Ⅲ.阅读理解
A
Although our reliance ( http: / / www.21cnjy.com )on fossil fuels(化石燃料) has created global warming, we now have the opportunity to begin a_transformation towards a clean energy economy—one that is supported by highly efficient industries, fueled by clean, renewable resources, like wind, solar and geothermal (地热的) energy, and based on modern smart transportation planning.21教育网
A clean energy econom ( http: / / www.21cnjy.com )y is a win for American jobs. Studies by leading research institutions have shown that if we invest in clean energy over fossil fuels, we will create more American jobs. A report released by the United Steelworkers and the Sierra Club, for example, found that thanks to the growth of wind energy, about 5，200 manufacturing jobs could be created in Iowa alone over the next decade. Additional studies have found that thousands more jobs could be created in other states that have suffered industry job losses and that welcome the opportunity to train workers for the new energy economy.21·cn·jy·com
But, in order to ( http: / / www.21cnjy.com ) fully transit to a clean energy economy，we need our elected officials to take action. Without policies from the government, the private field may continue to invest in old－fashioned, polluting technologies. More than 70 coal plants without technology to capture carbon pollution are now being considered. If these projects go ahead, this will be billions of dollars invested in technology that is outdated and not “clean coal”. We need effective policies to push growing clean energy industries forward.
Each of us can p ( http: / / www.21cnjy.com )lay a role in bringing about this much－needed transition. Tell your business and elected leaders that the next generation deserves to grow up in a world powered by clean energy. Tell your mayor that you want city planning that encourages more efficient new buildings and sidewalks and bike paths that make it easy to walk or ride a bike. Tell your state and national officials to invest in energy grids (电力网) that can deliver renewable energy to everyone. Tell your company that instead of old－style coal power you want to buy solar, wind, or geothermal energy. Tell your elected officials that you want national policies that encourage investors to make long－term commitments to clean energy.
1．The underlined ( http: / / www.21cnjy.com )part “a transformation” in Paragraph 1 refers to “________”．
A．a change from fossil fuels to clean energy
B．a choice for fossil fuels
C．a chance of developing modern industries
D．a choice for global warming
2．Which of the follo ( http: / / www.21cnjy.com )wing is a major concern to the government according to the passage 21教育名师原创作品
A．Investments in clean energy.
B．Coal plants without advanced technology.
C．Technology for capturing carbon pollution.
D．Policies on the good use of clean energy.
3．What is Paragraph 4 mainly about
A．Everyone can contribute to the clean energy.
B．Citizens have the right to talk to the mayor.
C．Elected leaders should be responsible for the next generation.
D．More investments should be put into energy grids.21*cnjy*com
4．If this pass ( http: / / www.21cnjy.com )age is taken from a newspaper, in which part would you most probably find it
A．Culture. B．Society.
C．Economy. D．Nature.
B
Beijing had its bigg ( http: / / www.21cnjy.com )est snowfall since 1951.Britain is suffering through its longest cold snap(寒潮)since 1981.And freezing weather is hitting the Deep South，including Florida's orange groves and beaches.
Whatever happened to global warming
Such weather doesn't ( http: / / www.21cnjy.com ) seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases.But experts say the cold snap doesn't contradict global warming at all—it's just a temporary phenomenon in the long－term heating trend.“It's part of natural variability，”said Gerald Meehl，a senior scientist.With global warming，he said，“we'll still have record cold temperatures.We'll just have fewer of them.”
Scientists say man ( http: / / www.21cnjy.com )－made climate change does have the potential to cause more frequent and more severe weather extremes.But experts did not connect the current cold snap to climate change.
So what is going on
“We basically have se ( http: / / www.21cnjy.com )en just a big outbreak of Arctic air over populated areas of the Northern Hemisphere”，Arndt said.
In the atmosphere，lar ( http: / / www.21cnjy.com )ge rivers of air travel roughly west to east around the globe between the Arctic and the tropics.This air flow acts like a fence to keep Arctic air restricted.But recently，this air flow has become bent into a zigzag(之字形)pattern，wandering north and south.If you live in a place where it brings air up from the south，you get warm weather.In fact，record highs were reported this week in Washington state and Alaska.
