問題詳情：
As we enjoy the summer ocean waves along the beaches, we may think nervously about Steven Spielberg's Jaws and the great fear that sharks inspire in us. Yet we are happy to see global efforts to protect the declining number of sharks. The world has realized that we need the species, like sharks, to keep a balanced ecosystem.
Sharks, in particular, are “in” these days. Thanks to good public policy and famous stars such as Jackie Chan and Ang Lee, killing sharks for fin soup is no longer cool.
The demand for shark fins has been rising for decades, threatening sharks with extinction(滅絕)—up to 100 million sharks are killed each year just for their fins. But we have started to reverse the trend, particularly in many areas of the United States and overseas where restaurants once proudly provided delicious shark fins on the menu.
In California, a ban on the sale and possession of shark fin soup has gone into effect this year through the efforts of Wild Aid and other organizations.
Overseas marketing and public efforts featuring posters on public transportation systems and TV ads have been underway for the past few years. These efforts all show signs of success, on both the supply side and the demand side of trade in shark fins.
Actually, stopping the killing of sharks is part of a broader movement to stop the killing of wild animals and the buying and selling of wildlife products. These products come from hunting elephants, tigers and rhinos, besides killing marine life.
Whether it is shark fin soup or ivory piano keys, killing animals is big business. The hunting of elephants in search of ivory tusks for luxury(奢侈的)goods has become a fullscale war. The decrease of African elephant populations is alarming. Together with international partners, the United States is leading the worldwide effort to reduce demand for highend products that rely on killing animals.

【回答】
文章大意：對野生動物的保護正在進行中。
*：D 猜測詞義題。由轉折詞But可知，所在句意為：我們已經開始“扭轉”這一趨勢。
*：B 細節理解題。由第二段第二句話“Thanks to good public policy and famous stars such as Jackie Chan and Ang Lee, killing sharks for fin soup is no longer cool.”可知，成龍和李安使魚翅湯不再流行，所以A項錯誤；由第一段第一句話“As we enjoy the summer ocean waves along the beaches, we may think nervously about Steven Spielberg's Jaws and the great fear that sharks inspire in us.”可知，斯皮爾伯格的《大白鯊》使人們產生了對鯊魚的恐怖，所以C項正確；由最後一段第三句話“The decrease of African elephant populations is alarming.”可知，D項錯誤；由倒數第二段可知，B項正確。
*：A 推理判斷題。由最後一段最後一句話“Together with international partners, the United States is leading the worldwide effort to reduce demand for highend products that rely on killing animals.”可推知，在全世界人們的努力下，更多的動物會受到保護。所以A項正確；其他三項都不對。
