It is very important for us to _______and work hard.

A．keep fit B．keep fat
C．keeping fit D．keeps fat

A

解析試題分析：句意：保持健康和努力工作對(duì)于我們來(lái)說(shuō)是非常重要的。分析：考查固定句型：It is +adj.+ to do sth. 因此接動(dòng)詞原形，分析：結(jié)合選項(xiàng)內(nèi)容，keep fat與keep fit，對(duì)于我們健康重要的一定是keep fit.故選A
考點(diǎn)：考查非謂語(yǔ)動(dòng)詞的用法。
