Global warming is the process of earth's atmosphere heating up. Over the last 100 years, the average temperature of earth's atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth, s climate.

Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment are some of the that the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.

The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, prevent heat energy from escaping back into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.

Today, most scientists are pretty sure that the rising temperature can,, t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.

The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.

Over the past last 100 years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.

1.What is mainly talked about in this passage?

A.The melting of glaciers. B.Global warming.

C.The world's weather. D.The earth's temperature.

2.What causes global warming according to scientists?

A.Human activities B.The nature itself

C.The earth's atmosphere D.New discoveries

3.From passage we can see that global warming will bring about________.

A.the pollution in the atmosphere. B.the rise of glaciers.

C.noisy pollution. D.natural disasters.

Global warming happens when greenhouse gases trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows，but it can’t get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can’t get out. As a result，the temperature rises.

Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on. Without it，the earth would be freezing，or it would be burning hot. It would be freezing at night because we would not get the sun’s heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter(过滤)it，so people，plants，and animals would be exposed to all the light and heat.

Although the greenhouse effect makes the earth able to have people living on it，if there gets to be too many gases，the each can get unusually warmer, and many plants，animals．and people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat,and it would also limit the food that animals have. With less food for the animals that we need to survive we would even have less food. Gradually,people，plants，and animals would all die of hunger．

People are doing many things to try to stop global warming .One thing is carpooling—driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now,more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming,kids call do just as much.

1. By the example given in Paragraph l, the author wants to__________.

A. explain how global warming happens.

B. show his feeling in a car in hot summer.

C. tell us cars are causes of greenhouse gases.

D. say that I there are greenhouse gases in every car.

2. The underlined word‘it” in Paragraph 2 refers to__________.

A. light　　 B. greenhouse effect

C. temperature　　 D. heat

3. What is the effect of atmosphere?

A. It only traps the heat of the sun.

B. It does great harm to humans.

C. It makes the earth neither too hot nor too cold.

D. It prevents all the light from the sun shining on the earth.

4. What is the main idea of the third paragraph?

A. lf there is greenhouse effect,all the plants will die

B. Human beings are likely to disappear from the earth

C. Crops can ′t take in the heat lf there is greenhouse effect

D. Although greenhouse effect is necessary,too much of it will cause us to die.

5. What will the author most probably discuss in the paragraph that follows?

A. What kids can do to help stop global warming.

B. Who should be responsible for the environmental problems.

C. What global warming is doing to the environment.

D. Why cars and buses pollute the air a lot.

Global warming is the increase of the earth’s average surface temperature due to the effect of greenhouse gases, for example, carbon dioxide, which trap heat that would otherwise escape from the earth. After the trees are cut down and more greenhouse gases are released, the “blanket” around the earth called the ozone layer (臭氧层), will get thicker. This catches more heat and makes the earth hotter. Luckily, there are many things that every citizen of the earth can do to help reduce the effects of global warming, and it’s never too late or too early for children to take action.

The children should learn what a carbon footprint is. A carbon footprint is the amount of carbon and greenhouse gases people make as they lead the daily life and go about the normal activities. In other words, the carbon footprint is a measure of the environmental impact (冲击) the life has. To live an environmentally friendly life that doesn’t contribute to global warming, people want to have the smallest carbon footprint possible.

Almost everything people do contributes to global warming and is related to fossil fuel consumption. These can be direct uses of fossil fuels, like riding in a gasoline-powered car, or indicrect contributions to greenhouse gases, such as eating fruits or vegetables that had to be shipped from far way to reach their tables.

If a child wants to make a contribution to reducing global warming, he should ride a bicycle to the near park, school, his friend’s house, or anywhere else instead of taking the car. Or he may try to walk or jog, which is also helpful. In addition, although trains and buses often run on fossil fuels, on average, each person uses less energy and produces less pollution to run. Next time if children with their parents have to get around town or it’s too far to walk or bike, take the bus or other public transportation instead of asking for a ride.

1.What is the first paragraph mainly about?

A.A brief description of carbon footprint

B.The serious water pollution.

C.The protection of ozone layer.

D.The causes of global warming

2.Which of the following can describe the carbon footprint?

A.Useless. B.Expensive.

C.Helpful. D.Attractive.

3.What can kids do if they want to help reduce global warming?

A.Go to the near park by bus.

B.Walk or cycle as much as possible.

C.Keep staying at home or school.

D.Go around the town with parents by car.

4.What can be a suitable title for the text?

A.What Can People Do to Use Less Energy?

B.How Can Kids Help Reduce Global Warming?

C.How Does Carbon Footprints Measure Pollution?

D.Why Global Warming Affects Humans’ Life?
