Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health. They analyzed data collected from more than 400，000 Americans ages 50 to 70 participating in the study. "We found that the coffee drinkers had a modestly lower risk of death than the non-drinkers， he said. Here"s what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study when the researchers looked at specific causes of death, coffee drinking appeared to cut the risk of dying from heart disease, lung disease injuries, accidents and infections.
Now, Freedman stressed that the study doesn"t prove coffee can make people live longer .A study like this can never prove a cause-and-effect relationship. All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffee is really good for you, scientists have no idea why.

举一反三
Although a diet high in fruit and vegetables can reduce the risk of many diseases, Americans just aren’t getting enough. In fact, since 2000, the amount of vegetables Americans are eating has stayed the same and the amount of fruit Americans are eating has gone down. The CDC also finds that only about a third of adults are eating their expected servings of fruit, and just over a quarter of adults are eating their expected servings of vegetables.
So why aren’t Americans getting their expected servings of fruit and vegetables? It turns out that Americans might be spoiled when it comes to their produce. A national survey conducted by Fruit2day reveals that nearly half of Americans leave fruit in their fridges until it rots with people in Boston among the worst and those in New York and Los Angeles among the best. Sadly, most Americans admit to leaving fruit in the fridge for more than a week.
There are many reasons why Americans don’t eat their fruit or vegetables, including the inconvenience of having to wash or peel it. Fruit2day offers consumers a surprising and convenient way to enjoy the goodness of fruit.
“With no added sugar, natural juices and two full servings of fruit, our Fruit2day line has really captured the imaginations of health-conscious consumers who are actively looking to get more fruit in their diets,” said Hanno Holm, president and chief executive officer of Hero-White Wave. “Fruit2day makes getting more fruit in one’s diet easier for any daily snack routine.”
小题1:For 4 million American adults, how many of them are eating two or more servings of fruit a day?
| A．About 1.3 million. | B．About 2 million. | C．About 3 million. | D．About 1 million. |
| A．Americans have been eating fewer vegetables since 2000. |
| B．most Americans eat less fruit to reduce the risk of diseases. |
| C．most Americans prefer fruit to vegetables. |
| D．over 25% of adults are eating three or more daily servings of vegetables. |
| A．In Boston. | B．In New York. | C．In Los Angeles. | D．Not mentioned. |
| A．easily get rid of their bad eating habits |
| B．conveniently have more fruit in their diets |
| C．add sugar and natural juices to their diets |
| D．find another excuse for not eating healthily |
| A．they are relatively forgetful |
| B．they are too busy with their work |
| C．they don’t think it convenient to eat them |
| D．they prefer daily snacks with added sugar |
| A. A sense of humour is not an inborn ability. B. A sense of humour can be developed in our life. C. A sense of humour helps us from several aspects. D. A sense of humour means more than telling jokes. E. A sense of humour can be expressed in many ways. F. A sense of humour helps people to better enjoy life. |
小题2:Many people mistakenly believe that we are born with a sense of humour. They think that when it comes to a sense of humour. “Either you have got it or you don’t.” This is
false! What is true, however, is that the ability to laugh and smile is actually something we are born with. For example, we laugh when we are tickled under the arm, even without thinking about how to react.
小题3:The parts of the brain and central nervous system that control laughing and smiling are mature at birth in human infants, but that is not the same thing as having a sense of humour. (After all, when a baby laughs in his small bed we don’t rush over and say, “That kid has a great sense of humour!”) Your sense of humour is something you can develop over a lifetime. Don’t be nervous before others and try to laugh at yourself-then you will make them laugh too.
小题4:Humour includes a lot more than laughing and joke telling. Many people worry needlessly that they do not have a good sense of humour because they are not good joke tellers. More than jokes, a sense of humour requires being willing and able to see the funny side of life’s situations as they happen. In fact, one of the best definitions（定义）of a sense of humour is “the ability to see the nonserious element in a situation.”
