托福阅读考试时间高效利用方法

一.托福阅读做题技巧之利用关键词定位

考生在做题过程中，要熟练掌握根据关键词进行定位的技巧。这一技巧可以帮助大家加快解题速度，提高正确率。因为大部分托福阅读题目考查的是考生对文章细节的理解，答案基本上都能在文章中找到。拿到一个题目，我们先找题干中可以用来定位的关键词，比如专有名词、数字、符号等，然后根据关键词回到原文进行定位。有时候文章中不一定会出现和关键词一模一样的词，但很可能是关键词的同义替换词。

二.托福阅读做题技巧之排除法

托福阅读中有些题目枝干信息太多，但都是干扰项，如果逐字阅读的话会很浪费时间。正确的做法应该是从选项中挖掘一下方向，如果有几项答案自相矛盾或者意思明显相反，就可以直接排除，然后再对模糊选项进行确认，这时候再回到正文中细读相关信息就会很省力。一般情况下，排除法是比较容易培养的套路，考生要善于使用这一技巧提高答题速度。

三.托福阅读做题技巧之掌握句子变化

问句中所含信息与文章中相应句子中的信息在顺序上有时可能出现不同，甚至前后完全倒置。这种情况可能会导致迷失答题的方向。还应注意到文章中有关问句的信息并非全都能在每个句子中找到，甚至在关键词及短语之间存在一些不相关的信息，这些都会是寻找答案过程中的困难。

四.托福阅读做题技巧之找同义词

在托福阅读考试中，能否准确找出正确答案很大程度上取决于能否辩认出同义词、近义词、相关词及不同形式的短语。1.词形完全相同; 2.词义相同，即同义词;3.词义相近，但并非同义;4.词义相关。上述四种词汇/短语表达方式中，第一种当然容易辩认，第二种同义词也相对不难，但第三种与第四种形式则不易辩认，所以要在阅读过程中多加比较练习。如能攻破这一关，则一定能够取得好的考试成绩。

托福阅读真题原题+题目

The smooth operation of an ant colony depends on ten to twenty different signals, most of which are pheromones (chemical signals triggering behavioral responses). It is estimated that red fire ants employ at least twelve different chemical signals. The simplest of these is the carbon dioxide from the respiration of an ant cluster, a chemical that acts as a pheromone to promote aggregation. Workers move toward a source of carbon dioxide, resulting in solitary ants moving to join a group. At the other extreme, the most complex of the fire ants' signals is probably colony odor, by which the workers of a particular colony or nest identify another worker as local or foreign. Each ant nest has its own odor as a result of its location, history, and local food supply. The resident ants pick up this odor on their bodies, so that ants of the same species, but from different nests, have different colony odors. This allows ants to identify intruders and maintain colony integrity.

Fire ants also make use of an alarm pheromone to alert workers to an emergency, and their scouts lay down a trail pheromone as a guide during mass migrations. A fire ant queen emits a chemical signal that identifies her to the colony's workers. They respond by scurrying to gather around her. The decomposing corpse of a dead ant also generates a signal, to which workers respond by eliminating the corpse from the nest.

Ants provide examples of both public (accessible to other species) and private messages. One of their most important private messages concerns food, for a food source is worth keeping secret. Each species marks its trails with signals that are meaningless to others, so that an ant crossing a trail left by another ant species typically notices nothing. On the other hand, a secret signal to mark a dead body is unnecessary. Many kinds of ants perceive a natural decomposition product of dead insects as a signal to remove a corpse. If an outsider recognizes this message and moves the body, no harm is done.
