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.
【小题1】 In Paragraph 1, the writer uses Jiang Nan's case to __________.

A.introduce a topic B.tell a story
C.describe a person D.offer an argument
【小题2】How did Jiang Nan get her cloth bags?
A.She bought them at a low price.
B.She borrowed them from her relatives.
C.She got them for free.
D.She made them herself.
【小题3】Which is NOT the reason why some people still use plastic bags when shopping?
A.Cloth bags are difficult to get and heavy to carry.
B.People's awareness of environmental protection is not strong enough.
C.People don't mind paying a couple more jiao for plastic bags.
D.Street vendors worry that they are likely to lose customers if they charge them.
【小题4】What does the underlined phrase “cling to” in the last paragraph mean?
A.stop usingB.continue to useC.stay close toD.hold tightly
【小题5】What message does the writer mostly convey in the passage?
A.To reduce white waste is urgent.
B.The plastic bag ban has achieved great success.
C.There is still a long way to go for the plastic bag ban.
D.People's awareness of environmental protection should be stressed.

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead. 
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait— I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory, Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical is stronger than the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

Below is a selection from a popular science book.
If blood is red, why are veins (静脉) blue?
Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it's outside the body, when it's sitting in a vein near the surface of the skin, it's more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, your heart or your brain?
Which works harder depends on whether you are busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don't they grow back in grown-ups?
Baby (or "milk") teeth do not last long; they fall out to make room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you're done. When they're gone, they’re gone. This is because nature figures you're set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They simply lose height as their spine(脊柱) becomes shorter and more curved due to disuse and the effects of gravity. Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don't really shrink! It is not that they are growing backwards — their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little or, more often, become more bent and curved.
Why does spinning(旋转) make you dizzy (眩晕的)?
Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you're moving while you're not!
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other newer bits of the brain, we feel more complex emotions than any other animal on the planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s "use it, or lose it”! It's not that exercise makes you healthy; it's more that a lack of exercise leaves your body weak and easily affected by disease.
【小题1】What is the color of blood in a vein near the surface of the skin?

A.Blue. B.Light yellow. C.Red. D.Dark reddish purple.
【小题2】Why do some old people look a little shrunken as they age?

【小题3】Which of the following statements about our brain is true?
A.In the long run, our brain probably works harder than our heart.
B.When our brain senses the spinning, we will fell dizzy.
C.The brains of the other mammals are as complex as those of humans.
D.Our feelings and emotions come from the most developed area in our brain.
【小题4】What is the main purpose of the selection?
A.To give advice on how to stay healthy.
B.To provide information about our body.
C.To challenge new findings in medical research.

Bissel is a small village of the West Sahara. It lies next to a l.5-square-kilometer oasis(绿洲), from where three days and nights are generally required to go out of the desert. However, before Ken Levin discovered it in 1926, none of the Bissel villagers had ever walked out of the desert. Reportedly, they were not unwilling to leave this barren land. Many had previously tried but failed, always somehow finding themselves back at the oasis after several days of trying to walk out.
When interviewed by Ken Levin, an expert at the British Royal College of Sciences, the villagers explained that no matter which direction they walked it always brought them back to the village.Why couldn’t the Bissel villagers walk out of the desert? Levin was very puzzled. He had, by himself, managed to walk north from the village and reach the nearest town in three and a half days. He decided to carry out an experiment to solve the mystery. He and a Bissel villager called Argutel, would walk out of the desert together. They prepared enough water for a half-a-month journey and two camels. But this time Ken Levin didn't bring his compass. Levin would follow Argutel.
Ten days later, they had walked for about 500 miles but were still in the desert. On the 11th morning, an oasis came into their view. They were back at Bissel. Levin now understood why the Bissel people couldn’t escape the desert. They had no knowledge of the North Star, which had for centuries provided sailors and other travelers with a point of direction. In the desert, if a person goes forward relying only on their senses, they will not be able to travel in a straight line. Rather they will travel in a very large circle and eventually track back to where they began. Levin explained to Argutel the function of the North Star and said, “As long as you rest in the daytime and walk towards the brightest star at night, you would be able to walk out of the desert.” Argutel did as he was told. Three days later, he came to the edge of the desert.
Now in the West Sahara, Bissel has become a bright pearl, where tens of thousands of tourists come every year. Argutel’s bronze statue stands in the center of the town. On its base are the words: __________________________.
【小题1】Ken Levin asked Argutel to walk to the north in order to ________.

