Question

【題目】Don't try to do everything at once. Do one ________．

A. at times B. at any time

C. at a time D. at all times

Answer 1

【答案】C

【解析】句意：不要試圖同時(shí)做每件事。一次做一個(gè)。考查介詞短語辨析題。A. at times有時(shí)，間或，相當(dāng)于sometimes；B. at any time隨時(shí)，任何時(shí)候；C. at a time依次，每次；D. at all times每時(shí)每刻，相當(dāng)于always。根據(jù)句意語境，可知ABD三項(xiàng)意思都與句意不合，故選C。
