问题 Most of our fears are unreasonable, but we find ______.
选项 A、it impossible to erase them
B、that they can not erase
C、them to erase impossible
D、erasing them impossible
答案 A
解析 本题测试it做形式宾语的用法。A选项中的it指代to erase them，构成了语法上的特殊结构。it除此种用法之外，还可以做形式主语，如：It is hard for us to get along well with superiors in work. (我们很难在工作上和上司处好关系。)这里的it也指代其后的不定式短语。it的上述两种用法，主要是出于句子结构的需要。所以A选项是正确答案。B选项erase是及物动词，缺少宾语，所以错误。C选项结构错误。D选项中修饰词impossible错误，因为不能用形容词来修饰动词，所以将其排除。
