Question

【题目】He was still full of optimism for the future despite many problems, and never once ______ him get worried or upset.

A. I saw B. I would see

C. did I see D. would I see

Answer 1

【答案】C

【解析】

考查倒装句式。句意为：尽管有许多问题，他对未来仍然充满乐观，我从未见过他感到忧虑或不安。and连接两个并列句，后面一个句子是以否定词never开头，故用倒装结构，助动词置于主语前，且从前面的句子时态来看，确定是用一般过去时，故选C。
