英语时态总结
时态(Tense)是表示行为、动作和状态在各种时间条件下的动词形式。因此,当我们说时态结构的时候,指的是相应时态下的动词形式。
英语时态分为16种:一般现在、一般过去、一般将来、过去将来时,以及这四者的进行时、完成时和完成进行时。在这里,我们重点讲解一下最常见的11种时态的用法和注意事项。
1. 一般现在时:小学就开始学这个,大家都会吧,有几点强调一下我们就走。
A) 表示现在发生的动作、情况、状态和特征。If it is not too much trouble, I would like a cup of tea.
B) 习惯用语:这个要在平时自己积累,因为习语太多,我不做过多解释。
Ie: Believe it or not, his discovery had created a stir in scientific circles.
口语中常说believe it or not,意思是:“信不信由你”,“我说的是真的”。believe it or not是一个固定说法,相当一个插入语,短语中的believe没有词形变化。这点要注意,以后会教你们动名词的用法,到时候会牵涉到主语的问题。
C) 经常性、习惯性动作。
Ie:He always helps others. (他总是帮助别人。)
D) 客观事实和普遍真理。尤其要注意,如果前后文不是一般现在时,则无法保持主句、从句时态一致.ex: He said that the sun rises in the east.这个句子要注意,到了以后的定语从句经常会有这样的问题,具体细节到时候在说,不过你们要先有这样的概念:客观事实无论谓语的时态是什么都用一般现在时。
E) 表示一个按规定、计划或安排要发生的动作,(仅限于某些表示“来、去、动、停、开始、结束、继续”等的动词 )可以与表示未来时间的状语搭配使用。常见的用法是:飞机、火车、轮船、汽车等定期定点运行的交通方式。
ex: When does the plan leave?这个句子注意一下,就是这么用的,有人会注意到这样的问题: The plane leaves at 3 o’clock this afternoon.为什么不用将来时,对了,很奇怪,但就是这么用的。
F) 在时间和条件状语从句里经常用一般现在(有时也用现在完成时)表示将来事情。
Ie: When you finish the report, I will have waited for 3 hours.(完成时,往下看会出现)
2. 现在进行时(be doing) 的用法:上了初一就教这个吧,比一般现在还简单。表示现在正在做的动作,但要注意有的动词不能用于进行时,这类词称为短暂性动词,如,open, borrow等等,在完成时态常常会碰到,平时要注意积累。
3. 现在完成时(have done):重要考点,初二以后几乎都是完成时态。
A) 表示动作到现在为止已经完成或刚刚完成。
ex: I have just finished my homework.
B) 表示从过去某时刻开始,持续到现在的动作或情况,并且有可能会继续延续下去。此时经常用延续性动词。时间状语常用since加一个过去的时间点,或for加一段时间,或by加一个现在时间。这里联系进行时,他们都一样,不能用短暂性动词,★★★☆☆考点。
C) 表示发生在过去,但对现在仍有影响的动作或情况。通常用点动词,如:arrive, begin, find, give, lose等。
例:John has broken his left leg.(约翰摔断了左腿。)
注意:
A) 现在完成时是联系过去和现在的纽带。现在完成时和过去时的区别在于:现在完成时强调动作的动态,或受动态的影响,是动态的结果,对现在有影响;过去时只表示过去的某个具体时间里发生的动作,与现在没有联系。
例:He worked in that hospital for 8 years.(他曾经在那家医院工作了8年。这只是讲述一个过去的事实,他现在已经不在那家医院了。)
He has worked in that hospital for 8 years.(他已经在那家医院里工作了8年。表示他从过去开始工作,一直工作到现在,现在仍在那家医院工作。)
B) 因为含有for加一段时间或since加一个时间点这样的时间状语的完成时,有动态和延续性的特点,所以不能使用终端动词或瞬间动词。
例:My sister has been married for 5 years.(过去分词做表语表示状态,可以延续)
My sister has married. Don't disturb her.(终端动词)
C) 在"this is the first/ second/ third…… time that……"句型里要求用完成时。
例: This is the second time that the procts of our company have been shown in the International Exhibition. (这是我公司产品第二次参加国际展览会。)
D) 句型"It is/ has been……since"所使用的两种时态都正确。
例:It is/ has been 10 years since I last saw him.(从我上次见到他以来已经10年了。)
E) 在"no sooner than"、"hardly/ scarcely ……when"、"before"、"prior to"等句型中,主句要求完成时。
例:I haven't met that professor prior to today.(以前我从未见过那位教授。)
4. 现在完成进行时(have been doing):和现在进行时很像
1) 用法:表示某一动作开始于过去某一时间,延续或重复地出现至今,或将继续延续至将来。
例:We have been working on this project for over a month now.(到目前为止,我们一直在处理那个项目,已经花了一个多月时间了。)
2) 注意事项:与现在完成时相比,现在完成进行时更强调:在从过去到现在的时间里,动作或状态一直持续或一直反复出现。
5. 一般过去时
A) 表示过去某个时间发生的动作或情况。
ex:I went to Beijing last year.
