时态和语态

（一）时态

1.一般现在时（1）表示经常性、习惯性的动作；1.I get up at 7 o' clock in the morning. 2.I leave school for home at 6 every evening. （2）客观真理，客观存在，科学事实；1.The teacher told us: the earth moves around the sun. 2.Shanghai lies in the east of China.

2. 一般过去时：两种变化形式：在动词后加ed或不规则变化的动词；在确定的过去时间里所发生的动作或存在的状态：常用时间状语：yesterday, last week, an hour ago, the other day, in 1982等；Did you go to Shanghai last week?

补充：used to/be used to （1）used to + do："过去常常"，表示过去习惯性的动作或状态，但如今已不存在；Mike used to take a walk. （2）be used to + doing： 对……已感到习惯，或"习惯于"，to是介词，后需加名词或动名词；1.Mike is used to taking a walk.2. He is used to taking a shower with cold water. （3）be used to do：被用来做……Leaves are used to fight enemies in Kong fu movies as the weapons.

>- Your phone number again? I _A__ quite catch it.

>- It's 69568442.

A. didn't B. couldn't C. don't D. can't

答案A. 本句虽没有明确的时间状语，但从语意上看出，在听的时候没有听懂这个动作发生在过去，因此应用过去时。

一般过去式和过去完成时的对比：（1）过去完成时：过去的过去；Before I came to Beijing, I had stayed in Shanghai. ① 一个句子里有两个谓语动词，一个发生在前，一个发生在后，发生在前的用一般过去时，发生在后的用过去完成时；When the police arrived, the thieves had run away. ② 表示意向的动词，如hope, wish, expect, think, intend, mean, suppose等，用过去完成时表示"原本…，却未能…"1.We had hoped that you would come, but you didn't. 2.We had thought that he would take part in the competition，but he didn't.

③ 虚拟语气：若虚拟的现象与过去事实相反，则用过去完成时；If you had come to my birthday party, you would have seen Yaoming.（虚拟语气中可以用had+过去分词，表示对过去事实的虚拟） 3. 一般将来时 （1）shall/will, shall用于第一人称，常被will 所代替;Which paragraph shall I read first？ （2）be going to +不定式，表示将来；表示要发生的事情有了预先的计划、准备或有迹象表明要发生；1.What are you going to do tomorrow? 2.What will you do this afternoon?（will表示纯粹的将来）

（3）be +不定式：表将来，按计划或正式安排将发生的事；We are to/will discuss the report next Saturday. （4）be about to +不定式：意为马上做某事，后面不可以接时间状语；He is about to leave for Beijing.

注意：（1）一般现在时有时也可表将来；The train leaves at six tomorrow morning. ① 趋向性动词come, go, arrive, leave, start, begin, return的一般现在时表将来，主要用来表示在时间上已确定或安排好的事情。When does the bus star? It stars in ten minutes. ② 在时间或条件句中，用一般现在时表将来；I'll write to you as soon as I arrive in Beijing.

（2）现在进行时也可表将来：通常用于口语，翻译为打算……；come, go, start, arrive, leave, stay等词可以用进行时表将来；

4. 现在完成时：现在完成时用来表示之前已发生或完成的动作或状态，其结果对现在造成影响。 （1）过去发生的动作发生到现在，刚刚完成； （2）从过去发生的动作，发生到现在，刚刚告一段落，但是后面会继续发生；1.I have just finished my homework. 2.It has rained for 3 days.

过去时与现在完成时的区别： （1）过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。1.I came to Beijing in 1995.2.I have stayed in Beijing since 1995. （2）过去时常与具体的时间状语连用，而现在完成时通常与段的时间状语连用，或无时间状语。一般过去时常用时间状语：yesterday, last week，…ago, in1980, in October…（具体时间）；He had dinner with me yesterday.现在完成时常用时间状语：for, since, so far…（长期的段时间）I have played basketball for 3 hours.

（3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live, teach, learn, work, study, know；He got married two years ago.过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等；I have lived in Beijing for 10 years.

用于现在完成时的句型

（1）It is the first / second time…. that…结构中的从句部分，用现在完成时。

It is the first time that I have visited the city.

It was the third time that the boy had been late.

（2）This is the… that…结构，that 从句要用现在完成时.

