1,psat simple ：一般过去时，表示过去完成的动作或过去的情境和习惯。 Eg: She climb the stairs and went to her room.
用一般过去时要在规则动词词尾加-ed，或用不规则动词的过去式，一般过去式的疑问句和否定句用did 和didn‘t 加动词原形。
2、past continuous过去进行时：过去某段时间正在进行的动作形成某些事件发生的情境动作。 Eg, It was raining during the whole match.
当过去进行时和一般过去时出现在同一个句子中时，过去进行时描述故事发生的背景，儿一般过去时则报道该事件。
Eg， We driving along a country lane when, suddenly a car drove past us. Form: 过去进行时的结构是：主语+was /were +动词-ing形式。 Eg， The driver was sitting behind the wheel.
四、present perfect and past simple。现在完成时和一般过去式，现在完成时表示发生在过去的事情对现在依然有明显的影响
发生在过去的动作但是不知道动作发生的时间或对动作发生的确切时间不感兴趣。 现在完成时经常和下列时间状语连用：

3、动作本身比动作执行者更重要或不想指出谁做的这件事。

If +past simple would /could /might +infinitive/without to 虚拟语气用法详解
英语中的语气分为陈述语气、祈使语气、虚拟语气三类。在表示虚假的、与事实相反的或难以实现的情况时用虚拟语气，表示主观愿望或某种强烈情感时，也用虚拟语气。即当一个人说话时欲强调其所说的话是基于自己的主观想法，愿望，假想，猜测，怀疑或建议，而不是根据客观实际，就用虚拟语气 一、 条件句中的虚拟语气 1. 条件句中虚拟语气的形式
从句中提出一种与客观现实不相符或根本不可能存在的条件，主句会产生的一种不可能获得的结果。条件句中的虚拟语气根据不同的时间有三种不同的形式。 时间 从句谓语形式 主句谓语形式 动词过去式(be用were) 将来 should + 动词原形 would / should / might / could + 动现在 过去 were to + 动词原形 动词过去式(be 用 were) had +动词过去分词 词原形 would / should / might / could + 动词原形 would / should / might / could have + 动词过去分词 2. 条件中的虚拟语气的举例 (1) 将来时的条件句中的虚拟语气。如：
If he should go to Qing Hua University, he would make full use of his time. 如果他要上清华大学的话，他就会充分利用他的时间了。
If he were to come here, he would tell us about it. 如果他要来的话，他会通知我们一声。 (2) 现在时的条件句中的虚拟语气。如：
If he were free, he would help us. 要是他有空的话，它会帮助我们的。
If he studied at this school, he would know you well. 如果他在这所学校学习的话，它会对你很熟悉。
(3) 过去时的条件句中的虚拟语气。如：
If I had seen the film, I would have told you about it. 我如果看过这场电影，我会把电影内容告诉你了。
If I had got there earlier, I would have met Mr. Li. 如果我早点到那儿，我就会会到了李先生。 3. 运用条件句中的虚拟语气时，须注意的几个问题
(1) 当从句的主语为第三人称单数时，谓语动词若是系动词be时，可用was代替were。但在倒装虚拟结构及if I were you, as it were中，只能用were。如：
Were I ten years younger, I would study abroad. 要是我还年轻十岁的话，我会去国外学习。 If I were you, I would try my best to grasp the chance. 要是我是你的话，我要尽力抓住这次机会。
(2) 有时，虚拟条件句中，主、从句的动作若不是同时发生时，须区别对待。 ①从句的动作与过去事实相反，而主句的动作与现在或现在正在发生的事实不符。如：
If I had worked hard at school, I would be an engineer, too. 如果我在学校学习刻苦的话，我现在也会使工程师了
If they had informed us, we would not come here now. 如果他们通知过我们的话，我们现在就不会来这里了。 ②从句的动作与现在事实相反，而主句的动作与过去事实不符。如：
If he were free today, we would have sent him to Beijing. 如果他今天有空的话，我们会已经派他去北京了。
If he knew her, he would have greeted her. 要是他认识她的话，他肯定会去问候她了。 ③从句的动作与过去发生的情况相反，而主句的动作与现在正在发生的情况相反。如：
