㈠ 求初中英语基本句型,基本结构
关于名词,我们必须掌握名词的数,名词的格。
单数可用a、an来修饰可数名词单数,在元音发音开头的单词前用an,而不是a
1.复数的构成方法:(1)一般在复数名词后加s,如:dog--dogs。
(2)以s、x、ch、sh结尾的名词加es,如:watch--watches。
(3)以辅音字母加y结尾的名词,变y为i加es, 如:country--countries。
请区别:如果是元音字母加y结尾的名词,则只须加s。 如:monkey--monkeys。
(4)以o结尾的名词,只有potato(土豆),tomato(西红柿)加es构成复数。
(5)以f、fe结尾的名词,变f、fe为v再加es, 如:knife--knives。
2.单复数形式相同的词:sheep--sheep,fish--fish Chinese--Chinese,Japanese--Japanese
3.特殊变化的单词有:(1)tooth--teeth,foot--feeth
(2)man--men,woman--women,policeman--policemen,Frenchman--Frenchmen
请区别:German(德国人)—Germans (3)child—children
4.常以复数形式出现的名词:people(人),clothes(衣服),trousers(裤子) glasses(眼镜) ,这些名词作主语时,同学们应特别注意它们的谓语,用复数。 如:My clothes are (be) newer than yours.
5.有些名词看似复数形式,实际上是单数。这一点是同学不易掌握的,应特别加以记忆。如:news(消息),maths(数学),physics(物理) No news is good news.
6.可用how many,many,a few,few,a lot of,lots of,some,any等来修饰可数名词复数。 How many are there in your pencil-box?(knife)
不可数名词:1.常见的不可数名词有:water,rice,fish,meat,等。应特别记medicine,news,work,homework,housework,money,chalk,weather,cotton,wood.
2.不可数名词无复数,作主语时常看成单数。如:Some bread__________over there.(be)
3.常用how much,much,a little,little,a lot of,some,any等来修饰不可数名词。
4.常用a piece of,a cup of等来表示不可数名词的量。如要表达“两片面包”这样的意义,bread仍为不可数名词,不加s,而piece则可加s。即:twopiecesof bread
请区别:可数名词也可用量来表示, 如:三箱苹果three boxes of apples
例: 1、These two pieces of bread __________over there.(be)
2、Could I have three ___________,please?
A.piece of breadB.piece of breadsC.pieces of bread D.pieces of breads
名词的格 名词所有格的构成方法,在名词后加“ 's”。如:Tom→Tom's译为“…的”,若遇上以s结尾的复数名词,则在s后加“ '”即可。如:Teachers'Day , twoweeks'holiday,而不以s结尾的复数名词的所有格,仍按惯例加's 。如:Children's Day
关于名词所有格,应掌握以下几点:

