Because conflict and disagreements are part of all close relationships, couples need to learn strategies for managing conflict in a healthy and constructive way. Some couples just__50__ and deny the presence of any conflict in a relationship. __51__ ,denying the existence of conflict results in couples _52___ to solve their problems at early__53__ ,which can then lead to even greater problems later on .Not surprisingly, expressing anger and disagreement leads to lower marital (婚姻的)satisfaction at the beginning. However, this pattern of behavior _54___ increases in marital satisfaction over time. Research suggests that working through conflicts is an important predictor of marital satisfaction.
　　So, what can you do to manage conflict in your own relationships? First, try to understand the other person’s point of view__55__ put yourself in his of her place. People who are _56___ to what their partner thinks and feels _57___ greater relationship satisfaction. For example, researchers found that among people in dating relationships  58____ marriages, those who can adopt their partner’s perspective show more positive emotions, more relationship-enhancing attributes and more constructive responses _59___ conflict.
　　Second, because conflict and disagreements are an __60__ part of close relationships，people need to be able to apologize to their partner for wrongdoing and __61__ forgiveness from their partners for their own acts. Apologies minimize conflict, lead to forgiveness, and serve to restore relationship closeness. In line with this view, spouses（配偶） who are more forgiving show higher mental quality over time. Increasingly, apologizing can even have _62___ health benefits. For example, when people reflect on hurtful __63__ and grudges(怨恨)，they show negative physiological(生理的) effects, including __64__  heart rate and blood pressure, compared to when they reflect on sympathetic perspective-taking and forgiving.

C
　Being considered a leader in our society is indeed of high praise. Leadership means power, commands, respect and, most important, encourages achievement. Unlike vitamin C, leadership skills can’t be easily swallowed down. They must be carefully cultivated.
　Different from popular belief, most good leaders are made, not born. They learn their skills in their everyday lives. But which do they develop？How do they (and how can you) get others to follow?
　Always give credit. Many leaders note that the most efficient way to get a good performance from others is to treat them like heroes. Giving public credit to someone who has earned it is the best leadership technique in the world. It is also an act of generosity (慷慨) that’s never forgotten.
　Giving credit is more effective than even the most constructive criticism (批评), which often hurts rather than helps. Kenneth Blanchard, the author of The One-Minute Manager, agrees. “Catch people doing something right!” he says. Then tell everyone about it.
　Take informed risks. “The best leaders know that taking a risk is not a thoughtless exercise,” says management adviser Marilyn Machlowitz. “Sky divers don’t go up in an airplane without checking the parachutes (降落伞) beforehand.”
　Because the idea of risk also carries with it the possibility of failure, many of us usually wait for others to take charge. But if you want to be a leader, you must learn to fail and not die a thousand deaths. Pick yourself up and start all over again.
　Encourage enthusiasm (热情). “When people understand the important of work, they lend their mental strengths,” says Lee Ducat. But when they get excited about the work, all their energy gets poured into the job. That’s a great force! Is this the best way to create excitement? Be enthusiastic yourself. You will be followed by everyone.
64．The underlined word “cultivated” (in paragraph1) roughly means ________.
A．encouraged　　　　B．compared　　 C．examined　　　　D．developed
65．The part “always give credit” tells us that a leader should _______.
A．give helpful criticism　　　　　　　     B．regard others as real heroes
C．praise people for their good performances　  D．praise everyone
66．To be a good leader, you should _______.
A．not be afraid of any risks　　　　　　     B．think twice before taking risks
C．try to avoid any possible failures　　　　    D．know what a thoughtless exercise is
67．Which of the following can be the best title for the passage?
A．Leadership is of skills and techniques　　     B．Leadership is very important
C．Not many can be leaders　　　　　　     D．How to be a leader
