Ⅰ.阅读理解

A

　　“Birds” and “airports” are two words that, paired together,don’t normally paint the most harmonious picture.So it really raises some eyebrows when China announces plans to build an airport that is for birds.

　　Described as the world’s first-ever bird airport, the proposed Lingang Bird Sanctuary(保护区)in the northern coastal city of Tianjin is, of course, not an actual airport.Rather,it’s a wetland preserve specifically designed to accommodate hundreds-even thousands-of daily takeoffs and landings by birds traveling along the East Asian-Australian Flyway.Over 50 species of migratory (迁徙的)water birds,some endangered, will stop and feed at the protected sanctuary before continuing their long journey along the flyway.

　　Located on a former landfill site,the 150-acre airport is also open to human travelers.(Half a million visitors are expected annually.) However,instead of duty-free shopping, the main attraction for non-egg-laying creatures at Tianjin’s newest airport will be a green-roofed education and research center, a series of raised “observation platforms” and a network of scenic walking and cycling paths totaling over 4 miles. 

　　“The proposed Bird Airport will be a globally significant sanctuary for endangered migratory bird species, while providing new green lungs for the city of Tianjin.” Adrian McGregor of an Australian landscape architecture firm explained of the design.Frequently blanketed in smog so thick that it has shut down real airports. Tianjin is a city—China’s fourth most populous—that would certainly benefit from a new pair of healthy green lungs.

【语篇概述】文章主要报道了中国将在天津建立鸟儿机场保护区的计划以及具体规划内容和其重大意义。

1.The underlined phrase “non-egg-laying creatures” in Paragraph 3 refers to 　　　. 

A.endangered water birds

B.planes

C.visitors

D.designers

【解析】选C。词义猜测题。此处non-egg-laying creatures不下蛋的动物就是指来这里的人。从下文中写到的吸引他们的项目就可以看出来,故选C。

2.What do we know about the airport according to the passage?

A.It is located on a landfill site.

B.People cannot watch birds up close here.

C.It provides migratory birds with food and shelter.

D.It functions as an actual airport and a wetland preserve at the same time.

【解析】选C。细节理解题。根据第二段Over 50 species of migratory water birds,some endangered,will stop and feed at the protected sanctuary before continuing their long journey along the flyway,可知这里主要为迁徙中的候鸟提供中途休息和进食的场所,故选C。

3.What can we infer from the last paragraph?

A.Tianjin will win worldwide fame in the future.

B.Tianjin will be able to accommodate more people.

C.The airport will become a permanent home for birds.

D.Tianjin’s air quality will improve thanks to the airport.

【解析】选D。推理判断题。根据最后一段可知天津的现状是空气污染严重,以后将在这方面受益,所以选D。

4.What is this passage mainly about?

A.China is to open the first Bird Airport.

B.Airports turn into green lungs.

C.Birds are no longer enemies to airports.

D.Airports shut down and open up.

【解析】选A。推理判断题。全文主要写的是中国将开办Bird Airport,然后介绍了这个候鸟保护区的主要衍生功能,故选A。

B

　　Trees,some of the tallest in the world,towered above Hannah Griffiths and her colleagues each morning as they walked deep into the rainforest in the Maliau Basin in Bomeo,where they had set up a set of experiments to look at the ecological effects of small creatures:termites(白蚁).

    Termites get a bum rap.They make headlines for chewing up billions of dollars of property each year in the U S.And they are responsible for something like two percent of global carbon emissions,simply as a result of their huge populations and preference for chewing through carbon-rich materials.A whole industry is aiming at killing them. 

    But they play a key role in many natural ecosystems.Scientists have known for years that in tropical(热带的)forests,termites chew up fallen leaves and dead wood,keeping the fallen material under control and letting nutrients from the dead material back into the system to be used by other plants,insects,and animals.But they didn’t know exactly how important the insects were in keeping the forest healthy and functional,so they removed termites from a particular spot in the forest and saw how it responded.

    As luck would have it.Hannah Griffiths and her colleagues started their experiment when the forest was hit by an extreme drought(干旱).During the non-drought years,they saw there wasn’t much difference between the normal plots and the ones where they’d removed the termites.But during the drought,the effects were marked.What they found was unexpected:in the termite-rich areas,the soil stayed slightly wet,more tree seedlings sprouted(抽芽),and the system was full of activity despite the long,hard dry spell.

