In the past fifty years, American society has changed a great deal. Fifty years ago, most
Americans lived in small communities. They rarely moved from one area to another and knew their neighbors at least by name if not by close, personal relations. Life was so personal in those days that people often joked about it.They said that a person could not even stay home from church on Sunday without the whole town knowing about it. It was difficult to keep one's secret in a small community like that, but there was usually a sense of safety, of belonging, and of community togetherness in such places. Except for church and the local movie theater, there was not much entertainment. Some people dreamed about moving to the exciting life of the big cities, but most people were happy to live all their lives in the same community.

Few people experience this type of lifelong relationship or sense of community togetherness now. The American society is much more unsettled now; people often move from neighborhood to neighborhood, city to city, and coast to coast. It is rare to find people who have lived all their lives in one community. Because people move so frequently, they do not have a chance to get to know their neighbors. Perhaps this is also why Americans tend to have a more casual attitude about friendships than people from some other cultures; Americans are accustomed to leaving friends and making new friends. In such an impersonal society, people have lost the habit of saying hello to people they pass on the streets or in the hallways of their apartment buildings.

What is described in the first paragraph?

A.Entertainment in small towns.

B.Americans' adjustment to a moving society.

C.The life style. of Americans in the past.

D.Personal relations in small communities.

Why do we invest so much hope in new technology and why are we so disappointed when the Ne
xt Big Thing turns out to be just a new computer? This is what I'm asking myself after Apple's 【C1】______ over hyped product introduction. This time around the Next Big Thing is called an iPad. It's 【C2】______ an oversize iPod Touch, and it will be great for watching movies, reading books, and browsing the Web.

【C3】______ for some of us who sat in the audience watching Steve Jobs introduce the device, the whole thing felt like a 【C4】______ . The iPad is a perfectly good product. It's reasonably 【C5】______ , and after spending a few minutes with one, I'm pretty sure I'll buy one for myself and probably 【C6】______ second one for my kids to watch movies on road trips.

Then why are we so【C7】______? The case is that at the very 【C8】______ , we had hoped a tablet from Apple would do something new. Jobs and his 【C9】______ kept using words like "breakthrough" and "magical", but the iPad is 【C10】______ It might turn out to be magical for Apple, because 【C11】______ Jobs is really doing here is trying to【C12】______the personal computer with a closed appliance that runs software only from Apple's online App Store. So instead of selling you a(n) 【C13】______ and never hearing from you again, Apple gets a(n) 【C14】______ revenue stream with iPad as you keep【C15】______more apps.

Are you superstitious? No, of course not. Do you believe in magic (魔法), and luck charms

Are you superstitious? No, of course not. Do you believe in magic (魔法), and luck charms (护身符), and elves or gremlins (小精灵) ? Certainly not, but if I should greet you with the usual How's business?" You'll answer "Oh, just so-so" although your business is profiting greatly. When you are successful in some venture you might say you were just lucky. And yet, you know it was probably due to your a bility and hard work. Why? Sometimes you knock on wood because wood was once a tree and there is a primitive belief that protective gods inhabit trees and knocking on wood attracts their attention so they may be credited with your successes.

If I should sneeze, only the strongest of you could refrain(克制而不) from saying "God bless you". Why bless this unsanitary (不讲究卫生的) habit? Our ancestors believed that a sneeze opened the body to invasion by devils, and invoking (召唤) the name of God made the devils get out in a hurry. You may not realize it, but you express this same "devil invasion" when you say, "Whatever can have gotten into that child?" or "I wonder what possessed me to do that?"

Although they may no longer be believed, evidences of superstitions that have had their origins in the primitive fear of the unknown still exist in modern language and gestures.

The author ______.

A.believe that most people are superstitious

B.believe that very few people are superstitious

C.believes that there are still some evidences of superstitions in what we say and what we do

D.is superstitious

The computer is a wonderful machine. It is the most important invention since the type of
engine used in cars. Today it has the greatest effect on science, industry and business, but it is being used more in education and medicine. By the end of this century it will touch the lives of everyone, even people in distant villages. It is a revolutionary invention.

