Culture helps human societies survive in changing natural environment．For example, the end of the last Ice Age, beginning about 15,000 years ago, brought a big challenge to which humans had to adapt．Before this time, large parts of the northern hemisphere were covered in great sheets of ice that contained much of the earth' s water．In North America, large animals that wandered the vast tundra （冰原） provided people with food and materials for clothing and simple shelters．When the earth became warm, large Ice Age animals disappeared, and many land areas were covered by rising sea levels from melting ice．But people survived, they developed new technologies and learned how to survive on new plant and animal species． Finally some people settled into permanent villages, durable houses and farms．
Cultural adaptation has made humans one of the most successful species on the planet． Through history, major developments in technology, medicine, and nutrition have allowed people to reproduce and survive in ever-increasing numbers．The global population has risen from 8 million during the Ice Age to about 6 billion today．
However, the successes of culture adaptation can also create problems in the long run．Over the last 200 years, people have begun to use large quantities of natural resources and energy and to produce a great amount of material and chemical wastes．The global population now consumes some important natural resources—such as petroleum, wood, and minerals—faster than nature can produce them．Many scientists believe that in the process of burning fuels and producing wastes, people may be changing the global climate in unpredictable and possibly harmful ways．Thus, the adaptive success of the present-day global culture of production and trade may be temporary．What is the first paragraph mainly talking about?

“China now has 350 million smokers, accounting for one-third of the world total. Chinese smokers now become addicted to nicotine at the age of 19, five years earlier than the average starting age of 24 in 1997,” a report said a couple of years ago.
Of the 1.1 billion smokers all over the world. more than 800 million are in developing countries. And as the world's largest developing country, China also has the largest number of smokers.
Some frightening facts start to appear when we examine who China’s smokers are. Of the 350 million addicts, more than 100 million are under the age of 18, while more than 50 percent of male teachers and doctors are smokers.
Such a high rate of addicts among male teachers and doctors will certainly have a bad impact on the young generation.
Teachers are usually expected to be role models for students who tend to consider whatever they do is right and follow their example. It is very likely that the number of teenage smokers will increase in the near future unless measures are taken to forbid teachers from smoking in front of their students or designate schools as no-smoking zones.
What is truly puzzling is why so many doctors smoke. They are aware of the results of the habit, such as high blood pressure and lung cancer. Their example only helps justify the addiction of so many others.
If educated people set an example by stopping smoking at least in public places. it would be much easier to drive home the notion that it is uncivilized to smoke in public places.
In China, there should also be a national law to ban smoking in public places. These would make a massive contribution to cutting the number of people in China who are smoking themselves into early grave.Which of the following can serve as the best title for the passage?
| A．Time to Kick the Habit |
| B．China Bans Smoking in Public Places |
| C．Smokers in China |
| D．Make People Aware of Smoking |
In developing countries, China has the largest number of smokers, which covers .
| A．one-third of its total |
| B．one-eighth of its total |
| C．1ess than half its total |
| D．more than half its total |
In the writer's opinion, who have influenced young smokers, especially those under l8?
| A．Parents. | B．Teachers only. |
| C．Advertisements. | D．Teachers and doctors. |
Which of the following statements is NOT true according to the passage?
| A．In China. those who get into the habit of smoking seem to be younger and younger. |
| B．More than half of the teachers and doctors are smokers in China. |
| C．The writer suggests schools should be designated as no-smoking zones. |
| D．It is of great benefit to forbid smoking in public places. |
Our need to communicate with each other has been a driving force in the development of technology. In the 20th century we have seen the invention of the radio, television, telephone and fax, and today the Internet has opened up a whole new way of communicating. We now have instant messaging services such as ICQ or China's QQ and chat rooms where people can join group discussions. They mean increasing choices for when, where and how to communicate, and more importantly, with whom.
While most people use the Internet to keep in touch with friends and family, a growing number of people use QQ and chat rooms to meet and chat with strangers. Because the Internet allows a certain amount of anonymity, users can be more open making it easier to make new friends. One user said that everyone is equal online, and age and appearance become unimportant. This makes it easier for people to communicate with each other.
