高一英语知识点：直接引语和间接引语
eg: “I broke your CD player.” (一般过去时改成过去完成时)
He told me he had broken my CD player.
Jenny said, “I have lost a book.”
(现在完成时改成过去完成时)
Jenny said she had lost a book.
Mum said, “I’ll go to see a friend.”
(一般将来时改成过去将来时)
Mum said she would go to see a friend.
过去完成时保留原有的时态
He said, “We hadn’t finished our homework.”
He said they hadn’t finished their homework.
注意 直接引语是客观真理，过去进行时，时态不变。
2. 在直接引语变间接引语时，如果从句中的主语时第一人称或被第一人称所修饰，从句中的人称要按照主句中主语的人称变化。如：
Mary said, “My brother is an engineer.”
Mary said her brother was and engineer.
3. 直接引语如果是反意疑问句，选择疑问句或一般疑问句，间接引语应改为由whether或if引导的宾语从句。如：
He said, “Can you run, Mike?”
He asked Mike whether/if he could run.
4. 直接引语如果是祈使句，间接引语应改为“tell(ask, order, beg等) * (not) to do sth.”句型。如：
“Pass me the water, please.”said he.
He asked him to pass her the water.
5. 直接引语如果是以“Let’s”开头的祈使句，变为间接引语时，通常用“suggest+动名词或从句”的结构。如：
She said, “Let’s go to the cinema.”
She suggested going to the cinema.
或She suggested that they should go to the cinema.
现在进行时表将来的动作
现在进行时表将来的动作，谓语通常为瞬间动词。如：come, go, arrive, leave, start, return, stay, meet, get等。这些动词的进行时后不能再接具体的时间。
(1)用现在进行时表示将来，指的是近期的，按计划或安排要发生的动作。
(2)现在进行时表示将来与表示正在进行的动作的区别在于：前者通常用瞬间动词(有时一些常用动词也可以这样用如：do)如：go, come, start, return, get, arrive等。而后者通常是持续性动词。
He is reading a novel.
他在看小说。
The train is arriving soon.
火车就要进站了。
(3)用现在进行时表示将来的时间，在句中或上下文中通常有表示将来时间的状语。
(4)现在进行时与一般现在时表示将来动作的区别在于：前者表示的将来的动作往往是可以改变的，而后者则是根据规定或时间表预计要发生的动作或事情，因此往往是不可改变或不可随便改变的。
What are you doing next Friday?
下星期五你们打算干什么?
The plane takes off at 7：30 tonight.
飞机今晚七点半起飞。
高一英语知识点：助动词
一.概念:
助动词是帮助主要动词构成各种时态,语态,语气以及否定或疑问结构的动词.助动词分为时态助动词和结构助动词两种.
二.相关知识点精讲:
1. 助动词be的用法
1) be +现在分词，构成进行时态。例如：
They are having a meeting. 他们正在开会。
English is becoming more and more important. 英语现在越来越重要。
2) be + 过去分词，构成被动语态。例如：
The window was broken by Tom.. 窗户是汤姆打碎的。
English is taught throughout the world. 世界各地都教英语。
3) be + 动词不定式，可表示下列内容：
a. 表示最近、未来的计划或安排。例如：
He is to go to New York next week.. 他下周要去纽约。
We are to teach the freshmen. 我们要教新生。
说明： 这种用法也可以说成是一种将来时态表达法。
b. 表示命令。例如：
You are to explain this. 对此你要做出解释。
He is to come to the office this afternoon. 要他今天下午来办公室。
c. 征求意见。例如：
How am I to answer him? 我该怎样答复他?
Who is to go there? 谁该去那儿呢?
d. 表示相约、商定。例如：
We are to meet at the school gate at seven tomorrow morning. 我们明天早晨7点在校门口集合。
2. 助动词have的用法
1)have +过去分词，构成完成时态。例如：
He has left for London. 他已去了伦敦。
By the end of last month, they had finished half of their work. 上月未为止，他们已经完成工作的一半。
2)have + been +现在分词，构成完成进行时。例如：
I have been studying English for ten years. 我一直在学英语，已达十年之久。
3)have +been +过去分词，构成完成式被动语态。例如：
English has been taught in China for many years. 中国教英语已经多年。
3.助动词do 的用法
1)构成一般疑问句。例如：
Do you want to pass the CET? 你想通过大学英语测试吗?
Did you study German? 你们学过德语吗?
2)do + not 构成否定句。例如：
I do not want to be criticized. 我不想挨批评。
He doesn't like to study. 他不想学习。
In the past, many students did not know the importance of English.