This is the best film that I've (ever) seen. 这是我看过的最好的电影。

This is the first time (that) I've heard him sing. 这是我第一次听他唱歌。

典型例题：>Have you ____ been to our town before?

>No, it's the first time I ___ here.

A. even, come B. even, have come C. ever, come D. ever, have come

答案D. ever意为曾经或无论何时，反意词为never，此两词常用于完成时。 This is the largest fish I have ever seen. It is / was the first time +that-clause 的句型中，从句要用完成时。

since和for的用法： since 用来说明动作起始时间，for用来说明动作延续时间长度;1.I have lived here for more than twenty years.2.I have lived here since I was born. for后面多接一段时间，而since后面则接一个时间点，若since后面也出现时间段，则在时间段后加ago；I have lived here since twenty years ago.错句：I have worked here since many years.

since句型：It is +一段时间+ since从句，since从句要用一般过去时；1.It is two years since I became a postgraduate student.2.It is three years since I joined the army.

5. 进行时态：一般进行时，过去进行时，将来进行时；6. 现在完成进行时：have/has+been+doing：现在完成进行时和现在完成时的区别：1.It has rained for 3 days. 2.It has been raining for 3 days.现在完成时不强调某一动作在某段时间内持续发生；现在完成进行时表示某一时间段内某动作持续发生。1.I have been learning English for 5 years.2.I have been learned English for 5 years.

（二）语态 一般 进行 完成 现在 am/is/are+过去分词 am/is/are+being+过去分词 have/has+been+过去分词 过去 was/were+过去分词 was/were+being+过去分词 had+been+过去分词 将来 will+be+过去分词 被动语态基本形式：be+动词过去分词；1.Forest have been cleared.3.They were given a warm send off.3.Their wedding will be held in the church.不强调施动者，而只强调受动者；The book was written 20 years ago.

1. The commission has already cleared the way for overseas firms to use IFRS when doing business or listing securities in America证券委员会已经为海外公司在美国做生意或者上市时候使用国际财务报表准则扫清了道路。

2. create something from scratch.白手起家

四、真题举例：

1.Despite the hardship he encountered, Mark never______________(放弃对知识的追求).

分析：give up/abandon/quit the pursuit of knowledge或者gave up/abandoned/quit the pursuit of knowledge

2.The study shows that the poor functioning of the human body is_______(与缺乏锻炼密切相关) 分析：is+doing/形容词：be closely related to：the lack of exercises：缺乏锻炼；is closely related to the lack of exercises

3.Through the project, many people have received training and______________(决定自己创业) 分析：have received：现在完成时；decided to：决定；创业：launch their own enterprise；decided to launch their own enterprise

4. I can’t boot my computer now. Something must____（一定出了毛病）with its operating system.分析：出了毛病：out of control；Something must be out of control/wrong with…

五、定语从句： eg：I know the girl. The girl comes from Beijing. I know the girl who comes from Beijing.步骤1.找到两个句子中相同的名词； 2.将两个名词中的一个进行替换，若是人，用who替换；若是物，用which替换；that既可以指人，又可以指物； 3.将who 或which引导的句子放在相同名词之后； eg：I like reading books. The books were written by O Henry. I like reading books which were written by O Henry.

eg：I planted a tree. The tree is taller than the house. The tree which I planted is taller than the house.

1. who/that/which所引导的句子必须放在相同名词之后； eg：The teacher prized the boy. The boy is my neighbor. The boy who the teacher prized is my neighbor.

eg：This is the book. You are looking for the book. This is the book which you are looking for. eg：This is the book. You are interested in the book. This is the book which you are interested in.

2. 谓语动词（结构）和后面的介词有两种关系：关系紧密＆关系疏远； 关系紧密：谓语结构和介词合成在一起，联系紧密，不可分割，一旦分割意思就会发生改变；look for, be interested in , look after, look at 定语从句中如果谓语结构和介词关系紧密，则介词必须保留在谓语结构的后面，不能做任何位置的改动；如果谓语结构和介词关系疏远，介词一般提到which/who/that的前面； eg: This is the book which you are looking for. This is the book which you are interested in. This is the book in which you are interested. This is the book which you asked for.

3. 关系代词和关系副词： eg：Beijing is the place. I was born in the place. Beijing is the place which I was born in. Beijing is the place in which I was born. 定语从句中，如果介词+which表示地点，则可以用where替换； Beijing is the place where I was born. eg: I can't forget the day. I join the army on the day. I can't forget the day which I join the army on. I can't forget the day on which I join the army. I can't forget the day when I join the army.

