Global warming may or may not be the great environmental crisis of the 21st century, but — regardless of whether it is or isn’t — we won’t do much about it. We will argue over it and may even, as a nation, make some fairly solemn-sounding commitments(承诺) to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed.

Al Gore calls global warming an “inconvenient truth,” as if merely recognizing it could put us a path to a solution. But the real truth is that we don’t know enough to relieve global warming, and — without major technological breakthroughs — we can’t do much about it.

From 2003 to 2050, the world’s population is projected to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions(排放) (mainly, CO2) will be 42% higher in 2050. But that’s too low, because societies that grow richer use more energy. We need economic growth unless we condemn the world’s poor to their present poverty and freeze everyone else’s living standards. With modest growth, energy use and greenhouse emissions more than double by 2050.

No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they’re “doing something.” Consider the Kyoto Protocol(京都议定书). It allowed countries that joined to punish those that didn’t. But it hasn’t reduced CO2 emissions (up about 25% since 1990), and many signatories(签字国) didn’t adopt tough enough policies to hit their 2008-2012 targets.

The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking our dependence on fossil fuels or dealing with it.

The trouble with the global warming debate is that it has become a moral problem when it’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering problem, we’re helpless.

46. What is said about global warming in the first paragraph?

A. It may not prove an environmental crisis at all.

B. It is an issue requiring worldwide commitments.

C. Serious steps have been taken to avoid or stop it.

D. Very little will be done to bring it under control.

47. According to the author’s understanding, what is Al Gore’s view on global warming?

A. It is a reality both people and politicians are unaware of.

B. It is a phenomenon that causes us many inconveniences.

C. It is a problem that can be solved once it is recognized.

D. It is an area we actually have little knowledge about.

48. Greenhouse emissions will more than double by 2050 because of ________.

A. economic growth                       

B. wasteful use of energy

C. the widening gap between the rich and poor  

D. the rapid advances of science and technology

49. The author believes that, since the signing of the Kyoto Protocol, ________.

A. politicians have started to do something to better the situation

B. few nations have adopted real tough measures to limit energy use

C. reductions in energy consumption (消耗) have greatly cut back global warming

D. international cooperation has contributed to solving environmental problems

50. What is the message the author intends to convey?

A. Global warming is more of a moral issue than a practical one.

B. The ultimate solution to global warming lies in new technology.

C. The debate over global warming will lead to technological breakthroughs.

D. People have to give up certain material comforts to stop global warming.

There are many things we can do in our daily life to reduce the amount of greenhouse gas sent out. Probably the most important is to share what you have learned with your family and friends.

   ★ Use the family car less. Walk or cycle whenever possible. Take a bus. Try ride sharing.

   ★ Use less energy in the house by turning down the heat when you are away or sleeping and turning off lights and electrical equipment you aren't using.

   ★ If your family needs a car, make sure to buy a fuel-efficient one.  An average car sends out nearly 60 tons of carbon dioxide during its lifetime, compared to between 22 and 30 tons from a fuel-efficient car.

   ★ Encourage your family to use the car more efficiently (有效地): for example, check the air in the tires. Underinflated tires can increase fuel use by 8%. Turn the car off instead of letting it run when it is stopped. Idling uses more gas and sets free carbon dioxide into the air,

   ★ Reuse, recycle and compost (把…合成肥料 ) your waste. It takes much less energy to reuse or recycle a product than to make a new one. Correctly composting your food and yard waste removes the methane (沼气) that they would cause at the landfill site. Buying less is al- ways the best.

★ Plant trees. Trees take in carbon dioxide, reduce pollution, provide shade, and look great.

1. Which of the following does the writer suggest that we should not do?

  A. Share cars with other people if possible.  B. Make sure our car tires are well inflated.

  C. Compost our home waste at the landfill site. D. Buy less products even if we can afford.

2. A fuel-efficient car gives of ?_____ tons of carbon dioxide during its lifetime less than an average car.

A. 22-30     B. 30-38     C. 60     D. 8-30

3. The purpose of this text is to call on people ________

  A. to control greenhouse gas     B. to make full use of energy

  C. to plant more trees        D. to buy fuel-efficient cars
