【答案】stretching
【详解】考查非谓语动词。句意：加拿大是一个广阔而美丽的国家，从大西洋一直延伸到

用动名词被动语态的否定形式。故填Not being bathed。

培优第二阶——拓展培优练
阅读理解A
Due to climate changes, Arctic ice is breaking up earlier in the spring, and its area is decreasing.
This is creating problems for polar bears that make their homes off northern Alaska and in Hudson
Bay.
Polar bears off Alaska normally hunt and raise their young on ice sheets that float on the ocean.
But as the ice has melted, the polar bears have been forced to spend more time on land. There, they
have begun to frequent beaches, feeding on the remains of whales caught by native hunters. For
polar bears, this food is less nutritious than seals that they normally catch on ice sheets. The shrinking (
减少) ice has also forced more polar bears into the ocean. In the past, they only had to swim short
distances between ice sheets. But as the ice has shrunk, polar bears have been forced to swim longer
and longer distances in the open ocean. This poses a severe danger during rough weather, and an
increasing number of drowned polar bears have been observed.
In Hudson Bay, the ice breaks up three weeks earlier in the spring now than it did 20 years ago.
Polar bears on Hudson Bay fast (绝食) during the summer, waiting for ice to form in the fall to hunt.
Every year, the summer gets longer, and the bears get skinnier. Over the past 25 years, the average
weight of the female bears has dropped 68 kg. This loss affects their ability to reproduce, and already
the number of births has dropped by 15 percent. Unless the bears can learn to survive these climate
changes, these giants of the ice may one day disappear.
1．What is Arctic ice doing earlier each year?
A．It's freezing. B．It's hardening.
C．It's melting. D．It's expanding.
2．What is true of polar bears that are spending more time on land in Alaska?
A．Their young are dying. B．Their diet is changing.
C．Their health is improving. D．Their families are growing.
3．What does the writer imply about female polar bears in Hudson Bay?
A．They are having fewer young now. B．They suffer from various sicknesses.
C．They don't need stronger protection. D．They can't find enough good males.
4．In which publication would you most likely find this passage?
A．Medical News. B．Society Today.
C．Wildlife Journal D．Design Magazine.
【答案】1．C 2．B 3．A 4．C
【语篇解读】这是一篇说明文。本文讲述了气候变化对于北极熊的生存及繁殖带来的不利
学科网（北京）股份有限公司影响。
1．细节理解题。根据第一段“Due to climate changes, Arctic ice is breaking up earlier in the
spring”可知，由于气候变化，北极的冰在春天的早些时候融化。故选C。
2．细节理解题。根据第二段“Polar bears off Alaska normally hunt and raise their young on ice
sheets that float on the ocean. But as the ice has melted, the polar bears have been forced to spend
more time on land. There, they have begun to frequent beaches, feeding on the remains of whales
caught by native hunters. （远离阿拉斯加的北极熊通常在漂浮在海洋上的冰原上捕食和养育
它们的幼仔。但随着冰的融化，北极熊不得不在陆地上待更长的时间。在那里，它们开始
频繁地出现在海滩上，以当地猎人捕捉到的鲸鱼残骸为食。）”可知，北极熊正常情况下
吃在冰面上可以捕捉到的海豹，但现在由于冰的减少，它们只能以当地猎人捕捉的鲸的残
余物为食了。所以北极熊的饮食发生了改变。故选B。
3．推理判断题。根据最后一段“Over the past 25 years, the average weight of the female bears
has dropped 68 kg. This loss affects their ability to reproduce, and already the number of births has
dropped by 15 percent. （在过去的25年里，母熊的平均体重下降了68公斤。这种损失影响
了它们的繁殖能力，生育数量已经下降了15%。）”可知，因为北极熊的出生率已经下降
了15%，所以作者提到雌性北极熊是想告诉我们，雌性北极熊现在生育的孩子越来越少。
故选A。
4．推理判断题。通读全篇，并结合第一段“ This is creating problems for polar bears that
make their homes off northern Alaska and in Hudson Bay.（这给居住在阿拉斯加北部和哈德逊
湾的北极熊带来了麻烦。）”可以发现文章叙述的是全球气候的变化给北极熊带来的负面
影响,而北极熊属于野生动物,所以推断这篇文章最有可能摘自《野生动物杂志》。故选C。
阅读理解B
Opened in September 2005, Hong Kong Disneyland is the second Disney Park in Asia. It
experienced a difficult time upon its opening. The Park, as well as two themed hotels, was built on
Lantau Island.
The Park opened to strong competition in the form of Ocean Park. Hong Kong Disneyland is
one of only two parks in Hong Kong, which has become one of the world's leading cities in recent
years. It kept Chinese cultural traditions in mind when they built the Park to avoid a cultural
backlash (抵制). Designers added to the custom of Feng Shui.
Disney and Hong Kong announced the Park in 1999, and construction began in 2003. The Park
had one of the shortest construction periods in Disney history. Disney actually announced that the
opening of the Park would be brought forward, from 2006 to September 2005.
The Park attracted 5.2 million visitors in its first year, below the expected 5.6 million. There
was a lack of attractions, with Fantasyland opening with just one dark ride. Summer Passes were
announced to increase the number of tourists. Autopia, Stitch Encounter and it's a Small World
opened between 2006 and 2008 to offer more attractions at the Park.
The number of tourists dropped in 2007 to just over 4 million, so Disney planned a big expansion (
扩大) project to attract more tourists and bring the Park back to its normal level. In July 2009, the
学科网（北京）股份有限公司Legislative Council of Hong Kong passed a three-land expansion of Hong Kong Disneyland, and in
2010, Toy Story Land opened.
These new attractions have certainly paid off, with the Park earning record profit (盈利) in
2013. In that year, over 7 million guests entered the Park.
With enough room for a second Park and the promise of more attractions to come, it seems that
there is indeed a great beautiful tomorrow for Hong Kong Disneyland.
5．What do we know about Hong Kong Disneyland upon its opening?
A．It was the best Disney Park in Asia. B．It wasn't very successful at first.
C．It didn't face much competition. D．It was against Chinese culture.
6．Compared to most other Disney parks, Hong Kong Disneyland ________.
A．is much smaller in size B．has more customs to consider
C．had a longer preparation for opening D．had a shorter period of time for construction
7．What's the author's attitude toward the future of Hong Kong Disneyland?
A．Hopeful. B．Worried.
C．Uninterested. D．Doubtful.
【答案】5．B 6．D 7．A
【语篇解读】本文是一篇说明文，主要介绍了香港迪斯尼的建设及运营情况。
5．推理判断题。根据第四段第一句“The Park attracted 5.2 million visitors in its first year,
below the expected 5.6 million.”可知香港迪斯尼第一年的游客人数不如预期，最初的运营并
不算特别成功。故B项正确。
6．细节理解题。根据第三段第二句“The Park had one of the shortest construction periods in
Disney history.”可知香港迪斯尼的建设时间是迪斯尼历史上最短的，比其他迪斯尼乐园的建
设时间都要短。故D项正确。
7．推理判断题。根据最后一段“With enough room for a second Park and the promise of more
attractions to come, it seems that there is indeed a great beautiful tomorrow for Hong Kong
Disneyland.”可知随着迪斯尼公司采取更多吸引游客的措施，香港迪斯尼似乎有更美好的未
来。由此可见作者对香港迪斯尼的未来充满希望。故A项正确。

