No one would much like the idea of eating 61 pounds of tomatoes a day. But if their goodness was put into an easy-to-swallow pill that you were told might prevent strokes(中风) and heart attacks you would probably be putting in an order tomorrow.
Researchers believe they may have come up with just that after trials. The daily pill contains a chemical called lycopene which makes tomatoes red and is known to break down fat in the vessels(血管). A Cambridge University study found taking the pills improved blood flow and the lining of vessels in patients with pre-existing heart conditions. It also increased the flexibility(灵活性) of their vessels by 50 percent. The scientists believe it could limit the damage caused by heart disease-responsible for 180,000 deaths a year-and help cut the 49,000 deaths a year from strokes. They also hope it could benefit those with arthritis(关节炎), diabetes(糖尿病) and even slow the progress of cancer.
Each pill is equal to eating around 61 pounds of ripe tomatoes. Studies have shown eating a Mediterranean-style diet rich in tomatoes fish, vegetables, nuts and olive oil can significantly reduce cholesterol(胆固醇) and help prevent cardiovascular disease.
Preliminary results from a two-month trial, in which the pill was given to 36 heart disease patients and 36 healthy volunteers with an average age of 67, were presented at a meeting of the American Heart Association. It was shown to improve the function of the endothelium- the layer of cells lining blood vessels. It also improved their sensitivity to nitric oxide, the gas which causes the enlargement of the vessels in response to exercise.
Ian Wilkinson, head of Cambridge University’s clinical trials unit, said “These results are potentially very significant and it meets the goal, but we need more trials to see if they translate into fewer heart attacks and strokes.”
Further studies are planned, with researchers hoping it could offer a choice for heart disease sufferers who can not take the cholesterol-lowing drugs.
Mike Knapton, head of the British Heart Foundation, said, “Although this showed lycopene improved blood flow in people with heart disease, that’s a long way from demonstrating that taking it could improve outcomes for people with heart disease. The best way to get the benefits of a good diet is to eat plenty of fresh fruit and vegetables.”What can we infer from Paragraph 1?

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly-held image of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past. “We were surprised by just how positive today’s young people seem to be about their families,” said one member of the research team. “They’re expected to be rebellious (叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation and discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-year-old Daniel Lazall, “I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it.” Susan Crome, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments, “Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”What is the popularly- held image of teenagers?
| A．They worry about their school life. |
| B．They live in harmony with their parents. |
| C．They have to be locked in to avoid making troubles. |
| D．They quarrel a lot with their parents. |

According to the author, teenage rebellion _______．
| A．may be a false belief |

People in South Korea who feel they can no longer bear the stress of everyday life now can choose to stay in a prison to relax and think deeply.
In a society where pressure to do well in school and find highly-paid jobs is intense, a former lawyer came up with an extreme relaxation idea. Kwon Yong-seok created the “Prison Inside Me”—a stress-reduction center with a punishment theme. People come here to cut themselves off from the outside world and pay to be kept in 60-square-foot (5.6-square-meter) cells (囚室).
Located on the outskirts of Hongcheon, about 58 miles (93 km) northeast of Seoul, “Prison Inside Me” came to life after Mr. Kwon voluntarily asked to spend time behind bars for “healing reasons,” but his request was turned down. “I didn’t know how to stop working back then,” he said. “I felt like I was being swept away against my will, and it seemed I couldn’t control my own life.” So, Kwon and his wife Roh Ji-hyang decided to take matters into their own hands, and designed and built a prison-like spiritual center. The construction was completed in June last year and cost about 2 billion won ($19 million).
The facility includes 28 cells, furnished with only a toilet, a sink and a small table, where guests can spend time alone, thinking about life and enjoying private thinking periods. Moreover, guests can also join group thinking periods in the hall, where they are given instructions on how to free themselves from what Mr. Kwon calls the “inner prison” to find inner peace.
According to the Wall Street Journal, hundreds of stressed South Koreans are checking in at the stress-reduction facility to think about their lives and regain control of it. A two-night stay at “Prison Inside Me” costs 150,000 won ($146).
Mr. Kwon and his wife explained that at the beginning they had a different plan for the “relaxation center,” and imagined a longer stay for their guests, but, given that people weren’t able to take more time off, they had to reduce the length of stays to just two days.
Park Woo-sub, a guest at “Prison Inside Me,” said the experience helped him a lot. “This is my third time in prison. Being kept in a prison makes me hard to breathe, but it also offers time to focus only on me and spend some quiet time with myself.”
Others said the experience would have been more helpful if the conditions had been poorer, like in a real prison.Paragraph 3 mainly tells us ______.

Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can’t talk, but can they lie in other ways? Can they lie with their bodies and behavior?
Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive.
Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator (猎食动物) gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the “hurt” adult, leaving the baby birds safe in the nest.
Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.
Birds called cuckoos have found a way to have babies without doing much work. How? They don’t make nests. Instead, they get into other birds’ nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.
Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner’s hand and start fighting again.
Chimps are sneaky in other ways, too. When chimps find food that they love, such as
bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don’t hear them, and they don’t need to share their food.
As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her, either.A plover protects its young from a predator by _________

The Brown Bear
My wife Laura and I were on the beach, with three of our children, taking pictures of shore birds near our home in Alaska when we spotted a bear. The bear was thin and small, moving aimlessly.
Just a few minutes later, I heard my daughter shouting, “Dad! The bear is right behind us!” An aggressive bear would usually rush forward to frighten away its enemy but would suddenly stop at the last minute. This one was silent and its ears pinned back---- the sign of an animal that is going in for the kill. And it was a cold April day. The bear behaved abnormally, probably because of hunger.
I held my camera tripod (三脚架) in both hands to form a barrier as the bear rushed into me. Its huge head was level with my chest and shoulders, and the tripod stuck across its mouth. It bit down and I found myself supporting its weight. I knew I would not be able to hold it for long.
Even so, this was a fight I had to win: I was all that stood between the bear and my family, who would stand little chance of running faster than a brown bear.
The bear hit at the camera, cutting it off the tripod. I raised my left arm to protect my face; the beast held tightly on the tripod and pressed it into my side. My arm could not move, and I sensed that my bones were going to break. www..com
Drawing back my free hand, I struck the bear as hard as I could for five to six times. The bear opened its mouth and I grasped its fur, trying to push it away. I was actually wrestling (扭打) with the bear at this point. Then, as suddenly as it had begun, the fight ended. The bear moved back toward the forest, before returning for another attack----- The first time I felt panic.
Apparently satisfied that we caused no further threat, the bear moved off, destroying a fence as it went. My arm was injured, but the outcome for us could hardly have been better. I’m proud that my family remained clear-headed when panic could have led to a very different outcome.The brown bear approached the family in order to _________.
