Are you afraid of going to the dentist(牙医)?If so, you’re not alone.

These fears could just be in our heads, however. According to a recent survey by Martin Tickle, a professor at the University of Manchester in the UK, the pain isn’t felt most of the time in dental surgeries(牙科手术). In fact, among the 451 interviewed patients, 75%reported no pain at all during their visits, including situations when they had their teeth pulled out.

Could it be the sound of the drill(钻头)then?

“I found that the sound of drilling can evoke deep worry in dental patients. Actually they don’t have any pain, ”Hiroyuki Karibe, a scientist at Nippon Dental University in Tokyo, told The Guardian.

To find the reason why a drill might bring on a racing heart, Karibe divided the volunteers into low-fear and high-fear groups based on how much they feared a trip to the dentist. Volunteers were played the sound of a drill while their brain activities were watched by a machine.

What Karibe found in the low-fear group was increased activity in the areas of the brain relative to auditory processing(听觉处理), which means, for these people, the sound of dental drills is no different from other sounds.

In the high-fear group, however, the brain area that was activated(激活)was different. It was the area that carries out a number of duties, including learning, feelings and, most importantly, memory. This means that these volunteers not only heard the sound, but they remembered it——they made connections between the sound of a drill and the worry it produced in the past, causing their worry to return.

Understanding how brains reply to the sounds of dentists’ drills could help scientists find ways to make patients more relaxed, according to Karibe, because patients who worry about going to the dentist might keep putting off their visits. But the best way is to keep your teeth healthy.

文章大意:本文是一篇说明文。文章主要讲述了作者认为善良并不是能够被轻易教会的品质。

【推荐1】If you are a parent of young children who browses parenting websites, you will at some point be invited, through targeted advertising, to enrol your child in a Global Maths Skill Assessment — “to see how they compare to peers globally”. You may be urged to consider the possibility — no, probability — that they are “gifted” in some way, if not in maths, then in music or art. It’s window-dressing (门面粉饰) for subscription (订阅) services, but the other day, a line caught my eye that I haven’t been able to forget. “Talent isn’t everything; the important thing is to teach your child to be kind.”

This positioning of “kindness” as the opposite of “talent” is common once you start looking for it. Kindness is, everywhere: the consolation (安慰) prize, the award for perfect attendance. A few years ago, none of this would have struck me as noteworthy. I believed a tendency towards kindness wasn’t something we were born with, but instead something entirely reliant on cultivation. These days I wonder about that, and about our determination to see it that way.

It brings us to the problem of kindness; not only the fact that, in plenty of settings, it can be a code for weakness or neediness, but the fact that the word itself has been emptied out through misuse. Real kindness is not this. Kindness, I try to tell my children, is strength. My child who is always kind to others is frequently confused by the unfriendliness of others, at which point I have to bite my tongue. “Jessica was rude to you because she’s silly” is not what I’m going to teach my seven-year-old.

Can you teach someone to be kind? Of course, but also only sort of, not entirely. You can discipline them with reason and rewards in the same way you can send them to piano every week and eventually they’ll learn to play Twinkle Twinkle. The fact remains that some people are kinder than others not as a result of external forces but from some inborn ability. The ancient Greek storyteller Aesop said, “No act of kindness, no matter how small, is ever wasted.” Two thousand years later, it remains a hard sell.

1. Parenting websites often make use of various assessments of children’s talent to ________.
A.increase the click-through rateB.promote their targeted training
C.remind parents of their children’s talentD.have parents subscribe their services
2. In the second paragraph, the writer mentions “the consolation prize” to show ________.
A.kindness is viewed as the opposite of talent
B.consolation prize is a kind gesture that should be promoted
C.kind deeds are no easy to find
D.kindness deserves to be noticed in the contemporary society
3. What does the underlined phrase “bite my tongue” in Paragraph 3 mean?
A.Say nothing.B.Let out my anger.
C.Harm oneself accidentally.D.Explain something in pain.
4. According to the passage, which of the following statements does the writer most probably agree with?
A.Every child is talented, either in maths, music, art or kindness.
B.Kindness is your strength to talk back when offended.
C.Kindness is not something that can be easily taught.
D.Teaching can bring about children’s tendency towards kindness.

文章大意:这是一篇说明文。主要介绍了哥伦比亚大学的教授Michael Slepian关于保密的研究,他发现在告诉别人之前把好消息保密可以使人们感到更有活力。

【推荐2】If your partner gets down on one knee to propose, or you get a call with the job offer, your reaction might be to shout it from the rooftops. But new research suggests that keeping good news a secret before telling someone else could make people feel more energized.

