托福阅读考题中的每篇文章题量基本在13-14题，而在这13-14题当中，细节题又会占据到3-6题，可见其在托福阅读考题当中所占的比重之大。既然这类题目出题频率如此之高，我们来浅谈一下托福阅读解题技巧，以及同学们平时做题时易犯的错误。
做细节题的第一步是审题目，找到题目当中的关键信息，以下题为例：
According to paragraph 2, camels were important because they…
读完题目，大多数同学都能迅速得出关键信息，即camels和important。但是同学们一定要注意，此题还有一个关键信息就是because，题目问的是camels很important的原因！既然已经判断出了题目的关键信息，第二步就是用关键信息回原文定位，找到关键信息所在的那一句或者那几句定位句，精读定位句。读完定位句之后，最后一步才是去读四个选项，选择正确答案。
以上题为例，题目问的非常明确，定位起来也不易错。但是有些题目的定位就没有这么容易了，以下题为例：
Paragraph 3 Climatic changes at the end of the glacial period 13,000 years ago have been proposed to account for the emergence of farming. The temperature increased dramatically in a short period of time (years rather than centuries), allowing for a growth of the hunting-gathering population due to the abundance of resources. There were, however, fluctuations in the climatic conditions, with the consequences that wet conditions were followed by dry ones, so that the availability of plants and animals oscillated brusquely.
According to paragraph 3，the abundance of resources fluctuated sharply after the end of the glacial period because…
》locally abundant resources were quickly exhausted by hunter-gatherers
》the temperature became much higher in some areas over others
》different types of plants and animals became available as the climate changed
》the amount of rainfall varied radically from one period to the next
有的同学读完题目，觉得该题的关键信息是the abundance of resources的原因，然后用此信息直接去原文定位，找到这么一句话The temperature increased dramatically in a short period of time (years rather than centuries), allowing for a growth of the hunting-gathering population due to the abundance of resources. 如果拿这句话做定位句是不可能选出正确选项的，因为定位定错了。
我们再读一遍题目，题目问的其实不是the abundance of resources的原因，问的是the abundance of resources fluctuated sharply（丰富资源急剧波动）的原因。由此回原文定位，会找到这么一句话There were, however, fluctuations in the climatic conditions, with the consequences that wet conditions were followed by dry ones, so that the availability of plants and animals oscillated brusquely. 精读完此句，会发现the availability of plants and animals oscillated brusquely（植物及动物急剧震荡）的真正原因是气候急剧波动导致湿季跟着干季。也就是第四个选项的意思the amount of rainfall varied radically from one period to the next，从而确定第四个选项为正确选项。
总结一下，细节题的关键是要找出题目中的关键信息，再用关键信息进行定位。请同学们一定要读懂题目再回原文定位！
