When Ariel Cordova reached Jamaica Bay Wildlife Refuge in Queens，New York，last November，she planned to go hiking and bird watching．A mile into her walk，she noticed a beautiful female mute swan (疣鼻天鹅) near the water's edge．Cordova，who had worked at the Wild Bird Fund recovery center in Manhattan，knew that swans can attack people．But strangely，as she got close to this one，it didn't move．So she was certain that the bird was ill and needed medical attention．Cordova put her jacket over the bird's head to keep it calm，carefully picked it up，and held it in her arms．And then a thought came to her：What do I do now
Her best choice was the Wild Bird Fund recovery center，but that was on the other side of the town．How was she going to transport a 17 pound swan on foot all that way？Luckily，a stranger offered her a bike and then she took the swan to a nearby subway station by bike．
On the subway，no one seemed to be astounded by the feathered passenger．“Even one guy，who was sitting right in front of me，just gave the swan a calm glance，” says Cordova．
Cordova called the recovery center，and Tristan，an animal care manager，picked her up at the subway station and drove the bird to the recovery center．There，staff members decided that the swan might have been hurt by a fish hook．
The staff looked after the swan carefully and got it back up on its webbed feet．The swan even made a boyfriend in the center．Sadly，it had a bacterial infection．Two months after Cordova came to its rescue，it passed away．
It's a disappointing ending，but the real story is just how far some people are willing to go to save a swan in the big city literally (确实地)．In all，Cordova traveled two hours by bike，by subway，and by car to save it with endless efforts．Tristan says，“We are angels of love．That's the perfect summary of who we are．I firmly believe that we will continue to save wildlife．”
4．Why did Cordova decide that the swan was ill

B．It moved up and down．
C．It attacked her．
D．It stood near the water's edge．

C．It died though it had been cared well．
D．It was sent to the recovery center by two strangers．
7．Which of the following can best describe Cordova

B．Modest and thankful．
C．Brave and generous．
D．Curious and creative．
Ⅳ．阅读七选五
The world is losing monarch butterflies at a striking rate，as kinds of human activities destroy natural habitats． 1 Climate change，with its extreme storms，prolonged droughts and warming temperatures，is to destroy the forest that serves as the butterfly's winter home．
Scientists believe，to help these lovely butterflies，it is necessary to create an ecosystem where the butterflies will be able to survive．They've decided to start a monumental project． 2
“It's an idea that may sound crazy，” said Cuauhtemoc Saenz Romero，a forest geneticist．“But by the end of the century，it may be absolutely needed．”
The butterflies that winter here seek shelter in the oyamel firs． 3 The firs protect the butterflies from chilly winter rains and create a microclimate cold enough to keep the butterflies in a state of hibernation but not so cold as to kill them．
4 The region is warming at such an accelerated pace that the trees won't be able to adapt，scientists say，and will need to help migrating to areas where the climate is predicted to be suitable for them in future years．
Over the last several years，the team of researchers has overseen the relocation of about 1，000 young fir plants，which were growing at lower altitudes，up to higher—and cooler—elevations． 5 They are now establishing the trees at even higher altitudes on other nearby mountains—seeding ecosystems now that monarchs could potentially use later if temperatures continue to rise．
Every winter is witnessing tens of thousands of butterflies in the new forests，some fluttering about and others resting in massive clumps on the firs，their bodies obscuring the branches and trunks．
A．They hope to expand the project．
B．There is still hope to restore the forests．
C．Their dense tops act as an umbrella for the butterflies．
D．But the biggest threat yet has only recently come into focus．
E．They are trying to move an entire forest 1，000 feet up a mountain．
F．Scientists fear that climate change may kill off these firs altogether．
G．The project is believed to protect the butterfly and the natives as well．

Ⅲ．【语篇解读】　本文是一篇应用文。文章主要介绍了爱丁堡国际艺术节期间游客们可以去的餐厅。
1．B　[细节理解题。根据文章Eleanore部分中的“Named after Roberta's boat，Eleanore is comfortable with highlevel seating and decorated in white and blue．”可知，Eleanore以罗伯塔的船命名。故选B。]
2．C　[细节理解题。根据文章Bertie's部分中的“Its private area is the perfect place to celebrate parties and special group events for quiet dinners．The large space can serve groups of up to 300 guests．”可知，Bertie's私人区域是庆祝聚会和特殊团体活动的理想场所，而且空间大到可以为多达300位客人提供服务。由此可知，Bertie's最适合公司举办晚宴。]
3．D　[细节理解题。根据文章Williams & Johnson部分中的“‘Willie Jay's’，as it is known to locals，specializes in singleorigin coffees to celebrate their individual characters．They pride themselves on their seasonally picked coffees and their selection changes through the year as they continue to source new fresh crop beans．Each coffee is carefully designed to make the bean's best smell and served in the airy cafe．”可知，Williams & Johnson一直对咖啡豆精心挑选。]
【语篇解读】　本文是一篇新闻报道。文章主要讲述了Ariel Cordova拯救疣鼻天鹅的故事。
4．A　[推理判断题。根据第一段的“Cordova，who had worked at the Wild Bird Fund recovery center in Manhattan，knew that swans can attack people．But strangely，as she got close to this one，it didn't move．”可知，Cordova之所以断定这只天鹅病了，是因为它行为异常。]
5．D　[词义猜测题。根据下文“‘Even one guy，who was sitting right in front of me，just gave the swan a calm glance，’ says Cordova．”可知，在地铁上，似乎没有人对这位长着羽毛的乘客感到吃惊。所以画线词的意思是“惊讶的”，即shocked。]
6．C　[细节理解题。根据第五段的“Sadly，it had a bacterial infection．Two months after Cordova came to its rescue，it passed away．”可知，尽管得到了康复中心很好的照顾，这只天鹅还是死于细菌感染。]
7．A　[推理判断题。根据最后一段的“In all，Cordova traveled two hours by bike，by subway，and by car to save it with endless efforts．”可知，Cordova就像爱的天使，为了拯救这只天鹅，她克服了各种困难，从城镇的另一边，坚持不懈地把它送到康复中心。由此可知，Cordova是善良的和体贴的。]
Ⅳ．【语篇解读】　本文是一篇说明文。文章主要介绍了人类为了保护因气候变化正在消失的帝王蝶所做出的一些努力。
1．D　[上文提到了人类活动导致帝王蝶正在消失，后文则重点指出了气候变化对其的影响，可见空处与上文构成转折，旨在说明帝王蝶面对的最大威胁是气候变化。D选项“但是最大的威胁直到最近才成为焦点”符合语境，下文是对这个威胁的具体说明。故选D。]
2．E　[上文提到科学家决定开始一项浩大的工程，空处为本段最后一句，应承接上文说明这一工程是什么。E选项“他们试图将整片森林移到1 000英尺高的山上”符合语境，选项中They指代上文中的Scientists。故选E。]
3．C　[上文提到蝴蝶在冷杉中寻求庇护，后文则提到了冷杉是如何保护蝴蝶的，C选项“它们浓密的顶部就像蝴蝶的伞”符合语境，选项中umbrella呼应上文中的shelter。故选C。]
4．F　[后文提到科学家指出树木无法适应气候变化，需要帮助它们迁移，可见气候变化可能对冷杉造成消极影响，故F选项“科学家们担心气候变化可能会使这些冷杉全部灭绝”符合语境，故选F。]
5．A　[上文提到冷杉幼苗在低海拔地区生长，后文则提到研究小组在海拔更高的山上种植这些树，即他们在增加这些树木的数量，A选项“他们希望扩大这个项目”符合语境，故选A。]
