8.Britain's seed bank,the only one in the world aiming to collect all of the planet's wild plant species,has reached its goal of banking 10 percent by 2010.
The Millennium Seed Bank Project,run by Kew Gardens-one of the oldest botanical gardens-will officially deposit the 24,200th species on Thursday,a pink,wild banana from China.
More than 50 countries are now on board with Kew's giant task but vast places of the globe,including India and Brazil,still need to join in and donate seeds,director Paul Smith said.
The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds.Its goal is to help protect the planet's bio-diversity during a time of climate change.
The wild banana seed is under threat of extinction(灭绝) in southwest China from agricultural development.It is a vital food source for Asian elephants and important for growing bananas for human consumption.
Stored at minus-20 degrees centigrade,so they can last for thousands of years,the seeds await the day that scientists hope never comes-when the species no longer exist in the wild.
It is a race against time,Smith said,because in the last decade alone,20 plants held in the bank have already been wiped out in the wild.He estimates that between a third and a quarter will become extinct this century.
"It is urgent and it is happening now.An area,the size of England,is cleared of primary vegetation(植被)every year."Smith said.
Because most of the world's food and medicines come from nature,protecting wild plant species is quite important,scientists say.There are already many other seed banks safeguarding food crops,which only account for 0.6 percent of plant diversity.
For Kew's next goal-to collect a quarter of wild varieties by 2020-the botanists need 10 million pounds a year,or a further 100 million pounds on top of the 40 million they have already been granted.
56.What's the final purpose of the Britain's seed bank?C
A.To collect enough money for the project.
B.To safeguard food crops.
C.To protect wild plants from extinction.
D.To help scientists study wild plants.
57.The wild banana seed in China is in danger because ofA.
A.the expanding of farming work          
B.the climate change in this area
C.the large number of Asian elephants      
D.human's large consumption
58.We can learn from the passage thatB.
A.the seeds in the bank can be used now and then all over the world
B.India and Brazil haven't joined in the Seed Bank Project at present
C.there is only one seed bank in the world at present
D.the wild plants in places like India and China will never die out
59.What does the underlined word"it"in paragraph 7 refer to?B
A.The extinction of plant species.
B.The Millennium Seed Bank Project.
C.Britain's seed bank.
D.Kew Gardens'next goal.
60.Which of the following information isn't mentioned in the passage?C
A.The global partnership of collecting wild plant species.
B.The temperature condition of the conservative wild plant species.
C.The government's financial support for the seed bank project.
D.Scientists'concern on the extinct wild plant species.

分析 本文为环保类文章,介绍了英国种子公司为保护濒危野生植物所做出的举措及它们的最新进展.

解答 56---60 CABBC
56.答案C.细节理解题.由第一段"Britain's seed bank,the only one in the world aiming to collect all of the planet's wild plant species"和第四段"The wild banana seed is under threat of extinction(灭绝) in southwest China from agricultural development"可知,伦敦种子银行旨在通过收集自然界的植物种子以达到保护自然界生物多样性的目的.
57.答案A.细节理解题.由第四段第一句"The wild banana seed is under threat of extinction(灭绝) in southwest China from agricultural development"可知,这种香蕉在中国西南部面临灭绝是因为农业的发展,故本题选A项.
58.答案B.推理判断题.由第二段Paul Smith的话"More than 50 countries are now on board with Kew's giant task but vast places of the globe,including India and Brazil,still need to join in and donate seeds,director Paul Smith said"可知,印度和巴西还没有参与59.种子银行捐种子的活动,故选B项.其他三项与文章内容不一致.
59.答案B.细节理解题.本文主要讲的是伦敦种子银行和它所进行的"千年种子库计划",结合It所在句子可知,是这项计划在和时间赛跑,故此题选B.
60.答案C.细节理解题.文章最后一段"For Kew's next goal-to collect a quarter of wild varieties by 2020-the botanists need 10 million pounds a year,or a further 100 million pounds on top of the 40 million they have already been granted",只是说实现下一个目标植物学家每年还需要很多资金,并没提到政府的财政支持.