But in the eastern U ( http: / / www.21cnjy.com )nited States，like some other unlucky parts of the globe，Arctic air is coming from the north.And that's how you get a temperature of 3 degrees in Beijing，a reading of minus－42 in mainland Norway，and 18 inches of snow in parts of Britain.The zigzag pattern arises naturally from time to time，but it is not clear why it's so strong right now.
5．What is the BEST title of the text
A．Freezing weather is hitting the Deep South
B．We'll still have record cold temperatures
C．The air flow has become a zigzag pattern
D．Cold snap doesn't contradict global warming
6．With global warming，we will________．
A．also meet with severe cold snap
B．have more hot temperatures forever
C．never experience cold temperatures
D．have more cold temperatures
7．According to experts，the current cold snap
________．
A．suggests that the climate has changed greatly
B．is not related to the climate change
C．shows that the climate will turn cold
D．is affected by global warming
8．Beijing had its biggest snowfall since 1951 because of ________．
A．a fence from the Arctic
B．a cooling trend in climate
C．a big outbreak of Arctic air
D．its large population

Ⅲ.阅读理解(共20小题；每小题2分，满分40分)
A
As computers become m ( http: / / www.21cnjy.com )ore popular in China, Chinese people are increasingly relying on computer keyboards to input Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes(笔画) of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.21教育网
Do you write b ( http: / / www.21cnjy.com )y hand more or type more In Beijing, students start using a computer as early as primary school. And computer dependence is more widespread among university students. Almost all their assignments and essays are typed on a computer.
All the students interviewed say they usually use a computer.
It's faster and eas ( http: / / www.21cnjy.com )ier to correct if using a computer. And that's why computers are being applied more and more often to modern education. But when people are taking_stock_in computers increasingly, problems appear.
“When I'm writing w ( http: / / www.21cnjy.com )ith a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it.”【出处：21教育名师】
“I'm not in the mood to write when faced with a pen and paper.”
Many students don't ( http: / / www.21cnjy.com )feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite
Many educators think d ( http: / / www.21cnjy.com )ifferently. Shi Liwei, the headmaster of a famous primary school in the capital, said, “Chinese characters enjoy both practical and aesthetic(审美的) value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them.”
To encourage stude ( http: / / www.21cnjy.com )nts to handwrite more, many primary schools in Beijing have made writing classes compulsory(必修的) and in universities, some professors are asking students to turn in their homework and essays written by hand.
36．Which of the following can best serve as the title of the passage
A．The Importance of Handwriting and Typing
B．To Type or to Handwrite
C．Writing by Computer Will Replace Writing by
Hand
D．Practical and Aesthetic Value of Chinese Characters2-1-c-n-j-y
37．The students int ( http: / / www.21cnjy.com )erviewed prefer to write using a computer mainly because________．【来源：21cnj*y.co*m】
A．they are usually asked to e－mail their homework and essays
B．they can correct the mistakes they make quickly and conveniently
C．they find it not easy to remember how to write a character
D．computers have become a trend and fashion in Chinawww.21-cn-jy.com
38．The underlined ex ( http: / / www.21cnjy.com )pression “taking stock in” (Paragraph 4) probably means________．
A．getting bored with B．getting dependent on
C．becoming crazy about D．getting curious about
39．We can draw the conclusion from the passage that________．
A．more and more students will give up writing on a computer
B．writing by hand will give way to typing by computer one day
C．more and more students will pay attention to handwriting
D．the typing article better expresses one's emotion and quality
B
I have to say I ( http: / / www.21cnjy.com )usually want to throw up when I hear someone say each of us has a purpose because I realize that as far as most people are concerned it is the cliche (陈词滥调). I do believe it is true that as humans we all feel that we must be here for a purpose, but I also know that most of us have no idea what that purpose is.
For most people th ( http: / / www.21cnjy.com )e problem is that they don't believe that they have a passion. I know you hear it all the time：“find your passion”. The key step is hard to make if someone is so numb，that they don't know what their passion could possibly be. Somehow we seem to hang onto our failures and limits more than we do our success，which is just human nature. Stop and think about the things that you have always done well and loved to do，which will help you find your passion.
We should know it's ( http: / / www.21cnjy.com ) easy to determine our purpose, but your purpose must be combined with your passion. For example, I have been involved in weight lifting and fitness since I was in my twenties and have a great deal of self－taught knowledge about bodybuilding. All I had to do was take an exam from a certifying organization to gain my certification and be a fitness trainer which is my purpose. I had a purpose and passion so I made it at last.
