代入法解题思路实例讲解
原题实例
the deserts, which already occupy approximately a forth of theearth's land surface, have in recent decades been increasingly at an alarmingpace. the expansion of desert--like conditions into areas where they did notpreviously exist is called desertification. it has been estimated that anadditional one-fourth of the earth's land surface is threatened by this process。
the word threatened in the passage is closet in meaning to ----
A、restricted B、endangered C、prevented D、rejected。
思路解析
这道题目问的是threatened这个单词的意思。大部分背了单词的同学都知道是威胁的意思,很容易的就可以选择b答案。但是如果你不认识这个单词呢,我们来看下单词所在这个句子,“估计另外的四分之一的土地被这种进程所-------。”那么这个进程讲的就是前面所提到的沙漠化的进程。我们来看下四个选项,A受限制的, B被威胁的,C被阻止的,D被拒绝的。把这四个单词带入的话,我们得出b 被威胁的这个选项是最合适的。
以上就是托福阅读中代入法解题的思路实例分析,希望能对大家应对难题有所帮助。
