小题1: Heather Mccoy

 Entering a bookstore, one cannot help but notice entire shelves devoted to books boating knowledge of the true path to happiness.

 Whether this wave of commercials and books can actually make people happier is the question. Happiness cannot be found by sticking to a narrow set of steps or rules. Finding happiness is not as simple as following a how-to-do handbook. It’s something that every person must find in his or her own way.

小题2: Gary Russell

 Does happiness grow proportionally with wealth? Hardly.

 Experiences teaches us material satisfaction comes only when one finds himself wealthier than those around him; and, in a similar manner, one feels of being lowered when facing a billionaire, while a worker with a monthly salary of several hundred dollars becomes the envy of the villagers in remote mountainous regions.

小题3: David Niven

 True happiness is not a result from human action. Results are temporary while happiness is everywhere and can neither be created nor destroyed. With true happiness there is no place for disappointments! True happiness may mean pain and restraint in the beginning but will lead to everlasting joy and freedom. To achieve true happiness, we should separate and remove the negatives. True happiness is realized by understanding one’s own self.

小题4: Joshua Party

 Happiness is a state of mind. you can be happy in almost any situation. Likewise, you can be unhappy in an equal number of situations.In the end, it’s your decision.

 If one can control one’s unhappiness, then one must be able to control one’s happiness. As far as I know, the human genome project has not been able to identify a single part of any human chromosome(染色体) which is responsible for happiness.

小题5: Laura Johnson

 So what makes me a happy person? Studying to be a journalist because I loved to write, not because it pays a lot of money. Skiing in the winter snow and swimming in the summer sun. Spending time with my close friends from home. Being in a stable family. Reading romance novels and watching movies. Having a boyfriend who knows more about rock and roll history than I do.
