大哥,你这问的也太含糊了。好歹也说下你的教材是什么出版社的,这样别人也好给答案。
不过,我个人认为你在网络上问这种总结语法的问题还不如自己买本高一的英语辅导书,那个才比较能帮助你

一. 直接引语和间接引语 (一)直接引述别人的原话,叫做直接引语;用自己话转述别人的话,叫做间接引语。间接引语一般构成宾语从句。直接引语必须放在引号内,间接引语则不用引号。直接引语改为间接引语时,除将引语部分变成宾语从句外,还必须对直接引语中的人称、时态、指示代词、时间状语、地点状语等进行改变。 1. 时态的变化:直接引语变为间接引语时,通常受转述动词said, asked等的影响而使用过去化的时态,即把原来的时态向过去推,也就是一般现在时变为一般过去时,现在进行时变为过去进行时,等等。例如: Tom said to me,“My brother is doing his homework.” →Tom said to me that his brother was doing his homework. 2. 人称代词、指示代词、时间状语、地点状语等等的变化: 根据意义进行相应的变化,例如: She asked Jack,“Where have you been?” →She asked Jack where he had been. He said,“These books are mine.” →He said that those books were his. (二)直接引语改为间接引语时,都使用陈述语序,但是因为原句的句式不同,所以变成间接引语时所用的连词会有所不同。直接引语如果是一般疑问句,用连接词whether或if;如果是特殊疑问句,则用疑问词引导间接引语。转述的动词一般用asked,可以在其后加上一个间接宾语me, him, her, us等。如: She said,“Is your father at home?” →She asked me if/whether my father was at home. “What do you do every Sunday?”My friend asked me. →My friend asked me what I did every Sunday. 直接引语如果是祈使句,改为间接引语时,要将祈使句的动词原形变为带to的不定式,并在不定式的前面根据原句的语气(即请求或命令)加上ask, tell, order等动词,如果祈使句为否定式,则在不定式前加not。其句型为:ask / tell / order someone (not) to do something. 例如: She said to us,“Please sit down.” →She asked us to sit down. He said to him,“Go away!” →He ordered him to go away. He said, “Don’t make so much noise, boys.” →He told the boys not to make so much noise. 二. 各种时态的被动语态 被动语态概述 被动语态的概念:它是动词的一种形式,表示主语与谓语之间的执行或被执行关系。主动语态表示主语是谓语动作的执行者,例如:They saw the little boy crying by the river. 被动语态表示主语是谓语动作的承受者,例如:The little boy was seen crying by the river. 被动语态的构成 被动语态的形式是由“助动词be+动词的过去分词”构成。助动词be随着主语的人称、数、时态等的不同而变化。几种常见时态的被动语态形式如下: 1. 一般现在时 am/is/are + 过去分词 例如:Rice is planted in the south of China. 2. 一般过去时 was/were + 过去分词 例如:These trees were planted the year before last. 3. 一般将来时 will/shall + be + 过去分词 例如:A sports meeting will be held next week in our school. 4. 现在进行时 am/is/are + being + 过去分词 例如:Your radio is being repaired now. 5. 过去进行时 was/were + being + 过去分词 When he got there, the problem was being discussed. 6. 现在完成时 have/has + been + 过去分词 His work has been finished. Has his work been finished? Yes, it has. / No, it hasn’t. 7. 过去完成时 had + been + 过去分词 注意: 1.除了be之外的其它系动词如get, stay等也可以和过去分词构成被动语态。例如:Their questions haven’t got answered. 2. 含有情态动词的谓语变成被动语态使用“情态动词+ be + 过去分词”结构。例如: More attention should be paid to the old in this country. This work can’t be done until Mr. Black comes. 3. 含有“be going to”, “be to”等结构的谓语,其被动语态分别用“be going to + be + 过去分词”和“be to + be + 过去分词”。例如: The problem is going to be discussed at the next meeting. All these books are to be taken to the library. 