阅读理解练习一Directions: Read the following three texts. Answer the questions on each text by choosing A, B, C or D. Text 1 　　An increasing number of scientists have found that anything that gives you pleasure may be more than just fun. Pleasure and humor might help us live longer, fight off illness, and cure drug addiction. "Science has generally neglected pleasure and humor to concentrate on negative things like depression and illness," said Dr. William Fry, a psychiatry professor at Stanford University Medical Center in California. "But there's a growing realization of just how powerful pleasure is."　　For example, research shows that smiling and laughing can actually strengthen your immune system, reduce stress 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 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 video.　　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 the 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, That's what one researcher means when he says, "He who laughs, lasts. For years we've thought that laughter and other forms of pleasure were good for you. Now it's 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。

Even as a child , he was always curious and always trying to invent new things. He was not a good student in school, but by the time he was a teenager, he had already had several jobs: store owner, telegraph operator, and inventor. He also had done lots of chemistry experiments on his own.　　However, what Edison really wanted to do was research. He established his first laboratory in Menlo Park, New Jersey, and later he set up another one in West Orange, New Jersey. In these laboratories, he enjoyed trying to come up。