判断： This is the mountain village where I visited last year. This is the mountain village in which I visited last year. This is the mountain village which I visited in last year.正确： This is the mountain village which/that I visited last year.

4. 判断关系代词和关系副词的方法：（1）不管是关系代词还是关系副词，都取决于从句中的谓语动词。若该谓语动词为及物动词，则一定使用关系代词；若该谓语动词为不及物动词，且其后没有介词，则一定使用关系副词； eg：I will never forget the days when I worked together with you. 错：I will never forget the days when I spent in the countryside. 对：I will never forget the days which I spent in the countryside.

（2）通过判断先行词在定语从句中的成分 eg：Is this the museum （that ） you visited a few days ago?（the museum：充当visit的宾语）Is this the museum ( in which/where ) the exhibition was held?

关系代词：前面句子里的先行词也要在后面的句子里充当主语或者宾语的成分；介词+which，恰好表示时间和地点，可以替换成when，where这样的关系副词；

5 限定性定语从句和非限定性定语从句

(1)非限定性定语从句：先行词（即名词）后有一个逗号；In our school，there were 8 foreign teachers who come from Australia.（限定性定语从句）In our school，there were 8 foreign teachers，who come from Australia.（非限定性定语从句）限定性定语从句：定语从句和关系词关系非常紧密，删掉定语从句后，整个句子意思会改变；非限定性定语从句：定语从句和关系词关系不是很紧密，删掉定语从句后，整个句子意思不会改变，定语从句只起到补充说明的意义； eg：This is the house which we bought last month.

This is the house, which we bought last month.

（2）非限定性定语从句：

①先行词是前面的整句话； eg: He won the first place in the competition, which is out of our expectation. We will spend the Spring Festival in Guangzhou, which was decided last year.

This is the house, which we bought last month.

② 非限定性定语从句：which引导非限制性定语从句只能放在后面，as则只能放在句子前面； eg: Smoking is harmful to our heath, which we know. 错：Smoking is harmful to our heath, as we know. 对：As we know, smoking is harmful to our heath. eg：Alice received an invitation from her boss（ D ） came as a surprise . A. It B. that C. as D. which

(3)that和which的区别：①什么时候不能用that，只能用which：非限定性定语从句中，即逗号之后:.The tree, (which) is 400 years old, which is very famous here. (不能用that);介词后面不能用that，只能用which :We depend on the land, from which we can get our food.(不能用that)

但有一种情况：in that：表示因为；In respect that behind the prosperous of contemporary art market is the collusion and cooperation among galleries, auction houses, collectors and so on因为在当代艺术市场火暴的背后是画廊、拍卖行、收藏家等群体的共谋与合作

（4）什么时候不能用which，只能用that：① 前面的先行词是不定代词，包括all，anything，nothing，the one， much，little等;1.Have you taken down everything that Mr. Lee has said? 2.Of all his books this is the one I like best在他全部书籍中间，这本书是我最喜欢的3.In salary negotiations, the one who mentions money first loses在薪资协商中，第一个提到钱的人就是输家A realistic appraisal of the task ahead is therefore timely, and a businesslike approach is the one most likely to succeed因此，提前对这项任务进行切实可行的评估是适时的，而有条不紊的方法则最可能成功Sounds like "secure attachment" is the one to look for看来我们真正需要的应该是安全型依恋If you cannot win, make the one ahead of you break the record就算你不能赢，也要努力使你前面的一个人打破记录Further said that his invention on the one hand to realize the value of life更进一步说，他的发明一方面实现了自己的人生价值Because confidence includes so many of these other characteristic, it may just be the one major thing women look for in a man因为自信包含了如此多的其它因素，所以是女人从男人身上要寻找的一件很重要的东西② 如果先行词中出现了the only, the very等；This is the only way that we can think out. Our marriage was a cover from the very beginning我们的婚姻从一开始就是为了掩饰Some people think the very nature of virtual worlds can inspire bad behavior一些人认为虚拟世界的性质将会激发一些恶意行为③ 如果先行词中出现了序数词和形容词最高级；This is the best film that I have ever seen.④ 如果先行词中即有人，又有物；They are talking about the school and the teachers that they visited yesterday.

