参考答案

正确答案：B
解析：题目问：在第四段的“as the fit takes them”是指什么?第四段第一句“Those who believe that theyneed only work and study as the fit takes them have a mistaken belief either in their own talent or in thevalue of freedom”．通过这句话可知，那些相信心情好时才能工作和学习的人，对于他们自己的才干和“自由”的价值都有错误的理解。在这里，as the fit takes them是指when they are in the mood。所以，答案是B。
