GRE阅读机经 Passage 83

Throughout much of the Tertiary period (most of the past 65 million years), the Arctic supported continuous forests. Only toward the end of that period does the fossil evidence show that certain present-day Arctic plants were established and widely distributed throughout the Arctic. Many Arctic plants are thought to have originated in the high mountain ranges of central Asia and North America, to have spread northward to the Arctic as global temperatures fell in the late Tertiary, and to have achieved a circumpolar distribution by the end of the Tertiary (about 2 million years ago). However, fossil evidence to support these proposals is either lacking or fragmentary. Consequently, the routes by which these plants expanded their ranges during their colonization of the Arctic remain unknown.

文章解析

第一句：

Throughout much of the Tertiary period (most of the past 65 million years), the Arctic supported continuous forests.

白话版讲解： 在第三纪时期的大部分时间里，北极地区都有连绵不断的森林。

第二句：

Only toward the end of that period does the fossil evidence show that certain present-day Arctic plants were established and widely distributed throughout the Arctic.

白话版讲解： 化石记录表明，只有在第三纪末的时候，北极地区才出现了一些现代的植物物种。

第三句：

Many Arctic plants are thought to have originated in the high mountain ranges of central Asia and North America, to have spread northward to the Arctic as global temperatures fell in the late Tertiary, and to have achieved a circumpolar distribution by the end of the Tertiary (about 2 million years ago).

白话版讲解： 人们认为很多北极地区的植物都是发源自中亚和北美的高山地区，随着第三纪末期全球气温降低，而后一路往北延伸到北极地区，并且分布在了极地周围。

第四句：

However, fossil evidence to support these proposals is either lacking or fragmentary.

白话版讲解： 但是，化石证据并不能支持这种观点，这些证据要么没有，要么不完整。

第五句：

Consequently, the routes by which these plants expanded their ranges during their colonization of the Arctic remain unknown.

白话版讲解： 因此，这些植物的迁徙路线到底是怎么样的，目前依然是个未解之谜。

GRE阅读题目解析

Consider each of the choices separately and select all that apply.

1.Which of the following statements about Arctic plants is supported by the passage?

A. The decline in global temperature in the late Tertiary prevented many high-mountain plants from becoming established in the Arctic. B. There is not enough evidence to firmly establish the historical migration routes of present- day Arctic plants. C. Present-day Arctic plants are less likely to leave fossil remains than are plants outside the Arctic. 答案： 这道题问的是，以下哪个（些）有关北极地区的说法能够得到原文的支持？这道题应该选 B，根据原文第 4、5 句话的内容，作者认为和北极植物迁徙路线的相关证据并不完整，因此这个迁徙路线依然是未解之谜。 A. 第三纪晚期全球气温下降，导致很多的高山植物没有在北极地区生长繁殖下来。（原文没提到） B. 没有足够证据能够确诊北极地区植物的历史迁徙路线。 C. 和北极圈以外的植物相比，现在北极圈的植物更不容易留下化石证据。（原文没提到）

2.The context in which it appears, “distributed” most nearly means

A. developed. B. isolated. C. dispersed. D. divided. E. disconnected. 答案 ▼ 这道题问的是，原文中的 “distributed” 这个单词，最接近于以下哪个单词的意思？这道题应该选 C，distributed 在原文就表示分布、分散在……的意思。 A. 发展 B.（使）隔离，孤立，脱离 C.（使）分散，散开；疏散；驱散 D. 分割，分成… E. 切断
