A teacher stood in front of his history class of twenty students just before handing out(分发) the final exam. His students sat quietly and waited for him to speak.
“It’s been a pleasure teaching you this term,” he said. “You’ve all worked very hard, so I have a pleasant surprise for you. Everyone who chooses not to take the final exam will get a ‘B’ for the course.”
Most of the students jumped out of their seats. They thanked the teacher happily, and walked out of the classroom. Only a few students stayed. The teacher looked at them. “This is your last chance,” he said. “Does anyone else want to leave?” All the students there stayed in their seats and took out their pencils.
The teacher smiled. “Congratulations (祝贺),” he said. “I’m glad to see you believe in yourselves. You all get ‘A’ s.”

解析：这篇短文主要讲述了一位历史老师在期末考试的时候，利用一个有趣的试验，检验了学生是否对自己有信心的故事。
【小题1】推理判断题。根据短文第一段A teacher stood in front of his history class of twenty students just before handing out(分发) the final exam。the final exam期末考试，故选C。
【小题2】推理判断题。根据第二段老师说的话和第三段开头，老师说不参加考试的人可以获得B，大部分学生跳起来感谢了老师，就离开了教师。故选B.
【小题3】推理判断题。根据短文描述，这些同学没有离开教室，是想参加考试。并不想只是得个B。故选A.
【小题4】细节理解题。根据最后一段I’m glad to see you believe in yourselves. You all get ‘A’ s描述，我很高兴你们对自己的自信，你们将都得A，可知由于剩余学生的自信老师给了A。故选C。
【小题5】词义猜测题。根据Only a few students stayed. The teacher looked at them.描述，仅有几个学生呆在那，老师看着他们，可知后文中的them指代前面留下的学生。故选A.