    For Griffiths,it was only because they happened to study the drought that they could pick out the real importance of termites to the system,she pointed out.“And that rings alarm bells in my head,” she said,“because it makes me think,well,what else don’t we know?If we start damaging biological communities,we don’t know what that will do.”

【语篇概述】这是一篇说明文。短文介绍了白蚁在自然界的生态系统中发挥着关键作用。

5.Which of the following best explains “a bum rap” underlined in Paragraph 2?

A.Unfair blame.

B.Wide popularity.

C.Public attention.

D.Special preference.

【解析】选A。词义猜测题。由第二段第二、三句(它们因为每年在美国吞噬数十亿美元的财产而成为头条新闻。它们对全球大约百分之二的碳排放负有责任,这仅仅是因为它们数量众多,而且喜欢咀嚼富含碳的材料。)所以以上都在说明白蚁受到了不公正的指责。A.Unfair blame不公正的指责;B.Wide popularity广泛受欢迎;C.Public attention公众关注;D.Special preference特别的偏爱。故A选项正确。

6.What have scientists learned about termites?

A.They do serious harm to tropical rainforest.

B.They contribute a lot to the ecosystem they live in.

C.They act as food for other plants,insets and animals.

D.They speed up the loss of nutrition in the rainforest.

【解析】选B。细节理解题。由第三段第二句可知,多年以来,科学家们已经知道,在热带雨林中,白蚁啃食落叶和枯木,控制掉落的物质,并让枯木中的营养物质重新回到生态系统中,供其他植物、昆虫和动物使用。所以关于白蚁,科学家们了解到它们为它们所生活的生态系统做出了很大的贡献。故B选项正确。

7.What can we infer from the finding of Griffiths’ experiment?

A.Termites benefit more from the forest during the drought.

B.Termites prefer drought years to non-drought ones.

C.Termites help rainforest survive climate change.

D.Termites enjoy eating tree seedlings during the drought.

【解析】选C。推理判断题。由第四段最后两句“但在干旱期间,这些影响是很显著的。他们的发现出乎意料:在白蚁多的地区,土壤仍保持轻微的湿润,更多的树苗发芽,尽管经历了漫长而艰苦的干旱期,周围的生态系统仍然充满活力。”可推知,白蚁帮助雨林在气候变化时得以生存。故C选项正确。

8.What does Griffiths tell us in the last paragraph?

A.Termites are now in danger of extinction.

B.We should think twice before damaging a species.

C.Termites damage biological communities.

D.We should study the drought to improve the system.

【解析】选B。段落大意题。由最后一段内容(她指出,对格里菲斯来说,只是因为他们碰巧研究了干旱,他们才能够发现白蚁对生态系统的真正重要性。“这在我脑海中敲响了警钟,”她说,“因为它让我想,我们还不知道什么?如果我们开始破坏生物群落,我们不知道会发生什么。)所以判断出格里菲斯在最后一段告诉我们,在破坏一个物种之前,我们应该三思而后行。故B选项正确。

【技法总结】推理判断题测试考生在阅读基础上的逻辑推理能力,要求考生根据文章所述事件的逻辑关系,对题目考查的内容做出合理的推断;或根据作者所阐述的观点理论,对文章未涉及的现象、事例予以解释。有时候也会考查作者的态度,题材出处等方面的推断。对于这种题目,考生首先要仔细阅读短文,全面了解信息,再结合相应的段落和句子,推测相关题目的答案。比如上面的第五题和第七题,都需要对文章内容,尤其是一些关键语句进行全面的理解和推测。

Ⅰ.阅读理解

　　In the trailer (拖车式房屋),Sischo was refreshing the snails’ accommodations—an ongoing routine that takes days of careful work.He had found a dozen of Achatinella bulimoides—a third of the world’s population of the species.Once every individual was accounted for, he cleaned the cage and packed in new leaves.The work took much trouble, but the responsibility, he said, was like “a heavy weight sitting on you.”

