随堂训练 1 What do a volunteer and a tourist have in common? 1 . But can you be a volunteer and a tourist at the same 2 ? Absolutely. Voluntourism—a trend combining volunteering with tourism—is becoming more and more 3 , with more and more people looking for opportunities to 4 others while visiting interesting places. Many organizations in the world 5 voluntouring projects. Earthwatch, for example, is a non-profit organization focusing on bringing science to life for those 6 about the Earth’s future. It offers opportunities for people to 7 their teams of scientists on a diverse range of projects. It has also set up “teen teams” whereby young people aged 16 to 17 can 8 with, and learn from leading scientists. On the other hand, Habitat for Humanity, a voluntary agency well known for 9 houses for the homeless, has developed a voluntouring package for participants to help out in their projects across the world. They provide 10 housing for the poor. Jimmy Carter, the former president of the USA, is a regular 11 in Habitat for Humanity projects. You don’t have to 12 building skills to be part of its volunteering team; you can give a hand 13 you know how to hold a paintbrush or a hammer. But just like in any other 14 , there are always black sheep that exploit(利用)the 15 of voluntourists. They may come up with phoney(虚假的)programs. Would-be voluntourists should therefore be 16 and check out the organizations before 17 their programs. |
