Chinese team first lands on Antarctic icecap peak (南极冰盖最高点) A 12-man Chinese team landed on the Antarctic icecap peak on January 18. They are the first people to reach the peak of Dome A (海穹A). It is 4,039 meters above sea level (海拔). The team built a station there to study the changes of the weather, get ice samples (标本) from 150 meters to 200 meters below, and do other studies. So far, the team has got nearly 100-meter long ice samples from a place about 300 meters under the icecap peak. It is the first time that people have been able to get samples from the icecap peak in Antarctica and it is very important for people to study the weather changes and environmental changes in this area(地区). The Chinese scientists have also built a weather study system (系统) at the peak. The system can send out information about temperature, how strong the wind is, and many other things about the weather. The Antarctic icecap makes up (组成) 70% of the earth"s freshwater (淡水). By studying Dome A, scientists can get the lowest temperature of the earth and other information about the world"s weather changes. We can"t get this information from other places on the earth because Dome A is the best place for this kind of studies. So it is very important to land on the peak of Dome A. |
1. How many Chinese first landed on the Antarctic icecap peak? |
A. 18 B. 12 C. 150 D. 200 |
2. The team has got about 100-meter long ice samples __________. |
A. from 150 meters to 200 meters below B. from a place about 300 meters below C. from 200 meters to 250 meters below D. from a place about 150 meters below |
3. They built a weather study system to get __________. |
A. the earth"s freshwater B. ice samples from the peak C. information about the weather D. the news about other countries |
4. From this passage, we can infer (推断): After the Chinese team landed on the Antarctic icecap peak, __________ |
A. we can go there for holidays. B. the world"s weather must be better and better. C. the peak will be the best place for people to live in. D. our country will do better in the world"s weather research. |

A US doctor has planted under his skin a computer chip (芯片)that can send personal information to a scanner (扫描仪). It"s a technology that may someday be widely used as a way to identify (识别) people. The chip gives off information which will be scanned by a hand-held reader. The chip is similar to that planted in more than 1 million dogs, cats and other pets in recent years to track (跟踪) and identify them. The doctor decided to test the chip himself after the World Trade Center disaster (灾难). The dead could have been identified if their names and other important information had been chipped. Officials of the company said they hope to sell the chips to patients with man-made arms or legs or other body parts. The idea is that the chip will provide immediate and correct medical information when it is needed. The information can contain (包括) name, telephone number and other information. Or it can send out a message that, when connected to a computer, can call up records. The scanner can read it through clothes from over a meter away. The new product also could be used to control prisoners. Workplaces of great importance may want to use the chips for employees, too. Some parents may consider planting chips in young children or elderly relatives who may be unable to say their names, addresses or telephone numbers. Some medical and technology specialists (专家) said the product raises new questions about the relationship between humans and computer technology and could cause problems if it is used against some one"s wishes, or if your personal information is read by those who should not see it. 1. According to the passage, computer chips have already been used to _____. A. catch escaped prisoners B. find missing children C. follow lost animals D. treat sick people 2. The doctor decided to test the chips himself because he believed that _____. A. nobody would dare to try it B. they can be used for identification purposes (目的) C. it has been proved successful on animals D. his patients expected him to experience it first 3. Which of the following statements is best supported by the text? A. This chip has been proved to be very successful. B. The use of this chip will be favored by everybody. C. There will be a great market for chip planting in humans. D. Doctors will make good money by using chips. 4. What problem may be caused by planting chips in the human body? A. People will be controlled by computers. B. Computers could send out wrong information. C. Chips can be the cause of diseases. D. Information may be used improperly.

Governments use it to learn where people live and work and to plan what to do with the land. It is now easier than ever to use geography because of a science called space technology. The United States launched its first satellite in 1958. Some space missions (使命) that followed were geographical studies. In fact, earth science is a big part of the work of the National Aeronautics and Space Administration(NASA). Astronauts looked out of the space shuttle (航天飞机). They decided to take photographs of Earth from their vantage point. Over the years, picture quality improved. Shuttle photography now shows land features, such as rivers. It can even show the streets of large cities. Photos of the same places at different times show how the land is changing. NASA does not use just photographs, though. In 1958 it launched TIROS (the Television Infrared Observation Satellite). This first use of a satellite to study Earth was effective (有效的) in giving weather forecasts. It led to the creation of new space tools to use in geography. The Landsat Program began in 1972. This satellite sent detailed (细致的) views of Earth from space. The pictures were so precise (精确) that scientists could count the number and kinds of crops in a field. Landsat showed where Earth"s surface had faults along which earthquakes might happen. This information helped in the planning of new cities and factories. Landsat also made discoveries. In Antarctica it located ranges of unknown mountains. It pinpointed small lakes. in Virginia that were not on maps. Landsat, now more advanced, still flies today. Another space tool is Earth Observing-1(EO-1). This spacecraft flies right behind Landsat. It takes pictures of the same sites. The two sets of pictures, viewed together, show how cities grow and how other places, such as rain forests, become smaller over time. This helps scientists learn how people affect (影 响) geography. One of the newest space tools is the Geographical Information Systems(GIS). GIS is computer software that helps scientists to study Earth. GIS is different from earlier space tools. Businesses, schools, and even average people--not just the government--can use it to show them how changes in the planet might affect them. 1. Why do governments study geography according to the passage? A. To improve the environment. B. To make the land use plan. C. To make new discoveries. D. To count the crops in a field. 2. Which of the following is TRUE according to the passage? A. The U.S. satellite program began in 1972. B. Landsat was able to take pictures of other planets. C. TIROS was successful in giving weather forecasts. D. GIS can only be used by the government. 3. EO-1 takes photographs of the same places as Landsat because _____. A. the two groups of pictures can show the changes of Earth B. EO-1 is practicing for future photography missions C. Landsat is out of date and new pictures are needed D. Landsat can"t send detailed views of Earth from space 4. From the passage, we can infer that _____. A. GIS is the newest computer to study Earth B. NASA only depends on photos to study Earth C. satellite pictures can give more detailed information D. recent U. S. satellites are as advanced as the old ones | 阅读与表达。 Eating in space is different from eating on Earth. The food that astronauts carry with them does not look like the food you eat. Some food is carried in closed bags. It is cooked and frozen (冷冻) before the astronauts get it. All the water is removed from the food. In the spaceship, the astronaut puts the water back. He "shoots" hot or cold water into the food bag with a special gun. He eats the food through a small hole in the bag. Other foods come in bite sizes. The astronaut puts a whole piece in his mouth at once. There can be no crumbs (碎屑). Crumbs would float (漂浮) around the spaceship and get in the way. Meat and cake often come in bite-size pieces. Astronauts cannot drink water from open cups. The water would float in drops in the air. The water is put in the special gun. The astronaut shoots the water into his mouth. Eating in space is not easy. Astronauts must learn to eat in their way. 1. What is the food carried in closed bags by astronauts like? ___________________________________________________________________. 2. How do the astronauts eat food in space? ___________________________________________________________________. 3. How do the astronauts drink water in space? ___________________________________________________________________. 4. Why can"t the astronauts drink water from open cups? ___________________________________________________________________. 5. What is the main idea of the passage? _______________________________________________________________.
