Dear Mr Life ,

　　Thank you for your last lesson in which you managed to teach me how to face the adversity bravely when there is no one to turn to .Yeah,it is just your very lesson that encourage me to try to keep optimistic and engtic.Thanks to it, I swear that henceforth seldom will I feel frustrated and bored no matter how tough and difficult the condition is .

　　A side from this lesson,there also exsit tens of thousands of reasons why i should show my gratefuiness to you .here,let me express my heartfelt appreciaton from the bottom of my brain.Beacause it is you who push me to treasure the every mintue ,every second in my life .do you still remember the unforgotable experience?it is in a cold morning in the winter ,you punished me heavily just because i failed to value my time .

　　And it it you who hoaxed me .thourgh this event ,I learned to be full of vigour and smile to every cheater.Just as Alexander Puskin put it : If by life you were daceived, don not be dismal ,don't be wild . in the day of grief , be mild . merry days will come ,believe. Heart is living in tomorrow ;present is dejected here, in a moment , please sorrow, that which passes will be dear.
