做过真题的同学一定会都知道，推断题应该是我们阅读十大题型中最难的题型之一了。一看到这个命名，很多同学都会疑虑，这个题型难道是考智力吗？需要我们去做推理吗？其实不用，托福作为一项语言考试，所有答案都是原文中可得的，不用真推。

    推断题题干中通常会出现infer/imply/indicate/suggest等标识词，这些词也足以说明，答案只是没有在原文中直接体现，但一定在原文中找得到支撑点的。解决这个题型，我们惯用的是排除法，当然也会有一些常考的推断思路，下面给大家介绍最常见的一种——语意推断。

    举个栗子：

    In Southwest France in the 1940’s, playing children discovered Lascaux Grotto, a series of narrow cave chambers that contain huge prehistoric paintings of animals. Many of these beasts are as large as 16 feet (almost 5 meters). Some follow each other in solemn parades, but others swirl about, sideways and upside down. The animals are bulls, wild horses, reindeer, bison, and mammoths outlined with charcoal and painted mostly in reds, yellow, and browns. Scientific analysis reveals that the colors were derived from ocher and other iron oxides ground into a fine powder. Methods of applying color varied: some colors were brushed or smeared on rock surfaces and others were blown or sprayed. It is possible that tubes made from animal bones were used for spraying because hollow bones, some stained with pigment, have been found nearby.

    What are the bones found in the Lascaux caves believed to indicate?

    ○Wild animals sometimes lived in the cave chambers.

    ○Artists painted pictures on both walls and bones.

    ○Artists ground them into a fine powder to make paint.

    ○Artists developed special techniques for painting the walls. 

解题思路：

    题目问，在Lascaux caves发现的bones可以暗示什么？我们拿题干中bones定位，可得答案相关句应该最后一句话。意思是：这些骨头是拿来做管子的，管子是用来spay的，因为有些空的管子，上面还粘着颜料，在边上被发现了。接着我们看选项做一一排除。选项A、B的意思显然毫无相关性，如果有同学想选，那真的是自己纯推了。细心的同学会发现选项C似乎在原文中有原句，倒数第三句中提到Scientific analysis reveals that the colors were derived from ocher and other iron oxides ground into a fine powder.但是这里被研磨的是ocher and other iron oxides，选项中的ground them into a fine powder，them指的是bones，所以排除选项C。选项D是画家用的一种特殊的作画方式，虽没有直接说，但最后一句话是能支撑这个意思的。结合倒数第二句就更好理解了，Methods of applying color varied，其中包含spay，骨头做成的管子也是用来spay，所以也是一种上色的方式。选项D正确。

    这就是我们在做语意推断的题时所用的思路，先排除无依据的、错的，剩下来的在原文中找到对应的支撑点。你学会了吗？
