Houston,Texas(June8,2002)---In 2004,the National Aeronautics and Space Administration(NASA)will send two robots( 機器人 )to separate places of Mars to seek out past and 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(宣布)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（宇宙飛船)will touch down on Mars,after a seven-and-a-half-month space flight,on January 2 and 20,2004.

The robots,each weighing 150kilograms can cover 100 metres per day.They are designed to be able to examine the mineral(礦物質 )content of the soil,and their special camera will take pictures of the lands and hills.Although they will be under control from 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.

I am so worried about global warming. We need stop cutting down all of the trees so that they can absorb the carbon dioxide. I think the Kyoto Protocol （京都議定書) to stop pollution is a great idea ,and I hope our country will decide to follow it, too.

                                                             — Eli S.,10,Texa

People should do all they can to help stop pollution, even if it is something as little as recycling your soda can. Every little thing helps. Maybe schools can put recycling bins in classrooms. Students can bring in all of their cans and bottles and see how many the school can collect.

                                                  — Lindsey A.,11, Massachusett

The United States should take action to help stop pollution. Since we are one of the richest countries, we should at least spend a little money to help.

                                                  — Aaron z,11,Massachusett

It is not good that the United States is not following the Kyoto Protocol. The U.S. is one of the most pollution emitting (污染物排放)countries in the world. Even if the rest of the world agrees to follow those rules, without the U. S. and its big businesses agreeing, global warming will still be a big problem.

                                                         —Augustine S.,11,Ohio

The world needs to learn more about global warming problems. If we do not do something soon then some of Earth’s coolest animals will become extinct. People should use solar power instead of things that pollute the atmosphere!

                                                    — Jillian J.,10,Pennsylvania

Global warming is very dangerous, and it must be prevented. Even if people think that it cannot be stopped ,we should  at least try. Stopping global warming is more important than keeping our businesses going. What about the penguins(企鵝)and the polar bears? We can’t just let them become extinct.

                                                        —Samantha R.,11,Illinois

Why does Lindsey suggest schools put recycling bins in classrooms?

  A. To keep the classroom clean          B. To help protect wild animals.

  C. To help protect our earth.     D. To collect waste in classroom.

Augustine worries that global warming problems will be difficult to solve because       .

  A. many people think that global warming cannot be stopped

  B. more and more trees are being cut down

  C. American government spends little money stopping pollution

  D. the U.S. refuses to follow the Kyoto Protocol

Jillian and Samantha believe that      .

  A. solar power is earth-friendly energy   

B. global warming threatens animals’ survival

C. America is the richest country in the world

D. the penguins and the polar bears are dying out

  What do the six children mainly talk about?

Tom, Mary, Jason, Ann 和Juliet想根據各自的興趣愛好挑選自己喜歡閱讀的文章。閱讀下面某雜志的文章摘要（A----F），選出適合他們閱讀的文章。選項中有一項是多余選項。

A. The Forbidden City, situated in the heart of Beijing, is the largest and the most complete imperial palace and ancient building complex in China. It was home to 24 emperors of the Ming (1368—1644) and Qing (1616—1911) dynasties. The construction of the palaces in the Forbidden City began in 1406. The project spread over 15 years and was not completed until 1470. Most of the buildings in the Forbidden City were rebuilt many times, although they maintained the original style.

B. Mount Tai, the leader of the “Five Sacred Mountains”, is located in the center of Shandong Province, spanning the ranges of Tai’an and Jinan. It covers an area of 550 square kilometers, and its main peak is about 1,532.7 meters high. Mount Tai is a natural museum with many cultural relics and artwork like Heavenly Queen Pool, Red Gate Palace and Mid-Heaven Gate. Besides historic relics, Mount Tai has unique natural scenery.

C. Each year, forecasts of when the blossoms will open are headline news. The information is used by cities to plan cherry blossom festival, travel agencies to schedule tours, and ordinary people to choose dates for parties involving lots of eating and drinking under the trees.

D. Hong Kong is perhaps the best shopping place in the world with reasonable prices, various products and best service. In Hong Kong, shopping is not only a “social activity” but also an important part of recreation and a way of life. Visitors can enjoy the shopping environment and experience the fashion trend.

E. The Leaning Tower of Pisa leans because of the unstable soil on which it was built. The construction started in 1173. The building began to lean as soon as the first three floors were completed. Nevertheless, building continued, and the seven-story structure was finished between 1360 and 1370. It leans a bit more each year, and it was closed for repairs in 1990. Engineers worked to stabilize the foundation and straighten it slightly to prevent damage.

F. Centuries ago, the African elephant inhabited most of the African continent. Today, elephants are found only in the south of the Sahara. As a result of the habitat loss, along with poaching（偷獵）, the number of elephants has greatly declined. The decline has caused serious concern about the long-term survival of the species.

以下是Tom, Mary, Jackson, Ann 和Juliet各自的興趣愛好的描述。請匹配最適合他們喜歡閱讀的文章。

1.Tom is a history teacher at Wuhan University. He has a strong desire of studying the ancient Chinese architecture.

2.Mary is a volunteer, who supports and encourages people to protect wild animals and plants.

3.Jason is a student of Houston University. He dreams of seeing Japanese cherry blossoms with his friends. After graduation, he will go on a trip to Japan.

4.Ann is an energetic girl who loves climbing mountains. She said, “Climbing a mountain is hard work, but the higher I climb, the more wonderful my view is.”

5.Juliet often buys new clothes and shoes alone or accompanied by a friend. When she feels annoyed about a matter, going shopping always makes her relaxed.
