As a teacher, we should try to _______ it _______ to our students how helpful a correct learning method is.

get, about

get; away

get; across

get; off

答案及解析：本题考查动词短语辨析C选项，句意为“作为老师，我们应该尽量让学生理解一种正确的学习方法是多么的有帮助”。get across在此意为“使……被理解”，符合题意，综上，C选项正确。A选项，get about “四处走走；（消息等）传播出去”，故排除。B选项，get away“离开；逃脱，逃跑”，故排除。D选项，get off “动身；逃脱惩罚”，故排除。故正确答案为 C项。
