___46___ to the researchers, there is only one chance in a hundred that their findings could be explained by chance alone. Lead author Dr Beatrice Golomb, from the University of California at San Diego, said: "Our findings appear to add to a body of information suggesting that the composition of calories, not just the number of them, matters for determining their ultimate impact on weight."This is not the first time scientists ___47___ that chocolate may be healthy for us. Other studies have claimed chocolate may be good for the heart. Consumption of certain types of chocolate has been linked to some favourable changes in blood pressure, insulin（胰岛素）sensitivity and cholesterol（胆固醇）level. And chocolate, ___48___ dark chocolate, does contain antioxidants（抗氧化剂）which can help to mop up harmful free radicals - unstable chemicals that can damage our cells.
Dr Golomb and her team believe that antioxidant compounds, called catechins（儿茶素）, can improve lean muscle mass and reduce weight ___49___ studies in rodents would suggest this might be so. Mice ___50___ for 15 days with epicatechin (present in dark chocolate) had improved exercise performance and observable changes to their muscle composition.They say clinical trials are now needed in humans to see ___51___ this is the case.
But before you reach ___52___ a chocolate bar, there are still lots of unanswered questions. And in the absence of conclusive evidence, experts advise caution.While there"s no harm in allowing yourself a treat like ___53___ now and again, eating too much might be harmful because it often ___54___ a lot of sugar and fat too.And if you are looking to change your diet, you are ___55___ to benefit most from eating more fresh fruits and vegetables.

Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programmes. The group that tolerated (忍耐) the pain for the longest time was the group which listened to a funny programme. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.
As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

| A．Laughter is good for health. |
| B．Laughter can make you become old quickly. |
| C．Laughter helps to reduce pain. |
| D．Laughter, just like physical exercise, is good for our body. |
| A．delays | B．prevents | C．increases | D．reduces |
| A．Because they want to earn more money. |
| B．Because they think they will help the patients recover from illnesses. |
| C．Because they want to improve their patients’ health. |
| D．Because they want their patients to laugh more. |
| A．laugh as much as possible |
| B．watch more funny films |
| C．smile all the time |
| D．spend time in the laughter clinics |
| A．Both laughter and physical exercise are good for health. |
| B．Laughter clinics can help patients improve their condition. |
| C．Laughter can reduce the effect of pain. |
| D．Laughter is the best medicine. |
They call be surprisingly vivid and real，or fragmented and weird．They can be comforting or frightening．Our dreams can tell us a lot about what we are really thinking．Dreams give us an x-ray of our unconsciousness(潜意识)．They tell us，particularly when we are at life’s passages or turning points．
Lisa Oppenheim had the same dream whenever she was about to move to a new home or a new city．It’s always just a feeling of needing to stay safe．Experts say disturbing dreams often occur around major life events．For Lisa，it was moving．For others，it can be marriage or divorce，the death of a loved one or pressure at work．
Doctor Siegel has studied the meaning of dream for nearly 30 years．He believes stressful or upsetting dreams can be a sign of what’s buried deep inside our minds．
He said．“Dreams are important to survival．They are crucial to the balance of our psyche(心灵)．They help us work out problems that we’re having every single day．They go to the cutting edge of what’s stressful，what’s bothering us and what we’re working out in our lives．Dreams can guide us and in order to find that guidance，to find that deep source of wisdom that’s in our dreams every night，we need to pay attention to our dreams．”
But many dreams are scary and horrible．How can we understand these nightmares? Doctor Siegel says they are reflecting especially intense emotion or unresolved conflict．The stronger the emotion in the dream，whether it’s pleasure or fear，the likelier the dream is to be important．
Knowing what your recurring dreams or nightmares mean can be liberating．Some nightmares can be a sign of serious psychological problems，such as post-dramatic stress disorder．If they are extremely disturbing or violent or the cause of severe anxiety，you should see a professional therapist(治疗专家)．
小题1:By saying “Dreams give US an x-ray of our unconsciousness,” the author means that dreams
| A．do harm to our mind | B．show us our real mind |
| C．solve our stress in mind | D．give us a turning point in mind |
| A．1ive with great pressure or have great events |
| B．do the same things all their lives |
| C．move to a new home or a new city |
| D．are comforted or frightened |
| A．Dreams play a very important role in the world’s balance． |
| B．Dreams help us find out the problems we need to solve． |
| C．We should pay attention to every dream we have． |
| D．Only the dreams with pleasure are important to us． |
| A．We should remember them because they are important to us． |
| B．We can ignore them since they are just reflecting our emotions． |
| C．We need to take some sleeping pills to stop this serious problem． |
| D．We should see a psychological doctor if they are seriously disturbing |
| A．to introduce a variety of dreams |
| B．to offer some advice on avoiding nightmares |

