㈠ 求英语语法时态的几个典型句子

英语18种时态及例句
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。
ex: It is reported that by the end of this century the people of Chinese will have increased by 2 billion.

㈡ 英语句子的种类和例句

㈣ 求~英语五种基本句型例句

1.“主----系-----表”(SLP)句型: 在这种句型中,谓语动词是以be为主的连系动词(Linking Verb),后面跟主语补语(Subject Complement),如: These oranges have kept fresh. 这些桔子一直很新鲜。 Mary is a student / here /in the room. 玛丽是个学生/在这儿/在房间里。 有的语法家把be后面的副词(短语)或介词短语视为状语,从而形成了“主----动-----状”(SVA)这一在五种基本句型之外的句型(见上面最后一个例句)。 2.“主----谓”(SV)句型: 在这种句型中,谓语动词为不及物动词(Intransitive Verb),谓语部分通常只包括限定动词,即使有状语,也属任意性状语,即:去掉后并不影响句子结构和意义的完整,如: This bread won’t keep (for a long time). 这种面包不好(长期)存放。 Tom has left. 前面说过,有些句子中的状语是不可缺少的,这种状语被称为必具性状语,从而构成“主----动----状”(SVA)句型,但这仅限于少数几个动词的某些用法,因而不是一种主要句型,如: They are staying in a hotel. 他们暂住在一家旅馆里。 3.“主----谓-----宾”(SVO)句型: 在这种句型中,谓语动词为只带一个宾语的及物动词,这种动词被称为单宾语及物动词(Monotransitive Verb),如: He kept the money. 他保存着这些钱。 They have left the hotel. 他们已经离开了那家旅馆。 在这种句型中,状语通常也不是必不可少的,但有少数几个及物动词的某些用法要求必具性状语,从而形成了“主----动-----宾-----状”(SVOA)这一在五种基本句型之外的另一种句型,如: The train leaves London at nine. 这列火车九点钟驶离伦敦。 4.“主----谓----间宾-----直宾”(SVOiId)句型: 在这一句型中,谓语动词为能带一个间接宾语和一个直接宾语的及物动词,这类动词被称为双宾语及物动词(Ditransitive Verb),如: He kept me a dictionary. 他为我保存了一本词典。 Shall I leave you the camera? 要我把照相机留给你吗? 5.“主----谓----宾----宾补”(SVOC)句型: 在这种句型中,谓语动词为能带复合宾语(宾语+宾语补语)的及物动词,这类动词叫做复合宾语及物动词(Complex Transitive Verb),如: She kept a notebook handy. 她手头上随时有个笔记本。 His illness left him weak. 他的疾病使他身体虚弱。

㈨ 英语语法及例句

语言要遵循一定的规则,这种规则即被我们称之为“语法”。许多学生在英语学习中一听“语法”头就大,产生恐惧、厌学的心理。教师要遵循“精讲多练,讲练结合,以练为主”的教学方法,同时还要注意提高学习效率,减轻学生的作业负担,实现语言为交流工具的目的。笔者在多年的教学实践中总结:语法教学要重视例句的选择。

一、代表性

例句的选择在结构上要有代表性,起到掌握这个句型就能够举一反三的作用。历年的高考试题、学生比较熟悉的经典习题等,我们不妨拿来一试。

如,讲动词不定式的主动式和被动式:

She went to the ball not only to see,but also to be seen.(她去参加舞会不仅为了见见世面。也为了出出风头。)

如with复合结构,即with+宾语+宾语补足语:

With two exams to worry about,I have to work really hard this weekend.(2004,北京)

关于情态动词must have done 表对过去情况肯定的猜测:

I have lost one of my gloves. I must have dropped it somewhere. (2005,北京)

二、简洁性

有些教师认为,例句越难越好,难的会了容易的就更会了;还有教师因为学生上课不好好听课,主张选难懂的句子来镇镇他们。其实不然。正如人的认知规律“由易到难”,对于语法学习有困难的学生而言,复杂的例句只会让他们更头痛,对语法更畏惧,对英语学习更没兴趣。选择结构简洁的例句,语言上通俗易懂,读来朗朗上口,学生容易记,也记得牢。

如讲动词不定式的语法功能时:
1.
He is always the first to come and the last to leave.(to do 不定式作定语,修饰序数词)
2.
To see is to believe.(to do 不定式坐主语和表语)
对比学习Seeing is believing.(动名词作主语和表语)

3.
It is easier to say something than to do something. (to do 不定式作句子的真正主语,It为形式主语)

对比学习It is easier said than done.
三、趣味性

兴趣是产生学习激情的巨大动力。选择内容生动有趣的例句,如谚语、成语、俚语等,这样学生有了兴趣,就愿意多念,念熟了就能由次及彼。

如: 倒装结构“so+助动词+主语+谓语+------”:
As a man lives,so shall he dies.(有生就有死)

As a man sows, so shall he reap.(种瓜得瓜。种豆得豆)

下边还有一个比较级的句子:

The old man was not any more fond of being read to than the old woman.

此句的翻译为“那个老头和老太太一样,都喜欢别人读书给他们听”。有学生将它译为“那个老头不喜欢别人给他念书,就喜欢哪个老太太”,这就要闹笑话了。

四、积极性
选择一些内容积极向上的语法例句,如名言警句等。这不仅能让学生掌握相应的语法知识,同时也起到教育的情感目的,起到教育人的作用。

One half of knowing what you want is knowing what you must give up before you get it.

知道想要什么,一半在于知道得到它之前必须放弃什么。 (表语从句)

Victory will not come to me unless I go to it. 胜利是不会向我走来的,我必须自己走向胜利。 (条件状语从句)

All that litters is not gold. 闪光的并非都是金子。 (定语从句)
五、综合性

在实际的语法教学中,很少有独立的语法项目,很多时候许多的语法知识汇集在一个句中。选择综合性较强的例句来讲解,让学生背诵,能起到事半功倍的效果。如:

It was playing computer games that cost the boy much time he ought to have spent in doing his lessons.

这个例句综合了:
强调句型:It was---that---

定语从句:---time (that) he ought to have---lessons

情态动词:ought to have spent---

动名词作主语:---playing computer games cost the boy much more time---

总之,适当的例句选择不仅能够让学生理解语法,掌握重点,还能在茫茫题海中减轻学生大量背诵和大量习题的课业负担,有效提高教学质量。教师要注意多研究,多积累,找出更多的语法教学方法。
