英语语法的学习,是学好英语的重要内容。下面是读文网小编为大家收集整理的高二英语语法知识点,相信这些文字对你会有所帮助的。
英语中过去分词可作宾补,(此时的过去分词一般是及物动词)表被动意义或完成意义,有时两者兼而有之。做宾补的过去分词与宾语有逻辑上的动宾关系,即宾语是过去分词动作的对象。如:
She found the door broken in when she came back.(宾补与宾语有被动的关系,表一种状态。)
一. 过去分词用在表状态的动词keep,leave等的后面。
Eg:They kept the door locked for a long time.
Keep your mouth shut and your eyes open.(谚语:少说多看)
Don't leave such an important thing undone.
Don't leave the windows broken like this all the time.
二.过分词用在get,have,make, 的后面。
1.注意“have +宾语+过去分词”的两种情况:
A)表"让某人做某事/让某事(被人)做"
eg: I have had my bike repaired.
The villagers had many trees planted just then.
B)表"遭遇到某种不幸,受到打击/受....影响,蒙受..... 损失"
Eg:I had my wallet stolen on a bus last month.
The old man had his leg broken in the accident.
He had his leg broken in the match yesterday.(MET1986)
2."make+宾语+过去分词",在这种结构中,过去分词的动词必须是表示结果含义的。如:
They managed to make themselves understood in very simple English.
I raised my voice to make myself heard.
三、过去分词用在感观动词watch,notice,see,hear,listen to ,feel,find等后面。如
When we got to school,we saw the door locked.
We can hear the windows beaten by the heavy rain drops.
He felt himself cheated.
The managers discussed the plan that they would like to see carried out the next year.(NMET2000)
四、过去分词用在want,wish,like ,expect等表示“希望,愿望”这一类动词后面做宾补。如
The boss wouldn't like the problem discussed at the moment.
I would like my house painted white.
I want the suit made to his own measure.
I wish the problem settled.
五、过去分词用在“with +宾语+宾补”这一结构中,过去分词与宾语之间是动宾关系。如:
The thief was brought in with his hands tied behind his back.
With many brightly-coloured flowers planted around the building ,his house looks like a beautiful garden.
With everything well arranged,he left the office.
六、过去分词、现在分词、和不定式作宾补的区别。
现在分词作宾补:宾语和补语之间是主谓关系。其动作与谓语动作同时进行。
过去分词作宾补:宾语和补语之间是动宾关系。其动作先于谓语动作。
不定式作宾补:表一个完成的动作、或表一个很短时间内看到、听到或感觉到的具体动作。

语法知识一直都是英语学科中比较重要的一项知识,学好语法才能更好的学好英语。下面就让读文网小编给大家分享一些高二英语语法知识点总结吧,希望能对你有帮助!
1.定义:用作宾语的从句叫宾语从句。
2.构成:关联词+简单句
3.引导宾语从句的关联词有三类:
(1)从属连词that。如:He told us that he felt ill.他对我们说他感到不舒服。I know he has returned.我知道他已经回来了。注:that在引导宾语从句时也并不是任何情况下都可以省略。在以下情况下,that不能省略。
1.Everybody could see what happened and that Tom was frightened.(and连接两个宾语从句,that宾语从句放在and的后面时,that不能省略。)大家都会看出所发生的事情并知道Tom非常害怕。
2.I know nothing about him except that he is from the south.(that引导的宾语从句作介词宾语时,that不能省略。)对他我一无所知,只知道他是南方人。
