Question

Our factories and homes burn coal and oil. Every year we have forest fires somewhere. Many scientists believe that the climate is changing.
The earth will perhaps be warmer by about 7 degrees centigrade. At the South Pole and the North Pole, the ice will melt (融化). The sea level (海平面) will rise by about 7meters. As a result, water will cover cities like London, Tokyo and New York. Some ports and towns along the coasts will disappear under water.
Some other scientists think that the dust, smoke and pollution from coal, wood and oil fires will block out the sunrays(紫外線). Then the earth will become colder and great sheets of ice will cover Europe and North America.
When chemicals in the air mix with rain, we have acid (酸) rain. Acid rain can bring us great harm. It destroys forests and kills life in lakes and rivers.
People are beginning to see how serious the problem is. They find it important to work with nature instead of against it. They are trying to save the earth in many different ways. But one of the most important things to do is to make people understand that saving the earth is saving ourselves.
小題1:Some scientists believe that          .               
A. the earth is growing warmer
B. we can find oil in our forests
C. we have to burn down the forests every year
小題2:Ice at the poles will          if the earth gets warmer.
A. cover cities like London and Tokyo
B. raise the sea level by 7 degrees
C. become water and make the sea level rise                
小題3:Acid rain          .
A. brings great changes in our climate
B. kills pests in lakes and forests
C. kills the fish in rivers and lakes                        
小題4:What can we learn from the third paragraph?
A. The dust together with pollution from coal, wood and oil fires will bring us more heat from the sun.
B. The sunrays will come more because of the dust and pollution from fires.
C. As a result of the dust and pollution from coal, wood and oil fires, the earth will become colder.                                                                  
小題5:Which statement is TRUE?
A. People have come to know the importance of working with nature.                
B. All the scientists agree that our earth is sure to become warmer and warmer.
C. The sea level will rise if the earth gets colder.

試題分析：有些科學(xué)家認(rèn)為石油，煤炭等的燃燒將會(huì)使地球變暖，導(dǎo)致兩極冰川融化，海平面上升，有的城市將被淹沒。而另一些科學(xué)家則認(rèn)為燃燒產(chǎn)生的氣體會(huì)傷害大氣層，導(dǎo)致地球變冷。不論怎樣，人類都已經(jīng)意識(shí)到問題的嚴(yán)重性，已經(jīng)知道了跟自然和諧相處的重要性。呼吁大家為我們自己的生存保護(hù)地球。
