下面的短文有5处空白，短文后面有6个句子，其中5个取自短文，请根据短文内容将其分别放回原有位置，以恢复文章原貌。Stars in Their EyesThe Scientific American Book of the Cosmos edited by David Levy， Macmillan， ￡20， ISBN 0333782933Previous generations of seientists would have killed to know what we know. For the first time in history， we have a pretty good idea of the material content of the Universe， our position within it and how the whole thing came into being.In these times of exploding knowledge there is a definite need to take stock and assemble what we know in a palatable （受欢迎的） form_________（46）The essays in The Scientific American Book of the Cosmos have been selected by David Levy，co-discoverer of Comet Shoemaker-Levy 9， which in 1994 struck Jupiter with the violenee of several full-scale nuclear wars. _________（47） This is certainly a great collection of essays， but it is not， as the book promises， a seamless （完美的，无缝隙的） synthesis of our current knowledge.Nobody can fault the range of articles Levy has included. There are essays on the planets，moons and assorted debris （碎片） in the Solar System， and on our Galaxy， the Milky Way. _________（48）The contributors， too， are stars in their own fields. Not many books can boast eha'pters written by such giants as Erwin Sehrodinger and Francis Crick. My personal favorites are a piercingly clear essay by Albert Einstein on general relativity and an article by Alan Guth and Paul Stein- hardt on the inflationary （膨胀的） Universe.So much for the book's content. But Levy has not succeeded in providing an accurate synthe-sis of our current knowledge of the eosmos， which the book jacket promises. Gathering together previously published articles inevitably leaves subject gaps， missing explanations and so on._________ （49） But there isn't one. In fact， surprisingly for a book so densely packed with infor-mation， there is no index.Collecting essays in this way is clearly a good publishing wheeze （巧妙的注意）. But this approach shortchanges the public， who would be better served by an account moulded into a seamless whole._________（50） However， for the next edition， please， please can we have an index?46 查看材料
