   Houston, Texas (June 8. 2002)–in 2004, the National Aeronautics and Space Administration (NASA) will send two robots to separate places of Mars to seek out past or present signs of water. It is an exciting idea to send two robots driving over very different places of Mars at the same time, to be able to see what is on the other side of the hill.

   Last month, NASA announced it was sending one robot to Mars, but after two weeks, it decided there was enough money for two. The robots will be sent up within two weeks of each other in May and June of 2003 from Kennedy Space Center. If all goes well, the two spacecraft will touch down on Mars, after a seven-and –a-half-month space flight, on January 2 and 20, 2004.

   The robots, each weighing 150 kilograms, can cover 100 meters per day. They are designed to be able to examine the mineral content of the soil, and their special camera will take pictures of the lands and hills. Although they will be under control from the earth, the robots are able to move more freely compared to those sent up before them.

   The actual landing points have not been determined yet, but the scientists say it will be in areas where they hope to find water.

1.According to the news report, scientists plan to send robots up to Mars to _____.

A.find out whether there is water on Mars   B.see if robots can find minerals there  

C.test how fast robots can drive there                 D.prove that robots can work on Mars

2.How long in between will the two robots be sent to Mars?

A.1 year        B. 7.5 months                   C. 2 months       D. 2 weeks

3. One of the important jobs for the robots on Mars is to _______.

  A.study the soil                                      B. walk everywhere

  C.test the new camera                                 D. find a suitable landing point

4. We can infer from the last sentence that scientists ________.

   A. have changed the landing points many times 

B. hope to land the robots on the surface of water

   C. are still working on the plan

The world’s population continues to grow. There are about five billion of us on earth now. It could reach six billion in 10 years’ time, and eleven billion in another 75 years. Experts have long been concerned about such growth. Where will we find the food, water, jobs, houses, schools and health care for all these people?

A major new study shows that situation may be changing. A large and rapid drop in the world’s birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. This is happening in both developing and industrial nations. Scientists said they found a number of reasons for this. More men and women are waiting longer to get married. More women are going to school or working at jobs away from their home instead of having children. And more governments, especially in developing nations, now support family planning programs to reduce population growth.

China is one of the nations that have made great progress in reducing its population growth by about one half since 1970. China now urges each family to have no more than one child. And it hopes to reach zero population growth before long, that is, the number of birth equaling the number of death.

Several nations in Europe already have fewer births than deaths. Experts said that these nations could face a serious shortage of workers in the future.

1. In the sentence “Experts have long been concerned about such growth”, the phrase “concerned about” is similar in meaning to_____.

A. worried about      B. related to       C. busy working on     D. made a study of

2. “Family planning programs” means______.

A. economic policy in a country         B. economic policy in a family

C. TV programs for a family            D. birth control in a country

3. The world’s birth rate has dropped because_____.

A. people marry at a much later time

B. women would rather go to study or work than have children

C. some countries are carrying out the family planning programs

D. all the above

4. We hope that soon the number of birth and the number of death in China will_____.

A. be greatly different          B. be equal to each other
