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

Will there always be 31 water? When you consider how necessary water is to each and every one of us and to all 32 (live) things, and when you observe how man has mismanaged other 33 (nature) resources, you may have reason to worry. Man has badly polluted his sources of water 34 Earth. And he uses more and more water each day. Can man learn to treat 35 (pollute) water for reuse fast enough 36 (keep) pace with the world’s technology and 37 (grow) population?

At the present time there is no serious shortage of water in the United States. Water, however, is not 38 able to meet all the local needs. Some areas, such as the southwestern part of our country, get less rain than 39 . In these areas, water must be brought in from 40 outside. Los Angeles, for example, must obtain its water from sources hundreds of miles away in the Colorado River and the rivers of northern California.

The Zhoukoudian Beijing Man Site is one of the most important world heritage sites in China．Since the discovery, which changed China’s knowledge of its history, was made in the 1920s, Zhoukoudian has become an important place for archaeologists from all over the world．At the site in the south-west suburb of Beijing, there is, for example, the earliest evidence of the use of fire by humans．It has also been proved that people lived there continuously between 500,000 and 10,000 years ago．

Today, however, Zhoukoudian is in serious danger．Parts of the cave have been badly affected by rain and exposure to the air．Some areas are almost completely covered in weeds, causing serious damage．Pollution from nearby cement factories has also contributed to the problem．

The site is extremely expensive to maintain and it will cost between three and five million yuan to repair it．At the moment, visitors are not allowed to visit the caves．[来源:]

Zhoukoudian is on the World Cultural Heritage List, organized by UNESCO, the United Nations Educational, Scientific and Cultural Organization．The list is constantly checked．Any site which is seriously damaged or which is not properly protected is an endangered heritage, and UNESCO is very quick to do something about situations like this．They have recommended that the site be closed and repaired．If nothing is done to repair it, it could be removed from the list．

This is a very serious matter and the Chinese Academy of Sciences is trying to raise public awareness about it．They have suggested that the general public be encouraged to help with the problem．A professor at the Academy has proposed that a fund be established to raise money．

Dr Zhu Ming of the Academy said, “ We have requested that the government get involved, but we also need assistance from ordinary people．They can help by contributing to the cost of repairing the caves．They are a precious part of our cultural heritage—it is of vital importance that we do something．If not, it will be a catastrophe．”

A．Because the site tells some information about how man lived in the old times．

B．Because it has brought in lots of money as a place of interest．[来源:学&科&网]
