Last month, students from one hundred and three universities in eighty-eight countries took part in an international computer programming contest, which took place in Harbin, China. Three-person teams from each school had five hours to solve eleven real world problems.
The students first listed the problems in order of difficulty. Then they figured out the requirements of each. 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 solve all the problems within the given limit. Stanford’s team solved five problems and finished in fourteenth place. Stanford was one of twenty-one American universities that took part in the contest this year.
The official name of the Battle of the Brains is the ACM International Collegiate Contest. The first final competition was held in 1977 at the Association for Computer Machinery Computer Science Conference. Today, a network of universities holds area competitions that send the winners to the world finals, now organized by IBM.
Contest spokesman Dong Heintzman says the world champions receive prizes and scholarships. They are also guaranteed an offer of employment or internship(实习) with IBM. He said, “We have had past world champions that IBM has gone and employed in our Zurich research laboratory and are now working on some of the leading edge materials in science and physics. We have a world finalist from China who’s been working on the Watson Supercomputer that in the near future will be playing Jeopardy(一种超级计算机名称)against the best Jeopardy players in the world. So this competition is an opportunity to be recognized and to be recruited(招聘) by some of the top technology and research firms around the world.”

A．3

B．88

C．246

D．a lot of

In 2004，the World Health Organization，WHO，warned of a possible outbreak of another serious disease which may be even more deadly than SARS．The WHO believes that it is likely that bird flu will spread to human beings in the next few years．If it does，up to seven millions people could die from the disease．
Diseases like bird flu are caused by viruses，that is，tiny things which change and be come more dangerous over time．When a new type of a common virus changes，it may be able to get past the body’S immune system．If that happens，humans are in great danger until a cure or treatment becomes available．
There have always been viruses and people always get sick，of course，but as we saw with SARS，the situation is more difficult today．People travel more than ever before，which means that disease can spread quickly and across large areas——in fact the whole world．
Scientists are already working on drugs that will prevent or limit the effect of a new virus，but the process takes time．It is just as important to make sure that countries，especially poor countries，are prepared to deal with the disease。New disease usually affect poor areas the most，so we must help develop health care in all countries．

Researchers have found that cancer cells send out molecules different from those of healthy ones，and that might be sensed by smell by the highly sensitive dog’s nose．
For the study，five dogs were trained by a professional instructor to respond differently to breath samples of healthy and cancer patients．“The dogs learned to sit or lie down in front of cancer patient samples and to ignore control samples through the method of food reward，” McCulloch explained．
After a period of training，researchers tested the animals’ability to distinguish cancer patients from controls．The animals were given breath samples from 55 patients with lung cancer，3 1 with breast cancer and 83 healthy controls who were not included in the original training period．
McCulloch’s group found that the dogs were able to correctly distinguish the breath samples of cancer patients from those of the control subjects in about 90 percent of the cases．The dogs were also able to detecting early-stage lung and breast cancers．
“These results show that there is hope for early detection，”McCulloch said．The re-searches are planning to conduct further studies on the breath composition of cancer patients to possibly design an electronic device that can do the dogs’job．“A dog’s nose is so powerful it can detect odors（气味）10 000 to 100 000 times better than a human nose can．I hope people will be interested in doing this research，”McCulloch added，“It shows that there is definitely something out there．”
