Vitamin E supplements(补充品)，which millions take in the hope of longer, healthier lives, may do more harm than good, researchers reported on Wednesday.
In fact, people taking high doses(剂量)of vitamin E may in some cases be more likely to die earlier, although the reasons are not clear, said Dr. Edgar Miller of Johns Hopkins University in Baltimore, who led the study.“I think people take vitamin E because they think it is going to make you live longer, but this(study)doesn’t support that.”Miller told reporters.
Miller and colleagues reanalyzed 19 studies of vitamin E and health between 1993 and 2004. The tests involved more than 136,000 mostly elderly patients in North America, Europe and China. People who took 200 international units of vitamin E a day or more died at a higher rate during the study, which lasted three years, than people who did not take supplements, they told a meeting of the American Heart Association.“It’s about a 5 percent increased risk at 45 years in the tests combined together，”Miller said.“That doesn’t sound like a lot but if you apply it to 25 percent of the (U.S.)adult population taking vitamin E, that is significant.”
Miller, whose findings are also being published online by the Annals of Internal Medicine, said twothirds of people who take vitamin E supplements take 400 IU or more.“We don’t think that people need to take vitamin E supplements, which they can get enough from the diet,”he said. Nuts, oils, whole grains and green leafy vegetables are all rich in vitamin E. People take vitamin E supplements, hoping that________.
| A．they can lose weight easily |

A few years ago, I had the opportunity to play the character of Ronald McDonald for the McDonald's Corporation.
One day each month，we visited hospitals bringing a little happiness to the children there. But there were two rules placed on me during a visit. First, I could not go anywhere in the hospital without permission. And second, I could not physically touch anyone within the hospital. They did not want me to carry germs(细菌)from one patient to another. Breaking either of these rules, I was told, I could lose my job. One day, as I was heading down a hallway and on my way home, I heard a little voice coming through a halfopened door，“Ronald，Ronald.”
I stepped in and saw a boy，about five years old, lying in his dad's arms, Mom with a nurse on the other side. I knew by the feeling in the room that the situation was grave. I asked his name. He told me it was Billy and that I did a few simple magic tricks for him. As I stepped back to say goodbye, he asked me “Ronald, would you hold me？”
At such a simple request, my heart was screaming, “Yes！”But my mind was screaming louder. “No！You are going to lose your job！”
“Hold me” was such a simple request, and yet I searched for any reasonable excuses that allowed me to leave, but none. It took me a moment to realize that in this situation, losing my job may not be the disaster I feared. Then, I picked up this little boy. He was so weak and so scared. We laughed and cried for 45 minutes. With tears in my eyes, I left them. Less than 48 hours later, I received a phone call from Billy's mom that Billy had passed away. She and her husband simply wanted to thank me for making a difference in their little boy's life.
Billy's mom told me shortly after I left the room. Billy looked at her and said, “Momma, I don't care any more if I see Santa this year because I was held by Ronald McDonald.”
For the record, McDonald's Corporation did find it out, but, given the situation，permitted me to go on with my job. I continued as Ronald for another year before leaving the corporation to share the story of Billy and how important it is to take risks.The underlined word “grave” in Paragraph 3 means “________”.
| A．weak | B．serious | C．interesting | D．exciting |
When Billy asked the author to hold him, at first the author ________.
| A．was unwilling to do so | B．was glad to do so |
| C．hesitated to do so | D．hurried to do so |
What lesson did the author draw from his experience?
| A．To amuse others is enjoyable. | B．To take risks is important. |
| C．To break rules is necessary. | D．To be fired is not fearful. |
We learn from the story that ________.
| A．the author left the corporation because he broke the rules |
| B．the author left the corporation because he didn't like the rules |
| C．the boy was quite happy with the experience with the author |
| D．the boy was quite happy with Santa at Christmas |
Because plants cannot move or talk, most people believe that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true.
People who studied plants have found out that plants carry a small electrical charge (电荷). It is possible to measure this charge with a small piece of equipment called “galvanometer”. The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened.
A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them － perhaps by pulling off its leaves or by pulling it out of its pot － then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects (昆虫).
Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room.
Another scientist, named Sauvin, achieved similar results to Backster’s. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them.Backster was surprised at the results of his studies because _____.
| A．he destroyed an insect |
| B．he destroyed a plant by pulling off its leaves |

Advertising is a highly developed twentieth-century industry. The development of radio, television, cinema, magazines and newspapers has gone hand in hand with the development of advertising. Why is advertising so popular? Is it a waste of money? It has been proved again and again that repeated advertising increases product sales. Since it increases production, the price can be reduced. Therefore advertising, instead of making a product more expensive, makes it cheaper.
Advertising is now a scientific business. Once managers would say jokingly, " I know that half of what I spend on advertising is wasted, but I don't know which half." Now, all parts of an advertising program are properly measured and researched.
What makes a good advertisement? There have been major changes in advertising in the past sixty years. People read advertisements partly for information and partly for pleasure. Today's advertisements often start with a question, or a puzzle, with the purpose of attracting the reader's attention. Of course, most advertisements contain information. But this is usually contained in a text that is interesting and often funny. Humor is very important. Sometimes advertisements tell a story, or the story may be continued over a number of advertisements. However, there is a danger in this. It is possible that the reader or viewer will remember the advertisement but not the name of the product.The purpose of advertising is ____.
| A．to increase product sales |
| B．to make a product much better |
| C．to spend more money |
| D．to reduce the production |
Which of the following can be used in place of the underlined phrase "hand in hand" ?
| A．Here and there. | B．Again and again. |
| C．As usual. | D．At the same time. |
What is meant by what managers said in the second paragraph?
| A．A11 the money on advertising was wasted. |
| B．Not all the advertisements were well designed. |
| C．A11 the managers knew about advertising then. |
| D．Managers spent no money on advertising. |
What does the writer think of advertising?
| A．Useless. | B．Unnecessary. | C．Important. | D．Wasteful. |
