No one would much like the idea of eating 61 pounds of tomatoes a day. But if their goodness was put into an easy­-to­-swallow pill that you were told might prevent strokes (中风) and heart attacks you would probably be putting in an order tomorrow.

Researchers believe they may have come up with just that after trials. The daily pill contains a chemical called lycopene which makes tomatoes red and is known to break down fat in the vessels (血管). A Cambridge University study found taking the pills improved blood flow and the lining of vessels in patients with pre­existing heart conditions. It also increased the flexibility (灵活性) of their vessels by 50 percent. The scientists believe it could limit the damage caused by heart disease—responsible for 180,000 deaths a year—and help cut the 49,000 deaths a year from strokes. They also hope it could benefit those with arthritis (关节炎), diabetes (糖尿病) and even slow the progress of cancer.

Each pill is equal to eating around 61 pounds of ripe tomatoes. Studies have shown eating a Mediterranean­style diet rich in tomatoes, fish, vegetables, nuts and olive oil can significantly reduce cholesterol (胆固醇) and help prevent cardiovascular disease.

Preliminary results from a two­month trial, in which the pill was given to 36 heart disease patients and 36 healthy volunteers with an average age of 67, were presented at a meeting of the American Heart Association. It was shown to improve the function of the endothelium—the layer of cells lining blood vessels. It also improved their sensitivity to nitric oxide, the gas which causes the enlargement of the vessels in response to exercise.

Ian Wilkinson, head of Cambridge University’s clinical trials unit, said, “These results are potentially very significant and it meets the goal, but we need more trials to see if they translate into fewer heart attacks and strokes.”

Further studies are planned, with researchers hoping it could offer a choice for heart disease sufferers who can not take the cholesterol­lowing drugs.

Mike Knapton, head of the British Heart Foundation, said, “Although this showed lycopene improved blood flow in people with heart disease, that's a long way from demonstrating that taking it could improve outcomes for people with heart disease. The best way to get the benefits of a good diet is to eat plenty of fresh fruit and vegetables.”

1. What can we infer from Paragraph 1?
A.We can eat too much tomato food.

【推荐1】Here’s an idea whose time has come: A flu shot that doesn’t require an actual shot.

For the first time, researchers have tested a flu vaccine patch(疫苗贴) in a human clinical(临床的) and found that it delivered as much protection as a traditional injection(注射). Doctors and public health experts have high hopes that it will increase the number of people who get immunized(免疫的) against the flu.

Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization. A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses “microneedles”. These tiny neddles on a patch are very small. Yet they’re big enough to hold vaccine for three types of flu.

None of the study volunteers had serious side effects. The group that got patches had mild skin reactions that were not seen in the regular needle group, while the volunteers in the regular needle group were more likely to experience pain. Overall, 70 percent of the volunteers who got vaccine patches said they’d rather use them again than get a traditional flu shot. The study authors declared it a success on all fronts.

The biggest beneficiaries(受益人) could be people in low- and middle- income countries, where flu vaccines are hard to come by. Reducing pain is nice, but other benefits—the patch costs less, is easier to transport, doesn’t reqire refrigeration, can be self-administered and doesn’t cause waste of needles- are even better.

“Microneedle patches have the potential to become ideal candidates for vaccination programs,” wrote Katja Hoschler and Maria Zambon of Public Health England.

1. What is the passage mainly about?
A.A vaccine patch that cures people of their flu.
B.A clinical study that protects people from disease.
C.A patch that makes flu shots a thing of the past.
D.A method that makes traditional flu shots painless.
2. What do we know about the vaccine patch?
A.It is prouduced by the WHO.B.It causes slight side effect.
C.It delivers vaccine to the little finger.D.It works badly on people.
3. The new patch has all the following benefits except that ________.
A.it is provided free of chargeB.it can be used without a doctor
C.it can be kept at room temperatureD.it needs less care in transportation
4. What is Katja and Maria’s attitude towards microneedle patches?
A.Disappointed.B.Favorable.
C.Concerned.D.Unacceptable.

文章大意:这是一篇记叙文。文章主要讲述患有马凡氏综合症的Tal Golesworthy拒绝做手术,他用3D打印技术制作出心脏主动脉复制品,通过手术修复了自己的心脏。

【推荐2】When Tal Golesworthy was told he needed a lifesaving heart operation in 1993, he said no. Golesworthy has Marfan syndrome, a genetic condition affecting body tissues.

Back in 1993, his doctor told him that his aorta (主动脉) was so enlarged that it would unavoidably break unless he underwent a major surgery. “The operation really didn’t look attractive,” says Golesworthy. What he particularly didn’t like was having to take a medicine after the operation that would prevent blood clots (血栓) but presented its own risks. “I was riding motorbikes then, and skiing, so my whole lifestyle would have been affected.”

