[单选题]氨制冷系统所有管道应采用（）

[问答题]Practice 3　 Directions: Read the pieces taken from five letters to a magazine by five people talking about happiness. For questions 1 to 5, match the name of each person (61 to65) to one of the statements (A to G) given below. Mark your answers on ANSWER SHEET 1.　　Heather McCoy:　　Entering a bookstore, one cannot help but notice entire shelves devoted to books boasting knowledge of the true path to happiness.　　Whether this wave of infomercials and books can actually make people happier is the question. Happiness cannot be found by adhering to a narrow set of steps or rules. Finding happiness is not as simple as following a how-to manual, it is something that every person must find in his or her own way.　　Gary Russell:　　Does happiness grow proportionally with wealth? Hardly.　　Experience teaches us material satisfaction comes only when one finds himself wealthier than those around him; and, in a like manner, one feels unhappy only when finding himself poorer than his friends or relatives.　　So, a millionaire will experience a feeling of being lowered when confronting a billionaire, while a worker with a monthly salary of several hundred dollars becomes the envy of the villagers in remote mountainous regions.　　David Niven:　　True happiness is not a result from human action. Results are temporary whereas happiness is everywhere and can neither be created nor destroyed. True happiness is realized by understanding one’s own SELF. With true happiness there is no place for disappointments!　　True happiness may mean pain and restraint in the beginning but will lead to eternal joy and freedom. To achieve true happiness, we should isolate and remove the negatives.　　Joshua Patty:　　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 which is responsible for happiness.　　Laura Johnson:　　So what makes me a happy person? Studying to be a journalist because I love 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 that like the real me just as much as the old me. Being in a stable family. Reading romance novels and watching bizarre movies. Having a boyfriend who knows more about rock and roll history that I do.　　Now match the name of each person (1 to 5) to the appropriate statement.　　Note: there are two extra statements.　　Statements