If it had not been raining too much, the crops would be growing much better. 如果天不下太多的雨的话，庄家会长得更好。
If he had been working hard, he would be working in the office now. 要是他工作一直努力的话，他现在已进了办公室了。
(3) 当虚拟条件句的谓语动词含有were, should, had时，if可省略，而将were, should, had等词置于句首。如：
Should he agree to go there, we would send him there. 要是他答应去的话，我们就派他去。 Were she here, she would agree with us. 如果她在这儿的话，她会同意我们的。
Had he learnt about computers, we would have hired him to work here. 如果她懂一些电脑知识的话，我们会已经聘用他来这里工作了。
(4) 有时，句子没有直接给出假设情况的条件，而须通过上下文或其他方式来判断。如： I would have come to see you, but I was too busy. 我本该来看你了，然而我太忙了。 But for his help, we would be working now. 要不是他的帮助，我们还会在工作呢。
Without your instruction, I would not have made such great progress. 要是没有你的指导，我不会取得如此大的进步。
(5) 有时，虚拟条件句中，主、从句可以省略其中的一个，来表示说话人的一种强烈的感情。 ①省略从句
He would have finished it. 他本该完成了。
You could have passed this exam. 你应该会通过这次考试了。 ②省略主句

四、定语从句：defining and non-defining 限制性和非限制性定语从句 Ⅰ. 概念：
(1) 定语从句：在主从复合句中用作定语的从句叫定语从句。定语从句一般紧接在先行词(antecedent)后面。
(2) 先行词：被定语从句修饰的成份。先行词可以为一个词，短语，或整个主句。 (3) 引导定语从句的词叫关系词，分为关系代词和关系副词。 关系词的作用：
1) 引导定语从句，连接主句和从句，相当于一个连词；
2) 必在从句中作某个句子成份（可以做主语，宾语，表语，定语，状语）
常用的关系代词: that、 which、 who、whom、whose、as 、but (文语, 置于否定词之后=that/who…not…, \"没有……不……\在从句中作主语，宾语) 常用的关系副词（在从句中只作状语）: when、why、 where The student who answered the question was John. I know the reason why he was so angry.
The boy (whom) you are talking to is my brother. I'd like a room whose window looks out over the sea. 定语从句三步： 第一找出先行词；
第二看先行词在定语从句中的语法功能（做主语、宾语或状语）； 第三选择合适的关系词。 Ⅱ. 几个关系代词的基本用法：
●that: 可指人或物；在定语从句中作主语，宾语，表语。(指人时，相当于who或 whom；指物时，相当于which)(一般不用于非限制性定语从句; 不可置于介词后作宾语) 如： 1. A letter that/which is written in pencil is difficult to read. (主语) 2. Do you know the gentleman that/who spoke just now? 3. You can take anything ( that) you like. （宾语）
4. What is the question (that/which) they are talking about? 5. Here is the man ( who/whom/that ) you want to see.
6. She's no longer the girl ( that) she used to be before.（表语） 7. Our hometown is no longer the one (that) it used to be. = Our hometown is not the same as it used to be.

Beijing, which has been China's capital for more than 800 years , is rich in cultural and historic relics. 北京是中国八百年之久的古都，它有着丰富的文化和历史遗产。 4. 翻译时，限制性定语从句可译为一句（较短的一般译为\"的\"字结构）；而非限制性定语从句可译为两句。（见上句翻译）
比较: He has a sister, who is a musician. He has a sister who is a musician. 引导非限制性定语从句的关系代词，指人时用who, whom, whose , 指物时用which , whose; 关系副词when，where, why, etc.

