Passage One
The space shuttle Discovery has safely returned to earth after 2 weeks in earth's orbit. Discovery commander Eileen Collins guided the shuttle to an easy landing at Edwards Air Force Base in California early Tuesday. [26]American Space Agency officials described Discovery's trip as wildly successful. But they refused to say when the shuttle may fly again. The Space Agency has suspended all future shuttle flights until it can discover why a piece of hard protective material broke off from Discovery. A similar incident damaged the Columbia space shuttle in 2003. Columbia was destroyed as it reentered earth's atmosphere.
Japan has marked the 60th anniversary of the atomic bomb attack on the city of Nagasaki. The American bombings of Nagasaki and Hiroshima ended World War II. [27]Nagasaki Mayor Iccho Itoh called for a world ban on nuclear weapons. He urged Americans to ask if the United States needs thousands of nuclear arms to guarantee its security. A short time later, Prime Minister Junichiro Koizumi said he would work to keep Japan free of nuclear weapons.
[28]In Cambodia, an opposition politician has been sentenced to 7 years in prison for plotting to overthrow the government. Cheam Channy was arrested in February after the National Assembly canceled his parliamentary protection from legal charges. He denies any wrongdoing. A court found Cheam Channy and opposition member Khom Peseth guilty. Khom Peseth received a 5-year prison sentence.
Briefly, here again is the major news of the hour.
The American space shuttle Discovery has safely returned to earth.
Japan has marked the 60th anniversary of the atomic bomb attack on Nagasaki. And in Cambodia, an opposition politician has been sentenced to 7 years in prison for plotting to overthrow the government.

答案解析：
Questions 26 to 28 are based on the passage you have just heard.
26. How did American Space Agency officials describe Discovery's trip?
[B]解析：原文說，“美國宇航局官員稱，‘發現號’的旅程獲得巨大成功”。因此選B。本題符合“聽到什么選什么”的解題原則。wildly successful原詞再現，容易聽取。
27. What did Nagasaki Mayor call for?
[A]解析：預讀選項，全是名詞選項，核心詞匯是Japan，world ban，nuclear weapons/research/technology，development，suspending，推測可能問新聞的主題或細節。新聞提到，“長崎市市長伊藤一長呼吁全世界禁止核武器”，聽到什么選什么，由此選A。
28. What was the charge against the two opposition politicians?
[D]解析：第三則新聞開頭即稱，“在柬埔寨，一位反對派因密謀顛覆政府而被判入獄7年”，因此選D。選項都說plotting，只是該“陰謀”的具體內容不同。聽到新聞開頭的"plotting to..."時，集中注意力，就可以聽到D中的"overthrow the government"原詞再現了。
