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（療法）. 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.

Frederick M. Hess is the director of education policy studies at the American Enterprise Institute, which is a nonprofit organization that conducts research on many public issues. He says that a long summer vacation doesn’t make sense in today’s world.

Can American students afford to take a summer vacation? In a summer vacation, millions of kids spend valuable time sending messages, watching TV, playing video games and doing shopping in the mall. They will also be putting their academic futures at risk.

Summer vacation once made sense in the past when you didn’t need an education to get a good job. But now things have changed. For today’s students, academic skills are important to students’future success, but such skills are affected in the summertime. Many nations don’t give kids an American-style summer vacation. They offer no more than seven consecutive（連續(xù)的） weeks of vacation. Most American school districts offer up to thirteen weeks. To compete in the global marketplace, Americans must be prepared to go up against international competitors.

Summer vacation also causes challenges for today’s families. In the 1960s, more than 60% of families had a stay-at-home Mom. Now two-thirds of American children live in households where every adult works. For these families, summer vacation can be more burden than break. Someone must watch the kids.

But the biggest problem may be how summer vacation hurts academic achievement. Researchers have found that disadvantaged students lose significant ground in the summertime.

A longer school year does not have to be an invitation to hard boring work. Rather, it should allow time-pressed teachers to conduct richer and more imaginative lessons. Schools would have more time to devote to athletics, languages, music and the arts. Summer vacation can be a grand thing. But in the 21st century, it may also be outdated.
