= …the + 最高级+(名词)+ in / of … “比任何其他都…”

(二)副词

一、定义:副词用来修饰动词、形容词,其他副词、介词短语或全句。

二、副词的位置:

1.大多数副词都可以放在动词后面,如果是及物动词,一般放在宾语后面。如:(1) He is reading loudly. (2) He is reading a book loudly.

频率副词(如:always, often, usually, sometimes, seldom, hardly, ever, never等)一般位于所修饰的动词之前,be动词,情态动词,助动词之后,若有一个以上的助动词,通常位于第一个助动词之后。如:(1) He usually comes early. (2) The English song has never been heard.

2.already, yet, once, nearly, almost, just, really, certainly, suddenly, soon, still等副词所在的位置与频率副词相同。

3.程度副词(very, so, quite等)一般位于所修饰词之前,但enough则位于形容词、副词之后。如:(1) I'm very happy to see you.

(2) He is tall enough to reach it.

4.修饰全句的副词一般位于句首,若不表示强调也可以位于句中或句末,这时要加逗号。如果放句首,逗号也可以省略。如:Luckily, he wasn't hurt badly.

三、副词比较等级的基本句型与形容词相同。

(三)可修饰比较级的词有:much, far, even, a little, a bit等。

(四)形容词最高级前必须加“the ”,副词的最高级前“the”可以省略。

(五)不规则的形容词和副词的比较级和最高级。

(六)形容词和副词比较等级口决:

as…as间原级;than前常用比较;

说明"越来越如何",and 连两比较级;

三者以上最高级;of / in前用最高级;

one of 后用最高级;最高级前要加“the”

六、介词

一、介词一般位于名词或代词之前,在句中不单独做任何成分。介词本身有独立的含义,但

意义不够完整,在句中使用时,后面必须接有宾语构成介词短语后,才能表达完整的意义。介词短语在句中常作状语、定语、表语或宾语补足语。

二、介词的用法:

(一)表示时间的介词的用法:

1。at, on, in

注意:“on / in +冠词/ 形容词性物主代词+ 交通工具名词”这种交通方式的表达可以转换成“ by +交通工具名称”。例:on a bike = by bike

如果交通工具名词为car,习惯上用in ,其他多用on。如:He learns English on TV.

(4)with主要指某一具体的劳动工具、材料或用身体部位。如:

①They like writing with a brush.他们愿意用毛笔写字.

② We see with our eyes and hear with our ears.我们用眼睛看,用耳朵听.

八、主谓一致

一、主语和谓语意义上致:指根据句子意思主语的人称和数应是单数还是复数,从而谓语动

词应与其保持一致。

1.若一个句子的主语是单数,则谓语动词应用单数形式(am, is, was, has)及可以带-s及-es

的动词形式。如:She comes here once a week.

2.表示时间、重量、金钱、距离的复数名词作主语,通常被看作一个整体,谓语动词用单数。如:Three years has already passed quickly.三年时间很快已经过去了。

3.以-s结尾的名词,news(新闻消息);works(著作);maths(数学);

plastics(塑料物)以及以-ics结尾的学科名称名词。如physics(物理学);politics(政治)

等作主语,谓语动词须用单数。如:I don't think the news in the newspaper is true.

4.family, class, police等词在句中作主语时,当它们表示整体概念时,谓语动词用第三人称单

数形式;而当它们表示其中的各个成员时,谓语动词用复数形式。如:

①His family is moving next month.他家下个月要搬家了.

② His family enjoy watching football match. 他全家人都爱看足球比赛.

5.people一词表示"人"之意时,总是表示复数意义,面没有单数形式,所以谓语动词用复数形式.如:Look! Three people are standing under that tree.

6.由and连接的两个主语的单数名词指同一个人,同一物时,谓语动词要用单数形式;当and

连接的两个作主语的单数名词分别指两个人或物时,谓语动词要用复数形式。如:(1)Bread and butter is a common food over the country. 面包涂黄油是这个国家很普遍的食物。

(2) Lucy and LiLei are good friends. 露西和李雷是好朋友。

注意:在这种情况下,and 后的名词没有冠词,表示“同一个人或物”,作主语,谓语动词用

单数。若and 前后的名词都有冠词,则表示两个人或物,作主语时,谓语动词用复数。

区别:(1)The writer and artist has given us a talk. 这个作家兼艺术家已经给我们作了报告。

(2)The writer and the artist have given us a talk. 这个作家和这个艺术家都已经给我们作了报告。

7.主语为trousers 裤子; shoes鞋; glasses眼镜等成对出现的名词, 谓语动词用复数。

如:His glasses are news.

