forget bad experiences. Violence and traffic accidents can leave people with
terrible physical and emotional scars. Often they relive these experiences in
nightmares.
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 frightening experience. They hope it might reduce ,or
possibly erase(抹去),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 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, a professor of psychiatry at Harvard
Medical School. “This could relieve 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 (特质). 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 we want to wipe those memories out," said
Rebecca Dresser, a medical ethicist.

I"ve always wanted to try rock climbing, but never had time or money for it. But I"ve discovered a
way to experience the thrill (兴奋,紧张) of climbing rock. Indoor climbing is an easy and exciting way
to get a taste of rock climbing. And it is also much cheaper and safer! Indoor climbers don"t climb on
real rock, but on a plastic wall. You can probably find a climbing wall near you. Many gyms, schools and
camps have one.
expensive. Most gyms provide the equipment you need. The convenience of indoor climbing is one
reason why it has become so popular. But the main reason people climb is for rush (刺激感) they get.
When I stand at the roof of the wall and look up, I"m always scared, but once I start climbing, fear
changes to determination. With my heart pounding (心剧烈跳动), I reach the top and look down. I
can"t stop grinning. I did it!
Indoor climbing is a great workout (锻炼). Climbing uses muscles (肌肉) that are hard to exercise,
especially those in the shoulders, arms, chest and back. Many people say climbing makes exercise fun.
Most gyms have several climbing walls with various degrees of difficulty. The easier ones are like
climbing a ladder. The difficult ones bulge out (凸出) in places so that climbers must sometimes climb
parallel (平行的) with the floor.
Although gym climbing is easier and safer than real rock climbing, you should still be careful. Always
climb with a partner. As you climb, your partner pulls you climbing rope through something called a
belay device (绳索控制器). The belay catches you if you slip. But make sure your partner knows how
to use this equipment. And if you are a first-time climber, get some instruction before you begin.

homework until very late at night and can’t get up for breakfast the next morning. There are many other
students like Li. They don’t have healthy eating habits. Scientists from Southern University studied 1,790
students in Nanjing last year, according to the Xinhua News Agency. They found that 30% of middle
school students don’t have breakfast and 41.3 percent of students only eat the foods they like most.
These bad eating habits may make the students fatter and affect the development of our bodies. A
study by the Ministry of Health(卫生部) in 2005 showed that about 20 percent of people aged 13 to 20
have a nutritional imbalance(营养失衡).This could cause high blood pressure and other serious problems.
Nutritional balance is important - especially for students. It can prevent health problems like diabetes(糖尿病). Proper nutrition(营养) also gives students enough energy to study.
In order to improve students’ nutrition, many schools in China provide food between meals, such as
milk and fruit. Over half of Chinese middle and primary schools provide nutritious meals.
However, some students don’t like the provided meals and have instant noodles(方便面) or KFC
instead. Hu Yongzhen, an expert from Southeast University, suggests that schools should improve their
nutritional meals in order to attract students. If possible, they should use the help of nutritional experts to
prepare meals for students.

★You shouldn’t eat what you like. You should eat all healthy food including meat, vegetables, fruit,
bread, noodles and milk. every day.