Finding new friends is not the only reason people use chat rooms. The Internet can bring together like-minded people who want to discuss their favourite topics. There are chat rooms for certain sports, types of music, styles of art, in fact, just about any interest you can imagine, and many that you can't! Whatever unusual interest you might have, if you search on the Internet, there is a good chance that you will find someone, somewhere in cyberspace, willing to talk to you about it-right now.
However, there are problems with going online. It is possible for cyber-criminals to steal information such as credit card details while you are online, and there is always the chance that a new friend is not who he or she claims to be. One girl was really disappointed when she discovered that her new cyberfriend who wrote poems for her, was actually copying all the poems from magazines. But for all the problems that might come up, instant messaging services and chat rooms are here to stay, putting in touch with friends, family and strangers of similar interests.People use the Internet to .
A. chat to friends and meet family
B. meet strangers and write poems
C. chat to friends, family and strangersWhat does anonymity (para. 2) mean?
A. The state of being unknown.
B. The state of being friendly.
C. The state of being online.What types of topics will people discuss on the Internet?
A. Sports, types of music, styles of art.
B. All kinds of topics.
C. Only topics that the Internet allows.What is an example of problems with going online?
A. Some people may send you poems copied from magazines.
B. Your credit card details could be stolen.
C. There might be no one to chat with.
In many cultures white is often associated with something positive. A white-collar job, for instance, is the kind of job many people look for, working with your brain and not your hands.
White has a clean and pure image. That is why doctors, dentists, and nurses usually wear white uniforms. Babies are dressed in white at baptisms（洗礼）and brides wear white wedding gowns at weddings. White in these cases is the symbol of innocence or purity.
Sometimes white is used in expressions that are not good. “Whitewash” is one such expression. At first, “whitewash” meant to paint over something with white paint to make it look better. However, it means something different today: to hide or to cover up mistakes or failures.
A “white elephant” is another example of white used in a negative way. In ancient Thailand, a white elephant was regarded as a sacred animal, but it was very expensive to keep. The kings of those days presented a white elephant to the people they wanted to ruin. Once they received this holy, royal animal as a gift, they were not allowed to sell or kill it. Today, a “white elephant” means something that is big, useless, and unwanted. In America, when people want to get rid of their furniture or clothes, they often have a “white elephant sale”.The text is mainly about________.

After years of research and testing, the hybrid car was developed and put on the market. It’s an interesting and exciting new improvement in today’s world as we look for better ways to protect the quality of the air we breathe and conserve our natural resources.
The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which are used to power a car’s engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution.
A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that’s not how it works. The 144 volt battery pack is actually recharged( 充电 ) through the energy that is produced when the car’s brakes are used. This is referred to as “regenerative braking”, because it generates electricity.
Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically ( 自动地；机械地 )shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up.
Have you ever ridden in a car with someone who ran out of gas? That probably wouldn’t happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, “I am low on gas”. When it completely runs out, the warning reads, “YOU ARE NOW OUT OF GAS!” Then the electric power supply kicks in to let the driver travel a few more miles to a gas station.According to the passage, the word “hybrid” refers to ________.
| A．a high tech discovery | B．energy saving |
| C．a new invention | D．a combination of two things |
“Regenerative braking” is an important process of the hybrid car because ________.
| A．it allows the car to come to a quick stop |
| B．it gives the driver a smoother ride |
| C．it produces energy to charge the battery |
| D．it can control the speed of the car |
Which of the following is right about the EPA?
| A．They designed hybrid cars. |
| B．They outlawed (宣布……为不合法) the burning of fossil fuels. |
| C．They set important guidelines that help control pollution. |
| D．Their main purpose is to protect endangered plants and animals. |
Which of the following is the reason for developing hybrid cars?
| A．They use less gas than regular cars. |
| B．They’re safer to drive than most cars. |
| C．They’re more modern than other cars. |
| D．They cost less than regular cars |
HOUSTON (AP) --- A 10-year-old boy fatally(致命地) shot his father Friday, striking him several times as he sat in the front seat of a SUV to pick up the boy from his mother's home for a weekend visit.
