Dogs are known for their sense of smell．They can find missing people and things like bombs and illegal drugs．Now a study suggests that the animal known as man’s best friend can even find bladder（膀胱）cancer．
Cancer cells are thought to produce chemicals with unusual odors（气味）．Researchers think dogs have the ability to smell these odors, even in very small amounts, in urine（尿）．The sense of smell in dogs is thousands of times better than in humans．
The study follows reports of cases where, for example, a dog showed great interest in a growth on the leg of its owner．The man was later found to be skin cancer．Carolyn Willis led a team of researchers at Amersham Hospital in England．They trained different kinds of dogs for the experiment．The study involved urine collected from bladder cancer patients, from people with other diseases and from healthy people．Each dog was tested 8 times．In each test there were 7 samples for the dogs to smell．The dog should signal the one from a bladder cancer patient by lying down next to it．Two cocker dogs were correct 56 percent of the time．But the scientists reported an average success rate of 41 percent．The British Medical Journal published the research．In all, 36 bladder cancer patients and 108 other people took part．During training, all the dogs reportedly even identified（认出）a cancer in a person who had tested healthy before the study．Doctors found a growth on the person’s right kidney（肾）．Carolyn Willis says dogs could help scientists identify the combined chemicals produced by bladder cancer．That information could then be used to develop machines to test for the chemicals．The team also plans to use dogs to help identify markers for other kinds of cancer．
49．What’s the general idea of the text?
A．Dogs have a good sense of smell B．Dogs can help cure cancer
C．Dogs can smell cancer D．Dogs help perform experiments

When the research on the effect of electric fields on E．coli was begun in 1962, it was essential that a biologist–specifically, a microbiologist–contributed to the project．She does not want her name used because she did not become a scientific researcher for fame, but rather for the challenge of putting pieces of a scientific puzzle together．
As a girl, she was inspired by the work of great scientists: she read the story of the cure of malaria in the Panama Canal; she also read a biography of Madame Curie．These accounts inspired her to pursue a career in scientific research．After high school, she worked for the Michigan Department of Health, where she did research in biology and microbiology．There, her colleagues saw her talent and encouraged her to pursue science as a career．She went on to earn a bachelor’s degree from Michigan State University in 1948 in medical technology．
When she began working at Michigan State in the early 1960s,
she was balancing the demands of scientific research with the needs
of her family．At that time both of her children were in school．She
would work in the lab in the morning while they were at school,
go home to see them at lunch, return to the lab for the afternoon, go
home for dinner, and return to the lab in the evening, if necessary．
At that time, there were fewer women scientists working than
there are today, but she encountered several in her career．At the
Michigan Department of Health, many of her colleagues were women and, consequently, she did not feel isolated because of her gender–nor did she feel that she was treated differently because she was a woman．
While working at Michigan State, she also felt that she was treated with respect by her peers．Her colleagues, among them doctors and Ph．D．chemists, all treated her as an equal．On the whole, she believes that there is not a great deal of difference between men and women in science．
56．Why does the woman scientist refuse to let out her name?
A．Because she is a shy lady．
B．Because she doesn’t mind her fame．
C．Because she never takes pride in her research．
D．Because she never works for her fame．
57．What is the noble lady scientist really interested in?
A．The life stories of other women scientists．
B．Biology and microbiology．
C．The secret of the success of the other scientists．
D．The difference between men and women scientists．

London—coffee protects mice from radiation and could get the same way in humans, according to Indian scientists.
Scientist at India’s Bhabha Atomic Research Center discovered that mice injected with caffeine (咖啡因)remained alive after high doses(剂量)of normally lethal radiation.
Although the study was limited to animals, Kachadillilli George, head of the research team, believes the findings could have implications (something suggested ) for humans .
“It does suggest that coffee might have some beneficial effects in protecting against radiation,” he told New Scientist magazine late last month.
George and his team injected 471 mice with caffeine and left them uncovered to 7.5 grays of gamma radiation(伽玛射线),enough to kill most mice. But 25 days later 70 percent of the mice that had received 80 milligrams(毫克)of caffeine per kilogram of body weight were still alive.
On the contrary all 196 mice that had been left uncovered to the same radiation but had not been given any caffeine died.
【小题1】George and his team drew the conclusion from .
| A．the magazine | B．their invention | C．the experiment | D．their experience |
| A．both mice and humans | B．only mice |
| C．only humans | D．neither humans nor mice |
| A．these mice had been given only 80 milligrams of caffeine |
| B．these mice hadn’t been injected with caffeine |
| C．these mice were very big and strong |
| D．these mice hadn’t been given enough caffeine |
| A．Human and Mice | B．New Radiation Defense—Coffee |
| C．Deadly Radiation—Gamma Radiation | D．Mice Died of Caffeine |

Teenagers who drink alcohol are at higher risk of becoming victims of violence, a Cardiff University study has found.
A team from the School of Dentistry' s Violence Research Group studied drinking habits in
children aged | 1-16 in England. They found not only a link between drink and violence but also
that children who drank were more likely to be hit, even if they weren' t violent themselves.
The researchers are now calling for measures to prevent alcohol misuse to reduce injury
risk. Current policy focuses on reducing aggression but this research shows that there should be
equal effort to reduce victimization(受害).
More than 4,000 children were surveyed at 13 schools at four local authorities in the North, the Midlands, London, and the South. The study found that 25% of 1 l-year-olds were drinking
monthly and 3.6% daily, with 12.8% admitting to getting drunk 3 to 5 times a year. By the age
of 16, 40% were drinking weekly and 6.2% were drinking every day. The research also showed
22.6% of 16-year-olds were getting drunk more than 21 times a year.
The study, which has just been published in the Journal of Adolescence, found a strong
link between frequency of drinking and frequency of hitting other people.
However, children who reported drinking monthly were also three times more likely to be
hit. Adolescents(青少年) who drank but didn't get into fights were more likely to be hit than
those who did fight.
Professor Jonathan Shepherd, who led the research, said a lot of previous alcohol-related
violence work had focused on the offenders rather than the victims. His team is calling for more pre-vention work from parents and teachers in the first two years of secondary school by taking advantage of the "teachable moment", that is, immediately after a student has missed school because of drunkenness.
Previous work by Professor Jonathan Shepherd has shown drinkers may be more at risk of vio-lence because of reduced physical co-ordinatlon ( 配合), poor decision-making in threatening situa-tions and isolation while out late at night.
He said,"This new study seems to be the first to show a direct link between alcohol misuses and victimization. There now needs to be much more effort put into reducing alcohol misuse in order to reduce injury. "
58. The underlined word "aggression" in the third paragraph probably means_____
A. violence B. sad feelings C. bad manners D. drunkenness
59. Drinkers may be more at risk of violence because of all the following EXCEPT __
A. reduced the physical co-ordination
B. isolation while out late at night
C. a higher frequency of hitting other people
D. poor decision-making in threatening situations
60. Which of the following statements is NOT true according to Professor Shepherd' s research?
A. The frequency of children getting drunk increases with age.
B. His previous alcohol-related violence work had focused on the offendersl
C. Some children missed school because of drunkenness.
D. This new study shows a direct link between alcohol misuse and victimization.
