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.”

Top Tips for the Flu Season

It’s coming. I can feel it in the air. On the subway every time someone coughs, I look up to see if I can move a little further. As I exit the train, I immediately reach for hand wash to remove any of the dirt on my hands.【小题1】

If you are young and healthy, it’s most likely that you will just feel uncomfortable for a week or two, miss some work or study. If you are elderly, have medical problems, or are a young child, you may not be so lucky. 【小题2】 Depending on the year, between 3,000 and 49,000 people die.

The best way to prevent the flu is to get vaccinated(接种疫苗). 【小题3】 However, it still offers considerable protection. In adults, the vaccine is 59 percent protective on average. For children the story is better. Clearly, we need better vaccines but it’s still a really good idea to get vaccinated.

Can the flu shot give you the flu? You may have an arm pain or a little fever, but the injection does not contain a live virus and cannot give you the flu.

【小题4】 It isn’t clear how long protection lasts and if the vaccine protects against different flus for only one year.

Finally, here is some advice for what to do if you get the flu.

【小题5】

• Stay at home until your fever has been gone for at least 24 hours. That will reduce the number of people you give this to.

Best wishes for a happy flu season!

A.Flu season is here, and I take it seriously.
B.Oftentimes giving flu shots is fast, easy and effective.
C.If you got the flu shot last year, do you need it this year?
D.If you have the symptoms, call your doctor to prescribe some medicine.
E.Flu symptoms usually include high fever, cough, sore throat and body aches.
F.Each year more than 200,000 people are staying in hospital due to the illness.
G.You may have heard that the flu vaccine didn’t work as well as we thought or would like.

An aspirin a day keeps the doctor away

Dr. Tim Johnson discusses evidence of a daily dose of aspirin’s benefits. That’s not the saying, but doctors have agreed, for about a generation, that an aspirin a day is good for you. It may reduce the risk of heart attacks or strokes by 20 percent or more.

The US Preventive Services Task Force, an independent group convened by the Department of Health and Human Services, has published guidelines that it says should end the confusion.

The key points:

.1. Men should start a daily aspirin at age 45, mainly to protect against heart attacks.

.2. Women should start at 55, mainly to protect against stroke.

.3. For both sexes, a baby aspirin-typically 81 milligram a day-will do the job. There is no evidence that a large dose makes a difference.

.4. And both sexes should stop by age 80, unless their doctors say otherwise. As you get older, there’s a greater risk of bleeding in the brain or the digestive system, a risk that is small but can be deadly in some cases.

If people start taking aspirin as the guidelines, doctors say their risk of heart attacks will drop by about 20 percent. “People may ask themselves ‘Am I at risk for a heart attack or a stroke?’” said Dr. Randal Thomas, director ofcardiovas-cular health at the Mayo Clinic in Minnesota “If. you are age 45 and male, if you’re above age 55 and female, the answer is most likely yes, and you will most likely benefit from taking a small dose of aspirin a day.

【小题1】What might Dr. Tim Johnson think of taking an aspirin a day?
A.It is useless for the old.B.It will keep the doctor away.
C.It is beneficial to health.D.It will have harmful side effects.
【小题2】What can we learn from the guidelines?
A.The aspirin has the same effect on both men and women.
B.A large dose of aspirin will cause bleeding in the brain.
C.People should start taking aspirin at age 45.
D.It will be a waste if you take more than 81 milligram of aspirin a day.
【小题3】What might be Dr. Randal Thomas attitude to the guidelines?
A.Critical.B.Supportive.
C.Cautious.D.Doubtful.
【小题4】What is the text mainly about?
A.How to keep the doctor away.B.How to reduce the healthy risk.
C.What are benefits of aspirin.D.Who should take aspirin and when.

There are 8.8 million blind people in India. In fact, there are 36 million blind people worldwide and a quarter of them are in India; however, many cases of blindness in India are curable. The poor in India have limited access to primary eye healthcare and often do not eat foods rich in micronutrients, like vitamins and minerals, which play an important role in maintaining good eye health.

Many people worldwide are not even aware that they may have a vision (视力) problem simply because they do not get their eyes tested every year with a doctor, who tests for the functioning of the eye muscles (肌肉), as well as common diseases like night blindness. This exam is strongly recommended by experts because some changes in vision, which the patient may take longer to notice, can be found easily in this way.

Certain simple changes in diet and lifestyle can ensure better eye health for you. These include drinking plenty-of water, not smoking, and eating brightly colored and leafy fruit and vegetables. Wearing sunglasses protects your eyes from the sun, which damages otherwise healthy eyes. Learn about your family's eye disease history, and be on the lookout for any problem about your vision. Make sure that you see a doctor immediately for early intervention(干预) if you see any of these signs of worsening eye health.


            If you or a loved one needs to cure blindness or other eye diseases, turn to a crowdfunding (众筹) platform. A group of eye health caregivers have fundraised with crowdfunding platform Impact Guru to raise money to perform operations on the eyes of blind women in south Asia. Running an online fundraiser enables both doctors and patients to find a way out of the dark. If you want eye care to develop, start a fundraiser today.
【小题1】Why are there so many blind people in India?
A.There is a lack of eye hospitals in India.
B.People pay no attention to their eyes at all.
C.Poor Indians lack food good for eye health.
D.The environment damages their eyes.
【小题2】What does the author suggest in Paragraph 2?
A.Examining your eyes annually.
B.Strengthening muscles every day.
C.Raising the awareness of physical health.
D.Attaching importance to self-examination.
【小题3】Which of the following may do harm to your eyes?
A.Smoking a lot.B.Wearing sunglasses.
C.Drinking much water.D.Watching brightly-colored pictures.
【小题4】What does the author want to show in the last paragraph?