B) 表示过去习惯性动作。特别是由would/ used to do表达的句型,本身表示的就是过去时。
ex: I used to live here.(注意used to 和be used to 的区别,used to表过去常常,be used to 表示习惯于,前者to是不定式符号,后者则是介词,后接名词、动名词、代词)
C) 有时可代替一般现在时,表达一种婉转、客气、礼貌、商量的语气。
ex: Would you mind my sitting here?(您介意我坐在这里吗?)
Could you pass me the pen?
注意:
A) 注意时间状语的搭配。一般过去时的时间状语应该是表示过去某个时间的词或词组,如:yesterday, last month, in 1999, two days ago等,绝对不可与recently, in the past 10 years, this month等连用,因为这样的时间状语都与现在有关系,应该用现在完成时或一般现在时。注意,到了初二将会是★★★★☆考点,不会不行,逃不了的,几乎每次都考。
B) used to do的否定形式和疑问形式很特别:你怎么写都正确。以否定形式为例:used not to do, didn't used to do, didn't use to do都对。
6. 过去完成时(had done)
用法:表示在过去的某个时间或动作以前已经发生的动作或已经存在的状态。就是我们常说的:表示"过去的过去的动作或状态"。
画一条时间轴过去完成__●_一般过去_◇_一般现在___○______
2) 注意事项:“过去的过去”这种逻辑关系常通过上下文体现出来,而不一定受某个时间状语的限制。
ex: There had been some one in our room just now, because I noticed a burning cigarette end on the floor when we opened the front door.
7. 过去将来时(would/ should do) 表示从过去的某个时间看将要发生的事。其实和将来时没什么区别啦。
ex: I said on Thursday I should see my friend the next day.宾从、直引经常碰到这样的例子,注意。
8. 过去进行时(was/ were doing)
A) 表示在过去一个比较具体的时间正在发生的动作。
ex: I was doing my homework at this time yesterday.
B) 如果when, while这样的时间状语引导词所引导的主从句之一是一般过去时,则另一个句子常用过去进行时。
ex: I was washing my hair when you knocked at the front door.
9. 一般将来时
A) 基本结构是will / shall do。古英语认为will用于第二、三人称,shall用于第一人称,但后来没做硬性规定,will比较常用。I will be home at 10.
B) 有些动词,如:arrive, be close, come, do, done, go, have, leave, open, play, return, sleep, start, stay等,用于一般进行时,并且通常与一个表示将来时间的时间状语连用,可以表示将来时。初一接触比较 多的是be going to,后面的包括will/shall到了后来才出现,其他如sleep很少见,初中阶段我几乎没见过sleep这么用的, leave, come, arrive也常见
ex: My mother is coming to visit me next week and is staying here until May.
C) 表示“即将、正要”时,可用be about to do。强调近期内或马上要做的事,后常与when连用。ex: I was about to speak when you interrupted me.
D)"be to do"的5种用法:
a) 表示“按计划、安排即将发生某事或打算做某事”。
例:She is to be seen in the lab on Monday.(星期一你准会在实验室见到她。)
b) 该做或不该做的事情(语气上接近于should, must, ought to, have to),表示一种命令、规劝性语气。
例:You are to go to bed and keep quiet, kids. Our guests are arriving in less than 5 minutes.(孩子们,你们必须 上床睡觉,不准吵闹。我们的客人5分钟之内就要到了。)
c) 能或不能发生的事情(接近can, may)
例:How am I to pay such a debt?(我怎么可能还得起这么大的一笔债呢?)
d) 不可避免将要发生的事情,后来将要发生的事情。
例:I assure you that the matter _______ as quickly as possible. Have a little patience.
