Question

To get a better view of the stage, ____________________.

A．our seats had to be changed.

B．our seats were changed

C．our seats are changed

D．we had to change our seats.

Answer 1

D

试题分析：考查句子结构：非谓语动词（含现在分词/过去分词/不定式）做状语时，其逻辑主语一般都是句子的主语。而能做该句不定式to get a better view of the stage主语的，只能是人，而不能是物。由此一点，可以排除ABC（主语为物）。选D。
点评：非谓语动词做状语的时候，逻辑主语应该和句子的主语一致，所以遇到这类题目，只要找到适合的主语就可以决定正确的选项，这也是做这种题目的捷径，但一定要求分析句子成分。
