Ⅰ.阅读理解

A

A new study focused on birds examines how the movements of rivers in the Amazon have contributed to that area's exceptional biological diversity.The research team, led by the American Museum of Natural History, found that as small river systems change over time, they  spur  the evolution of new species. The findings also reveal previously unknown bird species in the Amazon that are only found in small areas next to these dynamic river systems, putting them at high risk of extinction.

The lowland rainforests of the Amazon River basin harbor(藏匿) more diversity than any other ecosystem on the planet. It is also a globally important biome(生物群落) containing about 18 percent of all trees on Earth and carrying more fresh water than the next seven largest river basins combined. Researchers have long wondered and hotly debated how the Amazon's rich biodiversity arose and accumulated.

“Early evolutionary biologists like Alfred Russel Wallace noticed that many species of primates and birds differ across opposite riverbanks in the Amazon，”said the study's lead author Lukas Musher. “Moreover, accumulating geological evidence has suggested that these rivers are highly dynamic, moving around the South American landscape over relatively short time periods, on the order of thousands or tens of thousands of years.”

To investigate how the movement of rivers across the landscape has influenced the accumulation of bird species in the Amazon, the researchers sequenced the genomes(基因组) of six species of Amazonian birds.

Because these rivers move around the landscape at different time scales, their movements can have varying outcomes for bird species: when river rearrangements occur quickly, populations of birds on each side can combine before they've had time to differ; when river changes happen slowly, species have a longer time to diverge from one another.

1．What does the underlined word “spur” in Paragraph 1 mean?

A．Stimulate.　 B．Renew.

C．Pursue.  D．Interrupt.

2．What have researchers debated on?

A．What the Amazon's biodiversity indicates.

B．How the Amazon's biodiversity was formed.

C．Whether the Amazon has the richest biodiversity.

D．Why Amazon bird species are at risk of distinction.

3．What can we conclude from Lukas Musher's words?

A．There are six species of American birds.

B．Rivers move very slowly in South America.

C．Most species differ across opposite Amazon riverbanks.

D．River movement may lead to the Amazon's biodiversity.

4．What has influenced the change of bird species in the Amazon?

A．The location of river movement.

B．The populations of birds.

C．The speed of river movement.

D．The amount of the genomes.

[语篇解读]　本文是一篇说明文。本文介绍了亚马逊河的流动对该地区生物多样性的贡献。

1．A　[词义猜测题。根据划线处上文“A new study focused on birds examines how the movements of rivers in the Amazon have contributed to that area's exceptional biological diversity.”和划线单词所在句子“The research team, led by the American Museum of Natural History, found that as small river systems change over time, they spur the evolution of new species”可知，亚马逊河的流动促进该地区非凡的生物多样性，这说明小型河流系统会发生变化，从而刺激新物种的进化，由此可知，spur可以解释成导致、引起，再往深一点是刺激了物种的进化。A.stimulate刺激；B.renew翻新、更新；A.pursue追求；D.interrupt打断。故选A。]

2．B　[细节理解题。根据第二段最后一句“Researchers have long wondered and hotly debated how the Amazon's rich biodiversity arose and accumulated.”可知，调查者们正在争论的是亚马逊河河流丰富的生物多样性是如何形成并累积的，故选B。]

3．D　[推理判断题。根据第三段“Early evolutionary biologists like Alfred Russel Wallace noticed that...on the order of thousands or tens of thousands of years.(“此外，越来越多的地质证据表明，这些河流是高度动态的，在相对较短的时间内，在数千年或数万年的时间内，在南美洲的景观中流动。”)” Lukas Musher将这两件事关联起来，他认为是亚马逊河的流动导致了河两岸丰富的生物多样性，故选D。]

4．C　[细节理解题。根据最后一段中“when river rearrangements occur quickly,
