commentary part1 Commentary The author's claim that American society has been silently disconnected ,and that we need to encourage participation among youth in order to create social capital. This claim has considerable merit with respect to education's function. However, while the claim that community is deteriorating may be justifiable in America, I tend to disagree when it comes to our own country. At first glance empirical evidence may lend credence to the author’s statement. As social media develops, we put more attention on electronic devices and less on real social intercourse.The urbanization process has led a mass migration from the countryside to the city, where people tend to live more independently from neighbours and relatives, and in smaller families. Furthermore, higher education seems to give people more ability and skills to think about and deal with things by themselves. All these might wither the bonds of social community. However, upon further reflection it is clear that educational and technological development as well as urbanization come along with social process. It is probable that every society has the same worry that people become more indifferent and disengaged, which may be only a fuss. For the unity and engagement might very well appear themselves in a new form.（from “however”:随社会发展，教育科技和城市化进程也会一起发展。每个社会都可能有同样的担忧，认为人们变得冷漠疏离，但这可能只是小题大做，因为团结和参与可能通过一种新的形势表现出来了。） Moreover, if we define a “connected” society broadly--in terms with tolerance of differing viewpoints and of those different from us, respect for individual rights, together efforts towards common goal, and cooperation across regional and cultural boundaries, then China’s society has progressed instead of regressed. We are becoming more sensitive to, and respectful of, the rights of women, various ethnic, racial and religious groups, homosexuals, and mentally-and physically-challenged individuals. The past year has seen an resolution to protect our natural environment by vehicle restrictions and the use of clean energy. Even from an international perspective, the expansion of cross-border trade and cooperative research against public health problems are proof that nowadays people are still as socialized as ever.

commentary part2 As for the solution to the problems cited in the essay, which our society is faced with to some degree, I also hold that education should be given priority. After all, education serves to instill in students a set of fundamental values, such as tolerance and respect, upon which the general mood of society is based. They can best be taught in schools where students can work their value systems out as they interact with their peers. Besides, values are caught as well as taught, so teachers of good character can contribute to this goal by acting as a role model. Finally, educational systems should develop more forms of participation and engagement among students, such as interest groups, student associations and volunteer work.（文章中说的问题，我们的社会也多少有一些，至于解决方法。。。毕竟教育提供一套价值观，而社会风气建立在这价值观上。。Besides...:此外，教育除了应该教授以外，也应潜移默化灌输给学生，所以，起到榜样作用的老师会有帮助。） In sum, while the essay may clearly articulate America’s pressing social ills, in China it seems to be an overstatement. Social disconnectedness coexists with social progress and is to some degree another form of social social capital. Besides, providing the young ability and principle of cooperation to promote social engagement by educational systems is a good choice.

to be happy I came across a paragraph going " In childhood we are happy to receive; it is the first opening of love. In youth we take and give, dedicate and possess – rapture and anguish are mingled, until parenthood brings a dedication that, TO BE HAPPY, must ask for no return. All these are new horizons of content, which the lust of holding, the enemy of love, slowly contaminates." What does the "TO BE HAPPY" mean here? Does this mean"If we want to be happy we must ask for no return" or mean"..a dedication that musk ask for no return,which I think is happy to us."? And,If you know a little Chinese, could you please help me to translate this sentence into Chinese？ Thanks!!
