　　1. Which of the sentences below best expresses the essential information in the highlighted sentence? Incorrect answer choices change the meaning in important ways or leave out essential information.

　　○ Slowing down the process of desertification is difficult because of population growth that has spread over large areas of land.

　　○ The spread of deserts is considered a very serious problem that can be solved only if large numbers of people in various countries are involved in the effort.

　　○ Desertification is extremely hard to reverse unless the population is reduced in the vast areas affected.

　　解析：本题中句子的主语为“the extreme seriousness of desertification”，宾语为“the vast areas of land and the tremendous numbers of people affected, as well as from the great difficulty of reversing or even slowing the process”。整个句子意为：沙漠化的严重性主要是由于所影响的土地面积广，人口数量大，以及逆转或者减慢这一进程的困难大。

　　第一个选项的内容和原文内容恰恰是同义替换;而第二选项中的“because of population growth that has spread over large areas of land”和原文中的意思不同;第三个选项中“The spread of deserts is considered a very serious problem that can be solved only if large numbers of people in various countries are involved in the effort”是关于解决办法的，原文没有提及;第四个选项中的“unless the population is reduced in the vast areas affected”原文中也并未提及。正确答案即为第一个选项。
