“What can a rock be? ‘Tall mountain / Park fountain / Dinosaur bone / Stepping-stone.’ The ideas expressed in this picture book’s pithy text are varied and wide-ranging. Each two-word phrase appears on its own page, accompanied by a luminous illustration. While some concepts will be obvious to children from the words alone, and others are made clear by the pictures, a few (‘Fire sparker,’ ‘Crusty dome,’ ‘Food grinder’) may need further explanation. The sometimes cryptic phrases create a natural guessing game, and an appended section offers a paragraph of text explaining each one. Moldovan illustrator Dabija contributes a series of dynamic full-page and double-page images created with traditional and digital media. Her compositions, color combinations, and use of light are particularly fine. Similar in concept to Salas and Dabija’s previous picture books, A Leaf Can Be . . . (2012) and Water Can Be . . . (2014), this beautiful picture book makes an excellent classroom read-aloud, challenging children to puzzle out the ideas in the poetic phrases and to broaden their thinking about rocks.” ―Booklist

“石头能是什么？高山/公园喷泉/恐龙骨头/踏脚石。这本图画书的精炼文字所表达的观点是多种多样的，涉及面很广。每个两个单词的短语都会出现在它自己的页面上，并附有一个明亮的插图。虽然有些概念对孩子们来说仅仅通过单词就可以理解，有些概念通过图片就可以理解，但是有些概念(“火焰喷射器”、“硬壳圆顶”、“食物研磨器”)可能需要进一步的解释。这些有时含义模糊的短语创造了一个自然的猜谜游戏，附加部分提供了一段文字解释每一个。摩尔多瓦插图画家 Dabija 贡献了一系列动态的全页和双页图像，这些图像是用传统和数字媒体创作的。她的构图、色彩组合和光线的运用都非常出色。与萨拉斯和达比加之前的图画书《叶子可以是… … (2012)》和《水可以是… … 》(2014)的概念相似，这本漂亮的图画书成为了一个优秀的课堂朗读，挑战孩子们在诗歌词组中拼出想法，拓宽他们对岩石的思考。”- 书目表
