托福阅读与四六级阅读难易度差距分析
对于很多备考托福的学生来说，也有很多人是大学生，也就是刚刚经历过四六级的英语考试。在备考托福的时候，往往也是很想了解一下，在托福阅读考试中，其难度究竟和英语四六级考试有何差异呢?下面我们就为大家详细分析一下。
托福阅读与四六级阅读难易度差距分析
分段阅读做题，省去“扫读”的时间
在四六级考试中，阅读时间也很少，虽然单词相对简单，但是篇幅较长，逐字阅读肯定是没有时间的，所以做题技巧中扫读是很重要的环节，目的是找到与题目相关的段落或者语句才能找到做题依据。而在托福考试中，是每阅读完一段就做只涉及该段的题目，信息集中，重要的是节省了大量的时间，缓解了托福阅读文章通篇的眩晕感。而这部分题目就是四六级中常说的细节题。
hardest文章说明性强，生词不必怕
托福阅读考试中对单词量的要求还是很大的，即使单词量很大了，也难免会遇上生僻词的情况，而托福考试中选用的文章说明性特别强，往往是自定义 — 自解释的模式，遇到生词，即使不知道什么意思，也可以根据上下文语境弄清它们之间的关系，运用逻辑推理的方法作出正确的答案。其次，还可以分析选项，进行对比，往往会发现选项中通常会出现两个意思相反的选项，此时再仔细重读原文就可以排除错误选项了。
近义词选择有技巧
几乎每段中都会有生词意思辨析题，有些词考生一看就认识，这样的题目就很容易了，但是也不能粗心大意，如果时间富裕或者把握不大，可以把选项带入文章中检查一遍。对于那些不认识的词汇，也是有许多技巧的。首先是分析词性，采用排除法排除词性不一致的选项。其次是用代入法。选项中给出的词意一般就是考生认识的，将选项带入，分析一下是否能够保证原文合情合理，通顺。
分段阅读打基础，全篇文章心里明
在分段阅读的同时，可以记下关键词或者中心句，在文章结束时就可以有根据回想起整篇
smil文章的脉络结构，逻辑关系，对14题的选择有很大帮助。同时题目中也明确给了做题方法，即没有提到的信息或者不重要的观点就可以排除了。
总之，由此我们可以看出，托福的阅读考试，虽然在词汇量和内容量上要高于四六级考试。同时，其阅读内容更加注重逻辑性，所以我们在备考的过程中，要更为讲求方法的应对。cougar town

【1】In 1977 ecologists Stephen Hubbell and Leslie Johnson recorded a dramatic example of how social interactions can produce and enforce regular spacing in a population. They studied competition and nest spacing in populations of stingless bees in tropical dry forests in Costa Rica. Though the bees do no sting, rival colonies of some species fight fiercely over potential nesting sites.
Stingless bees are abundant in tropical and subtropical environments, where they gather nectar and pollen from a wide variety of flowers. They generally nest in trees and live in c
olonies made up of hundreds to thousands of workers. Hubbell and Johnson obrved that some species of stingless bees are highly aggressive to members of their species from other colonies, while other species are not. Aggressive species usually forage in groups and feed mainly on flowers that occur in high-density clumps. Nonaggressive species feed singly or in small groups and on more widely distributed flowers.
【2】Hubbell and Johnson studied veral species of stingless bees to determine whether there is a relationship between aggressiveness and patterns of colony distribution. They predicted that the colonies of aggressive species would show regular distributions, while tho of nonaggressive species would show random or cloly grouped (clumped) distribution. They concentrated their studies on a thirteen-hectare tract of tropical dry forest that contained numerous nests of nine species of stingless bees.

They found that potential nest trees were distributed randomly through the study area. They also found that the number of potential nest sites was much greater than the number of bee colonies. What did the measurements show the rearchers? The number of colonies in the study area was not limited by availability of suitable trees, and a clumped or regular distribution of colonies was not due to an underlying clumped or regular distribution of potential nest sites.
【4】Hubbell and Johnson mapped the nests of five of the nine species of stingless bees accurately, and the nests of four of the species were distributed regularly. All four species with regular nest distributions were highly aggressive to bees from other colonies of their own species. The fifth species was not aggressive, and its nests were randomly distributed over the study area.
【5】The rearchers also studied the process by which the aggressive species establish new colonies. Their obrvations provide insights into the mechanisms that esta
ascendingblish and maintain the regular nest distribution of the species. Aggressive species apparently mark prospective nest sites with pheromones, chemical substances creted by some animals for communication with other members of their species. The pheromone creted by the stingless bees attracts and aggregates members of their colony to the prospective nest site; however, it also attracts workers from other nests.李阳发音宝典

【6】If workers from two different colonies arrive at the prospective nest at the same time, they may fight for posssion. Fights may be escalated into protracted battles. The rearchers obrved battles over a nest tree that lasted for two weeks. Each dawn, fifteen to thirty workers from two competing colonies arrived at the contested nest site. The workers from the two colonies faced off in two swarms and displayed and fought with each other. In the displays, pairs of bees faced each other, slowly flew vertically to a height of about three meters, and then grappled each other to the ground. When the two bees hit the ground, they parated, faced off, and performed another aerial display. Bees did not appear to be injured in the fights, which were apparently ritualized. The two swarms abandoned the battle at about 8 or each morning, only to re-form and
begin again the next day just after dawn. While this contest over an unoccupied nest site produced no obvious mortality, fights over occupied nestssometimes kill over 1,000 bees in a single battle.