但:这些词前用a pair of 或pairs of …修饰时,谓语根据pair单复数来确定。

如:A pair of shoes costs 150 yuan.

8.“the + 姓氏名词复数”表示“…一家”或“……夫妇”,当其在句中作主语时,谓语动词应用复

数形式。如:The Whites enjoy working in China.

9.“the +形容词”表示这一类,作主语时,谓语动词用复数。如:老年人the old ;年青人the young ;富人the rich ;穷人the poor等。如:The poor were working day and night in old days.

10.“The number of +复数名词”意为“……的数量”;“many a + 单数名词”表示“许多……”;“more than one + 单数名词”表示“不至一个……”作主语时,谓语动词用单数。如:

(1) The number of students is forty in this class.这个班学生的数量是40人。

(2) More than one students likes playing. 不至一个学生喜欢玩。

11.“A number of +复数名词”作主语,表示“许多……”,谓语动词用复数。

如:A number of students are in the classroom.

12.一些词如lots of , plenty of , a lot of 加不可数名词时,作主语,谓语动词用单数形式。但

后跟复数名词时,谓语动词要用复数形式。如:

(1) A lot of money is spent on clothes. 很多钱都花在买衣服上了。

(2) A lot of students are going to my house. 许多学生要来我家。

13. a great deal of / a large amount of 意为“许多,大量……”,只能接不可数名词,其谓语动

词要用单数形式。

14.everyone, everybody, nobody, somebody, anything, nothing, something, everything等不定代

词在句中作主语时,谓语动词用单数。如:

Everything begins to grow fast in spring.春天万物开始迅速生长。

15. every, each, one, another, little, a little, much 加单数名词,作主语,谓语动词要用单数形式;both, few, a few, many加复数名词,作主语,谓语动词要用复数形式。

如:(1) Each day passes without any change. (2) Both girls are beautiful girls.

16.“either +单数名词”或“either of +复数名词”表示“两者中的一个……”;“neither +复数名词”或“neither of +复数名词”表示“两者都不……”在句中作主语,谓语动词用第三人称单数形式。如:(1) Neither answers is right.两个答案都不对。

(2) Neither of the twins likes bread.那对双胞胎都不喜欢面包。

17. 动词v-ing形式,动词不定式(即:to+动词原形)或从句在句中作主语时,谓语动词应用单数形式。如:(1)To do is much more difficult than to say.

(2) Doing dyes exercises is good for our eyes.

(3) When we will start hasn't been decided yet.

二、主语和谓语在语法上的一致:即指谓语动词与主语的单复数形式上保持一致。

1.若句中主语加上插入部分,则谓语动词应与主语一致。

主语+ with / as will as / without / including / besides / except/ but / together with等组成的短语,谓语动词要与这些短语或词前的主语确定。

如:(1)T he woman with the two boys is American.

(2)All the teachers, including Miss Li, are going to a meeting.

2.“each +单数名词”或“each of +代词/ 名词”作主语,谓语动词用单数。

如:Each of the children has an orange.

三、主语和谓语就近一致:即指谓语的人称和数与靠近它的那个主语保持一致。

1.there be 结构:当there be +单数名词时,谓语动词be为单数形式;当there be +复数名词时,谓语动词be 为复数形式。如:There is a pen in your pencil-box.

2.当主语中出现了or, either … or, neither… nor, not only…but also时,谓语动词要根据就近原则与离谓语最近的主语保持一致。

如:Neither he nor I am a student now.

九、感叹句:

1、定义:由what 和how引导,表示说话时的惊异、喜悦、气愤等情绪,句尾有惊叹号“!”,读时用降调,在口语中常用省略句,有时只有一个词或词组。

如:Great! How cold!

2、结构:①What + a / an +形容词+名词单数+主语+谓语!

②What + 形容词+名词复数+主语+谓语!

③How + 副词+主语+谓语!

④ How +形容词+ the + 名词+谓语!(the + 名词为句子主语)

e.g:(1)、He is a kind boy. (变为感叹句) → What a kind boy he is!

(2)These are very beatiful flowers. (变为感叹句) →What beatiful flowers these are!

(3). They are playing happily. (变为感叹句)→How happily they are playing!

由肯定句变为感叹句时,肯定句出现的副词so, very , quite, rather, pretty,too等要去掉。

e.g,What an interesting book it is. ( 同义句)→How interesting the book is!

十、祈使句:

英语中的祈使句通常用来表示请求、建议、命令、等语气,习惯上以动词原形开头,句未,一般用句号或感叹号。

1、祈使句的肯定式:

(1)动词原形+其它成分。如:come here 过来。

(2)please +动词原形+其它成分,(=动词原形+其它成分+ please 注意:please 位于句未时,其前多用逗号隔开,后面的句式语气上比前面的句式更为客气和礼貌。

如:Please come in =come in ,please .