Generally, you ( http: / / www.21cnjy.com )r purpose must be in the area that you love, enjoy and are passionate(狂热的，热诚的) about and that is why you have chosen to spend time and energy to realize it. Your success will always be greater when you are working in an area that you are passionate about.
40．The author believes that________．
A．each of us has a purpose
B．few people have a purpose
C．most of us have a purpose
D．all of us need a purpose
41．Many people can't get rid of their failures because________．
A．they have become very numb
B．they don't know what success is
C．it's difficult to change their nature
D．many things limit their actions
42．The author ( http: / / www.21cnjy.com ) uses his own example in Paragraph 3 to show that________．
A．being a fitness trainer is promising
B．purpose and passion can lead to success
C．it's possible for you to find a purpose
D．all successful people have a purpose
43．You should choose your purpose in the area where21·cn·jy·com
________．
A．you have expert knowledge，interest and passion
B．you have to work hard to make a living
C．you have interest and less special knowledge
D．you enjoy your work and have few skills

(2013·辽宁高考)Going gree ( http: / / www.21cnjy.com )n seems to be a fad (时尚)for a lot of people these days.Whether that is good or bad，we can't really say，but for the two of us，going green is not a fad but a lifestyle.www-2-1-cnjy-com
On April 22，2011，we de ( http: / / www.21cnjy.com )cided to go green every single day for an entire year.This meant doing 365 different green things，and it also meant challenging ourselves to go green beyond the easy things.Rather than recycle and reduce our energy，we had to think of 365 different green things to do and this was no easy task.

We have learned inf ( http: / / www.21cnjy.com )ormation about global warming，whether in school，from TV programs，or by overhearing the adults around us.The pieces of information and facts are everywhere，but where on earth does global warming come from？How does it relate to our lives？And what can we do to help
Let's check out T ( http: / / www.21cnjy.com )he Down to Earth Guide to Global Warming，written by Americans Laurie David and Cambria Gordon.In the book，the concept of sustainability(可持续性的概念)is compared to the love of your pet.“Even though your cat might pee(撒尿)on your bedspread or your dog might chew your favourite shoes，you still keep it．You don't throw it away.”The planet is also compared to your messy room，and CO2 and temperature“go together like peanut butter and jelly(果酱)”．
While a mere one ( http: / / www.21cnjy.com ) degree increase in world temperature might seem small，a comparison of a popsicle(冰棒)you can lick(舔)and one you’d have to drink may make your concern for global warming grow.
The book，constructe ( http: / / www.21cnjy.com )d from 100 percent recycled paper and printed with soy(黄豆)inks，has a chapter“What you can do to stop global warming”．There are tips you might have already known，but the book has more interesting ideas.For example，leading an unplugged(不通电的)life for a day，or considering your career ambitions in light of climate change.From hydrologist(水文工作者)to biofuel(生物燃料)engineer，they are careers that are sustainable and can be realized.
“Kids are the num ( http: / / www.21cnjy.com )ber one influence on their parents.They are guides of change，”said author David.

Generations ( http: / / www.21cnjy.com )of children grew up reading comic books secretly, hiding out from parents and teachers who saw them as a waste of time and a risk to young ics are now gaining a new respectability at school. That is thanks to an increasingly popular and creative program, often aimed at struggling readers, that encourages children to plot, write and draw comic books, in many cases using themes from their own lives.
The Comic Book Pr ( http: / / www.21cnjy.com )oject was started in 2001 by Michael Bitz at an elementary school in Queens. Since its creation, the program, which is mainly conducted after school, has spread to more than 850 schools across the country. It has gotten a big push from the Canent craze among adolescents for comic book clubs and for Manga, a wildly popular variety of comic originating in Japan.
The point is ( http: / / www.21cnjy.com ) not to drop a comic book on a child's desk and say: “read this”. Rather, the workshops give groups of students the opportunity to collaborate(合著) on often complex stories and characters that they then revise, publish and share with others in their communities.
Teachers are find ( http: / / www.21cnjy.com )ing it easier to teach writing，grammar and punctuation with material that students are fully invested in. And it turns out that comic books have other built－in advantages. The pairing of visual and written plotlines that they rely on appear to be especially helpful to struggling readers. No one is suggesting that comic books should substitute for traditional books or for standard reading and composition lessons. Teachers who would once have dismissed comics out of hand are learning to exploit a style that clearly has a powerful hold on young minds.They are using what works.
