5 阅读理解。 Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient. "To provide enough power, we need certain methods with high energy density",said Jae Kwon, assistant professor of electrical and computer engineering at MU. "The radioisotope (放射性同位素) battery can provide power density that is much higher than chemical batteries." Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe. "People hear the word "nuclear" and think of something very dangerous," he said, "However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems." His new idea is not only in the battery"s size, but also in its semiconductor(半导体). Kwon"s battery uses a liquid semiconductor rather than a solid semiconductor. "The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor," Kwon said, "By using a liquid semiconductor, we believe we can minimize that problem." Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery"s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair. 1. Which of the following is true of Jae Kwon? A. He teaches chemistry at MU. B. He developed a chemical battery. C. He is working on a nuclear energy source. D. He made a breakthrough in computer engineering. 2. Jae Kwon gave examples in Paragraph 4_________. A. to show chemical batteries are widely applied. B. to introduce nuclear batteries can be safely used. C. to describe a nuclear-powered system. D. to introduce various energy sources. 3. Liquid semiconductor is used to _________. A. get rid of the radioactive waste B. test the power of nuclear batteries. C. decrease the size of nuclear batteries D. reduce the damage to lattice structure. 4. According to Jae Kwon, his nuclear battery _______. A. uses a solid semiconductor B. will soon replace the present ones. C. could be extremely thin D. has passed the final test. 5. The text is most probably a ________. A. science news report B. book review C. newspaper ad D. science fiction story

7 阅读下面短文,按照句子结构的语法性和上下文连贯的要求,在空格处填人一个适当的词或使用括号中词语的正确形式填空。 This happened in a third-grade classroom. Jim sat 1 his desk and all of a sudden, there was a puddle(一滩水) between his feet and the front of his trousers was wet. He felt his heart was going to stop. He knew 2 would happen when his classmates found out. He looked up and there came the teacher with 3 look in her eyes that said he 4 (discover). As the teacher was walking towards 5 , a classmate named Susie was carrying a goldfish bowl full of water to her desk. Suddenly, Susie tripped (绊倒) and, 6 (strange), dumped the whole bowl of water in Jim"s lap. He pretended to be angry, but all the while he was saying deep in his heart, "Thank you!" Jim became the object of sympathy instead of ridicule (嘲笑). The teacher brought him gym shorts to put on. All the others crawled(爬) on their hands and knees, 7 (clean) up around his desk. But 8 life would have it, the ridicule that should have been his had been transferred (转移) to Susie. She tried to help, 9 they told her to leave the room 10 school was over, Jim walked over to Susie and whispered, "You did that on purpose, didn"t you?" Susie whispered back, "I wet my trousers once, too!"
