高考语文基础知识模拟组合训练与答案解析17 一、基础知识(9分) 阅读下面的文字，完成1～3题。 以《中国诗词大会》和《朗读者》为代表，央视文化节目如________，成为文化综艺新的标杆。但由于跟风，“诗词”和“朗读”严重扎堆，渐渐使人审美疲劳。“在文学等细分题材被集体消费的时候，我们要着眼未来，探索新的方向。”央视副总编辑朱彤承诺，“央视将持续在原创文化节目上发力。”而总导演、制片人于蕾给《国家宝藏》下了定义——“大型文博探索节目”：历史文化的内核、综艺的外壳、纪录的气质，创造了一种集演播室综艺、纪录片、舞台戏剧、真人秀等多种艺术形态于一体的全新模式，是全新创制的“纪录式综艺”。 其实，博物院文化的流行早有端倪，《我在故宫修文物》的纪录片也曾________。在这样的背景下，《国家宝藏》播出的时机，无疑是非常合适的。说起博物馆，总让人想起深宫大院；说起文物，也总让人想到冰冷的历史，它们仿佛离我们日常的生活很远。而《国家宝藏》之所以能够________，是因为它使那些尘封于历史的文物活了过来——请来能辐射到各个年龄阶层的演员，又在表演的各个方面精准要求演员，( )。它们不再是冰冷的，而是带着温度的。不但记载着厚重的历史、灿烂的文化，也与我们许多人的生命________。 1．依次填入文章横线上的成语，全都恰当的一项是(3分)() A．比比皆是盛极一时脱颖而出休戚相关 B．雨后春笋风靡一时红极一时息息相关 C．比比皆是风靡一时红极一时休戚相关 D．雨后春笋盛极一时脱颖而出息息相关 [解析] “雨后春笋”，指新生事物大量出现。“比比皆是”，到处都是，非常常见。根据语境，应用“雨后春笋”，可排除A、C两项。“风靡一时”，形容一种事物在一个时期内极为流传盛行。“盛极一时”，在一段时间内特别兴盛、流行。二者为近义成语，均符合语境。“红极一时”，指在一段时间内受人追捧。“脱颖而出”，比喻人的本领全部显示出来。“脱颖而出”使用对象为人，此处说的是《国家宝藏》，排除A、D两项。“休戚相关”，彼此间福祸相关联。“息息相关”，呼吸相关联，形容关系密切，此处不涉及“祸福”，排除A、C两项。故选B。 [答案] B 2．文中画横线的部分有语病，下列修改最恰当的一项是(3分)() A．“大型文博探索节目”以历史文化的内核、综艺的外壳、纪录的气质，创造了一种集演播室综艺、纪录片、舞台戏剧、真人秀等多种艺术形态于一体，是全新创制的“纪录式综艺”。 B．“大型文博探索节目”以历史文化的内核、综艺的外壳、纪录的气质，创造了一种集演播室综艺、纪录片、舞台戏剧、真人秀等多种艺术形态于一体的全新模式，是全新创制的。 C．“大型文博探索节目”历史文化的内核、综艺的外壳、纪录的气质，创造了一种集演播室综艺、纪录片、舞台戏剧、真人秀等多种艺术形态于一体的全新模式，是全新创制的“纪录式综艺”。
