中华文化源远流长，博大精深，为人类文明的发展做出了重要贡献。阅读材料，回答问题。材料一  伏尔泰对孔子的思想极为推崇，“孔子”成为他敢于反抗专制的“守护神”。他把孔子的思想概括自“德治主义”，坚定地主张法国应该实行“德治主义”。

（1）据材料一，“德治主义”体现了孔子思想的核心是什么？伏尔泰为什么推崇孔子思想？

材料二  东亚国家大量吸收中国文化，是在唐室中衰以后，自此可见，中国文化的价值并非完全依附国力对外传播。一些东亚国家把唐代的经书作为士大夫的必读书，其典章制度几乎完全由中国移植而去，城市的格局也仿照长安的市坊制建立。

                                                                                                                                                                             ——《孔子思想对世界文化的影响》

    ——《东亚文化圈》

（2）据材料二，“中国文化的价值并非完全依附国力对外传播”说明了什么？概括指出唐代文化对东亚国家产生的影响。

材料三  如果想看看各种发明的力量、作用，最显著的例子就是新近发明的印刷术、火药和指南针。因为这三种东西改变了整个世界的面貌。第一种在文学上，第二种在战争中，第三种在航海上。

                                                                                                                                                                               ——培根

（3）据材料三，分别指出“这三种东西”怎样“改变了整个世界的面貌”？

    Author Elizabeth Becker says we have a responsibility to respect the places we visit. Some basic rules still hold, such as not travelling at busy times and taking fewer trips but making them longer. The best and easiest way to be a responsible traveler is to use common sense and go local.

    Respect traditions. Read about the culture and traditions of the places you visit. Understand the local culture and customs to avoid making any mistakes or upsetting the local people. For example, dress properly when you visit temples and don’t eat or talk loudly in religious(宗教的)sites. It’s also important to respect the local environment. If you visit a beach, leave seashells where you find them and try not to catch fish while swimming.

    Learn the language. Nobody expects you to become fluent, but try to learn some basic phrases such as “please” and “thank you”. You’ll be amazed at how much nicer and more helpful people will be if they know you’re making an effort to get involved with their culture.

    Spend local. Stay away from international hotels and restaurants run by foreigners. By using local guides, buying local products and staying in family run hotels, you’re not only giving back to the community, but you also get a real sense of the country you’re staying in and the people who live there.

    Bargain fairly. Always be polite when you try to get a lower price. Sometimes goods at a local market can seem overpriced. Nobody likes to be cheated and it may be fun to bargain, but remember that for the local people bargaining it may not be a game. For some of them, their business is their only source of income. So try not to be too rude when bargaining.

    Don’t litter. In some countries, getting rid of waste is a big problem, so don’t throw rubbish on the ground. Doing so is harmful to the environment and unpleasant for others. Hold on to your rubbish until you find a bin.

    Save water. Even in some of the most developed countries, water shortages are a reality. Tourists who take 10-minute showers and leave the taps running aren’t making things any better.
