① 数学奥赛起跑线五年级分册第13讲第6题答案

公元751年至今有1600年

② 初中英语时态和短语以及语法

(一)be动词。

1、be动词包括am, are, is。

2、be动词的用法。

am → 主语是单数第一人称(即I)。e.g. I am…

be are → 单数第二人称及所有复数。e.g. You are… The coats are…

is → 单数第三人称及不可数名词。 e.g. Your father is… The money is…

3、否定句式(即改否定句):在be动词之后+not, 句子其它部位不变。

e.g. He is not a teacher.

4、缩写形式。

①主语+be,缩写be第一个字母为 ’,再与主语合并。

e.g. you are → you’re Jack is → Jack’s

② be+not否定形式的缩写,缩写not中“o”为 ’, 再与be合并。

e.g. is not→isn’t are not→aren’t

③不能缩写的情况:this is, these are, those are, am not及缩略的肯定回答。

e.g. Yes, I am. (I’m 误)

5、含be动词句子的疑问句型转换。

①一般疑问句:将be动词提前,其它照抄不变,最后+?,读升调。(一般第一人称改为第二人称)

e.g. The man in the car is her father. → Is the man in the car her father?

I’m a middle school student. → Are you a middle school student?

②一般疑问句的肯否定回答。

肯定回答: Yes, 主语+be. 否定回答: No, 主语+be+not.

e.g. Is he old? Are you a new student? Is your father at home?

Yes, he is. Yes, I am. Yes, he is.

No, he is not.(isn’t) No, I’m not. No, he is not.(isn’t)

注意:①主语必须用代词回答;②肯定回答不能缩写;③回答第二人称,用第一人称回答。

③特殊疑问句(就划线部分提问)。

1) 方法:将句子被提问(即被划线)的部分改为相对应的疑问词,然后置于句首,接着再将be动词或情态动词提前 (置于疑问词之后),其它部分照抄不变,最后+?(即疑问词+一般疑问句?)

e.g. The man in a red cap is her brother. → Who is the man in a red cap?

I can sing English songs. → What can you do?

2) 注意:①被提问部分不能再写。

②提问动词(即提问做某事),在改句子时注意还“do”,表示做什么?

3) 相应的疑问词。

1. 事物 → what e.g. That is a cat. → What is that?

2. 地点 → where He is at home? → Where is he?

3. 人 → who The man is his father. → Who is the man?

4. 怎样(程度,方式) → how She’s fine. → How is she?

He can go to school by bus. →How can he go to school?

5. 年龄 → how old Our grandpa is 80. → How old is your grandpa?

6. 班级 → what class We are in Class 2, Grade 1. → What class are you in?

7. 数字 → what My phone number is 2212121→What’s your phone number?

8. 颜色 → what color His car is yellow. → What color is his car?

9. 时间 → what time I can get there at six. → What time can you get there?

when I can go with you on Sunday. → When can you go with me?

10. 价钱 → how much The bag is twenty yuan. → How much is the bag?

2、代词的用法

①动作的发出者,代词用主格,(一般在句首,动词前)。 e.g. He often writes to me.

②动作的承受者,代词用宾格,(一般在句末,动词后、介词后)。

e.g. Let’s ask him. Let’s play with them.

③物的主人,用物主代词。(即代词所有格)

形容词性物主代词后一定要带物,不能单独使用,一般用在名词前。

e.g. This is their classroom. That is my bike. It is her red coat.

(三)所有格:表示物或人的“所属”关系。

1、名词所有格的形式:

① 名词之后直接+’s e.g. Mary―Mary’s Kate―Kate’s

② 以s结尾的名词只加 ' e.g. students―students’

2、以上形式一般只用于有生命的名词,但也可用于表示时间、距离、国家、地点等无生命的名词。e.g. today’s newspaper; an hour’s walk; China’s city

3、注意: ①表示两者或多者共有,在最后一个名词+ ’s。

e.g. Mike and Jim’s room.(共用,用单数)

②如果不是共有,指各有,则各词都应+’s。

e.g. Mike’s and Jim’s rooms. (各有,用复数)

4、表示无生命的名词所有格用of短语表示,但注意词序与汉语习惯不同,形式为:名词+of+名词(前者属于后者)。

e.g. the door of the room. 那房间的门 the picture of my family. 我的家庭的照片

5、注意:有时’s 结构可以转化为of 短语。(对等)

e.g. his father’s friends → the friends of his father.

the girl’s new computer → the new computer of the girl.

the dog’s name → the name of the dog

但不是所有of 结构都有对等的’s结构。因为’s 只用于有生命的词。

(四)名词的数。

1、名词的概念:名词是指表示人、事物、地点或抽象概念名称的词,

如:teacher, school, morning, thanks, ty.