A.prove that people could walk out of the desert see
B.how far away Bissel was to the edge of the desert
C.tell people not to walk in circles
D.show Argutel was a great person
【小题2】According to the passage, Ken Levin ________.
A.knew Argutel before he came to the village
B.came to Bissel to do experiments on behalf of his college
C.became the first man to walk out of the desert from Bissel Village
D.taught Bissel villagers knowledge of the North Star when he first arrived
【小题3】It can be inferred from the passage that ________.
A.Ken Levin didn’t walk south because it would take more days
B.the use of a compass was necessary to walk out of the desert
C.tourism in Bissel has been greatly developed and improved
D.Argutel became the leader of Bissel after his return
【小题4】Which of the following can most probably be found at the base of Argutel’s statue?
A.A new life starts from the fixed direction.
B.Where there is a will , there is a way .
C.A long journey starts with the first step .

The way we get about has a deep influence on the way we live-affecting where we set up home, work and holiday. So what changes might come in the way we get around? What big ideas are out there, and do they have any chance of coming true?
Personal Air Travel
The idea: flying cars
Developments in light small plane technology will make it possible for everyone to own what are, in fact, flying cars. They will have closed cabins, heating, stereos and room for two people.
You will take off from a field near your home and fly to towns and cities. After landing, you will take off the fixed wing and continue your journey by road just as if you were traveling by car.
Fuel efficient engines and the advantage of being able to travel in the sky will keep costs and the environmental influence down.
Flying for Fun
The idea: Jet Packs
The idea was a hit when a stuntman (特技演员) flew around on one during the opening ceremony of the 1984 Los Angeles Olympics, which was very successful.
You’ll be able to use the equipment-roughly the size of two scuba tanks fastened to your back-for short journeys.
They will be handy for cleaning hard-to-reach windows, arriving in style at a party and shopping.
Taxis
The idea: driverless taxis

Unknown to most Facebook users, the social network actually offers a lot of privacy controls and security features which can help you lock your account, so you can speak freely. If it’s used properly, you’ll never have to worry about whether you will have to “friend” your boss or your mom. You can friend anyone you want while staying comfortable in the knowledge that not everyone gets to see everything you post.
The problem with carrying out these privacy options is that they’re just too confusing for most non-tech clever people to handle. And often, most people don’t want to bother to take the time to learn. To simplify the process, we’re offering one easy step you can take today to help make your Facebook experience safer, more secure, and more private.
Just make “Friend Lists”. Yes, it will take some time, especially if you’re connected to a couple of hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook.
Friend lists, as the name suggests, are lists for classifying your friends into various groups. The nice thing about this feature is that once you set these lists up, you won’t have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list named “Work”, personal friends you’re not very close with into a list called “Acquaintances”, and people you’re related to into a list called “Family”. Those three main categories will separate out the groups of “friends” who you may want to hide some information from.
To create a friend list, click on “Friends” at the top of the Facebook homepage. In the left-hand column, click “Friends” again under the “Lists” section. Now you’ll see a button at the top that says “Create New List”. Click it. In the pop-up that appears, you can name your list and pick members. If you’ve ever shared an application with your friends, the process of doing this will be very familiar.
When you’ve finished making lists, you’ll be able to use them when selecting who can see what (or who can’t!) when configuring (配置) the security settings described below.
【小题1】What function isn’t understood by most people on Facebook?

A.Surfing the Internet. 
B.Setting safety protection. 
C.Sharing personal information. 
D.Making foreign friends. 
【小题2】What can we learn about Facebook according to the text?
A.Its process of privacy-setting is too complex. 
B.It displays everything people post. 
C.It lacks privacy controls and security features. 
D.Its post is designed for technical people. 
【小题3】What advantage can we get from making friend lists?
A.We can avoid our bosses adding us as friends. 
B.We can share applications with friends. 
C.We can separate acquaintances from family. 
D.We can hide different information from different friends.

Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino (厄尔尼诺). The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.
One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe(津巴布韦), Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.
The scientists wrote about their recent work in the publication(出版物)Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.
【小题1】El Nino is known as ___.

A.the changing of the weather in southern Africa
B.the warming of waters in the Pacific Ocean
C.the weather which brings drought(旱灾)to Africa
D.the weather phenomenon(现象)that brings heavy rains to Africa
【小题2】Scientists study El Nino in order that ___.
A.they can provide a kind of early warning to the place that will suffer from drought
B.they can tell why Zimbabwe has little or no rain
C.they can do some research work in this field.
D.they can put all this information into their computers.
【小题3】Which of the following is TRUE according to the passage?
A.Scientists come to understand how El Nino appears.
B.Three scientists from the USA work on this subject.
C.Southern Africa suffered a serious drought and many people died from hunger.
D.El Nino has something to do with Zimbabwe’s poor crops.
【小题4】Which of the following is NOT true according to the article?
A.The computer is used in this research work.
B.Scientists know when an El Nino appears by means of the computer program.
C.The scientists published their results of the research work.
D.Nature is the name of the article written recently by the scientists.
【小题5】What’s the best title for this passage?
A.Appearance of El Nino is Predictable(可预测的)
B.Drought in Zimbabwe
C.Early Warning System
D.Weather in Africa
