几道英语题目求解,高手进!
Uncle Jim is busy today.He______to our party tonight.(not come)
The police quickly_____ the driver when he was driving too fast.(stop)
还有一个问题哦,是in the early morning还是on?我用百度查了还是不确定、、、
我也认为是in，不过百度词典有“on the early morning"中文显示是某一天早晨，不信可以把词组打进去查一下。

答案

won't come
stopped
in the early morning 是对的,没问题
on后面加具体某天,
而in表示某天的三个时段
