I did not do well on the writing exam, for the topic to write on was unfamiliar_____me.
A、to
B、for
C、with
D、about
【正确答案】:A
【名师解析】:选项A "to" 是正确的答案。在英语中,"be unfamiliar to" 是一个常见的短语,用来表达某事物对某人来说是不熟悉的。在这个句子中,"the topic" 是主语,"was" 是系动词,"unfamiliar" 是形容词,"to me" 表示这个主题对"我"来说是不熟悉的。其他选项 "for", "with", 和 "about" 并不适用于这个短语结构。
