People should be warned against using mobile phones outdoors in stormy weather because they may “be struck by lightning”, according to doctors.
Three experts have described how a teenage girl was struck by lightning while using her phone in a large London park. The girl, aged 15, recovered, but a year later was still wheelchair-bound and found to be suffering complex physical and emotional problems.
The girl also had a perforate eardrum(打孔耳膜)on the side where she had been holding the mobile phone. She was having general recovery in Northwick Park Hospital, Middlesex.
Swinda Esprit, a senior house officer, said that while the brain and muscle damage was similar to that of many lightning victims—who can experience heart attacks on being struck— the ear problems were not.
She said that the damages were particularly relevant for people who might be involved in less serious lightning incidents, who might otherwise recover, but would never get their full hearing back if struck while on the phone.
“We were shocked by the damage, which is why we wanted to draw attention to it,” Dr Esprit said. “A year on and she still was suffering these difficult hearing.”
They added that three other cases had been reported in newspapers in China, South Korea, and Malaysia. In the Malaysian case, a sales executive was killed by lightning while talking on his phone during a thunderstorm near Kuala Lumpur.
“All these events resulted in death,” the doctors wrote. “This rare phenomenon is a public health issue, and education is necessary to stress the risk.”
The Australian Lightning Protection Standard recommends that metallic objects, including cordless or mobile phones, should not be carried outdoors during thunderstorms. However, “the United States National Weather Service says on its website that both are safe to use “because there is no direct path between you and the lightening”.
Paul Taylor, of “the Met Office”, said the ear injuries were a consequence of mobile phones being metal, and not related to radio waves.
Mr. Taylor said that mobile phones should be treated as another piece of metal, similar to carrying coins or wearing rings, and people need to be warned against the possible danger.
51. What do we know about the teenage girl?
A. She was struck by lightning at school.
B. She completely recovered from being struck.
C. She still suffered from mental problems.
D. She had to press her ear all day.
52. It can be inferred that damage done by lightening while using mobile phones ______.
A. is more serious than that when one is not using a mobile phone                         
B. can be healed quickly except for heart attacks
C. is less serious because the victims can usually recover                   
D. is mainly in the brain and muscle of the victims
53. Why did doctors stress the risk about using phones outside in lightening?
A. Because more people are faced with it.     B. Because some deaths have been caused.
C. Because lightning is harmful for the brain.   D. Because a teenage girl got killed.
54. We can infer from the last three paragraphs that ______.
A. both cordless and mobile phones are safe to use outside in lightning
B. there is no direct connection between lightning and ear injuries at all
C. opinions differ as to whether it is safe to use mobiles phones in lightning
D. ear injuries are the result of carrying coins or wearing rings in lightning
55. The purpose in writing this passage is ______.
A. to draw attention to the risk of using mobile phones in lightening
B. to focus on various damages done to lightning victims
C. to tell us the news that a teenage girl was struck by lightning
D. to stress the danger of making phone calls in lightning

“When I grow up, I want to be...”
Almost all of us have thought about, or been asked to think about, our future careers. Our answers may differ greatly. Even now your aspirations may have changed from when you were in primary school.
However, it seems career options aren’t only based on personal taste. In a survey carried out by Teens, doctors, lawyers, and bankers were some of most popular careers that people said they hoped to follow. This is in line with a similar survey carried out in the UK in May 2011 by job website monster. Co.uk, in which medicine was the top choice among UK teenagers aged between 13 and 17.
Medicine and law are two of the oldest and best known professions. Their prestige (威望) may come from the fact that doctors and lawyers are some of the most esteemed members of society, and they make good money. Joining these high-profile professions is often seen as a sign of upward social mobility.
It is equally unsurprising that banking is now one of the most common career choices. Youngsters worldwide think of banking and see the money rolling in. Wealth is increasingly becoming one of the most important indicators of a successful career. British young men list the UK tycoon Alan Sugar, Microsoft founder Bill Gates and Facebook chief Mark Zuckerberg as their top role models “for their wealth”. Just as Chinese teenagers see being a banker as a good and fun pathway to “wealth”.
However, not every child has the makings of doctor, lawyer, or banker. They are those who see fulfillment and happiness in other areas, and many teenagers dare to ink more individuality into their career options. As the Teens’ survey discovered, a variety of unconventional jobs---coffee shop owner, gourmet(美食家),waiter at a fast food restaurant---are among teenagers’ career choices. They can be equally interesting and rewarding jobs.
With every choice comes responsibility and challenge, and all career paths require specific education and training, you have to learn to balance optimism and confidence with being realistic about your particular talents and skills.
What is the passage mainly about?

A.Choosing a good job is very important.
B.Careers in teenagers’ mind.
C.Teenagers in the UK like doctors.
D.The choice of career needs challenge.

According to the article, all of the following are the benefits of being a doctor except_____.

A.respect from others B.upward social mobility
C.high pay D.the oldest profession

What do youngsters think is increasingly becoming one of the most important indicators of a successful career?

A.Prestige B.Fulfillment C.Happiness D.Wealth

What can we learn from the last paragraph?

A.According to your particular talents and skills, you can choose your favorite career.
B.Specific education and training can help get a good job.
C.Whatever career you choose, you should balance optimism and confidence with being realistic about your particular talents and skills.
D.Responsibility is the most important when you choose a good job.

