Did a Dinosaur Drink This Water? (award-winning)妙想科学：恐龙喝的水和今天的一样吗？ISBN9780807588406

　　Wells, who explored topics such as large numbers in Can You Count to a Googol (2000) and the measurement of time in How Do You Know What Time It Is?(2002), now tackles the water cycle, explaining that the earth's water has been constantly recycled not just since dinosaur days but for billions of years. The simple text asks good questions and offers clearly worded answers, enhanced by lively, colorful ink-and-watercolor illustrations. In the pictures, two children travel in a helicopter-like gizmo all around the world, observing streams, rivers, oceans, rain, snow, glaciers, a dam, and so on. Readers will also see illustrations of evaporation and underground aquifers. The text ends with a plea for water conservation. A playful but sound introduction to the water cycle. Carolyn Phelan

　　Robert E. Wells (Robert Ernest Wells) was born in Pasadena, CA in 1940. In the 90s, he began to put words and pictures into the form of children's books, and now in the new century he continues to do so. In 1993 he wrote and illustrated his first book,“Is a Blue Whale the Biggest Thing There is?”. Other books include “What's Smaller Than a Pygmy Shrew?” (Outstanding Science Trade Book for Children, 1996), “What's Faster Than a Speeding Cheetah?”, and his latest book, “Why Do Elephants Need the Sun?”. Many of his books have been translated into various other languages.
