Believe it or not: the more TV you watch, the   (little) happiness you get. This is the result of a new study. It shows that unhappy people watch more TV than happy people.
Well, you may say that you enjoy   (watch ) TV. In fact, TV gives you happiness for a short time, but unhappiness for a long time.
Why? It is because, if you watch TV, you cannot take part in many other good   (activity). And sometimes, if you are unhappy, you   (usual) prefer being a couch potato(整天坐在沙发上看电视的人)，right? Watching TV is relaxing to you.
Then if you want to be happy, what should you do? You can read newspapers, visit   (you) friends, go to parties, … but don’t watch television all the time. Now turn off the TV, and take a walk outside. It’s the   (one) step to being happy!
