Question

【题目】________ is not easy for the children in the mountains to go to school every day.

A. ThisB. ThatC. It

Answer 1

【答案】C

【解析】

句意：山区的孩子每天上学不容易。A. This这，这个；B. That那。那个；C. It它。本题考查句型：It is +形容词+for sb. to do sth. 对某人来说做某事怎么样？It是形式主语，真正的主语是后面的动词不定式to go to school every day。在这种结构中不用this, that。故选C。
