七点用英语怎么说两种

七点用英语可以说成两种，分别是 "seven o'clock" 和 "seven in the evening/morning"。

"seven o'clock" 来源于英语中时间表达方式，其中 "o'clock" 意思是“整点”，表示准确的小时数。例如：

I will meet you at seven o'clock. (我会在七点见你。)
The train leaves at seven o'clock sharp. (火车七点整准时开。)

"seven in the evening/morning" 是指在晚上/早上的七点。例如：

I will be home by seven in the evening. (我晚上七点会到家。)
I usually wake up at seven in the morning. (我通常早上七点醒来。)