A. will be attended B. will be attended to
C. is attended D. is attended to
will be attended to关键的一点是:attend表示“处理,解决”时是不及物动词,必须与to连用。另外,从上下文看,事情显然尚未解决,所以应该用将来时的被动语态。答案是B。
A) is to be B) can be C) will be D) has been
答案是A) is to be。全句的意思是:“如果要避免食品短缺,就必须作出更大努力来增加农业产量。”
E) 同样可以表示“正要、将要”的意思的句型是be on the point of doing。 The coach is on the point of giving up the game because our team has been scored 7 points.
注意:
在 以if, when, as long as, as soon as, after, before, in case, until, unless 等连词以及具有连词作用的副词(immediately, the moment, directly)等引导的状语从句,一般用现在时代替将来时。强调 延续性或动态时,可用完成时。
例:I hope his health will have improved by the time you come back next year.(我希望到明年你回来的时候,他的身体已经好多了。)
10. 将来进行时(will be doing) 调在将来的某个具体时间正在发生的动作或事情。
ex: Don't worry, you won't miss her. She will be wearing a red T-shirt and a white skirt at that time.
11. 将来完成时(will have done) 表示从将来的某一时间开始、延续到另一个将来时间的动作或状态,或是发生在某个将来时间,但对其后的另一个将来时间有影响的动作或状态。就好象把现在完成时平移到时间轴的将来时时段一样。其用法从和过去及现在有关,变成了和将来及将来的将来有关。
eg: It is reported that by the end of this century the people of Chinese will have increased by 2 billion
自己看一下把!!!!!!!!!!!!!

Ⅱ. 几种常见时态的相互转换
英语中的几种时态在一定情况下可以互相转换,以下是几种常见的转换形式:
一、一般过去时与现在完成时的转换
在现在完成时中,延续性动词能与表示一段时间的状语连用,瞬间动词却不能。但是,可用别的表达方式:①瞬间动词用于“一段时间 + ago”的一般过去时的句型中;②瞬间动词可改成与之相对应的延续性动词及短语,与一段时间连用;③瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中,表示“自从……以来有……时间”的意思,主句一般用it is来代替It has been;④瞬间动词用于“Some time has passed since + 一般过去时”的句型中。请看:
A. He joined the League two years ago.
B. He has been in the League for two years.
C. It is two years since he joined the League.
D. Two years has passed since he joined the League.
二、一般现在时与现在进行时的转换
在一般现在时中,at加上名词表示“处于某种状态”,如at work(在工作), at school(上学、上课)等。此短语可与进行时态转换。请看:
Peter is at work, but Mike is at play.
Peter is working, but Mike is playing.
三、现在进行时与一般将来时的转换
在现在进行时态中go, come, leave, start, arrive等动词常与表示将来的时间状语连用表示将要发生的动作。如:I am coming, Mum! 意为“我就来,妈妈!”请看:
The train is leaving soon.
The train will leave soon.
四、“be going to+动词原形”与“will(shall)+动词原形”结构的转换
“be going to+动词原形”、表示打算、计划要做的事;将来时“will(shall)+动词原形”结构在书面语中,当主语为第一人称时,常用助动词shall。在口语中,所有人称都可以用will。请看:
We are going to visit the Great Wall next Sunday.
We shall visit the Great Wall next Sunday.
Ⅲ. 中考动词时态考点分析
一、 根据时间状语确定时态的原则
1. Hurry up! The play for ten minutes. (2002辽宁)
A. has begun B. had begun C. has been on D. began
[析] 1. C。since后接时间的起点,for后接时间段,主句动词用现在完成时,应注意瞬间动词与延续性动词的使用。
二、 在复合句根据时态呼应确定时态的原则
2. Do you know if back next week? If he back, please let me know. (2002黑龙江 )
A. he comes; will come B. will he come; comes
C. he will come; comes D. will he come; will come
[析] 2. C。if既可引导宾语从句,也可引导状语从句。充当宾语从句的连接词时,相当于whether,词义是“是否”。充当状语从句的连接词时,词义是“如果”。从时态看,if引导宾语从句时谓语动词的时态应根据主句的时态作相应的变化;引导表示将来动作或状态的条件句时,若主句用一般将来时,则从句通常用一般现在时表示将来。
三、 根据上下文已有时态信息点确定时态的原则
3. –When this kind of computer ?