例：Medical researchers are painfully（费力地）aware that there are many problems (他们至今还没找到答案）. They haven’t found solutions/answers to these problems. There are many problems which they haven’t found solutions/answers to.

例：（与我成长的地方相比），this town is more prosperous and exciting. Compared with the place in which/where I grew up,

例：（听到他告诉我的消息），I couldn’t help laughing．Hearing the news which/that he told me,

例：Career experts say that one of the ways job seekers can stay safe while using the Internet to search out jobs is to conceal（隐藏） their identities.

六.名词性从句

名词性从句：主语从句、宾语从句、补语从句及同位语从句；定义：在句子中起名词作用的句子，且在句子中能担任主语、宾语、表语、同位语、介词宾语等成分；

（1）同位语从句：对前面名词的进一步解释 eg：I know the man, the president of the New Oriental School. 英语中的简单句：陈述句、一般疑问句、特殊疑问句。 eg：He is a student. Are you a student? Who is a student? 同位语从句：关系词不再和前面的名词有关系，而是取决于后面的从句； eg：I know the fact. He is a student. I know the fact that he is a student.

eg：I have a question. Are you a student? I have a question whether you are a student. I have a question who is a student.

I have no idea when he will come back.

注意：从句仍然接在名词之后，名词有可能为answer，belief，concept，explanation，fact，hope, message, news, promise, prove, question, thought等，后面可以接同位语从句；形式：名词+从句；连接词取决于后面的从句是什么样的形式；1.如果是陈述句，直接加that引导；I know the fact that he is a student.；2.一般疑问句：先把一般疑问句变成陈述句语序，然后在其前加上whether或者if；I have a question whether you are a student.3.特殊疑问句：直接保留特殊疑问词，后面的句子变成陈述句语序；I have a question who is a student. eg： The news soon spread the whole school. They had won the game. The news that they had won the game soon spread the whole school. The news that they had won the game came. News came that they had won the game.

eg：Information has been issued. More middle school student will be admitted to universities. Information that more middle school student will be admitted to universities has been issued. Information has been issued that more middle school student will be admitted to universities.

eg：The question was answered by the family doctor. Whether we should send for an specialist.The question whether we should send for an specialist(专家) was answered by the family doctor.

同位语从句的形式和定语从句的形式相似，两者最大的区别在于同位语从句的功能在于对前面的名词进行进一步的解释，定语从句的功能在于对前面的名词进行进一步的修饰和限定；

1.如果关系词为weather，how, what, 一定是同位语从句；2.如果名词前的关系词为when, where, why，若when前面的名词是地点，where前面的名词是时间，why 前面的名词是原因，那么一定是定语从句；若when, where, why前面不是地点、时间和原因，那么是同位语从句；3.如果关系词为which，则通过中文翻译进行区分；若which能翻译成哪一个，则一定是同位语从句，若不能，则为定语从句；4.如果关系词为that，则需要对句子进行成分分析来判定；如果that在句子中充当成分，则是定语从句，否则即为；

eg：The suggestion that she should stay in the room is good.（同位语从句） The suggestion that she has given in the meeting is good. （定语从句）

例：The fact that ordinary citizens are now starting to think seriously about the nation's moral climate, says this ethics professor at the University of Chicago, is reason to hope that new ideas will come forward to improve it.

(2) 宾语从句:从句部分的连词取决于从句是一般疑问句、特殊疑问句还是陈述句； eg：We must find out who did all these. I want to know whether he will come. I hope that he will come.

① 宾语从句的时态：如果宾语从句前的动词是过去式，则宾语从句的时态应相应变成过去时态；Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton（骨骼） was found near Great Salt Lake.如果宾语从句是客观事实或真理，不管宾语从句前的动词时什么时态，宾语从句都用一般现在时；The teacher told us that the earth is round.

② 宾语从句后接陈述句，用that引导，则that一般可以省略；I think（that）you are right.

③ 宾语从句如果谓语动词是doubt，后面接的一般疑问句通常用weather或if引导；1.I doubt whether he is telling the truth.2.

