求 那位大神看看 下面文章有没有语法错误顺当修改一下
What i can see in the bule sky is the white cloud yet not the cool breeze.A group of wild geese fly far away form south to north,they keep in a shape of herringbone no matter how far they fly.After several
loud echo in the sky,they end within my heart.And I seem to hear:we are on the journey,always smile.
Life has its two sides.You can have a positive attitude to it,just like the wild geese.No matter how far they fly,how tired they feel,they never change the shape of herringbone,never compain.You can also
be negative,being sad and compaining all the time.You may seldom be happy and finally end up in loneliness.
If optimism can make us happier,why not be willing to do it!
