To get a hand in is to begin a job, to begin to know something about it. When we learned completely, it will be easy for us. We will be able to do it hands down. If we do the job well, we may end up with the upper hand. That means to be in control or to have gained complete understanding of a situation. On the other hand, if the situation gets out of hand then, it is out of control. Then we may have to hand it to someone, to let someone else take over the business. It is time for us to wash our hands, to end it up completely. You can also lend a hand to someone but without really giving up your hand. You lend a hand when you help someone. You offer them a helping hand. If someone is kind enough to lend us a hand then we surely do not want to bite the hand that feeds us. We do not want to repay his kindness by treating him badly. The expression "to end up with the upper hand" means ______. A．to begin a job B．to be in control C．to be out of control D．to take over the business

As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment (承担的义务), self-improvement. Ask a bachelor (单身汉) why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features. Couples with infant children are lucky to get a whole night’s sleep or a three-day vacation. I don’t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all. 第31题：According to the author, a bachelor resists marriage chiefly because ________. A) he is reluctant to take on family responsibilities B) he believes that life will be more cheerful if he remains single C) he finds more fun in dating than in marriage D) he fears it will put an end to all his fun adventure and excitement
