PART I    听力部分 

       Nowadays, many of us try to live in a way that will damage the environment as little as possible. We recycle our newspapers and bottles, we take public transport to get to work, we try to buy locally produced fruit and vegetables，and we want to take these attitudes on holiday with us. This is why alternative forms of tourism are becoming popular in the world. There are a lot of names for these new forms of tourism: responsible tourism, nature tourism, adventure tourism, educational tourism and more. Although everyone may have a different definition, most people agree that these new forms of tourism should do the following: first, they should conserve the wildlife and culture of the area; second, they should benefit the local people; third, they should make a profit without destroying natural resources; and finally they should provide an experience that tourists want to pay for.