【答案及详解】
8．考查非谓语动词。句意：用英语写日记是提高英语写作能力的有效方法之一。当“方
法”讲时，way后常接不定式作后置定语，表示“做……的方法”，故填to improve。
9．考查形容词比较级。句意：与其他形式的写作相比，它更短，所需的时间更少。根据空
前的“shorter”可知此处用形容词比较级形式，故填less。
10．考查名词的数。句意：在用英语写日记的过程中，我们肯定会遇到许多困难。many修
饰可数名词复数，故填difficulties。
11．考查非谓语动词。句意：首先，我们常常很难找到合适的单词来表达我们的想法。
have trouble (in) doing表示“做某事有困难”，故填finding。
12．考查主谓一致。句意：其次，汉语中有很多习惯用语。根据句意可知此处用there be句
型表示“有”，陈述的是客观事实，用一般现在时，根据“many idiomatic ways”可知be用
复数，故填are。
13．考查副词。句意：我们很难把它们准确地译成英语。修饰动词短语 put… into…用副词，
故填properly。
14．考查表语从句。句意：就我而言，我的建议是我们应该随时准备一个笔记本和一本英
汉词典。此处为表语从句，从句成分完整，用 that仅起连接作用，无实义，且不能省略，
故填that。
15．考查固定短语。句意：如果有必要，我们也可以向英语老师求助。ask sb for help表示
“向某人寻求帮助”，故填for。
16．考查固定表达。句意：简而言之，我认为用英语写日记对提高我们的写作能力是很有
用的。此处为“be of+抽象名词”结构，起形容词的作用，be of use=useful，故填of。
17．考查名词。句意同上，作介词 for的宾语用名词，表示抽象意义，不可数，故填
development。