52．Which of the following is probably the BEST title of the passage
A．Japanese Comic Books.
B．Comic Books in the Classroom.
C．Reading Efficiently.
D．A Current Craze.
53．Which of the following is TRUE according to the passage
A．Students' read ( http: / / www.21cnjy.com )ing materials are often involved with their daily life.
B．Comic books can now take the place of textbooks at school.
C．Teachers now give away comic books for children to read.
D．Children's imagination plays a key role in comic books.
54．The underlined ( http: / / www.21cnjy.com ) phrase “its” in Paragraph 2 probably refers to________．
A．the Comic Book Project's
B．an elementary school's
C．Queens'
D．the country's
55．It can be inferred that________．
A．comic books were first used in Japanese schools
B．parents hav ( http: / / www.21cnjy.com )e different opinions about their children reading comic books
C．more and more teachers will realize the advantages of comic books
D．comic books will be allowed to enter all the schools in the country

Clean air is on ( http: / / www.21cnjy.com )ly made up of nutrition, oxygen and water. Our country has been industrialized; our cities have grown and traffic has increased. For these reasons there has come an increase in the number of byproducts released into the air, such as particles from burning fuels and poisonous gases from chemical reactions. These gases become pollutants.21cnjy.com
Air pollution has a ba ( http: / / www.21cnjy.com )d effect on the earth and our environment. Air pollution can result in acid rain, and it can also lead to the greenhouse effect－a condition in which pollution stops radiation from traveling out of the earth's atmosphere. Due to the greenhouse effect, the temperature on the earth becomes warmer, which is known as global warming. What's more, air pollution may produce holes in the ozone layer－this layer of ozone naturally keeps ultraviolet rays of the sun from reaching the earth. The holes make it possible for the rays to reach us.
Don't let all the ( http: / / www.21cnjy.com )bad news about air pollution get you down because there are many ways to help fight the air pollution. Every one of us can employ a variety of solutions to air pollution. A smoker can give up smoking. While shopping, you can choose organic and natural products. Driving less and carpooling more can also contribute to less pollution. Next time, keep your air conditioning low. Of course you can plant more trees.
Air pollutio ( http: / / www.21cnjy.com )n is a major problem for our planet. However, as long as we realize how serious the air pollution is and take action now, everyone can make a difference.

【语篇解读】 本文是记叙文。文章讲 ( http: / / www.21cnjy.com )述的是风靡全球的漫画人物“呆伯特”的创作者Scott Adams 在遇到挫折时，因受到鼓舞而坚持并最终获得成功的故事。对他来说，这份鼓励是一份永远无法偿还的礼物。
16．D
17．B 由段首的I was at ( http: / / www.21cnjy.com )tracted by...“Funny Business”以及下文的all my questions about drawing material and requirements for submission可知，“我”一直都想“进入(get into)”卡通业，“但(but)”却不知该从何处入手。
18．C “我”是偶然间看到这个节目的，因此是抄下“地址(address)”给主持人写信。
19．B 由下文的answering all my questions 可知，“我”向主持人杰克征询专业的“建议(advice)”。21·世纪*教育网
