老托福阅读原文 passage12
Among the species of seabirds that use the windswept cliffs of the Atlantic coast of Canada in the summer to mate, lay eggs, and rear their young are common murres, Atlantic puffins, black-legged kittiwakes, and northern gannets. Of all the birds on these cliffs, the black-legged kittiwake gull is the best suited for nesting on narrow ledges. Although its nesting habits are similar to those of gulls that nest on flat ground, there are a number of important differences related to the cliff-nesting habit.
The advantage of nesting on cliffs is the immunity it gives from foxes, which cannot scale the sheer rocks, and from ravens and other species of gulls, which have difficulty in landing on narrow ledges to steal eggs. This immunity has been followed by a relaxation of the defenses, and kittiwakes do not react to predators nearly as fiercely as do ground-nesting gulls. A colony of Bonaparte's gulls responds to the appearance of a predatory herring gull by flying up as a group with a clamor of alarm calls, followed by concerted mobbing, but kittiwakes simply ignore herring gulls, since they pose little threat to nests on cliffs. Neither do kittiwakes attempt to conceal their nest. Most gulls keep the nest area clear of droppings, and remove empty eggshells after the chicks have hatched, so that the location of the nest is not given away. Kittiwakes defecate over the edge of the nest, which keeps it clean, but this practice, as well as their tendency to leave the nest littered with eggshells, makes its location very conspicuous.
On the other hand, nesting on a narrow ledge has its own peculiar problems, and kittiwake behavior has become adapted to overcome them. The female kittiwake sits when mating, whereas other gulls stand, so the pair will not overbalance and fall off the ledge. The nest is a deep cup, made of mud or seaweed, to hold the eggs safely, compared with the shallow scrape of other gulls, and the chicks are remarkably immobile until fully grown. They do not run from their nests when approached, and if they should come near to the cliff edge, they instinctively turn back.

托福阅读技巧：逻辑题三大策略
托福阅读中的推理题是指重要信息隐藏在文章中，不会直接表露出来，需要考生自己从表面内容中推理出。因此，考生们在做托福阅读推理题的时候不能错过每一个信息点，因为这些可能都是最后答案的重要凭证。
推理题的题干中常出现infer, imply , most likely (least likely) 或probably 等词语。根据OG， 在IBT 阅读的3篇文章中，每篇会有0-2道这类问题，一次考试总共有3-4道推断题。
一、推理题的两大分类：有共性的推理题和无共性的推理题。
这 里所谓的有共性推理题就是说题干中有和原文内容相同的关键词(也叫线索)。根据关键词回原文定位，然后进行推理。一般来说，大多数的推理题都属于这类题 目。对于无共性的推理题，也就是题干中无线索，一般使用排除法，即根据各个选项的关键词回原文定位，通过排除法得出正确答案。返回原文找信息点，采用排除 法是解决这两类题型解决的共同策略。
二、推理题的三个具体的解题思路：
1、一般对比推理：
根据两个事情的对比特征，问其中一个事物的特征，只要将与之形成对比的另外一个事情的特征否定掉就可以。
2、时间对比推理：
在这种推理中，一般有两个形成对比的时间段，它们所具有的特征一般相反。当题干问一个时间段的特征时，只要将与之相反的时间段的特征否定掉就可以了。
3、集合概念推理 ：
一个大的集合的两个方面形成对比，两者之间存在着互补性关系，也就是一个的增加意味着另一个的减少。反之，相同。这个比较抽象，我们来看一个例子：
例 如：Both the number and the percentage of people in the United States involved in nonagricultural pursuits expanded rapidly during the half century following the civil war, with some of the most dramatic increases occurring in the domains of transportation, manufacturing, and trade and distribution.
What can be inferred from the passage about the agricultural sector of the economy after the Civil War?
(A) New technological developments had little effect on farmers.
(B) The percentage of the total population working in agriculture declined.
(C) Many farms destroyed in the war were rebuilt after the war.
(D) Farmers achieved new prosperity because of better rural transportation.
文中指出：非农业人口的数量和比例都增加了。由此可知农业人口的数量和比例下降，所以(B)为正确答案。
三、解答这类题目需要注意的信息点：
1.日期和数字。
2.关键词：
表示多少的副词: many , some, much of, several , a few ,most …;
情态动词：may, can , could…;
表示过去的：used to be , was, were , at one time, previously ;
表示不是唯一的： not only ,not exclusively等。
