历年托福考试语法真题全面解析62
26. Because aluminum is nonmagnetic, it is value for protecting electrical equipment from magnetic interference.答案：B
测试点：词性.
分析：value这个词，以及与之有关的各种形式，常常出现在考题中．此处应用其形容词valuable作表语.
27. Nitrogen and oxygen are too important that most living organisms cannot survive without these elements.
答案：B
测试点：so…that与too…to…的用法.
分析：这两个结构常被错误搭配．看到后文无to而有that，应知此处too应为so。
28. Coal and petroleum resulted when plants become buried in swamps and decayed.
答案：C
测试点；时态／并列结构.
分析：主句为过去时(resulted)，时间状语从句不能用现在时．and连接两个并列的谓语部分，其一边为过去时的decayed,另一边也应是过去时的动词．应为became．亦可从句意方面分析；煤和石油的成因是远古时期的事情，不应用现在时.
29. Percapita income is a nation’s entire income dividing by the number of people in the nation.
答案：B
测试点：过去分词表示被动.
分析：接在名词后面作定语时，divided by是固定的短语，相当于省略的从句(that／which is)divided by"：这里应用过去分词表示被动的意思。
30. Jim Thorpe, a football, track, and baseball stars from Pennsylvania, is considered by many to be the greatest all-around athlete of modern times.
答案：B
测试点；数的一致.
分析：冠词a后应是单数名词．另外，此处的成分为主语的同位语t主语为单数，其同位语也应是单数的star.