20．A 由下文的sayin ( http: / / www.21cnjy.com )g that my sample cartoons were...and worth publishing 以及I'm writing this note is to again encourage you可知，这是一封“鼓励(encouraging)”的信件。
21．C 由下文的But he ( http: / / www.21cnjy.com )went further，saying...的转折可知，杰克在夸“我”的漫画样品很棒，值得发表的同时，还“告诫(warned)”“我”最初的时候可能会遭到很多拒绝。
22．A 由worth publishing可知漫画样品很“棒(good)”。
23．B
24．D 受到鼓舞，“我”很“兴奋( ( http: / / www.21cnjy.com )excited)”，于是把最好的一些“作品(work)”寄给了两家著名杂志社。此处的work 指代cartoons。
25．C 由I gave it up as a bad job可知“我”被“拒绝(refused)”了。
26．B 被拒绝之后，“我”放弃了，没再在“卡通画(cartooning)”上作进一步的努力。
27．A “我”与杰克并不熟络，19年后能再次收到他的来信，“我”很“震惊(shocked)”。
28．B 作者只是杰克众多粉丝中的一个。杰克整理他的信件时，“偶然看到(ran across)”了作者的来信和卡通画。21*cnjy*com
29．D 由上文的answering all my questions可知。
30．B
31．C 由本句中的to again ( http: / / www.21cnjy.com ) encourage you 以及下句的I wish you lots of luck，sales，and good drawing可知，杰克再次来信是为了鼓励作者能“继续(keep)”画漫画，并把他的“想法(ideas)”画出来投给各个杂志社。ideas此处指画漫画的灵感、素材等。
32．D 根据本句的I took ( http: / / www.21cnjy.com )out my art brushes and set to work on the sample cartoons now known as“Dilbert”可知，自从“我”放弃画画后，“又一次(Again)”拿起了画笔。
33．A 由known as “Dilbert”可知，漫画“呆伯特”很“成功(successful)”。
34．B 两封鼓励信对于杰克来说仅仅只是朴实简单的“善意之举(act of kindness)”，而对作者却产生了很大的影响。 21*cnjy*com
35．C eventually与上文 ( http: / / www.21cnjy.com )的I hadn't even thanked him for that first letter相呼应。“我”最终向“我”的朋友表达了“谢意(thank)”。
36．B 主旨大意题。文章围绕话题“我们是依靠电脑还是应该手写”展开，故答案选B。
37．B 细节理解题。由第四段“I ( http: / / www.21cnjy.com )t's faster and easier to correct if using a computer.”和第七段“Now that it's more convenient and efficient to write on a computer，why bother to handwrite？”可知学生依赖电脑是因为使用电脑方便、快捷、修改容易。
38．B 词义猜测题。结 ( http: / / www.21cnjy.com )合上文的computer dependence和下文的表述，不难推出taking stock in意为“相信，依靠”。故B项正确。
39．C 推理判断题。最后 ( http: / / www.21cnjy.com )一段介绍：北京许多小学已把书写课规定为必修课，在大学里，有些教授要求学生交手写的作业和论文。由此我们可以得出结论：今后越来越多的学生会重视书写。故C项为正确答案。
40．D 细节理解题。根据第一段 ( http: / / www.21cnjy.com )．..as humans we all feel that we must be here for a purpose.可知，答案为D。
41．C 推理判断题。根据第二段S ( http: / / www.21cnjy.com )omehow we seem to hang onto our failures and limits more than we do our success，which is just human nature可推断，答案为C。
42．B 作者意图题。根据第三段I ( http: / / www.21cnjy.com )had a purpose and passion so I made it at last 可推断，答案为B。
43．A 细节理解题。根据第四段． ( http: / / www.21cnjy.com )..your purpose must be in the area that you love，enjoy and are passionate about...可知，答案为A。
【语篇解读】 本文为记叙文。2011年 ( http: / / www.21cnjy.com )4月22日，“我们”夫妻二人决定每天都追求一种绿色的生活方式，并且要坚持一整年。这意味着“我们”要做365件“绿色的”事情，这对“我们”来说是个挑战。最后，“绿色之年”改变了“我们”的思维，“我们”很感激有这个机会，也坚信“我们”确实有能力保护我们的地球。
44．A 主旨大意题。概括文章大 ( http: / / www.21cnjy.com )意可知，文章主要介绍了我们夫妻二人追求绿色生活方式的行为。在本文中going green为关键词，可概括文章主旨。B项概括范围过大；C项意为“保持思维开放”，曲解了文章主旨；D项意为“庆祝我们的绿色之年”，概括范围过小。
45．D 推理判断题。根 ( http: / / www.21cnjy.com )据第二段的最后两句可知，整整一年都要过绿色的生活，不是件容易的事情，因为这不仅意味着要做365件不同的“绿色的”事情，还意味着除了一些简单的事情，我们还要不断地挑战自己，追求环保。这些都是不寻常的(unusual)环保任务，D项与之意思一致。文章并未提及其他几项内容。
46．A 细节理解题。根据倒数第二段可知 ( http: / / www.21cnjy.com )，在这一年里，我们完全改变了生活方式，做每一件事都追求环保、绿色，否则就要接受惩罚，所以A项正确。B项意为“他们无视他人不环保的行为”，与倒数第二段最后一句矛盾；C项意为“他们选择更好的化学清洁剂”，与倒数第二段的“Our home is kept clean by vinegar and lemon juice，with no chemical cleaners.”表达意思不一致；D项意为“他们出售自制的食品”，与倒数第二段的倒数第二句不一致。
