图表题
题型介绍
总结题与表格题是唯一全文考察题型,不同的是:
总结题为分论点概括题(不选细节选项),表格题为文章细节分类题(都是细节选项)。
表格题的文章必为比较类文章。
做题技巧
本题做法与正面信息题类似。关键在于回查。由于机考的界面不能同时展示问题和文章,就需要先摘录选项,再回查。
记笔记的同时整理出一些条理:
1. 内容不在分类之内的不选;
2. 选项间有对比性的通常都是正确答案。
出题频率和分值
图表题和总结题在每篇文章中只出现一题。撇开加试不算,一般一次托福考试只出现一个图表题(另两篇总结题) ,但分值为整个托福阅读单项最高,一定要给予足够的时间。
7选5, 3分
10选7, 4分
Sand Dunes
Sandy deserts contain enormous volumes of sand eroded from mountains and carried to the deserts by wind or water. The huge quantities of sand that make up sandy deserts are blow about into dunes of various shapes.
Ridge dunes form where there are large amounts of sand, generally in the interiors of deserts, and winds blow in one direction. Under these conditions, parallel ridges of sand, known as transverse dunes, form at right angles to the wind.
When the direction of the wind changes so that es from different directions, star-shaped dunes form from the massive amounts of sand in desert interiors. Star-shaped dunes are relatively stable dunes that reach incredible heights, up to 80 meters high in some deserts, and are mon in massive deserts such as the Sahara.
Crescent dunes form on the edges of deserts where there is less sand and where the winds blow mainly in one direction. These dunes, which are also known as barchan dunes are less stable than star-shaped dunes and can shift as much as 20 meters per year as winds blow over the outer curves of the crescent in the direction of the pointed ends.