3.That he ever said such a thing I simply don’t believe.(that从句位于句首时,that不可省略。)我简直不相信他曾说过这样的话。
4.We decided,in view of his special circumstances,that we would admit him for a probationary period.(主句谓语动词与that从句之间有插入语,that不可省略。)鉴于他的特殊情况,我们决定应允他一段试用期。
(1)介词宾语从句 宾语从句也可用作介词的宾语。如:He was deeply displeased by what had occurred that day.他对那天发生的事感到很不快。I walked over to where she sat.我走向她坐的地方。I am curious as to what he will say.我很想知道他要说什么。Your success will largely depend upon what you do and how you do it.你是否成功将主要取决于你做什么和怎样做。有时介词可以省略。如:I don’t care (for)who marries him.我不管谁跟他结婚。Be careful (as to)how you do that.你要注意做这件事的方式。
(2)从属连词if/whether。如:I doubt whether he will succeed.我怀疑他是否会成功。I don’t know if you can help me.我不知道你能否帮助我。
(3)连接代词who,whom,whose,what,which,whoever,whatever,whichever 连接副词 where,when,how,why。如:Who or what he was,Martin never learned.他是什么人?他是干什么的?马丁根本不知道。I wonder what he’s writing to me about.我不知道他要给我写信说什么事。I’ll tell you why I asked you to come.我会告诉你我为什么要你来。You may do what you will.你可做任何你想做的事。

初一英语上册语法与句型的知识点都有哪些呢?接下来是读文网小编为大家带来的关于初一英语上册语法与句型知识点,希望会对大家有所帮助。
be动词有三种变形,分别是:am, is, are。记忆口诀:
"我"用am, "你"用are, is用于"他、她、它";单数全都用is,复数全部都用are。
一.人称及人称代词的不同形式(主格和宾格)
1、三种人称:第一人称(I, we),第二人称(you, you),第三人称(he, she, it, Maria)。
2、人称代词的主格,即人称代词位于句子主语位置时的形态:I, We, You, You, He, She, It, Maria。
3、人称代词的宾格,即人称代词位于句子宾语位置时的形态:me, us, you, you, him, her, it。
4、形容词性物主代词:my, our, your, your, his, her, its, their。
5、名词性物主代词:mine, ours, yours, yours, his, hers, its, theirs。
6、反身代词:myself, ourselves, yourself, yourselves, himself, herself, itself, themselves。
二.基数词(表示数量多少的词,大致相当于代数里的自然数)
zero, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, twenty-one, twenty-two, twenty-three,twenty-four, twenty-five, twenty-six, twenty-seven, twenty-eight, twenty-nine, thirty, forty, fifty, sixty,seventy, eighty, ninety, one hundred,one hundred and one。
三.一般疑问句及特殊疑问句
1、一般疑问句:能用Yes或No来回答的问句。一般疑问句句尾读升调。
2、特殊疑问句:不能用Yes或No来回答的问句。特殊疑问句句尾读降调。
四.可数名词变复数
可数名词变复数时,有规则变化和不规则变化两种。
1、规则变化:
1)一般情况直接在词尾加"-s ",如:cake-cakes, bag-bags, day-days, face-faces, orange-oranges等;
2)以s, x, sh, ch结尾的词,要在词尾加"-es ",如:bus-buses, watch-watches, box-boxes等;
3)以辅音字母加y结尾的词,变y为i再加"-es ",如:baby-babies, country-countries, family-families等;
4)部分以f (e)结尾的词,变f (e)为"ves ",如:knife-knives, half-halves等;
5)以o结尾的词,加"-s "或"-es ",如:zoo-zoos, photo-photos, tomato-tomatoes, potato-potatoes等。记忆口诀:除了"英雄"hero外,凡是能吃的,加"-es ",不能吃的加"-s "。
