Quy ước kinh, vĩ tuyến gốc?

cho em đi tthi ạ ! đánh xong 1 trận không ai giám thi lun đấy ạ !

Thưa cô cho em nộp bài ạ :

1. Of course I walk often. I usually go 3 times a day. Because walking helps me strengthen my health and train my leg muscles

2. When I was a kid, I walked a lot. I go with relatives in the evening. And when I was a little older, in the morning and afternoon, I went alone. Walking is very fun, enjoying the wind. Bits help reduce stress and fatigue.

3.I think the current number of pedestrians is not much. They mainly depend on means of transportation such as bicycles, buses, cars, etc
