　　The villagers of Yaluma in Southern Mexico are some of the poorest people in the country. But now they have an extra source of income.They are being paid to grow and develop forests by the organization in charge of Formula One racing (一级方程式赛车),which pumps 5,500 tons of carbon dioxide (CO2) into the air every year.The idea is that the forests being planted around Yaluma will absorb this amount. It will also provide people there with money while wiping out motor racing's environmental debt.
　　Projects like this go under the name of "carbon trading". The basic idea is that governments and companies can buy the right to pump CO2 into the air by investing in green projrvyd. They can buy so-called "carbon credits" from countries which have succeeded in reducing CO2 emissions(排放物).
　　Supporters of carbon trading say that it brings money and green technology to poorer countries.It also provides a new way of doing busingess and spreading prosperity. They point out that the process of globalization will give people everywhere the most possible choice of products and services. Carbon trading is just another way of bringing that about. It is a "win - win" situation.
　　Opponents argue that nature comes before lifestyle. CO2 emissions need to be reduced, not bought and sold. And they believe that the rich world should lead the way.People might be willing to change the way they live to help save the world, but not to help the rich countries keep a lifestyle that depends on pollution.
　　Supporters of carbon trading believe in unlimited growth.Opponents believe that nature sets limits to the choices we make on how to live.It is "don't do " against "can do". It is life against lifestyle.
　　It is believed that modern lives are about choice.For example,the world can choose to take the danger of global warming seriously.And the sooner we choose to do it, the more choices we have about what to do next and the more time we have to do it in. We can also choose to pay no attention to the danger of global warming to keep our lifestyles. Then one day nature may give us no choice at all,and maybe not much of a life,either.
　　64.Carbon trading is discussed in the text in order to show the importance of ______ .
　　　A.reducing pollution B.taking care of forests
　　　C.spreading prosperity D.choosing lifestyle or nature
　　65."Carbon credits" may be used to ______.
　　　A.get the right to pump CO2 into the air
　　　B.get the right to pump CO2 into poor countries
　　　C.learn about the way to reduce CO2 emissions
　　　D.improve the way to reduce CO2 emissions
　　66.We can infer from the text that in the "win - win" situation _____.
　　　A.rich countries perform their duty to help poor countries
　　　B.poor countries get what they need from rich countries
　　　C.both rich countries and poor countries get what they need
　　　D.rich countries learn from poor countries in reducing pollution

No one can believe that the over 6 300-kilometer long Great Wall might disappear some day.Believe it or not,the Great Wall is being destroyed by people.Less than 20 percent of the Great Wall built in the Ming Dynasty is still perfect,but about 80 percent is in danger.The Great Wall can be called “great” mostly because of its amazing length.But we should realize that the length was made up of one brick at a time.If we do nothing to save the Great Wall,it will become a series of separate wasteland rather than a historic site.

The Great Wall is actually a series of walls built and rebuilt by different dynasties over the past 2 000 years.It began in the rule of China’s first emperor,Qin Shihuang of the Qin Dynasty (221 BC～206 BC),and lasted into the Ming Dynasty.The parts built before the Ming Dynasty have nearly disappeared.People are familiar with sections such as Badaling in Beijing and Jiayuguan Pass in Gansu because they have been open to tourists for many years.But those sections far away from the public eyes have been almost forgotten.

Few local people knew the 3-meter-high walls made of earth and stones beside them are part of the Great Wall.The lack of knowledge is considered as one of the main reasons behind human.

The bricks on the Great Wall are carried off by countryside people to build their houses,sheep corral(畜栏) and pigsties(猪圈).Some were taken away to build roads.Bricks carved with people’s names are put away as remembrance.Rubbish is spread over the battlements(城垛).The bricks can be sold for 15 yuan per tractor load.Those who destroyed and are destroying the Great Wall know its name,but are not clear about its cultural meaning.It will take a long time to let them know this.The local farmers not only carried off the body of the Wall but dug out the entire base.

It is necessary to protect the Great Wall.First of all,the officials should be aware of theimportance of the Great Wall.Young Chinese should know more about the nation’s great civilization (文明)and learn to love it.

1.The main reason for which the Great Wall can be called“great”is__________.

C.Some parts of it are being destroyed.　　　　 D.It’s too old to be used again.

3.The underlined part “those sections far away from the public eyes” refers to the parts of the Great Wall__________.

A.that are too difficult to understand　　　 B.nobody can watch

C.that are too far to been seen　　　　　　 D.that are not well known to the public