点评 健康环保类文章可分为三部分:第一部分一般是文章的首段,主要用来提出文章的主题,即文章想要阐述、说明的主要内容;第二部分是文章的主体,可由若干个段落组成,对文章的主题进行展开说明;第三部分是结尾段,对文章的主题进行归纳总结.这类文章多用一般现在时,而且一般多使用客观性词语表述.有时为了强调客观性,也常使用被动语态.
从近几年的考试题来看,科普环保类的文章越来越与人们的实际生活相接近.由于此类文章缺乏故事情节,很多同学对此类文章感到费解.但一般的科普类文章都是就事论事,需要逻辑推理和想象的时候较少,因此此类阅读题也没有同学们想象中的那么难,只要多加训练,就能较好地答题.

11.People and the sources of air pollution are found in the same places.This means that cities with large populations have the biggest problem of dirty air.Air pollution is caused by many different things.A major source of air pollution is the gas fumes (烟雾) from cars.Statistics show that 93percent of all auto trips are within cities.Another major source of dirty is the burning of coal and oil for energy.This energy is needed to make electricity.Of course,much more electricity is used in the city than in the countryside.
On the average,we throw away more trash and garbage than the year before.The burning of garbage contributes to air pollution.Many major industries are also responsible for the dirty air in the around cities.The fumes from iron,steel,chemical,and petroleum (石油) production add particles (微粒) to the air.
The effects of air pollution range from loss of clear vision,mild headaches to death.Wherever coal and oil are used for fuel,fumes may kill trees and plants and cause metal to corrode (腐蚀).In some larger cities,these fumes endanger the life of human beings by contributing to lung diseases and causing early deaths.

28.The key point of the passage is thatB.
A.the cause of air pollution is people
B.the causes and the effects of air pollution are both found in cities
C.the effects of air pollution range from headaches to deaths
D.air pollution is caused by dirty air
29.What is the purpose of this passage?A.
A.To persuade people to stop polluting the air.
B.To tell the causes of air pollution.
C.To tell why cities have larger populations.
D.To describe why cities are bad places to live.
30.Why is air pollution heavier in the city than in the countryside?D.
A.Because there are more people in cities.
B.Because the air in the city is dirty.
C.Because there are more cars in the city.
D.Because there are much more gas fumes from cars and burning of coal and oil for energy in the city than in the country.
31.In larger cities,the fumes from coal and oil may result inC.
A.heart disease
B.serious headache
C.lung disease
D.loss of clear vision.
16.Welcome back to the hot topic of studying abroad!Last time,we talked about the general"soft-ware"needed to have a (61)successful(success)  studying experience overseas,(62)whichrefers to the ability to understand western culture,and problem solving skills when (63)facing(face)  critical situations,etc..
Now,1will dig deeper into the concept of software".Everyone is talking about culture shock nowa-days,but you may wonder what it actually (64)means(mean).Simply put:culture shock is the diffi-culty people may experience when being exposed and adjusting to a (65)remarkably (remarkable)  different new culture.Usually,people often go (66)throughfour distinct phases:the honeymoon phase,the ne-gotiation phase,the adjustment phase and the mastery phase.Culture shock can happen immediately upon your (67)arrival(arrive)  in the country.
For international students,perhaps the most direct impact of culture shock is the variety of accents,especially in multicultural countries (68)likethe U.S.Canada or Australia.There are two main reasons:Firstly,these countries have highly diversified groups of residents from different cultural (69)backgrounds(background).Secondly,there are many international students from all around the world every year studying in these countries,so you shouldn't be surprised (70)to find(find) all kinds of unfamiliar accents around the university campus.

