Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
In the United States, the need to protect plant and animal species has become a highly controversial and sharply political issue since the passage of the Endangered Species Act in 1973. The act, designed to protect species' living areas, and policies that preserve land and forests compete with economic interests. In the 1990's, for example, the woodcutters in the Western United States were challenged legally in their attempt to cut trees for timber in the Cascade Mountains. The challenge was mounted to protect the endangered spotted owl(猫头鹰), whose remaining population occupies these forests and requires the intact, ancient forest for survival. The problematic situation set the interests of environmentalists against those of corporations and of individuals who stood to lose jobs. After months of debate and legal battles, the fate of the woodcutters--and the owls--was still undecided in mid-1992. Similar tensions exist between the developed and the developing nations. Many people in industrialized nations, for example, believe that developing nations in tropical regions should do more to protect their rainforests and other natural areas. But the developing countries may be impoverished(使穷困), with populations growing so rapidly that using the land is a means to temporarily avoid worsening poverty and starvation.
Many of the changes to Earth that concern scientists 'have the potential to rob the planet of its biological richness. Global warming, for example, could wipe out species unable to quickly adapt to changing climates. Clearly, protecting Earth's biological diversity is a complex problem. But solutions to humanity's current problems will come only through coordinated international efforts to control human population, stabilize the composition of the atmosphere, and preserve intact Earth's complex web of life.
Why does the author say that the protection of endangered species is a highly controversial issue？
A．To prove the earth was round.B．To gather information for planning space flights.C．Be
听力原文：W: Dad!
M: Yes？ What's the matter, Mary？
W: I'm wondering if I should buy a pair of tennis shoes. I'm going to join the tennis club at school.
M: Why not？ it's good that you're finally playing sports.
W: But I'd like to have Adidas.
M: Adidas？ They' re expensive. The Chicago Bulls wear them, after all!
W: No. All the guys on the school tennis team are wearing Adidas, boys as well as girls.
M: But none of us ever had Adidas 4and we used to play quite well.
W: Here, Dad, is an ad about Adidas. Can I read it to you？
M: Go ahead.
W: Over forty years ago, Adidas gave birth to a new idea in sports shoes. And the people who wear our shoes have been running and winning ever since. In fact, Adidas has helped them set over 400 world records in track and field alone. '
M: Nonsense! The players have to go through a lot of hard training and practice. It's nothing to do with the shoes. They may be comfortable, but ....
W: You're right, Dad. The ad goes on to say 'You are born to run. And we were born to HELP YOU DO IT BET- TER. '
M: Hmm. It may be good for running, but you don't run.
W: Listen, '... Maybe that's why more and more football, soccer, basketball and tennis', see？ 'TENNIS players are turning to Adidas. They know that, whatever their game, they can rely on Adidas workmanship and quality in every product we make. '
M: OK, OK, dear. I know Adidas is good. But how much is a pair in your size？
W: You don't have to worry about that, Dad. I've saved some money since last Christmas. I just want to hear your opinion.
M: That's good. I have been wanting to have a pair of Adidas sneakers myself.
