  P3

  The great variety of plants in Hawaii is a result of the long-distance dispersal of seeds. There is some dispute about the method of transport involved. Some biologists argue that ocean and air currents are responsible for the transport of plant seeds to Hawaii. Yet the results of flotation experiments and the low temperatures of air currents cast doubt on these hypotheses. More probable is bird transport, either externally, by accidental attachment of the seeds to feathers, or internally, by the swallowing of fruit and subsequent excretion of the seeds. While it is likely that fewer varieties of plant seeds have reached Hawaii externally than internally, more varieties are known to be adapted to external than to internal transport. (119 words)

  6. The author of the passage is primarily concerned with

  (A) discussing different approaches biologists have taken to testing theories about the distribution of plants in Hawaii

  (B) discussing different theories about the transport of plant seeds to Hawaii

  (C) discussing the extent to which air currents are responsible for the dispersal of plant seeds to Hawaii

  (D) resolving a dispute about the adaptability of plant seeds to bird transport

  (E) resolving a dispute about the ability of birds to carry plant seeds long distances

  7. The author mentions the results of flotation experiments on plant seeds most probably in order to

  (A) support the claim that the distribution of plants in Hawaii is the result of the long-distance dispersal of seeds

  (B) lend credibility to the thesis that air currents provide a method of transport for plant seeds to Hawaii

  (C) suggest that the long-distance dispersal of seeds is a process that requires long periods of time

  (D) challenge the claim that ocean currents are responsible for the transport of plant seeds to Hawaii

  (E) refute the claim that Hawaiian flora evolved independently from flora in other parts of the world

  1

  The great variety of plants in Hawaii is a result of the long-distance dispersal of seeds.

  夏威夷植物种类非常丰富,得益于种子的长距离传播。

  2

  There is some dispute about the method of transport involved.

  这些种子是如何到达夏威夷的,科学家们各执一词。

  3

  Some biologists argue that ocean and air currents are responsible for the transport of plant seeds to Hawaii.

  有些生物学家认为,是气流与洋流把这些种子带到夏威夷。

  4

  Yet the results of flotation experiments and the low temperatures of air currents cast doubt on these hypotheses.

  然而,漂浮实验的结果以及气流的低温不禁使人怀疑这些假设。

  5

  More probable is bird transport, either externally, by accidental attachment of the seeds to feathers, or internally, by the swallowing of fruit and subsequent excretion of the seeds.

  更可能的传播方式是通过鸟类,要么是通过偶然附着在羽毛上这种外部方式,亦或是通过鸟类先吃掉果实然后再把种子排出的内部方式。

  6

  While it is likely that fewer varieties of plant seeds have reached Hawaii externally than internally, more varieties are known to be adapted to external than to internal transport. (119 words)

  相对于内部方式,尽管可能只有少数种类的植物种子通过外部方式到达夏威夷,但我们已经知道多数种子,其实更适应外部运输的方式。

  6. The author of the passage is primarily concerned with

  (A) discussing different approaches biologists have taken to testing theories about the distribution of plants in Hawaii

  (B) discussing different theories about the transport of plant seeds to Hawaii

  (C) discussing the extent to which air currents are responsible for the dispersal of plant seeds to Hawaii

  (D) resolving a dispute about the adaptability of plant seeds to bird transport

  (E) resolving a dispute about the ability of birds to carry plant seeds long distances

  选 B

  A 瞎聊项,哪里有 distribution 熟么干系。

  B 正确项

  C 文中的确涉及到了这个内容,但气流跟种子传播无关,作者提到这个点只是为了驳斥句 3 看法,不能说整个文段都在讨论这个问题。

  D 瞎聊项,没有讨论适应性问题,即便涉及到了 adaptability,也看不出什么 dispute。

  E 瞎聊项,没有讨论鸟携带种子的能力,只是说多数种子相对不适应被鸟用肚子带到夏威夷而已,鸟爱不爱吃,能吃多少,我们无从知道

  7. The author mentions the results of flotation experiments on plant seeds most probably in order to

  (A) support the claim that the distribution of plants in Hawaii is the result of the long-distance dispersal of seeds

  (B) lend credibility to the thesis that air currents provide a method of transport for plant seeds to Hawaii

  (C) suggest that the long-distance dispersal of seeds is a process that requires long periods of time

  (D) challenge the claim that ocean currents are responsible for the transport of plant seeds to Hawaii

  (E) refute the claim that Hawaiian flora evolved independently from flora in other parts of the world

  选 D

  参考句 4:

  Yet the results of flotation experiments and the low temperatures of air currentscast doubt on these hypotheses .
