Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences.
Now American researchers think they are close to developing a pill, which help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. 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 releasing 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 wars.
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, a professor of psychiatry(精神病学)at Harvard Medical School. “This could relieve（减轻）a lot of that suffering.”
But those who are against the research say that changing memories is very dangerous because memories give us our identity. They also help us avoid the mistakes in 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 am not sure we’d want to wipe those memories out.” said Rebecca Dresser, a medical ethicist.

Recently we have a hot discussion on if people should keep pets at home in cities or not.                             
Some students think it is a good idea to keep pets because of many old people living alone can get
comfort from them. Beside, getting along well with animals will make our life interested. On the
other hand, other students are against the idea. In their opinions, if too many people keep pets at
home, it’s bad to the environment. What is worse, pets may make too much noisy and even attack
people. I like animals, but I don’t think it bad to keep pets at home. But we must take measures to
keep them polluting our environment.

Little Mark is only 6, but he has an IQ of 200, a genius among geniuses. But his intelligence comes at a cost. His parents must keep him intellectually simulated（启发）while making sure he is like any other little boy.
Mark has been attracted by the way how the world works since he was a baby. When he was 3, Mark was reading fluently, mostly self-taught. His parents haven't been able to keep him away from books since.
"I tried many times to stop him reading. We worry about his crazy fond of reading because he constantly wants to read every-thing whatever it is.”
A psychologist at the Centre for gifted children tested Mark and gave him an IQ of 200. The average child of Mark's age has an IQ of 100. At 200, Mark is a genius-even compared with other child geniuses.
"With children like Mark you can tell that's a bright child as soon as they walk in. They just have this sort of intensity, and maybe they're not so good at communicating with people," the psychologist said. "He will never fit perfectly into a class where he's with children of his age.”
But Mark's mother worries about the "socially isolated" labels. "Nobody wants their child to grow up with that image. I want him to communicate with others freely, but not to be frustrated academically, so it's really hard to find a balance," she says.
Helen Dudeney from the Talented and Gifted Children Association says Mark is one in a million with such a high IQ. She points out that geniuses are still rare and difficult for the public education system to handle. "The lack of coping comes because teachers aren't trained in teaching gifted children," says Dudeney.
Helen believes it's also extremely important for them to be recognized and supported in their talents. Mark's parents are trying to figure out how best to help Mark. At the moment, there are few options. Mark finds first year work boring and simple, but he must learn to complete the work. His mother says, "We just want to be happy. Just to have a happy childhood and want to go to school every day.”

If you want to keep healthy, you should have good habits. What is a habit? It is something we do very often. We don’t even think when we do it. It has become a part of our lives.
“Early to bed, early to rise makes a man healthy, wealthy and wise.” This is an old English saying. Do you know what it means? It means that we must go to bed early at night and get up early in the morning. If we do, we shall be healthy, rich and clever.
Is this true? Perhaps it is. We know the body must have enough sleep. Boys and girls need eight or nine hours’ sleep every day.
Some people go to bed late at night and get up late in the morning. This is a very bad habit. Then you will not think or do your work well. Of course, you can’t be healthy, wealthy or wise.
When we get up early in the morning, we can go out and do morning exercises. Exercise means doing things with the body. Walking, running jumping, swimming, and playing ball games are all exercise. If we don’t exercise, our body will become weak.
Exercise helps the blood (血液) to move around inside our body. Blood takes food to all parts of our body.
Our body also needs air to breathe. Without air, we will die. We must have lots of clean fresh air if we want to be healthy. That is why many people like to go out to do morning exercise.
