Think about the last time you felt afraid. Was it a fear of height? Did you oversleep on a weekday and fear you’d get into trouble at the office? In any case, you know what it feels like to feel fear.

But one woman doesn’t the woman, code-named “UM”, gave her first-ever interview after years of being studied by a team of researchers. The woman is given a code name because the researchers want to protect her from anyone who would take advantage of her inability to feel afraid.

UM can’t tell you what fear is because she’s never experienced it. “I wonder what it’s like to actually be afraid of something,” she said. The formal name for the disease is Urbach-Wieth disease, which is characterized by a hoarse(粗啞的)voice，small bumps around the eyes, and calcium deposits(鈣沉積的)in the brain.

In the case of UM，the disease has transformed the part of her brain that controls the human response to fear. In the interview, UM talks about an event in her life where she was held at knifepoint and gunpoint, “I was walking to the store，and I saw a man on a park bench．He said. “Come here，please,” so I went over to him. He grabbed me by the shirt，put a knife to my throat and told me he was going to cut me. I told him, “Go ahead and cut me,” I wasn’t afraid at all. And for some reason，he let me go.”

Doctors who have been studying UM’s condition for years have been trying different things that could strike fear into her. They finally figured something out—increasing UM’s carbon dioxide levels．Extra carbon dioxide concentration in the blood is known to cause fear and panic in health individuals. Increasing UM’s carbon dioxide levels did manage to give her a fright．

A. To tell her case from other patients

Money is the root of all evil (邪惡) and new study claims there may be some truth behind the saying. Scientists at the University of California Berkeley, US, announced on February 27 that rich people are more likely to do immoral things, such as lie or cheat, than poorer people. The scientists did a series of eight experiments. They published their findings online in the Proceedings of the National Academy of Sciences (PNA《美國(guó)國(guó)家科學(xué)院院刊》).

They carried out the first two experiments from the sidewalk near Berkeley. They noted that drivers of newer and more expensive cars were more likely to cut off other cars and pedestrians at crosswalks. Nearly 45 percent of people driving expensive cars ignored a pedestrian compared with only 30 percent of people driving more modest cars.

In another experiment, a group of college students was asked if they would do immoral things in various everyday situations. Examples included taking printer paper from work and not telling a salesperson when he or she gave back more change. Students from higher-class families were more likely to act dishonestly.

According to the scientists, rich people often think money can get them out of trouble. This makes them less afraid to take risks. It also means they care less about other people's feelings.

Finally, it just makes them greedier. "Higher wealth status seems to make you want even more, and that increased want leads you to bend the rules or break the rules to serve your self-interest," said Paul Piff, lead scientist of the study.

Piff pointed out that the findings don't mean that all rich people are untrustworthy or all poor people honest. He said the experiments were to show how people living in different social situations express their instincts (本能) and values in different ways.

1.By saying "money is the root of all evil", the author wants to ________.

A. link wealth with bad behavior

B. draw readers' attention to the research

C. show how the saying proves the findings

D. defend rich people who do immoral things

2.According to the scientists, which is NOT the factor that makes rich people immoral?

A. They welcome risks.

B. They have more desires.

C. They believe money talks.

D. They become more selfish.

3.Why did the scientists do the experiments?

A. To show how social status affects people's morality.

B. To show people's instincts and values in different ways.

C. To test whether the saying "money is the root of all evil" is true.

D. To show the difference between higher-class people and lower-class people.

4.What does the passage really want to show us?

A. The poor are respectable.

B. Money is the root of all evil.

C. All rich people are untrustworthy.

D. The rich are more likely to act badly.

And visitors aren’t getting wet. Instead, visitors wander in awe, admiring the rain and the artists who created it.
