5 Many philosophers have argued that nature has little or no [21] can give it. However, we have failed to place sufficient value on key biological resources. For example, though forests are richest in the tropics, these regions contain many of the poorest countries today. Often, the poverty of the local people is blamed for environmental destruction. However, the weakness of property rights in those countries is a more important, but overlooked, factor. Poor eople often do not care about forests, except as a means to gain immediate benefit. To address this, governments in such poor countries need to establish poor people's rights to the biological riches around them, letting them own and manage these natural areas. [22] surely recognize the benefits of maintaining their forests.

When I was invited to an 次の英文を3分15秒で読んで, 1. の問いに答えなさい。 American woman's house for Christmas, her mother said to me, "We usually don't have a regular breakfast. Will you need breakfast tomorrow?" Out of reserve, I was not able to say "Yes, I will," because (1)that would require her to prepare breakfast for me 5 alone. I had no choice but to say, "No, thank you. (2)Her mother took me at my word, and assumed that I was also in the habit of skipping breakfast. When I was back at the university after the holidays, I (3)brought up the subject with a few Americans. 4)"If you had been in my place, and had needed breakfast, what would you have said?" One person said, "Your friend's mother was being frank, so I'd 00.00% 10 have said frankly, 'If you could prepare a little breakfast, I'm sure I'd enjoy it. (5) Otherwise, I'll eat out." Another person said, "That's not so polite. I'd have asked her politely, 'If you could prepare breakfast for me, I'd appreciate it." They asked me why I had been reluctant to give a frank opinion. I explained the Japanese cultural viewpoint. In Japan, immediately accepting an 15 offer of a meal is regarded as impudent; such an invitation is supposed to be declined at least once. But the host realizes that the guest has declined out of reserve, and makes it a rule to ask a second time. A Japanese guest never insists on being served a meal. The host understands the situation and the feelings of the guest and reacts appropriately. (7) "That idea has no chance at all of working here," one American said with total frankness. She continued, "Unless you're frank here, you'll go hungry all the time."
