【題目】 you may have, you should gather your courage to face the challenge.

A.However a serious problem B. What a serious problem

C.However serious a problem D. What serious a problem

【答案】C

【解析】

試題解析：考查讓步狀語從句。先分析句子結(jié)構(gòu)，主句為逗號后面的部分，而逗號前面的部分用作狀語。what不可引導(dǎo)狀語從句，故排除B項(xiàng)。故應(yīng)為however引導(dǎo)的讓步狀語從句，意為無論，不管，其結(jié)構(gòu)為however+形容詞/副詞+主語+謂語。其中，however也可以換成no matter how，轉(zhuǎn)換為正常語序后為：You may have a serious problem。句意：無論你遇到多么嚴(yán)重的問題，你都應(yīng)該鼓起勇氣面對挑戰(zhàn)。故選A。
