書面表達：

The weather depends on the sky, but whether you are happy or not depends on yourself.

I can well remember that I didn’t pass the Chinese exam several times last year, so the weather of my sky seemed to be full of clouds. Although the songs of birds were very nice and the flowers were very beautiful, they could not let me escape from depression. What’s more, I felt that I was laughed at by all the other classmates. My Chinese teacher noticed my subtle difference, so she gave me some advice and told me to change my attitude. With the help of her, I tried to face the trouble with a positive attitude. To my surprise, everything changed. It was not long before I made great progress in my Chinese.

Life is full of difficulties. Sometimes you may not be able to decide the situation you are in, but you can change your attitude.