Obesity related ailments — diabetes, heart disease, kidney failure — consume at least 9 percent of health-care spending the United States. Some researchers believe the cost may be twice that estimate. Total health spending is about $2.6 trillion a year.
In 2030, 42 percent of people are projected to be obese, and 11 percent severely obese. Obesity is a body mass index , which suggests 85 kg for someone 1.67 meters tall. Severe obesity is 112 kg for someone that height.
Obesity is rising in higher-income men. Severe obesity is increasing in both sexes. It was 6.2 percent in women in 1999 and 8.1 percent in 2010. For men, it was 3.1 percent in 1999 and 4.4 percent in 2010.
It is believed that the obesity rate is closely related to the following factors: the price of gasoline, which discourages walking when it is low; access to the Internet (and other technologies), which encourages long periods of sitting still; and restaurants per 10,000 people, which increases eating out and weight gain when the number goes up.
Urgent measures must be taken to inspire people to exercise more and educate people about better eating habits before too many people will be suffering from being . obese.
小题1:The word “ailments” in the second paragraph is equal to _______.
| A．Diabetes | B．Heart disease | C．Kidney failure | D．Diseases |
probably _____ according to the passage.
| A．Obese | B．Severely obese | C．Normal | D．Overweight |
| A．People are used to eating out in restaurants. |
| B．People do not have free access to the Internet. |
| C．The price of gasoline is going up steadily. |
| D．The number of higher-income women is on the increase. |
The study offered two new results from earlier findings, It said taking one aspirin pili every other day helped only healthy men over the age of fifty．It also said aspirin gave the greatest protection against heart attacks to men with low blood cholesterol（胆固醇）levels．
Earlier in the United States began a major aspirin study in the early 1980s．It included 22,000 healthy men doctors．Ail were between the ages of forty and eighty-four．More than 11,000 of the doctors took a harmless pill that contained no drug．The men did not know which kind of pill they were taking．
The doctors who took aspirin suffered 44% fewer heart attacks than those taking the harmless pill．139 men who took aspirin suffered from heart attacks．Ten of them died．239 men who did not take aspirin suffered from heart attacks．Twenty-six of them died．
The researchers said the doctors" study provides clear proof that taking aspirin can prevent a first heart attack in healthy, older men．They said, however, the result does not mean every man over the mage of fifty should take aspirin．They said aspirin couldn"t help men who do not eat healthy foods, who smoke cigarettes and who are fat．The researchers said men who think they wou3d be helped by taking aspirin should talk with their doctors first．
小题1:We may learn that the new use of aspirin is ______．
| A．to treat heart disease |
| B．to reduce the chance of a heart attack in old men |
| C．to protect old men |
| D．to reduce the blood cholesterol levels |
| A．are older and healthy |
| B．know how to keep fit |
| C．are fat and smoke cigarettes |
| D．are suffering from heart attack |
| A．as we like | B．with care | C．every day | D．if we are over fifty |
| A．7% | B．19% | C．11% | D．44% |
The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s. “This gender（ 性别） difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.
小题1:The underlined word “longevity” in the second paragraph probably refers to “________”.
| A．health | B．ageing | C．long life | D．effect |
| A．men’s heart cells | B．women’s ageing process |
| C．the gender difference | D．hearts and long life |
| A．women have more cells than men when they are born |
| B．women can replace the cells that enable the heart to beat |
| C．the female heart loses few of the cells with age |
| D．women never lose their pumping power with age |
| A．exercise regularly to keep your heart healthy |
| B．find out the reason for ageing |
| C．enable your heart to beat much faster |
| D．prevent your cells from being lost |
| A．the reason why ageing takes a greater loss on the male heart has been found out |
| B．scientists are on the way to finding out why the male heart loses more of the cells |
| C．the team has done something to prevent the male from suffering the greater loss |
| D．women over 70 could lose more heart cells than those at the age of 20 |
