①What do you do when you feel unhappy? Do you listen to music or talk to a friend? There are two ways to make you happy.
②You should try going outside if it's sunny. Much sunlight we get can change how we feel. Scientists learned this by asking people who live in different parts of the world. In the far north, in Alaska or Finland, for example, the days are very short in winter. In the south, where there are more daylight hours, fewer people say they are unhappy in winter. The reason has to do with the sunlight that these people get each day. Sunlight changes the chemicals(化学物质)in our bodies, and these chemicals can change the way we feel. A few hours of strong sunlight can help our bodies make the chemicals that make us feel happy.
③Another way to feel happier is to get some exercise. Just like sunlight, regular exercise helps our bodies make the chemicals that make us feel happier. Also, exercise helps people sleep better. Not getting enough sleep often makes people feel unhappy. Exercise also helps us lower stress. When we are angry or sad about something, exercise is a good way to get those bad feelings out of us.
④In fact, we can still find many other ways to make ourselves happy.

答案
四、16—19. BDAC
【文章大意】本文是一篇说明文。文章主要介绍了让人感到快乐的方法与原理，并补充说明还有其他能让人开心的方法。
16. B【思路点拨】细节理解题。根据第二段“In the far north ... the days are very short in the winter. In the south, where there are more daylight hours ...”可知，生活在更北边的人更容易不开心是因为冬季日照时间短，获取的阳光更少。故选 B。
17. D【思路点拨】细节理解题。根据第二段“Sunlight changes the chemicals in our bodies, and these chemicals can change the way we feel”可知，阳光能改变人体内的化学物质，从而改变人的情绪。故选 D。
18. A【思路点拨】文章结构题。通读全文可知，本文为“总——分——总”结构：第一段总述有两种能让人开心的方法；第二、三段分述晒太阳和做运动这两种方法能让人开心的原理；第四段总结全文并补充说明还有其他让人开心的方法。故选 A。
19. C【思路点拨】最佳标题题。通读全文可知，本文围绕如何让自己感到更快乐展开。故选 C。