2、不规则变化:
1)改变单数名词中的元音字母:man-men, woman-women, foot-feet, tooth-teeth等;
2)单、复同形:sheep-sheep, Chinese-Chinese, Japanese-Japanese等;
3)其他形式:mouse-mice, child-children等。
五.简单句的成分及主谓一致原则
最基本构成:主语+谓语+宾语,其中谓语由动词来充当。
主谓一致原则,就是句子的谓语要始终与主语保持数量上的一致性。当主语是第三人称单数(简称"三单"
")时,谓语动词也要相应变成单数形式;当主语非"三单"时,谓语动词就用原形。实意动词变"三单"的规则如下:
1)一般动词在词尾加"-s ",如:like-likes, tell-tells, play-plays等;
2)以字母s, x,ch, sh结尾的动词加"-es ",如:guess-guesses, teach-teaches, watch-watches等;
3)以o结尾的动词一般加"-es ",如:do-does, go-goes等;
4)以辅音字母加y结尾的动词,先变y为i,再加"-而是",如:fly-flies, carry-carries等;
5)have的三单形式是has。
六.冠词的用法(名词前面必须要有冠词)
冠词分为定冠词(the)和不定冠词(a, an)两种。
1、定冠词the表示"特指",可译为"这个"、"那个"、"这些"、"那些"。
2、不定冠词a, an用来表明(可数)名词的数量是"一个"。an用于以元音开头(注意不是以元音字母开头)的单词前,a则英语非元音开头的单词前。
3、不定冠词a, an与基数词one的区别是:不定冠词不是刻意强调"数量",而基数词则强调"数量"。
七.助动词(do, does )的用法
只有实意动词作谓语时才涉及使用助动词。以like为例:
1)当句子为肯定句时不涉及使用助动词,只涉及"主谓一致"原则。
eg : I like English a lot.
Michael likes Chinese food very much.
2)当句子为否定句时,要根据主语的人称来决定使用相应的助动词:当主语为"三单"时,要使用does;当主语为"非三单"时,用助动词原形do。例如把下列句子变否定句:
Kangkang likes math.----Kangkang doesn't like math.
They like sports.------They don't like sports.
3)当句子变疑问句时,同样要根据句子的主语来决定在句首使用Do或Does.例如下列句子变问句:
Michael likes Chinese Food.----Does Michael like Chinese food? Yes, he does./ No, he doesn't.
Jane and Helen like music.----Do Jand and Helen like music? Yes, they do./ No, they don't.
八.名词所有格
1、Kangkang's books;Tom and Helen's desk; Ann's and Maria's bikes;
2、用of表示"......的",但要从of后往of前翻译:a book of mine(我的一本书)
3、have与of的区别:
have一般表示"主动拥有",往往用于有生命的人或动物;无生命的物体一般不能"主动拥有",表示所属关系时要用of。例如:
I have a new bike. She has two big eyes.
a door of the house

3. There be/ haveThere be "有",其确切含意为"某处或某时存在某人或某物。"其结构是:There be + 某人或某物 + 表示地点或时间的状语。There be 后面的名词实际上是主语,be 动词的形式要和主语在数上保持一致,be动词后面的名词是单数或不可数名词时用is,名词是复数时用are。例如:
(1) There is a bigbottle of coke on the table. 桌上有一大瓶子可乐。
(2) There is adoll in the box. 那个盒子里有个娃娃。

初一英语语法的知识点有哪些呢?接下来是读文网小编为大家带来的初一英语语法知识点归纳,供大家参考。
一、词法
1、名词
A)、名词的数
我们知道名词可以分为可数名词和不可数名词,而不可数名词它没有复数形式,但可数名词却有单数和复数之分,复数的构成如下:
一)在后面加s。如:fathers, books, Americans, Germans,apples, bananas
二)x,sh, ch, s, tch后加es。如:boxes,glasses, dresses, watches, wishes, faxes
三)1)以辅音字母加y结尾的变y为i再加es如:baby-babies, family-families,duty-duties, comedy-comedies, documentary-documentaries, story-stories
2)以元音字母加y结尾的直接加s。如:day-days,boy-boys, toy-toys, key-keys, ways

小学的二年级英语知识点学习是很帮助小学生更好学习英语的,以下是小编为大家整理推荐关于小学二年级的英语语法知识点归纳,欢迎大家参阅!
