Question

【題目】It is _____ must to have a good ______ of a foreign language and a specific skill in such a competitive society.

A. /; view B. a; command C. a; order D. /; permit

Answer 1

【答案】B

【解析】

考查固定句型。句意：在這樣一個(gè)競(jìng)爭(zhēng)激烈的社會(huì)里，掌握一門外語(yǔ)和一門專門技能是必須的。It is a must to do sth.為固定句型，所以句中要用不定冠詞。have a good command of…，為固定搭配，意為“精通……，……掌握的好”，故選B項(xiàng)。
