15、e depression and illness, said Dr. William Fry, a psychiatry professor at Stanford University Medical Center in California. But theres a growing realization of just how powerful pleasure is.For example, research shows that smiling and laughing can actually strengthen your immune system, reduce stres

16、s and physical pain, and even help cancer patients. One research project at Loam Linda University showed these beneficial effects of laughter on the body. In the study, ten medical students were hooked up to several machines and spent an hour watching a funny videotape of a man smashing watermelons

17、with a hammer.Researchers were not trying to prove that smashing watermelons is a funny thing to do. They already knew that the volunteers would probably howl with laughter. What the researchers wanted to find out was how grinning, chuckling, and howling affected the volunteers as they watched the v

18、ideo.The researchers were delighted to discover that small but important changes were taking place in the volunteers bloodstream as they giggled or roared with laughter. Their blood showed increased production of white blood cells (the blood cells that defend us against infection and disease). At th

19、e same time, a decrease was noticed in the levels of chemicals that stop the immune system from working properly.Studies such as this seem to show that you should laugh, chortle, and howl as much as possible! You will increase your chances of living a long, healthy life, Thats what one researcher me

20、ans when he says, He who laughs, lasts. For years weve thought that laughter and other forms of pleasure were good for you. Now its a physiological reality.Text 1 译文：越来越多的科学家发现，任何乐事带来的不仅仅是乐趣。快乐和幽默可以使我们增寿、抵御疾病和治疗药物成瘾。“科学家们一直以来忽略了快乐和幽默的作用，而重视研究负面的东西，比如,失落和疾病。”威廉弗莱博士这样说到，“但是也越来越多地认识到快乐的强大力量。”比如，一项研究表明微

21、笑和大笑实际上可以提高你的免疫系统能力、减轻压力和病痛，甚至还可以帮助癌症患者。罗姆林达大学的一项研究项目证明了这些在人身体上笑的有益作用。在这项研究中，十名和几台机器连接的医科学生要花一个小时观看一部一个人用锤子砸西瓜的有趣录像。研究者们并非是要了解砸烂西瓜是件趣事。他们知道这些志愿者们很可能会笑得大叫出来。他们最终想要了解的是咧嘴笑、咯咯地笑和大笑出声是如何影响这些观看录像的学生。研究者们高兴地发现了当这些学生咯咯笑或狂笑时在他们的血流里发生了一些小但是很重要的变化。他们的血液产生了更多的白血细胞（这种细胞帮助我们抵御感染和疾病）。同时，阻止免疫系统正常运行的化学物质含量减少了。这样的研究

22、表明了你应该尽可能地大笑、咯咯地笑或狂笑出声！你长寿、健康的机率会大大增加。这也是一位研究者想要说的：“笑的人才会持久。很多年来我们都认为笑或其他表示快乐的形式都会对你有好处。现在，这是一个生理上的现实了。”46. According to the text pleasure and humor might _.A. cure cancer B. cure infectious diseases C. help people concentrate D. help people quit smoking答案：D第一段中提到pleasure and humor might help us liv

23、e longer, fight off illness, and cure drug addiction，但文章并没有提到能够治疗癌症、医治传染病和使人精力集中。所以A, B, C 答案都不对。Smoking可以认为是一种drug addiction,所以答案应是 D。47. In Dr. William Frys opinion scientists _.A. have paid enough attention to the effect of laughter B. have neglected depression and illnessC. have preferred pleasu

24、re and humor to depression and illnessD. have realized the importance of pleasure in peoples lives答案：D第一段中提到Dr. William Fry讲But theres a growing realization of just how powerful pleasure is。文章也提到科学家忽略了pleasure的作用，而重视研究depression和illness。所以A、B和C肯定是错误的。48. Laughter helps to fight off illness because _

25、.A. it increases blood flow in human body B. it helps the production of blood cellsC. it can strengthen the immune system and reduces physical pain D. it can reduce chemicals in human blood答案：C这一题是逻辑推理题。Laughter能够有助于抵御疾病，其原因必须是直接原因。抵御疾病的直接原因应是免疫系统能力的提高和减轻病痛，所以答案应是C。49. In the text the researchers we

26、re trying to find out _.A. how the ten students would laugh B. why the ten students laughedC. how laugh would affect the students D. why smashing watermelons was funny答案：C第三段中提到科学家实验的目的并非是要了解砸烂西瓜是否有趣，他们最终是要了解笑是如何影响这些接受实验的学生。50. The best title for the text would be _.A. Laughter-A Powerful Medicine B

27、. Laughter-An Illness KillerC. Laugh and Live Long D. A Psychological Reality答案：A本文的核心是讲笑能帮助抵御疾病。所以“有效的药物”来形容笑是比较合适的。而killer（杀手）一词有些言过其词了，C和D离题材又太远了。Test 2Thomas Alva Edison, the American inventor, was born in 1847.
