写作导航 In a word，it is the trivial things in daily life that count.Just as the famous saving goes，do not think any virtue trivial，and so neglect it；do not think any vice trivial，and so practice it. 基础再现 考点整合 语法专题 写作导航 题型突破 栏目链接 推理判断型阅读理解(2) 题型突破 一、推断文中人物的观点、情感、品性 题型突破 题干有What do we know about sb. in the text？/How did sb. feel about...？/His attitude towards...is that...等标志语句。答题时要准确把握文段的相关信息来推断文中人物对所涉及的人物或事情的观点、态度、情感、性格、品质等。 二、推断文章的续写内容 题型突破 题干有In the next part，the author would most probably discuss.../What is most likely to be discussed in the paragraph that follows？等标志语句。答题时可根据语篇内容、写作思路与文章结构来预测作者接着要写什么。最后一段的最后一句话非常重要。 三、推断结论、提炼观点 题型突破 题干有What can be inferred from Paragraph？/We can conclude from the text that...等标志语句。答题时可根据某(几)句话或某段或全篇提炼出一种观点或得出总结性的结论。 专项训练 题型突破 阅读理解练习 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. 题型突破 “To provide enough power，we need certain methods with high energy density(密度)”，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/nanoelectromechanreal systems (M/NEMS). Although nuclear batteries can cause concerns，Kwon said they are safe. 题型突破 “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(晶体结构) 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. 题型突破 1．The text is most probably a ________． A．science news report B．book review C．newspaper ad D．science fiction story 2．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. 题型突破 3．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 4．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 题型突破 5．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 题型突破 1．解析：推理文体题。本文讲述了Kwon的原子能电池的有关情况，文章体裁应属于科普文章，所以A项正确。 答案：A 2．解析：事实细节题。根据第三段的叙述可知Kwon在研究一种原子能电池，故选C。 答案：C 3．解析：推断作者写作手法的目的。根据文章第四段可知Kwon举例的目的是为了说明原子能电池是安全的，所以B项正确。 答案：B 题型突破 4．解析：事实细节题。根据倒数第二段“By using a liquid semiconductor, we believe we can minimize that problem.”可知选D。 答案：D 5．解析：事实细节题。根据最后一段“Kwon said that battery could be thinner than the thickness of human hair.”可知选C。 答案：C 题型突破 考点整合 |
