根据自然资源是存在于自然界、能为人类提供福利的物质与能量,主要包括气候资源、水资源、土地资源、生物资源、矿产资源、海洋资源等,进行分析解答。

我国拥有辽阔的国土,无论蓝色的海洋,还是浩瀚的沙漠,无论绵延的山区,还是奔腾的江河,都蕴藏着多种多样的自然资源。由于我国人口众多,人均资源占有量不足,从这方面看,中国又是一个资源相对贫乏的国家。因此在资源的开发利用中,在控制人口数量的同时,要注意改进技术,提高资源利用率,并开发新材料,新能源。而提倡使用纸杯等一次性生活用品是对资源的浪费;结合题意。故选:A

【题目】 This year, about one hundred teenagers from all over China will spend one year in American homes. They will attend schools and meet teenagers in US., and have a new understanding of America. At the same time, about one hundred American teenagers will come to China to learn Chinese and get a new understanding of China.

A 15yearold exchange student, Fred, spent last year in China with Li Hua's family. In turn, Li Hua spent a year in Fred's home in America.

Students stood up respectfully(尊敬)when the teacher entered the classroom. They took fourteen subjects instead of six in the United States. There were almost no outside activities.

Family life, too, was different. The father's word was law, and all activities were around the whole family rather than individuals(个人)

“Back home, you pick up some friends in a car and go out and have a good time. But in China, you walk home and you have to finish your homework first.”

At the same time, in America, Li Hua, a friendly Chinese boy, was also forming his idea.“I suppose I should criticize(批评)American schools.”he says, “It is much too easy by our level. But I have to say that I like it very much. In China we do nothing but study. Here we take part in many outside activities.”
