Example 3: Weather can affect many things. Besides the growth of corn and the quality of air, it can also affect human emotions. Different weather conditions may provide different backgrounds for various stories. The rapid changes of clothes due to changeable weather, for example, an unexpected fever as temperature decreases, may affect people's moods to a large extent. As for me, I prefer a clear day with warm sunshine and tasty breeze. In contrast, I'll feel extremely anxious in a windy or rainy day. The heavier the wind or the rain is, the worse my mood will be. It is evident that I have to pay so much attention to prevent the wind or the rain from blowing my things away or wetting my books in hand that I have no time to appreciate the scenery around, feeling tense and irritable. What is worse is that the weather in recent years seems to be increasingly changeable and a spell of（某事情持续的）一段时间）sudden rain, heavy wind is becoming common in our daily life. In my view, this is another symbol of the bad tendency of weather change besides the increasing number of worldwide disasters. Being affected by weather every day, we have to take immediate measures to protect our environment.
