1 Paragraph 1__________.来源：考试大
“No one has ever succeeded in conveying the wonder.. and joy of science as widely ..and few as well.”（对Carl Sagan的赞誉）that praise was given on Carl Sagan when he was honored with (荣获)the public Welfare Medal， the highest award given by the National Academy of Science. On 20 December 1996, Carl Sagan died at age of 62 of pneumonia（肺炎）. In my experience, he was much more than a prominent populariser. He was a brilliant scientist with solid achievements. （对Carl Sagan的赞誉）
B．分析:该段中不断出现与“荣誉”相关的结构，如:praise， the public Welfare Medal， the highest award，a brilliant scientist with solid achievements，因此判断该段是在对Carl Saga进行赞誉，所以判断答案为B（Honor Sagan enjoyed ）。

2 Paragraph 2__________.来源：考试大
I first met Sagan at a meeting （与D中的核心结构First meeting with Sagan呼应）of the AAAS –the American Association for the Advancement of science – where he took part in a session on the Viking Mars Project. When Viking landed on Mars in 1976, it was at a site he had helped select. Then I interviewed him in Washington, D.C., after Mariner had sent spectacular （B级词汇/壮观的）pictures of the Martian surface. Sagan had acted as a head of one of Mariner’s imaging teams. The interview（与D中的核心结构First meeting with Sagan呼应）, “Close-up（特写的） photos Reveal a Turbulent （骚动的） Mars,” appeared in Popular Science in September 1972.
D．分析:在段落中的特殊位置句子中（段首句和段未句）中都发现了与D的核心结构对应的词语/结构，因此判断答案D正确。
A Sagan as a Science Populariser（科学普及作家）
C Sagan’s publications
E Sagan’s criticism on pseudo-science（伪科学）
F Sagan in trouble with other scientists
3 Paragraph 3__________.来源：考试大
I had originally headlined the story “The red planet isn’t dead,” but Sagan asked me to change it. “I’m in enough hot water with some of my colleagues as it is（该句子结构与F呼应）, ” he said, referring to the anger felt by some scientists over his growing fame as a populariser（与A中的核心词呼应）. That fame reached a zenith（顶点） during his 1980 13-part television series “Cosmos,” with an audience of 400 million people in 60 countries. Along the way, he captured Pulitzer Prize for his book The Dragons of Eden.
F 分析:在段落中发现了与A中核心词对应的词，但因为该词在段落中只出现了一次，而且该句子位置并不特殊，所以还得加以印证答案的正确与否。而实际上包含该核心词的句意与选项F呼应，再借助段首句的句意判断F更合适。
