“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine，newspaper, radio and television ads, promising new shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way to add to beauty or desirability.
Often such products are nothing more than money-making things for their promoters. The results they produce are questionable, and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA(Food and Drug Administration)can require proof under the Food, Drug, and Cosmetic Act that is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure(查封)of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings(法律诉讼)，and new devices appear continually. Before buying, it is up to the consumer to judge the safety or effectiveness of such items.It can be inferred that the ads mentioned in the text are . .
| A．objective | B．costly | C．unreliable | D．illegal |
Which of the following is TRUE according to the text?

| A．if it is a drug |
| B．if it is a device |

The effects of air pollution on natural conditions have been a disturbing problem for many years. Some scientists hold the view that the air inside houses may be more dangerous than the air outside. It may even be one hundred times worse.
Most scientists agree that every modern house has some kind of indoor pollution, which can cause a person to feel tired, to suffer eye pain, headache and other problems. Believe it or not, some pollutants can cause breathing diseases of blood and even cancer.
What made us feel relieved is that there’s growing concern about the problem now. It is true that when builders began constructing houses and offices they did not want to waste energy. To do this they built buildings that prevented or limited the flow of air between inside and outside. For the same purpose, man-made building materials were employed to build houses, which are now known to let out some harmful gases.
Facing the serious challenge, scientists have been searching for a way to handle the problem. To everyone’s delight, they discovered a natural pollution control system for building—green plants, though they do not really know how plants control air pollution. Scientists suppose that a plant’s leaves absorb or take in the pollutants and in exchange gives out oxygen through its leaves and tiny organizations on its roots. Therefore they recommend that all buildings should have one large plant or several small plants inside for every nine square meters of space. Because studies indicate that different plants absorb different chemicals, the most effective way to clean the air is to use different kinds of plants. In conclusion, having green plants inside your house can make it a prettier and healthier place. Why not try?Which of the following statements is TRUR?
| A．Outside air pollution is more harmful than the air inside. |
| B．Scientists have discovered how plants control air pollution |
| C．Indoor air pollution may cause diseases including cancer. |
| D．Only large plants can absorb harmful gases indoors. |
According to scientists, some kind of indoor pollution can be found in ________.
| A．every old building |
| B．every modern house |
| C．all kinds of houses |
| D．all kinds of offices |
What does the underlined part “To do this” refer to in Para3?
| A．To build houses and offices |
| B．To limit the air flow inside |
| C．To use man-made materials |
| D．In order not to waste energy |
The reason why we should use different kinds of plants to clean the air is that ___.
| A．plants can drive out all kinds of pollutants indoors |
| B．plants can absorb different harmful indoor chemical |
| C．plants can take in all pollutants inside and outside |
| D．plants may give out more oxygen than people need |

Roughly speaking, teachers in traditional education may feel that students are too young to know much about the world, and have to be told what to do most of the time. By contrast, open education offers teachers quite different feelings. Students are expected to be responsible for their own education—to discover subjects by themselves instead of being made to study them. This way of teaching allows the students to grow independently and to develop their own interests in many subjects. Some students who do badly in a traditional classroom will be happier in an open classroom and enjoy learning. They will not have to worry about grades or rules at all.
However, many students won’t do well in an open classroom. For these students, they will do little in school if there are too few rules. They will not make good use of open education, which is so different from traditional class, because they may have a problem getting used to making so many choices on their own. For them it is important to have some rules to direct them. They may worry about the rules even when there are no rules. In addition to that, some traditional teachers do not believe in open education and do not like it either.
Since both of some good points and bad points of the open education have been explained clearly, you may have your own opinion on the issue. Personally, I think that the concept of open education is good only in theory. In actual fact, it may not work very well in a real class or school. I believe, most students, but of course not all students, need some structure in their classes. They may want and need to have rules.
In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.Open education allows the students to_________________.
| A．grow as the educated |
| B．be responsible for their life |
| C．discover subjects outside class |
| D．develop their own interests |
Open education may be a good idea for the students who __________.

