托福阅读难点题型解题思路实例讲解推断题正确解答案例分析

托福阅读因果关系词介绍

托福阅读中的因果关系词其实有两类，一个是表示原因的：as、since、thanks to、as result of、because of、owing to、result from、due to、on account of、by virtue of、in that、attribute to;另一个是表示结果的：as a consequence、thus、hence、so、as a result、result in、contribute to、lead to、cause、breed、trigger.

托福阅读推断题如何用因果关系来解题?

Paragraph 4: So, in another set of experiments, Kramer putidentical food boxes around the cage, with food in only one of the boxes. Theboxes were stationary, and the one containing food was always at the same pointof the compass. However, its position with respect to the surroundings could bechanged by revolving either the inner cage containing the birds or the outerwalls, which served as the background. As long as the birds could see the Sun,no matter how their surroundings were altered, they went directly to thecorrect food box. Whether the box appeared in front of the right wall or theleft wall, they showed no signs of confusion. On overcast days, however, thebirds were disoriented and had trouble locating their food box.

Which of the following can be inferred from paragraph 4 aboutKramer’s reason for filling one food box and leaving the rest empty?

A He believed the birds would eat food from only one box.

B He wanted to see whether the Sun alone controlled the birds'ability to navigate toward the box with food.

C He thought that if all the boxes contained food, this woulddistract the birds from following their migratory route.

D He needed to test whether the birds preferred having the food atany particular point of the compass.

首先，我们来明确一下推断的定义(infer, imply, indicate)，纵使它是推断题，也不是意味着这题是主观臆断，臆想或是联想得出的。这道题也是要通过提取题干中的关键词到文章中的明确位置，然后文中没有平铺直叙地告诉你答案，需要我们根据一些线索找到答案。

接下来我们来看一下这道题，题干中出现Kramer, filling one food box andleaving the rest empty定位在第四段第一句：with food in only one of the boxes，而解开这道题的重点就在于：reason。我们看到第一句话一开始说到，so, in another set of experiments，很明显，答案并不在这一段，而是上一段的最后。所以答案是B。

托福阅读100个长难句实例分析

原句案例：

A fertile, plowed field is rapidly invaded by a large variety of weeds, whereas a neighboring construction site from which the soil has been compacted or removed to expose a coarse, infertile parent material may remain virtually free of vegetation for many months or even years despite receiving the same input of seeds as the plowed field.

词汇讲解：

fertile /'fɜːtaɪl/ adj. (指土地)肥沃的, 富饶的;(指动植物)能结果实的, 能生育的;(指人的头脑)主意多的, 有创造力的

plow /plau/ v. 犁<地>，用犁耕<地>

compact /kəm'pækt/ v. 将(某物)紧压在一起

coarse /kɔːs/ adj. 粗糙的;(指食物﹑ 酒等)低劣的, 粗劣的;不高雅的，粗俗的;

结构划分：

A fertile, plowed field is rapidly invaded (by a large variety of weeds), whereas a neighboring construction site (from which the soil has been compacted or removed to expose a coarse, infertile parent material) may remain virtually free of vegetation (for many months or even years) (despite receiving the same input of seeds as the plowed field.)

深度分析：

这个句子的主干部分是：

A fertile, plowed field is rapidly invaded whereas a neighboring construction site may remain virtually free of vegetation

whereas然而，表示对比，对比两种情况

修饰一：(by a large variety of weeds) ，介词短语

中文：被各种各样的杂草

修饰二：(from which the soil has been compacted or removed to expose a coarse, infertile parent material) ，从句，修饰a neighboring construction site

这个句子理解的难点应该就在这里了，这个从句把a neighboringconstruction site和may remain virtually free ofvegetation分开了，注意断句不要出问题。

中文：这里的土壤被紧压或移除过以至于露出母质层(不要去理解啥是parent material，学术名词)

