    Between now and then many changes will take place in this century. But what will the changes be? The

population is growing fast. There will be many people in the world and most of them will live longer than

people live now.

    Computers will be much smaller and more useful, and there will be at least one in every home. And

computer studies will be one of the important subjects in school then.

TV and travel. Traveling will be much cheaper and easier. And many more people will go to other countries

“老吾老,以及人之老;幼吾幼,以及人之幼”,“孝”是儒家伦理思想的核心。然而,近年频频爆出的关于“扶不起”(面对摔倒的路人,不肯、不敢上前搀扶等现象)种种负面新闻,人们开始怀疑我们这个社会是否正遭遇“道德寒冬”。面对这一窘境,需要大力宣传中华传统美德,加强舆论的正面引导作用;深入挖掘人们内心深处向善的因素,树立助人为乐的道德典范。并加强立法让哪些主动去“扶”去“助”之人的合法权益得到保护,使“扶得起”变成人人欲为的德行,实现由“不扶”到“扶”的变化。

结合材料,运用《文化生活》的有关知识,就如何“加强思想道德修养,追求更高的思想道德目标”谈谈你的看法?