㈡ 初中英语句型结构
基本句型一: S+V (主+谓)
基本句型二: S+V+P (主+谓+表)
基本句型三: S+V+O (主+谓+宾)
基本句型四: S+V+o+O (主+谓+间宾+直宾)
基本句型五: S+V+O+C (主+谓+宾+宾补)
基本句型 一
此句型的句子有一个共同特点,即句子的谓语动词都能表达完整的意思。
这类动词叫做不及物动词,后面可以跟副词、介词短语、状语从句等。
S+V (不及物动词)
1. The sun │was shining.
2. The moon │rose.
3. The universe │remains.
4. We all │breathe, eat, and drink.
5. Lucy and Mary │get up early every morning.
6. What he said │does not matter.
7. They │had talked for half an hour when I came in.
8. His parents │have worked in the factory for more than ten years.
基本句型 二
此句型的句子有一个共同的特点:句子谓语动词都不能表达一个完整的意思,必须加上一个表明主语身份或状态的表语构成复合谓语,才能表达完整的意思。这类动词叫做连系动词。系动词分两类:be, look, keep, seem等属一类,表示情况;get, grow, become, turn等属另一类,表示变化。be 本身没有什么意义,只起连系主语和表语的作用。其它系动词仍保持其部分词义。
S+V(是系动词)+ P
1. This │is │an English-Chinese dictionary.
2. The dinner │smells │good.
3. He │fell │in love.
4. Everything │looks │different.
5. He │is growing │tall and strong.
6. The trouble │is │that they are short of money.
7. Our well │has gone │dry.
8. His face │turned │red.
附:
联系动词(Link Verb)本身有词义,但不能单独用作谓语,后边必须跟表语(亦称补语),构成系表结构说明主语的状况、性质、特征等情况。
有些系动词又是实义动词,该动词表达实义时,有词义,可单独作谓语,例如:
He fell ill yesterday.他昨天病了。(fell是系动词,后跟补足语,说明主语情况。)
He fell off the ladder. 他从梯子上摔下来。fell是实义动词,单独作谓语。
1)状态系动词
用来表示主语状态,只有be一词,例如:
He is a teacher. 他是一名教师。(is与补足语一起说明主语的身份。)
2)持续系动词
用来表示主语继续或保持一种状况或态度,主要有keep, rest, remain, stay, lie, stand, 例如:
He always kept silent at meeting. 他开会时总保持沉默。
This matter rests a mystery. 此事仍是一个谜。
3)表像系动词
用来表示"看起来像"这一概念,主要有seem, appear, look, 例如:
He looks tired. 他看起来很累。
He seems (to be) very sad. 他看起来很伤心。
4)感官系动词
感官系动词主要有feel, smell, sound, taste, 例如:
This kind of cloth feels very soft. 这种布手感很软。
This flower smells very sweet. 这朵花闻起来很香。
5)变化系动词
这些系动词表示主语变成什么样,变化系动词主要有become, grow, turn, fall, get, go, come, run.
He became mad after that. 自那之后,他疯了。
She grew rich within a short time. 她没多长时间就富了。
6)终止系动词
表示主语已终止动作,主要有prove, turn out, 表达"证实","变成"之意,例如:
The rumor proved false.这谣言证实有假。
The search proved difficult.搜查证实很难。
His plan turned out a success. 他的计划终于成功了。(turn out表终止性结果)
基本句型 三
此句型句子的共同特点是:谓语动词都具有实义,都是主语产生的动作,但不能表达完整的意思,必须跟有一个宾语,即动作的承受者,才能使意思完整。这类动词叫做及物动词。
S+V(及物动词)+O
1. Who │knows │the answer?
2. She │smiled │her thanks.
3. He │has refused │to help them.
4. He │enjoys │reading.
5. They │ate │what was left over.
6. He │said │"Good morning."
7. I │want │to have a cup of tea.
8. He │admits │that he was mistaken.
基本句型 四
此句型的句子有一个共同特点:谓语动词必须跟有两个宾语才能表达完整的意思。这两个宾语一个是动作的直接承受者,另一个是动作的间接承受者。
通常这一间接承受者用一个介词来连接,当动作的间接承受者在动作的直接承受者之前时,这一介词往往被省略。
S +V(及物)+o(多指人)+O(多指物)
1. She │ordered │herself │a new dress.
2. She │cooked │her husband │a delicious meal.
3. He │brought │you │a dictionary.
4. He │denies │her │nothing.
5. I │showed │him │my pictures.
6. I │gave │my car │a wash.
7. I │told │him │that the bus was late.
8. He │showed │me │how to run the machine.
基本句型 五
此句型的句子的共同特点是:动词虽然是及物动词,但是只跟一个宾语还不能表达完整的意思,必须加上一个补充成分来补足宾语,才能使意思完整。
S+V(及物)+O(宾语)+C(宾补)
1. They │appointed │him │manager.
2. They │painted │the door │green.
3. This │set │them │thinking.
4. They │found │the house │deserted.
5. What │makes │him │think so?
6. We │saw │him │out.
7. He │asked │me │to come back soon.
8. I │saw │them │getting on the bus.
但常用的英语句子并不都象基本句型这样简短,这些句子除了基本句型的成分不变外,通常是在这些成分的前面或后面增加一些修饰语(modifier)而加以扩大。这些修饰语可以是单词(主要是形容词、副词和数词),也可以是各种类型的短语(主要是介词短语、不定式短语和分词短语)。下面以基本句型五为例:
We found the hall full. 我们发现礼堂坐满了。
We found the great hall full of students and teachers. 我们发现大礼堂坐满了学生和教师。
We found the great hall full of students and teachers listening to an important report.
我们发现大礼堂坐满了学生和教师,在听一个重要报告。
We found the great hall full of students and teachers listening to an important report made by a comrade from the People's Daily on current affairs in East Europe.
我们发现大礼堂坐满了学生和教师,在听人民日报的一位同志作有关东欧局势的重要报告。
不同的动词使用的句型也不尽一样,因此在学习动词时,应掌握动词的类型。以 get 为例:
He's getting angry. (S V C)
He got through the window. (S V M)
You'll get a surprise. (S V O)
He got his shoes and socks wet. (S V O C)
He got himself into trouble. (S V O M)
He got her a splendid present. (S V 0 O)
在句子中词类和词的位置也影响句子的句型和意思:
I found the book easily.我很容易地找到了这本书。(S V O M)
I found the book easy. 我觉得这本书很容易。 (S V O C)
I have to do something. 我得做点事。
I have something to do. 我有点事做。

