下午，体育课上蒋老师老师上半节课叫我们女生玩游戏，叫男生跳绳。下半节课，蒋老师叫我们调换一下。
In the afternoon, Mr. Jiang asked us girls to play games and boys to jump rope for the first half of the class. In the second half of the class, Mr. Jiang asked us to change.
我们跳绳的`时候没有专心致致，但是我却觉得时间过得飞快。
We didn't concentrate on skipping, but I felt that time passed quickly.
后来李老师叫我们集合的时候已经下课了。
Later, when Miss Li asked us to gather, class was over.
今天我很开心。
I'm very happy today.