1. He was late again, which made his teacher very angry.
2. Jack, as you know, is an honest man. 或Jack is an honest man , as you know. 或As you know, Jack is an honest man. ②先行词的不同：
as引导非限制性定语从句时，其先行词多为一个句子；

不定式的否定式是not to do. 五、 The passive 被动语态。
1，可用于不知道或不需要强调动作执行者时， The press conference will be held in the hotel lobby. 2, 动作的执行者很明确时。
3，要强调动作本身二不是强调谁做的这件事时。
4，有时，要强调的动作执行者时（人或物）通常在句末用by + 名词表示。
被动语态讲解
（一）、被动语态的构成形式 1. 被动语态的基本时态变化
被动语态通常为十种时态的被动形式, 被动语态由be＋过去分词构成，be随时态的变化而变化。以do为例，各种时态的被动语态形式为： 1) am/is/are +done (过去分词) 一般现在时
例Visitors are requested not to touch the exhibits. 2） has /have been done 现在完成时
例All the preparations for the task have been completed, and we're ready to start. 3） am/is /are being done 现在进行时 例A new cinema is being built here． 4） was/were done 一般过去时
例I was given ten minutes to decide whether I should reject the offer. 5） had been done 过去完成时
例 By the end of last year, another new gymnasium had been completed in Beijing. 6） was/were being done 过去进行时
例A meeting was being held when I was there. 7） shall/will be done 一般将来时
例Hundreds of jobs will be lost if the factory closes. 8） should/would be done 过去将来时
例The news would be sent to the soldier's mother as soon as it arrived. 9） shall/will have been done 将来完成时（少用） 例The project will have been completed before July. 2. 被动语态的特殊结构形式
1)带情态动词的被动结构。其形式为：情态动词＋be＋过去分词。 例The baby should be taken good care of by the baby-sitter.
2) 有些动词可以有两个宾语，在用于被动结构时，可以把主动结构中的一个宾语变为主
语，另一宾语仍然保留在谓语后面。通常变为主语的是间接宾语。
例His mother gave him a present for his birthday. 可改为 He was given a present by his
mother for his birthday.
3) 当―动词+宾语+宾语补足语‖结构变为被动语态时，将宾语变为被动结构中的主语，其余不动。
例Someone caught the boy smoking a cigarette. 可改为The boy was caught smoking a cigarette.
4）在使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后面不定式作宾语补语时，在主动结构中不定式to要省略，但变为被动结构时，要加to。 例Someone saw a stranger walk into the building. 可改为A stranger was seen to walk into the building.
5) 有些相当于及物动词的动词词组，如―动词＋介词‖，―动词＋副词‖等，也可以用于被动结构，但要把它们看作一个整体，不能分开。其中的介词或副词也不能省略。 例The meeting is to be put off till Friday. 3. 非谓语动词的被动语态
v.+ing 形式及不定式 to do 也有被动语态(一般时态和完成时态) 。
例I don't like being laughed at in the public.
（二）、 如何使用被动语态
学习被动语态时，不仅要知道被动语态的各种语法结构，还要知道在哪些情况中使用被动语态。
1. 讲话者不知道动作的执行者或不必说出动作的执行者 (这时可省 by 短语)。 例 My bike was stolen last night.
2. 借助被动的动作突出动作的执行者。
例 I was given ten minutes to decide whether I should accept the offer. 3. 为了更好地安排句子。
例The well-known person got on the bus and was immediately recognized by people. （一个主语就够了）
（三）、 It is said that+从句及其他类似句型
一些表示―据说‖或―相信‖的动词如believe, consider, expect, report, say, suppose, think等可以用于句型―It＋be＋过去分词＋that从句‖或―主语＋be＋过去分词＋to do sth.‖。有：
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。
例It is said that the boy has passed the national exam. （＝The boy is said to have passed the national exam. ）
（四）、谓语动词的主动形式表示被动意义
1.英语中有很多动词如 break，catch，clean，drive，lock，open，sell，read，write，wash等，当它们被用作不及物动词来描述主语特征时，常用其主动形式 表达被动意义,主语通常是物。
例 This kind of cloth washes well.
