describing his career，Meldal said he started out as an engineer but changed to chemistry because he “wanted to understand the world”． Meldal's experience may come as a surprise to students.They might believe they have to center their work and school lives in one field to be successful.But a study from professors at Michigan State University shows that is not always the case. Michele Root-Bernstein and Robert Root-Bernstein (her husband) published their study in the Creativity Research Journal.They said that a large number of Nobel Prize winners can be described as “polymaths”． The writers looked at past Nobel Prize winners and their students.They decided that when students of winners go on to win Nobel Prizes，some of what they learned from their teachers is how to live a life with many interests.They are，in a way，learning how to be creative. Having many interests，the Root-Bernsteins wrote，permits scientists to look for creative ways to solve problems.In fact，one important part of science is not discovering answers，but recognizing problems that need to be solved. The prize winners，the Root-Bernsteins said，transfer “skills，techniques and materials from one field to another.” They said Alexis Carrel won his Nobel Prize in Physiology or Medicine in 1912 by using techniques he learned from the clothing business.He realized that people who used thread to make and fix clothing had a skill that could be used in operations to put new organs into people's bodies. The Michigan State University professors study creativity.They found Nobel winners are nine times more likely to have experience in working with wood，metal or in the arts than most scientists.The researchers say that unlike many people who spend long hours at work and give up some of their outside interests，Nobel winners believe their hobbies are important to creativity. [语篇解读]　本文是一篇说明文。研究发现，许多诺贝尔奖获得者都是博学多才的人，他们有广泛的兴趣爱好，而这对提高创造力非常重要。 1．Which aspect of Meldal surprised students? A．His winning Nobel Prize. B．His original working field. C．His desire to understand the world. D．His study in Michigan State University. 答案：B 2 3 1 4 推理判断题。根据第一段的“When describing his career，Meldal said he started out as an engineer but changed to chemistry ...”和第二段的“Meldal's experience may come as a surprise to students.They might believe they have to center their work and school lives in one field to be successful.”可知，学生们可能认为自己必须集中精力于一个领域才能获得成功，但Meldal却不是这样，他最初是工程师，后来才转学化学，由此可推测出，学生们感到惊讶的是Meldal最初的工作领域。故选B。 2 3 1 4 2．What kind of people can be sorted as “polymaths”？ A．People who are equipped with various interests. B．People who only concentrate on just one field. C．People who are committed lifelong to their career. D．People who are admired for established achievements. 答案：A 2 3 1 4 推理判断题。根据第三段的“They said that a large number of Nobel Prize winners can be described as‘polymaths'.”和第四段的“They decided that when students of winners go on to win Nobel Prizes，some of what they learned from their teachers is how to live a life with many interests.”可推知，可以被归类为“博学的人”的人是有着各种各样兴趣爱好的人。故选A。 2 3 1 4 3．What's the author's attitude towards the Root-Bernsteins' discovery? A．Subjective.　　　　 B．Doubtful. C．Objective. D．Opposed. 答案：C 2 3 1 4 观点态度题。根据第五段的“Having many interests，the Root-Bernsteins wrote，permits scientists to look for creative ways to solve problems.”和第六段的“The prize winners，the Root-Bernsteins said，transfer ‘skills，techniques and materials from one field to another.'”可知，本文作者只是转述Root-Bernstein夫妇的发现，因此作者对于Root-Bernstein夫妇的发现持客观态度，故选C。 2 3 1 4 4．Which of the following is a suitable title for the text? A．A Creative Scientist B．An Amazing Rise to Fame C．A Born Nobel Prize Winner D．A Secret to Winning Top Prize 答案：D 2 3 1 4 标题归纳题。通读全文，尤其是第三段可知，本文主要讲的是研究发现，许多诺贝尔奖获得者是博学多才的人，这可以说是获得诺贝尔奖的秘诀，因此本文最合适的标题是D项“A Secret to Winning Top Prize”，故选D。 2 3 1 4 Ⅳ.完形填空 Romero is an 84-year-old man.He owes his 1 to his pet dog，Palomo，who took 2 to him after he got lost in the desert for a week.
