Now I know whether a person is happy or not. In the eleventh paragraph, I find that people act as if they have traits about happiness, they will be happy (可改為people who act as if they have traits about happiness will be happy ). That means people’s attitudes decide people’s feeling.
In the twelfth, I feel surprised that the main element about people’s happiness is genetic makeup. But in my opinion, we don’t feel depressed just because our relatives are unhappy. As the writer said in eleventh paragraph, we can change our attitudes.
The part of the thirteenth, fourteenth and fifteenth paragraph says that close relationship influences the extent of happiness. In my opinion, if some person has many close friends, he or she could express his or her annoyance and the friends would be the loyal listener and help him or her, so his or her happiness appears (comes)fast instead of unhappiness. Maybe (刪去maybe或And)I don’t have marriage experience, so I don’t understand why the people who have bad marriage have more happiness than the single people.
This part lets me know happiness depends on exterior things, and we don’t fear to lose our happiness just because of our age, sex, income and so on. Adjusting My Attitude, I think I will gain more happiness than before.
(I havn't found any other mistakes, Maybe my grammar is very weak.)