注意：主动语态表被动强调的是主语的特征，而被动语态则强调外界作用造成的影响。 试比较：The door won't lock． （指门本身有毛病）
The door won't be locked． （指不会有人来锁门, 指―门没有锁‖是人的原因） 2. 表示―发生、进行‖的不及物动词和短语，如：happen, last, take place, break out, come out, come about, come true, run out, give out, turn out等以主动形式表示被动意义。 例 How do the newspapers come out? 这些报纸是如何引出来的呢？
3. 系动词没有被动形式, 但有些表示感受、感官的连系动词feel, sound, taste, book, feel等在主系表结构中常以主动形式表示被动意义。 例Your reason sounds reasonable
（五）、非谓语动词的主动形式表被动意义
在某些句型中可用动名词和不定式的主动形式表被动意义 。
1． 在need，want，require, bear等词的后面，动名词用主动形式表示被动意义，其含义相当于动词不定式的被动形式。
例The house needs repairing（to be repaired）．这房子需要修理。 2． 形容词worth后面跟动名词的主动形式表示被动含义，但不能跟动词不定式；而worthy后面跟动词不定式的被动形式。
例The picture-book is well worth reading．（＝The picture-book is very worthy to be read．） 3. 动词不定式在名词后面作定语，不定式和名词之间有动宾关系时，又和句中另一名词或代词构成主谓关系, 不定式的主动形式表示被动含义。
例 I have a lot of things to do this afternoon． (to do与things是动宾关系，与I是主谓关系。)
试比较：I‘ll go to the post office. Do you have a letter to be posted? ( 此处用不定式的被动语态作定语表明you不是post动作的执行者。)
4. 在某些―形容词＋不定式‖做表语或宾语补足语的结构中，句子的主语或宾语又是动词不定式的逻辑宾语时，这时常用不定式的主动形式表达被动意义。这些形容词有nice，easy，fit，hard，difficult，important，impossible，pleasant，interesting等。
例This problem is difficult to work out .（可看作to work out省略了for me）.
5． 在too… to…结构中，不定式前面可加逻辑主语，所以应用主动形式表示被动意义。 例This book is too expensive (for me) to buy.
6. 在there be…句型中，当动词不定式修饰名词作定语时，不定式用主动式作定语，重点在人，用被动形式作定语，重点在物。
例There is no time to lose（to be lost）．（用 to lose可看成for us to lose；用to be lost，谁 lost time不明确。）
7. 在be to do结构中的一些不定式通常应用主动表主动, 被动表被动。然而,由于古英语的影响,下列动词rent,blame,let等仍用不定式的主动形式表示被动意义。 例 Who is to blame for starting the fire?
（六）、介词in, on, under等+名词构成介词短语表被动意义
表示方位的介词与含动作意义的名词合用，含被动之义，其意义相当于该名词相应动词的被动形式，名词前一般不用冠词。
1. ―under +名词‖结构，表示―某事在进行中‖。常见的有：under control（受控制）, under treatment（在治疗中）, under repair（在修理中）, under discussion（在讨论中）, under construction（在施工中）。
例The building is under construction( is being constructed).
2．―beyond+名词‖结构，―出乎……胜过……、范围、限度‖。常见的有：beyond belief (令人难以置信)， beyond one‘s reach（鞭长莫及），beyond one‘s control（无法控制），beyond our hope． 我们的成功始料不及。
例The rumour is beyond belief（=can‘t be believed）．
3.―above+名词‖结构, 表示―(品质、行为、能力等) 超过……、高于……‖。
例His honest character is above all praise．=His honest character cannot be praised enough．
4．―for+名词‖结构，表示 ―适于……、 为着……‖。如：for sale(出售), for rent（出租）等。 例That house is for sale. (= That house is to be sold). 5．―in+名词‖结构 ，表示―在……过程中或范围内‖常见的有：in print（在印刷中），in sight(在视野范围内)，等。
例The book is not yet in print．(=is not yet printed)
6．―on+名词‖结构, 表示―在从事…… 中‖。常见的有：on sale(出售)，on show（展出）, on trial（受审）。
例Today some treasures are on show in the museum (= are being showed).
