[主观题]

Because we can feel that things are heavy, we think of weight as being a fixed quality in

an object, but it is not really fixed at all. If you could take a one pound packet of butter 4,000 miles out from the earth, it would weigh only a quarter of a pound.

Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space? The reason is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4,000 miles from the center (in other words the radius[半径] of the earth is 4,000 miles). When we took the butter 4,000 miles out, it was 8,000 miles from the center, which is twice the distance.

If you double the distance between two objects, their gravitational attraction decreases (减少) two times two. If you treble (成三倍) the distance, it gets nine times weaker (three times three). If you take it four times as far away, it gets sixteen times weaker (four times four ) and so on.

The best title for this passage is______.

A.The Earth Weight

B.Weight in Space

C.Changing Weight on the Earth

D.Weight on and off the Earth

第5题

Of all systens of symols, language is the most highly developed. It has been ponted out that human beings, by agreement, can make anything stand for anything. Human beings have agreed, in the course of centuries of mutual (相互的) depenncy, to let the vrious n0that they can produce with their lungs. throats, tongues, teeth, and lis systematically stand for certain happenings in their nervous system. We call that system of agreements language.

There is no necessary connection between the symbol and that which it stands for. Just as social positions can be symbolized by feathers worn on the head, by gold on the watch chain, or by a thousand other things according to the culture we live in, so the fact of being hungry can be symbolized by 2 thousand dfferett noises according to the culture we live in.However obvious these facts may appear at first glance. they are actually not so obvious as they seem except when we take special pains to think about the subject. Symbols and the things they stand for are independent of each other, yet we all have a way of feeling as if and sometimes acting as if there were necessary connections. For example, there are people who feel that foreign languages are unreasonable by nature: foreigners have such funny names for things, and why can't they call things by their right names? This feeling exhibits itself most strongly in those English and American tourists who seem to believe that they can make the natives of any county understand English if they shout loud enough Like the lttle boy who is reported to have said:“Pigs are clled pigs because they are such dirty ani

mals,”they feel that the symbol is inherently (内在地) connected in some way with the things symbolized.

1.Language is a highly developed system of symbols because human beings.()

A. have made use of language for cenuries

B. use our nervous system to support language

C. have made various noises stand for any events

D. can make anything stand for anyting by agrement

2.What can we conclude fom Paragraph2? ()

A. Different noises may mean dfferet things.

B. Our culture determines what a symbol stands for.

C. The language we use symboizes our social positions.

D. Our social positions determine the way we are dessed.

3.In Paragraph 3, the underlined words take special pains probably means().

A. try very hard

B. take our time

C. are very unhappy

D. feel espeialy painful

4.The example of the lite boy is used to show that.()

A. adults often learn from their young

B. “pig”is a dirty word because pigs are dirty

C. words are not connected with the things they stand for

D. people sometimes have wrong idea about how language works

5.What does the writer of this passage think of language? ()

A. appreciative

B. depreciative

C. neutral

D. unknown

How serious can we be about humor in the workplace, and how humorous can we be about the
seriousness we often find there? According to a survey, only 15 percent of workers are fired because of lack of competence.The remaining 85 percent are let go because of their inability to get along with fellow employees.When asked about the qualities of an effective employee, the answer is "humor".Why has humor become a recognized asset in the workplace? Humor facilitates communication, builds relationships, reduces stress, and promotes attendance and energy.

Humor provides a non-threatening way for an employee or employer to communicate with each other.Consider the secretary who posts the sign "I have only two speeds.If this one isn't fast enough, you're not going to like my other one." Or the somewhat scattered boss whose messy desk has the sign, "A Creative Mess is Better than Tidy Idleness." The message is clear, yet the communication is done in a light and, therefore, less stressful way.The secretary's sign makes fun at the situation, and the boss's note makes fun at himself.

Humor can also facilitate staff connection and a sense of team effort in the workplace.Bulletin boards, electronic mail, office memos, and voicemail are all mediums through which we can share humor with co-workers.Office jokes that take the seriousness of work lightly give us the opportunity to become more connected with others.

Work is often associated with stress, and stress is one of the main causes of illness and employee burnout.Humor helps relieve stress because it makes us feel good, and we can't feel good and feel stressed at the same time.At the moment we experience humor, feelings like depression, anger, and anxiety dissolve.When we laugh we feel physically better, and after laughter we feel happier and more relaxed.In addition, humor helps reduce psychological stress.

Humor wakes us up and increases our attention.An office bulletin board full of cartoons, jokes, and funny pictures is one way to invite humor into the workplace.A few moments of humor at work can lead to increased productivity.In working environments where humor is supported, a culture develops that uses humor to reduce stress.Learning to laugh at ourselves and our work lightens the workload.

1.Whether you're humorous will somehow affect ________.

A.your relationship with the boss

B.your confidence in your company

C.your hiring status at your workplace

D.your image in your colleagues' eyes

2.What's the implication of the secretary's sign?

A.Please don't worry about my speed.

B.My 1st speed is not as fast as the 2nd one.

C.My 2nd speed is slower than the 1st one.

D.Be a little patient about my speed.

3."A Creative Mess is Better than Tidy Idleness" means that ________.

A.being messy is better than being tidy

B.being messy sometimes needs creativity

C.working hard is better than idling away time

D.working creatively is better than being tidy

4.Which statement is true according to the passage?