4. 被动语态与系表结构的区别:“连系动词+用作表语的过去分词”构成的系表结构,与被动语态的形式完全一样,所以应注意它们的区别。被动语态中的过去分词是动词,多强调动作;系表结构中的过去分词相当于形容词,多强调状态。前者通常可用by 引出动作的执行者,而后者则不可以。例如: The map was changed by someone.(被动结构) That custom remained unchanged for many centuries.(系表结构) 系表结构中的过去分词通常可被very修饰,被动语态中的过去分词往往要用much修饰。 例如: He was very excited.(系表结构) He was much excited by her words.(被动结构) 5. 主动形式表被动意义。有些动词的主动形式有被动意味,如 open, read, sell, shut, wash, wear, write等。此时句子的主语一般是物。例如: These books sell well. 这些书很畅销。 The door won’t shut. 这门关不上。 The clothes wash well. 这些衣服很好洗。

7. 高一英语知识点及语法
(一)直接引述别人的原话,叫做直接引语;用自己话转述别人的话,叫做间接引语。间接引语一般构成宾语从句。直接引语必须放在引号内,间接引语则不用引号。直接引语改为间接引语时,除将引语部分变成宾语从句外,还必须对直接引语中的人称、时态、指示代词、时间状语、地点状语等进行改变。
1. 时态的变化:直接引语变为间接引语时,通常受转述动词said, asked等的影响而使用过去化的时态,即把原来的时态向过去推,也就是一般现在时变为一般过去时,现在进行时变为过去进行时,等等。例如:
Tom said to me,“My brother is doing his homework.”
→Tom said to me that his brother was doing his homework.
2. 人称代词、指示代词、时间状语、地点状语等等的变化: 根据意义进行相应的变化,例如:
She asked Jack,“Where have you been?”
→She asked Jack where he had been.
He said,“These books are mine.”
→He said that those books were his.
(二)直接引语改为间接引语时,都使用陈述语序,但是因为原句的句式不同,所以变成间接引语时所用的连词会有所不同。直接引语如果是一般疑问句,用连接词whether或if;如果是特殊疑问句,则用疑问词引导间接引语。转述的动词一般用asked,可以在其后加上一个间接宾语me, him, her, us等。如:
She said,“Is your father at home?”
→She asked me if/whether my father was at home.
“What do you do every Sunday?”My friend asked me.
→My friend asked me what I did every Sunday.
直接引语如果是祈使句,改为间接引语时,要将祈使句的动词原形变为带to的不定式,并在不定式的前面根据原句的语气(即请求或命令)加上ask, tell, order等动词,如果祈使句为否定式,则在不定式前加not。其句型为:ask / tell / order someone (not) to do something. 例如:
She said to us,“Please sit down.”
→She asked us to sit down.
He said to him,“Go away!”
→He ordered him to go away.
He said, “Don’t make so much noise, boys.”
→He told the boys not to make so much noise.
二. 各种时态的被动语态
被动语态概述
被动语态的概念:它是动词的一种形式,表示主语与谓语之间的执行或被执行关系。主动语态表示主语是谓语动作的执行者,例如:They saw the little boy crying by the river. 被动语态表示主语是谓语动作的承受者,例如:The little boy was seen crying by the river.
被动语态的构成
被动语态的形式是由“助动词be+动词的过去分词”构成。助动词be随着主语的人称、数、时态等的不同而变化。几种常见时态的被动语态形式如下:
1. 一般现在时 am/is/are + 过去分词
例如:Rice is planted in the south of China.
2. 一般过去时 was/were + 过去分词
例如:These trees were planted the year before last.
3. 一般将来时 will/shall + be + 过去分词
例如:A sports meeting will be held next week in our school.
4. 现在进行时 am/is/are + being + 过去分词
例如:Your radio is being repaired now.
5. 过去进行时 was/were + being + 过去分词
When he got there, the problem was being discussed.
6. 现在完成时 have/has + been + 过去分词
His work has been finished.
Has his work been finished? Yes, it has. / No, it hasn’t.