　　The trailer is very vulnerable.It’s designed to keep away would-be theft, and to resist hurricanes.But a fire could easily destroy it, or a disease could sweep through it.Last September , a mystery pathogen(病原体)appeared to have entered the trailer on leaves fed to the snails, killing almost the entire species.As sad as the event was, there’s no good way to insure against future catastrophe.The snails can’t simply be spread among zoos or other facilities: they need special equipment, experienced handlers, and a diet of native Hawaiian plants.

　　Consequently, it can be hard for the snails’ minders to relax, even when they are outside the trailer.“How do you switch off when your decisions mean existence or extinction?” Sischo said.While action lightens the burden, yet with animals whose natural history is largely unknown, that action can be dangerous.“If you do it wrong, the snails die.”

　　Snails are neither intelligent nor beloved.Sischo’s friends sometimes tease him about being “the strange snail guy” ; strangers ask why he cares.It’s hard to convince people, but he insists that if he can just get them in the trailer, they will understand why the Achatinella bulimoides are worth saving.“People melt,” he said “When you show them that the entire population is in this chamber, it hits them.”

【语篇概述】本文为说明文,主要介绍了为了拯救濒临灭绝的蜗牛物种,人类为它们制作了特殊的设备——拖车式房屋,经验丰富的驯养员和夏威夷本地植物的饮食,这些都有益于蜗牛的保护。

1.What is the trailer used for?

A.Accommodating guests.

B.Sheltering snails.

C.Planting vegetables.

D.Alarming thieves.

【解析】选B。推理判断题。根据第二段的内容可知,蜗牛不能简单地在动物园或其他设施中生存,它们需要特殊的设备。这个特殊的设备就是the trailer。由此可知, the trailer 是给蜗牛住的房子,是收容蜗牛,为其遮风挡雨的。故B项符合题意。

2.What does the underlined word “vulnerable” mean in Paragraph 2?

A.Quiet.

B.Safe.

C.Easily affected.

D.Well protected.

【解析】选C。词义猜测题。根据画线词后的内容可知,拖车式房屋的设计是为了防止潜在的盗窃,并抵御飓风。但是一场火灾可以轻易地摧毁它,或者一种疾病可以席卷它。由此可推断出,这种拖车式房屋是易受其他因素影响的。故选C。

3.What is the snail minders’ attitude towards their job?

A.Relaxed.　　　　　 B.Confident.

C.Cautious.    D.Disapproving.

【解析】选C。推理判断题。根据第三段“If you do it wrong, the snails die.”可知,蜗牛看护者对待他们工作的态度是谨慎小心的。故选C。

4.Which of the following could be the best title for the text?

A.The Last of Its Kind

B.The Worst of Times

C.Mourn Its Loss

D.Resist Possible Dangerous

【解析】选A。主旨大意题。根据文章内容可知,这种蜗牛的数量极少,故A项“这种物种最后的几条蜗牛”为短文最佳标题。

【语篇概述】这是一篇夹叙夹议类的文章。在现代,野生动物正在遭受巨大威胁,每天都有一些物种灭绝。白鹤就是其中之一。但是,有很多人正在竭尽全力保护这些物种免于灭绝。Chris和Tim通过努力,帮助一只名叫Emma的雌鹤繁殖了五只幼鹤。

1.A.growing　　　　 B.migrating

C.competing    D.disappearing

【解析】选D。根据第一段第一句“Wildlife has been greatly threatened in the modern age”和第一段最后一句中提到的“...the species from going out of existence”可以推知,野生动物正在遭受巨大威胁,每天都有一些物种灭绝,即:“消失”。D选项正确。

2.A.ban   B.save

C.split    D.remove

【解析】选B。前文提到每天都有物种消失,那么该句应指科学家们正在竭尽全力保护这些物种,使它们免于灭绝。故B选项正确。

3.A.care　　　　B.eye　　　　C.mind　　　　D.story

【解析】选A。自从2004年,Emma一直由Chris和Tim照顾。该空和下一句中的“human caretakers”呼应。故选A。

4.A.found   B.chosen

C.raised   D.seized

【解析】选C。根据空后的“human caretakers”可知,caretaker当然是照看Emma的。故该句应指:出生在一个国际鹤基地,Emma由人类抚养照看。故选C。