九 从句的复习

复合句：定语从句、名词性从句、状语从句。(1)定语从句：

1. that，which，who的使用。一个句子当中有两个相同的名词，将其中的一个名词进行替换，如果是人，用who；如果是物，用which；that既可以指人又可以指物。 2. 谓语动词（结构）和后面的介词有两种关系：关系紧密和关系疏远；定语从句中如果谓语结构和介词关系紧密，则介词必须保留在谓语结构的后面，不能做任何位置的改动；如果谓语结构和介词关系疏远，介词一般提到which/who/that的前面； 介词加which正好表示时间，可以表达成when；表示地点时，可以表达成where；表示原因时，变成why； 3. 限定性定语从句和非限定性定语从句。限定性定语从句：定语从句和关系词关系非常紧密，删掉定语从句后，整个句子意思会改变；非限定性定语从句：定语从句和关系词关系不是很紧密，删掉定语从句后，整个句子意思不会改变，定语从句只起到补充说明的意义；

（2）非限定性定语从句：He won the first place in the competition, which is out of our expectation.（As is out of our expectation, he won the first place in the competition）

(2)名词性从句：主语从句、宾语从句、表语从句及同谓语从句；形式：名词+从句；连接词取决于后面的从句是什么样的形式；如果是陈述句，直接加that引导；一般疑问句：先把一般疑问句变成陈述句语序，然后在其前加上weather或者if；特殊疑问句：直接保留特殊疑问词，后面的句子变成陈述句语序；定义：在句子中起名词作用的句子，且在句子中能担任主语、宾语、表语、同谓语、介词宾语等成分；Yuminhong, the president of New Oriental School.

(3)状语从句:两个独立的句子中间用一些含义不同的连接词连接；状语从句用来表达两个句子之间的逻辑关系；分成原因状语、条件状语、结果状语、时间状语、地点状语、让步状语、目的状语、比较状语、方式状语等九大类型；

定语从句:名词+关系词+从句，关系词的用法取决于名词的问题； 名词性从句：同谓语从句：名词+关系词+从句，关系词跟后面的从句有关系，如果是陈述句，直接加that引导；一般疑问句：先把一般疑问句变成陈述句语序，然后在其前加上weather或者if；特殊疑问句：直接保留特殊疑问词，后面的句子变成陈述句语序； 宾语从句：动词+关系词+从句；表语从句：系动词+关系词+从句；主语从句：关系词+从句+谓语动词；名词性从句，其关系词的来源取决于后面的从句的性质。 状语从句：完整句子1+逻辑关系词+完整句子2；

如何区分定语从句和同谓语从句：whether，what，how接在名词后面一定是同谓语从句；关系词是when ，where，why如果前面不是时间、地点、人物，那么是同谓语从句；如果是的话，则为定语从句；如果见到which的话，which在句中翻译成“哪一个”，就是同谓语；翻译不成“哪一个”就是定语从句；that 就是看它在句中是否充当成分，如果充当成分就是定语从句；不充当成分就是同谓语从句；

1.Whether the plan is feasible remains to be proved.（主语从句）是否这个计划是可行的仍然值得去考证。

2.I worry about whether he can pass through the crisis of his illness.（宾语从句）我担心他是否能度过疾病的危险期。

3.They are investigating the question whether the man is trustworthy(可靠的).（同谓语从句）

5.While（让步状语从句）even the modestly educated sought an elevated tone when （时间状语从句）they put pen to paper before the 1960s, even the most well regarded writing since then has sought to capture spoken English on the page.在20世纪60年代之前，当人们伏案写作的时候，即使那些接受教育不多的人也会追求一种高雅的风格，但是从那以后，即使是那些令人敬仰的文学作品也在追求一种口语的风格。

6.About 45% of the world's population lived in the climate zone where mosquito transmit disease.全球45%的人口都生活在这样的一个区域，这个地方的蚊子会传播疾病。

7.He was an Asian American（who was）raised in a household where respectful zones in authority was show by averting your eyes.（定语从句）他是一个亚裔美国人，在他生长的环境当中，避免与有权威的人对视是对对方尊重的一种表现。

Most likely, you will believe that this will take more time than you actually have and you will end up staring blankly at the pages as the deadline draws near.（分析）as引导的是时间状语从句，译为“随着.....”（译文）很有可能，你会相信这比你实际用的时间要长，随着最终期限的临近，你就会以茫然地盯着纸这样的方式而结束。It is… that … 形式主语，强调句型强调句型：无指代关系，也无实义，去掉后剩余的词仍能单独组成一个完整的句子。It is in 1998 that I came to Beijing.