一、定义
名词是表示人或事物名称的词。它既可以表示具体的东西,也可以是表示抽象的东西。
二、分类
1. 名词可以根据意义分为普通名词和专有名词
如:John is a student
student是普通名词,John是专有名词
普通名词前可以用不定冠词a/an, 定冠词the 或不加冠词,专有名词前一般不加冠词,专有名词的首字母要大写。
2. 普通名词又可以分为个体名词、集体名词、物质名词和抽象名词,其中个体名词与集体名词是可数名词,物质名词和抽象名称是不可数名词。
3. 专有名词
专有名词是表示人名、地名、团体、机构、组织等的专有名词,多为独一无二的事物。
三、名词的数
1、名词分为可数名词和不可数名词。
可数名词——可以数的名词
不可数名词——数不清(没有复数)
Drink?milk tea water orange juice coke coffee porridge
Food?rice bread meat fish fruit cake dumplings
2、可数名词与不定冠词a(an)连用有数数形式,不可数名词不能与不定冠词a(an)连用,没有复数形式
many+可数名词复数
much/a little+不可数名词
some, any , a lot of (lots of) 两者都可以修饰。
3、可数名词可以直接用数词来修饰
不可数名词 数词 +量词 +of + 名词
对可数名词的数量提问用How many
对不可数名词的数量提问用 How much4、不可数名词的量有以下两种表示方法:
1) some, much ,a little ,a lot of ,a bit of , plenty of 用等表示多少。
注意既可以与可数名词复数,又可以与不可数名词连用的有:plenty of ,some ,a lot of ,lots of ,most of 等。
如There is much water in the bottle .瓶中有很多水。
I'll tell you much good news.我要告诉你许多好消息。
We should collect some useful information我们应该收集一些有用的消息。
2) 用单位词表示。
用a ... of 表示。
如 a cup of ( 一杯......),a bottle of (一瓶......)
a piece of ( 一张......),a pair of shoes(一双鞋)
如two cups of tea(两杯茶),five pieces of paper(五张纸)
注意单位词后的动词单复数形式往往取决于单位词的单复数形式;千、百等数词与名词加用,表示复数时,数词仍保持单数,名词变复数。
如two hundred students(200名学生)
ten thousand trees(10000棵树)
测试点He caught a lot of fish他抓到了许多鱼(此处为许多条鱼,fish的复数仍为fish或fishes)
=He caught a lot of fishes.
The paper is about some fresh-water fishes.这篇论文是有关几种淡水鱼的。(此处fish表示不同种类的鱼,加复数词尾-es)
5、可数名词分为单数和复数。
名词单数就是该词本身,在其前面加a或an。
1)单数
如a desk(一张桌子)
an old desk(一张旧书桌)
2)复数:要表示一个以上概念时,要用名词复数形式
规则变化
1)一般情况下加-s
如book--books(书) desk--desks(书桌)
2)以s ,x ,ch , sh结尾加-es
如box--boxes(盒子) bus--buses(公共汽车)
注意①以 th 结尾加-s, month--months
②stomach--stomachs
3)以辅音字母+结尾,变y为i再加- es。
如city--cities(城市) country--countries(国家)
注意以元音+y,直接加s。如:day--days(天),boy--boys(男孩)
4)以f或fe结尾,复数变f或 fe 为v再加-es
如knife-knives(书) , half-halves(一半)
(thief ,wife ,life ,shelf ,knife ,leaf ,self ,half ,wolf)

英语语法的学习,有利于我们更好的掌握英语基础。下面就让读文网小编给大家分享一些六年级英语语法知识点吧,希望能对你有帮助!
