Question

Jack almost fell off the cliff, but managed to _____ until help came.

A. keep on    B. catch on    C. count on     D. hang on

Answer 1

D. hang on

解析:

hang on(=hold fast, keep hold)牢牢抓住，抓紧不放：Help! I can't hang on much longer.(救命啊！我支持不住啦。)keep on(doing sth.)继续（做......）；catch on 理解；count on 指望，依赖。本题译文：杰克差点从悬崖上掉下来，但得以抓住不放直到得救。
