II. 知识归纳

(一)I don't think that…

在含宾语从句的复合句中,按原句意思应放在从句中的否定词有时转移到主句的谓语中,这种现象叫做否定转移(Transferred Negation)。主句中的谓语动词是think,believe,feel,suppose,guess,appear,seem,expect,imagine等表示“看法”“感觉”的动词时,常用否定转移。e.g.I don't think(that)you need worry. (I think you needn't worry.)我认为你无须着急。

I don't believe(that)you two have met,have you? (I believe you two haven't met.)我相信你们俩还未见过面,是吗?

使用否定转移时,还须注意以下几点:

1.并不是所有表示“看法……感觉”的动词都能用于否定转移,如hope,trust,be afraid,fear等动词就不能用于这种形式。

2.下列情况,上述用于否定转移的动词也不宜用否定转移结构。

(1)上述动词意义发生变化时: e.g.Let us suppose A doesn't equal B.咱们假定A不等于B。

(2)当主句谓语有do,does等强调词时: e.g.I do think you shouldn't go there.我实在认为你不应该去那里。

(3)当主句中有情态动词或副词修饰时: e.g.I can't believe that they are married.我不相信他们结婚了。

I often think that I'm not fit for the job.我常想我不适合这个工作。

(4)当句子以疑问句形式出现时: Do you think that it is true?你认为这不对吗?

(5)当主句谓语动词与另一个动词并列时:

e.g.I should not only think but also be sure that it won't rain tonight.我不仅该认为而且该肯定今晚天不会下雨。

(6)当宾语从句中是not/never…too…(越……越好,无论怎样……也不过分)结构时,不能用否定转移结构,因为这时整个句子不是否定的,而是肯定的。e.g.I think he can not do the work too well.我想他干得越出色越好。

(7)当从句中含有every,all,both,each,many等词时: e.g.I suppose both answers are not right.

I don't suppose both answers are right.我不是认为两个答案都对。

3.从句中除not以外的否定词(如never,no,hardly,little,few,seldom,scarcely等)不能直接转移到主句中去。

e.g.I thought he had never come here. I never thought he had come here.本句意是:I didn't think he had ever come here.

4.否定转移的句子构成反意疑问句时,如果主句的主语是第一人称,附加问句部分要与宾语从句取得一致。

e.g.I don't think that you can get there in time,can you?我认为你不能及时到达那里,你能不能呢?

I think that they are coming tomorrow aren't they?我认为他们明天来,对吗?

(二)cost的用法

1.vt.价值(多少钱),需要(多少钱);花费金钱,花费时间e.g.How much does the book cost?这本书需要多少钱?

My hat cost twenty dollars.我的帽子价值二十美元。

The journey cost me more than 50 dollars/more than ten hours.这次旅行花了我五十美元/十多个小时。

2.cost还可表示“使付出(代价),使……失去……”。

e.g.It cost me a lot of work.它使我付出了很多劳动。Careless driving cost him his life.开车不小心使他丧生。

The battle cost the king 2000 men.这次战斗使国王损失了二千人。

3.cost作名词,“费用,成本,价钱”。 e.g.She just had to pay for the cost of food.他只需付饭钱。

It was sold under cost price.那个东西赔本卖掉了。What's the cost of the car?那辆汽车得花多少钱?

(三)情态动词表推测的用法归纳:

情态动词中的must,can,could,should,ought to,may,might等都表示推测。其中must的推测性最大;can/could(should/ought to)次之;may/might最小。must表推测时只用于肯定句中;can/could用于否定句、疑问句中;may/might用于肯定句、否定句中。下面就它们的具体用法进行讲解。

1.must的用法 (1)must可以对现在、现在进行的情况进行推测。

e.g.Judging by his accent,he must be from the south.听他的口音,他一定是南方人。

此句的反意疑问句为:isn't it?(因must后是系动词be)

Tom bought a lot of apples.He must like eating apples.汤姆买了很多苹果,他一定喜欢吃苹果。

此句的反意疑问句为:doesn't he?(因must后是实义动词like)

It is eleven o'clock at night and the lights are off.They must be sleeping now.

现在已经是深夜十一点且灯都关了,他们一定是睡觉了。

此句的反意疑问句为:aren't they?(must后接的是be sleeping,是对现正在进行的情况的推测)

(2)must还可以对过去的情况进行推测,用must have done。

e.g.The ground is very wet.It must have rained last night.地面很湿,昨天晚上一定下雨了。

must have done的反意疑问句有三种情况:

①若句中含有过去的时间状语,用一般过去时完成反意疑问句。如例句的反意疑问句为:didn't it?