名词按其所表示的事物的性质分为可数名词和不可数名词。

2、可数名词。

1)可数名词是指可以用数目计算是名词,有单复数两种形式。

可数名词包括个体名词:e.g. apple , student.

集体名词:e.g. class people

2)用法: ① 单数名词前可用a, an修饰;

② 之前可以直接用数词;

③ 之前可用a lot of, lots of,many, some等修饰;

④ 提问其数量用How many + 复数名词;

3)可数名词的复数形式: 英语名词复数的构成有规则变化和不规则变化两种形式。

A 规则变化:

① 一般在单词的结尾直接+s; book ― books

② 如果单词以s, x, ch, sh等结尾,+es; bus ― buses

③ 若以辅音字母+y结尾,变y为i+es; city ― cities story ― stories

④ 以f或fe结尾,变f或fe为ves;wife ― wives knife ― knives

⑤ 以o结尾, tomato — tomatoes; photo— photos;

⑥ 两个名词用在一起构成合成名词变复数时,只把合成名词的主体名词变成复数。 e.g. banana trees

⑦ 但是以woman, man等名词与其后面的名词构成合成名词变复数时,里面所含的成分全部要变成复数。three women teachers

B 不规则变化:

① 单复数同形 Chinese中国人 Japanese日本人

② 只作复数 trousers clothes chips thanks people(人们)

③ 特殊变化:

man―men woman―women foot―feet child―children

3、不可数名词。

1)不可数名词是指不可以用数目计算是名词,它一般没有复数形式。

不可数名词包括物质名词:broccoli. 抽象名词:work, homework.

2)用法:① 不用a, an修饰;

② 前面可用a lot of, lots of, much, some, a little等修饰;

③ 作主语时,都视为单数;

④ 提问其数量时用How much;

e.g. How much money do you have?

(五)祈使句:

1、祈使句表示请求,命令,建议等,它没有主语(其实是省略了主语you),

以动词开头,动词要用原形,句末用“!”或“.”,读降调。有时为了使语气比较委婉,常在句首或句末加上please.在句末时要用逗号隔开。

e.g. Sit down, please! Let’s go to school.

2、祈使句的否定形式:

一般在句首加Don’t. e.g. Play the piano. → Don’t play the piano.

(七)一般现在时。

1、一般现在时的用法:

①表示现在的状态或特征,谓语动词一般是be。

e.g. They are at work. She is very old.

②表示经常性或习惯性动作,谓语动词一般是实义动词。

e.g. We go to school from Monday to Friday.

③表示主语具备的性格和能力。

e.g. I like swimming. Do you speak English?

④普遍真理。e.g. Two plus four is six. The earth goes around the sun.

2、一般时态(一般现在时)的谓语形式。

①动词be 的人称变化: (略)

②实义动词的变化:主语为单数第三人称,实义动词应+s或es。

(其变化类同于名词的复数形式)

主语为其他人称时,实义动词不变。

3、一般现在时的句型变化。

1)be动词的句式:(略)

2)实义动词的句式:改否定句及疑问句都应借助助动词do或does。

(当主语为单数第三人称时,用does, 同时应将其后的谓语动词还原形)。

① 改否定句:在实义动词之前+don’t或doesn’t.

e.g. We go to school on Sundays. → We don’t go to school on Sundays.

He does his homework after supper.

→ He doesn’t do his homework after supper.

② 改一般疑问句:在句首添加Do或Does,其他照抄,最后加问号。

e.g. They speak English. → Do they speak English?

He goes home at five every day.

→ Does he go home at five every day?

③ 一般疑问句的肯否定回答。

Yes, 主语do. No, 主语don’t. Yes, 主语does. No, 主语doesn’t.

e.g. Do they speak English? Does he go home at five every day?

Yes, they do. Yes, he does.

No, they don’t. No, he doesn’t.

④ 改特殊疑问句:疑问代词+一般疑问句?(do/does+其他?)

e.g. I like to eat apple. What do you like to eat?

He goes to school every day. Where does he go every day?

4、often, five days a week, every day, on Sundays, sometimes等表示频度的状语通常位于be动词之后,实义动词之前,若句子出现频度副词,通常用一般现在时。

English Grammar:动词的时态
英语共有16种时态,根据近几年曝光的四、六级考卷分析, 时态测试重点主要有:完成时态——现在完成时、过去完成时、将来完成时;进行时态——现在进行时、过去进行时、将来进行时、完成进行时;一般时态。

一、一般时态

1、一般现在时

(1)一般现在时表示没有时限的持久存在的动作或状态或现阶段反复发生的动作或状态,常和副词 usually,often,always sometimes, regularly,near,occasionally,every year, every week 等连用。例如:

三、完成时态

完成时态通常表示已完成或从事的动作。它可分为:

1. 现在完成时

(1)现在完成时用来表示对目前状况仍有影响的,刚刚完成的动作(常与yet,already,just连用),或者过去某一时刻发生的,持续到现在的情况(常与for,since连用)。例如:

(1)This is one of the rarest questions that have ever been raised at such a meeting.