(3)Be +形容词+其它成分。如:Be quiet , please !

(4)Let +宾语+动词原形其它成分。如:Let's go .Let's me go in

(5)No+v-ing. No smoking!

2、祈使句的否定式:在动词原形前加Don’t .

如:Watch TV ,please 否定句Don't watch TV

十一、宾语从句

一、定义:用来作宾语的句子叫宾语从句,使用宾语从句需注意引导词、语序(用陈述句语序)、时态正确。

二、变宾语从句的方法(类似于直接引语变间接引语):

(一)确定主从句:根据句意来判断,可以跟宾语从句的动词有think, say, tell, ask, decide, hope, wish, know等。

(二)确定引导词

1、从句为陈述句时用that 引导,that无意义,可省略。

2、从句为一般疑问句由if / whether引导。如:

Are they students? He asks. → He asks if they are students.

3、从句为特殊疑问句,由原来的特殊疑问词引导。如:

①How many students are there ? He asked me. → He asked me how many students there were.

②What's the matter with her? Can you tell me ?→ Can you tell me what's the matter with her? 主句的谓语为think , believe, guess, suppose且主句的主语为I , we时,宾语从句的否定前移。如:I think. He doesn't like the present.(合并为宾语从句)

→ I don't think he likes the pr esent.

4、下列情况必须用whether 不用if :

(1)从句作介词的宾语时。如:We are talking about whether we'll go back to our hometown. (2)后跟不定式,或与or not连用时必须用whether。

如:①He asked me whether to sit at the front.(简单句)

② I don't know whether he's free or not. (复合句)

6.当从句为祈使句时,肯定的变为tell / ask sb. to do sth.;否定的变为tell / ask sb.not to do sth

如:He told me. Don't play in the street.(合并为一句)

He told me not to play in the street.

(三)确定时态和人称

1.当主句为Could you tell me/us时,从句时态不受主句限制。

2.从句的时态:当主句为一般现在时时,从句时态不变;当主句为一般过去时时,从句用相应的过去时态:即:一般现在时→一般过去时;一般过去时→过去完成时(句中无过去时间状语);一般将来时→过去将来时;现在进行时→过去进行时;现在完成时→过去完成时(四)确定语序及标点符号(根据主句判断)

(五)注意:当从句表示自然规律或客观事实时,即使主句为过去时态,从句也必须用一般现在时。这类句子有:

1.Light travels faster than sound. 光比声音传播的速度快。

2.The sun rises in the east. 太阳从东方升起。

3.The earth goes / moves around the sun. 地球绕着太阳转。

4.The moon goes / moves around the earth. 月亮绕着地球转。

5.The earth is round. 地球是圆的。

如:My father told me that the sun rises in the east.

十二、状语从句

状语从句指句子用作状语时,起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导,也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开,位于句尾时可以不用逗号隔开。

1.引导时间状语从句的连词

主要有when, while, as, by the time, before, after, since, till/until, as soon as等。其中when?while和as都可表示"当……时候",但用法有区别:

when(当......的时候), after(在...之后), before(在...之前), as soon as(一....就...) , until(直到),引导的时间状语从句, 主句用一般将来时(will+v.), 则从句用一般现在时

when和while引导的时间状语从句,如果主句用一般过去时(动词的过去式),则从句用过去进行时(was/ were +v.-ing)., 表示当一个动作正在进行时, 另一个动作发生了.

while引导的时间状语从句, 主句和从句都用过去进行时(was/ were +v.-ing)., 表示当一个动作正在发生的时候, 另一个动作也在同时发生.

when引导的时间状语从句. 如果主句用过去进行时(was/ were +v.-ing)., 则从句用一般过去时(动词的过去式). 表示当一个动作发生的时候, 另一个动作正在进行.

by the time= when(当...的时候),引导时间状语从句, 如果主句用过去完成时(had +过去分词),则从句用一般过去时(动词的过去式).表示当一个动作发生了的时候, 另一个动作已经在这个动作之前发生了(即“过去的过去”).

as意为"边……边……"或"与……同时",重在表示两个动作同时发生。伴随进行。as从句是终止性动词时,主句通常也必须是终止性动词。例如:

They sang as they danced.

2.引导原因状语从句的连词

原因状语从句一般由because, since, as, for引导?注意as,because,since和for的区别:

①如果原因是构成句子的最主要部分,一般用because。because引导的从句一般不放在句子的开头。例如:

I missed the train because I got up late.

