[解析]
(1)E.推理判断题。根据上文"The Free Dictionary defines a scientist as a person having professional knowledge on one or more sciences,especially natural science or physical science.It also defines a scientist as someone who uses scientific methods. (The Free Dictionary将科学家定义为拥有一门或多门科学专业知识的人,尤其是自然科学或物理科学。它还将科学家定义为使用科学方法的人)"并结合下文介绍的4科学家应该有的特征可知,空处句子应起到承上启下的作用,E项"让我们来看看优秀科学家的一些特征"符合题意,引出下文。故选E。
(2)F.联系上文题。根据上文"Scientists such as Thomas Edison and George Westinghouse discovered things mainly because they wanted to know how things work. (Thomas Edison和George Westinghouse等科学家发现事物主要是因为他们想知道事物是如何运作的)"和下文"then he/she never gets to the first stage of the scientific process.(那么他/她就永远无法进入科学过程的第一阶段)"可知,科学家最重要的特征就是要有好奇心,如果没有好奇新,那么就永远无法进入科学过程的第一阶段。F项"如果一个科学家没有提问的动力,甚至没有思考的动力"符合题意,与下文承接自然。故选F。
(3)C.联系上文题。根据上文"Becoming a scientist takes a long time.(成为一名科学家需要很长时间)"和下文"Even if you think you have received some education on science,you still have a lot of scientific research to do. (即使你认为你已经接受了一些科学教育,你仍然有很多科学研究要做)"可知,与其他职业相比,成为科学家花的时间相对较长,因此要更加有耐心。C项"很少有工作比这更耗时了"符合题意,选项中的this one指代上文becoming a scientist。故选C。
(4)D.推理判断题。根据本段小标题"Ethical qualities(道德品质)",和下文"a scientist must have a desire to improve people's life as well as the environment and living things,since they are all linked and they can affect one another in the long run. (科学家必须有改善人们的生活、环境和生物的渴望,因为它们都是相互联系的,从长远来看,它们可以相互影响)"可知,科学家要有道德上的高度,不仅仅要专研专业知识,还应该考虑用自己的知识造福环境、人类和社会等。D项"为了真正发现并运用知识为更大的利益服务"符合题意,与下文承接自然。故选D。
(5)A.段落标题题。空处为本段小标题。根据下文"An excellent scientist even takes notes of the smallest observation,keeping it in mind and recording it.He/She can work well alone or in groups,depending on what's needed.He/She also needs to communicate thoughts on paper and verbally.Networking skills connect him/her with colleagues working on similar projects where he/she may discover something new.(一位优秀的科学家甚至会记下最微小的观察结果,将其牢记在心并记录下来。根据需要,他/她可以单独或分组工作。他/她还需要在纸上和口头上交流想法。人际关系技巧将他/她与从事类似项目的同事联系起来,在这些项目中,他/她可能会发现一些新的东西)"可知,本段主要介绍科学家还应有好的工作习惯,这将有助他/她的工作和发现。A项"工作习惯"符合题意。故选A。
