Question

_______, I lost heart in English learning, but my teacher said to me, “Keep on working hard, and you’ll succeed ________.”

A．At a time; in time	B．At one time; in time
C．At a time; on time	D．At one time; on time

Answer 1

B

试题分析：句意：从前我对学英语失去信心了，但是我的老师对我说，“努力学习下去，迟早你会成功的”。at a time 依次,逐一,每次. at one time一度,从前. in general 一般的，大概  in advanced 预先 in time 及时，迟早的意思 on time 按时，所以答案是B。
考点: 考查介词短语的用法。
