I had always wanted to go on a high mountain walk. There are some good long-distance walks in the UK, but there arenˈt any really   (1)   mountains. Before leaving, I   (2)   my clothes, equipment, and the weather forecast. I  (3)   read a couple of books and looked at some photos and travel blogs on the Internet. This was fine, but you canˈt   (4)  

them with the real thing!

A lot of incredible things happened during the   (5)   . Perhaps the best was the complete   (6)   from city life. While I was   (7)  , there were no cars, no noise, no rush. The   (8)   was of course very impressive: valleys, mountain lakes, and there were plants and wildlife that you   (9)  see on TV. And I   (10)  so many interesting people along the way, from Europe, Canada, and Japan. When I arrived at my accommodation, I made new   (11)  . They told me where theyˈd been; I told them where I was going; we exchanged stories and advice. It was just  (12)   !

But of course there were   (13)   . There always are. In this case, the weather. High mountains   (14)  that the weather can change very quickly. We even had snowstorms in July! When your clothes get very wet, it isnˈt   (15)  to dry them, so youˈre  (16)   the next day. And climbing mountains is hard on your knees, too. And thereˈs always the   (17)   of falling on the paths, where not even a mobile phone can   (18)  you very much.

For me, however, the whole walk was a special   (19)   that Iˈll always remember.   (20)   I did the trip again, thereˈs just one other thing I would do differently: lots of physical training before the walk!

It was a hot, sunny day in a national forest.Unfortunately, my best friend, Ned, and I got   (1)  .Once we realized that we were separated from ourgroup, we   (2)  tried to find a safe place to set upour base. We found a small area next to a  (3)   .Then we started a fire with some leaves and sticks  (4)   nearby.

While I was   (5)  the fire, Ned brought more  (6)   , which were put in the water and then slowlythrown into the fire. The  (7)   leaves created a lot ofsmoke. Then we started to write some   (8)   notessaying,“WE ARE LOST! If you find this   (9)  , youwill find us upstream. We are keeping up a(n)   (10)  fire. Please find us!”They were made into paper  (11)   and sent downstream, one every five minutes.We   (12)  that these boats would draw somebodyˈsattention.

  (13)  our group was well on their way, wewanted to be ready for them. Ned and I started to  (14)   two hollow logs (空心圆木) and some strongsticks. Our small fire   (15)  produced plenty ofsmoke. Soon we were very   (16)  to hear whistles (口哨) far in the distance. It must have been thesmoke that worked. Now it was time to start   (17)  on the hollow logs. We enjoyed this part  (18)   we gotto sing and shout along with the beat (节拍). Soonafter, we were  (19)  by our group and we headedback to our camp with a(n)   (20)   story to tell.

       Eco-tourism involves people traveling to beautiful but environmental sensitive places. Such trips are   (1)  carried out with an experienced guide. Over recent years, this type of travel has been steadily gaining   (2)  as more people search for new travel experiences.

      Eco-tourism has many benefits. First, all the   (3)  spent by the tourists is used to   (4)  

the important environmental spots they visit.  Second, it helps  (5)  to better understand the environment, thereby   (6)  their knowledge of the world. Furthermore, this style of travel is also more  (7)  of the local culture.

       Compared to  (8)  tourists, eco-tourists use energy more efficiently, save water and produce less rubbish by finding ways to   (9)  it. These behaviours have a  (10)  and lasting effect on the local environment.

      Two things are needed to make eco-tourism a/an   (11)  . First, it should be done in small groups. And second, because it requires considerable effort, both eco-tourists and locals must be   (12)  in their commitment to improving the environment.

       Green travel provides local people with jobs in parks,   (13)   and shops. One great achievement of eco-tourism has been the   (14)  of illegal hunting. Former hunters can now work as guides to help keep the animals   (15)   in their natural surroundings. Green travel also  (16)  local peopleˈs quality of life, especially childrenˈs.

     Peru is one country using eco-tourism to promote respect for the   (17)   . Itˈs now able to take better care of its rainforests because of a/an  (18)  on more sustainable(可持续的)travel.

           (19)  this, local peopleˈs living-standards have improved. Many others are now following Peruˈs   (20)  and using eco-tourism to preserve their environment for the future generations.