注:对于以why开头的问句,一般只能用because引导的从句来回答。

②如果原因已为人们所知,或不如句子的其余部分重要,就用as或since、since比as稍微正式一些。as和since引导的从句一般放在句子的开头。例如:

As he was not well,I decided to go there without him.

Since this method doesn't work, let's try another.

③for表示所说的理由是一种补充说明,因此,for引导的从句可以放在括号里,而且for引导的从句一般不放在句子的开头。例如:

I decided to stop and have lunch, for I was feeling quite hungry.

3.引导结果状语从句的连词

主要有so/such…that…,so that等。

1) so...that结构在某种情况下可以与enough to和too...to结构相互转换。例如:

She is so short that she can't reach the buttons of the lift. =She is too short to reach the buttons of the lift.

2)so that也可以引导结果状语从句,意为"结果是;以致于"。例如:

They missed the bus so that they were late for class.

注:so that也可引导目的状语从句,此时可用to或in order to替换,将其改为简单句。例如:

He got up early so that he could get to school on time. =He got up early to get to school on time. =In order to get to school on time,he got up early.

4.条件状语从句

if 的用法:

意为“如果”,引导真条件状语从句,主句用一般将来时(will+v.)、祈使句或情态动词+ 动词原形,从句用一般现在时(I /we/you/they/复数名词+v. 或He/She/It/单数名词+动词的第三人称单数)

意为“如果”,引导虚拟条件状语从句,主句用would+v., 从句用动词的过去式(be动词用were).

意为“是否”引导宾语从句,如果主句为一般现在时(I /we/you/they/复数名词+v. 或He/She/It/单数名词+动词的第三人称单数),从句可根据句子选用任何时态。如果主句为一般过去时(动词的过去式),则从句要变为相应的过去时态。

2、when / while / as引导时间状语从句,表示主句和从句的动作同时发生;before表示主句的动作发生在从句的动作之前;after则表示主句的动作发生在从句的动作之后;as引导时间状语从句时,强调同时发生,不分先后。如:

When I walk to school, I walk _____________________ (沿着人行道).

☆when / while / as的区别

①若主、从句表示两个同时进行的持续性动作,且强调主句表示的动作延续到从句所指的整个时间,通常要用while。但是,若主、从句表示的两个同时进行的动作含有“一边……一边”之意思,通常要用as。如:

Don’t talk while you’re eating.吃饭时不要说话。

I kept silent while he ________________.在他写的时候,我默不作声。

She sang as she went along.她边走边唱。

②若从句是短暂性动作,而主句是持续性动作,可以用as或when但不用while。如:

It was raining ___________ when / as we arrived.我们到达时正下着大雨。

③若主、从句表示的是两个同时(或几乎同时)发生的短暂性动作,一般要用as (也可用when)。如:

I will __________________ (等你) until / till you come to see me.

I will read the book until / till I ____________ (finish) it.

②主句的谓语动词是非延续性动词时,用否定形式表示主句的动作直到until所表示的时间才发生,构成句式not …until;有时不用not,而用其他,如never,nothing等表示否定的词。如:

I didn’t go to bed until I finished my homework.我直到完成作业才去睡觉。

4、since引导的时间状语从句,表示“自从……以来”,主句用一般现在时或现在完成时,从句用一般过去时。常用结构为:“It has been…+since从句”或“It is …+since从句”。如:

①It has been / is about ten years since I graduated from Nanjing University.

我从南京大学毕业大约十年了。

②I have worked in this school since I graduated from Nanjing University.

