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(粗哑的)voice,small bumps around the eyes,and calcium deposits(钙沉积的)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 a11.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.

The iPhone, the iPad: each of Apple’s products sounds cool and has become a fad(一时的风尚). Apple has cleverly taken advantage of the power of the letter “i” –-- and many other brands are following it. The BBC’s iPlayer --- which allows Web users to watch TV programs on the Internet ---used the title in 2008. A lovely bear --- popular in the US and UK --- that plays music and video is called “iTeddy”. A slimmed-down version(简装本) of London’s Independent newspaper was started last week under the name “i”.

In general, single-letter prefixes(前缀) have been popular since the 1990s, when terms such as e-mail and e-commerce(电子商务) first came into use.

Most “i” products are targeted at (针对)young people and considering the major readers of Independent’s “i”, it’s no surprise that they’ve selected this fashionable name.

But it’s hard to see what’s so special about the letter “i”. Why not use “a”, “b”, or “c” instead? According to Tony Thorne, head of the Language Center at King’s College, London, “i” works because its meaning has become ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or interactive, Thorne told BBC Magazines. “Even when Apple created the iPod, it seems it didn’t have one clear definition(定义),” he says.

“However, thanks to Apple, the term is now connected with portability (轻便) .”adds Thorne.

Clearly the letter “i” also agrees with the idea that the Western World is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.

Along with “Google” and “blog”, readers of BBC Magazines voted “i” as one of the top 20 words that have come to define the last decade(十年).

But as history shows, people grow tired of fads. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was connected with all things advanced and modern. However, as we entered the new century, the fashion disappeared.

1. People use iPlayer to __________.

A. listen to music B. make a call

C. watch TV programs online D. read newspapers

2. The underlined word “ambiguous” means “__________”.

A. popular B. uncertain C. clear D. unique

3. Nowadays, the “i” term often reminds people of the products which are __________.

A. portable B. environmentally friendly

C. advanced D. recyclable

4. The writer suggests that __________.

A. “i” products are often of high quality

B. I Teddy is alive bear

C. the letter “b” replaces letter “i” to name the products

D. the popularity of “i” products may not last long

Caffeine not only gives us a daily jump start, but new research suggests it also can strengthen long-term memory.

According to the US Food and Drug Administration, nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. That' s equivalent to about one strong cup of coffee a day. Writing in " Nature Neuroscience" , Johns Hopkins University researchers say their findings show that caffeine strengthens certain memories for up to 24 hours after being taken in.

" We've always known that caffeine has cognitive-enhancing effects (促智效果) , but its particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans, " said senior author of the paper Michael Yassa. " We re- port for the first time a specific effect of caffeine on reducing forgetting over 24 hours. " Conducting a double-blind trial, the researchers worked with a test group of people who didn't regularly consume caffeinated products. Five minutes after studying a series of images, the test subjects were given either a placebo(无效对照剂) or a 200-milligram caffeine tablet.

To check the caffeine levels of their test subjects, the research team took saliva samples (唾液样品) from them before they took their tablets and again one, three and 24 hours afterwards.

Both groups of test participants ( those who took the placebo and those who took the caffeine tablet) were tested the following day to see if they could recognize the images they' d seen the previous day.

The test included showing the test subjects another series of images that included some new images , those that were shown the previous day, as well as other images that were similar, but not the same as those they had viewed earlier.

The researchers found that more members of the group who were given the caffeine tablets were able to correctly identify some of the new images as " similar" to previously viewed images rather than incorrectly identifying them as the same.

"We also know that caffeine is associated with health and longevity(长寿) and may have some protective effects from cognitive decline like Alzheimer' s disease (阿尔茨海默症). " said Yassa.

1.The purpose of the new research is ____________.

A.to examine caffeine ' s memory-strengthening effects in detail

B.to write the paper " Nature Neuroscience"

C.to prove caffeine has cognitive-enhancing effects

D.to survey how much caffeine people consume a day

2. During the research , the researchers did the following things EXCEPT ________.

A.giving the test subjects placebos or caffeine tablets

B.checking the caffeine levels of the test subjects

C.showing the test subjects series of images

D.encouraging the test subjects to drink more coffee

3. How did the test subjects show the caffeine ' s memory-strengthening effects?

A.By taking the caffeine tablets instead of placebos.

B.By recognizing images they ' d seen the previous day.

C.By identifying the new images as the same.

D.By telling the differences between new images.

4.What will the next part of the text possibly talk about?

A.Ways to achieve health and longevity.

B.The harmful effects of cognitive decline.

C.The treatment for Alzheimer' s disease.

D.The effects caffeine has on health.

Life is filled with challenges. As we get older, we come to realize that those challenges are the very things that shape us and make us who we are. It is the same with the challenges that come with friendship. When we are faced with a challenge, we usually have two choices. We can try to beat it off, or we can decide that the thing presenting the challenge isn't worth the trouble and call it quits. Although there are certainly times when calling it quits is the right thing to do, in most cases all that is needed is commitment and communication.

When we are committed to something, it means that no matter how painful or how uncomfortable something is, we will always choose to face it through instead of running away from it. Communication is making a space for discussion and talking about how you feel as opposed to just saying what the other person did wrong. If you can say to a friend, "I got my feelings hurt", rather than "You hurt my feelings", you are going to be able to solve the problem much faster.

In dealing with many challenges that friendship will bring to you, try to see them for what they are: small hurdles you need to jump or get through on your way through life. Nothing is so big that it is impossible to get over, and hurt only serves to make us stronger. It is all part of growing up, it happens to everyone, and some day you will look back on all of this and say, "Hard as it was, it made me who I am today. And that is a good thing."
