NOT all memories are sweet. Some people spend all their lives trying to forget bad memories. Violence and traffic accidents can leave people with terrible physical and emotional scars.
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a scary events. They hope it might reduce, or possibly erase, the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body producing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war. They say that there are many people who suffer from terrible memories.
“Some memories can ruin people's lives. They come back to you when you don’t want to have them in a daydream or nightmare. They usually come with very painful emotions,” said Roger Pitman.
But those who are against the research say that changing memories is very dangerous because memories make us different from others. They also help us all avoid the mistakes of the past.
“All of us can think of bad events in our lives that were horrible at the time but make us who we are. I’m not sure whether we want to wipe those memories out,” said Rebecca Dresser, a medical ethicist.

What is eBay? The simple answer is that it is a global trading platform where nearly anyone can trade practically anything. People can sell and buy all kinds of products and goods, including cars, movies and DVDs, sporting goods, travel tickets, musical instruments, clothes and shoes — the list goes on and on
The idea came from Peter Omidyar, who was born in Paris and moved to Washington when he was still a child. At high school, he became very interested in computer programming and after graduating from Tuft University in 1988, he worked for the next few years as a computer engineer. In his free time he started Bay as a kind of hobby, at first offering the service free by word of mouth. By 1996 there was so much traffic on the website that he had to upgrade (升级) and he began charging a fee to members. Joined by a friend, Peter Skill, and in 1998 by his capable CEO, Meg Whitman, he has never looked back. Even in the great crashes of the late 1990s, ebay has gone from strength to strength. It is now one of the ten most visited online shopping websites on the Internet
Ebay sells connections, not goods, putting buyer and seller into contact with each other. All you have to do is lake an e-photo, write a description, fill out a sales form and you are in business. The world is your market place. Of course for each item, eBay gets a percentage and that is a great deal of money. Every day there are more than sixteen million items listed on eBay and eighty percent of the items are sold.

I know what you’re thinking: Pizza? For breakfast? But the truth is that you can have last night’s leftovers with it in the morning, if you want to.
I know lots of women who skip breakfast, and they have a ton of different excuses for doing it. Some say they don’t have time. Others think they’re “saving” calories (卡路里), still others say they just don’t like breakfast food .
But the fact is that eating in the morning is very important when you’re trying to lose weight. “Eating anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking, who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, as long as you stick to only one small piece.
Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast, or they just have coffee or orange juice. I say, try heating up last night’s leftovers. It may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow,” I put away the leftovers instead of eating more that night. Try it, and you may save yourself some pre-bedtime calories. And you will watch your body gain the fat-burning effects.
38. The underlined word “leftovers” in Paragraph 1 probably means _________.
A. food remaining after a meal B. breakfast
C. meals made of vegetables D. pizza with fruit

C. If we have pizza loaded with vegetables, we will certainly not gain weight.

40. According to the last paragraph, it is important to_________.
A. eat something for breakfast B. be careful about what you eat
C. heat up food before eating it D. eat calorie-controlled food
41. The text is written mainly for those _________.

There was a story many years ago of a school teacher — Mrs. Thompson. She told the children on the first day that she loved them all the same. But that was a lie. There in the front row was a little boy named Teddy Stoddard. He didn’t play well with the other children and he always needed a bath. She did not like him.
Then Mrs. Thompson got to know that Teddy was actually a very good boy before the death of his mother. Mrs. Thompson was ashamed of herself. She felt even worse when, like all her other students, Teddy brought her a Christmas present too. It was his mother’s perfume (香水)
Teddy said, “Mrs. Thompson, today you smell just like my Mom used to.” After the children left, she cried for at least an hour. On that very day, she stopped teaching reading, writing and math. Instead, she began to teach children.
Mrs. Thompson paid particular attention to Teddy. The boy’s mind seemed to come alive. The more she encouraged him, the faster he improved. By the end of the sixth grade, Teddy had become one of the smartest children in the class.
Six years went by before she got a note from Teddy. He wrote that he had finished high school and she was still the best teacher he ever had in his whole life. He went to college. Mrs. Thompson got two more letters from him with the last one signed: Theodore Stoddard, M.D. (医学博士).
The story doesn’t end there. On his wedding day, Dr. Stoddard whispered in Mrs. Thompson’s ear, “Thank you, Mrs. Thompson, for believing in me. You made me feel important and showed me that I could make a difference.”
Mrs. Thompson, with tears in her eyes, whispered back, “Teddy, you have it all wrong. You were the one who taught me that I could make a difference. I didn’t know how to teach until I met you.”

Malaria, the world's most widespread parasitic（寄生虫引起的）disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't （or can't） seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect （感染）. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.
