适读人群 ：4-8岁
These titles provide brief yet clear information on their respective topics. Day Light discusses the nature of light, darkness, and seeing, and the role heat plays in generating light. Floating in Space discusses how astronauts move and cope with weightlessness in space. Amusing illustrations, verbal and pictorial, demonstrate how gravity works. Children will find much of the information both entertaining and interesting, such as the way astronauts eat with magnetized trays that hold utensils in place. Full-color paintings illustrate the first title and softly colored cartoons enhance the latter. Both are worthy additions to collections that need science materials for early grades.

In this Let's-Read-and-Find-Out Science entry, Branley (see review, above) takes readers on a space shuttle mission, from blast-off to touchdown, but focusing mainly on life in orbit. As he points out, ``zero gravity'' is a misnomer--but only barely; so negligible is gravitational pull that astronauts temporarily grow an inch or so as their joints relax, are able to stand on the walls and ceiling, have to learn new ways to eat, sleep, and use the toilet, and must be very careful about stowing small objects before re-entry. In Kelley's cheerful watercolors, smiling space travelers--including one woman--bounce around the shuttle's cabin and suit up for extra vehicular tasks while back on Earth, a young girl eagerly tracks the flight on television. While in the claim that heavy equipment--even the 12-ton Hubble telescope--can be lifted in space, Branley oversimplifies the effects of inertia and momentum, his choice of detail about conditions in space will surprise and delight readers.

内容简介

Have you ever dreamed of being an astronaut? Wondered what it might be like to see the sun set sixteen times in one day?

Open this book and be transported on an information-packed voyage aboard the space shuttle. True Kelley's kid-friendly diagrams and illustrations and Franklyn Branley's straightforward text reveal what astronauts eat, how they move, and what kinds of work they do in space.

当当没有返券，所以他家100-20,200-50的活动就显得很不给力。不太指望他们家的618，话说这两天他们已经在暗自提价，一直在追的《汽车嘟嘟系列》已经从之前的7折涨到了81折，这书别的网站不是没货就是不全，当里个当的，只有他家有货又全却没折扣。题外话：像很多书，当哩个当的都做个39折活动，像小草怪还有过1折的时候（往往这个时候我都在犹豫……）包括小小牛顿我知道的最低的折扣有过37折，一次限时抢第二辑达到了29折，当时一向很贱的小爪子居然没有拍让我至今百思不得解；其余的像幼幼成长绘本、小鸡球球等都有过39折的时候，相信没有最低只有更低吧……
