单选题 Students can learn mathematics only by exploring it on their own, with generous room for trial and error. For what matters in the long run is not acquiring particular computational skills (since without constant use skills rapidly fade), but knowing how to find and use suitable mathematical tools whenever they become necessary.
If the position expressed above is correct, then each of the following can be true EXCEPT:

【正确答案】 D
【答案解析】[解析] 本题段落中的论述强调了学生在学习数学时要发挥自己的主观能动性,而(D)则指出教师给出规则,学生死记硬背的学习方法,完全否定了段落中有关学生可以自学的灵活性的特点,因此(D)正确;(A)、(B)、(C)和(E)四个选项虽都不能从本题的段落中推出,但它们不与段落中的内容相抵触,同时也存在一定的可能性,所以(A)、(B)、(C)和(E)都是错误选项。
