We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.

Not long ago, my wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is bending up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emissions（排放）of carbon dioxide（CO₂）and other greenhouse gases that are trapping heat in our atmosphere. 21世纪We decided to try an experiment. For one month we recorded our personal emissions of CO₂^.. We wanted to see how much we could cut back, so we went on a strict diet. The average US household（家庭）produces about 150 pounds of CO₂a day by doing common-place things like turning on air-conditioning or driving cars. That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce? For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting（融化）of the ice sheets in Greenland or West Antarctica. “To stay below that point, we need to reduce CO₂emissions by 80 percent,” he said.

Good advice, I thought. I’d opened our bedroom windows to let in the wind. We’d gotten so used to keeping our air-conditioning going around the clock. I’d almost forgotten the windows even opened. We should not let this happen again. It’s time for us to change our habits if necessary.

Why did the author and his wife try a new diet?

A. To take special kinds of food B. To respond to climate change.

C. To lose weight D. To improve their health

The underlined words “tipping points” most probably refer to .

A. freezing points B. burning points C. melting points D. boiling points

It can be inferred from the passage that 2___. ..

A. it is necessary to keep the air-conditioning on all the time ..

B. it seems possible for every household to cut emissions of CO₂

C. the average US household produces about 3,000 pounds of CO₂a month.

D. the average European household produces about 1,000 pounds of CO₂ a month.

Which of the following would be the best title for this passage?

A. Saving Energy Starts at Home B. Changing Our Habits Begins at work

C. Changing Climate Sounds Reasonable D. Reducing Emissions of CO₂ Proves Difficult

A typical① Chinese Internet user is a young male who prefers instant messaging to e-mail, seldom makes online purchases② and favors news, music and games sites. According to a study, about two-thirds of survey participants③ use the Internet for news — often entertainment-related — or for online games. About half download music and movies.

They also tend to prefer instant messaging to e-mail, and they are depending on the Internet more frequently than before to communicate with others who have the same professions, hobbies and political interests. Online purchases still remain unpopular in China. Three-quarters of users surveyed have never bought anything over the Internet, and only 10 percent make purchases even once a month. Among those who do buy online, most pay for entertainment while others buy phone cards, or computer hardware or software.

“Many people don’t trust the quality of goods bought online,” Guo said Wednesday. “If they buy it in a store and don’t like it, they can easily bring it back.”

The survey was done in five major cities: Beijing, Shanghai, Guangzhou, Chengdu and Changsha. Results do not necessarily project countrywide because Internet use in rural areas is lower than in cities. Guo describes the typical netizen④ in the five cities surveyed as young, male, richer and more highly educated. Males make up two-thirds of the Internet community, and more than 80 percent of users are under 24. Among people ages 25 to 29, 60 percent to 80 percent go online.

China has more than 100 million people online, second in the world to the United States.

Notes:

① typical adj. 典型的

② purchase n. / v. 购买

③ participant n. 参与者

④ netizen n. 网民

No one can believe that the over 6,300-kilometer 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 (221BC----206BC), 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 parts 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 corrals and pigsties. Some were taken away to build roads. Bricks carved with people’s names are put away as remembrances. The rubbish is spread over the battlements. The brick can be sold 15 yuan per tractor load. Those who destroyed and are destroying the 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 also dug out the entire base.
It is necessary to protect the Great Wall. First of all, the officials should be aware of the importance of the Great Wall. Young Chinese should know more about the nation’s great civilization and learn to love it.
