The farmer looked at him and said, “ Guy, stand out in that . I’m going to release (释放) bulls（公牛）, one at a time. If you can the tail of any one of the three bulls, you can marry my daughter.”

, the young man got out and stood in the field, the first bull. The barn（牛棚） door and out came the biggest bull that he had ever seen. He that one of the next bulls had to be a better than this one, so he ran over to the side and let the bull .

A few later, the barn door opened again. Unbelievable! The young man had never seen any bull so and fierce as this one in his life. It stood there, pawing（扒） the and eyeing the young man. “What the next was like? It had to be a better choice than this one,” he thought. He did nothing but wait silently.

It was quite some time before the door opened. A came across the young man’s face. This was the weakest bull that he had ever seen. “ This one was my bull,” he to himself.

Computer technology is still developing rapidly. The computer of the future will continue to increase in value and performance while decreasing in cost. It will become smaller, but faster and more powerful.

It is possible to make some guesses about what the future of the computer will look like, based upon the types of technologies that are being developed now. A lot of progress has already been made in some of these new technologies, but some are still in their earliest stages and may not be ready for use for years. Two of the most interesting areas of computing that are currently being developed are quantum computing (量子计算) and nanotechnology (纳米技术).

Quantum computing is one possibility for the future of the computer that could make computers run far faster than even the quickest computers do today. Quantum computers could be able to do what modern supercomputers are unable to do by using transistors that are able to take on many states at the same time.

Nanotechnology could also change the face of computing, by creating computers that could be very powerful, though they are tiny in size. These computers could be incorporated (并入) into everyday objects, including electrical appliances (电器), clothes and even the human body. We will be able to use computers in new and unimaginable ways. They will become a part of our lives rather than simply being a box that is used only for specific purposes, such as work.

Quantum computing and nanotechnology will be able to play new roles, which will make us live greener lives, as well as enjoy better health and happier lives.

1.Which of the following can NOT describe the computer of the future properly?

A. Much smaller.

B. Much faster.

C. More powerful.

D. Less valuable.

2.According to the text, quantum computing _____.

A. has been put in use so far

B. can make computers run by themselves

C. can reduce the cost of computers

D. will work by using transistors

3.We can learn from the text that nanotechnology will _____.

A. create much smaller computers

B. be used in electrical appliances and clothing

C. change the structure of computers

D. make computers just serve specific purposes

4.The text is mainly about _____.

A. what nanotechnology is

B. what quantum computing is

C. what the future of the computer is

D. what future computers can bring us

Nuclear power’s danger to health, safety, and even life itself can be summed up in one word: radiation.

Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them or sense them without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.

At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.

This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated（辐射）and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its parents.

Radiation can hurt us. We must know the truth.

1.What is the main idea of the passage?

A. How radiation kills a man.

B. How to detect nuclear radiation.

C. The mystery about nuclear radiation.

D. Serious harm caused by nuclear radiation.

2. Which statement about nuclear radiation is true?

A. It is just like common radio waves.

B. It can be harmless if its level is low.

C. It can be detected by human senses.

D. It can cause cancer to human beings.

3. How can nuclear radiation kill an animal?

A. By damaging its heart.

B. By stopping it breathing.

C. By killing many cells in key organs.

D. By destroying its brain.

4. If a man is hit by nuclear radiation, he may _______.

A. die of cancer after many years B. die immediately

C. have a child who may be born weak D. all of the above

The word addiction usually makes you think of alcohol or drugs. 1. Some people are compulsive (难以自制的) shoppers. Others find it impossible to pull themselves away from their work. Still others spend countless hours watching TV or playing computer games.

2. Many people enjoy going to markets or stores more and more every day, but it’s more than a common hobby for some of them. They have turned into shopaholics. They are people who simply enjoy shopping and walking around spending money without being able to stop doing it. They are so interested in shopping that they usually buy things they don’t need. Even though they don’t have enough money, they buy everything they want.

The question is why they have this addiction. There isn’t a specific answer. Some people go shopping when they are sad, worried, upset or lonely. 3. Shopaholics say that they feel more important and better after they buy something. They also tend to have this addiction when they feel guilty.

4. Some of them can be psychological. If this is the case, people addicted to shopping should go to a support group to help them break this habit. However, the process, like for most addictions, is long, and they suffer a lot. It can also cause financial problems. They just think about satisfying their feelings, so they spend money they don’ t have. 5.

A. Once you are addicted to alcohol or drugs, it is difficult to get rid of.

B. Over the years, shopping has become a very common activity.

C. They use this activity as a way to forget their problems.

D. However, in modern-day society we are seeing some new kinds of addictions.

E. People addicted to computer games consider the games as great ways to amuse themselves.

F. They get deep in debt, and can even go bankrupt (破产) and get sent to prison.

G. Shopaholism seems to be a harmless addiction, but it can bring out problems.

Severely disabled people may soon be able to use their noses to write, drive a wheelchair or surf the Internet, thanks to a device (装置) developed by doctors in Israel.

The device will be used by breathing in and out through the nose, according to a study. Healthy people who tested the device quickly learned to play computer games and write sentences by sniffing. Encouraged by the results, the researchers decided to test their device on people who are paralyzed (瘫痪) but whose intelligence remains normal. Ten paralyzed who tested the device quickly learned to use their noses to write words, open a webpage, copy words and put them into a search engine.

With their success in helping severely disabled people to communicate * the researchers decided to make use of the new technology to design an electric wheelchair to be driven by sniffs.

Ten healthy people easily mastered sniff—driving a wheelchair through a maze (迷宫), and a 30-year-old man who had been paralyzed from the neck down for six years was as good a sniff-driver as the healthy participants at his second attempt. In other words, a paralyzed person could use the sniff controller to drive an electric wheelchair.

At the moment, sniff-controlled technology is still in the stage of development, and the Weizmann Institute has already applied for a patent on the device. "Ill be very happy if it can help us to make money, but the real problem is that I hope someone will develop it, because this would help a lot of people," said Sobel, one of the lead researchers of the study.

1. What’s the purpose of the passage?

A. To introduce a new invention.

B. To equip the disabled with life skills.

C. To show the nose's special functions.

D. To instruct doctors to apply for a patent.

2. In the test, the paralyzed people with normal intelligence can use their nose to ______.

A. type long sentences quickly

B. play computer games easily

C. enter a website without much difficulty

D. communicate with others successfully

3.With the help of the sniffing device, a 30-year-old disabled man ______.

A. spent six years learning how to drive a wheelchair

B. failed to drive through the maze at his first attempt

C. took the wheelchair controlled by healthy participants

D. managed to drive an electric wheelchair by sniffing
