【正确答案】This little poem is mainly talking about optimism and persistence when encountering difficulties. When it rains, just hold your breath and work through the rain and don't let happiness pass you by. You should believe in yourself and spread your wings and fly. You have done so well in your part and when things get rough, do not complain. Though the poem is simple and short, it is very warm and encouraging in its tone. Most people tend to become fragile when they are in difficulties. At this time, complaining and giving up cannot make you happy. Only when you believe in yourself and hold on a little bit, you will gain the true happiness and spread your wings and fly. And when we see other people beside us in the same situation, we should encourage them to persist and never give up easily, just as the poet did in this poem to warm us. If everyone has this concept in mind, we will all spread our wings and fly into the sky. If we can do the basic things well enough in our daily life, we will have no regrets because we have already tried our best.
