– ______ do I have to take the medicine? – Three times a day, after meals. A．How long B．How far C．How often D．How soon

Answer 1

C

试题分析：句意:-我应该多长时间吃一次药？-一天三次，饭后。根据这个情景中的回答three times a day，可知，这里是询问吃药的频率，即多久吃一次，提问频率应该用how often。how long 多长时间，对一段时间提问；how far 多远，提问距离；how soon 多久，多快；how often 多久一次。故选C。