过去，好多学生不知道英语的重要性。
3) 构成否定祈使句。例如：
Don't go there. 不要去那里。
Don't be so absent-minded. 不要这么心不在焉。
说明： 构成否定祈使句只用do，不用did和does。
4)放在动词原形前，加强该动词的语气。例如：
Do come to my birthday party. 一定来参加我的生日宴会。
I did go there. 我确实去那儿了。
I do miss you. 我确实想你。
5)用于倒装句。例如：
Never did I hear of such a thing. 我从未听说过这样的事情。
Only when we begin our college life do we realize the importance of English. 进了大学以后，我们才认识到英语的重要性。
说明： 引导此类倒装句的副词有never, seldom, rarely, little, only, so, well等。
6)用作代动词。例如：
---- Do you like Beijing? --你喜欢北京吗?
---- Yes, I do. --是的，喜欢。(do用作代动词，代替like Beijing.)
He knows how to drive a car, doesn't he? 他知道如何开车，对吧?
4. 助动词shall和will的用法
shall和will作为助动词可以与动词原形一起构成一般将来时。例如：
I shall study harder at English. 我将更加努力地学习英语。
He will go to Shanghai. 他要去上海。
说明：在过去的语法中，语法学家说shall用于第一人称，will 只用于第二、第三人称。现在，尤其是在口语中，will常用于第一人称，但shall只用于第一人称，如用于第二、第三人称，就失去助动词的意义，已变为情态动词，试比较:
He shall come. 他必须来。(shall有命令的意味。)
He will come. 他要来。(will只与动词原形构成一般将来时。)
5.助动词should, would的用法
1)should无词义，只是shall的过去形式，与动词原形构成过去将来时，只用于第一人称。例如：
I telephoned him yesterday to ask what I should do next week. 我昨天给他打电话，问他我下周干什么。
比较："What shall I do next week?" I asked. "我下周干什么?"我问道。
可以说，shall变成间接引语时，变成了should。
2) would也无词义，是will的过去形式，与动词原形构成过去将来时，用于第二、第三人称。例如：
He said he would come. 他说他要来。
比较："I will go," he said. 他说："我要去那儿。"变成间接引语，就成了He said he would come。原来的will变成would，go变成了come.。
6. 短语动词
动词加小品构成的起动词作用的短语叫短语动词。例如：
Turn off the radio. 把收音机关上。(turn off是短语动词)
短语动词的构成基本有下列几种：
1)动词+副词，如：black out;
2)动词+介词，如：look into;
3)动词+副词+介词，如：look forward to。构成短语动词的副词和介词都统称为小品词
高一英语知识点：动词的语气
一.概念
语气有三种:陈述语气,祈使语气和虚拟语气.语气表示说话人对劝词所示示的动作或所处的状态持有的态度或看法.
二.相关知识点精讲
1.辨别if 引导真实条件句和if引导的虚拟条件句的区别
If he has time, he will go with us.= Probably he has time and will go with us.
If he had time, he would go with us.=But in fact he has no time.
2.虚拟条件句中主句和从句的谓与动词构成形式如下表
3.混合时间的虚拟语气
如果条件句中的动作和主句的动作不是同时发生，主句和从句的谓语动词的形式应分别根据各自所表示的时间加以调整。
1)0If I had received the passport yesterday, I would start today.
2)If he had telephoned me last night, I would see him now.
3)If he had followed the doctor’s advice, he would be all right now.
4)If China had not been liberated, the working people would still be leading a miserable life.
4.should/ could / might/ ought to + have done 表示“过去本应该/可以做而实际上却没做”
needn’t have done 表示“过去没必要作而实际上做了”
5.虚拟语气中的倒装句
如果虚拟语气的条件从句谓语动词中含有were, had, could, should，有时可将if省去，而将条件从句的主语置于were, had, should, could 之后。
Had you invited us, we would have come to your party.
Were I you, I would do more practice after class.
Could she lend us a helping hand, she would do so.
6.wish 后面的宾语从句的谓语动词应使用虚拟语气， 表示“可惜…;….就好了; 悔不该…; 但愿…。”
1)I wish I knew the key to the answer.
2)I wish I were ten years younger.
3)I wish that I had gone to the football match last week.
4)I wish that you had been here yesterday.
5)He wishes that we would visit the old school.
7.表示命令或建议动词suggest, insist, propose, desire, demand, request, order, command 后的宾语从句中应使用虚拟 should +动词原形; should 不可用would 来替代; 主句所使用的动词时态不限。
8.suggest 为“建议去做…; 命令…”从句用should + do
为“ 说明; 暗示”, 从句用过去时或过去完成时。
1) The doctor suggested that I should take the medicine three times a day.
2) The doctor suggested that my grandmother had caught a bad cold.
