Does a drink a day keep heart attacks away? Over the past 20 years, numerous studies have found that moderate alcohol consumption, s ay, one or two beers, glasses of wine or cocktails daily helps to prevent coronary heart disease. Last week a report in the New England Journal of Medicine added strong new evidence in suport of that theory. More important, the work provided the first solid indiction of how alcohol works to protect the heart.In the study, researchers from Boston’s Brigham and Women’s Hospital and Harvard Medical School compared the drinking habits of 340 men and women who had suffered recent heart attack with those of healthy people of the same age and sex. The scientists found that people who sip one to three drinks a day are about half as likely to suffer heart attacks as nondrinkers are. The apparent source of the protection: those who drank alcohol had higher blood levels of highdensity lipoproteins, the socalled good cholesterol, which is known to prevent heart disease.
As evidence has mounted, some doctors have begun recommending a daily drink for patients of heart diseases. But most physicians are not ready to reommend a regular happy hour for everyone. The risks of teetotalling(绝对戒酒) are nothing compared with the dangers of too much alcohol, including high blood pressure, strokes and liver troubles—not to mention violent behaviour and traffic accidents. Moreover, some studies suggest that even moderate drinking may increase the incidence of breast and colon cancer. Until there is evidence that the benefits of a daily dose of alcohol outweigh the risks, most people won’t be able to take a doctor’s prescription to the neighbourhood bar or liquor store.

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.
The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.
Too much packaging is doing serious damage to the environment. The UK, for example, is running out of it for carrying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.
But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But is also applies to a wide range of consumer products, which often have far more packaging than necessary.
There are signs of hope. As more of us recycle, we are beginning to realise just how much unnecessary material are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain t
o climb.

Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes(糖尿病), Thomas would need to inject himself with insulin(胰岛素) three times a day for the rest of his life or risk nerve damage, blindness, and even death. And if that weren't bad enough, he had no health insurance.
After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar , and created diabeticrockstar.com, a free online community for diabetics and their loved ones-a place where over 1,100 people share personal stories, information, and resources.
Jason Swencki's son, Kody, was diagnosed with type diabetes at six. Father and son visit the online children's forums(论坛) together most evenings. "Kody gets so excited, writing to kids from all over," says Swencki, one of the site's volunteers. "They know what he's going through, so he doesn't feel alone." Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases. And more people are being diagnosed at younger ages.
These days, Thomas's main focus is his charity（慈善机构）, Fight It, which provides medicines and supplies to people-225 to date-who can't afford a diabetic's huge expenses. Fight-it.org has raised about $23,000-in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean.
Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full-time job waiting tables. "Of the diabetes charities out there, most are putting money into finding a cure," says Bentley Gubar, one of Rockstar's original members. "But Christopher is the only person I know saying people need help now."

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 tell her the time. She’d had no clocks 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 171bs in weight as a results! 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, on the other hand, are tired during the day and only come to life in the afternoon or evening!
1. 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
2. What is a cause for the change of Stefania’s body clock?
A. Eating fewer meals.
B. Having more hours of sleep.
C. Lacking physical exercise.
D. Getting no natural light.
3. Where does the text probably come from?
A. A novel. B. A news story. C. A pet magazine. D. A travel guide.
Too much TV-watching can harm children’s ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.
One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedrooms TVs.
A second study, looking at nearly 1,000 grown-ups in New Zealand, found lower education levels among 26-year-olds who had watched lots of TV during childhood. But the results don’t prove that TV is the cause and don’t rule out that already poorly motivated youngsters(年轻人)may watch lots of TV.
Their study measured the TV habits of 26-year-olds between ages 5 and 15. Those with college degrees had watched an average of less than two hours of TV per weeknight during childhood, compared with an average of more than 2½ hours for those who had no education beyond high school.
In the California study, children with TVs in their rooms but no computer at home scored the lowest, while those with no bedroom TV but who had home computers scored the highest.
While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating findings that children shouldn’t have TVs in their bedrooms.
1. According to the California study, the low-scoring group might____________.
A. have watched a lot of TV B. not be interested in math
C. be unable to go to college D. have had computers in their bedrooms
2.What is the researchers’ understanding of the New Zealand study results?
A. Poorly motivated 26-year-olds watch more TV.
B. Habits of TV watching reduce learning interest.
C. TV watching leads to lower education levels of the 15-year-olds.
D. The connection between TV and education levels is difficult to explain.
3. What can we learn from the last two paragraphs?
A. More time should be spent on computers.
B. Children should be forbidden from watching TV.
C. TV sets shouldn’t be allowed in children’s bedrooms.
D. Further studies on high-achieving students should be done.
4. What would be the best title for this text?
A. Computers or Television
B. Effects of Television on Children
C. Studies on TV and College Education
D. Television and Children’s Learning Habits
I hated dinner parties .But I decided to give them another shot because I’m in London. And my friend Mallery invited me . And because dinner parties in London are very different from those in New York, “I’m having a dinner party ” means : “I’m booking a table for 12 at a restaurant you can’t afford ang we’ll be sharing the cheque evenly , no matter what you eat.” Wors , in Manhattan there is always someone who leaves before the bill arrives .They’ll throw down cash, half of what they owe, and then people like me, who don’t drink, end up paying even more .

For New Yorkers, talking ,talking about other parts of the world means Brooklyn and Queens in New Yorkers.But at Mallery’s ,when I side that I had been to Myanmar recently, peo ple knew where it was , In New Yorkers people would think it was a usual culb.