7．―out of+名词‖结构 ； 表示 ―超出…… 之外―，常见的有：out of control (控制不了)，out of sight （超出视线之外），out of one‘s reach(够不着), out of fashion(不流行)等。 例 The plane was out of control (can‘t be controlled)． 。 8．―within+名词‖结构，―在……内、不超过……‖。
例He took two days off within the teacher's permission. 六、gerund 动名词
动名词（ing形式）在句中起名词的作用，可用作主语，表语，定语和宾语（用在动词或介词后）
Smoking is a terrible habit.(主语)
The advertising of products and services is big business.（主语） His hobby is colleting stamps.(表语) He doesn‘t like my singing.(宾语)
We are tired from working all day. (宾语) Where is the publishing house?(定语)
注意：不要混淆介词to 和不定式符号to (do) 动名词用于介词后。 I‘m looking forward to getting you early.
七、verbs followed by –ing from or infinitive.跟动名词或不定式。
跟不定式作宾语的动词有： decide, refuse, learn, ask, tell, fail, choose, promise, expect, wish, intend, manage, pretend, agree, help, arrange, afford, plan, would, like/ love/prefer, persuade, seem, appear, offer, attempt.

有时，现在分词短语可以替代定语或状语从句，现在分词短语还可以替代and 或but 连接两个并列句。
现在分词短语作状语时，其逻辑主语也必须是句子的主语。
必修五
一、Past participles. 过去分词。过去分词在句中可做形容词或副词，修饰名词，在句中作定语，宾语补足语或表语。在英语书面语中，过去分词短语常用来连接句子的两个部分。这些过去分词短语可以用来在句子中代替reason clause 原因状语从句，time clause, 时间状语从句，conditional clause 条件状语从句。 动词的过去分词形式

一、Noun clause 名词从句
在句子中起名词作用的句子叫名词性从句(Noun Clauses）。名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
一． 主语从句
主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。
1. It 作形式主语和it引导强调句的比较
It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who/whom。例如：
a) It is a pity that you didn‘t go to see the film. 你不去看那场电影真可惜。
b) It doesn‘t interest me whether you succeed or not. 我对你成功与否不感兴趣。 c) It is in the morning that the murder took place. 谋杀案是在早上发生的。（强调句型） d) It is John that broke the window. 是John打碎的窗户。（强调句型） 2. 用it 作形式主语的结构 (1) It is ＋ 名词 ＋ 从句
It is a fact that … 事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) It is ＋ 形容词 ＋ 从句
It is natural that… 很自然… It is strange that… 奇怪的是… (3) It is ＋ 不及物动词 ＋ 从句
It seems that… 似乎… It happened that… 碰巧… It appears that… 似乎… (4) It ＋ 过去分词 ＋ 从句
It is reported that… 据报道… It has been proved that… 已证实… It is said that… 据说… 3. 主语从句不可位于句首的五种情况：
（1）if 引导的主语从句不可居于复合句句首。
（2）It is said /reported…结构中的主语从句不可提前。例如：
正确表达：It is said that President Jiang will visit our school next week. 错误表达：That President Jiang will visit our school next week is said. （3）It happens/occurs…结构中的主语从句不可提前。例如：
正确表达：It occurred to him that he failed in the examination. 错误表达：That he failed in the examination occurred to him.
（4）It doesn‘t matter how/whether …结构中的主语从句不可提前。例如： 正确表达：It doesn‘t matter whether he is wrong or not. 错误表达：Whether he is wrong or not doesn‘t matter.
（5）含主语从句的复合句是疑问句时，主语从句不可提前。例如： 正确表达：Is it likely that it will rain in the evening?
