　　托福閱讀推斷題如何用因果關系來解題?

　　Paragraph 4: So, in another set of experiments, Kramer putidentical food boxes around the cage, with food in only one of the boxes. Theboxes were stationary, and the one containing food was always at the same pointof the compass. However, its position with respect to the surroundings could bechanged by revolving either the inner cage containing the birds or the outerwalls, which served as the background. As long as the birds could see the Sun,no matter how their surroundings were altered, they went directly to thecorrect food box. Whether the box appeared in front of the right wall or theleft wall, they showed no signs of confusion. On overcast days, however, thebirds were disoriented and had trouble locating their food box.

　　Which of the following can be inferred from paragraph 4 aboutKramer’s reason for filling one food box and leaving the rest empty?

　　A He believed the birds would eat food from only one box.

　　B He wanted to see whether the Sun alone controlled the birds'ability to navigate toward the box with food.

　　C He thought that if all the boxes contained food, this woulddistract the birds from following their migratory route.

　　D He needed to test whether the birds preferred having the food atany particular point of the compass.

　　首先，我們來明確一下推斷的定義(infer, imply, indicate)，縱使它是推斷題，也不是意味著這題是主觀臆斷，臆想或是聯(lián)想得出的。這道題也是要通過提取題干中的關鍵詞到文章中的明確位置，然后文中沒有平鋪直敘地告訴你答案，需要我們根據(jù)一些線索找到答案。

　　接下來我們來看一下這道題，題干中出現(xiàn)Kramer, filling one food box andleaving the rest empty定位在第四段第一句：with food in only one of the boxes，而解開這道題的重點就在于：reason。我們看到第一句話一開始說到，so, in another set of experiments，很明顯，答案并不在這一段，而是上一段的最后。所以答案是B。
