下面是出國(guó)留學(xué)網(wǎng)小編為大家整理的2017GRE閱讀題及答案:夏威夷植物種類(lèi)，歡迎大家閱讀。
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.
夏威夷植物種類(lèi)非常豐富，得益于種子的長(zhǎng)距離傳播。
2
There is some dispute about the method of transport involved.
這些種子是如何到達(dá)夏威夷的，科學(xué)家們各執(zhí)一詞。
3
Some biologists argue that ocean and air currents are responsible for the transport of plant seeds to Hawaii.
有些生物學(xué)家認(rèn)為，是氣流與洋流把這些種子帶到夏威夷。
4
Yet the results of flotation experiments and the low temperatures of air currents cast doubt on these hypotheses.
然而，漂浮實(shí)驗(yàn)的結(jié)果以及氣流的低溫不禁使人懷疑這些假設(shè)。
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.
更可能的傳播方式是通過(guò)鳥(niǎo)類(lèi)，要么是通過(guò)偶然附著在羽毛上這種外部方式，亦或是通過(guò)鳥(niǎo)類(lèi)先吃掉果實(shí)然后再把種子排出的內(nèi)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)
相對(duì)于內(nèi)部方式，盡管可能只有少數(shù)種類(lèi)的植物種子通過(guò)外部方式到達(dá)夏威夷，但我們已經(jīng)知道多數(shù)種子，其實(shí)更適應(yīng)外部運(yùn)輸?shù)姆绞健?BR> 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
選 B
A 瞎聊項(xiàng)，哪里有 distribution 熟么干系。
B 正確項(xiàng)
C 文中的確涉及到了這個(gè)內(nèi)容，但氣流跟種子傳播無(wú)關(guān)，作者提到這個(gè)點(diǎn)只是為了駁斥句 3 看法，不能說(shuō)整個(gè)文段都在討論這個(gè)問(wèn)題。
D 瞎聊項(xiàng)，沒(méi)有討論適應(yīng)性問(wèn)題，即便涉及到了 adaptability，也看不出什么 dispute。
E 瞎聊項(xiàng)，沒(méi)有討論鳥(niǎo)攜帶種子的能力，只是說(shuō)多數(shù)種子相對(duì)不適應(yīng)被鳥(niǎo)用肚子帶到夏威夷而已，鳥(niǎo)愛(ài)不愛(ài)吃，能吃多少，我們無(wú)從知道

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