  12.物质减缓全球变暖

  [v1]By nanyoua

  说一种由工厂排放的神马a物质能减缓全球变暖,因为能加速云的形成,阻挡阳光,而且这种云特别白,能反弹更多热量。但这种物质只在没有冰川覆盖的地方才能体现作用,冰川上不管用。中间balabala失忆中,最后说这种物质只能减缓变暖速度,无法消除变暖,因为一旦把工厂关闭,这种物质会快速消失,工厂排放其他东西会维持变暖趋势,不关工厂吧,虽然排放这种物质但同时也在排放其他气体。

  其余失忆中。。。

  aero什么的,可以cool 温度,但是它其实是mask greenhouse 而不是eliminate。有细节题和逻辑题。global warming 本身就是complicated。 一种由工厂排放的神马a物质能减缓全球变暖,因为能加速云的形成,阻挡阳光,而且这种云特别白,能反弹更多热量。但这种物质只在没有冰川覆盖的地方才能体现作用,冰川上不管用。【貌似出了逻辑题】中间balabala失忆中,最后说这种物质只能减缓变暖速度,无法消除变暖,因为一旦把工厂关闭,这种物质会快速消失,工厂排放其他东西会维持变暖趋势,不关工厂吧,虽然排放这种物质但同时也在排放其他气体。

  p1讲一种A什么什么的化学物质。A什么什么是由power house排放的,可降低温室效应。因为它会促进云的生成反射阳光。在一些观察到这种A什么什么排放增加的地区,冬天和晚上的温度虽然还是有上升,但是白天的温度没有上升一直维持constant甚至有下降。p2讲A什么什么的影响是复杂而且不稳定的,在海面上生成的云反射阳光效果好,在ice上生成的效果就不行了(这里一道题问为什么提到ice上的云),另外A什么什么还能够增加云反射阳光的能力。但是关于A什么什么的major concern还是它会增加温室效应而不是消除。因为power house一关,A什么什么就不会排放,而且效果迅速消失,但是carbon dioxide的效用会持续很久,于是就会继续变暖这样

  一开始说全球变暖模型与实际数据不符,有人提出是工厂排放的一种物质使得变暖减缓,有人质疑这种观点提出两个原因,后来又有人提出是因为北半球陆地为主,南半球海洋为主,所以南半球升温较为缓慢,那个人又提出另一种反驳说这种效应只是暂时的

  13.石雕的起源

  [V1]By sheng9056

  第一段,说在某个时间(地域?部族?楼主忘记了)有三个石雕(貌似)分别叫M,S,L。第二段,说一种这三个石雕的发展起源,第三段,考古发现之前这个说法是错误的。第四段,有个名字奇怪的专家说,其实M,S,L之间的关系是有两种(具体是哪两种忘记了)建立在另外一个上,然后那个时候的石雕家认为把石雕建立在以前的石雕上可以吸取力量(有题)。

  [V2]by bonnierong2010

  第三篇是石雕的起源(很长1屏半还要多)。第一段讲某些ethnic group从hunting转向agrculture,从而演变出了三种石雕M,S,L。一种理论认为三种石雕代表着不同的演变进程,现有M,然后是L,再是S。第二段对这种理论进行了however的转折评论,如果真是ethnic groups之间的转换的话,这些石雕应该被放在显眼的地方或者放在border,但是事实上这两个都没有发生(有题)。第三段讲某一个学者从另一个角度对石雕的演变进行了讨论,发现有些石雕如S和L出现在同一个石头上,并不是由于人们故意毁坏之前的石雕,而是由于当时人们认为两个石雕之间有某种联系(有题)

  14. 恐龙恒温or 变温

  [V1]By 华仔

  Para 1 有一个科学家在研究恐龙是恒温动物endotherm还是变温动物ectotherm,然后他通过恒温动物的的骨骼里通常都有abundant的经脉和组织等类似的东东,在动物幼年是就需要very active才能提供足够的能量去成长。而这个人在恐龙的fossil中发现了这种骨骼,然后就推定恐龙是恒温动物。

  Para 2 有另一个科学家反对上面这个观点。他通过另一个实验来证明他的观点。他把endotherm和ectotherm动物混合放到active的环境和quiet的环境中。发现在active环境中的动物都会发展出有abundant这些东东的骨骼,而在quiet的环境中的动画却没有发现有这个东东。因此,这个科学家反驳了上面的观点。

  [v2]By supersnake0731

  恐龙到底是cold-blood还是warm-blood的。第一段说一个学者P根据一个实验证明恐龙是冷血的,第二段另一个学者O做了一个实验反驳了他的观点,说他做的实验不能反映恐龙是冷血的(并没有反对说恐龙不是冷血的,只是说他这个实验不对)

  恐龙是否为恒温动物的。第一段一个人说由于XXX,所以恐龙是恒温动物。第二段来了另一个人,举了一些反证,说明第一人的观点错误。

  [V3]By Deeplus

  碰到了恐龙那篇。第一段,说有个A君发现有个什么B物质可以测出动物是热血动物。结果发现恐龙体内有B物质,所以它就是热血动物。

  第二段,说C君觉得A的发现就是一坨啊,因为他没考虑动物的运动程度,C做了个实验发现在动物运动程度剧烈的时候热血和冷血动物身体里都有B物质。

  [V4] xanderyang

  恐龙,这个清楚一点,说有一个科学家希望通过对新陈代谢METABOLISM的判断来推定恐龙是冷血还是暖血。他的理论基础是暖血生物新陈代谢频繁,组织的生长过程中新生长的骨头会嵌入肌肉血管组织里,然后骨头里面会生长出很多CANAL, CANAL 的多少可以判断他新陈代谢是不是平凡,所以他根据恐龙的化石中CANAL很多推定恐龙是暖血的。

