小题1:
Everyone feels happiness, surprise, fear, sadness and anger at some time—these are the basic emotions. It’s normal to have these feelings sometimes! There are over 600 words in English to describe them and we use the muscles(肌肉) in our faces to express them.
小题2:
  Emotions enable us to react to situations—for example, anger will set your heart racing, and feeling happy will make you smile. One of the key areas of your brain that deals with showing, recognizing, and controlling the body’s reaction to emotions is known as the limbic system (中枢边缘系统).
小题3:
 When remembering an emotional event, you recall not only what happened, but also how you felt. Both sorts of memory can be caused by something you heard, saw and even smelt, at the time. Scientists think that you store early emotional memories, even if you can’t remember what actually happened.
小题4:
Taking the time to recognize, understand, and express how we feel is the right thing to do. When we are able to express our emotions properly, we think hand act in a better way. We have better relationships with our parents, family and friends. We understand ourselves, and others understand us. And it feels so good!
小题5:
  The way we feel affects our thoughts and actions, and it is impossible to separate our feelings from the things we think and do! Therefore, it is important to be aware of our feeling and to respond to them in the right way. Feelings like anger and fear are not our enemies! We should not keep them deep inside. Instead, we should understand them and direct them in the proper way.
