托福閱讀細節(jié)題首先要找準“定位”

　　細節(jié)題是托?？荚嚠斨蓄}量最大的一種題型，主要是對原文的事實信息進行提問來考察學生的信息檢索能力和閱讀能力，并且所有的選項都會出現(xiàn)原文的信息來對考生進行干擾。例如：

　　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.

　　做細節(jié)題的第一步就是“定位”，要找到原文答案所在的區(qū)間。題干中問到“bluefin tunas”，我們回到原文，找到定位句：…A bluefin tuna in water of 7° C (45° F) can maintain a core temperature of over 25° C (77° F)…，即藍鰭金槍魚可以在低于自己體溫(25° C)的水溫(7° C)中生活，所以正確答案選擇第三個。而其它干擾選項在原文均有出現(xiàn)，但是并不屬于題干所問內(nèi)容。
