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 CO2 a 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 CO2 emissions 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?

There are some places in the world where great cities once stood. There were trees, gardens and grass. But now these cities have gone and the places are like deserts. Scientists began to study this land to find out what happened. Many of them believed the land died when the trees were cut down.
Trees help other plants grow and help hold the soil in place. They keep the soil from blowing away. The leaves of trees on the ground keep rainwater from running off. Trees near farms protect growing plants from strong winds.
Once there were hundreds of farms in the southwestern United States. Then the farms turned into fields of dry dust. Trees might have saved these farms. But few trees grow in the dry southwest now.
Now we try to save trees. In many places, when a tree is cut down , a new tree is planted in its place . We do not want the land to die.Places where great cities once stood are now like ______ .

Scientists in Canada say big ocean fish have almost disappeared from the world since the start of industrial fishing in the nineteen-fifties. The scientists found that population of large fish like tuna; swordfish and cod have dropped by ninety percent in the past fifty years.
The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazine Nature published the findings.
The scientists say the common method called longline fishing is especially damaging to populations of large fish. This method involves many fishing lines connected to one boat. These wires can be close to one-hundred kilometers long. They hold thousands of sharp metal hooks to catch fish.
Longline fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one-hundred hooks. The study says longline fishing boats now might catch one fish per hundred hooks.
The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests that whole populations can disappear almost completely from new fishing areas within ten to fifteen years.
Ransom Myers of Dalhousie University in Nova Scotia led the study with Boris Worm of Dalhousie and the University of Kiel in Germany. Mister Worm says the destruction could lead to a complete re-organization of ocean life systems. Mister Meyers says the decreased number of large fish is not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors(祖先). He says not only are there fewer big fish, they are smaller than those of the past.
American government scientists say even with the best efforts to protect fish populations, decreases are to be expected.Where is the passage probably taken from?
A.A story book. |
B.A business magazine. |

In white shirt, blue pants, black cloth shoes and two pigtails, Jingqiu gives off an air of great "pure beauty" in Zhang Yimou’s new movie Under the Hawthorn Tree, which tells the story of the sad romance of Jingqiu and a handsome young man named Laosan set at the end of the "cultural revolution" (1966-- 1976).
Before it was released, moviegoers foresaw what this "pure beauty" could be. Director Zhang complained of how long it had taken him to find the right girl for the part of Jingqiu -- a character so innocent. She believes that simply lying on the same bed as a man will make her pregnant.
It was 18-year-old Zhou Dongyu who stood out from the crowd. According to Zhang, Zhou has "eyes that are clear like a fountain on a mountainside". Born to an ordinary worker's family, the Shijiazhuang girl was in her final year of high school and working hard for a place in an art college.
"If you have fair skin and clear eyes, as Jingqiu does, it is easy to look pure. Girls today wear so many jewels and make-up--that's the reason Zhang was not interested," said Du Yanlai, 17, of Chengdu.
While some teenagers consider such "pure" beauty illusory, others believe that it speaks of something soulful.
Purity is all about an innocence that shines through from within, thinks 16-year-old Tan Mengxi of Nanjing. "Being pure can be simple, not having complicated thoughts and being inexperienced. However, it doesn't mean an ignorant or native person. So, a person is pure in his or her nature if he or she is always enthusiastic and able to deal with difficult matters independently. This purity doesn't pass with time, "she said.What's the real purity according to Tan Mengxi?
A.Having eyes as clear as a fountain. |
B.Not wearing so many jewels and make-up. |
C.Being ignorant and native. |
D.Being simple, enthusiastic and able to manage things alone. |
What does the underlined word “illusory” mean here?
A.unreal. | B.unhealthy. | C.unscientific. | D.negative. |
What can we infer from the passage?
A.Zhou Dongyu, who was 18,was from an art college. |
B.Director Zhang disliked those girls with so many accessories and make-up. |
C.Different people have different opinions about purity. |
D.Many young girls in China are eager to stand out. |
The main idea of the passage is ______.
A.Why Director Zhang selected Miss Zhou as the leading star |
B.How people like the movie Under the Hawthorn Tree |
C.What makes a pure girl |
D.Why Chinese girls want to be pure |
