Swimming is very interesting .and many children are good at it but except me.certainly ,i study it before.i usually play with neighbour when i was a child.we play table tennis,football,running and a lot sport.We also swim in the pond.when i was seven years old,it's the first swimming of me.i am swimming around the bank.firstly,i catch a plant and study the posture .then i release the plant,but i am back when i swim forward ,so i swallowed by water,i want to cry but without chance.i have to jump with all strength.Then they find me and push me to a wood.i am safety .I think it's unforgettable,so i never swim too.
