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 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.

WASHINGTON -Tofu（豆腐）and Soyaburgers (豆饼) may be coming to American school lunch menus. What will the kids say? “Terrible,” said Greg Dudzinski, 17, of Ripon High School in Wisconsin, as he toured the US capital.
“The regular hamburgers are bad enough, so soyaburgers would be a lot worse, offered Zach Richey, 13, of Scottsboro Junior High in Alabama, another tourist. But the United States government – hoping to reduce the amount of fat that children are eating –has approved the use of soy as a meat substitute in meals for schools and day-care centers.Not all kids dislike the change. Mariel Spano, 17, of sandy Greek High School in New York, also visiting the capital, said she likes soyaburgers：“There is less fat, and they are better for you… They taste the same, and they are just as good.”
The government tried to make soy a meat substitute nearly 20 years ago, but later dropped the idea．At the time, the plan was intended as a cost-cutting move. US Agriculture Department officials say that their purpose now is only to make meals healthier.Schools are likely to increase the amount of soy that is mixed with hamburgers and other foods already on their menus, and they will also be looking for food companies to develop new soy products that children will like. “I can’t see putting tofu on a student’s plate and having a good acceptance. I can see taking a product that is familiar to the students and adding a large amount of soy to it and having it to be acceptable,” said Jill Benza, director of food services for the Mesa, Arizona schools.

A．The difficulty in using soy products for US schools.
B．Various opinions on soy products for US schools.

37．Where did the interviews most probably take place?
A．In food companies. B．In schools.
C．In Washington. D．In some other states.
38．We may learn from the text that _________________________.
A．soyaburgers taste better than hamburgers.
B．hamburgers are healthier than soyaburgers.
C．soyaburgers cost less than hamburgers.
D．hamburgers cost less than soyaburgers.
