OG,P116，Q10
Paragraph 9: The muscles of these fishes and the mechanism that maintains a warm body temperature are also highly efficient. A bluefin tuna in water of 7°C (45°F) can maintain a core temperature of over 25°C (77°F). This warm body temperature may help not only the muscles to work better, but also the brain and the eyes. The billfishes have gone one step further. They have evolved special "heaters" of modified muscle tissue that warm the eyes and brain, maintaining peak performance of these critical organs.
10. According to paragraph 9, which of the following is true of bluefin tunas?
○Their eyes and brain are more efficient than those of any other fish.
○Their body temperature can change greatly depending on the water temperature.
○They can swim in waters that are much colder than their own bodies.
○They have special muscle tissue that warms their eyes and brain.
学生答案：D
在做这道细节题的时候，学生先把第九段通读了一遍，然后凭记忆觉得选项D在原文最后一句话出现过，所以错选了D。
解决方案
1). 帮助学生建立'先看问题，再读原文"的思维模式。
详解：托福阅读大多数细节题只考察对应段落中的一句或两句话的意思，所以先在问题中锁定定位词会比较节省时间，并且有助于提高正确率。徐璇由于习惯了国内英语考试的套路，所以忽略了这一步骤，通过几道简单的例题，帮助她训练找定位词的能力。
2). 详细解释错误答案的特征。
详解：徐璇偏向于用正向的思维来解题，而实际阅读考试中，很多错误选项原文未提及，或者提及但与原文矛盾，了解错误选项的特征可以帮助考试提高正确率，并在练习与考试中自查错误，稳定考试心态。

利用问题中的"bluefin tunas"去原文定位，得到"A bluefin tuna in water of 7°C (45°F) can maintain a core temperature of over 25°C (77°F)."
(意为：一条蓝鳍金枪鱼在7摄氏度的水里可以维持超过25摄氏度的核心温度)，选项C为正确答案。A项为虚假比较，原文并没有把蓝鳍金枪鱼和其他鱼种做比较;B选项与原文矛盾;D选项定位错误，原文最后一句话主语为"billfishes"， 已不是定位词"蓝鳍金枪鱼"。