高考真题语篇型语法填空专题展示-详解篇

2016-2018高考真题展示 Passage 1(2018课标全国Ⅱ) 阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。 Diets have changed in China—and so too has its top crop. Since 2011, the country 1 (grow) more corn than rice. Corn production has jumped nearly 125 percent over 2 past 25 years, while rice has increased only 7 percent. A taste for meat is 3 (actual)behind the change: An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn’s rise: The government encourages farmers to grow corn instead of rice 4 (improve)water quality. Corn uses less water 5 rice and creates less fertilizer(化肥)run-off. This switch has decreased 6 (pollute)in the country’s major lakes and reservoirs and made drinking water safer for people. According to the World Bank, China accounts for about 30 percent of total7 (globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005—when the govern- ment8 (start) a soil-testing program9 gives specific fertilizer recommendations to farmers and 2011, fertilizer use dropped by 7.7 million tons. That prevented the emission(排放)of 51.8 million tons of carbon dioxide. China’s approach to protecting its environment while 10 (feed)its citizens “offers useful lessons for agriculture and food policymakers worldwide,”says the bank’s Juergen Voegele. 答案 [语篇解读]本文是一篇说明文。自2011年以来,随着中国人的饮食结构的变化,在中国种植玉米的数量显著增加,而种植水稻的数量下降了。 1.has grown句意:自2011年以来,中国种植玉米的数量超过了水稻。本题考查时态和主谓一致。根据句中时间状语Since 2011可知,此处使用现在完成时,且主语为单数,故填has grown。 2.the句意:在过去的25年里,玉米的产量已经激增了将近125%,而水稻的产量只增长了7%。本题考查冠词。over the past 25 years在过去的25年里。 3.actually句意:对于肉类的喜爱实际上是这一变化背后的原因:中国的玉米有很重要的一个作用就是,用来饲养鸡、猪和牛。本题考查副词。此处需用副词作状语,故用actual的副词形式actually。 4.to improve句意:玉米产量增长的另一个原因是:政府鼓励农民种植玉米而不是水稻来提高 水质。本题考查非谓语动词作状语。此处“提高水质”为鼓励农民种玉米的目的,故使用动词不定式作目的状语。 5.than句意:玉米用水量比水稻少,造成更少的化肥流失。本题考查介词。根据句中的less 可 知,此处表示比较,故使用介词than。 6.pollution句意:这种变化已经减少了中国主要湖泊和水库的污染,使人们的饮用水变得更 安全了。本题考查名词。空格处作decreased的宾语,故使用pollute的名词形式pollution。 7.global句意:根据世界银行的统计,中国占了全球化肥总消耗量的大约30%。本题考查形容词。空格处作fertilizer consumption的定语,故使用globe的形容词形式global。 8.started句意:中国农业部发现在2005年和2011年之间,化肥的使用减少了770万吨。2005年 政府启动了土壤检测项目,它向农民推荐特定的化肥。本题考查时态。关系副词when=in 200 5,由此可知此处使用一般过去时。

初中语法祈使句专项讲解

初中语法祈使句专项讲解 1、祈使句的概念表示请求、命令、建议、祝愿、邀请或要求的句子叫祈使句。用于祈使句句首的动词总是用原形,不能用其他形式。如:Shut the door! 把门关上!Have a cup of coffee! 喝杯咖啡吧!Let them go by train、叫他们坐火车去吧。祈使句的主语通常为第二人称(you),但一般都被省略,只有在特殊的情况下才把主语(you)补充出来。如:You be quiet! 你安静! You go and tell him, Chris、克立斯,你去告诉他。You wait here for a moment、你在这儿等一会儿。有时祈使句的主语也可以是everybody, somebody, anybody, nobody等不定代词。如:Stand up, everybody! 全体起立!Nobody move、任何人都不许动。 2、祈使句表示强调为了加强祈使句的语气,我们通常是在祈使句的动词原形前加上助动词do,此时通常译为“一定”“务必”等。如:Do be careful、务必要小心。Do let me go、一定让我去。副词never和always有时可用于祈使句句首,表示强调。如:Never do that again、再不要这样做了。Always look in the mirror before starting to drive、一定要先看看反光镜再开车。 3、祈使句的否定式构成祈使句否定式的方法很简单,那就是在动词原形前加don’t不管祈使句所用的动词为什么性质动

词,情况都是一样。如:Open the window、把窗户打开。 →Don’t open the window、别把窗户打开。Come next Monday、下周星期一来。对于以let us或let’s开头的祈使句,其否定式通常是在不定式之前放一个not。如:Let’s tell him the truth、我们把实情告诉他吧。→Let’s not tell him the truth、我们不要把实情告诉他。但在日常口语中,我们也可以把don’t放在let’s之前。如:Let’s don’t tell him the truth、我们不要把实情告诉他) 4、祈使句与连用please为了使祈使句的语气变得委婉,我们可以在祈使句的句首或句末加上please若加在句首,其后不用逗号;若加在句末,则通常会在please前加一个逗号。如:Step this way, please、请这边走。Please type your letter、请把你的信打出来。Open the window, please、请把窗户打开。如果是否定祈使句,则通常将please加在don’t之前。如:Please don’t get angry、请不要生气。Please don’t telephone before8 a、 m、早8点以前请不要打电话。 5、祈使句的时间概念祈使句所表示的时间总是指将来,所以与它连用的句子原则上要用将来时态来与它呼应。如:Give me a hand, will you? 帮我一个忙,好吗?由于give me a hand表示隐含将来意义,所以句中的will you 不能改为do you。Try again and you will succeed、你再试就会成功。由于句中的 try again隐含将来意义,所以句中用了you will succeed,而
