13．Below is a selection of 8unusual scientists who did research．
1．Wan tried to ride a rocket chair．You have to hand it to Wan Hu．Legend has it that when the Chinese official，Wan Hu，decided to visit the moon，he didn't ask one of his servants to sit in the hot seat．He settled himself into a wood chair fixed with 47rockets．When 47torch-bearing assistants lit the rockets，there was aloud sound and lots of smoke--but no more Wan Hu．There is，however，a crater named for Wan Hu on the far side of the moon．
2．Isaac Newton stuck a needle in his eye．Though best known for discovering the laws of gravitation，Newton also did pioneering research in optics．He experimented with prisms（棱镜），but that didn't reveal much about the eye's structure or how it senses color．To learn more，the unusual physicist took a type of needle known with a sharp tip and，he wrote，"put it between my eye and the bone as near to the backside of my eye as I could．"
3．Nicolae Minovici hanged himself．Nicolae Minovici performed a series of experiments in which he allowed himself to be choked by ropes．Though his feet reportedly never left the ground，he experienced a burning pain in his neck and signaled to be lowered．He had trouble swallowing for an entire month．
4．Franz Reichelt tested his parachute by jumping from the Eiffel Tower．On Feb 4，1912，an Austrian-borntailor named Franz Reichelt tested his"parachute（降落伞）suit"--an airman's suit designed to function as aparachute in the event of an emergency．Alas，the chute failed to open up，which contributed to his death．The event was recorded in still photos as well as in the grainy video below．
5．Evan O'Neill Kane took out his own appendix 阑尾）．Dr．Kane，a surgeon working in Pennsylvania in the early 20th Century，wanted to find out about appendix．On Feb.15，1921，he chose to perform the surgery himself and take out his appendix．But he calmly pushed them back in and kept working．
6．Werner Forssmann stuck a plastic tube in his own heart．In the early part of the last century，it was believed that inserting something into a beating heart would be deadly．Werner Forssmann thought other wise．So one day in 1929，he put a tube into his heart．Fortunately he survived the daring experiment but lost his job．But his fearlessness was rewarded when he won a Nobel Prize in 1956．
7．Frederick Hoelzel ate glass．And not just glass．During the 1920s and 1930s，University of Chicagoresearcher Frederick Hoelzel reportedly swallowed grain，glass，ball bearings，thread，wire，and other non-food items in order to show how long it would take the items to pass through his guts（肠子）．Despite his risky research，Hoelzel lived into old age．
=8．Barry Marshall drank bacteria-loaded soup．For many years doctors had only an unclear idea about the cause of stomach illness．So he decided to be his own pig，taking germs from an infected patient，mixing the min a solution，and drinking it．A few days later，after experiencing a period of throwing up and tiredness，he examined his own gut--and proved the link between the germs and illness．For his daring experiment he won a Nobel Prize in 2005．
46．Which of the following scientist's research certainly was recorded by video？D
A．Newton．
B．Minovici．
C．Hoelzel．
D．Reichelt．
47．Why did Werner Forssmann and Barry Marshall win the Nobel Prize？C
A．The two scientists were expert in surgery operations．
B．Both discovered the links between germs and disease．
C．They made significant breakthroughs in medical research through their brave experiments．
D．Each of them conducted the same experiment separately．
48．In which experiment did a scientist lose his life？A
A．Riding a rocket chair．
B．Eating glass．
C．Sticking a needle in his eye．
D．taking out his own appendix．
49．The greatest difference of the 8scientists from the majority of other scientists is thatB．
A．they devoted their time to scientific research
B．they would risk their lives for experiments
C．they were greatly enthusiastic about science
D．they made their great contributions to science．
分析 本文中六位科学家都是在实验过程中都冒了生命危险，这是他们与其他大多数的科学家最不同的地方．
解答 46：D 细节题．由第三个标题下，最后一句"The event was recorded in still photos as well as in the grainy video below．"可知，Reichelt 的研究被视频录下来了．其他科学家的研究均未提及被录像，故正确答案为D．
47：C 细节题．由第四个标题下最后一句"But his fearlessness was rewarded when he won a Nobel Prize in 1956．"和第六个标题下最后一句"For his daring experiment he won a Nobel Prize in 2005．"可知，Werner Forssmann 和 Barry Marshall 为科学大胆尝试，打破常规思维，在医疗研究中取得突破性进展而获得诺贝尔奖．其他选项均不是两人获得诺贝尔奖的原因．故正确答案为C．
48．A 细节理解题．根据文章内容"There is，however，a crater named for Wan Hu on the far side of the moon．"然而，在月球的另一边有一个叫Wan Hu的陨石坑，可知乘坐火箭死亡．故选A．
49：B 推断题．A项，"他们都把他们的时间奉献给科学研究"；B项，"他们为实验冒生命危险"；C项，"他们对科学有很大的热情"；D项，"他们对科学做出了很大的贡献"．根据文意，本文中六位科学家都是在实验过程中都冒了生命危险，这是他们与其他大多数的科学家最不同的地方．故正确答案为B．
点评 做这类题材阅读理解时要求考生对文章通读一遍，做题时结合原文和题目有针对性的找出相关语句进行仔细分析，结合选项选出正确答案．推理判断题也是要在抓住关键句子的基础上合理的分析才能得出正确答案，切忌胡乱猜测，一定要做到有理有据．