By 2000, however, his condition had worsened. Realizing something had to be done, Golesworthy put his years of experience as a research-and-development engineer with the United Kingdom’s National Coal Board to good use. He decided he would fix himself. “Learning new stuff and developing new ideas, that was my job,” Golesworthy says.

So Golesworthy spent 30 hours in an MRI scanner, used 3D printing to create a copy of his heart aorta, and wrapped it with a special material. Strong determination together with an original yet practical solution won him the support of two leading surgeons who helped him raise the money to develop his idea.

In May 2004, at the age of 47, he became the guinea pig for his own invention. The operation was a success. It has since been used by surgeons in the United Kingdom, Ireland, and the Netherlands. “When you’re as motivated as I was,” Golesworthy said, “you make things happen.”

1. Why did Golesworthy refuse to take the major operation?
A.Because the heart surgery was too risky.
B.Because his way of life would be influenced.
C.Because his aorta would break during the surgery.
D.Because he assumed that it would not save his life.
2. Golesworthy is a person with          .
A.resolution and new ideasB.motivation and magical power
C.curiosity and mental problemsD.optimism and practical lifestyle
3. What does the underlined part in the last paragraph probably mean?
A.An expert in medicine.B.An animal with talents.
C.A subject for experiment.D.A patient with a serious disease.
4. What is the main idea of the text?
A.An engineer became a surgeon.B.A patient invented an operation.
C.A patient never gave in to death.D.An engineer helped fix his own heart.

文章大意:本文是一篇说明文,文章说明了以体重为主的医疗保健中心对人们的不良影响,指出医生不应该只以体重为健康指标,也不要将减肥作为快速治疗健康疾病的手段。

【推荐3】At the start of nearly every doctor’s visit, chances are you will be asked to step on a scale and get your weight measured for that day’s exam record. But many conversations around weight have become an obstacle, not a help, in the campaign to make people healthier.

Higher body masses are associated with increased risk for diseases like hypertension, diabetes and coronary disease. Many studies of hundreds of thousands of patients have shown that heavier people are at higher risk for these illnesses. But the big picture is not the whole picture. Researchers have identified a subset of obese people considered to be “metabolically healthy”—meaning they do not exhibit elevated blood pressure or the diabetes indicator called insulin resistance, for example. Although the numbers vary greatly depending on the study, the “metabolically healthy” population could account for anywhere from 6 to 75 percent of obese individuals.

One interesting report published in 2016 found that a higher body mass index (or BMI, the ratio of weight to height) “only moderately increased the risks for diabetes among healthy subjects” and that unhealthy thin people were twice as likely to get diabetes as healthy fat people. Clearly, there is more to the equation than weight.

Despite such findings, doctors routinely recommend dieting for weight loss as a means to “treat” poor health indicators such as high cholesterol and insomnia in fat patients. Virtually no diet works in the long term. The result: 95 to 98 percent of those who attempt to lose weight fail, and up to two thirds end up heavier than when they began. Spending years trapped in a cycle of losing weight, regaining it, then losing it again is associated with poorer health outcomes. It is time that doctors give up the scale-centric health care practice and focus on behaviors that have proven positive outcomes for health.

Among the more dangerous by-products of weight-centric health care are the increased shame experienced by the overweight. The well-reported anecdotal experience of innumerable fat people is that doctors often prescribe weight loss without examining them, running tests or performing other normal procedures for conditions that thin people would be screened for automatically. Research over the past two decades has shown that health professionals have negative attitudes toward fat people, as the authors of a large review paper wrote in 2013 in Current Obesity Reports. Not only that but doctors’ appointments with fat patients are shorter on average, and physicians routinely use negative words in their medical histories of such people. Such practices keep people from regular annual exams and prevent the detection of serious underlying conditions.

To practice evidence-based medicine, doctors should stop relying on weight alone as an indicator of health. Instead practitioners should focus on behavioral changes to improve health outcomes.

1. By “the big picture is not the whole picture” (paragraph 2), the writer means that_______.
A.there are some exceptions
B.more evidence should be presented
C.some health risk has been neglected
D.people don’t care much about health
2. Why does the writer mention the report published in 2016?
A.To call attention to those who are thin but unhealthy.
B.To explain what “moderately increase” means in real life.
C.To argue against BMI being used as an indicator of fatness.
D.To show that weight may not be associated with poor health.
3. What can be inferred from the passage about fat people?
A.Most of them worry about their weight.
B.Some of them can’t be diagnosed correctly.
C.They need at least one exam every half year
D.They don’t follow doctors’ recommendations.
4. What is the main idea of the passage?
A.Weight-watching health care is common but may do harm.
B.More care should be taken of those overweight people.
C.Fat people are sometimes treated unfairly in society.
D.It’s time that we should be more health-conscious.
