    In a telephone survey of more than 2,000 adults, 21% said they believed the sun revolved around the earth. An【C1】______7% did not know which revolved around which. I have no doubt that 【C2】______ all of these people were taught in school that the earth revolves around the sun; they may even have written it on a test. But they never【C3】______ their incorrect mental models of planetary【C4】______ because their everyday observations didn’t support what their teachers told them: People see the sun moving across the sky as morning turns to night, and the earth seems stationary【C5】______ that is happening.
    Students can learn the right answers by heart in class, and yet never【C6】______ them with their working models of the world. The objectively correct answer the professor accepts and the student’s personal understanding of the world can【C7】______ side by side, each unaffected by the other.
    Outside of class, the student continues to use the【C8】______ model because it has always worked well in that circumstance. Unless professors address specific【C9】______ in students’ personal models of the world, students are not【C10】______ to replace them with the correct ones.

选项

答案M

解析 空格前为形容词planetary,因此空格处应填入名词。上文提到的the sun revolved around the earth、which revolved around which及下文提到的the sun moving across the sky、the earth seems stationary都是对行星运动的描述,词库中的名词motion“运动”填入后符合语境,表示“行星运转”。operation意为“操作”,通常是指机器的操作,可排除。
