展开A
Scientists researching climate change in Antarctica are studying penguins in an effrt t better understand the area’s envirnmental health. They’re measuring the grwth and develpment f the penguin ppulatin n the eastern side f the Antarctic Peninsula. "We are cunting penguin nests t understand hw many penguins are in a clny(聚居地), prducing yung animals every year, and whether that number is ging up r dwn with the envirnmental cnditins," said Alex Brwicz, an eclgy researcher at New Yrk’s Stny Brk University.
The wrk is nt easy fr climate researchers in the icy, faraway reaches f Antarctica. But penguins are easier t fllw than sme ther kinds f animals — they nest n land. And their black bdies and waste drppings can als be identified against the area’s white backgrund.
Michael Wethingtn, anther researcher frm Stny Brk, tld Reuters the penguin ppulatin can represent verall climate cnditins and the health f the area’s whle ecsystem.
The researchers say cunts f individual penguins can be cmbined with data frm satellite images t get a mre cmplete picture f hw the animals are prgressing.
Gent penguins prefer pen water withut brken pieces f ice flating arund. S when temperatures n the Antarctic Peninsula began rising during the latter half f the 20th century, gent ppulatins mved suth. "Gent penguins dn’t like sea ice," David Ainley, a bilgist wh has been studying penguins fr mre than 50 years, tld Reuters. "They mstly search fr fd ver the cntinental shelf(大陆架) and dn’t g far ut t sea."
As sea ice has decreased alng the western side f the peninsula, gents seem t have gt used t the changed cnditins. But thse same cnditins have been wrse fr the Adélie penguin species. This is because they depend n sea ice fr feeding and reprductin(繁殖). "When we find Adélie penguins, we typically knw sea ice is nearby," Wethingtn said. He added that whenever researchers see sea ice decreasing r disappearing, they als see Adélie penguin ppulatins drp sharply.
气候变化一直以来都是人们普遍关注的问题。科学家从未放松对气候变化的研究。一些科学家通过对南极洲企鹅进行观察来研究南极洲的气候变化。
1. Why did the researchers chse penguins as their research subject?
A. Because their clny is in gd cnditin.
B. Because Antarctica has a large ppulatin f penguins.
C. Because they are easier t fllw and identified than ther animals.
D. Because their number changes sharply with the envirnmental cnditins.
解析 C 细节理解题。由第二段中的"But penguins are easier t fllw than sme ther kinds f animals — they nest n land. And their black bdies and waste drppings can als be identified against the area’s white backgrund"可知,研究人员之所以选择企鹅是因为它们更易于跟踪和辨认,故本题选C项。
2. What des the underlined wrd "picture" in Para. 4 prbably mean?
A. Pht.B. Future.
C. Predictin.D. Situatin.
解析 D 词义猜测题。结合关键性信息cunts f individual penguins,data frm satellite images,the animals are prgressing以及常识我们不难推知,研究人员通过不同手段收集有关企鹅的各种信息,无非是想对企鹅这一动物族群的"发展状况"有一个更为全面的了解,那么picture在意义上与situatin最为接近,故本题选D项。
3.What can we infer abut Adélie penguins frm the last paragraph?
A. They feed n ice and bring up their babies n ice t.
B. They cmpete fr fd and space with gent penguins.
C. They are respnsible fr the decrease r disappearance f ice.
D. They wn’t live in the west f the Antarctic Peninsula in great numbers.
解析 D 推理判断题。由"This is because they depend n sea ice fr feeding and reprductin(繁殖)"可知,Adélie penguins对海冰依赖性很强。再由"As sea ice has decreased alng the western side f the peninsula, gents seem t have gt used t the changed cnditins. But thse same cnditins have been wrse fr the Adélie penguin species"可知,南极半岛西侧海冰数量减少,那里的环境条件自然不会适合Adélie penguins大量生存繁衍。综上可知,本题选D项。
4. Which is the best title fr this text?
A. Climate Change Has Put Penguins in Danger
B. Scientists Use Penguins t Study Antarctic Climate Change
C. The Present Living Cnditins fr Penguins in Antarctica
D. Sea Ice Has Different Influences n Gent Penguins and Adélie Penguins
解析 B 标题归纳题。通读全文我们不难发现,文章首句是整篇文章的主题句,指明了文章的主要内容:科学家借助企鹅来研究南极洲的气候变化,故B项做文章的标题最佳。

科学家们开发了一种新的人工智能技术,可以通过分析人脸上的肌肉来判断某人是否在说谎。
1.havedevelped 考查时态、语态和主谓一致。由时间状语Over the past few years可知,此处用现在完成时;主语scientists与develp之间为主谓关系,故填have develped。
2.tcalculate 考查非谓语动词。固定短语be able t d sth.表示"能够做某事",故填t calculate。
3.Invented 考查非谓语动词。分析句子成分可知,空处应填非谓语动词。动词invent与the machine之间是逻辑上的动宾关系,非谓语动作已完成,故用过去分词形式Invented。
4.away 考查固定搭配。give away表示"泄露,暴露"。
5.usually 考查副词。所填词修饰动词,故应用副词作状语,所以填usually。
6.their 考查形容词性物主代词。所填词修饰名词eyes,应用形容词性物主代词their。
7.Clsing 考查非谓语动词。分析句子结构可知,主句有系动词is,故is前的部分为主语。此处表示主动关系和一般性行为,故填Clsing。
8.truth 考查名词。空处应填名词truth(事实,真相)。
9.A 考查冠词。分析句子成分可知,空处应用冠词。此处表示泛指,且real的发音以辅音音素开头,故填A。
10.when/if 考查状语从句。分析句子结构可知,空处应填连词。再结合句意可知,空处可以用when引导时间状语从句;空处也可以用if引导条件状语从句。
