Jiang Nan, a full-time mother in Beijing, keeps a dozen or so cloth bags at home, carefully selecting one or two before heading out to get groceries. "Most of them were giveaways from advertising marketing campaigns, but others had been handed out in the street by various environmental protection organizations," she explained.
Since June 2008 China has forbidden the production, sale and usage of plastic bags thinner than 0.025 millimeter (毫米), and retailers (零售商) are not allowed to provide free plastic bags to their customers, no matter how thick they are.
Many Chinese consumers like Jiang have learned to refuse plastic bags whenever possible in their shopping. "A plastic bag may only cost a few jiao, but it's more about how bad they are for the environment," Jiang said.
The plastic ban is for the most part well carried out in big cities, and has been obviously effective in reducing white waste. On the first anniversary of the plastic ban Global Village of Beijing, an NGO environmental organization, shows that during the year of the ban the consumption of plastic bags fell by about 40 billion pieces in chain supermarkets alone, saving more than 1.2 million tons of petrol.
However, enforcement (实施) shows rather less muscle in smaller cities, towns and countryside. In a remote town like Lichuan, the awareness of environmental protection is not as strong as that in big cities. Street vendors (街头小贩) worry that they are likely to lose customers if they charge them for plastic bags. Seeing no significance in the issue, local government often turn a blind eye to banned bag trade in the market.
There are still those who don't have an interest in living green. Cui Lin, another Beijinger, often forgets to bring a cloth bag when shopping, and has to buy plastic bags. "Anyway I think plastic bags are neater and cleaner, and I don't mind paying a couple more jiao," he shrugged.
Mrs Yu, a vegetable vendor in Lichuan County, Jiangxi Province, recalled that before plastic bags became popular in the early 1990s, Chinese people always carried a bamboo basket when they visited the market. "Plastic bags are more convenient," she comments, and her view might be that of the tens of millions of people in the nation who still cling to plastic bags, paid or free. This is suggested by her trade where piles of plastic bags are still passed out every day. In Paragraph 1, the writer uses Jiang Nan's case to __________.

On May 23,1989, Stefania Follini came out from a cave at Carlsbad, New Mexico. She hadn’t seen the sun for eighteen and a half weeks. Stefania was in a research program, and the scientists in the program were studying body rhythms (节奏)。In this experiment Stefania had spent 130 days in a cave, 30 feet in depth.
During her time in the cave, Stefania had been completely alone except for two white mice. Her living place had been very comfortable, but there had been nothing to fell her the time. She’d had no clock or watches, no television or radio. There had been no natural light and the temperature had always been kept at 21℃.
The results were very interesting. Stefania had been in the cave for over four months, but she thought she had been there for only two. Her body clock had changed. She hadn't kept to a 24-hour day. She had stayed awake for 20-25 hours and then had slept for 10 hours. She had eaten fewer meals and had lost 17lbs in weight as a result! She had also become rather depressed (抑郁).
How had she spent her time in the cave? As part of the experiment she'd done some physical and mental tests. She'd recorded her daily activities and the results of the tests on a computer. This computer had been specially programmed for the project. Whenever she was free, she'd played cards, read books and listened to music. She'd also learned French from tapes.
The experiment showed that our body clocks are affected by light and temperature, For example, the pattern of day and night makes us wake up and go to sleep. However, People are affected in different ways. Some people wake up naturally at 5:00 am, but others don't start to wake up till 9:00 or 10;00 am. This affects the whole daily rhythm. As a result, the early risers are at their best in the late morning. The late risers, on the other hand, are tired during the day and only come to life in the afternoon or evening! Stefania stayed in the cave for a long time because___________.
| A．she was asked to do research on mice | B．she wanted to experience loneliness |
| C．she was the subject of a study | D．she needed to record her life |
What is a cause for the change of Stefania’s body clock?

