A
（人与自然|新高考4年8考）
                              Elephant reserve
         Country：Thailand
         This is a working vacation at a wildlife centre. Anyone can become a volunteer if he/she agrees to help the elephant keepers with tasks.
Daily tasks
         Gather the elephants at 6:30 a.m. Take them to look for food in the forest. Clean the enclosure (围场). Swim with the elephants in the lake in the afternoon. If volunteers want to relax after work, they can watch TV.
How this vacation helps
        If these elephants hadn’t been rescued, they would still have been living on the streets of Bangkok now. The rural environment is much better for them than the urban environment where there is lots of pollution.
                      Gorilla safari (野外观兽旅行)
         Countries：Kenya, Rwanda and Uganda
         Departure(出发班次)：2 - 3 departures per month from August to December.
        If you’re lucky, you’ll see lions, elephants and rhinos during this safari. The highlight of the trip is the opportunity to see gorillas in the mountain forests. However, you must be in good health — if a gorilla catches a cold, it will be extremely harmful to its whole family.
How this vacation helps
         There are only about 600 mountain gorillas left in the world as human activity has reduced the area where they can live. When you buy a ticket, this will pay for the protection of the national park.
                          Polar bear watching
          Area & Country：Arctic, Canada
          Departure：sixty trips between Oct 1 - Nov 19.
          Every October and November groups of polar bears gather in Hudson Bay. As they are normally lonely creatures, this is not usual. The bears wait for the ocean to freeze so that they can hunt for seals, and therefore this is the perfect opportunity to see them.
How this vacation helps
         If the Arctic ice cap melts due to global warming, polar bears will be in danger. We give a share of our profits to the charity that protects polar bears.