修饰三：(for many months or even years) ，介词短语

中文：几个月偶然甚至是几年

修饰四：(despite receiving the same inputof seeds as the plowed field.) ，介词短语

中文：尽管得到了和这块翻耕地同样多的种子

参考翻译：

一块肥沃且被翻耕过的土地会被各种各样的杂草迅速入侵，然而一个邻近的建筑工地(这里的土壤被紧压或移除过以至于露出母质层)可能几个月甚至几年都几乎没有植被覆盖，尽管得到了和这块翻耕地同样多的种子。

It is estimated that over 99 percent of all species that ever existed have become extinct. What causes extinction? When a species is no longer adapted to a changed environment, it may perish. The exact causes of a species' death vary from situation to situation. Rapid ecological change may render an environment hostile to a species. For example, temperatures may change and a species may not be able to adapt. Food resources may be affected by environmental changes, which will then cause problems for a species requiring these resources. Other species may become better adapted to an environment, resulting in competition and, ultimately, in the death of a species.

The fossil record reveals that extinction has occurred throughout the history of Earth. Recent analyses have also revealed that on some occasions many species became extinct at the same time — a mass extinction. One of the best-known examples of mass extinction occurred 65 million years ago with the demise of dinosaurs and many other forms of life. Perhaps the largest mass extinction was the one that occurred 225 million years ago, when approximately 95 percent of all species died, mass extinctions can be caused by a relatively rapid change in the environment and can be worsened by the close interrelationship of many species. If, for example, something were to happen to destroy much of the plankton in the oceans, then the oxygen content of Earth would drop, affection even organisms not living in the oceans. Such a change would probably lead to a mass extinction.

One interesting, and controversial, finding is that extinctions during the past 250 million years have tended to be more intense every 26 million years. This periodic extinction might be due to intersection of the Earth's orbit with a cloud of comets, but this theory is purely speculative. Some researchers have also speculated that extinction may often be random. That is, certain species may be eliminated and others may survive for no particular reason. A species' survival may have nothing to do with its ability or inability to adapt. If so, some of evolutionary history may reflect a sequence of essentially random events.

The lack of printing regulations and the unenforceability of British copyright law in the American colonies made it possible for colonial printers occasionally to act as publishers. Although they rarely undertook major publishing project because it was difficult to sell books as cheaply as they could be imported from Europe, printers in Philadelphia did publish work that required only small amounts of capital, paper, and type. Broadsides could be published with minimal financial risk. Consisting of only one sheet of paper and requiring small amounts of type, broadsides involved lower investments of capital than longer works. Furthermore, the broadside format lent itself to subjects of high, if temporary, interest, enabling them to meet with ready sale. If the broadside printer miscalculated, however, and produced a sheet that did not sell, it was not likely to be a major loss, and the printer would know this immediately, There would be no agonizing wait with large amounts of capital tied up, books gathering dust on the shelves, and creditors impatient for payment.

In addition to broadsides, books and pamphlets, consisting mainly of political tracts, catechisms, primers, and chapbooks were relatively inexpensive to print and to buy. Chapbooks were pamphlet-sized books, usually containing popular tales, ballads, poems, short plays, and jokes, small, both in formal and number of pages, they were generally bound simply, in boards (a form of cardboard) or merely stitched in paper wrappers (a sewn antecedent of modern-day paperbacks). Pamphlets and chapbooks did not require fine paper or a great deal of type to produce they could thus be printed in large, cost-effective editions and sold cheaply.

By far, the most appealing publishing investments were to be found in small books that had proven to be steady sellers, providing a reasonably reliable source of income for the publisher. They would not, by nature, be highly topical or political, as such publications would prove of fleeting interest. Almanacs, annual publications that contained information on astronomy and weather patterns arranged according to the days, week, and months of a given year, provided the perfect steady seller because their information pertained to the locale in which they would be used.

(A) required a small financial investment and sold quickly

(D) generally dealt with topics of long-term interest to many colonists

4. The word they in line 17 refers to

(A) chapbooks

(B) tales

(D) pages

(A) predecessor

(B) format

(D) component
