( C ) 7.— I can’t keep myself active during the day.
— You ____ take more exercise.
A.must not B.must be C.need to D.needs
告诉我这题为什么选c.
He spent —— time in playing when he was in the medical college.
( ) A.much B.a little C.no D.little
还有这题
( C ) 7.— I can’t keep myself active during the day.
1.根据句意.我今天都没有活力.(我不能保持活力)
首先MUST表示必须,是强制性的,所以AB都不选.D前面是You 而不是第三人称不用加S.所以选C need to do sth
2.他在念医学院的时候花了--时间去玩.可以看出学医,所以应该很少,从选项也可看出B C D 均表示没有,一点.其次时间不可数.
若C 的表达应该为He didn't spent much/any time in.否定要放在前面.所以Little 表示几乎没有,
选D
