SECTION B PASSAGESDirections: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.听力原文: A good marriage means growing as a couple but also growing as individuals. This isn't easy; marriage has always been difficult. Why then are we seeing so many divorces at this time? Yes, our modem social fabric is thin, and yes, the permissiveness of society has created unrealistic expectations and throw the family into disorder. But divorce is so common because people today are unwilling to exercise the self-discipline that marriage requires. They expect easy joy, like the entertainment on TV, the thrill of a good party. Marriage takes some kind of sacrifice, not dreadful self - sacrifice of the soul, but some level of compromise. Some of one's fantasies, some of one's legitimate desires, have to be given up for the value of the marriage itself. 'While all martial partners feel shacked at times, it is they who really choose to make the martial ties into confining chains or supporting bonds,' says Dr. Walter. Marriage requires sexual, financial and emotional disciple. A man and a woman cannot follow every impulse, cannot allow them to stop growing or changing.Why are divorces so common at present?A.Because it is difficult to maintain a marriage.B.Because people like watching TV programs.C.Because people prefer freedom to self - discipline.D.Because our society is permissive towards divorces.
