Unlike chemists and physicists, who usually do their experiments using machines, biologists and medical researchers have to use living things like rats. But there are three Nobel prize-winning scientists who actually chose to experiment on themselves – all in the name of science, reported The Telegraph.
1. Werner Forssmann (Nobel prize winner in 1956)
Forssmann was a German scientist. He studied how to put a pipe inside the heart to measure the pressure inside and decide whether a patient needs surgery.
Experiments had been done on horses before, so he wanted to try with human patients. But it was not permitted because the experiment was considered too dangerous.
Not giving up, Forssmann decided to experiment on himself. He anaesthetized (麻醉) his own arm and made a cut, putting the pipe 30 centimeters into his vein. He then climbed two floors to the X-ray room before pushing the pipe all the way into his heart.
2. Barry Marshall (Nobel prize winner in 2005)
Most doctors in the mid-20th century believed that gastritis was down to stress, spicy food or an unusually large amount of stomach acid. But in 1979 an Australian scientist named Robin Warren found that the disease might be related to a bacteria called Helicobacter pylori.
So he teamed up with his colleague, Barry Marshall, to continue the study. When their request to experiment on patients was denied, Marshall bravely drank some of the bacteria. Five days later, he lost his appetite and soon was vomiting each morning – he indeed had gastritis.
3. Ralph Steinman (Nobel prize winner in 2011)
This Canadian scientist discovered a new type of immune system cell called the dendritic cell. He believed that it had the ability to fight against cancer.
Steinman knew he couldn’t yet use his method to treat patients. So in 2007, when doctors told him that he had cancer and that it was unlikely for him to live longer than a year, he saw an opportunity.
With the help of his colleagues, he gave himself three different vaccines based on his research and a total of eight experimental therapies(疗法). Even though Steinman eventually died from his cancer, he lived four and a half years, much longer than doctors had said he would.
1.The main purpose of the passage is to ________.
A. present some dangerous experiments that Nobel prize winners did on themselves.
B. list difficulties that scientists went through in order to make important discoveries.
C. explain why some scientists chose to experiment on themselves.
D. introduce a few Nobel prize winners who did experiments on themselves.
2. Which of the following is TRUE according to the article?
A. Forssmann’s experiment ended in failure.
B. Forssmann had the pipe pushed all the way into his heart.
C. Barry Marshall succeeded by drinking some Helicobacter pylori.
D. Barry Marshall’s experiment on himself confirmed that most doctors’ belief about gastritis was correct.
3.The underlined word “gastritis” in Paragraph 5 probably means ______.
A. a kind of bacteria B. a kind of stomach disease
C. a new type of therapy D. a large amount of stomach acid
4.From the text, we can conclude that Ralph Steinman ______.
A. discovered a new type of cancer cell called the dendritic cell
B. tried different therapies containing the dendritic cell on himself
C. had his request to experiment on patients denied
D. believed that he was better than doctors at treating cancer
5.Where can we read such a passage?
A. In a newspaper. B. In a poster.
C. In a textbook. D. In a science book.

Vending machines (投币式自动售货机) are found in 16% of U.S.elementary schools, 52% of middle schools and 88% of high schools.About 22% of students in grades 1 through 12 buy food in vending machines each day—and those purchases added an average of 253 calories to their diets, according to a new study in the September issue of the Journal of School Health.
Just to be clear, those were not 253 calories' worth of tofu, yogurt or carrot.The most popular vending machine items included soft drinks, candy, chips, crackers, cookies, cakes and ice cream.On the plus side (好的方面), kids also bought low-fat milk, fruit juice and even fruit, the study found.
But the eventual effect on kids' diets was not good.Those who bought from vending machines ate an average of 156 grams of sugar per day, compared with 146 grams for those who abstained (节制).They also consumed less fiber, iron and vitamin B.
One silver lining: Vending machine customers ate 4% less sodium (钠) than other students--an average of 3,287 milligrams per day compared with 3,436 mg for those who didn't buy from vending machines.That's probably because the extra snacks made kids too full to eat as much at mealtimes, when dishes are especially Salty.In any event, kids should eat no more than 1,200 to 1,500 mg of sodium each day, according to the Mayo Clinic.Even for adults, the government recommends a daily limit of 2,300 mg.
Overall, vending machines in school appear to be a threat to children's health.The researchers calculated that all that snacking adds up to about14 extra pounds per child per school year.For some students this might be a serious contributor to weight issues.The study was based on data collected from 2,309 children nationwide for the third School Nutrition Dietary Assessment Study, which was
conducted by the U.S.Department of Agriculture's Food and Nutrition Service.
1.The students using vending machines take in less of all the following EXCEPT .
A.sugar B.fiber C.vitamin D.iron
2.The underlined words “One silver lining” mean “________”.
A.a discouraging condition at present
B.a bright side of a difficult situation
C.an urgent warning from health experts
D.an increasing concern from the public
3.Why do kids buying food from vending machines take less salt probably?
A.They prefer less salty food.
B.They have formed healthy eating habits.
C.They eat less food at mealtimes.
D.They take less junk food as snacks.
4.What's the purpose of the text?
A.To teach children a balanced diet.
B.To introduce the finding of a new study.
C.To remind parents of children's health.
D.To tell the history of vending machines.
