  15. 树木分解有害气体

  By luciole(690)还有一篇感觉有点难,是研究树木对一种有害气体的分解作用,因为有一种物质还没分析出来,于是科学家猜想那个是有效降低两种废气的东西,但并未得到证实。

  By haoz0001一种理论说树木可以exhale一种气体H,在某种情况下或者一定温度下这种气体可以跟两种污染气体结合产生一种雾(haze). 好像还列举了一对其他因素。这种结合好像跟风也有关(忘记了是有影响还是没影响)。一个research对这种雾进行研究,发现haze的量要大于预期。所以得出结论,某些具有H相似功能的气体还未被发现。有问main idea,还有为了减少污染影响,haze形成,什么措施最没用。

  byansonchan(Q50 V44)第四篇是变态。。最后几题还剩11分钟的时候突然出来一篇一屏半的,我那时候都觉得要放弃了。是树木分解有害气体的那篇。非常难!一堆专业词汇……我没背词汇就直接冲og了。。所以看得不是很懂。但是有一点是大概清晰的。说什么一开始以为有害气体怎么怎么样了,但是后来科学家发现还有一些有害气体,没被发现的。后来用一个实验说明了这些unknown气体的存在(但是第二段我没细看了,没时间了)。第一题的题目就五行了,我那时候就要崩溃了~问你政府要怎么怎么样的话,以下哪种措施最不可行。

  bydemonj(760)应该是树木放射有毒气体。这篇真没咋看懂……到最后了有点慌……不过不长,大家镇定一下应该能看懂。第一题是问采取下面哪个措施来减少有毒气体影响会受到最小的作用。大家看的时候注意一下。 还有第二段里说decrease的速度比实际想象的要快,作者用了一个词an……来形容,问用这个词有什么用意

  bylovepiao第一段就是树的VONS这个东西~释放一种HD~举例比如I和T(都是不认识的单词)产生haze(这句没看懂,不知道是不是污染)~但是还有一些与VONS类似的物质没分析出来

  第二段是讲为什么怀疑有其他类似物质的存在。First因为与风向无关、Second因为I和T(就是第一段提的例子)I只能daytime怎么着~而HD是daytime和nighttime都可以~

  题目忘记了。。。~就记得有一道题题干巨长!看完我都疯了~先是介绍了某个情况没看懂。。~之后问下面哪项least usul to achieve the government&aposs proposal?A说限制排放那个HD~C貌似是说工厂怎么着~选项D是说患哮喘的人应该多呆在indoor~我瞎选的E就是和风向有关的选项

  题目基本相同,可能有变体

  T-9-20:GWD-13-34:

  Which of the following, if true, would most weaken the author’s conclusion in lines 25-30?

  A. New research reveals that the number of species of birds and parasites that prey on lepidoptera has dropped significantly in recent years.

  B. New experiments in which the habitats of lepidoptera are altered in previously untried ways result in the shortening of lepidoptera population cycles.

  C. Recent experiments have revealed that the nuclear polyhedrosis virus is present in a number of predators and parasites of lepidoptera.

  D. Differences among the habitats of lepidoptera species make it difficult to assess the fects of weather on lepidoptera population cycles.

  E. Viral disease is typically observed in a large proportion of the lepidoptera population.

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

  T-9-21:GWD-13-35:

  It can be inferred from the passage that the mortality caused by agents such as predatory birds or parasites was measured in an attempt to

  A. develop an explanation for the existence of lepidoptera population cycles

  B. identify behavioral factors in lepidoptera that affect survival rates

  C. identify possible methods for controlling lepidoptera population growth

  D. provide evidence that lepidoptera populations are self-regulating

  E. determine the life stages of lepidoptera at which mortality rates are highest

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

  T-9-22:GWD-13-36:

  The primary purpose of the passage is to

  A. describe the development of new techniques that may help to determine the driving force behind population cycles in Lepidoptera

  B. present evidence that rutes a particular theory about the driving force behind population cycles in Lepidoptera

  C. present a hypothesis about the driving force behind population cycles in Lepidoptera

  D. describe the fluctuating patterns of population cycles in Lepidoptera

  E. question the idea that a single driving force is behind population cycles in Lepidoptera

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

  T-9-23:GWD-13-37:

  According to the passage, bore the discovery of new techniques for detecting viral DNA, population ecologists believed that viral diseases

  A. were not widely prevalent among insect populations generally

  B. affected only the caterpillar life stage of lepidoptera

  C. were the driving force behind lepidoptera population cycles

  D. attacked already declining caterpillar populations

  E. infected birds and parasites that prey on various species of Lepidoptera

  by fydaydayup (700,Q51,V32)一种飞蛾,他们的数量有周期性的变化。但是一开始,科学家用常规的方法都没有测量出来引起周期性变化的原因,既不是生存地的条件,也不是捕食者的数量。后来科技发展,科学家发现应该是一种病毒。这个病毒会保存在一种晶体里面,晶体被飞蛾吃掉后,外壳就融化,然后病毒在飞蛾体内繁殖,同时包裹上晶体,等飞蛾死掉,那些晶体就落在土壤里了。然后这个发现很有意义,因为很多别的种类的飞蛾也可能是这个原因
