Texting walkers aren’t just an annoyance to other walkers, Australian researchers armed with movie special-effects technology have determined scientifically that they’re threats to themselves. Using motion-capture technology similar to that used for films, researchers concluded that texting while walking not only affects balance but also the ability to walk in straight line.

“Some people like checking emails while walking to work in the morning,” said the study co-author Hoorn,“but they may not know it has a serious effect on the safety of themselves.” Other facts have also proved this. A tourist walked off a pier(长堤)near Melbourne last month while texting,bringing a sudden and icy end to a penguin-watching visit. Another person who was too wrapped up in his phone to notice dangers walked straight into the fountain in front of a shopping mall.

The Australian study involved 27 volunteers, a third of whom admitted having knocked into objects while texting. They were asked to walk 8.5 meters three times-once without phones, once while reading text and once while writing text, when eight cameras recorded their actions.

They found the volunteers using the phone walked slower, and, more seriously, they locked their arms and elbows in like “robots”, which forced their heads to move more, throwing themselves off balance.“In a pedestrian environment, inability to maintain a straight path would be likely to increase potential for traffic accidents,”said Mr Hoorn. “The best thing to do is to step aside and stop, or keep off the phone.”

Authorities worldwide have taken note. Signs on Hong Kong’s subway system advise passengers in three languages to keep their eyes off their phones. Police and transport authorities have highlighted the danger in Singapore, where the Straits Times newspaper recently declared cell phone-distracted road crossing as “bad habit No.2” contributing to the rising number of road deaths. Some US states, including New York and Arkansas, are considering bans on what they’re calling phone jaywalking.

A.Annoyed.
B.Absorbed.

D.Absent-minded.
2. What can we learn from the Australian study?

【推荐1】When we say older people shrink,we don't mean they become tiny enough to fit in your pocket!We just mean that it's common for older people to become a little shorter over time.This kind of shrinking can't be stopped, although people can slow this process.But why does shrinking happen at all?

Because of gravity,cushions between the bones in the spine(脊骨)get compressed(压缩),which makes a person lose a little height and become shorter.

Another reason why some older people shrink is because of osteoporosis(骨质疏松).Osteoporosis occurs when bone is broken down and not enough new bone material is made.Over time,bone is said to be lost.Bones become smaller and weaker and can easily break if someone with osteoporosis is injured.

Older people—especially women,who generally have smaller and lighter bones to begin with—are more likely to develop osteoporosis.As years go by,a person with osteoporosis can get small breaks in bones that are called compression fractures.These breaks cause collapse of the spine and over time the person with osteoporosis can become hunched over(驼背).

Did you know that every day you shrink a little,too?You aren't as tall at the end of the day as you are at the beginning.That's because as the day goes on,water in the disks of the spine gets compressed due to gravity,making you just a tiny bit shorter.Don't worry,though.Once you get a good night's rest,your body recovers,and the next morning,you're standing tall again!

Smoking and drinking alcohol can make this problem worse.Want to do something right now to build strong bones?I believe what I say will help you.

1. What can we infer from the text?
A.For shrinking,people can do nothing about it.
B.If someone is injured,he will become shorter.
C.Women have smaller and lighter bones than men.
D.We aren't as tall at the end of the day as we are at the beginning.
2. What should we do if we don't want to shrink faster?
A.Reduce gravity.
B.Sleep as long as possible.
C.Be careful not to be hurt by others.
D.Keep away from smoking and drinking alcohol.
3. We can learn from the text about osteoporosis that______.
A.it makes people shorter
B.shorter people usually suffer it
C.women are more likely to develop it
D.once our bone is broken down,it will occur
4. What is the best title for the text?

【推荐2】There’s something satisfying about volunteering. Studies have shown that volunteering helps people who donate their time feel more socially connected, thus warding off loneliness and depression. But a growing body of evidence suggests that people who give their time to others might also be rewarded with better physical health, including lower blood pressure and a longer lifespan.

Evidence of volunteerism’s physical effects can be found in a recent study from Carnegie Mellon University, published this month in Psychology and Aging. Adults over age 50 who volunteered on a regular basis were less likely to develop high blood pressure than non-volunteers. High blood pressure is an important indicator of health because it contributes to heart disease, stroke, and premature death.

