　　In a telephone survey of more than 2，000 adults，21% said they believed the sun revolved (旋转)around the earth. An 71 7% did not know which revolved around 72. I have no doubt that 73 all of these people were 74 in school that the earth revolves around the sun; 75 may even have written it 76 at test. But they never 77 their incorrect mental models of planetary (行星的) 78 because their every day observations didn’t support 79 their teachers told them: People see the sun moving 80 the sky as morning turns to night，and the earth seems stationary (静止的) 81 that is happening. Students can learn the right answers 82 heart in class，and yet never combined them 83 their working models of the world. The objectively correct answer the professor accepts and the 84 personal understanding of the world can 85 side by side，each unaffected by the other.

　　Outside of class，the student continues to use the 86 model because it has always worked well 87 that circumstance. Unless professors address 88 errors in students’ personal models of the world，students are not 89 to replace them with the 90 one.

　　【答案解析】：

　　71.C四个答案都有“额外”的意思，但各有偏重。A重在表达“过量、超过正常的部分”;B是“在一类事物之外的额外部分”;D是“外加的”。因此只有C答案符合本题要求：“另外有7%的人不知道是谁绕着谁转。”

　　72.B如上题所述，句中已有which，要表达“不知谁绕着谁转”的意思，只能选B。

　　73.A本题考词汇。virtually：实际上地;remarkably：很明显地;ideally：理想地;preferably：更适宜地。从句意来看，只能选A。

　　74.C本句意：“实际上，这些人在学校都学过地球绕着太阳转的。”本句谓语用的是被动语态，故答案为C。

　　75.D本题考代词。承接上句，此处应为直接代替上句中所提到的人们，所以用they。

　　76.A此题考查固定搭配write on(记下，写下)。

　　77.B 由句中incorrect mental models一处可获得提示，“不正确的模型应该得到更正”，因此，此题选B答案。form：形成;believe：相信;think：认为。

　　78.C此句句意为：“但他们不肯改变脑海里错误的行星运动模式。”据意义判断，只有motion符合句意。选项中position和location都是表示静止位置的词，而行星是在不断运动中的，因此不能选。
