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．

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 |
“Go for nutrient－dense foods，”she suggests，“foods that contain a multiple of nutrients. For example，select whole wheat bread as a breakfast food，rather than coffee cake. Or drink orange juice rather than orange drink，which contains only a small percentage of real juice—the rest is largely colored sugar water. You just can"t compare the value of these foods, the nutrient－dense ones are so superior，”she emphasizes.
Morrissey believes that variety is not only the spice of life，it"s the foundation of a healthful diet. Diets which are based on one or two foods are not only almost impossible to keep up the strength，they can be very harmful, she says, because nutrients aren"t supplied in enough amounts or balance.
According to Morrissey，trying to find a diet that can cure your illnesses，or make you superwoman is a fruitless search.“ As women，many of us are too concerned with staying thin，”she says，and “we believe that vitamins are some kind of magic cure to replace food.”
“We need carbohydrates，protein and fat－they are like the wood in the fireplace. The vitamins and minerals are like the match，the spark，for the fuel，”she explains.“ We need them all，but in a very different proportions（部分）. And if the fuel isn"t there，the spark is useless.”

| A．it contains only a small percentage of real juice |

What is Mesothelioma?
Mesothelioma is the term used to describe a cancerous tumor found in the mesothelial cells of an organ. The organs where this form of cancer is most commonly found are the lungs, heart and abdominal organs. Pleural Mesothelioma is cancer of the lung lining(组织,膜)and is the most common form of Mesothelioma.
What causes Mesothelioma?
Mesothelioma is almost always caused by exposure to asbestos(石棉). Asbestos is often found in building materials used before the mid 1970"s. In addition, materials such as pipes, boiler insulation, floor, ceiling and roof tiles may contain asbestos.
How much asbestos exposure will cause Mesothelioma?
Generally, the probability of developing this form of cancer is in accordance with the length of time you are exposed to asbestos. Also, your health is at risk if your exposure to asbestos is intense. It should be noted that Mesothelioma has a latency(潜伏)period of 20 to 50 years. This means that you may develop the disease long after your exposure to asbestos. On average, people tend to develop Mesothelioma somewhere between 35 and 40 years after exposure.
How quickly does Mesothelioma progress?
The onset of Mesothelioma is quite slow. Patients will begin to experience symptoms such as lower back pain and chest pain. These symptoms may also be accompanied by weight loss, fever and difficulty breathing. Unfortunately, once Mesothelioma develops, it quickly becomes aggressive and treatment must be sought immediately.
Can Mesothelioma be treated?
Doctors are able to use several traditional methods of cancer treatment for Mesothelioma, including surgery, chemotherapy and radiation. Like all forms of cancer, detecting the disease at the earliest stage possible greatly increases the patient"s chances for survival. If you have worked in an industry such as construction or suspect that you may have been exposed to asbestos, be alert for symptoms and contact your doctor immediately.
What legal courses of action can be taken?
Anyone suffering from Mesothelioma is entitled to compensation from asbestos manufacturers. Additionally, if you are the spouse or child of someone who has died from Mesothelioma, you are entitled to file a claim and seek compensation.
小题1:The authors intends to _______.

Although people have believed depression to be a problem among the rich and educated，studies show that depression is a problem among everyone。Over any six-month period，between five to seven percent of the world"s population will be suffering from a serious depression．
suicide(自***)rates among people suffering from the disease in its extreme，or clinical form were 80 percent higher than in the population at large，and sufferers were four times more likely to have heart attacks. People who suffer from depression often have problems sleeping，getting up on time，and doing work productively．
Depression，which researchers agree has its origin in the genes(基因)，brings loss of confidence and ability to concentrate-making it impossible for employees and managers to work efficiently．
Depression is made more serious in China by Chinese"s inability to face it．Many people believe that depressed people are either weak or lazy． Besides，there is no good treatment，with few specialists available．
“Most patients in China just don"t get help，”a Chinese doctor says．“In my hospital．I have to see 30 or 40 patients in a morning，just have time to say “Hello how do you feel？”
In Western countries，people are not afraid to admit that they have depression，but most do not tell it to their boss，because they fear that their boss would fire them．
“In my experience，aging bosses are the most willing to admit they have it. Because they feel the most secure about themselves，”an American doctor says．
Hopefully，in the near future，people around the world will be able to admit that they have depression so that they can get the right treatment．
小题1:Which of the following is true according to the passage？
| A．It is widely believed that everyone may suffer from depression． |
| B．Depression brings great problems to its sufferers in their life and work |
| C．Depression is a commonly-existing problem only in rich countries． |
| D．The poorer and the less educated a person is，the less he will suffer from depression． |
| A．very unconfident and often absent-minded |
| B．easy to avoid being hit by heart attacks |
| C．working efficiently and productively |
| D．either weak or lazy |
| A．the understanding of the problem |
| B．the lack of treatment and doctors |
| C．their unwillingness to tell it to their boss |
| D．the doctors" careless work |
| A．People are suffering from depression because of the shortage of specialists． |
| B．The aging bosses around the world dare to say they are depressed． |
| C．More and more patients will turn to specialists for help． |
| D．Western people are braver than Chinese people． |
There are two reasons why the physical memory dump happens．The first is pretty simple and is to do with the "hardware", and if any of these pieces are not fit for your system, it will cause the physical memory dump．So, if you"ve recently added any hardware to your PC, then take that out and see if it works．
The other reason is your system, the "registry"．The registry is a big database that operates in the background of Windows, storing all sorts of settings and information about your PC．The problem with the registry is that since it has so many important files inside, it"s constantly got hundreds of files open every time you use your PC．And because there are so many files to open at once, Windows is constantly getting confused, leading it to save many of these files in the wrong way．These files go wrong when saved wrongly, making them difficult for your computer to read．However, if it can"t read the files at all, it has no choice but to stop everything it"s doing and restart your PC．This is why the physical memory dump error appears so easily—because when a registry file is so wrong that it can"t be read, your computer needs to refresh itself immediately．
This latter reason for causing the physical memory dump is actually extremely common and the likelihood is that your PC is suffering from it, if you"re seeing this error．Luckily, it"s also incredibly easy to fix—you just need to use a software tool called a "registry cleaner" to go through the registry and fix all the problems in there．
小题1:From the text we can infer that ________．
| A．the dump error often happens to your PC |
| B．the dump can be dealt with easily |
| C．only the advanced computers suffers from the error |
| D．the dump error can cause the data in your PC to be lost |
A．the hardware loses its memory
B．your Windows needs to be upgraded
C．you have saved wrong files in the PC
D．you have stored too many files in the PC．
小题3:What’s problem with the registry when your PC goes wrong?
A．The register can’t read the files correctly．
B．It must open 100 files every time you use your PC．
C．The register doesn’t agree with the database．
D．The register must save many important files inside．
小题4:What does a registry cleaner means?
| A．A software which can help you save time． |
| B．A software which can remove unnecessary files |
| C．A software which can repair the machine． |
| D．a software which makes your PC down． |
