Last month ,studenrs from 103 universities in 88 coontries took part in international computer programming contest. The Battle of the Brain took place in Harbin, China. Three---person terms from each school had hours to solve eleven real world problems.
Jerry Cain coached the team from Standford University in Palo Alto,California. He says the problems involved, among other things, paperweights, robots, castles and lakes.
JERRY CAIN: “One of the programming problems was trying to figure out how to break an chocolate bar into a certain number of pieces of a certain number of sizes and to do it as quickly as possible. And that’s probably the simplest of all them.”
The students first listed the problems in order of difficulty and then they wrote the needed software systems. They designed ways to test their solutions. And they wrote the needed software systems , Even the winning team from Shanghai Jiaotong University in China was not able to solved all the problems within the given time limit. Stanford’s team solved five problems and finished in fourteenth place. Standford was one of twenty---one America universities that took part in the conest this year. The conest began in 1970 at Texa A and M University. The first final competition was held in 1977 at the Association for Computer Machinery Computer Science Conference. It developed and grew as more and more schools took part in local and area contests.
Contest spokenman Doug Heintzman says the world champions receive prizes and scholarships. They are also guaranteed an offer of employment or practice period with IBM. “We’re had past world champions that IBM has given a post to in our Zurich research Iaboratory and they are now working on some of the Ieading edge materials in science and physics. So this competition is an opportunity to be recognized and to be recruited by some of the top technology and firms around the world “

They say that before long,we will be able to receive more than 500 television networks on cable or by satellite .Some people think that it"s ridiculous to have that many channels.Their usual criticism goes something like this:
“I already get more channels on my TV than I have time to watch.No one needs to see that much TV.There’s not enough time in the day to watch all that!”They also state that most of what’s on television now isn’t worth watching in the first place.
I think they’re missing the point.If the local library wanted to add another 5,000books,would
we say“That’s silly,we’ll never have time to read all those books.”?The point is that we would
have more choices.
I don’t believe that most people should watch more television And if we had 500 or even 1,000 channels to choose from,we wouldn’t have to spend more time watching the tube.We would.however,have a better selection of programs to choose from.That means that the quality of our viewing time would improve.
I,for one,say that the more channels we can access,the better,Give me more choices! If they’re not worth my time,I’ll just hit the“off”button.

For millions ofpeople,the American dream ofowning a home seems to be slipping out of
reach.
“Maybe young couples can no longer afford to buy a ready-made house as their parents did,"’
says 40-year-old building instmctor Pat Hennin.“But they can still have a home.Like their pioneer ancestors,they can build it themselves,and at less than half the cost of a ready-made house.”
The owner-builders came from every occupational group,although surprisingly few are professional building workers.Many take the plunge with little or no experience.“l learned how to build my house from reading books,”says John Brown,who built a six-room home for$25,000 in High Falls,New Jersey.“If you have patience and the carpentry(木匠)skill to make a bookcase,you can build a house.”An astonishing 50 percent of these owner builders hammer every nail.1ay every pipe,and wire every switch with their own hands.The rest contraet(承包)for some parts of the task.But even those who just act as contractors and finish the insides of their homes can save from 30 percent to 45 percent ofwhat a ready-made home would cost.
One survey revealed that 60 percent ofowner-builders also design their homes.Many others
buy commercial house plans for less than $100 or use plans available from the U.S. Department ofAgriculture.

Birds in cities are damaging their health by trying to sing above the noise of urban life.
New research shows that male birds are trying to compete against traffic and city sounds.They are now singing louder and at higher frequencies,which could harm their vocal cords.Some birds are choosing to sing at night instead of dudng the day.This makes them more open to attack and also creates stress and exhanstion.
“The difference between urban and rural birdsong is becoming so big that the two groups could now be unable to communicate.This could lead to inbreeding and a weak gene pool.”said Dr Sue Anne Zollinger of the University of St Andrews.
According to Zollingar,a bird group with a small geae pool might adapt less quickly to new diseases and could be wiped out.
A study of the dawn chorus found that birds in Berlin sang up to 14 decibels(分贝)louder than those in the forest.The birds sang loudest on weekday momings.
“By trying to sing over the sound of the city,birds are rising vocal injury,”said Zollinger.“All this puts the sarne strain on a bird’s vocal cords as when ahuman need to shout to be heard—except the birds are doing it all day,every day,”she said.
“Singing under such pressure means birds have less control over the sound they produce. Their songs may lose quality and become more rough—sounding.”said Zollinger.This could make them appear less attractive to female birds.
Mark Constantine,author of The Sound Approach to Birding,said:“Birdsong is important for our quality of life and has been proved to reduce our blood pressure.When we live in the centre of large,urban areas,we get stressed and it"s extremely good to have birdsong around us.The impact on humans of birdsong is massive.It harms us,as well as the birds,if their songs become louder and simpler
53.Some birds in cities now choose to sing at night time because_______.
A.they want to attract more birds of opposite sex
B.they are more likely to be discovered by their family
C.they can’t adapt to the loud noises during the daytime
D.they have to frighten their enemy away
54.According to the passage,urban and rural birds might not be able to_______.
A.recognize each other
B communicate with each other
C live with each other
D.compete against each other
55.It requires greatest efforts for birds in cities to sing o_______.
A.Monday nights B.Wednesday afternoons
C.Saturday Evenings D.Friday momings
56.According to Dr Sue Anne Zollinger,birds singing louder might eventually lead to_______.
