She _____ very little food every day because her doctor advises her to keep on a diet.But i'm sure she'll soon relapse to her old habit of overeating.
a.eats b.has eaten c.has been eating d.is eating
这题 为什么选D 为什么不能选C?
答:此题考时态的用法.你为什么不问“为什么不用A呢?”
这里的时间状语every day是最大的干扰,因为常见于一般现在时,表示每天都会发生的情况.
C是现在完成进行时,时间状语应为now,so far,不会是every day.
D.是现在进行时,除了表示现在这个时刻正在发生的动作外,还可以表示“现阶段正在进行的动作”.且有感情色彩.本题句属于这种情况.
译:他现在天天吃得很少,因为医生建议他要节食.不过我肯定她多吃的老习惯很快会复发的.
