以My first time 为题写一篇英语作文我想知道 某人第一次做某事的句式是在多少岁..的句式

My first time to ride a bikeToday I can ride a bike very well.But three years ago,it was too hard for me to ride a bike.Now I still remember my first time to ride a bike.I often fell off the bike,but I didn’t stop riding.First I asked my father to help me with my bike.Next,let him not help me and I rode alone.Then I could ride a few minutes.I kept practising.Finally I could ride a bike to school.I was very happy.From this thing,I know nothing in the world is impossible if you set your mind to do it.
