单选题 One day two scientists were quarrelling about whose watch was better, the German one or the Japanese one Since they were scientists, they decided to do an experiment to test the watches. They went into their lab and filled a basin with water, put the watches in, waited for 20 minutes and took them out.
They could see there was something wrong with both watches. They observed them for several hours before speaking to each other. They both silently found that the German watch was losing 60 minutes and the Japanese one doubled that.
The scientist with the Japanese watch then slowly raised his head and said, "Both watch are out of work, but my watch is right more often than yours, so it's better." The scientist with the German watch went home without saying a word.

单选题 The two scientists were quarrelling at the beginning of the story, because ______.
【正确答案】 C
【答案解析】细节题。文章第一句即指出他们争论的内容是：whose watch was better(谁的手表更好)，故争论的原因当然就是他们都认为自己的手表更好，选[C]。
单选题 They did an experiment because they ______.
【正确答案】 A
【答案解析】细节题。文章第二句指出了他们做实验的目的：...to test the watches(检测手表)。由这一句与上一句的意思不难看出检测的目的就是要分出好坏，故选[A]。
单选题 After they did the experiments, they found ______.
【正确答案】 B
【答案解析】推理判断题。第二段说明了检测的结果。该段第一句首先指出两只手表都有了问题；而该段最后一句则表明它们的问题都是停摆、检测后时间不正确，因此答案是[B]。
单选题 After putting the Japanese watch in water, two scientists found ______.
【正确答案】 D
【答案解析】细节题。第二段最后一句指出：the German watch was losing 60 minutes and the Japanese one doubled that。考生关键是理解这一句中losing和doubled两个词的意思。前者指“失去”，用于时间时，指“走慢”；后者指“加倍”。德国手表慢了60分钟，日本手表加倍，那就是慢了120分钟，答案是[D]。
单选题 How about the German watch at last?
【正确答案】 D
【答案解析】推理判断题。文章最后一段描述了有日本手表的那位科学家强词夺理、宣称他的手表更好这一结果。而由第二段所指出的检测结果和这位科学家话语中的逻辑谬误可以推知应当是德国手表质量要好一些，而有德国手表的科学家一言不发只是觉得无法与有这种荒谬逻辑的人争辩，因此本题应选[D]。
