MR.S argues that the hacking i s a form of participation in the god's creation. people can see the open source hacker. Mr.S recognize the tensison but found them managible,not everyone argrees.Some disargement is pointed out. He is the lastest to link coding with the computer activities towards the creation and sharing. K believe the creation can go further in code. from the outside ,what the computer code be seen
大全错了三道题。把错误点发上来讨论 3. The passage suggests that during laboratory dives, the pH of the Weddell seal’s blood is not adversely affected by the production of lactic acid because (A) only those organs that are essential to the seal’s ability to navigate underwater revert to an anaerobic mechanism (B) the seal typically reverts to an anaerobic metabolism only at the very end of the dive (C) organs that revert to an anaerobic metabolism are temporarily isolated from the seal’s bloodstream (D) oxygen continues to be supplied to organs that clear lactic acid from the seal’s bloodstream (E) the seal remains submerged for only short periods of time 我选择的是D,答案是C， 判断点在此句：The latter results in the production of large amounts of lactic acid which can adversely affect the pH of the seal’s blood, but since the anaerobic metabolism occurs only in those tissues which have been isolated from the seal’s blood supply, the lactic acid is released into the seal’s blood only after the seal surfaces, when the lungs, liver , and other organs quickly clear the acid from the seal’s bloodstream. 分析了一下这句话的结构能得出c，但还是没明白when the lungs, liver , and other organs quickly clear the acid from the seal’s bloodstream.这个分句和主句有什么逻辑联系。
4. Which of the following best summarizes the main point of the passage? (A) Recent field studies have indicated that descriptions of the physiological behavior of the Weddell seal during laboratory dives are not applicable to its most typical dives in the wild. (B) The Weddell seal has developed a number of unique mechanisms that enable it to remain submerged at depths of up to 500 meters for up to 70 minutes. (C) The results of recent field studies have made it necessary for biologists to revise previous perceptions of how the Weddell seal behaves physiologically during its longest dives in the wild. (D) Biologists speculate that laboratory studies of the physiological behavior of seals during dives lasting more than twenty minutes would be more accurate if the seals were not forcibly submerged. (E) How the Weddell seal responds to oxygen deprivation during its longest dives appears to depend on whether the seal is searching for prey or avoiding predators during such dives. 我选的C，判断点是：Recent field studies, however, suggest that during more typical dives in the wild, this seal’s physiological behavior is different. 这是道主旨题吧，答案是A, 5. According to the author, which of the following is true of the laboratory studies mentioned in line 1? (A) They fail to explain how the seal is able to tolerate the increased production of lactic acid by organs that revert to an anaerobic metabolism during its longest dives in the wild. (B) They present an oversimplified account of mechanisms that the Weddell seal relies on during its longest dives in the wild. (C) They provide evidence that undermines the view that the Weddell seal relies on an anaerobic metabolism during its most typical dives in the wild. (D) They are based on the assumption that Weddell seals rarely spend more than twenty minutes underwater on a typical dive in the wild. (E) They provide an accurate account of the physiological behavior of Weddell seals during those dives in the wild in which they are either evading predators or exploring distant routes. 这道题直接就没搞明白，没选
