(句子)2.不完全系动词(get，turn，feel，smell，look，sound，taste)一般只接形容词做表语。
如：When spring comes, it gets warmer and warmer.春天来了，天气变得越来越暖和了。
Food may go bad soon if it is not put into a fridge.食物如果不放进冰箱里就会很快变坏。
My brother became / turned a teacher after his graduation.我哥哥毕业后就当上了老师。