小题5:There may be a thousand different ways to express your sense of humour, but joke telling is only one of those ways. As more is discovered about how humour benefits our life, more people will be able to see and enjoy the humour when they are in a difficult situation. Life depends on air, food and water, but it is made easier to live with a good sense of humour.
When the person jumps, the cord stretches to absorb (吸收)the energy of the fall, then the jumper flies upwards again as the cord jumps back. The jumper oscillates(摆动)up and down until all the energy is used up.
The word bungee first appeared around 1930 and was the name for a rubber eraser. The first modern bungee jumps were made on 1 April 1979 from the 250-foot Clifton Suspension Bridge in Bristol, by David Kirk, Chris Baker and Alan Weston of the Dangerous Sports Club. The jumpers continued with jumps in the US from the Golden Gate and Royal Gorge bridges, spreading the concept worldwide. By 1982 they were jumping from mobile cranes and hot-air balloons. Later they put on commercial(商业的)shows, which began in 1986.
As with any sport, injuries can still happen, and there have been deaths. A relatively common mistake in the cases that may cause death is to use a cord that is too long. The cord should be fully shorter than the height of the jumping place to allow it room to jumper either starts to slow down or keeps speeding up depending upon the speed of falling.
小题1:Which of the following is NOT suitable for bungee jumping?
| A．The fixed-wing aircraft | B．The helicopter |
| C．The hot-air balloon | D．The mobile crane |
| A．who suits bungee jumping |
| B．the principle of bungee jumping |
| C．the material used for bungee jumping |
| D．the danger of bungee jumping |
| A．the weight of the jumper |

| C．the length of the cord |
| D．the speed of the falling |
| A．teach people how to carry out a bungee jumping |
| B．remind people of the danger of bungee jumping |
| C．advise people not to take the risk of bungee jumping |
| D．introduce some knowledge about bungee jumping |
Certain microorganisms（微生物）cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release（释放）poisons that make people sick.
Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.
When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.
Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.
小题1:Which of the following statements is NOT true?
| A．Food when poisoned can make people sick. | B．Food poisoning means death. |
| C．Food poisoning comes in varieties. | D．Food poisoning can be serious. |
| A．are always accompanied by a fever | B．are too common to be noted |
| C．can be noticed within hours | D．can he ignored |
| A．some chemicals | B．low temperatures |
| C．some tiny living things | D．certain natural materials |
| A．mushrooms should not be eaten |
| B．vegetables are safer than meat and seafood |
| C．natural poisons are more dangerous than chemicals |
| D．different types of food should be handled differently |
| A．natural materials are safe in food processing |
| B．chemicals are needed in food processing |
| C．food poisoning can be kept under control |
| D．food poisoning is out of control |
People who smoke could lose around one third of their daily memory, researchers say.
A study by a team at Northumbria University showed that smokers lost more of their memory when compared to non-smokers.
And the research also found that those who kicked the habit saw their ability to recollect information restored to almost the same level as non-smokers.
The study involved more than seventy 18-to-25-year-olds and included a tour of the university’s campus. Those who took part were asked to recall small details, such as a list of songs played at a campus concert and tasks completed at various points－known as real world memory test. Smokers performed badly, remembering just 59 percent of tasks. But those who had given up smoking remembered 74 percent and those who had never smoked recalled 81 percent of tasks.
Dr. Tom Heffernan, who leads Northumbria University’s Collaboration for Drug and Alcohol Research Group, said the findings would be useful in anti-smoking campaigns. He said, “Given that there are up to 10 million smokers in the UK and as many as 45 million in the United States, it"s important to understand the effects smoking has on everyday cognitive（认知的）function-of which prospective memory is an excellent example. ”
“This is the first time that a study has set out to examine whether giving up smoking has an impact on memory. We already know that giving up smoking has huge health benefits for the body, but this study also shows how stopping smoking can have knock-on benefits for cognitive functions too. ’’
The research will now investigate the effects of passive smoking on memory, while Dr. Heffernan and Dr. Terence O’Neil will look into the effects of third-hand smoking－toxins left on curtains and furniture.
