　　　 What's your dream vacation? Watching wildlife in Kenya? Boating down the Amazon? Sunbathing in Malaysia? New chances are opening up all the time to explore the world. So we visit travel agents, compare packages and prices ,and pay our money.

　　　 We know what our vacation costs us. But do we know what it might cost someone else? It's true that many poorer countries now depend on tourism for foreign income. Unfortunately, though, tourism often harms the local people more than it helps them.

　　　 It might cost their homes and lands. In Myanmar, 5,200 people were forced to leave their homes among the pagodas(佛塔)in Bagan so that tourists could visit the pagodas.

　　　 Tourism might also cost the local people their livelihood and dignity. Local workers often find only menial(卑微的)jobs in the tourist industry. And most of the profits do not help the local economy. Instead, profits return to the tour operators in wealthier countries, When the Maasai people in Tanzania were driven from their lands, some moved to city slums. Others now make a little money selling souvenirs or posing for photos.

　　　 Problems like these were Observed more that 20 years ago. But now some non-government organizations, tour operators and local governments are working together to begin correcting them. Tourists, too, are putting on the pressure.　　　

　　　 The result is responsible tourism, or “ethical tourism.” Ethical tourism has people at its heart. New international agreements and codes of conduct can help protect the people's lands, homes, economies and cultures. The beginnings are small, though, and the problems are complex.

　　　 But take heart. The good news is that everyone, including us, can play a part to help the local people in the places we visit. Tour operators and companies can help by making sure that local people work in good conditions and earn reasonable wages.

　　　 They can make it a point to use only locally owned hotel, restaurants and guide services. They can share profits fairly to help the local economy. And they can involve the local people in planning and managing tourism.

　 　　What can tourists do? First, we can ask tour companies to provide information about the conditions of local citizens. We can then make our choices and tell them why. And while we're abroad, we can:

　　 　Buy local foods and products, not imported ones.

　　　 Pay a fair price for goods and services and not bargain for the cheapest price.

　　 　Avoid flaunting wealth.

　　　 Ask before taking photographs of people.

　　　 They are not just part of the landscape!

　　　 Let's enjoy our vacation and make sure others do, too.

　　　 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.