7. 过去完成时 had + been + 过去分词
注意:
1.除了be之外的其它系动词如get, stay等也可以和过去分词构成被动语态。例如:Their questions haven’t got answered.
2. 含有情态动词的谓语变成被动语态使用“情态动词+ be + 过去分词”结构。例如:
More attention should be paid to the old in this country.
This work can’t be done until Mr. Black comes.
3. 含有“be going to”, “be to”等结构的谓语,其被动语态分别用“be going to + be + 过去分词”和“be to + be + 过去分词”。例如:
The problem is going to be discussed at the next meeting.
All these books are to be taken to the library.
4. 被动语态与系表结构的区别:“连系动词+用作表语的过去分词”构成的系表结构,与被动语态的形式完全一样,所以应注意它们的区别。被动语态中的过去分词是动词,多强调动作;系表结构中的过去分词相当于形容词,多强调状态。前者通常可用by 引出动作的执行者,而后者则不可以。例如:
The map was changed by someone.(被动结构)
That custom remained unchanged for many centuries.(系表结构)
系表结构中的过去分词通常可被very修饰,被动语态中的过去分词往往要用much修饰。
例如:
He was very excited.(系表结构)
He was much excited by her words.(被动结构)
5. 主动形式表被动意义。有些动词的主动形式有被动意味,如 open, read, sell, shut, wash, wear, write等。此时句子的主语一般是物。例如:
These books sell well. 这些书很畅销。
The door won’t shut. 这门关不上。
The clothes wash well. 这些衣服很好洗。

动词的语气——虚拟语气(The Subjunctive Mood)
一、语气的定义和种类
l、语气:语气是动词的一种形式,它表示说话人对某一行为或事情的看法和态度。
2、语气的种类:
(1)陈述语气: 表示动作或状态是现实的、确定的或符合事实的,用于陈述句、疑问句和某些感叹句。如:We are not ready. 我们没准备好。What a fine day it is!多好的天气啊!
(2)祈使语气: 表示说话人的建议、请求、邀请、命令等。如: Open the door, please。请打开门。
(3)虚拟语气: 表示动作或状态不是客观存在的事实,而是说话人的主观愿望、假设或推测等。如: If I were you, I should study English. 如果我是你,我就学英语了。May you succeed! 祝您成功!
二、虚拟语气在条件从句中的用法
条件句有两类,一类是真实条件句,一类是虚拟条件句。如果假设的情况是有可能发生的,就是真实条件句。在这种真实条件句中的谓语用陈述语气。如: If it doesn’t rain tomorrow, we will go to the park. 如果明天不下雨,我们就去公园。
如果假设的情况是过去或现在都不存在的,或将来不大可能发生的,则是虚拟条件句。如:
If he had seen you yesterday, he would have asked you about it. 如果他昨天见到你,他会问你这件事的。(事实上他昨天没见到你,因此也未能问你这件事。)
在含有虚拟条件句的复合句中,主句和从句的谓语都要用虚拟语气。现将虚拟条件从句和主句的动词形式列表如下:
与现在事实相反: 从句: 动词的过去式(be的过去式一般用were)
主句:would/ should/ could/ might + 动词原形
与过去事实相反 : 从句 :had + 过去分词
主句 :would/ should/ could/ might + have + 过去分词
与将来事实相反 : 从句:动词过去式,should + 动词原形,
主句 :were to + 动词原形 would/ should/ could/ might + 动词原形
注: 主句中的should只用于I、we,但在美国英语中,should常被would代替;从句中的should可用于各种人称。
l、表示与现在事实相反的假设和结果。如: If my brother were here, everything would be all right. 要是我哥哥在这儿 ,一切都没问题了。
2、表示与过去事实相反的假设和结果。如: If you had taken my advice,you wouldn't
(couldn’t) have failed in the exam. 如果你按照我的建议去做,你一定不会(不可能)考试不及格。
3、表示与将来事实可能相反的假设和结果。如: If it were Sunday tomorrow, I should