The oldest kind of computer is the abacus, used in China since the sixth century. In the seventeenth century an adding machine was invented, but the first large, modern computer was built in 1973. A few years later a computer could do 5,000 additions per second. Now the computations are so fast that they are measured in nanoseconds.

Today most computers are stored-program computers, that is, they have a memory. They are getting smaller and smaller, and computing faster and faster. Even in a large computer, the part that does the actual computing is about the size of the end of a finger.

Computers can do all kinds of work. When someone buys something in a department store, in formation about the sale goes into a computer. A scientist can talk to the computer about the rocks, and the computer answers the questions. A doctor can talk to the computer and explains what is wrong with a patient. If the doctor asks why, the computer goes through its stored information and ex plains exactly why.

When early humans began fanning, it was a revolutionary change in human life. It was hundreds of thousands of years later that people developed a writing system. In less than fifty years people have developed computers that can do most of the things humans can do. This could be a frightening development.

The oldest kind of computer, the abacus, has been used since ______.

A.600

B.700

C.800

D.500

hem to do the work for him. At lunch time he did not invite the boys to have lunch with his family. The boys had to sit by the door and have lunch on the ground. The landlord was afraid that other people would see the bad food for the boys. So with a smile on his face he said to them: “Boys, go and eat in the house. This is for your food. If you eat here by the door, the dogs will bite you.” The boys were surprised. But they said nothing and went to eat in the house. The landlord was quite pleased.

nowing what lies in the way of opportunity for promotion,happiness and security.As a result,they are employed doing jobs that afford them little or no satisfaction.Our school leavers face so much competition that they seldom care what they do as long as they can earn a livin9.Some stay long at a job and learn to like it;others quit from one to another looking for something to suit them.The young graduates who leave the university look for jobs that.offer a salary up to their expectation.Very few go out into the world knowing exactly what they want and realizing their own abilities.The reason behind all this confusion is that there never has been a proper vocational guidance in our educational institution.Nearly all grope(摸索)in the dark and their chief concern when they look for a job is to ask what salary is like.They never bother to think whether they are suited for the iob or,even more important,whether the job suits them.Having a job is more than merely providing yourseff and your dependants with daily bread and.some money for leisure and entertainment.It sets a pattern of life and,in many ways,determines social status in life,selection of friends,leisure and interest. In choosing a career you should first consider the type of work which will you"re your interest.Nothing is more pathetic than taking on a job in which you have no interest,for it will not only discourage your desire to succeed in life but also ruin your talents and ultimately make you an emotional wreck and a bitter person.

Save Money by Understanding Why You Spend It

To save money, you simply need to spend less than you earn. It is easy to say, but why is' it so difficult to do? To answer this question, you need to study the factors that keep you spending all the time.

Easy access to credit

For most people, this is the biggest reason for overspending. People can easily get a credit card, simply by filling out a short form. in a bank or jumping on their website. They can borrow money from banks to go shopping, even buy cars or houses. When you aren't physically handing someone money or a check for a purchase, you will feel you are spending free money or you aren't spending money at all. Try using cash to get your spending under control.

Misusing credit cards

A credit card is an interest free short-term loan. When used as planned, this can be a powerful financial tool. The problem is when you begin to let the balance continue from month to month. If you make a $200 purchase on your credit card and find out that at the end of the month you can't afford to repay the full amount, this is when the high interest rates on the cards really begin to hurt you. That is no way of saving money.

Giving in to temptation

We all need to enjoy life, but don't waste your financial future for a few guilty pleasures today if they aren't in your budget. When you know that you can't afford an activity, don't give in. Instead, invite your friends over for a home dinner party, game night, or some other activities where you can still enjoy time together, but without breaking your budget.

() 26. For most people, easy access to credit is the biggest reason for overspending.

() 27. Using credit card is an effective way to get your spending under control.

() 28. You have to pay for the credit card loans by the end of each month.

() 29. Using a credit card to pay is spending free money.

() 30. Always pay attention to your budget while spending.