9.insist “坚持要去做…，坚持应该去做”，从句用should + do为“坚持表明，坚持说/解释”， 从句用过去时或过去完成时。
10.虚拟语气也用于表语从句和主语从句中，表示间接的命令、要求、请求、建议、决定等，主句的主语通常是suggestion, proposal, request, order, idea 等。表语从句中的谓语动词是should +动词原型，should 可以省略。
11.在主语从句中，当从句用来表示惊奇、不相信、惋惜等，从句的谓语动词用需拟语气形式。其谓语动词时should + 动词原型， 或should 省略。
高一英语知识点：动词的语态
一.概念:
动词的语态是动词的一种形式,表示主语和谓语之间语法或语义的关系.英语的语态有两种:主动语态和被动语态.主动语态用于主动句,表示主语是动作的执行者.被动语态用于被动句,表示主语是动作的承受者.主动语态的构成方式与动词时态相同,而被动语态由 助动词be+过去分词 构成,有人称,数,时态的变化.
相关知识点精讲
1. let 的用法
1)当let后只有一个单音节动词，变被动语态时，可用不带to 的不定式。例如：
They let the strange go.他们放陌生人走了。
---> The strange was let go.
2)当let 后宾补较长时，let 通常不用被动语态，而用allow或permit 代替。例如：
The nurse let me go to see my classmate in the hospital. 那护士让我去探望住院的同学。
----> I was allowed / permitted to see my classmate in the hospital.
2.短语动词的被动语态
短语动词是一个整体，不可丢掉后面的介词或副词。例如：
My sister will be taken care of by Grandma. 我妹妹由奶奶照顾。
Such a thing has never been heard of before. 这样的事闻所未闻。
3. 表示"据说"或"相信" 的词组，基本上由believe, consider, declare, expect, feel , report, say, see, suppose, think, understand等组成。例如：
It is said that… 据说
It is reported that… 据报道
It is believed that… 大家相信
It is hoped that… 大家希望
It is well known that… 众所周知
It is thought that… 大家认为
It is suggested that… 据建议
It is taken granted that… 被视为当然
It has been decided that… 大家决定
It must be remember that… 务必记住的是
4. 不用被动语态的情况
1) 不及物动词或不及物动词短语，如appear, die disappear, end(vi. 结束), fail, happen, last, lie, remain, sit, spread, stand, break out, come true, fall asleep, keep silence, lose heart, take place等没有无被动语态。例如：
After the fire, very little remained of my house. 大火过后，我家烧得所剩无几。
比较：rise, fall, happen是不及物动词;raise, seat是及物动词。
要想正确地使用被动语态，就须注意哪些动词是及物的，哪些是不及物的。特别是一词多义的动词往往有两种用法。解决这一问题唯有在学习过程中多留意积累。
2) 不能用于被动语态的及物动词或动词短语，如fit, have, hold, marry, own, wish, cost, notice, watch agree with, arrive at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong to等。例如：
This key just fits the lock. 这把钥匙只配这把锁。
Your story agrees with what had already been heard. 你说的与我们听说的一致。
3) 系动词无被动语态，如appear, be become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn等。例如：It sounds good. 听上去不错。
4) 带同源宾语的及物动词如die/death, dream/dream， live/life等，以及反身代词，相互代词，不能用于被动语态。例如：
She dreamed a bad dream last night. 她昨晚做了个恶梦。
5) 当宾语是不定式时，很少用于被动语态。例如：
(对) She likes to swim.
(错) To swim is liked by her.
5. 主动形式表示被动意义
1)wash, clean, cook, iron, look, cut, sell, read, wear, feel, draw, write, sell等。例如：
The book sells well. 这本书销路好。
This knife cuts easily. 这刀子很好用。
2)blame, let(出租), remain, keep, rent, build等。例如：
I was to blame for the accident. 事故发生了，我该受指责。
Much work remains. 还有许多活要干。
3) 在need, require, want, worth (形容词), deserve后的动名词必须用主动形式。例如：
The door needs repairing.= The door needs to be repaired. 门该修了。
This book is worth reading. 这本书值得一读。
4)特殊结构：make sb. heard / understood (使别人能听见/理解自己)等。例如：
Explain it clearly and make yourself understood. 解释清楚些，让别人理解你的话。
6. 被动形式表示主动意义，如 be determined, be pleased, be graduated (from), be prepared (for), be occupied (in), get married等。例如：
He is graduated from a famous university. 他毕业于一所有名的大学。
注意：表示同某人结婚，用marry sb. 或get married to sb.均可。例如：
He married a rich girl. 他与一个富妞结婚了。
He got married to a rich girl.
7.need/want/require/worth
当 need, want, require, be worth后面接doing时，表示的是被动意义。例如：
