思想解放是社会进步的重要推动力,同时也是社会进步的必然结果。阅读下列材料,回答问题。

材料一:伏尔泰赞美孔丘“只诉诸道德,不宣传神怪”。他相信儒学是最好最合人类理性的哲学,并以中国为理想国,提倡以中国文化为标准。孟德斯鸠、卢梭则指出真实的中国根本不如尊孔人士想象和描述的那么美妙,他们对中国文化,尤其是无制衡的专制主义进行了猛烈的抨击和揭露。

——摘自庞忠甲《论儒学的国际影响》

材料二:16至17世纪的中国,新的经济形态还十分微弱、脆嫩,明清时期的早期启蒙思想家们先天不足,带有一种时代性的缺陷……黄宗羲、唐甄们提不出新的社会方案,而只能用扩大相权、限制君权、提倡学校议政等办法来修补封建专制制度。孟德斯鸠、卢梭们则拿出了“三权分立”、君主立宪制、民主共和制这样的资产阶级国家蓝图。这表明,中国明清时期的进步思想与18世纪欧洲启蒙思想属于两个不同的历史范畴。前者是中世纪末期的产物,后者是近代社会的宣言书。

——摘自张岱年、方克立主编《中国文化概论》

材料三:80年来,中国人从“师夷长技以制夷”开始,进而“中体西用“,进而自由平等博爱,进而民主和科学,在这个过程中,中国人认识世界同时又认识自身,其中每一步都伴随着古今中西新旧之争。高扬民主和科学之旗,包含着80年来中西文化论争所积累起来的认识成果,又体现了认识的一种飞跃,它由古今中西新旧之争而来,又是对古今中西新旧之争的历史概括。中国人因此而找到了一个最重要、最本质的是非标准,而后才可能有完全意义上的近代中国和近代中国人。

——摘自陈旭麓《近代中国社会的新陈代谢》

    Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you're never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though.

    Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand, are already part of a language community. Learning a new language means becoming part of another language community, and adults rarely get the chance to practice as much as young children do.

    Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel pressured to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language.

    When young children learn a new language, they come to see various languages as a “normal” part of society. This mindset (思维模式) helps them embrace learning a new language without feeling like they're doing something unusual or “too hard”.

    So if you want to learn a new language, go for it! It's never too late to learn a new language. If you're older, it may take more work, but it can be done. If you're a young child, though, now is the time to step out and learn a new language!
