【题目】阅读下列短文,从每题所给的四个选项(ABCD)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.”

Travel Light

Getting away for a short time always seems like a great idea—until you have to pack.

【1】 The rule is: pack light. Here are some tips to help you pack.

1. Make a list. Think of what you need from your head to your toes. 【2】 When you’ve done this once, it’ll be easier next time.

2. Consider buying small-size samples of shampoo, toothpaste, and other items at your local drugstore. You can reuse the plastic containers next time you go away too.

3. Choosing which clothes to bring is probably the hardest packing decision to make. Think once again from head to toe — hat, shirts, jeans, sneakers, etc. Once you’ve picked out what you want to bring, think carefully. Do you really need that extra pair of jeans? If so, fine. 【3】 Don’t try to fool yourself. You are the one who will be left holding the bag.

4. Weather is an important factor in your packing. If it’s cold, you could wear a jacket, a - sweater, a regular shirt, and a T-shirt. Putting them on will keep you warm. 【4】 Remember how much easier it will be to carry your bag! As for shoes, you may want to call ahead to see if dress shoes are necessary. If so, one pair will be enough, along with one pair of comfortable shoes. Remember that it is you who have been invited somewhere, not your things. 【5】 So, do it right—pack light.

A. Mixing and matching is a smart and easy way to lighten your load.

B. But packing won’t be a problem if you remember one simple rule.

C. You will have an easier time if you’re weighed down.

D. But make sure they’re really worth the extra weight.

E. It’s best to bring these things with you.

F. And it’ll leave more room in your bag.

G. Keep the list for future reference.
