题目内容
【题目】阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
No one would much like the idea of eating 61 pounds of tomatoes a day. But if their goodness was put into an easytoswallow 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.”

【4】C
【解析】试题分析：
【1】推理判断题。文章第一段第二句“But if their goodness was put into an easytoswallow pill that you were told might prevent strokes(中风)and heart attacks you would probably be putting in an order tomorrow.”是解题关键，此句中的their指代61磅西红柿，由此可推知，西红柿有助于预防中风和心脏病。故答案选B。
【2】推理判断题。通过文章倒数第三段中“but we need more trials to see if they translate into fewer heart attacks and strokes”和倒数第二段第一句中“Further studies are planned”可推知，这种药丸还处于试验阶段。故答案选A。
【3】细节理解题。根据文章第四段第一句“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.”可知，参与试验的志愿者中有一些是健康的老年人。故答案选D。
【4】观点态度题。根据文章倒数第三段Ian Wilkinson的评论中的“These results are potentially very significant and it meets the goal”可推知，Ian Wilkinson对目前的试验结果很满意。故答案选C。