“Decades of research on secrecy suggest it is bad for our well-being. However, this work has only examined keeping secrets that have negative effects for our lives. Is secrecy inherently bad for our well-being or do the negative effects of secrecy tend to originate from keeping negative secrets?” asked lead researcher of the latest research Michael Slepian, PhD, a professor of business at Columbia University.

In the experiment, some participants were asked to reflect on the good news they kept secret, while others reflected on good news that was not secret, and then rated how energized the news made them feel and whether they intended to share the news with someone else. The researchers found that the participants who reflected on their positive secrets reported feeling more energized than the participants who thought about their good news that was not secret.

The research nuances our understanding of the science of secrets. Negative secrets tend to deplete us and have also been linked to anxiety and depression. Positive secrets, however, seem to have an energizing effect and make people alive. One factor could be that people often have different motivations for keeping good news to themselves. Those with positive secrets were much more likely to keep quiet for internal reasons, not because they felt any outside pressures.

“People sometimes go to great lengths to plan revealing a positive secret to make it all the more exciting. This kind of surprise can be intensely enjoyable, but surprise is the most fleeting of our emotions, ” Slepian said. “Having extra time days, weeks or even longer-to imagine the joyful surprise on another person’s face allows us more time with this exciting moment, even if only in our own minds.”

1. What did Michael Slepian think of the previous research on secrecy?
A.One-sided.B.Pointless.C.Convincing.D.Pioneering.
2. In the experiment, some participants were more energized because ______.
A.they were optimistic and cheerful.
B.they were free from secrets.
C.they had undisclosed positive secrets.
D.they had shared good news with others.
3. What does the underlined word “deplete” in paragraph 4 mean?
A.Spoil.B.Exhaust.C.Confuse.D.Panic.
4. According to the last paragraph, what did Slepian suggest readers do?
A.Never reveal a secret casually.
B.Let your imagination run wild.
C.Be creative when surprising others.
D.Delay sharing a positive secret.

文章大意:这是一篇说明文,本文就喝剩下的水是否会变坏进行了研究。研究表明没喝完的水虽然味道有点怪,但只要水质是好的,保存恰当不被细菌污染,是不会变坏的。

【推荐3】We all know that water is tasteless. But it happens from time to time: you pick up the bottle of water you didn’t finish yesterday, and it tastes strange. Most often, you tend to drop the bottle in the trash bin, believing that the water has gone bad. But is it true?

According to Time, of course not, taste has little to do with quality of water.

According to Time, when water is exposed to the air for 12 hours, CO2 interacts with the H2O in the water, and the pH value lowers slightly. As a result, the water has a different taste.

“But it’s most likely safe to drink,” Norwegian expert Truls Krogh told Science Nordic. “If the water is covered and of good quality to start with, in principle it can last a thousand years. That’s because when water is fresh, it contains little organic matter. As long as water is held in clean glasses or bottles, no pollutants will enter it to harm our health.”

People in countries like the US, the UK and Australia usually drink tap water. According to Time, if tap water is drunk within six months, the chlorine(氯气)in the water will be enough to kill any bacteria and keep it safe to drink.

However, there are also some exceptions. If you accidentally put your fingers into water or store water in unclean containers day after day, microorganism (微生物) will enter the water.

With the help v of surrounding temperature, and sunlight streaming through windows, these microorganisms multiply quickly. Sooner or later, the water will be in the charge of the unfriendly bacteria. And if you drink the water too often, then you’re more likely to be ill.

And what about water in plastic bottles? Heat and plastic are a bad combination, US researcher Kellogg Schwab stresses. When plastic bottles are used at high temperatures, they produce a chemical called BPA.BPA is something that affects hormones (荷尔蒙) and research has tentatively linked it to “several health damage, including heart disease and cancer”, Time reported.

Schwab suggests replacing disposable (一次性的) plastic bottles with the refillable containers made of metal or glass to deal with BPA.

1. The purpose of the first paragraph is to ________.
A.show an exampleB.draw a conclusion
C.set a backgroundD.introduce a topic
2. What can we infer from the passage?
A.BPA does little harm to our health.
B.Tap water is always safe to drink.
C.Microorganisms are easy to produce in the heat.
D.Disposable plastic bottles have been forbidden already.
3. What can be the best title of the passage?
A.Why Is Water Tasteless?B.How to Get Clean Water
C.Does Water Really Go Bad?D.Learn to Protect Water
