托福阅读应试技巧之阅读表格题
欢迎来到查字典出国留学网托福频道，本网站根据各位托福考生的需求，为大家精心整理了大量与托福考试相关的信息，包括考试报名、考试资料、成绩查询等，希望对大家有所帮助。
这类题考的很少，大家碰到的几率也不高，一般是那种文章本身就在说两个事情的，怎么做呢??还是要会分析文章结构，这个也属于内力范畴!
表格题类似于not except型，一般是7选5，或者9选7.给你两个部分，让你去填充。借鉴 not except 的思路，用哪两个部分给文章的段落分类，然后在分出的各自段落中寻找对应的信息。哎
说的还是好抽象，看例子吧。
GEOLOGY AND LANDSCAPE
1.Most people consider the landscape to be unchanging, but Earth is a dynamic body, and its surface is continually altering-slowly on the human time scale, but relatively rapidly when compared to the great age of Earth (about 4,500 billion years). There are two principal influences that shape the terrain: constructive processes such as uplift, which create new landscape features, and destructive forces such as erosion, which gradually wear away exposed landforms.

2.Hills and mountains are often regarded as the epitome of permanence, successfully resisting the destructive forces of nature, but in fact they tend to be relatively short-lived in geological terms. As a general rule, the higher a mountain is, the more recently it was formed; for example, the high mountains of the Himalayas are only about 50 million years old. Lower mountains tend to be older, and are often the eroded relics of much higher mountain chains. About 400 million years ago, when the present-day continents of North America and Europe were joined, the Caledonian mountain chain was the same size as the modern Himalayas. Today, however, the relics of the Caledonian orogeny (mountain-building period) exist as the comparatively low mountains of Greenland, the northern Appalachians in the United States, the Scottish Highlands, and the Norwegian coastal plateau.

3.The Earth's crust is thought to be divided into huge, movable segments, called plates, which float on a soft plastic layer of rock.1 Some mountains were formed as a result of these plates crashing into each other and forcing up the rock at the plate margins. In this process, sedimentary rocks that originally formed on the seabed may be folded upwards to altitudes of more than 26,000 feet.2 Other mountains may be raised by earthquakes, which fracture the Earth's crust and can displace enough rock to produce block mountains.3 A third type of mountain may be formed as a result of volcanic activity which occurs in regions of active fold mountain belts, such as in the Cascade Range of western North America. The Cascades are made up of lavas and volcanic materials. Many of the peaks are extinct volcanoes.

4.Whatever the reason for mountain formation, as soon as land rises above sea level it is subjected to destructive forces. The exposed rocks are attacked by the various weather processes and gradually broken down into fragments, which are then carried away and later deposited as sediments. Thus, any landscape represents only a temporary stage in the continuous battle between the forces of uplift and those of erosion.
注意第一句，我们要寻找的东西出现了，destructive force.这说明前面的是con的部分。后面在说erosion
5.The weather, in its many forms, is the main agent of erosion. Rain washes away loose soil and penetrates cracks in the rocks. Carbon dioxide in the air reacts with the rainwater, forming a weak acid (carbonic acid) that may chemically attack the rocks. The rain seeps underground and the water may reappear later as springs. These springs are the sources of streams and rivers, which cut through the rocks and carry away debris from the mountains to the lowlands.
还在说erosion，各种举例
6.Under very cold conditions, rocks can be shattered by ice and frost. Glaciers may form in permanently cold areas, and these slowly moving masses of ice cut out valleys, carrying with them huge quantities of eroded rock debris. In dry areas the wind is the principal agent of erosion. It carries fine particles of sand, which bombard exposed rock surfaces, thereby wearing them into yet more sand. Even living things contribute to the formation of landscapes. Tree roots force their way into cracks in rocks and, in so doing, speed their splitting. In contrast, the roots of grasses and other small plants may help to hold loose soil fragments together, thereby helping to prevent erosion by the wind.
Ice和frost也会起作用，然后living things也起作用，比如树根和草根。
12. Directions: Three of the answer choices below are used in the passage to illustrate constructive processes and two are used to illustrate destructive processes. Complete the table by matching appropriate answer choices to the processes they are used to illustrate. This question is worth 3 points.
CONSTRUCTIVE PROCESSESDESTRUCTIVE PROCESSSES
●1
●5
●6●3●7
Answer Choices：
○Collision of Earth's crustal plates
○Separation of continents
○Wind-driven sand
○Formation of grass roots in soil
○earthquakes
○Volcanic activity
○Weather processes
先看分类的两部分，一个是CONSTRUCTIVE PROCESSES，一个是DESTRUCTIVE PROCESSSES
回文章寻找吧，这里涉及读文章的能力，我简单说一下。回上面的文章看
通过以上的文章分析，大家就清楚了这两部分的所在，然后具体的找一下运用not except的解法就可以了。
Con的在第三段，那三个原因。De在四六段的前部
