6．Charlie studied in a famous collage for four years．He studied hard and did well in all his subjects．He hoped to become a good teacher．This year he left school and began to work in a middle school．He likes his students and is strict with them．He does his best to make his classes lively and interesting．One day he carefully explained a chemical reaction（化学反应）to students of Grade Two in the chemistry lab．
"Be careful，everyone，"he said loudly．"Before I make the experiment，there're twenty-five atoms of carbon（碳原子），but after I finish it，there're twenty-four atoms of carbon left!"
He then watched the classroom and hoped his students would go on explaining it．But the young men looked at each other and nobody answered him．He had to ask，"What happens？""What makes the atom lost？"
The classroom was very quiet and none of the students looked at their teacher．
"Who can tell us where it had gone？"
Suddenly a soft voice came from the back row，"we did not see anybody leave the classroom!"

分析 查利在一个著名的大学学习了四年，他努力学习，各门功课都很好．他希望成为一个好老师，今年他大学毕业，开始在一所中学工作．他喜欢他的学生，并对他们要求严格．他尽力使他的课生动有趣．
有一天，他在化学实验室给二年级的学生们仔细地解释化学反应．
"大家，仔细点，"他大声说．"在我做实验之前，有25个碳原子，但当我完成时，只剩下24个碳原子！
他停下来看同学们，希望他的学生们继续解释，但年轻人看着对方，没有人回答他．他不得不问："发生了什么？""什么使原子失去了？
教室里很安静，没有一个学生看着他们的老师．
"谁能告诉我们它去了哪里？"
突然一个柔和的声音从后排传来，"我们没有看见有人离开教室！"
解答 25．C．细节理解题，根据题干"查利开始在中学工作，因为…"，阅读短文第一段可以找到相关信息"He hoped to become a good teacher．This year he left the college and began to work in a middle school．"由此可以推断出：查利开始在中学工作，因为他希望成为一名好老师．故选C．
26．A．推理判断题．根据第一段He hoped to become a good teacher．This year he left school and began to work in a middle school．He likes his students and is strict with them．He does his best to make his classes lively and interesting可知查利希望所有的学生都能理解他，所以他尽最大努力使他的课生动有趣；故选A．
27．B．细节理解题，根据题干"学生们没有回答查利的问题，因为…"阅读短文第四段"But the young men looked at each other and nobody answered him．"和第五段"The classroom was very quiet and none of the students looked at their teacher．"结合下文一个学生有趣的回答，可知学生们没有理解他所讲的知识，故选B．
28．A．推理判断题．根据短文中老师的提问"，"What happens？""What makes the atom lost？"查利是想问少了一个原子到哪里去了，为什么？这是一个化学反应．"后排的那个学生听到老师提问"Who can tell us where it had gone？"理解成谁离开了教室，所以他回答成"我们没有看见有人离开教室！"，这说明他没有认真看老师做实验，也说明老师的课失败了．故选：A．
点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
