阅读理解。     For hundreds Of years, scientists have been trying to answer what things have an effect on people's emotions (情感). How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don't know your emotions can be influenced by the weather as well.      People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, our bodies produce a vitamin. Vitamins are natural chemicals (化学物质) which we all need to stay healthy. Sunlight helps our bodies produce vitamin D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains (大脑) and makes us feel happy. For example, there are long, dark winters of little sunlight in Sweden and Norway, so many people in the countries often feel sad. Without much sunlight, their bodies produce less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes them feel good. To help the people in the countries feel better, special "sunrooms" with artificial (人造的) lights have been built. People can go there and get "sunlight" for an hour or two!      The weather can also affect people's emotions in other ways. Hot weather can make people angry becau people feel uncomfortable when they are hot. In the same way, rain can make people angry becau being wet can be unpleasant. As you can e, the weather can have an effect on the chemicals which control our brains. Through the ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather. 1. Which of the following is NOT mentioned as a factor (因素) that can affect one's emotions? A. Weather. B. Actions of others.

We will be happy when we are caught in the rain. C. All people in Norway and Sweden feel sad in winter. D. The more vitamin D you have, the happier you'll be. 4. What may be the best title for this passage? A. Why Do We Feel Sad? B. The Weather Influences People's Emotions C. People Need More Vitamin D D. We Can Hardly Change the Weather
