[解析]
(1)D.逻辑关系题。分析句子结构可知,该空缺乏一个从句。D选项:When Einstein started to work in America(当爱因斯坦开始在美国工作时。)用When引导时间状语从句,表明下文someone asked him what he needed (有人问他需要什么。)事情发生的时间点,引出下文He said he needed a desk,some paper and pencil. (他说他需要一张桌子,一些纸和铅笔。)讲工作需要的工具。故选D项。
(2)A.标题归纳题。该空为小标题,起总结段落作用。由下文Many children wrote letters to ask him for help with their homework.One day,he wrote a letter to a young girl to tell her not to worry about her Maths homework because he thought Maths was difficult too. (许多孩子写信要求他帮他们做作业。一天,他写信给一个年轻女孩,告诉她不要担心她的数学作业,因为他认为数学也很难。)可知,下文讲最伟大的科学家爱因斯坦也认为数学也很难,说明他谦虚的品质,承接下文,A选项:Einstein was also very modest(爱因斯坦也很谦虚。)是最佳小标题。故选A项。
(3)G.细节理解题。由小标题Einstein considered time to be important (爱因斯坦认为时间很重要。)和上文He never wore socks because he thought putting on socks was a waste of time as people already wore shoes.He also thought remembering things found in books was not worth it. (他从不穿袜子,因为人们已经穿鞋子了,所以他认为穿袜子是浪费时间。他还认为,记住书本上的东西是不值得的。)可知,上文用具体事例讲明爱因斯坦不会做浪费时间的一些事,表明他注重时间的重要性,G选项:That's why he never remembered his own phone number(这就是为什么他从不记得自己的电话号码。)承接上文举出另一个爱因斯坦看重时间的例子,也讲明爱因斯坦为什么会这样做。故选G项。
(4)B.逻辑关系题。由小标题Einstein liked to joke too (爱因斯坦也喜欢开玩笑。)和In one exam,a student asked him why all the questions were the same as last year's.Einstein replied the questions were the same,but the answers were different. (在一次考试中,一个学生问爱因斯坦为什么所有的问题都和去年的一样。爱因斯坦回答的问题都一样,但答案不同。)可知,B选项:What a humorous person he is(他是一个多么幽默的人啊。)承接上文讲爱因斯坦拥有幽默感。故选B项。
(5)F.推理判断题。分析句子结构可知,该空缺乏一个从句。由上文When Einstein was a child,his teachers used to say he was not clever.However,Einstein kept working hard and surprised the world with his achievements. (爱因斯坦小时候,老师们常说他不聪明。然而,爱因斯坦一直在努力工作,他的成就令世界惊讶。)可知,爱因斯坦被老师说不聪明,也没有放弃努力工作,可见永远不要遇到问题就放弃、气馁,承接上文,F选项:If we ever feel like giving up when we have problems(如果我们遇到问题时想放弃。)用If引导条件状语从句,表明下文we should think of him (我们应该想想他。)事情发生的条件。故选F项。
