It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is actually worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect" - holding in heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.

Another view, less widely held, is that increasing particulate (废气排往空中而形成的微粒、颗粒) matter in the atmosphere is blocking sunlight and lowering the earth's temperature ─ a result that would be equally disastrous. A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will offset each other and the world's temperature will stay about the same as it is now.

As pointed out at the beginning of the passage, people used to think that air pollution ______.

    A. caused widespread damage in the countryside

    B. affected the entire eastern half of the United States

    C. had damaging effects on health

    D. existed merely in urban and industrial areas

As far as the greenhouse effect is concerned, the author ______.

    A. shares the same view with the scientists

    B. is uncertain of its occurrence

    C. rejects it as being ungrounded

    D. thinks that it will destroy the world soon

The underlined word “offset" in Para. 2 could best be replaced by______.

    A. slip into    B. make up for  C. set up   D. catch up with

This passage is mainly concerned with ______.

    A. the greenhouse effect                B. the burning of fossil fuels

    C. the potential effect of air pollution    D. the possibility of a new ice age

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 （京都议定书) 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(企鹅)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?

     A. Environmental problems.         B. The Kyoto Protocol.

     C. Animal protection.              D. The climate change.

NASA is moving ahead with plans to put a long-armed lander on Mars’ icy north pole to search for clues^① for water and possible signs of life.

The $386 million Phoenix Mars is planned to touch down in the Martian arctic in 2008. The stationary probe will use its robotic arm to dig into the icy land and pick up soil samples^② to analyze. In 2002, the Mars Odyssey orbiter spotted evidence of ice-rich soil near the arctic surface.

Scientists hope the Phoenix mission will find clues to the geologic history of water on the Red Planet and determine whether microbes^③ existed in the ice.

Phoenix will be the first mission of the Mars Scout program, a renewed, low-cost effort to study the Red Planet. “The Phoenix mission explores new territory in the northern plains of Mars analogous to the permafrost regions on Earth,” Peter Smith said.

True to its name, Phoenix rose from the ashes of previous^④ missions. The lander for Phoenix was built to fly as part of the 2001 Mars Surveyor program. But the program broke down after the well-known disappearance of the Mars Polar Lander in 1999. The Polar Lander lost contact during a landing attempt near the planet’s south pole after its rocket engine shut off prematurely, causing the spacecraft to fall about 130 feet to almost certain destruction.

The Phoenix probe had been in storage at a Lockheed Martin clean room in Denver before it was reused for its present mission. It will carry science instruments that were designed for the Mars Surveyor program including an improved panoramic camera and a trench-digging robotic arm. Phoenix will lift off from the Kennedy Space Center in August 2007 and land on the planet nine months later.

Notes:

clue  n. 线索

sample  n. 标本，样品

microbe  n. 微生物

previous  adj. 先前的

        C. take photos and send them to the earth

        D. find the remains of the Mars Polar Lander

There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect”— conserving heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.

Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature — a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people neglect the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile?
