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

解析:

　本題譯文：杰克差點從懸崖上掉下來，但得以抓住不放直到得救。hang on(=hold fast, keep hold)牢牢抓住，抓緊不放：Help! I can't hang on much longer.(救命啊！我支持不住啦。)keep on(doing sth.)繼續（做......）；catch on 理解；count on 指望，依賴。