(一)、形容词的比较级
1、形容词比较级在句子中的运用:两个事物或人的比较用比较级,比较级后面一般带有单词than。比较级前面可以用more, a
little来修饰表示程度。than后的人称代词用主格(口语中可用宾格)。
2.形容词加er的规则:
⑴ 一般在词尾加er ;
⑵ 以字母e 结尾,加r ;
⑶ 以一个元音字母和一个辅音字母结尾,应双写末尾的辅音字母,再加er ;
⑷ 以“辅音字母+y”结尾,先把y变i,再加er 。
3.不规则形容词比较级:
good-better, beautiful-more beautiful
(二)副词的比较级
1.形容词与副词的区别 (有be用形,有形用be;有动用副,有副用动)
⑴在句子中形容词一般处于名词之前或be动词之后
⑵副词在句子中最常见的是处于实义动词之后
2.副词比较级的变化规则基本与形容词比较级相同 (不规则变化:well-better, far-farther)
句法
1.陈述句
(1)肯定句:是指用肯定的语气来陈述的句子,如:I’m a student. She is a doctor. He works in a hospital.
There are four fans in our classroom. He will eat lunch at 12:00. I watched TV yesterday evening.
(2)、否定句:含有否定词或表示否定意义词的句子,如:I’m not a student. She is not (isn’t) a doctor.
He does not (doesn’t) work in a hospital. There are not (aren’t) four fans in our classroom.
He will not (won’t) eat lunch at 12:00. I did not (didn’t) watch TV yesterday evening.
2. 疑问句
一般疑问句:是指询问事实的句子,此类句子必须用“yes”,或“no”来回答。
特殊疑问句:以特殊疑问词(what , where , who , which , when , whose , why , how等)开头引导的句子。此类句子应该
问什么就答什么,不能用“yes 、no”来回答。
3.There be句型
There be 句型与have, has的区别
1、There be 句型表示:在某地有某物(或人)x kb 1.c om
2、在there be 句型中,主语是单数,be 动词用is ; 主语是复数,be 动词用are ; 如有几件物品,be 动词根据最*近be 动
词的那个名词决定。
3、there be 句型的否定句在be 动词后加not , 一般疑问句把be 动词调到句首。
4、there be句型与have(has) 的区别:there be 表示在某地有某物(或人);have(has) 表示某人拥有某物。
5、some 和any 在there be 句型中的运用:some 用于肯定句, any 用于否定句或疑问句。
6、and 和or 在there be句型中的运用:and 用于肯定句, or 用于否定句或疑问句。
7、针对数量提问的特殊疑问句的基本结构是:
How many + 名词复数 + are there + 介词短语?
How much + 不可数名词 + is there + 介词短语?
8、针对主语提问的特殊疑问句的基本结构是:
What’s + 介词短语?

掌握好英语的每个语法知识点是很重要的。下面是读文网小编收集整理的中考英语语法知识点以供大家学习。
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)
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. )
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。

英语的学习需要大量的练习。下面是读文网小编收集整理的高二英语必修5Unit3的语法练习题目及其参考答案以供大家学习。
Ⅰ.单项填空
1.(2009年高考福建卷)________ not to miss the flight at 15∶20,the manager set out for the airport in a hurry.
A.Reminding
B.Reminded
C.To remind
D.Having reminded
解析:选B。句意:有人提醒经理不要错过15∶20的航班,他匆忙出发去了机场。本题考查非谓语动词作状语。主句主语the manager与remind之间的关系为逻辑上的动宾关系,故排除A、C、D三项,因为这三项表主动,而只有B项表被动。
2.(2010年高考湖南卷)Dina,________ for months to find a job as a waitress,finally took a position at a local advertising agency.
A.struggling B.struggled
C.having struggled D.to struggle
解析:选C。此处分词短语作时间状语,其逻辑主语Dina与struggle为主动关系,故排除B项。由句中的finally可知非谓语动词表示的动作发生在句中谓语took a position之前,故用现在分词的完成主动式。
3.(2009年高考江西卷)________ the right kind of training,these teenage soccer players may one day grow into international stars.
A.Giving B.Having given
C.To give D.Given
解析:选D。考查非谓语动词。如果把句子补充完整应该是:If they are given the right kind of training,可知主语they即these teenage soccer players与give之间是被动关系,所以用过去分词。而A、B、C三项都不表示被动含义。
4.(2009年高考四川卷)________ many times,he finally understood it.