错误表达：Is that will rain in the evening likely? 4. what 与that 在引导主语从句时的区别
what 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。例如：
a) What you said yesterday is right. b) That she is still alive is a consolation
二．宾语从句
宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词 (及物动词) 或介词之后。
1. 作动词的宾语
(1) 由that引导的宾语从句(that 通常可以省略), 例如： I heard that be joined the army. 我听说他参军了。 (2) 由what, whether (if) 引导的宾语从句，例如：
a) She did not know what had happened. 她不知道发生了什么。
b) I wonder whether you can change this note for me. 我想知道你是否能帮我改一下笔记。
(3) 动词＋间接宾语＋宾语从句。例如：
She told me that she would accept my invitation. 她对我说她会接受我的邀请。 2. 作介词的宾语，例如：
Our success depends upon how well we can cooperate with one another. 我们的成功取决于我们之间的合作。
3. 作形容词的宾语，例如：
I am afraid (that) I‘ve made a mistake. 我恐怕我已经犯了一个错误。
注意：that 引导的从句常跟在下列形容词后作宾语：anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以将此类词后的that 从句的看作原因状语从句。 4. it 可以作为形式宾语
it 不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中。例如：
We heard it that she would get married next month. 我听说她下个朋就会结婚了。
5. 后边不能直接跟that 从句的动词
这类动词有allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。这类词后可以用不定式或动名词作宾语，但不可以用that引导的宾语从句。如：
正确表达：I admire their winning the match. 错误表达：I admire that they won the match. 6. 不可用that从句作直接宾语的动词
有些动词不可用于―动词＋间接宾语＋that从句―结构中，常见的有envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如： 正确表达：He impressed the manager as an honest man.
错误表达：He impressed the manager that he was an honest man. 7. 否定的转移
若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。例如：
I don‘t think this dress fits you well. 我认为这件衣服不适合你穿。
三. 表语从句
表语从句在复合句中作表语的名词性从句，放在系动词之后，一般结构是―主语＋连系动词＋表语从句‖。可以接表语从句的连系动词有be, look, remain, seem等。引导表语从句的that常可省略。另外，常用的还有the reason is that… 和It is because 等结构。例如： 1) The question is whether we can make good preparation in such a short time. 2) This is why we can‘t get the support of the people.
3) But the fact remains that we are behind the other classes.
4) The reason he is late for school is that he missed the early bus.
四. 同位语从句
同位语从句就是在复合句中作名词的同位语的名词性从句。
1. 同位语从句的功能
同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，例如： 1) The king‘s decision that the prisoner would be set free surprised all the people. 2) The order that all the soldiers should stay still is given by the general.
2. 同位语在句子中的位置
同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例如： He got the news from Mary that the sports meeting was put off.
3. 同位语从句与定语从句的区别
(1) 定语从句中的that既代替先行词，同时以在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。
(2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。例如：
1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。）（第一个that引导的从句是定语从句，that在从句中作宾语）
2)The news that Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。）（同位语从句，that在句中不作任何成分）
二、Impersonal report structures.非人称转述结构。 转述人们的一般认识或说的话时，我们可以用it+ 动词 （如say，know, believe, claim, suppose, think, fear, predict）被动式结构。
It is said that dolphins are very friendly animals.
