On January first ,I went to the park in the morning.I went shopping in the afternoon

问题描述:

On January first ,I went to the park in the morning.I went shopping in the afternoon
这段话有错吗
first前加the,还有其他吗

具体到某天的时候是用ON THE MORNING OF ,泛指“在早上”是用IN THE MORNING.所以1.
and i went shopping on the afternoon.这样比较好,请再指教.