（2019·云南昆明·一模）Finding a mountain goat resting high on a cliff(悬崖) might thrill
many of the millions of tourists who visit Wyoming’s Grand Teton National Park every year, but
park officials say it might be time for the bearded animals to go.
The problem, according to the park, is that Grand Teton’s 100 or so mountain goats threaten
学科网（北京）股份有限公司about 80 bighorn sheep. The bighorn sheep numbered as many as 125 just a few years ago. The
strong goats spread disease and compete with bighorn sheep for food. Unlike small-sized bighorn
sheep, Grand Teton’s mountain goats aren’t native to the park. They were introduced to the park in
the 1960s.
Grand Teton spokeswoman Denise Germann said, “We’ve got a management responsibility to
protect the native species. After hearing from the public on the proposal (建议) in January, park
officials expect to decide as soon as mid-February on what to do about the mountain goats.”
The goats are reproducing rapidly. Now might be the best time to reduce the animals before
they’re too many to bring under control, according to the Park Service.
One wildlife biologist who studies bighorn sheep praised the proposal. Mountain goats’ original
habitat is nowhere close to where they’ve been introduced in the U.S. to provide hunting opportunities,
said Rob Roy Ramey II, with Nederland, Colorado-based Wildlife Science International, Inc.
Wildlife managers should get rid of mountain goats not only in Grand Teton but elsewhere to
help struggling bighorn sheep, Ramey said. “Unfortunately, state wildlife agencies sell nonnative
wildlife viewing opportunities to the public,” Ramey said. “This is not a zoo in the wilderness. It
should really be for native wildlife.”
1．What can be learnt about the bighorn sheep in the park?
A．Their size is huge. B．Their number is decreasing.
C．They arrived in the 1960s. D．They threaten local species.
2．How did the public help park officials protect the bighorn sheep?
A．By providing suggestions. B．By driving away mountain goats.
C．By volunteering in the park. D．By taking over Grand Teton National Park.
3．What is Germann’s attitude towards the bighorn sheep?
A．Curious. B．Proud.
C．Surprised. D．Concerned.
4．What was the purpose of bringing in mountain goats in the beginning?
A．To offer hunting chances.
B．To sell nonnative wildlife.
C．To satisfy wildlife managers.
D．To increase diversities of sheep.
【答案】1．B 2．A 3．D 4．A
【语篇解读】本文属于说明文，介绍美国一所国家公园，雪羊严重影响当地物种大角羊的

1．细节理解题。根据第二段The problem, according to the park, is that Grand Teton’s 100 or so
mountain goats threaten about 80 bighorn sheep. The bighorn sheep numbered as many as 125 just
a few years ago.可知，现在Grand Teton国家公园里的雪羊威胁到了数量为大约80只的大角
羊，而几年以前，大角羊的数量大约为125只，由此可知大角羊的数量在下降，故选B。
学科网（北京）股份有限公司2．细节理解题。根据第三段. After hearing from the public on the proposal (建议) in January,
park officials expect to decide as soon as mid-February on what to do about the mountain goats.”可知
在一月收到公众的建议之后，可能最快2月中旬就会决定怎么应对雪羊这一问题，故可知，
公众通过提出一些建议来帮助公园工作人员保护大角羊，故选A。
3．推理判断题。根据第三段 We’ve got a management responsibility to protect the native
species.可知，对保护本地物种，国家公园有着管理责任，故可知，Germann对大角羊持担
忧的态度，因为受到雪羊的严重影响，故选D。
4．细节理解题。根据倒数第二段 Mountain goats’ original habitat is nowhere close to where
they’ve been introduced in the U.S. to provide hunting opportunities可知，雪羊的原栖息地跟美
国环境很不一样，最初引入美国是为游客提供狩猎的体验，故选A。

they’re a shelter from the stresses of day-to-day life. ___5___ If you’re considering joining your
