Question

【题目】 Life can be hard __________, but you must keep your head held high and stay positive.

Never let anyone bring you down.

A. at all times B. all the time

C. at a time D. at times

Answer 1

【答案】D

【解析】

试题分析：句意：生活可能有时是艰难的，但你必须坚持抬起头，保持积极的心态。永远不要让任何人使你倒下。at all times 总是，一直；all the time一直；at a time依次，逐一；at times有时，间或。所以选D。