(would,could,might) go to see my grandmother. 如果明天是星期天,我就 (可能)去看望我奶
奶。If it were to snow this evening, they would not go out. 如果今晚下雪,他们将不出去了。
4、有时条件从句中的动作和主句中的动作发生的时间不一致(表示错综时间的虚拟语气),这时动词的形式要根据它所表示的时间加以调整。例如: If you had listened to the doctor, you would be all right now. 如果你当初听了医生的话,身体现在就好了。(从句动作指过去,主句动作指现在)
5、虚拟条件句可以转换成下列形式:
(l)省略连词if。在书面语中,如果虚拟条件从句中有were,had 或 should,可以把if省略,把这几个词放到主语之前,构成主谓倒装。例如: Should he come (If he should come), tell him to ring me up. 他要是来了,让他给我打个电话。Were I you (If I were you), I would not do it. 我要是你,就不做这事。
(2)用介词短语代替条件状语从句。有时假设的情况并不用条件从句表示出来,而是通过介词短语来表示。如: Without air (If there were not air), there would be no living things. 如果没有空气的话,就不会有生物了。But for your help (If it hadn’t been for your help) I couldn’t have done it. 要是没有你的帮助,我就不可能完成这件事。
假设的情况有时可以通过上下文或其他方式表现出来。如: I was busy that day. Otherwise I would have gone there with them. (If I hadn’t been busy that day, I would have gone there with them.) 我那天很忙,否则,我就和他们一起去那儿了。(如果我那天不忙的话,我就……);I would have finished the work, but I have been ill. (If I hadn’t been ill, I would have finished the work.) 我本来该完成这项工作的,但我生病了。(如果我没生病的话,我就会完成……)
6、省去条件从句或主句:表示虚拟语气的主句或从句有时可以省略,但其含义仍可以推知。
(1)省去条件从句。如: You could have washed your clothes yourself. 你本可以自已洗衣服的。省去了"If you had wanted to")(事实是:你自己没洗衣服,因为你不想洗。)
(2)省去主句(常用以表示愿望)。如: If my grandmother were with me! 如果我的祖母与我在一起多好啊!(事实是:祖母已不在世。);If only she had not left! 如果她没走就好了!(事实是:她已经走了。)
三、虚拟语气的其他用法
l、虚拟语气在主语从句中的用法:在"It is important (strange,natural,necessary)that…"这类句型里,that所引导的主语从句中的谓语动词常用 “should+动词原形”结构,表示某事是"重要"、"奇怪"、"自然"、"必要"等意义。如: It is important that every member (should) inform himself of these rules. 重要的是每个成员知道这些规则。
2、虚拟语气在宾语从句中用法:
(1)在动词wish后的宾语从句中,表示与现在或过去的事实相反,或对将来的主观愿望,从句通常省略连词that。1)表示对现在情况的虚拟:从句动词用过去式或过去进行式(be动词一般用were)。如: I wish I knew the answer to the question. 我希望知道这个问题的答案。(可惜不知道);2)表示对过去情况的虚拟:从句动词常用"had+过去分词"。如: I wish (wished) I hadn’t spent so much money. 我后悔不该花那么多钱。(实际上已经花掉);3)表示对将来的主观愿望:谓语动词形式为"would+动词原形"。此时要注意,主句的主语与从句的主语不能相同,因为主句的主语所期望的从句动作能否实现,取决于从句主语的态度或意愿(非动物名词除外)。如: I wish it would stop raining. 但愿雨能停止;I wish you would come soon. 但愿你立刻来。
(2)在suggest,demand,order,propose,insis

主句 :were to + 动词原形 would/ should/ could/ might + 动词原形
注: 主句中的should只用于I、we,但在美国英语中,should常被would代替;从句中的should可用于各种人称。

4、有时条件从句中的动作和主句中的动作发生的时间不一致(表示错综时间的虚拟语气),这时动词的形式要根据它所表示的时间加以调整。例如: If you had listened to the doctor, you would be all right now. 如果你当初听了医生的话,身体现在就好了。(从句动作指过去,主句动作指现在)

