20.Sunny countries are often poor.A shame,then,that solar power is still quite expensive.Eight 19,a British company by Cambridge University,has,however,invented a novel way to get round this.In return for a deposit of around dollar 10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity,a battery that can deliver a three amp(安培) current to store this electricity,and a lamp whose bulb is a light-emitting diode(二極管).The firm thinks that this system,once the battery is fully charged,is enough to light two small rooms and to power a mobile-phone charger for seven hours.Then,next day,it can be put outside and charged back up again.
The trick is that,to be able to use the electricity,the system's keeper must buy a scratch card-for as little as a dollar-on which is printed a reference number.The keeper sends this reference,plus the serial number of the household solar unit,by SMS to Eight19.The company's server will respond automatically with an access code to the unit.
Users may consider that they are paying an hourly rate for their electricity.In fact,they are paying off the cost of the unit.After buying around dollar 80 worth of scratch cards-which Eight19 expects would take the average family around 18 months-the user will own it.He will then have the option of continuing to use it for nothing,or of trading it in for a bigger one,perhaps driven by a 10-watt solar cell.
In that case,he would go then through the same process again,paying off the additional cost of the upgraded kit at a slightly higher rate.Users would therefore increase their electricity supply steadily and affordably.
According to Eight 19's figures,this looks like a good deal for customers.The firm believes the average energy-starved Kenyan spends around dollar 10 a month on oil-enough to fuel a couple of smoky lamps-plus dollar 2 on charging his mobile phone in the market-place.Regular users of one of Eight19's basic solar units will spend around half that,before owning it completely.Meanwhile,as the cost of solar technology falls,it should get even cheaper.

D.Return it to the company.
43.How much would users pay for the cell and scratch cards before they own a 2.5-watt solar cell?C
A.Around 10. B.Around  80. C.Around 90. D.Around 180.
44.It can be inferred from the last paragraph thatB.
A.Kenyan families would find it difficult to afford the solar cell

C.few Kenyan families use mobile phones for lack of electricity
D.the company will make a great profit from selling solar cells
45.What might be the most suitable title for the passage?A
A.Solar Energy:Starting from Scratch.

8.Lost in the Post
How would you feel if the letter you penned carefully and posted to your favorite star ended up in the recycling bin?That's where unopened fan mail sent to singer Taylor Swift was found in Nashville.(71)G
Swift's management said it was an accident,but dealing with piles of letters is a burden for most public figures.According to te BBC reporter Jon Kelly,at the height of his fame,Johnny Depp was said to receive up to 10,000letters a week.(72)C
The dawn of the digital age in which public figures with a Twitter account can be messaged directly has made the process easier.The White House says it deals with 20,000messages addressed to President Barack Obama each day.
Some celebrities don't want letters.In 2008,Beatles drummer Ringo Starr said that he would throw them out because he was too busy.(73)A Robert Pattinson,star of the Twilight films,claims that he reads tonnes and tonnes of letters from fans,which takes up almost all his free time.
Many artists,however,outsource(外包) the task of opening,reading and replying.Sylvia"Spanky"Taylor,58,has run a service in California that does just that since 1987.(74)F Most letters are simply declarations of affection and admiration,she says.A few ask for money.A small number contain threats which require her to contact the celebrity's security team and law enforcement.
The biggest problem for Taylor is working out how to deal with the correspondence(通信).Presents such as soft toys are sent to local hospitals,and most of the letters just get shredded and recycled.
(75)D For some,this is enough,according to Lynn Zubernis,an expert at West Chester University.She says that the relationship between fan and celebrity may exist only in the mind of the former but it comes from a deeply-rooted human need for community.

A.Others do attempt to get through it themselves.
B.In fact,there is no alternative to deal with the problem.
C.How could he have enough time to skim through these letters one by one?
D.Typically,correspondence is acknowledged by a photo with a printed"signature".
E.Accordingly,the correspondence problem has been difficult for the computer to automate.
F.She and her staff deal with up to 20,000items of mail a month on behalf of 26celebrities.
G.This incident has caused a wide public concern about how the public figures deal with the   letters or mails from the fans.