It was feared that the plane would crash in to skyscraper. 也可以把有关的人和事放在句首使用这种结构。 Subject+ the passive +infinitive
It was said that the minister had been involved in organized crime. The minister was said that to have been involved in organized crime. 如果转述的动作发生在转述前用完成不定式。
如果转述的动作发生于转述的同一时间，可以用一般的动词不定式。
It is claimed that police officers accept bribes. Police officers are claimed to accept bribes. Get ahead 取得成功，取得进步。 in the absence of 缺乏，不存在。
Take the form /take a form of 以…的形式出现，存在。
Stay dedicated 保持，维持。Stay 是系动词和形容词连用。
stay seated 坐着别动
hold the key to …的关键， be associated with 联系 三、The future 将来时
除了，will/may/might +不带to 的不定式，现在进行时，be going to 结构和一般现在时之外，可以用下列时态和动词将来： 1.Future perfect将来完成时：
用将来完成时谈论在将来某个特定的时间之前完成的活动。 He will have written two books by next summer. 2.Future continuous: 将来进行时
用将来进行时谈论在将来某个特定的时间进行的活动。 I‘ll be working all evening so I won‘t be able to see you. 3.Time clause:时间状语从句
在when, as soon as, until, before, 和after 引导时间状语从句中，表示将来的时间时，不用will 用一般现在时。
When you got home, you will receive good news. 四、Pronouns 代词
代词是句子中代替名词的词。这样反复地过于频繁地使用名词。英语中有下列代词： 人称代词：主格代词：I, you, he, she, it, we, they, 宾格代词：me, you, him, her, it, us, them.
不定代词：someone， something, anything, nobody, nothing, etc. 所有格代词：mine, yours, his, her, their, ours
反身代词：myself, yourself, himself, herself, itself, ourselves, yourselves, themselves. 关系代词：who, which, that, whose, whom. One VS you
泛泛谈论人物时，用one 和you 其意思是任何人，one 用在正式的语言中，而you 用在非正式语言中。
One has got (or you have got) more chance of finding an interesting job abroad nowadays.
五、Conditionals and mixed conditionals 条件句和混合条件句。条件句有四种：即：零条件句。第一条件句，第二条件句和第三条件句。
*按习惯分为两种，真实条件句和非真实条件句。这里的前两种属于真实条件句，后两种属于非真实条件句。
所谓混合条件句是指混合的条件句中含有不同的条件结构。用混合条件句谈论：想象的过去事件可能对现在的影响。
If he had broken the record, he would be famous now. Form: If + past perfect, would + infinitive ,without to (as in 3rd conditional) (as in 2nd conditional)
非真实条件句常常是想象中的现在状态，可能对过去有影响。 If she didn‘t speak a few languages, she wouldn‘t have got that job. Form: If +past simple, would +perfect infinitive
(as in 2nd conditional) (as in 3rd conditional)
If he was/ were (2)a more skillful player, he would have second(3) more points. May/might/could/will/have to/ must/ can /need.
六、Modal verbs and Expressions 情态动词表达法。 1.情态动词用来谈论义务和需要： I had to walk ten mils to get home. 2.谈论允许和禁止： We mustn‘t disturb them. 3.谈论无必要：
We didn‘t have to pay for the beer, it was free. You needn‘t worry, everything will be all right. 4.谈论能力：
My little daughter can sing and dance. I could talk when I was two. 5.谈论可能性：
I can‘t go through to them, the live is busy. John couldn‘t see us in the crowd. 6.猜想和猜测：
He will be cooking lunch now.
They must have found out about the article. He might be Russian. He could be at the library. 7.预测：
He will be late, as usual.
They might win, if they try hard. 8.做决定：
I will talk to Jim about it. I won‘t go there.
Didn‘t need VS needn‘t
Didn‘t +(不带to 的)不定式结构表示某人不用做某事，因为没有必要。 He was so rich he didn‘t need to worry about money.
Needn‘t +完成式的不定式结构表示某人做了某事尽管是不必做的。 We needn‘t have bought any food to the party –there was plenty already. 七、Verb patterns: ―ing‖ form. And infinitive D动词ing 和不定式used to, be used to and get used to .
1. 我们用used to +不带to 的不定式谈论过去的状态或经常进行的活动，这种状态和活动现在已终止。
We used to go camping a lot.
2.be used to +动词 ing 形式或名词表示我们队某事很熟悉。 We‘re used to getting up early.
3.get used to + -ing form 形式或名词描述熟悉某事的过程。 We got used to eating rice when we lived in Asia.

