题目内容

I’m putting on weight. The doctor has warned me to _________ sugar.

A. keep up            B. keep back         C. keep off            D. keep away

C


解析:

keep off有“不接近、避免”等意思,在此题中是“不(吃、喝)”之意,又如:keep off cigarettes /drink /fatty food不抽烟/不喝洒/不吃油腻食物。keep up“不低落、维持”;keep back“阻止、不将某物给某人、隐瞒”;keep away“不靠近”。
