【正文】 to do with the way milk39。m sure thereis more study on the shouldn39。t have a... P: You know,thereis a dairy not far from here in Chelsea. Itwas one of the first diaries to bottle milk in opaque plastic, but now they39。s exactlywhat he intended to do: create realistic moving scenes that change before the audiences39。t we say that the Eidophusikon actually influenced the painters? At theveryleast we have to consider thatit wasmore ...it was more ofa mutual thing. We know,for example, that theimportant English landscape painter Thomas Gainsborough attended almost all of theyearly performances, and his laterpaintings are notable for their increased color and dynamic use of light. Loutherbourg39。 mechanical figures, such as cattle, moved across the scene,and ships sailed along the what really got people was the attention to detail, much like his work in DruryLane. So, for example,he painted very realistic ships, and varied their size depending on theirdistance from the audience. Small boats moved more quickly across the foreground than larger ones did that were closer to the horizon. Othereffects, like waves, werealso veryconvincing. Theyreflected sunlight or moonlight depending on the time ofday or night. Even the colorschanged as theywould in nature. Sound and light were important in ** his productions realistic. Heused a greatnumber oflights, and he was able to change colors of light by using variously colored piecesof glass, to createeffectslike passing clouds that suddenly change in color. Furthermore,he used effects tomake patterns of shadow and light, rather than 全國(guó)免費(fèi)咨詢電話： 4000123267 using the uniform lighting that was mon at thetime. And many of the sound effectshe pioneered are still in use today,like creating thunder by pulling on one of the cornersofa thin copper of his most popular sceneswas of a storm. And there is a storythat on one occasion, an actual storm passed over head during the some people wentoutside, and theyclaimed Loutherbourg39。snot much precipitation. And because of the cold temperatures, the tundra has two layers: top layer,which is called the active layer,is frozen in thewinter and spring, but thawsin the summer. Beneaththis active layer is the second layer called permafrost,which is frozenall year around, and is impermeable towater. Female Student: So because of thepermafrost, none ofthe plants that grow therecan have deep roots, can they? 全國(guó)免費(fèi)咨詢電話： 4000123267 Lecturer:No, and that39。t interfere with their ? Now since the temperatureshave been increasing in Arctic Alaska, thegrowth ofshrubs has increased. And thisis presented toclimate scientists with a puzzle... Male Student: I39。retwo reasons for this: first, theylive in the active layer,which, remember,containswater that doesn39。s responsible for thegrowth ofshrubs in the summer and their spread tonew areasof the tundra. Areaswith more new nutrients arethe areas with the largest increase in shrubs. Female student: But,what about runoff in the spring, when thesnow finally melts? Won39。s caught by shrubs. And deep snow drifts often form around shrubs. And we39。lldo do you need? S: Well, I39。m writing my senior thesis, I39。s returned in a couple ofweeks. S: But I reallyneed this book right now. L: Do you needall of it or is therea certain section or chapteryou39。re working on right now? And by the timeyou need the rest ofthe book, maybe it will have been returned. We can even do the photocopy for you because of thecircumstances. S: Oh, well, that would be great. L: Isee you39。t returned books. They39。t want to waste anytime getting it back. S: Thanks a lot. Now I don39。vebeen times in the past when monsoon rains soaked the EmptyQuarter and turned it from a desert into grassland that was dotted with lakesand home to various animals. Therewere 全國(guó)免費(fèi)咨詢電話： 4000123267 actually two periods ofrain and lake formation: thefirst one began about 35000 yearsago。s past. Keepin mind though that this studyonly looked at 19 formations. And about a thousand have been there39。re up to a kilometer long, but only a few meterswide, and they39。d expectto find fossils from a variety of animals, and numerous fossils have been found at least at theseparticular 全國(guó)免費(fèi)咨詢電話： 4000123267 sites. But,where did these animals e from? Well, thetheorythat has been suggested is that theymigrated in from nearby habitats wheretheywere already living. Then as thelakes dried up, theydied study makesa couple of interesting points about the fossils, which I hope will be looked at in future studies. At older lake sites, their fossil remains from hippopotamuses,waterbuffalo, animals that spend much of their lives standing in water,and also, fossils ,at the sitesof themore recent lakes, there’re only cattlefossils, additional evidencefor geologists that these lakeswere probably smaller, sh
