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?
| 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 CO2 a 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 |
Industrial pollution is not only a problem for the countries of Europe and North America but also an extremely serious problem in some developing countries. For these countries, economic growth is a very important aim. They want to introduce industries, and so they put few controls on the industries which cause pollution.
Cubatao, an industrial town of 85 000 people in Brazil, is an example of the connection between industrial development and pollution. In 1954, Cubatao had no industry. Today it has more than twenty large factories, which produce many pollutants(污染物). The people of the town are suffering from the poisonous matter in their environment and the bad effects can be clearly seen. Birth shortcomings are extremely common. Among children and adults, lung problems are sometimes twelve times more common in Cubatao than in other places.
It is true that Brazil, like many other countries, has laws against pollution, but these laws are not enforced strictly enough. It is cheaper for companies to take no notice of the laws and pay the fines(罚款) than to buy the expensive equipment that will reduce the pollution. It is clear, therefore, that economic growth is more important to the government than to the health of the workers. However, the responsibility(责任) does not completely lie with the Brazilian government. The example of Cubatao shows that international companies are not acting in a responsible way either. A number of the factories in the town are owned by large companies from France, Italy, and the U. S. They are doing things in Brazil that they would not be able to do at home. If they caused the same amount of pollution at home, they would be severely(严厉地) punished or even put out of business. Why don’t developing countries have strict pollution controls?
| A．The new industries they want to introduce do not cause much pollution. |
| B．Pollution is not a serious problem for developing countries. |
| C．They don’t realize the balance of nature will be destroyed by some pollutants. |
| D．If they put stricter controls on industry, fewer companies would build new plants in developing countries. |
What is the author’s purpose in taking Cubatao as an example?
| A．To show that industry can develop very fast in developing countries. |
| B．To show that the pollution problem in Brazil is extremely serious. |
| C．To show that industrial growth can cause pollution problems for developing countries. |
| D．To show that pollution is killing many people and destroying the whole economy of Brazil. |
How is the health of the population of Cubatao?
| A．There are more heart diseases among people who live near chemical factories. |
| B．More people suffer from lung diseases because of poisonous matter. |
| C．Their health is affected by pollutants the same way as that of other Brazilians. |
| D．Babies there are found not as bright as those who live in other places. |
Why do some foreign companies like to set up their plants in Brazil?
| A．The investment(投资) environment in Brazil is suitable for them. |
| B．They will not be severely punished if they cause pollution in Brazil. |
| C．They can make much money because they do not have to pay Brazilian workers much. |
| D．They can act in an irresponsible(不负责任的) way in Brazil because there are no pollution laws there. |
“Congratulations, Mr. Jones, it’s a girl.”
Fatherhood is going to have a different meaning and bring forth a different answer from every man who hears these words. Some feel proud when they receive the news, while others worry, wondering whether they will be good fathers. Although there are some men who like children and may have had considerable experience with them, others do not particularly care for children and spend little time with them. Many fathers and mothers have been planning and looking forward to children for some time. For other couples, pregnancy(怀孕) was an accident that both husband and wife have accepted willingly or unwillingly.
Whatever the reaction to the birth of a child, it is obvious that the change from the role of husband to that of father is a difficult task. Yet, unfortunately, few attempts have been made to educate fathers in this re-socialization process. Although many good books have been written about American mothers, only recently have some books discussed the role of a father.
It is argued by some writers that the transition to the father’s role, although difficult, is not nearly as great as the transition the wife must make to the mother’s role. The mother’s role seems to require a complete transformation of daily routine and adaptation to a new life, on the other hand, the father’s role is less demanding and immediate. However, even though we have mentioned the fact that growing numbers of women are working outside the home, the father is still thought by many as the breadwinner in the household. According to the author, being a father _______.
| A．brings a feeling of excitement to some men |
| B．has a different meaning for those who have daughters |
| C．makes some men feel proud and others uneasy |
| D．means nothing but more responsibilities. |
It is stated in the passage that ________.
| A．some parents are not prepared to have a child |
| B．young couples do not like children at all |
| C．working couples do not have much time to take care of their children |
| D．many parents look forward to having a boy as their first child |
The transition to the mother’s role requires that the wife _______.
| A．changes her life style in a quite different way |
| B．makes a complete change in her everyday life to deal with the new situation |
| C．stays at home to take care of the baby |
| D．helps her husband in his re-socialization process |
Some writers argue that with respect to the change of roles, fathers, compared with mothers, _______.
| A．have to do more in the household | B．have to make more difficult adaptations |
| C．have an easier job to do | D．can usually do a better job |
The Internet has led to a huge increase in credit-card (信用卡) fraud. Your card information could even be for sale in an illegal web site(非法网站).
Web sites offering cheap goods and services should be regarded with care.
On-line shoppers who enter their credit-card information may never receive the goods they thought they bought. The thieves then go shopping with your card number — or sell the information over the Internet. Computers hackers(黑客) have broken down security(安全) systems, raising questions about the safety of cardholder information.

Ask about your credit-card firm’s on-line rules: Under British law, cardholders have to pay the first US $78 of any fraudulent(欺骗性的) spending.
And shop only at secure sites; Send your credit-card information only if the Web site offers advanced secure system.
If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The Website address may also start https: //—the extra “s” stands for secure. If in doubt, give your credit-card information over the telephone.
Keep your password(密码) safe: Most on-line sites require a user name and password before placing an order. Treat your passwords with care.What do most people worry about the Internet according to this passage?

Right is right. Right? Of course. But is left wrong? Well, the Romans used to think so. They thought left-handed people were mistakes of nature. Latin, the language of the Romans, had many words that expressed this view. Some words we use today still have this meaning. The Latin word “dexter” means “right”. The English word “dexterous” comes from this word. It means “handy” (clever with hands). So, right is handy. But the Latin word for left is “sinister”. The English word “sinister” comes from this word. Sinister means “evil” (very bad). Is it fair to call right-handed people handy and left-handed people evil? Well, fair or not, many languages have words that express such beliefs. In old English, the word for left means “weak”. That isn’t much of an improvement over “evil”.
Not very long ago, children were often forced to write with their right hands. Doctors have since found that this can be very harmful. You should use the hand you were born to use.
People who use their left hands are just starting to get better treatment. But why they get all these bad names in the first place? One reason may be that there are not as many left-handed people as there are right-handed people. There is one left-handed person for every five right-handed ones. People who are different are often thought to be wrong. But attitudes do seem to be changing. Fair-minded right-handed people are finally starting to give left-handed people a hand.What does the passage lead us to believe when one writes?
| A．He can only use his right hand. |
| B．He can only use his left hand. |
| C．He can use either his left hand or his right hand. |

| C．Fair-minded right-handed people are starting to use left hand to write and so on |
| D．Fair-minded right-handed people are starting to give up using their left hands |
After we read the article we can certainly know that _______.
| A．left-handed people have been treated poorly |
| B．the number of the left-handed people is larger than that of right-handed people |
| C．right-handed people are much cleverer than left-handed people |

| C．There are not as many left-handed people as there are right-handed people today. |
| D．“Dexterous” comes from Latin, means “evil” and English “sinister” means “handy”. |
