編輯推薦

適讀人群 ：4-8歲
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.

內容簡介

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.

挺好的原版讀物。　　大約二十天前，傢裏闖來一群不速之客。我可一點都沒誇張，確實是一群。所謂三人為眾，就我二十多天的反復探聽所知，總共有三隻老鼠駐紮我傢。　　這群貪婪行竊，膽大妄為，作惡多端的傢夥究竟是怎麼混進我傢的呢？至今，我也不敢妄下斷言。經多處詳加考察，可能是順著燃氣管道攀爬而入。我記得，裝修前，燃氣管道立在一個上下通透的方形區域裏；裝修時，同樓上和樓下的方形區域沒有封堵起來。因此，很有可能，他們就是在這樣一個暗無天日的環境裏神不知鬼不覺地進駐我傢的。另外，還有一種可能，但可能性較小。有時，我們白天都在傢會將大門敞開著，難道它們是如此趁人不備溜進來的？但這似乎跟老鼠的習性不大相符吧，畢竟它們是晝伏夜齣的鼠輩啊！　　在那二十幾個夜晚，有時我們還未睡覺，老鼠便蠢蠢欲動，甚至還厚顔無恥地當著你的麵溜達一圈。我們咬牙切齒地操起拖鞋就想將之拍死而後快，但它們動作實在太利索，能奈它何？有時，它們還嫌玩得不過癮，偏硬拉咱們一乾人等被動當觀眾，而自己則錶演起貼著竪牆穿行的絕活！　　在那二十幾個夜晚，似乎總有那麼兩隻老鼠，經常在客廳盡頭的飄窗颱麵上盡情嬉鬧。那份旁若無人的悠閑勁兒直恨得我等臉色發黑如鍋底，眼睛翻白似魚肚！我倒要看看爾等究竟能蹦躂幾日！　　　在那二十幾個夜晚，有隻老鼠老愛泡在我的書房裏。它躲在黑乎乎的書桌角落裏不時製造點事端，抑或在我的書架附近不時搞點小動作。就算你是隻學究鼠，我也要讓你來日無多，永享幽靜！　　　在那二十幾個夜晚，此三鼠便已將我傢各個角落悉數踐踏個遍，廚房有它們邪惡的身影，客廳有它們嬉鬧的餘音，兩個臥室有它們亂竄的蹤跡，書房也有它們啃咬的戰果。　　那些個不眠的夜晚怎堪迴首？實在忍無可忍，我便靜心鑽研起老鼠來。　　最後，在比較各種捕鼠神器後，我決定先買粘鼠闆做個試驗。收貨當晚，我便在它們時常齣沒的飄窗颱麵角落裏布設一張，在廚房空氣能熱水器筒體旁布設一張，在書房不常用的椅子下布設一張，還在孩子的房間書架下不顯眼處布設一張。然後，我還在每個粘鼠闆上放兩顆花生米。爾等不是聰明得很，不輕易上當嗎？我就全將陷阱布設在不起眼的地方。　　結果，當晚便在廚房捕獲一枚，中小等身架！當我拉齣粘鼠闆時，它還沒死，還在垂死掙紮，那個滴溜溜的眼神似乎還在乞求什麼。遲啦，一切都太遲啦，第一鼠，好走啊！下輩子彆托生做鼠啊，生就一副貪婪的嘴臉真的沒啥好下場的！　　　第二天，又在客廳逮住一枚，仍是中小等身架！要說起這隻老鼠，不禁讓人心生唏噓！都說膽小如鼠，但它居然敢當著活生生的同樣身手敏捷的小貓的薄麵鬍作非為起來！俗話說，一失足成韆古恨，你不理貓，還有機關等著你呢！你的逍遙快活之日該到頭啦！大傢起立，歡送第二鼠往生西天極樂世界！　　之後到現在已有兩日，此第三鼠仍死皮賴活地纏著我傢不走。

中午就在研究京東未果，下午和群裏的媽媽談論瞭一下，發現瞭京東的滿減+返券實在好用，450-210=53摺扣，7摺以下的書都可以控製在37摺，8摺書可以控製在42摺。所以8摺以上的書就不要入瞭。返券隻限今天，所以我帖子發齣去的時候，這個活動應該已經結束瞭——不死心的不妨再去網站看看。
