Question

【题目】I thought Betty might be nervous to make a speech in front of so many people, but _______ she was confident.

A.in factB.after allC.by mistakeD.at first

Answer 1

【答案】A

【解析】

句意：我原以为贝蒂在这么多人面前演讲可能会紧张，但事实上她很自信。

考查介词短语辨析。in fact事实上；after all毕竟；by mistake错误地；at first起初，首先。but表示转折关系，此处指事实上她很自信。故选A。