--Last year. (2002天津)
A. did; use B. was; used C. is; used D. are; used
[析] 3. B。此例由下句的时间状语推断出一般过去时态,并且要考虑到被动语态。
四、 利用上下文语意确定时态的原则
4. –Hi! Lin Tao. I didn’t see you at the party.
--Oh, I ready for the maths exam. (2002江西)
A. am getting B. was getting C. got D. have got
[析] 4. B。此例由didn’t, at the party推断出应用过去进行时。
五、 时态中的“特殊”对策的原则
5. The teacher told us yesterday that December 25 Christmas Day. (2002辽宁)
A. is B. was C. has been D. will be
[析] 5. A。 有些动词其动词的时态是“违背常理”的。如宾语从句表示的是一个客观事实或客观真理时,其时态不受主句限制而用一般现在时表示。
1. 行为主体不明确,不必说出或者无法说出动作的执行者时。
Football is played all over the world.
2. 不易找到或根本就找不到动作的执行者时。
My bike was stolen.
3. 汉语含有“据说”、“有人说”等时。
It is said that another bridge has been built over the Changjiang River.
4. 汉语中含有“被”、“由”等词时。
Wei Hua is asked to come by Lin Tao.
5. 汉语中没有“被”、“由”等词,而在原句中试加这类词且句意通顺时。
These songs are usually sung by boys.
6. 某些句子习惯上用被动语态。
He was born in October, 1988.
7. 表示礼貌时。

⑸ 人教版初三英语上册语法重点,主要是时态。。
Unit1
By是个很常用的介词(有时也用作副词),在初中英语中的用法有以下几种: 1.意为“在……旁”、“靠近”。如: Some are singing and dancing under a big tree . Some are drawing by the lake. 有的在大树下唱歌跳舞,有的在湖边画画儿。 2.意为“不迟于”、“到……时为止”。如: Your son will be all right by supper time. 你的儿子在晚饭前会好的。 How many English songs had you learned by the end of last term? 到上个学期末你们已经学了多少首英语歌曲? 3.表示方法、手段,可译作“靠”、“用”、“凭借”、“通过”、“乘坐”等。如: The monkey was hanging from the tree by his tail and laughing.
猴子用尾巴吊在树上哈哈大笑。 The boy’s father was so thankful that he taught Edison how to send messages by railway telegraph.
孩子的父亲是那么的感激,于是他教爱迪生怎样通过铁路电报来传达信息。 4.表示“逐个”、“逐批”的意思。如: One by one they went past the table in the dark.
他们一个一个得在黑暗中经过这张桌子。5.表示“根据”、“按照”的意思。如:What time is it by your watch? 你的表几点了? 6.和take , hold等动词连用,说明接触身体的某一部分。如: I took him by the hand. 我拉住了它的手。 7.用于被动句中,表示行为主体,常译作“被”、“由”等。如: English is spoken by many people. 英语被许多人所说。(即“许多人讲英语。”) 8.组成其它短语。 1) by the way : 意为“顺便说”、“顺便问一下”,常做插入语。如: By the way , where’s Li Ping , do you know?
顺便问一下,李平在哪儿。你知道吗? 2) by oneself : 意为“单独”、“自行”。如: I can’t leave her by herself. 我不能把她单独留下。 3) by and by : 意为“不久以后”、“不一会儿”。如: But by and by , more and more people began to study English. 但是不久以后,越来越多的人开始学英语了。
二、动名词的构成动词后加动名词doing,相当于名词,在句子中可以做主语、宾语、表语定语等。1)★作主语(这种用法常考)
Fighting broke out between the South and the North.南方与北方开战了。2)作宾语Would you mind turning down your radio a little, please?
请问你介意调小一点收音机的音量吗?3)作表语Babysister’s job is washing,cooking and taking care of the children。保姆的工作是洗衣服,作饭和照看孩子。
Unit2
used to 的用法:(1)肯定句:used这个词没有人称的变化,to后面接动词原形。
否定句是didn’t use to….
When I was a child, I didn’t use to like apples.当我还是孩子的时候我不喜欢苹果.