㈣ 初中英语八大时态基本结构
初中英语八大时态基本结构:

㈤ 初中英语 五种基本句子结构
你好,很高心为你解答
英语的基本成分有六种:主语(subject)、谓语(predicate)、表语
(predicative)、宾语(object)、定语(attribute)和状语(adverbial)。
英语句子成分中,有些具有形态标志。如第一人称代词作主语就用主格“I”,
作宾语用宾格“me”,作定语用所有格“my”。这些形态变化对分析辨认成分
很有帮助。
汉语与英语就句子成分表面上看来差不多,实际上有不少差别。例如:
(1) Xiao Li went to bed as soon as he came home.
小李回家后, 立刻就睡觉了。
(2) I'll go when I have had my dinner.
我吃了饭就去。
在英语中,同一个主语在第二次出现时不能省略,必须把每个谓语所陈述的对象都表示出来。而在汉语中,同一个主语在句中第二次出现时,就可以省
略。如例(1)中,汉语说“小李回家后立刻就睡觉了”,省去了第二个分句
的主语,倒可以避免造成误解。若将第二次出现的主语补出来,说成“小李回
家后,他立刻就睡觉了”。听的人反而可能把那个“他”误会成另一个人。
英语五种基本句型列式如下:
基本句型一: S+V (主+谓)
基本句型二: S+V+P (主+谓+表)
基本句型三: S+V+O (主+谓+宾)
基本句型四: S+V+o+O (主+谓+间宾+直宾)
基本句型五: S+V+O+C (主+谓+宾+宾补)

Your mistakes should be corrected right now. 你应该现在就改正你的错误。

Your homework can be handed in tomorrow. 你的家庭作业可以明天交。
二、 怎样把主动语态改成被动语态?
把主动语态改为被动语态非常简单,可以遵循以下几个步骤:
1. 先找出谓语动词;
2. 再找出谓语动词后的宾语;
3. 把宾语用作被动语态中的主语;
4. 注意人称、时态和数的变化。
例:1. Bruce writes a letter every week. →A letter is written by Bruce every week. 布鲁斯每星期写一封信。
2. Li Lei mended the broken bike this morning. →The broken bike was mended by Li Lei this morning. 李雷今天上午在修理坏的自行车。
3. He has written two novels so far. →Two novels have been written by him so far. 至今他已写了两部小说。
4. They will plant ten trees tomorrow. →Ten trees will be planted by them tomorrow. 他们明天将要种植十棵树。
5. Lucy is writing a letter now. →A letter is being written by Lucy now. 露西正在写信。
6. You must lock the door when you leave. →the door must be locked when you leave. 当你离开的时候你必须把门锁上。
三、 使用被动语态应注意的几个问题:
1. 不及物动词无被动语态。
What will happen in 100 years?一百年里会发生什么事?
The dinosaurs disappeared about 65 million years ago. 约65万年前恐龙灭绝。
2. 有些动词用主动形式表示被动意义。
This pen writes well. 这支钢笔很好写。
This new book sells well. 这本新书卖的很好。
3. 感官动词或使役动词使用省略to的动词不定式,主动语态中不带to ,但变为被动语态时,须加上to。
例:Make somebody do something →somebody+ be +made to do something
See somebody do something →somebody +be +seen to do something
A girl saw my wallet drop when she passed by. →My wallet was seen to drop by a girl when she passed by. 一个女孩看到我的钱夹掉了,当她经过的时候。
The boss made the little boy do heavy work. →The little boy was made to do heavy work by the boss. 这个老板让这小男孩干重活。
4. 如果是接双宾语的动词改为被动语态时,直接宾语(物)做主语,那么动词后要用介词,这个介词是由与其搭配的动词决定。
He gave me a book. →A book was given to me by him. 他给了我一本书。
He showed me a ticket. →A ticket was shown to me by him. 他给我展示了一张票。
My father bought me a new bike. →A new bike was bought for me by my father. 我父亲给我买了一辆新自行车。
5. 一些动词短语用于被动语态时,动词短语应当看作一个整体,而不能丢掉其中的介词或副词。
We can’t laugh at him. →He can’t be laugh at by us. 我们不能嘲笑他。
He listens to the radio every day. →The radio is listened to by him every day. 他每天都收听广播。
The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.这护士在照顾这个虚弱的男人。
