  Mathematics instructors assigned some of the students enrolled in a calculus to participate in a small student-led group-study workshop. Since workshop participants achieved a significantly higher average course grade than those who did not participate,the mathematics department attributes this superior performance in calculus to workshop participation.

  The mathematics department’s reasoning, as described above, assumes which of the following?

  A:Calculus is a difficult subject for instructors to teach to large groups of students.

  B:The students who participated in the workshop were initially neither much better prepared nor much more highly motivated than the students who did not participate in the workshop.

  C:The time spent in the calculus workshop did not have a significantly adverse effect on the participants’ performance in their other courses.

  D:Few of the students who participated in she workshop planned to enroll in any mathematics courses more advanced than calculus.

  E:The student who participated in the workshop received much more individualized attention from the calculus instructor than did the students who did not participate in the workshop.

  最佳解析:

  题推论为:“因为参加学习组的学生比未参加学习组的学生得分高,所以参加学习组起到了作用。”本题从双方学生在微积分方面不同的表现得出结论:参加学习组有用。结论是对原因中事实的说明,而该推理要想成立,必须基于的假设为“没有其它原因来解释上面的现象了”。(B)选项指出这些参加学习组的学生既没有很好地准备,也不是更积极学习的学生,达到了上面的目的。因为如果这些学生更好准备,或者更积极学习,也能够说明为什么这些参加学习组的学生表现好,而对参加学习组起到作用的结论提出了质疑。所以(B)is correct。(A)(C)(D)均与该推理无关。读者仔细考虑(E)选项,它能够起什么作用?为什么?在后面对演绎另一类题型的分析中,本书会重点剖析类似于(E)和的选项所起的作用。

  答案:B
