The majority of astronauts from America have been men. At the start of the space program there was strong resistance from some people against having women in space. However, some women were very keen to become astronauts and in the end they were successful. In 1978, NASA began the first training program for women astronauts.
Judy Resnick and Christa McAuliffe were both astronauts and they were both women, but in many other ways they were very different. Both of them were on Flight STS-5L-L. Judy Resnick was born in 1949 and studied engineering at university and went on to obtain a PhD in 1977. She was a member of the first group of women selected for astronaut training in 1978, and in 1984, she became the second woman in space. During that flight, she helped to launch three new satellites and she carried out a program of research. She was, in many ways, a professional astronaut whose whole life was devoted to space travel.
Christa McAuliffe was born in 1948 and she was an astronaut almost by accident. In 1984, NASA decided to find a teacher who could accompany astronauts into space. They hoped that she would be able to communicate with students from space and encourage every one of them to be interested in space travel. Christa was a secondary teacher in history and social studies. She was a gifted teacher and she was selected from over 11,000 applicants to go on flight STS-51-L. She was also a very good communicator and she immediately established a very good relationship with the news media(radio, television and newspapers）. It was partly because of this that there was a great deal of interest and excitement about the flight. Thousands of students in schools and universities all around the country were looking forward to communicating with Christa in space. Millions of people were watching her flight with great interest. It is partly because of the excitement over McAuliffe's place in the flight that the disaster in 1986 had such an effect on people.We can learn from the first two paragraphs that ___________.
| A．Judy was against the idea of having women in space at first |

Nuclear radiation （核辐射）has a certain mystery, partly because it cannot be detected （探测）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 at once by killing plenty of cells in important organs(器官). 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 when they are killed at once. 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 reproduce themselves in an unusual way. 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 knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents.According to the passage, the danger of nuclear power lies in.
| A．nuclear mystery | B．radiation detection |
| C．radiation level | D．nuclear radiation |
Radiation can lead to serious trouble even at the lowest level.
| A．when it kills a few cells |
| B．because the killed cells can’t be replaced |
| C．if it damages a few cells |
| D．unless the damaged cells can reproduce themselves |
What does the author want to tell us?
| A．Radiation can hurt us. | B．Radiation is a subject scientists work on. |
| C．Radiation is a mystery. | D．Radiation is the source of cancer. |
Most young people enjoy some form of physical activity. It may be walking, cycling, or swimming, or in winter, skating or skiing. It may be games of football, hockey, golf, or tennis. It may be mountaineering.
Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks on high mountains? This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their relaxation.
Mountaineering is a sport and not a game. There are no man-made rules, as there are for such games as golf and football. There are, of course, rules of a different kind which it would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.
If we compare mountaineering and other more familiar sports, we might think that one big difference is that mountaineering is not a “team game”. We should be mistaken in this. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.
The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical qualities.
A mountain climber continues to improve in skill year after year. A skier (滑雪者) is probably past his best by the age of thirty, and most international tennis champions are in their early twenties. But it is not unusual for a man of fifty or sixty to climb the highest mountains in Alps. They may take more time than younger men, but they probably climb with more skill and less waste of effort, and they certainly experience equal enjoyment. The main difference between a sport and a game lies in .
| A．activity | B．uniform | C．rules | D．skills |
Mountaineering can be called a team sport because .
| A．mountaineers depend on each other while climbing |
| B．teams compete against each other |
| C．it is an Olympic event |
| D．there are five climbers on each team |
Which of the following might be the best title?
| A．How to Climb High Mountains | B．Mountain Climbers |
| C．Challenging Sports Activities | D．Mountaineering |
A well-known manufacturer of weighing machines produced a new model.
The machine had a computer inside it, and this computer could do wonderful things: it could weigh people very accurately; it could tell them their weight in their own language; and it could tell them what they should eat to reduce their weight.
The manufacturer decided to try out his machine before he sold it to the shops.
He looked around for a good place to put it and finally decided on an airport. There were always people at an airport from many different countries.

“Good morning, madam,” it said in perfect Italian. “Your weight is 72 kilos, three more than it should be for a woman of your height, age and nationality. This is because you have been eating too much spaghetti. I suggest you eat more fruit and vegetables. Please have a nice day”.
The second person to use the machine was a Chinese girl. She stood on the machine, put a coin in and waited to hear her weight.
“Good morning, Miss," the machine said in perfect Chinese. "Your weight is 38 kilos, exactly the correct weight for your height, age and nationality. Continue to eat what you are eating. Please have a nice day.”
The third person to use the machine was a huge Australian woman. She walked up to the machine and looked at it for a long time.
