Question

【题目】Robert is said _______abroad, but I don’t know which country he studied in .

A.to have studiedB.to studyC.to be studyingD.to be studied

Answer 1

【答案】A

【解析】

考查不定式的完成形式。句意：据说Robert曾在国外学习过，但我不知道他是在哪个国家学习的。“据说某人做过某事”是sb. be said to do sth.，“出国学习”发生在谓语之前且动作已经完成，故用不定式的完成形式to have done。故选A。