13.Helsinki is offering young people the chance to rent a cheap apartment in an old people's home,if they agree to spend time socialising with the elderly residents.
The city council is seeking applications from renters under the age of 25 who will commit to spending between three and five hours each week with their older neighbours,at a care home in the eastern Laajasalo district.In exchange,they'll get a studio flat measuring 23 square meters with a private kitchen,bathroom and balcony for 250 euros per month.
Currently only three flats are available.but the scheme is part of a wider effort to deal with a lack of accommodation for young people in the capital.Ordinarily a studio costs about 600 euros a month,depending on the area,one local university advises.
Those who apply don't need any specific care experience."There are staff to look after the elderly."project manager Miki Mielonen tells Yle."We are looking for young people who maybe have a different perspective on everyday life,who will bring variety and recreation to the elderly residents."
More than 60 people have applied for the spaces in less than a week,and the idea has also been widely recognized by Finns on social media."Great project,hopefully it will spread to other areas,"writes one person on Facebook,while another applauds the scheme for bringing different generations together.
But some wish it was open to more people,with one user saying:"It's a shame the flats are so small.It would have been nice if the elderly had a small family with children or a single parent as their neighbour."And one person has a different opinion about the cut-off age,writing:"Shame I'm too old for this-I would have surely applied."
24.One can probably get the cheap apartment if heC.
A.reaches the age of 25               
B.has financial problems
C.promises to accompany the elderly   
D.agrees to share it  
25.Why is the new rent scheme accepted?A
A.It can benefit both young and old.   
B.It doesn't need any professional training.
C.The flats are well-equipped.          
D.Big apartments are in short supply.
26.What does the underlined sentence suggest?C
A.He doesn't want to grow up.
B.He has a chance to apply again.
C.He disapproves of the age limit.
D.He applies for the flat without hesitation.
27.What would be the best title of the text?A
A.Young Finns offered cheap flats at care home
B.New apartments designed for the elderly
C.A new approach to caring for the old
D.A good chance for the needy families.
20.Allen goes everywhere with Brigitta Anderson,a 54year-old secretary.He moves around her office at work and goes shopping with her."Most people don't mind Allen,"says Brigitta,who thinks  he  is wonderful."He is my fourth child,"she says.She may think of him and treat him that way,buying him delicious food,paying his health bills and his taxes,but in fact Allen is only a dog.
Brigitta and Allen live in Sweden,a country where everyone is expected to lead an orderly life according to the rules laid down by the government,which also provides a high level of care for its people.Yet,this level of care costs a lot of money.
People in Sweden pay taxes (税) on everything,so they aren't surprised to find that owning a dog means some more taxes.Some people are paying as much as 500Sweden kronor in taxes a year for the right to keep their dogs.Money from dog taxes is spent by the government on dog hospitals and sometimes medical treatment for a dog that falls ill.However,such a treatment is expensive,so dog owners often decide to pay health insurance (保险) and some even buy life insurance for their dogs.
In Sweden,dog owners must pay for any damage their dogs do.A Swedish kennel (养狗场) club official explains what this means:if your dog runs out on the road and gets hit by a passing car,you,as the owner,have to pay for any damage done to the car,even if your dog has been killed in the accident.

21.What is the passage about?B
A.Owning dogs is not allowed in Sweden.
B.Owning dogs costs a lot more in Sweden.
C.You are required to pay life insurance for your dog by law if you own one in Sweden.
D.Allen is a good dog.
22.The money paid as dog taxes is used toC.
A.keep a high level of care for people  
B.pay for any damage done by dogs
C.provide medical care for dogs  
D.buy insurance for dog owners
23.From the text it can be inferred that in SwedenA.
A.people care much about dogs
B.dogs are not allowed to go out without their owners
C.many car accidents are caused by dogs
D.dogs are not welcome in public places
24.If a dog causes a car accident and gets killed,who should pay for the damage done to the car?B
A.The owner of the car.        B.The owner of the dog.
C.The insurance company.       D.The government.
25.What does the underlined word"he"in the first paragraph refer to?D
A.Brigitta.           B.Secretary.
C.Anderson.           D.Allen.
