A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long held belief that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.
For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish. At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.
During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol（胆固醇）levels.
小题1:The passage is mainly about _________.| A．the high incidence of heart disease in some countries | | B．the changes in people’s diet | | C．the effect of fish eating on people’s health | | D．the daily fish consumption of people in different cultures |
小题2:We can infer from the passage that there are fewer heart disease deaths ________.| A．in countries of the yellow-skin race | | B．in highly-developed countries | | C．in the countries with high consumption of fish | | D．in the countries with good production of fish |
小题3:The phrase “this relationship” in paragraph 6 refers to the connection between _________ and the level of heart disease.| A．the amount of fish eaten | B．regular fish-eating | | C．the kind of fish eaten | D．people of different areas |
小题4:From the passage we know the author is most probably ______.| A．a heart doctor | B．a science researcher | | C．a supporter of healthy eating | D．a university student |

More than 10 years ago, it was difficult to buy a tasty pineapple. The fruits that made it to the UK were green on the outside and, more often than not, hard with an unpleasant taste within. Then in 1996, the Del Monte Gold pineapple produced in Hawaii first hit our shelves.
The new type of pineapple looked more yellowy-gold than green. It was slightly softer on the outside and had a lot of juice inside. But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known. In no time, the Del Monte Gold took the market by storm, rapidly becoming the world’s best-selling pineapple variety, and delivering natural levels of sweetness in the mouth, up until then only found in tinned pineapple.
In nutrition(营养) it was all good news too. This nice-tasting pineapple contained four times more vitamin C(维生素C) than the old green variety. Nutritionists said that it was not only full of vitamins, but also good against some diseases. People were understandably eager to be able to buy this wonderful fruit. The new type of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater.
Seeing the growing market for its winning pineapple, Del Monte tried to keep the market to itself. But other fruit companies developed similar pineapples. Del Monte turned to law for help, but failed. Those companies argued successfully that Del Monte’s attempts to keep the golden pineapple for itself were just a way to knock them out of the market.
小题1:We learn from the text that the new type of pineapple is ______.| A．green outside and sweet inside | B．good-looking outside and soft inside | | C．yellowy-gold outside and hard inside | D．a little soft outside and sweet inside |
小题2:Why was the new type of pineapple selling well?| A．It was rich in nutrition and tasted nice. | B．It was less sweet and good for health. | | C．It was developed by Del Monte. | D．It was used as medicine. |
小题3:The underlined word “fixture” in Paragraph 3 probably refers to something ______.
A. that people enjoy eating B. that is always present
CV. that is difficult to get D. that people use as a gift
小题4:We learn from the last paragraph that Del Monte ______.| A．allowed other companies to develop pineapples | | B．succeeded in keeping the pineapple for itself | | C．tried hard to control the pineapple market | | D．planned to help the other companies |

Are you sometimes a little tired and sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time – about eight hours after you wake up – your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments where there was no night or day. The people in these experiments almost always followed a similar sleeping pattern. They slept for one long period and then for one short period about eight hours later.
In many parts of the world, people take naps(小睡) in the middle of the day. This is especially true in warmer climates(气候), where the heat makes work difficult in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A daily nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional (传统的), people often suffer less from problem such as heart disease.
Many working people, unfortunately, have no time to take naps. Though doctors may advise taking naps, employers do not allow it! If you do have the chance, however, here are a few tips about making the most of your nap. Remember that the best time to take a nap is about eight hours after you get up. A short sleep too late in the day may only make you feel more tired and sleepy afterward. This can slao happen if you sleep for too long. If you do not have enough time, try a short nap – even ten minutes of sleep can be helpful.

According to a famous optical(光学) expert, Alexander, who recently visited Shanghai, the developed countries in Europe and America have made rules that children must wear resinous(树脂) glasses instead of the traditional glasses made of glass. This is because the glass glasses are more likely to do harm to children’s eyesight.
Alexander pointed out: wearing the right glasses as soon as possible is still the best way to cure and put right children’s eyesight problems.
In America and Japan the resinous glasses have taken up 80 percent of the glasses market. And some European countries and America have made it a law that children, teenagers and drivers must wear resinous glasses. Now, about 10 million children in China have different eyesight problems and they need timely treatment.
But still, too many parents are buying the traditional glass glasses for their children. This is mainly because many parents know little or nothing about the good points of the resinous glasses. Besides, the price for the new glasses is a little higher than the traditional ones.

A Brown University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce (确保) bedtime. Instead, it may be that biologically these sleepyhead students aren’t used to the early hour.
“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent (青春期的) sleep at Brown’s School of Medicine.
Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level. she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns.
Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at nigh and sleep later in the morning. But it’s not just a matter of choice –their bodies are going through a change of sleep patters.
All of this makes the transfer from middle school to high school—which may start one hour earlier in the morning ---- all the more difficult , Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescent are up against difficulties when it conics to trying to be up by 5 or 6 a.m. for a 7:30 a.m. first hell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”
