单选题 孝顺不应当被规定实行 New standards of filial piety released by the Chinese government specifying 24 requirements for dutiful children have triggered a heated discussion. The new standards include spending holidays with parents, visiting them regularly, calling them once a week, and cooking for them. Should filial piety be regulated? What's your opinion? Read carefully the opinions from both sides and write your response in about 200 words, in which you should first summarize briefly the opinions from both sides and give your view on the issue. Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks. YES Putting forward the filial piety standards aims to promote the traditional Chinese virtue of respecting the elderly. China has a long history of valuing filial piety, which forms the core of family values. Compared with the traditional filial devotion, the new standards are more up to date and relevant to modem society. The new standards are an innovative way of inheriting the essence of filial culture. The modem society lays great stress on the legal regulation, while filial piety which depends on people's moral sense and inner discipline seems unable to prevail. What we need now is a code of conduct that helps to persuade people to practice filial piety. These standards do not intend to force people to obey filial principles by law, but provide them with a guideline. NO As a moral requirement for human beings, filial piety is unlikely to have perfect standards. Real filial piety is not something to be shown off to others, but something buried deeply in one's heart. Due to different living and working environments, the ways of practicing filial piety may be different. It is unwise to require every child to follow the same standards. Besides, the new standards are not feasible in modem days as many people live far away from their parents and have little time outside of work. The implementation of these new filial piety standards is not the right solution to the problem of China's aging population. As for the government, it is more effective to build up more state-ran nursing homes rather than issue filial piety standards in order to solve the problem.

They 42 needed supplies of highly trained personnel to 43 a concept of development based on modernization. But many of these students decided to stay on in the developed countries when they had finished their training. In the 1960s, some Latin American countries tried to solve this problem by setting up special 'return' programs to encourage their professionals to come back home. These programs received support from international bodies such as the International Organization for Migration, which in 1974 enabled over 1, 600 44 scientists and technicians to return to Latin America. In the 1980s and 1990s, 'temporary return' programs were set up in order to make the best use of trained personnel 45 strategic positions in the developed countries. This gave rise to the United Nations Development Program's Transfer of Knowledge through Expatriate Nationals, which encourages technicians and scientists to work in their own countries for short periods. But the brain drain from these countries may well increase in 46 to the new laws of the international market in knowledge. Recent studies 47 that the most developed countries are going to need more and more highly qualified professionals around twice as many as their educational systems will be able to produce, or so it is thought. As a 48 there is an urgent need for developing countries which send students abroad to give 49 to fields where they need competent people to give muscle to their own institutions, instead of encouraging the training of people who may not come back because there are no professional outlets for them. And the countries of the South must not be content with institutional structures that simply take back professionals sent abroad; they must introduce 50 administrative procedures to encourage them to return. If they do not do this, the brain drain is 51 to continue.

Are you afraid to ask someone for a date? Many people are afraid to assert themselves. Dr. Alberti thinks it's because their self-respect is low. 'Our whole 43 is designed to make people distrust themselves,' says Alberti. 'There's always ' 44 ' around—a parent, a teacher, a boss—who 'knows better'. These superiors often gain when they chip away at your self-image.' But Alberti and other scientists are doing something to help people 45 themselves, They 46 'assertiveness training' courses—AT for short. In the AT courses people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be more 47 without hurting other people. In one way, learning to speak out is to 48 fear. A group taking a course will help the timid person to lose his fear. But AT uses an even stronger 49 —the need to share. The timid person speaks out in the group because he wants to tell how he feels. Whether or not you speak up for yourself depends on your self-image. lf someone you face is more 'important' than you, you may feel less of a person. You start to 50 your own good sense. You go by the other person's 51 . But, why should you? AT says you can get to feel good about yourself. And once you do, you can learn to speak out.
