读书贵有可疑，可贵之处，就是独立思考，敢于大胆探索和追求。但是，提倡读书有疑、并不是脱离客观实际，并不是违背科学的胡猜乱疑，要疑得正确，疑得有长进，还必须善于疑。否则，当疑不疑，不当疑又乱疑，那不但得不到任何长进，相反还会把思想引上邪路，这绝不是我们应取的治学态度。最能准确概括这段基本意思的是( )

A．读书的可贵之处在于独立思考

B．读书的可贵之处在于不能违背科学的胡乱猜忌

C．当疑不疑，不当疑又乱疑会把思想引上邪路

D．应采取严谨的治学态度，不要轻易生疑

A teacher stood in front of his history class of twenty students just before handing out 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.