| C．Lacking physical exercise. | D．Getting no natural light. |
Where does the text probably come from?
| A．A novel | B．A news story | C．A pet magazine | D．A travel guide |
It was a cold winter day. A woman drove up to the Rainbow Bridge tollbooth (收费站). “I’m paying for myself, and for the six cars behind me,” she said with a smile, handing over seven tickets. One after another, the next six drivers arriving at the tollbooth were informed, “Some lady up ahead already paid your fare.”
It turned out that the woman, Natalie Smith, had read something on a friend’s refrigerator: “Practice random kindness and senseless acts of beauty.” The phrase impressed her so much that she copied it down.
Judy Foreman spotted the same phrase on a warehouse wall far away from home. When it stayed on her mind for days, she gave up and drove all the way back to copy it down. “I thought it was beautiful,” she said, explaining why she’d taken to writing it at the bottom of all her letters, “like a message from above.” Her husband, Frank, liked the phrase so much that he put it up on the classroom wall for his students, one of whom was the daughter of Alice Johnson, a local news reporter. Alice put it in the newspaper, admitting that though she liked it, she didn’t know where it came from or what it really meant.
Two days later, Alice got a call from Anne Herbert, a woman living in Marin. It was in a restaurant that Anne wrote the phrase down on a piece of paper, after turning it around in her mind for days.
“Here’s the idea,” Anne says. “Anything you think there should be more of, do it randomly.” Her fantasies include painting the classrooms of shabby schools, leaving hot meals on kitchen tables in the poor part of town, and giving money secretly to a proud old lady. Anne says, “Kindness can build on itself as much as violence can.”
The acts of random kindness spread. If you were one of those drivers who found your fare paid, who knows what you might have been inspired to do for someone else later. Like all great events, kindness begins slowly, with every single act. Let it be yours!Why did Natalie Smith pay for the six cars behind her?
| A．She knew the car drivers well. |

Since the first Earth Day in 1970,American have gotten a lot “greener” toward the environment . “We didn’t know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.
But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many ,many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports , emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9 .Although serious problems still remain and need to be dealt with , the world is a safer and healthier place .A kind of “Green thinking ” has become part of practices .
Great improvement has been achieved .In 1988 there were only 600 recycling programs ,today in 1995 there are about 6,600 .Advanced lights ,motors , and building designs have helped save a lot of energy and therefore prevented pollution .
Twenty –five years ago , there were hardly any education programs for environment .Today , it’s hard to find a public school , university , or law school that does not have such a kind of program .” Until we do that , nothing else will change! ” say Bruce Anderson .According to Anderson , before 1970, Americans had little idea about ___

Wisdom teeth are normally the last teeth to appear.This usually happens when people are in their late teen years or early twenties，in other words，when they are older and wiser.
Wisdom teeth can grow into place normally and never cause a problem.But often there is not enough room for them in the mouth；they might crowd other teeth.Sometimes they even push sideways through the gums (齿龈)．
An impacted wisdom tooth is one that fails to completely rise through the gums.Wisdom teeth that only partly break through can leave space for bacteria to enter around the teeth.Infection (感染) is a risk in these cases.
Wisdom teeth that are not well lined and become impacted are often removed.The American Dental Association says removal is generally advised when wisdom teeth only partly break through the gums.Removal is also advised if there is a chance that wisdom teeth ate poorly lined.The best time to remove is before the teeth cause any problems or pain.Young adults are the best candidates for wisdom teeth removal.
But why do we have wisdom teeth if we often need to get them removed？One theory has to do with our diets.Scientists say the diet of ancient humans probably required more chewing teeth.Life was probably a little rougher on the teeth back then，too.So it was good to have extras.According to the passage，which of the following statements is NOT true?
| A．Just older and wiser people can have wisdom teeth. |
| B．Wisdom teeth can cause problems if not in their right place. |
| C．Impacted wisdom teeth can’t grow out of the gum fully. |
| D．Wisdom teeth that only partly break can get bacterial infections. |
Wisdom teeth should be removed________.
| A．when they break through the gums |
| B．when they are below the gums |
| C．if they are not well lined or get impacted |
| D．if they take up enough room in the mouth |
We can learn from the passage that________.
| A．impacted wisdom teeth have the risk of getting infected |
| B．ancient humans need chewing teeth because of their happy life |
| C．older adults are the best candidates for wisdom teeth removal |
| D．more chewing teeth are needed for the diet of modern humans |
The main purpose of the passage is to________.
| A．advise | B．persuade | C．comment | D．introduce |
