1、高中英语 Module 4 Great Scientists单元检测题 外研版必修4第一部分听力第二部分阅读理解(共两节，满分40分)第一节(共15小题；每小题2分，满分30分) 阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。AScientists at Royal Holloway, University of London and Queen Mary, University of London have discovered that bees learn to fly the shortest possible route between flowers eve
2、n if they discover the flowers in a different order. Bees are effectively solving the “traveling salesman problem”， and they are the first creatures found to do this. The traveling salesman must find the shortest route that allows him to visit all locations on his route. puters solve it by paring th
3、e length of all possible routes and choosing the shortest, and it can keep puters busy for days. However, bees solve it without puter assistance using a brain the size of grass seed. Dr. Nigel Raine, from the School of Biological Sciences at Royal Holloway explains，“Bees solve traveling salesman pro
4、blems every day. They visit flowers at multiple locations and because bees use lots of energy to fly, they find a route which keeps flying to a minimum.” The team used the puter to control artificial flowers to test whether bees would follow a route defined by the order in which they discovered the
5、flowers or if they would find the shortest route. After exploring the location of the flowers, bees quickly learned to fly the shortest route.As well as improving our understanding of how bees move around the landscape pollinating (授粉) crops and wild flowers，this research，which is due to be publishe
6、d in The American Naturalist, has other applications. Our lifestyle relies on networks such as traffic on the roads, information flow on the Web and business supply chains. By understanding how bees can solve their problems with such a tiny brain, we can improve our management of these everyday netw
7、orks without needing lots of puter time. Dr. Raine adds，“Despite their tiny brains，bees are capable of extraordinary feats of behavior. We need to understand how they can solve the traveling salesman problem without a puter.”语篇解读：英国的科学家发现，蜜蜂在花丛中飞行时，总是能够找到最近的路线，这个“销售员旅行难题”即使用电脑也需要好几天才能解决。21What would
8、 be the best title of the passage?ABees help salesmen travelBTiny brained bees solve a plex mathematical problemCHow bees discover the flowersDHow to solve the “traveling salesman problem”答案：B主旨大意题。“销售员旅行难题”用计算机也需要好几天才能解决，而蜜蜂毫不费力地就能在花丛中找到最近的飞行路线，故B项“具有微小大脑的蜜蜂解决复杂的数学难题”作为文章的标题最贴切。22We may infer from

10、_Aprovide further proof for the researchBtell us how bees can fly the shortest route between flowersCtell us how the research about bees flying route was conductedDexplain the importance of the research答案：D推理判断题。最后一段说明了蜜蜂飞行路线研究的意义和目的，是为了帮助我们在实际生活中更好地节省时间和精力。24It can be concluded from the passage tha
11、t _.Aall creatures are smarter than putersBthe research about bees flying route can be applied to many fieldsCour networks are more plex than bees onesDwith the help of the puter we can find out how bees can solve the “traveling salesman problem”答案：B 推理判断题。根据最后一段可以推断出对蜜蜂飞行路线的研究可以应用到其他领域中。BA high sch
12、ool in Hiroshima City has been the first to do something with DNA in the world. Its students have won praise not only for doing this research but also for presenting their findings to groups of expert scientists. The school is one of the Super Science High Schools allowed by the Ministry of Educatio

Here, students use the same type of hitech experimental laboratories as those found at universities. In these labs, they conduct experiments and research in new fields of study
14、 not found in textbooks. As part of this science course, the students, with the help of Hiroshima University, used a machine called sequencer(音序器)，and over the course of a year and a half they succeeded in decoding(翻译)the DNA. They then presented their results to academic groups. Achieving a world f
15、irst might sound very wonderful, but the process of decoding the DNA involved very hard work. The students were also responsible for maintaining the equipment, and they had to read difficult research papers and put in extra study beyond their regular schoolwork.“Researchers need to work hard. The wo
16、rk was tiring, but the students worked towards their ambitious goal of achieving a world first. They have a great sense of achievement, and the number of students who hope to bee biologists has increased，” said Taruma Akinori, who is in charge of the science course.In addition to the results being added to the scientific munity, the students research paper will be tr