15.Nowadays more and more people are trapped in too busy work to relax themselves.We have no time to tell a bed-time story to our children,or enjoy a nice dinner with our family,or take a break to think about how we live the precious life,or even meet friends.All we notice is that the distinctions that used to guide and steady us-between Sunday and Monday,public and private,here and there-are gone.We have more ways to communicate,but less and less to say.Partly because we're so busy communicating.
Maybe that's why more and more people I know,even if they have no religious commitment,seem to be turning to yoga,or meditation,or tai chi.Some friends of mine try to go on long walks every Sunday,or to"forget"their cellphones at home.A series of tests in recent years has shown that after spending time in quiet rural settings,subjects"exhibit greater attentiveness,stronger memory and generally improved cognition.Their brains become both calmer and sharper,"More than that,sympathy,as well as deep thought,depends on neural processes that are"inherently slow,"the very ones our high-speed lives have little time for.
In my own case,I turn to unusual and often extreme measures to try to keep my good sense and ensure that I have time to do nothing at all.I've not yet used a cellphone and I've never tweeted or entered Facebook.I try not to go online till my day's writing is finished,and I moved from Manhattan to rural Japan.
None of this is a matter of principle or asceticism (苦行主義):it's just pure selfishness.Nothing makes me feel better,calmer,clearer and happier than being in one place,absorbed in a book,a conversation,a piece of music.It's actually something deeper than mere happiness:it's joy,which the monk David Steindl-Rast describes as"that kind of happiness that doesn't depend on what happens."That is the highest of the highest we have been longing for~The Joy of Quiet.

43.The writer sometimes doesn't do anything becauseD.
A.he is out of work
B.whatever he does make no sense
C.he is worried about his writing
D.he can enjoy himself in his leisure time
44.When the writer uses the word"forget",his real meaning isB.
A.somebody really forgets his cellphone at home
B.somebody leaves his cellphone at home on purpose
C.somebody hates modern techniques such as the cellphone
D.somebody thinks cellphone is not a suitable means of communication
45.The underlined word"distinctions',meansC.
A-outcome
B.similarity
C.difference
D.complication
46.What is the main idea of the article?A
A.It is important to spend time in quiet circumstances.
B.We can do some sports such as yoga to relax.
C.Principle or asceticism is important in one's life.
D.The more we communicate,the more we will be closer.

12.Daily Telegraph-An enormous number of sardines (沙丁魚) have been photographed as they swam in the formation of a dolphin (海豚).Steve De Neef photographed the fish near Cebu in the Philippines grouping together to protect themselves from larger animals.He said:"Getting the picture of the dolphin shape was just about being in the right spot at the right time,but it would be to their benefit if they could imitate (模仿) a larger animal."
Daily Mail-Black garlic-a sweet variety of the popular cooking ingredient that doesn't leave you with bad breath-is getting ready to hit the UK supermarket shelves.Black garlic tastes much sweeter than traditional garlic and enjoys twice the amount of anti-oxidants (抗氧化劑) and can last twice as long on the shelf.
BBC-Researchers in the United States have developed the first wirelessly controlled device (裝置) that can supply a drug directly into the body.A small chip is implanted under the skin.It contains the medicine,which it releases at programmed times.The developers say the device could improve the lives of millions of people who take medicine for long-term illnesses and may one day free patients from having to remember to take their medicine,or give themselves injections.
VOA-Global warming could make humans shorter,warn scientists who claim to have found evidence that it caused the world's first horses to shrink nearly 50 million years ago.As temperatures went up their size went down,and vice versa (反之亦然); at one point they were as small as a house cat.The scientists say that the current warming could have the same effect on mammals,and even humans.
