Scientists in Germany carried out some studies on different weather.
   The scientists found that when it's sunny outside，most people are much happier than when it's rainy and cold.Sunlight also makes people feel less tired.Some people like sunny and warm days because they are able to go out and enjoy the weather.And they can also get more vitamin D and better sleep when they get more sunlight during the day.But some people like rainy and cold days because they can watch movies，spend more time with family，and be easily focused （集中注意力） on schoolwork other than putting their work off and going outside to enjoy their days.A university student，Jenny Brown says that she likes to go to school on rainy days and she can do well in her study during these days.
   Scientists say that during the spring and summer，people exercise more and become much thinner and healthier than during the fall and winter.This is because during the spring and summer，people often go for a walk or run with friends when the sun's out and it's warm outside.
   Scientists also find that people get more weight during the winter and fall months because they are inside watching movies and eating rather than going outside and doing sports.People also get upset during the fall and winter because of cold，rain and cloudy skies.And when people are unhappy，most of them usually eat more to make themselves feel happy，but at the same time，they get overweight.
   Weather does affect（影響）our lives，but we can light up our lives and decide （決定） how we feel every day.
