[　　Last summer I learnt to ride a bicycle．At first, I was

unable to control its direction．Sometimes I fall to

the right or to the left．I worried to ask my father

impatiently how I could ride straight, so he didn't

answer me directly．Instead, he took me to side of the

Street．Can you find any bike track is really straight?

Asked my father．I watched more carefully and shook my

Head．No, he said, in fact, neither of the tracks is

always straight．But just by correct the direction

Every now and then, you had already gone forward．