(If I hadn’t been ill, I would have finished the work.) 我本来该完成这项工作的,但我生病了。(如果我没生病的话,我就会完成……)
6、省去条件从句或主句:表示虚拟语气的主句或从句有时可以省略,但其含义仍可以推知。
(1)省去条件从句。如: You could have washed your clothes yourself. 你本可以自已洗衣服的。省去了"If you had wanted to")(事实是:你自己没洗衣服,因为你不想洗。)
(2)省去主句(常用以表示愿望)。如: If my grandmother were with me! 如果我的祖母与我在一起多好啊!(事实是:祖母已不在世。);If only she had not left! 如果她没走就好了!(事实是:她已经走了。)
三、虚拟语气的其他用法
l、虚拟语气在主语从句中的用法:在"It is important (strange,natural,necessary)that…"这类句型里,that所引导的主语从句中的谓语动词常用 “should+动词原形”结构,表示某事是"重要"、"奇怪"、"自然"、"必要"等意义。如: It is important that every member (should) inform himself of these rules. 重要的是每个成员知道这些规则。
2、虚拟语气在宾语从句中用法:
(1)在动词wish后的宾语从句中,表示与现在或过去的事实相反,或对将来的主观愿望,从句通常省略连词that。1)表示对现在情况的虚拟:从句动词用过去式或过去进行式(be动词一般用were)。如: I wish I knew the answer to the question. 我希望知道这个问题的答案。(可惜不知道);2)表示对过去情况的虚拟:从句动词常用"had+过去分词"。如: I wish (wished) I hadn’t spent so much money. 我后悔不该花那么多钱。(实际上已经花掉);3)表示对将来的主观愿望:谓语动词形式为"would+动词原形"。此时要注意,主句的主语与从句的主语不能相同,因为主句的主语所期望的从句动作能否实现,取决于从句主语的态度或意愿(非动物名词除外)。如: I wish it would stop raining. 但愿雨能停止;I wish you would come soon. 但愿你立刻来。
(2)在suggest,demand,order,propose,insist,command,request,desire等动词后的宾语从句中,谓语动词用“should + 动词原形”,表示建议、要求、命令等。如: I demand that he (should) answer me immediately. 我要求他立刻答复我。
3、虚拟语气在状语从句中的用法
(1)在带有even if/ even though引导的让步状语从句的主从复合句中,主句和从句都用虚拟语气,动词形式与含有非真实条件句的虚拟语气相同。如: Even if he had been ill, he would have gone to his office. 即使生了病,他都去办公室。
(2)由as if或as though引导的状语从句表示比较或方式时。从句谓语形式为动词的过去式(be用were)或 “had+过去分词”。如: He treated me as if I were a stranger. 他那样对待我,好像我是陌
生人似的。She talked about the film as if she had really seen it. 她谈论那部影片,就好像她确实看过一样。
注:如果表示的事情可能会发生,那么方式状语从句中的谓语动词可用陈述语气。
(3)在in order that或so that引导的目的状语从句中,谓语动词多用 “could或might(有时也用should)+ 动词原形”。如: Mr green spoke slowly so that his students could (might) hear clearly. 格林先生说得很慢,好让学生听清楚。
4、虚拟语气在定语从句中的用法:在"It is time (that) …"句型中,定语从句的谓语动词常用虚拟语气表示将来,动词形式一般用过去式,意思是"该干某事的时候了"。如: It’s (high) time we did our homework. 我们该做作业了。
5、虚拟语气在简单句中的用法
(1)情态动词的过去式用于现在时态时,表示说话人的谦虚、客气、有礼貌,或委婉的语气,常见于日常会话中。如: It would be better for you not to stay up too late. 你最好别太晚睡觉。
(2)在一些习惯表达中。如: I would rather not tell you. 我宁愿不告诉你。
(3)用“may + 动词原形”表示"祝愿"、"但愿”,此时may须置于句首(多用于正式文体中)。如:May you be happy!祝你快乐!May good luck be yours.祝你顺利。