A.Humor is a remedy for miscommunication.

B.Humor enhances better cooperation at work.

C.Humor makes people more creative.

D.Humor can be seen from various mediums.

5.What does the author want to tell us?

A.Humor is the key to work efficiency.

B.Being humorous is not that difficult.

C.Boss-and-employee relationship is enhanced by humor.

D.Humorous employees work more happily.

My home is situated in a verysmall place called the “Pearl of the Orient”. In the “Pearl
”is a twenty-story apartment building, where lies my home. Living on theeighteenth floor, I can see ferries(渡) in the harbor, planes coming in or taking off atKai Jok Airport, and, last but not least, the busy traffic down the street.Having been in the urban area, my home is filled with polluted air. There areno trees or grass around, but only tall buildings. It is noisy because of the peoplein the apartment and the frustrated drivers who keep pushing the car horns(喇叭) in the street. Thereis never a time of silence in my home.

Being with my parents andbrothers at home, I have a feeling of unity. We solve problems together, and weexperience-joy and sadness together because we understand each others feelings.Away from home, I have to be independent in thought and in action. Being aminority in America, I cannot find a person that I can go to for problems.Since we are brought up in a different environment, with different ways of lifeand views, I feel left out in this alien(,) place.

Home is where I can find similarways of life. When I go shopping, I can find clothes that Chinese people wear.I can buy things that are related to my culture. At home, I can speak my own language.I can express myself better. Communicating with others in my own language givesme a sense of closeness. This is also true when I listen to Chinese songs onthe radio. Sometimes the songs move me. When I turn on the television set, Ican see familiar faces — blackhair and dark eyes. I can see people of my own origin — in culture andin nationality. The movies reflect the real life of Chinese people and I enjoywatching them.

第10题

A funny thing happened on the way to the communications revolution: we stopped talking

to one another.

I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation.There we were walking and talking on a beautiful sunny day and…I became invisible, absent from the conversation .

The park was filled with people talking on their cell phones They were passing people wi thout looking at them, say ing hello, noticing their babies or stopping to pat their dogs.It seems that the limitless electronic voice is preferred to human contact.

The telephone used to connect you to the absent.Now it makes people sitting next to you feel absent.Recently I was in a car with three friends.The driver hushed the rest of us because he could not hear the person on the other end of his cell phone.There we were, four friends driving down the highway, unable to talk to each other because of the small thing designed to make communication easier.

why is it that the wore connected we get.The more disconnected I feel? Every advance in ommunications technology is a setback to the closeness of human interaction(互动).With email and instant message over the internet, we can now communicate without seeing or talking to one another.With voice mail, you can make entire conversations without ever reaching anyone.If my moe has a question, I just leave the answer on her machine.

As almost every contact we can imagine between human beings gets automated(自动化), the emot ional di stance index(疏远指数) goes up.Pumping gas at the station? Why say good-morning to the assistant when you can swipe you credit card at the pump and save yourself the bother of human contact? Making a deposit at the bank? Why talk to the clerk who lives in the neight when you can put your card into the ATM?

More and more, I find myself hiding behind e-mail to do a job meant for conversation.Or being relieved that voice mail picked up because I didn ’t really have time to talk.The techno logy devoted to helping me keep in touch is making me lonelier

I own a mobile phone, an ATM card, a voicemail telephone,and an e-mail account.Giving them up isn' t a choice.They are great for what they are intended to do.It' s their unitended results that make me upset.What good is all this gee-whiz technology if there is no one in the room to hear you crying out“ Gee whiz”?

21.The author’s experience of walking in a park with a frier recently made him feel()

A.unhappy

B.funny

C.wonderful

22.According to the author, human contact in a park means()

A.looking at each other and saying hello when passing

B.noticing their babies and stopping to pat their dogs

C.both A and B

23.According to the author, the more connected we get in communication technology, the () we are

A.more automatic

B.easier

C.more disconnected

24.What are the examples the author gives to explain his idea that every advance in communication technology is a setback to the closeness of human interaction?()

A.With e-mail and instant message over the Internet.We can now communicate without seeing or talking to one another.

B.With voice mail, you can make entire conversations.without ever reaching anyone.

C.Both A and B

25.What is the unintended result of communication technology, according to the author?()

A.It makes communication easier and conversation possible everywhere.

B.It actually reates a distance between people instead of bringing them together.

C.It makes every contact between human beings automatic and makes people feel connected.

Passage Three

My husband and children feel very happy to live here. They can't see that we live on a dirty street in a dirty house among people who aren't good. They can't see that our neighbors have to make happiness out of all this dirt. I decided that my children must get out of this. The money that we've saved isn't nearly enough.

The McGaritys have money but they are so proud. They look down upon the poor The McGarity girl just yesterday stood out there in the street eating from a bag of candy while a ring of hungry children watched her. I saw those children looking at her and crying in their hearts; and when she couldn't eat any more she threw the rest down the sewer (下水道). Why? Is it only because they have money? There is more to happiness than money in the world, isn't there?

Miss Jackson who teaches at the Settlement House isn't rich, but she knows things. She understands people. Her eyes look straight into yours when she talks with you. She can read your mind. I'd like to see the children will be like Miss Jackson when they grow up.

44. This passage suggests that the writer______.

A. is easy to get along with

B. is never pleased with her neighbors
