今年春节前后,由央视著名主持人董卿担纲的《中国诗词大会》和《朗读者》成为文化类综艺节目爆款,和《百家讲坛》、汉字听写大会、成语大会等文化盛宴,被誉为“综艺文化清流”。阅读材料,回答问题。

材料一:《中国诗词大会》是央视首档全民参与的诗词节目,节目以“赏中华诗词、寻文化基因、品生活之美”为基本宗旨,力求通过对诗词知识的比拼及赏析,带动全民重温那些曾经学过的古诗词,分享诗词之美,感受诗词之趣,从古人的智慧和情怀中汲取营养,涵养心灵。借古诗词学霸爆红的契机,教育人士期待能在全社会的努力下,改变古诗词整体教育氛围——未来能减少孩子“苦恼”背书,而是能够惬意感受和品味古诗词之美。当喧嚣的现代社会与传统文化有了一次次美丽的“邂逅”,中华文化基因逐渐苏醒,这危机中的微熹,则弥足珍贵。

材料二:《朗读者》第一期压轴出场的是96岁高龄的著名翻译家许渊冲先生,他在国内外出版译著包括《诗经》、《楚辞》、《李白诗选》、《西厢记》、《红与黑》、《包法利夫人》、《追忆似水年华》等六十本,是有史以来将中国历代诗词译成英、法韵文的唯一专家。2014年8月2日许渊冲获得国际翻译联盟(国际译联)2014“北极光”杰出文学翻译奖,成为该奖项自1999年设立以来首位获此殊荣的亚洲翻译家。许老先生尽毕生之力所做的,就是向世界传播中国文化之美,似无止境。对于未来的时间,他是这样设计的:两个多月翻译一本,计划有生之年完成《莎士比亚全集》。

    Hundreds of years ago, news was carried from place to place by people on foot or by horse. It took days, weeks and sometimes months for people to receive news. Now it is possible to send words and pictures around the world in seconds(秒). Billions of people learn about news stories of their own country and all over the world every day, either by watching TV or reading newspapers. Newspapers have been an important part of everyday life since the 18th century. Many countries have hundreds of different newspapers. How do newspaper editors(编辑) decide which news stories to print (印刷)? Why do they print some stories and not others? What makes a good newspaper story?

    Firstly, it is important to report new stories. TV stations can report news much faster than newspapers. Yet, newspapers give more about the same story. They may also look at the story in another way, or they may print completely (完全地) different stories to those on TV.

    Secondly, a news story has to be interesting and unusual. People don't want to read stories about everyday life As a result, many stories are about some kind of danger and seem to be "bad" news. For example, newspapers never print stories about planes landing safely, instead they print stories about plane accidents.

    Another factor(因素) is also very important in many news stories. Many people are interested in news in foreign countries, but more prefer to read stories about people, places and events (事件) in their own country. So the stories on the front page in Chinese newspapers are usually very different from the ones in British, French and American newspapers.
