问题    For thousands of years, people have known that the best way to understand a concept is to explain it to someone else. "While we teach, we learn," said Roman philosopher Seneca. Now scientists are bringing this ancient wisdom up-to-date. They’ re documenting why teaching is such a fruitful way to learn, and designing innovative ways for young people to engage in instruction.
   Researchers have found that students who sign up to tutor others work harder to understand the material, recall it more accurately and apply it more effectively. Student teachers score higher on tests than pupils who’ re learning only for their own sake. But how can children, still learning themselves, teach others? One answer; They can tutor younger kids. Some studies have found that first-born children are more intelligent than their later-born siblings (兄弟姐妹). This suggests their higher IQs result from the time they spend teaching their siblings. Now educators are experimenting with ways to apply this model to academic subjects. They engage college undergraduates to teach computer science to high school students, who in turn instruct middle school students on the topic.
   But the most cutting-edge tool under development is the " teachable agent" —a computerized character who learns, tries, makes mistakes and asks questions just like a real-world pupil. Computer scientists have created an animated (动画的) figure called Betty’s Brain, who has been "taught" about environmental science by hundreds of middle school students. Student teachers are motivated to help Betty master certain materials. While preparing to teach, they organize their knowledge and improve their own understanding. And as they explain the information to it, they identify problems in their own thinking.
   Feedback from the teachable agents further enhances the tutors’ learning. The agents’ questions compel student tutors to think and explain the materials in different ways, and watching the agent solve problems allows them to see their knowledge put into action.
   Above all, it’ s the emotions one experiences in teaching that facilitate learning. Student tutors feel upset when their teachable agents fail, but happy when these virtual pupils succeed as they derive pride and satisfaction from someone else’ s accomplishment.
How does teaching others benefit student tutors?
选项 A、It makes them aware of what they are strong at.
B、It motivates them to try novel ways of teaching.
C、It helps them learn their academic subjects better.
D、It enables them to better understand their teachers.
答案C
解析 细节题。原文第二段第一、二句话指出，研究人员发现，参加辅导他人活动的学生会更努力地去理解材料，更准确地记起知识并更能有效地应用它们。在考试中，学生教师的分数比那些只自己学习的学生要高。原文第三段倒数第二句话指出，在准备教学的过程中，学生教师将自己脑海中的知识系统化了，并且提高了自己的理解能力。由此可知，教授别人知识，可以帮助学生更好地学习他们的学科知识，故答案为C。A、B、D三项原文均未提及，故排除。
