阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。
A
Elephant Conservation
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
Collect the elephants at 6: 30 a.m. Take them to look for food in the forest. Clean the enclosure. Swim with the elephants in the lake in the afternoon. If volunteers want to relax after work, they can watch satellite television.
How this vacation helps
If these elephants hadn't been rescued, they would still be living on the streets of Bangkok. A rural environment is much better for them than an urban environment where there is lots of pollution.
Gorilla Safari
Countries: Kenya, Rwanda, Uganda
Departures: Aug. —Dec., 2—3 departures per month
Extras: gorilla permit £ 220
If you're lucky, you'll see lions, elephants and rhinos on 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 caught a cold, it would 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 permit, this will pay for the protection of the national park.
Polar Bear Watching
Country: Canada
Departures: 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 unusual. The bears wait for the ocean to freeze so they can hunt seals, so 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 Polar Bears Alive Charity.
