Question

______ we ______ to these immediate crises abroad, we also will not let up in our effort to deal with the pressing, ongoing challenges facing our country.

A．With; will respond

B．As; respond

C．As; answer

D．with; will answer

Answer 1

C

考查狀語從句和固定搭配。With是介詞，后加doing，排除A、D；As“盡管，因為，隨著”，可引導從句。句意“盡管我們在國外負責處理緊急危機，但我們也不會停止作出努力來處理祖國面臨的持續的挑戰。”answer to“適應；符合；承擔責任”；let up“停止；放松；減少”。故選C。