(2)There was a knock at the door. It was the second time someone had interrupted me that evening.

2. 过去完成时

另外两种表示“过去想做而未做的事”的表达方式是:

1)was / were + to have done sth, 例如:

We were to have come yesterday, but we couldn’t.

2)intended (expected, hope, meant, planned, supposed, wished, wanted, desired) + to have done sth, 例如:

(3)将来完成进行时表示在将来某一时刻之前开始的一个动作或状态一直延续到将来某一时刻。例如:

By the time you arrive tonight, she will have been typing for hours.

四:时态一致

时态一致是英语四、六级考试的一个重要内容。通常应由主句谓语的时态决定从句的谓语时态。一般原则是:

1、当主句谓语使用现在时或将来时,从句的谓语根据具体情况使用任何时态

He says that he lives in Wuhan.

We hope that there will be many people at your party today.

“Did you hear that Bill finally sold the house?” “Yes, but I don’t know who bought it.”

“There’s a lot of excitement on the street.”

“There certainly is. Do you suppose the astronauts have returned?”

2、当主句谓语使用过去时的时候,从句的谓语必须使用过去范围的时态

He said he was writing a novel.

The teacher wanted to know when we would finish the experiment.

He said his father had been an engineer.

3、当从句是表示没有时间概念的真理时,从句的谓语应使用一般现在时。例如:

The teacher told them since light travels faster than sound, lightning appears to go before thunder.

注:在此种情况下,即使主句谓语用了过去式的各种时态,从句谓语也应用一般现在时。

4、从句谓语只能用虚拟语气的情况

利用时态一致原则确定从句动词时态时,还应注意,若主语动词是表示命令、请求、要求、建议、劝告等的动词,从句谓语只能用虚拟语气,不能遵循时态一致原则。例如:

We insisted that we do it ourselves.

动词的语态

语态也是动词的一种形式,英语有两种语态:主动语态和被动语态。主动语态表示主语是动作的执行者,而被动语态表示主语是动作的承受者。

1)We use electricity to run machines. (主动语态)

2)Electricity is used to run machines. (被动语态)

1. 不能用于被动语态的动词和短语

(1)在英语中,不及物动词不能用于被动语态,但有些不及物动词(包括短语)容易引起误用。如:appear, belong, belong, die, escape, fall, happen, last, remain, succeed, occur, come true, take place, consist of。

(2)某些表示状态或特征的及物动词,如:become, contain, cost, fit, have, resemble, suit也没有被动语态。

2. 被动语态的时态形式

常用的被动语态有表1 所列的几种时态形式。

表1

时间 一般时 进行时 完成时

现在 am asked am being asked

is asked is being asked

are asked are being asked

过去

was be asked was being asked

were be asked were being asked

将来 shall be asked shall have been asked

will be asked will have been asked

过去 should be asked should have been asked

将来 would be asked would have been asked

3. 短语动词的被动语态

短语动词转换为被动语态时,通常被看作是一个动词,后面的介词或副词不能拆开或省略。例如:

1)So far no correct conclusion has arrived at.

2)All the rubbish should be got rid of.

4.“get + -ed分词”的被动语态

“get + -ed分词”结构强调动作的结果,而非动作本身,常用来表示突发性的,出乎意料的偶然事件。例如:

The boy got hurt on his way home from work.

另外,“get + -ed分词”还可用于谈论为自己做的事,是主动的行为而不是被动的行为。例如:

get dressed(穿衣服) get divorced(离婚)

get engaged(订婚) get confused(迷惑不解)

get lost(迷路) get washed(洗脸)

get married(结婚)

5. 能带两个宾语和复合宾语的动词改为被动语态

(1) 能带两个宾语的动词改为被动语态时,一次只能由一个宾语作主语,另一个宾语被保留下来。例如:

1)We showed the visitors our new procts.(主动语态)

2)The visitors were shown our new procts.(被动语态)

3)Our new procts were shown to the visitors.(被动语态)

(2)能带复合宾语的动词改为被动语态时,原来的宾语补足语变为主语补足语。例如:

1)The teacher appointed him League secretary.(主动语态)

2)He was appointed League secretary.(被动语态)

6. 被动语态与系表结构的区别

(1)The novel was well written.(系表结构)

(2)The novel was written by Diskens.(被动语态)

7. 少数动词的主动语态有时有被动的意思

例1:The book is selling remarkably well.

例2:The song sounds very beautiful.

能这样用的动词还有read(读起来),clean(擦起来),wash(洗起来),write(写起来)。

例3:My watch needs cleaning. (= My watch needs to be cleaned).

能像need这样用的动词还有:want, require, deserve, do, owe, bind等。

例4:The meat is cooking.

例 5:The book written by the professor is printing.
