Exercise 4: Discussionの回答例です
A1. Basically, I think volunteer tourism is good because most volunteers do good conduct. However, I agree with the last two paragraphs. The person who is planning to be a volunteer abroad needs to consider the impact of actions to people in a developing country.
A2. I would spend time teaching in Africa because I am more interested in people than animals and plants. If I were a teacher, I would teach Japanese to students.
A3. The younger people are more interested in overseas than the older people. They can go abroad at cheap rates as mentioned in the first paragraph and they can enjoy seeing new countries, getting to know the local people and culture as mentioned in the forth paragraph.
A4. Of course, I agree with that. Learning a country that you’re planning to visit is helpful for keeping you from danger and restraining your rude behavior.
A5. If I work abroad in the future, I will work in America, Britain or China. Because there are branches of my company in those countries.