It’s impossible for this study to prove that volunteering was directly responsible for the lower blood pressure. People who volunteer may be more likely to do other things, like eating a healthy diet or exercise, which lower blood pressure. But the results are in line with other findings on the topic.

How might volunteering contribute to lower blood pressure?Performing volunteer work could increase physical activity among people who aren’t otherwise very active, says leading study author Rodlescia Sneed, a doctoral candidate in social and health psychology at Carnegie Mellon University. It may also reduce stress. “Many people find volunteer work helpful with respect to stress reduction, and we know that stress is very strongly linked to health out-comes,” she says.

A 2012 study in the journal Health Psychology found that participants who volunteered with some regularity lived longer, but only if their intentions were truly altruistic. In other words, they had to be volunteering to help others-not to make themselves feel better.

The Greek philosopher Aristotle once guessed that the essence of life is “To serve others and do good.” If recent research is any indication, serving others might also be the essence of good health.

1. Which can replace the underlined phrase “warding off” in paragraph 1?
A.getting rid of.B.keeping up with.
C.running out of.D.putting up with.
2. Why does the author mention the study from Carnegie Mellon University?
A.To prove the benefit of volunteering to health.
B.To find out volunteerism’s physical effects on heart.
C.To explain the connection between exercise and health.
D.To warn readers the danger of volunteering to blood pressure.
3. What can we learn from what Rodlescia Sneed said?
A.Volunteers are supposed to be more outgoing.
B.Volunteer work can make people lack sports.
C.Taking appropriate exercise can strengthen social connection.
D.Performing volunteer work contributes to reducing stress.
4. What’s the text mainly about?
A.Volunteering can lower blood pressure.
B.Volunteering is beneficial to mental health.
C.Volunteering may be good for body and mind.
D.Volunteering can avoid suffering from heart disease.

文章大意:这是一篇说明文。文章介绍了什么是怯场,以及怯场的原因。

【推荐3】Stage fright, also called performance anxiety, affects actors of all ages and experience levels, from rookie kindergarteners to Broadway stars. Take Bella Merlin. She’s a professor of acting and directing at the University of California, Riverside. She has also acted for many seasons in several US theaters.Yet, she says,“For seven years, I feared the one thing I loved: acting.”

Signs of stage fright include sweating, rapid breathing, tightness in the chest and “butterflies” in the stomach. Not everyone shows all these signs or experiences them with the same intensity (强度). Yet extreme fear can make some actors escape mid-performance and bring the curtains down on promising careers.

It seems reasonable to blame stage fright entirely on bad-tempered directors or complicated lines. But psychologists have found the physical signs actually reflect deep-rooted fears of one’s own making. Such fears are instances of predicting a negative future outcome without including any other positive alternatives.

What are these fears? One is that of making mistakes. A few actors are afraid any error will ruin their own or their group’s reputation. These may include mispronouncing a word.

For those who have been performing for a while, memories of negative experiences can be an added burden. You’re remembering last year’s school play and imagining your classmates laughing at your errors.This distracts your attention, raising the chance you’ll make another error.

There’s a different worry for actors who put a lot of themselves into their characters. They fear that by not accepting their onstage personalities, the audience is labeling them as “worthless” in real life, too.

Whatever the fear, stage fright activates (激活) a stress-response system in your body. The alarm activating this system comes from an almond-shaped area in the brain called the amygdala. After it sounds the alarm, your body floods with two chemicals: adrenaline and cortisol. They make your heartbeat faster and tighten your muscles, putting you into a fight-fight-freeze mode.

Since stage fright originates in the brain, you might expect the cure exists there, too. You’d be right.

1. Why is Bella Merlin mentioned in Paragraph 1?
A.To illustrate what is stage fright.
B.To show stage fright is quite common.
C.To introduce a famous Broadway star.
D.To explain her mixed feelings about acting.
2. What does the underlined phrase “bring the curtains down on” mean in Paragraph2?
A.Go ahead with.B.Look forward to.
C.Bring an end to.D.Make a difference to.
3. Which of the following is a reason for stage fright?
A.Worries about making any errors.
B.No previous performing experiences.
C.Lines too complicated to remember.
D.Lack of devotion to stage performance.
4. What will be talked about in the following paragraphs?
A.More causes of stage fright.B.Other instances of stage fright.
