Directions: Read the following passage.Answer the questions according to the information given in the passage and the required words limit. Many people pursue goals that they hope will make them happy, but happiness is not always the final result. So how does one determine and establish which goals will end in personal happiness and which will not ? what are the things in life that are correlated with personal happiness? The most important thing is people’s attitude toward life, which can greatly impact their personal levels of happiness and satisfaction with life overall. Psychologists have known for some time that optimism is a good defense against unhappiness. It’s probably no secret that optimistic people are considered to be much more happier people than pessimists. There are specific characteristic features optimists have (pleasant ways of thinking), that bring them more success, greater health, increased life satisfaction, and other good things. If you became an optimist, it can mean that you became a very happy person, despite your circumstances, and it can actually bring more things into your life to be happy about. “If you are optimistic and you think life is going to get better, it will become a self-fulfilling prediction”, says one of the scientists. “Happy people manage to look on the bright side, even if they encounter big problems on their way.” Positive psychologists believe that people can learn how to become happy, that everyone can teach themselves to see a half-empty glass as half-full. All they have to do is to spend time thinking about all the things that have gone right for them, rather than complaining what has gone badly. Study on depression shows that one of the biggest causes of depression is thinking and worrying about something that went wrong in the past. 小题1:According to the passage, what can affect people’s personal levels of happiness?