  然后又一个科学家站出来了,这哥们做了一组实验,把冷些动物和暖血动物分成两组,其中每一组又分成两个SUBGROUP,一个是ACTIVE,一个是S打头的词(词不认识,应该是和ACTIVE相对应吧)。得出结论是ACTIVITY才是决定CANAL多少的因素,而不是新陈代谢,所以上一段那个哥们的结论没有任何意义。

  [V5]by lingqiang

  说恐龙恒温变温的 一个科学家分析恐龙的骨头发现一个什么物质 得出恐龙是恒温的(貌似) 然后第二段另一个人做了个实验, 来反对第一个科学家的观点。 拿恒温和变温的动物在相同的两种环境下实验,发现最后那个物质是取决与环境的。

  问题有第二段的细节题,还一个问第二个科学家是用什么方式反对第一个科学家的。

  补充:(很多人说这篇GWD像寂静,我就把它粘贴过来了)

  GWD-TN7-Q33-Q36

  Scientists studying the physiology of dinosaurs have long debated whether dinosaurs were warm- or cold-blooded. Those who suspect they were warm-blooded point out that dinosaur bone is generally fibro-lamellar in nature; because fibro-lamellar bone is formed quickly, the bone fibrils, or filaments, are laid down haphazardly. Consistent with their rapid growth rate, warm-blooded animals, such as birds and mammals, tend to produce fibro-lamellar bone, whereas reptiles, which are slow-growing and cold-blooded, generally produce bone in which fibrils are laid down parallel to each other. Moreover, like the bone of birds and mammals, dinosaur bone tends to be highly vascularized, or filled with blood vessels. These characteristics, first recognized in the 1930’s, were documented in the 1960’s by de Ricqlès, who found highly vascularized, fibro-lamellar bone in several groups of dinosaurs.

  In the 1970’s, Bakker cited these characteristics as evidence for the warm-bloodedness of dinosaurs. Although de Ricqlès urged caution, arguing for an intermediate type of dinosaur physiology, a generation of paleontologists has come to believe that dinosaur bone is mammalianlike. In the 1980’s, however, Bakker’s contention began to be questioned, as a number of scientists found growth rings in the bones of various dinosaurs that are much like those in modern reptiles. Bone growth in reptiles is periodic in nature, producing a series of concentric rings in the bone, not unlike the growth rings of a tree.

  Recently, Chinsamy investigated the bones of two dinosaurs from the early Jurassic period (208-187 million years ago), and found that these bones also had growth rings; however, they were also partially fibro-lamellar in nature. Chinsamy’s work raises a question central to the debate over dinosaur physiology: did dinosaurs form fibro-lamellar bone because of an innately high metabolic rate associated with warm-bloodedness or because of periods of unusually fast growth that occurred under favorable environmental conditions? (Although modern reptiles generally do not form fibro-lamellar bone, juvenile crocodiles raised under optimal environmental conditions do.) This question remains unanswered; indeed, taking all the evidence into account, one cannot make a definitive statement about dinosaur physiology on the basis of dinosaur bone. It may be that dinosaurs had an intermediate pattern of bone structure because their physiology was neither typically reptilian, mammalian, nor avian.

  GWD-9-Q33 G-9-Q33:

  The author of the passage would be most likely to agree that the “caution” (line 29) urged by de Ricqlès regarding claims about dinosaur physiology was

  A. unjustified by the evidence available to de Ricqlès

  B. unnecessary, given the work done by Bakker and his followers

  C. indicative of the prevailing scientific opinion at the time

  D. warranted, given certain subsequent findings of other scientists

  E. influential in the recent work of Chinsamy

  ----------------------------------------------------------------------

  GWD-9-Q34 G-9-Q34:

  The primary purpose of the passage is to

  A. discuss the influence on other scientists of Bakker’s argument concerning the warm-bloodedness of dinosaurs

  B. provide evidence that supports the claim that dinosaurs were cold-blooded

  C. challenge the contention that dinosaur bone tissue is innately fibro-lamellar

  D. evaluate the claim that dinosaur bone tissue provides evidence for the warmbloodedness of dinosaurs

  E. resolve the disagreement between de Ricqlès and Bakker over the nature of dinosaur physiology

  ----------------------------------------------------------------------

  GWD-9-Q35 G-9-Q35:

  According to the passage, the discovery of growth rings in the bones of certain dinosaurs served to undermine which of the following claims?

  A. That modern reptiles are related to dinosaurs

  B. That bone growth in dinosaurs was periodic in nature

  C. That dinosaurs were warm-blooded

  D. That dinosaurs had an intermediate type of physiology

  E. That fibro-lamellar bone is the product of a rapid growth rate

  ----------------------------------------------------------------------

  GWD-9-Q36 G-9-Q36:

  The author of the passage mentions bone growth patterns in juvenile crocodiles most likely in order to

  A. provide support for the argument that reptiles are not related to dinosaurs

  B. undermine the claim that most reptiles are slow-growing

  C. offer an explanation as to why juvenile crocodiles differ from most modern reptiles

  D. suggest the juvenile crocodiles have a type of physiology intermediate between-f mammals and that of reptiles suggest that the presence of fibro-lamellar bone does not resolve the debate over dinosaur physiology