| A．there are too many rules |
| B．they don’t like activities |

When I wandered along a path through woods in the countryside, a small water pool came into my sight ahead. I changed my direction and took the part of the path that wasn’t covered by water or mud to go around it. When I reached the pool, I was suddenly attacked by something several times! It was from somewhere totally unexpected. I was surprised as well as unhurt. The attacker stopped attacking me when I backed up a foot. I couldn’t help laughing when I looked down and found I was being attacked by a butterfly!
Curiously, I took a step forward to see clearly. My attacker dashed towards me again. He rushed towards me at full speed, attempting to hurt me but failed. For a second time, I took a stop backwards when the attacker paused. I didn’t know what to do. After all, it’s just uncommon that one is attacked by a butterfly. I stepped back to look the situation over. My attacker moved back to land on the ground. That’s when I discovered why the attacker was kept charging me. He had a mate and she was dying.
Sitting tenderly close beside her, he opened and closed his wings as if to fan her. I could do nothing but admire the love and courage of that butterfly in his concern for his mate. He had attacked me for his mate’s sake, even though she was clearly dying and I was much larger than he. He did so just to give her those extra few precious moments of life. I shouldn’t have been careless enough to step on her. His courage in attacking something thousands of times larger and heavier than himself just for his mates’ safety seemed admirable. I was moved and rewarded him by walking on the more difficult side of the pool, leaving them undisturbed. He had truly earned those moments to be with his dear mate.
Since then, I’ve always tried to remember the courage of that butterfly whenever I see huge barriers facing me. Why did the writer change his direction while walking down a path?
| A．To get close to a butterfly. |
| B．To avoid getting his shoes dirty. |
| C．To escape a sudden attack. |
| D．To look over the bad situation. |
What made the man feel funny?
| A．Making the attacker pause. |
| B．Being stepped on by his mate. |
| C．Being attacked by a butterfly. |
| D．Discovering the energetic butterfly. |
From this experience the man learned _____.
| A．people should protect butterflies |
| B．how he should deal with attacks |
| C．people should show sympathy to the weak |
| D．what he should do when faced with trouble |
Which of the following word can best describe the butterfly?
| A．Brave | B．Amusing. | C．Careless. | D．Strong. |
We all remember seeing hitchhikers, standing by the side of the road, thumb, sticking out, waiting for a lift. But it is getting rare nowadays. What killed hitchhiking? Safety is often mentioned as a reason. Movies about murderous hitchhikers and real-life crime have put many drivers off picking up hitchhikers. That no single women picked me up on my journey to Manchester no doubt reflects the safety fear: a large, strangely dressed man is seen as dangerous.
But the reason may be more complex: hitchhiking happens where people don’t have cars and transport services are poor. Plenty of people still hitchhike in Poland and Romania. Perhaps the rising level of car ownership in the UK means the few people lift hitchhiking are usually considered strange. Why can’t they afford cars? Why can’t they take the coach or the train?
Three-quarters of the UK population have access to a car; many of the remainder will be quite old. The potential hitchhiking population is therefore small. Yet my trip proves it’s still possible to hitchhike. The people who picked me up were very interesting-lawyer, retired surgeon, tank commander, carpenter, man who live in an isolated farmhouse and a couple living up in the mountains. My conclusion is that only really interesting people are mad enough to pick up fat blokes in red, spotted scarves. Most just wanted to do someone a good turn; a few said they were so surprised to see a hitchhiker that they couldn’t help stopping.
The future of hitchhiking most likely lies with car-sharing organized over the Internet, via sites such as hitchhikers.org. But for now, you can still stick your thumb out (actually, I didn’t do much of that, preferring just to hold up my destination sign) and people-wonderful, caring, sharing, unafraid people-will stop.
In the UK, with its cheap coaches and reasonable rail service, I don’t think I’ll make a habit of it. But having enjoyed it so much, I’m ready now to do a big trip across Europe and beyond. In the 1970s a female friend of my wife’s hitchhiked to India. How wonderful it would be to have another go, though Afghanistan might be a challenge. I wish I’d got that tank commander’s mobile number.The author tried to hitchhike but was rejected by single women drivers because .
| A．they were not heading towards Manchester |
| B．they thought most hitchhikers were dangerous |
| C．hitchhiking had been handed and they didn’t want to break the law |
| D．he was a strong man in strange clothes who seemed dangerous |
Which of the following statements is NOT true according to the passage?
| A．Movies have discouraged people from hitchhiking |
| B．Car ownership levels are lower in Romania than in the UK. |
| C．25% of UK people don’t have access to cars. |
| D．Increased car ownership has reduced the need for hitchhiking. |
The “fat blokes in red, spotted scarves” in Paragraph 3 most likely means .
| A．murderous hitchhikers | B．friendly and talkative hitchhikers |
| C．typical hitchhikers | D．strange hitchhikers like the author |
According to the author, future hitchhikers are more likely to .
| A．visit websites and find people to share cars with |
| B．stand by roads with their thumbs sticking out |
| C．stick out signs with their destinations written on |
| D．wait for some kind people to pick them up |
From the last paragraph, we know that the author .
| A．frequently hitchhikes in Britain |
| B．plans to hitchhike across Europe |
| C．thinks public transport is safer for travel |
| D．is going to contact the tank commander |