②若句中含有过去完成时的时间状语,用过去完成时完成反意疑问句。

e.g.We must have learned 2000 words by the end of last term,hadn't we?

③若句中不含任何时间状语,用现在完成时完成反意疑问句。

e.g.He must have gone to Beijing,hasn't he?他一定是去北京了,是吗?

2.can/could的用法

(1)can后跟动词原形;表示对现在情况的否定和疑问推测。

e.g.Mr.Li has gone to Beijing.The man at the gate can't be him.李老师去北京了,门口的那个人不可能是他。

The watch is not yours,who else's can it be?这块表不是你的,它可能是谁的呢?

(2)can/could have done是对过去发生的情况的推测。e.g.-Can they have finished the work?他们可能完成工作了吗?

-No,they haven't finished it.他们不可能完成它。

3.may/might的用法might比may更委婉、含蓄或更加不肯定。e.g.He may/might be English.他可能是英国人。

She may/might have gone to the library.她可能去图书馆了。

4.should/ought to的用法should/ought to表推测,意为“理应,应该”。

e.g.They left yesterday.They should be home by now.他们昨天就离开了,现在理应到家了。

3.worth while表示“……是值得的”,其后跟不定式或动名词均可。

The Success of McDonald's

In 1895,a man named Raymond Kroc entered a partnership(合营公司)with two brothers named McDonald.They opened a popular restaurant in California which sold food that was easy to prepare and serve quickly.Hamburgers,French fries,and cold drinks were the main food there.Kroc opened similar eating places under the same name“McDonald”,and they were an instant(立即的)success.He later took over the company,and today it is one of the most famous and successful “fast-food” in America and the world.

Why was his idea so successful? Probably the most important reason was that his timing was right.In the 1950s,most married women stayed home to keep house and take care of their children.In the 1960s,many women returned to the workplace,this meant that they had less time and energy(精力)to do housework and preparations for meals so they relied more on“TV dinners” and fast-food restaurants.Single parents also have little time to spend in the kitchen.People living alone also depend on this type of food, since cooking for one is often more trouble than it is worth.

Fast-food is not part of the diet(饮食)of all Americans.Another trend(倾向)of the 1960s,sometimes called the back-to-nature movement influenced(影响)many people to avoid(避开)food that was packaged or processed(袋装的或加工好的).This preference(偏爱)for natural foods continues to this day.

From the success of Raymond Kroc's fast-food business,we can say that social economic(社会经济)trends influence where and what we eat.

1.“Cooking for one is more trouble than it is worth” means _________.

A.cooking for several people is worth more money B.it is not necessary to take too much time to cook for one person

C.there are more problems when one person cooks

D.there are a lot of housework and preparations to do when one person cooks.

2.An idea implied(含蓄的)in the passage is that _________.

A.many married women began to work in the 1960s B.natural food is still popular today

C.fast-food is not part of the diet of all Americans D.divorce(离婚)causes people to change their eating habits

3.Americans had the back-to-nature movements _________.

A.in 1955 B.in 1950s C.in 1960s D.both in 1950s and 1960s

4.Why was McDonld's idea so successful? It was mainly because _________.

A.people living alone depend on fast-food B.single parents have little time to spend in the kitchen

C.many women returned to the workplace in 1960s D.his timing was right

5.The main idea of the passage is that _________.

A.Raymond Kroc is the most successful fast-food business owner in the world

B.Social and economic changes affect(影响)eating habits C.Fast-food is easy to prepare and serve quickly

D.Americans rat either fast-food or natural food

How To Make Friends with the Students?

Have you ever heard the saying“If you want a friend,be one”?

Here is how one teacher made friends with the girls and boys in her class on the first day of school.As the bell rang,the teacher smiled at each girl and boy.Then she said in a quiet voice(嗓音),“Good morning.How nice it is to have all of you in my class this year.I'd like to know each of you.I am sure we will enjoy working together.” Everyone felt that she meant what she said because of her sweet voice and her friendly look.

She told the girls and boys her name and wrote it on the blackboard.Then she told them some of the things she liked to do and she was hoping to do with them during the year.

Then she said to the class,“Now you know my name and the things I like and I want to know your names and the things you like.Then I will feel that I know you.”

One way of getting to know girls and boys in your class is to find out more about them.It is often to be friends with those people who have the same hobbies(爱好)with you.You play the same games and go on journeys together.
