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  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 . A Cambridge University study found taking the pills improved blood flow and the lining of vessels in patients with pre-existing heart conditions. It also increased the flexibility  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 , diabetes  and even slow the progress of cancer. Each pill is equal to eating around 61 pounds of ripe tomatoes. Studies have shown eating a Mediterranean-style diet rich in tomatoes fish, vegetables, nuts and olive oil can significantly reduce cholesterol  and help prevent cardiovascular disease. Preliminary results from a two-month 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 cholesterol-lowing drugs. Mike Knapton, head of the British Heart... We can learn from the passage that the pills   _  . A) are at the experiment stage B) can cure all the disease C) are widely used among patients D) cost patients so little money

One day,I received a call from a colleague.He was about to give a student a zero for his answer to a physical problem,while the student claimed a perfect score.I was elected as their arbiter .I read the examination problem,"Show how it is possible to determine the height of a tall building with the aid of a barometer ." The student had answered,"Take the barometer to the top of the building,attach a long rope to it,lower it to the street,and then bring it up and measure the length of the rope.The length of it is the height of the building." The student had really answered the question completely,but the answer didn't confirm his competence in physics.I suggested the student try again.I gave him six minutes to answer the question,warning that the answer should show some knowledge of physics.Five minutes later,he said he had many answers and dashed off one,which read "Take the barometer to the top of the building and lean over the edge of the roof.Drop the barometer,timing its fall with a stopwatch,then use the physical formula to calculate the height of the building." At this point,my colleague had to accept it,and then the student made almost full marks.I couldn't help asking the student what the other answers were.He listed many others,and then added,"Probably the best one is to take the barometer to the administrator and say to him,'Sir,here is a fine barometer.If you tell me the height of the building,I will give it to you.'" Then,I asked the student if he really did not know the conventional answer to this question.He admitted that he did,but said that he was fed up with high school and college instructors trying to teach him how to think. The name of the student was Bohr who later was famous all over the world.He won the Nobel Prize in Physics in 1922. We know from the passage that  _  . A) the student knew the expected answer B) the administrator told Bohr the height C) the author preferred Bohr's last answer D) the teacher was a very stubborn person

It was the middle of third grade and I was not sure what had got into me. I lied about many things -- I lied that I had eaten all my dinner, when in fact I buried it in the trash can. I lied that I had made my bed, when clearly I had not. My lies were not hurting anyone, but for some reason I felt the need to tell lies on an impulse  that didn't feel like my own. I was labeled a liar. One day my sisters and I were invited to spend the weekend with my aunt. We all loved it. She spoiled us with her time.And she was an amazing artist. She had cool pencils, erasers and other supplies that any young girl would love to get her hands on. Then it happened...someone took one of Aunt Kim's good art erasers and rubbed it across the entire top of the TV. The eraser ruined the shiny finish on the TV's casing. All the three of us were called into the TV room and asked to admit. Nobody did! Aunt Kim told us how disappointed she was. The next thing I knew was that she was on the phone with my parents and they were on their way to picking me up. It had to be me! I was the liar. I argued, but no one listened. And then before dinner there was a knock at the front door! Aunt Kim was standing there. It turned out my younger sister finally felt guilty! She admitted that she was the one who rubbed the eraser on the TV. I was invited back! A lie may take care of the present, but it has no future. No matter how big or small your lies are, once you are labeled a liar, earning trust takes a lot of work and time. Why does the author tell lies? A) She just does that out of a strong desire. B) She can find pleasure in telling a lie. C) She is afraid to admit her mistakes. D) She likes to play tricks on others.
