题目内容
13．People praise the cave as"Art Palace of Nature"．（改为被动语态）The caveispraisedas"Art Palace of Nature"..
分析 --人们称赞芦笛岩为"自然的艺术殿堂"．
--芦笛岩被人们称赞为"自然的艺术殿堂"．
解答 答案：is praised．考查被动语态．句意"--人们称赞芦笛岩为"自然的艺术殿堂"．--芦笛岩被人们称赞为"自然的艺术殿堂"．"．被动语态表示动作的承受者，结构是：be动词+动词的过去分词．cave是单数，根据praise可知，是一般现在时态，因此用be动词单数is．praise的过去分词是praised．答案是is praised．被称赞．
点评 被动语态表示主语是动作的承受者，被动语态由"be动词+及物动词的过去分词"构成，be动词的单复数要与主语的单复数保持一致，还要注意时态及过去分词的变法．