47．B 推理判断题。最后一段指 ( http: / / www.21cnjy.com )出，我们的思维已经发生了变化，我们坚信自己有能力改变一些事情，保护我们的地球，由此可知，我们会继续自己的这种绿色生活方式。故B项正确。文章并未提到“政府会支持这个绿色计划”“有人和这对夫妻持有不同观点”或者“绿色之年正成为一项全国性活动”，故排除其余选项。
48．B 推理判断题。由文章第一段末尾三个连续的特殊疑问句可以推出作者通过提问开篇。故选B。
49．D 词义猜测题。阅读分析画线词所在句及上下文可知，作者把可持续发展的概念比作对小猫和小狗两个宠物的爱，可见it指小猫或小狗。
50．A 细节理解题。由文章第二段末句可知答案。
51．A 推理判断题。由文章第四 ( http: / / www.21cnjy.com )段“For example，leading an unplugged life for a day，or considering your career ambitions in light of climate change”可以推出作者举了书中的两个例子作为如何阻止全球变暖的建议。
52．B 主旨大意题。第 ( http: / / www.21cnjy.com )一段提出全文主题：Comics are now gaining a new respectability at school.之后围绕该主题具体介绍漫画在学校教育中的意义和利用，由此判断全文标题应该是：教室中的漫画。故选B项。
53．C 细节理解题。根据最后 ( http: / / www.21cnjy.com )一段“Teachers are finding it easier to teach writing，grammar and punctuation with material that students are fully invested in(投入)．And it turns out that comic books have other built－in advantages.”可知老师给学生提供漫画书让他们阅读，故选C项。
54．A 词义猜测题。第二段第一、二句的逻辑顺承关系可推断“its”应指the Comic Book Project's，故选A项。
55．C 推理判断题。根据最后一段对“漫画教学”的优势的介绍可推断，越来越多的人会意识到漫画书的好处。故选C项。
56．Pollution 57 ( http: / / www.21cnjy.com ).Causes/Reasons 58.growth/growing 59.acid 60.warming 61.Solutions 62.smoking 63.carpool 64.Conclusion 65.seriously

Climate chang ( http: / / www.21cnjy.com )e will force exhausted birds migrating to Europe from Africa to travel further with possibly disastrous consequences，according to a study.
The annual v ( http: / / www.21cnjy.com )oyage of some species，which fly north in search of food and suitable habitats，could increase by as much as 400 kilometers(250 miles)，the research found.“Marathon migrations for some birds are set to become even longer，”said Stephen Willis, a professor at Durham University in Britain and the main architect of the study.“This is bad news for birds like the Whitethroat，a common farmland bird.The added distance is a considerable threat.As temperatures rise and habitats change，birds will face their biggest challenge since the Pleistocene era(更新世：始于距今180万年)，which ended 11，000 years ago，”he said in a statement.【来源：21·世纪·教育·网】
Some 500 mil ( http: / / www.21cnjy.com )lion birds migrate each year from Africa，some weighing as little as nine grams. (three－tenths of an ounce)．To complete a voyage that can be thousands of kilometers long.birds have to fatten themselves up to twice their normal weight.Some even shrink their internal organs (收缩内脏)to become more fuel efficient，so any additional distance may be dangerous. 21*cnjy*com
The study finds that f ( http: / / www.21cnjy.com )rom 2071 to 2100，nine out of 17 species examined are going to face longer migrations，particularly birds that cross the Sahara Desert.Some birds traverse the Sahara and the Mediterranean Sea in a one－go，while others have a break in northern Africa before crossing.Many fly at night，when temperatures are cooler.【版权所有：21教育】
A few—such as the B ( http: / / www.21cnjy.com )lackcap—have started to adapt by spending winters in Britain，but such behaviour remains exceptional，the study said.The study forecasts that the migration distance of the Orphean Warbler will jump from 2，700 kilometers(1，700 miles)to between 3，050 and 3，350 kilometers(1，900 and 2，1 00miles)，with even longer increases for the Subalpine and Barred Warblers.
