But when it comes to unhappiness, the twins raised apart-some without contact for as long as 64 years-were as 2______ as those who had grown up together. Why is unhappiness less influenced by 3______? When we're happy we are more responsive to people and keep up 4______ better than when we' re feeling sad. This doesn't mean, however, that some people are born to be sad and that' s that. Unhappiness may be related to genes, but this inherited trait can be influenced by 5______ choice. You can increase your happiness through your own actions. In a whole 6______ of experiments by psychologists John Reich and Alex Zautra at Arizona State University, they asked students to select their favorite activities from a list of everyday pleasures- things like going to a movie, talking with friends and playing cards. Then the researchers 7______ some of the students in the experiment to increase the number of favorite activities they participated in for one month (the other participants in the study 8______ as controls (对照组) and did not vary their activity level). Result: Those who did more of the things they enjoyed were happier than those who didn't. The conclusion, then, is that the pleasure we get from life is 9______ ourselves to control. |