疑问形式是Did you use to…?Where did you use to live before you came here?当你来这儿之前你住哪儿?
(2)含有used to 的句子的反意疑问句不要usedn’t + 主语,而用didn’t + 主语。He used to smoke, didn’t he? 他过去常常吸烟,是吗?Yes, he did./ No, he didn’t. 是的,他吸。/ 不,他不吸。
(3)used to 表示过去的习惯动作, 而不是现在的。I am used to the weather here. 我已经习惯于这里的天气了。He is used to hard work. 他习惯于艰苦的工作。
(4)used to 可以和be, have 以及其他状态动词连用,描写过去的状态。 I used to be a waiter, but now I’m a taxi-driver.我过去是一个服务员,但现在我是出租车司机。
★ 本单元的许多运用used to 的句子属于描述过去的状态。Mario used to be short.马力奥过去总是很矮。Amy used to be outgoing.爱米过去性格外向。Tina used to have long and straight hair.蒂娜过去有一头直的长头发。He used to wear black shoes. 他过去常穿黑鞋。
Unit3
本单元重点讲到了被动语态的用法英语动词的被动语态由助动词be加及物动词的过去分词构成。助动词be有时态,人称和数的变化,其变化规则与连系动词be完全一样。
一、被动语态的句式变化: 以一般现在时和动词invite为例,列表说明被动语态的句式变化:
二、各种时态的被动语态结构总结如下: 被动语态的时态是由be的时态决定的,be是什么时态,全句就是什么时态,be动词后面的过去分词不变。一般现在时的被动语态为:主+am / is / are (not)+过去分词一般过去时的被动语态为:主+was / were +过去分词
例如:我们学过的was / were born 生于,就是一个被动语态.born是个过去分词(bear)-When were you born ? -I was born in 1989. 现在进行时被动语态的构成为: 主语+is / am / are + being +过去分词
现在完成时被动语态的构成为: 主语+have / has +been +过去分词
情态动词的被动语态: 情态动词+be+过去分词
一般将来时的被动语态: 主语+will +be +过去分词
过去将来时的被动语态: 主语+would / should + be +过去分词
过去进行时的被动语态: 主语+was / were + being +过去分词
过去完成时的被动语态: 主语+had + been +过去分词
三、被动语态的用法:(1)不知道或没有必要说明动作的执行者是谁,不用by+动作执行者短语 Football is played widely all over the world. 全世界都广泛地踢足球。
(2)强调动作的承受者,这时应用by短语。The bank was robbed yesterday afternoon. 昨天下午这家银行遭到抢劫。
(3)作客观说明时,常采用一种被动语态句型It is reported that about twenty children have died of flu in the USA.
据报道美国大约二十名儿童死于流感。
四、主动语态的句子变为被动语态的方法是:(1)把原句中的宾语变为主语(2)动词改为被动形式,即be+过去分词(3)原来的主语,如果需要的话,放在by后面,如果没必要,可省略。请看下表:
主动语态 被动语态
They make trains in Zhuzhou. They use this key for locking the classroom door.Many people speak English.He wrote a letter.They are building a road. Trains are made in Zhuzhou.This key is used for locking the classroom door(by them).English is spoken by many people.A letter was written by him.A road is being built (by them).
Unit4
虚拟语气:如果我们所说的不是事实,也不是要求、命令、劝告等,而只是一种假设、愿望、建议或是一种实现不了的空想就用虚拟语气
注意:条件句分两种,真实条件句和虚拟条件句。只有在虚拟(非真实)条件句中,才用虚拟语气,而在真实条件句中,要用陈述语气。
请比较:
(1)If it is sunny tomorrow , we’ll go to the zoo.
如果明天天气好,我们将会去公园。在这句话中,明天天气好是完全有可能实现的,并非虚拟、幻想,因此是真实条件句。在本句中,适用“主将从现。”
(2)If I were you , I would go at once.
(如果我是你的话,我立刻就走。)在这句话中,条件句,“如果我是你”,但事实上,我不可能成为你,这只是假设的情况,没有实现的可能。当条件实现的可能性很小,甚至可以说没有时,就需要用虚拟语气来表示,动词发生了变化。
也就是说虚拟语气表示和现实的事实相反时,从句用一般过时。
主句用 “should/would/could/ might +动词原形。
1.If I had time, I would go for a walk.