A.Told B.Telling
C.Having told D.Having been told
解析:选D。考查非谓语动词。tell与主语之间的关系是被动关系,故排除表示主动意义的B项和C项。由状语many times可知tell这一动作在谓语动词understand之前发生过多次,所以用having been done来表示被动和完成。
5.(2009年高考天津卷)________ by the advances in technology,many farmers have set up wind farms on their land.
A.Being encouraged B.Encouraging
C.Encouraged D.Having encouraged
解析:选C。考查非谓语动词。由于主语many farmers和作状语的encourage之间是被动关系,排除表示主动意义的B项和D项。而being encouraged除表示被动外,还表示进行。农民们显然不是正在受到科技进步的鼓舞,故排除A项。
6.(2011年汕头高二检测)________ in 1636,Harvard is one of the most famous universities in the United States.
A.Being founded B.It was founded
C.Founded D.Founding
解析:选C。分析句子结构可知应选考查非谓语动词形式作状语的,排除B项,另外found与Harvard之间为被动关系,应用过去分词形式作状语,故选C。
7.(2011年晋中高二检测)________ as the “First Lady of Speech”,Dr Lillian Glass is recognized as one of the world’s leading experts on communication skills.
A.Knowing B.Having known
C.Known D.To be known
解析:选C。 be known as被称为……。Dr Lillian Glass与know之间为被动关系,应用过去分词形式作状语。A、B表主动,应排除;D项表将来,也可排除。
8.________ more attention,the trees could have grown better.
A.Given B.To give
C.Giving D.Having given
解析:选A。考查分词作状语。句子主语the trees与give之间是被动关系,而四个选项中只有A项表示被动意义,故答案选A。Given more attention相当于一个条件状语从句If the trees were given more attention。
9.________ in thought,he almost ran into the car in front of him.
A.Losing B.Having lost
C.Lost D.To lose
解析:选C。考查分词作状语。句意:由于陷入沉思,他差一点撞到前面的车上。be lost in thought为固定搭配,意为“陷入沉思”。过去分词短语lost in thought在句中作原因状语。
10.The research is so designed that once ________ nothing can be done to change it.
A.begins B.having begun
C.beginning D.begunw
解析:选D。考查分词作状语。句意:这项调查研究事先计划的如此完好,以至于一旦开始,什么也无法改变它。begin与research之间是被动关系,排除表示主动意义的A、B、C三项。once begun在句中作条件状语,它是状语从句once it is begun的省略形式。
11.Generally speaking,________ according to the directions,the drug has no side effect.
A.when taking B.when taken
C.when to take D.when to be taken
解析:选B。考查分词作状语。完整的说法应是when the drug is taken according to the directions...。由于主句的主语和从句的主语相同,因此可以省略从句的主语the drug和谓语的一部分is,故答案为B。
12.________ into use in April,2000,the hotline was meant for residents reporting water and heating supply breakdowns.
A.Put B.Putting
C.Having put D.Being put
解析:选A。考查过去分词作状语。句子的主语是the hotline与put into use“投入使用”存在被动关系,排除表示主动的B项和C项。D项表示正在投入使用,不符合语境。
13.In order not to be found,I spent the whole night ________ in my room.
A.locking B.locked
C.to lock D.lock
解析:选B。考查过去分词作状语。句意:为了不被找到,我整晚上都把自己锁在自己的房间里。lock的逻辑主语I和lock之间存在被动关系,故用过去分词作伴随状语。本题易受“spend... doing sth.句型的影响,易误选A。其实我并不是把整晚上的时间都用在了“锁”这一动作上,故排除A。
14.________,liquids can be changed into gases.
A.Heating B.To be heated
C.Heated D.Heat
解析:选C。考查过去分词作状语。句意:被加热时,液体可以变成气体。由于对于液体来说是加热的承受者,是被动的,因而选C。A项表示主动,B项表示目的,D项是谓语动词的形式。
15.Unless ________ to speak,you should remain silent at the conference.