7.verb +preposition +ing form 动词+介词+动词ing形式。 下列动词可用于此结构：accuse of , succeed in, etc.
在下列情况下，在间接引语中不用改变原动词的时态。
主句动词时一般现在时时：I feel feverish – She says she feels feverish. 所报道的仍是真理时，如：一般事实。
Kangaroos live in Australia. ---- The teacher said that kangaroos live in Australia. 对进行报道那一刻而言，所报道的内容仍属于将要发生的事情时。 二、The Passive被动语态 下列情况下使用被动语态： 不知道动作的执行者时。
要关注的事动作的本身而不是动作执行者时。 要特别关注动作执行这时， 要避免句子主语太长时。
被动语态主要用于正式的表达和书面语中，是非常典型的报刊和报道用语，除了动词时态的被动形式外，还有其他被动形式：
不定式的被动语态： It‘s nice to be taken seriously.
动名词的被动形式：We all enjoyed being praised by the teacher.
不定式的被动完成形式：The train may have been delayed by the storm. 三、Emphatic structures: inversion and ―it‖ cleft sentences. 强调结构，倒装句和分裂句―it‖
把否定词（如seldom）置于句首形式倒装表示强调，即用疑问句的语序。这样的强调句通常用于正式的书面语中。
He was never known anything like it. Never has he known anything like it. 倒装形式的强调也可以用于对过去事实进行假设的条件中。
注意形成倒装时，要将if去掉。这样的倒装句常见于正式和非正式的表达中。 If I had known they were in town, I would have phoned them. = Had I known they were in town, I would have phoned them.
在正式和非正式的表达中，可以用下列结构对某些词语进行强调。 It‘s money that he‘s interested. 四、表达完成的动词形式

动词ing形式的完成式： I remembered having met the man long time ago. 五、Persuasion说服
在正式的英语书面语及非正式的英语口语中，常用不同方式来告知人们，我们认为他们该做什么。 英语书面语
在进行正式书面表达时，下列表达方式可以强化―建议‖ Should +不带to 的不定式 Ought to +不带to 的不定式
Demand/insist/suggest + (that) +subject +should do something (that) +subject +present tense (主+现在时态) +（that）+subject + subjunctive (主语+虚拟语气) （same form as infinitive） 英语口语
跟熟人交谈时，用下列表达方式可以使―建议‖听上去不那么强硬，具有试探性
If I were you , I‘d + infinitive without ―to‖ 不带to 的不定式，是建议听上去语气略强时，用些列结构：
I think you should +不带to 的不定式 I think you ought to +不带to 的不定式
用下列表达方式可以强硬地对某人批评，责怪或提出建议。使用这样的表达方式的人常常具有权威性，如教师对学生，家长对孩子。 It‘s about time +主语+一般过去时
I‘d (I would ) rather +主语+一般过去时
You‘d better (had better) + 不带to 的不定式
You‘d better 也可以用在和朋友交谈时，表示鼓励或说服。
I‘d sooner you +一般过去时，这种表达方式现在已不多用。而改用―I‘d rather ‖ 这两种结构后面通常用动词的否定形式。 六、Persuasion
在正式的和非正式的语言表达中，常用不同的方式来告知人们他们该做什么。 1，在正式用语中，用下列结构：ought to +不定式
Demand /insist /suggest that +主语+should /do something 一般现在时、虚拟语气（同不定式形式）
It‘s high time +主语+一般过去时（正式用法通常为权威人士使用） 2，在非正式用语中，用if I were you, I‘d +不定式。 I‘d （would）rather +主语+一般过去时 You‘d better /had better +不带to 的不定式 It‘s about time +主语+一般过去时
（除非用于密友或家长谈话，否则这种表达方式显得生硬粗鲁）
I‘d sooner+ 主语+一般过去时（这种表达方式相当正式，说话人带有明显的偏爱） 3，在进行正式的和非正式语言表达时，用should +不定式