2.If I were invited, I would go to the dinner party.
3.If I won a million dollars in the lottery, I would put it in the bank.
知识点2. He doesn’t know if he should bring a present.
此处if表示“是否”,引导宾语从句。Should此处表示“应该”。不是虚拟语气。
E.g.1. I don’t know if I should go to the party.
2.If I have enough money, I will go to Hainan .
知识点3.If I were you , I’d wear a shirt and tie.
if 引导的条件状语从句表示与现在事实相反的虚拟语气时,be动词只能用were,而不能用was。
E.g. If he were here, he would not agree with you .
知识点4. I don’t have a present. What if everyone else brings a present?
What if… “如果……怎么办?”相当于 what would happen if…
E.g. What shall I do if it snows?
知识点5.Well, dogs can be a lot of trouble.
Trouble 麻烦事 ,名词
常用搭配 :get (sb)into trouble get out of trouble what’s the trouble
“if”引导的条件句。

在选择引导定语从句的关系代词时,有如下要点:
1 由于关系代词在主句与从句间既起到联系作用,又在从句中充当一个成分,因此, 要正确判断关系代词在从句中的功能,如作主语还是宾语等。
2 当先行词指人时,关系代词可用who(做主语,宾语),that(做主语,宾语),whom(作宾语),whose(作定语)
3 当先行词指物时,关系代词可用that(做主语,宾语),which(做主语,宾语)
4 再定语从句中,作宾语的关系代词长可省略,但在介词后面的关系代词不能省略。指人时,介词后只用whom,指物时,介词后只用which。
5 在非限制性定语从句中,指人时,只用who,指物时,只用which。
1.定语从句中that与who、which的区别
2.定语从句中关系词的省略
典型例题
1. The first job ________I found was to be a cleaner.
A. where B. why C. which D. that
解析:指事物的先行词前有序数词修饰时,只能用关系代词that。故本题的正确答案是D。
2. I don’t think history is as interesting as English.(改为同义词)
I think history is ___________ interesting _________ English.
解析:答案是:less; than。意思是“我认为历史不如英语有趣”。
3. The woman who is wearing the hat is my mother.(改为同义句)
The woman ________ the hat is my mother.
解析:读题后可知:上句含义是“戴帽子的那个妇女旭我的妈妈”,对应下句,可知空格处应填“戴”,故正确答案是in。
选择填空
1. The poor boy ________ lost both his parents last year is called Mike.
A.which B.what C.who D./
2. The bridge ________ has been there for nearly fifty years still looks nice.
A.which B.what C./ D.who
3. I’m one of the students _______well in English in my class.
A.who does B.who do C.which does D.who did
4. Is this factory ________ some foreign friends visited last Friday?

Unit8
1、短语动词小结
常见短语动词结构有下面几种:
1.动词+副词 如:give up 放弃 turn off 关掉 stay up 熬夜
这种结构有时相当于及物动词,如果其宾语是代词,就必须放在动词和副词之间,如果是名词,则既可插在动词和副词之间,也可放 在短语动词后。
2. 动词+介词 如:listen of 听 look at 看 belong to 属于
这种结构相当于及物动词,后面跟宾语。
3. 动词+副词+介词 如:come up with 提出,想出 run out of 用完,耗尽
4. 动词+名词(介词) 如:take part in参加 catch hold of 抓住
2、倒装句
not only … but (also) … 不但… 而且… 用来连接两个并列的成分
(1)引导以 not only …but (also)… 开头的句子往往引起部分倒装。
因此 ⑴Not only do I feel good but (also)…. 是倒装句。也是说得要
把前面的句子中的助动词或者是情态动词放在主语的前面。如:
①Not only can I do it but (also) I can do best. 我不仅能做到而且做得最好。
⑵Not only…but (also)… 接两主语时,谓语动词随后面的主语人称和数的变化 也就是就近原则 如:
①Not only Lily but (also) you like cat. 不仅莉莉而且你也喜欢猫。
②Not only you but (also) Lily likes cat. 不仅你而且莉莉喜欢猫。
常见的就近原则的结构有:
Neither… nor…即不…也不… (两者都不)
Neither you nor I like him. 我和你都不喜欢他。
Either… or… 不是…就是… (两者中的一个)
Either Lily or you are a student.
Not only …but (also)…
