If you _____ the bottle and cigarettes, you we’ll be much healthier.

A．take offB．keep offC．get offD．set off

B

解析試題分析：句意：如果你煙、酒不沾的話，你將會健康得多。take off起飛，脫下；keep off不接近；get off下車；set off出發(fā)。根據(jù)句意故選B。
考點：考查動詞短語辨析。
點評：本題難度適中。動詞短語是近幾年高考的熱點，不僅在單選還會出現(xiàn)在完形和短文改錯中，主要考查對短語的意義和用法的掌握，同時要求考生正確理解語境。這里考生容易誤選A。
即學(xué)即練: The burning gas was easy to _____an explosion.
A. take off         B. keep off         C. get off           D. set off
解析：D。句意：燃燒的煤氣容易引起爆炸。