A.invited B.inviting
C.being invited D.having invited
解析:选A。考查过去分词作状语。句意:除非受到邀请讲话,否则在大会上你应该保持沉默。invite与you之间是被动关系,排除B、D。being invited表示正在受到邀请,不符合语境。
Ⅱ.句型转换(把下列句子转变成过去分词作状语的结构)
1.If I am offered great help,I can get rid of all the difficulties.
________ ________ ________,I can get rid of all the difficulties.
答案:Offered great help
2.Because she was frightened,she asked me to go with her.

动词不定式作宾语的注意事项(2点)
1. 有些动词既可跟不定式作宾语,也可跟动名词作宾语,但含义不同: remember to do 记住要做某事
remember doing 记得曾经做过某事
forget to do忘记要做某事
forget doing 忘记曾经做过某事
stop to do 停下来去做某事
stop doing 停止做某事
go on to do 继续做另一件事
go on doing 继续做原来在做的事
I remember seeing you somewhere before.
我记得以前在哪儿见过你。
Please remember to turn off the light when you leave.
离开时请记得关好灯。
2. 不定式作宾语时,如带有宾语补足语,则要把不定式放到后面,用it作形式宾语,构成“主语+动词+it+宾补(形容词、名词)+不定式”结构。
如:He found it very difficult to get to sleep.
他发现很难入睡。
四. 动词不定式作宾语补足语
1. 后面能接to不定式作宾语补足语的动词有:ask, order, teach, tell, want, wish, help等。
The teacher told us to do Exercise 1. 老师要我们做练习一。
I want both of you to go. 我要你们俩去。
We helped her (to) repair her bike. 我们帮助她修理自行车。
2. 使役动词let, have, make及感官动词see, watch, notice, hear, feel等要以不带to的不定式作宾补。
Let’s have a rest. 我们休息一会吧。
I saw him come in. 我看见他进来了。
感官动词后既可跟不带to的不定式作宾补,也可跟v-ing作宾补,前者表示动作的全部过程已结束;后者表示动作正在进行。
I saw him come downstairs.我看见他下了楼。(说明他下楼了这件事) I saw him coming downstairs.我看见他在下楼。(说明他下楼时的情景)
五. 动词不定式作状语
Later he left home to work in different cities. 不久他离开家到不同的城市工作。 He went to see a football match. 他去看足球比赛了。
In order to catch the other students, I must work hard.
为了赶上其他同学,我必须努力学习。
六. 动词不定式作定语
不定式作定语一般放在所修饰的词的后面。
I need something to eat.
Do you have something to read?
Tom was so excited that he had no word to say.
He is really a fool only to eat.
The man to stand here just now is our English teacher.
The doctor had no way to save the patient.
注意:
(1)作定语的不定式是由及物动词组成,被修饰的名词或代词与不定式之间存在方位或方式关系需要有介词。
I am looking for a room to live in. 我正在找一间住房。(方位关系) We have many things to do experiments with.
我们有许多做实验的东西(方式关系)
(2)作定语的不定式是由“be + adj + prep”构成的动词短语。
Here there isn’t any book for me to be interested in.
We have done many things to proud of. 我们做了许多引以自豪的事。
七. 动词不定式作主语
To give is better than to receive.
To reach there on foot is impossible.
动词不定式作主语时,可以用it 代替,把实际主语不定式放在后面。 It’s better to give than to receive.
It’s impossible to reach there on foot.
It’s + adj + for sb. to do sth.
It’s not difficult for me to study English well.
It’s easy for him to work out this math problem.
在这个句型中,如果形容词与不定式的逻辑主语关系密切,并且形容词用来说明逻辑主语的性质、品质、特点等,由of引出逻辑主语。这类形容词主要有nice,kind, good, wrong, right等。
八. 动词不定式和疑问词连用
动词不定式可以和疑问词what, which, how, where, when连用,构成不定式短语,可以作主语、宾语、表语、宾语补足语等。
How to do is still a question.
Have you decided when to leave?
