【天气】这本书带孩子们穿越后院的四季变化，向他们展示一年中后院是如何变化的。夏天的时候，花儿是明亮的，一只小狗在绿草地上玩耍;在雪天里，我们看到一样的院子被雪覆盖着;在大风天，晒衣绳在微风中拍打着。孩子们还可以很有趣地指着我们在各种天气里穿的不同衣服的照片:手套、帽子、雨靴等等。

通过简单的方式讲述，并以明亮、简单、愉悦的插图为主题，你好，世界！让幼儿学习变得容易。而且每一页都给您与孩子提供了互动。这是把自然科学带给蹒跚学步孩子的完美方法，孩子的世界学无止境。

Weather takes children through the seasonal changes in a backyard, showing them how a yard changes throughout the year: on a summer day the flowers are bright and a puppy plays on the green lawn; on a snowy day we see the same yard blanketed with snow; on a windy day the clothesline flaps in the breeze. Children can also have fun pointing to pictures of the different clothing we wear in each type of weather: mittens, hats, rain boots, and more.

Told in an easy, friendly tone (“Look out the window. What is the weather like today?”) and featuring bright, cheerful illustrations, Hello, World! makes learning easy for young children. And each page offers helpful prompts for engaging with your child. It’s a perfect way to bring natural science into the busy world of a toddler, where learning never stops.