It was a comfortable sunny Sunday. I was going to meet an old university friend I hadn't seen for years, and was really excited to hear all his news.
My train was running a little late, but that was no big problem - I could text him to say I would be delayed. He would understand. But… where was my mobile phone? I had that familiar sinking feeling. Yes, I'd forgotten it at home.
No mobile phone. I'm sure I'm not alone in feeling anxious, on edge and worried when I don't have my phone with me. In fact, I know I'm not alone: two-thirds of us experience ‘nomophobia’, the fear of being out of mobile phone contact. That's according to a study from 2012 which surveyed 1,000 people in the UK about their relationship with mobile phones.
It says we check our mobile phones 34 times a day, that women are more ‘nomophobic’ than men, and that 18-24 year-olds are the most likely to suffer fear of being without their mobiles: 77% of them say they are unable to be apart from their phones for more than a few minutes.
Do you have nomophobia ?
· You never turn your phone off
· You obsessively check for texts, missed calls and emails
· You always take your phone to the bathroom with you
· You never let the battery run out
It's funny to think that around 20 years ago the only people with mobile phones would be businessperson carrying their large, plastic ‘bricks’. Of course, these days, mobile phones are everywhere. A UN study from this year said mobile phone subscriptions would outnumber people across the world by the end of 2014.
And when there are more phones than people in the world, maybe it's time to ask who really is in charge? Are you in control of your phone, or does your phone control you?
So, what happened with my university friend? When I arrived a few minutes late he just laughed and said: "You haven't changed at all – still always late!" And we had a great afternoon catching up, full of jokes and stories, with no interruptions and no nagging(唠叨的) desire to check my phone.
Not having it with me felt strangely liberating. Maybe I'll leave it at home on purpose next time.

Cell phones: is there a cancer link?
Could your cell phone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cell phones can cause brain tumors. “It’s apparent now that there’s a real risk, ” said Carpenter.
But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病学) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cell phones, ” said Linet. “We don’t have the evidence that there’s much danger. ”
Studies so far suggest a weak connection between EMFs(电磁场) and illness— so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cell phone use and cancer risk.
From the passage we can learn that some people are worried because _______.

A.they have evidence that the use of cell phones can lead to cancer
B.they make a fuss over cell phone use
C.some experts have given a warning
D.cell phones are responsible for brain tumors

By saying “I don’t support warning labels for cell phones, ” Dr Martha Linet has the idea that _______.

A.the worrying is unnecessary
B.cancer-warning labels should be on cell phones
C.there is a link between cell phones and cancer
D.cell phones have nothing to do with cancer

For many centuries,countless scholars have asked the question:What is beauty? As designers update the latest fashions and artists create their masterpieces, what is considered beautiful changes at an alarming pace.
Fifty years ago,the full-figured Marilyn Monroe was a symbol of the American aesthetic(美学的)value;today,many Hollywood actresses different in appearance from Marilyn’s have taken her place. However,aesthetic values not only differ from generation to generation,but do so along cultural lines as well. Often, what is considered disgusting to one civilization is just the aesthetic appeal in another. Thus it is difficult to give an absolute definition(定义)of beauty.
As fundamental(基础的)physicists,my colleagues and I like to believe that we are involved in a search for a beauty that affects definition. The beauty that we search for is not what is set up through the work of people and subject to the tastes, but rather what has been laid down by nature Physics allows its students to look past outer appearances,into a deeper beauty. As a human being,I am attracted by the visual appeal of a wave crashing on the beach. As a physicist, however I am able to see the deeper beauty of the physical laws that govern such a phenomenon.
In truth,since Albert Einstein put forward the idea that there might be one main physical theory that governs the universe,aesthetics have become a driving force in modern physics. Einstein and other later physicists have discovered that:Nature, as its most fundamental level,is beautifully constructed. The extraordinary simplicity of the laws that govern the universe is really breathtaking . As Einstein said, it would seem more likely that we should find ourselves living in a“chaotic(无秩序曲)world,in no way graspable through thinking”. Yet we are now closer than ever to a full understanding of the universe’s beautiful clockwork. As new discoveries and technologies allow us to examine the physical world on deeper and deeper levels,we find that the beauty itself becomes much deeper.
The reference to“Marilyn Monroe”in Paragraph 2 mainly serves to___________.

A.provide an example of today’s beauty standards
B.show there is no fixed definition of aesthetics
C.compare traditions of the East to the West
D.discuss her abilities as an actress

When appreciating a wave crashing on the beach,a physicist sees the beauty of___________.

A.the visual attraction B.the powerful sounds
C.the physical laws behind D.the lovely creatures

Why are Albert Einstein’s words mentioned in Paragraph 3?

A.To detail the functions of physical laws.
B.To highlight the range of Einstein’s influence.
C.To show that Einstein doubted the beauty of physics.
D.To stress the very simplicity of the laws of the universe.

The passage is mainly to___________.

A.present a special way of seeing beauty
B.emphasize the influence of physics
C.discuss the awareness of cross-culture
D.argue the traditional ideas on value

What’s the greenest place in America? If you answered something like the warm sunlight of Santa Barbara, you’d be wrong. The greenest place in America has almost no sign of nature— the buildings outnumber the trees— and the air isn’t all that great. What it has is density(密度)and efficiency— the twin qualities that finally define green in the global warming time. Applying those standards,the greenest place in America is New York City— particularly,the overcrowded,overpriced island of Manhattan, which produces 30% less per-capita(人均)greenhouse gas than that of the nation.
It’s that density that makes Manhattan so green. Manhattan’s population density is 800 times the national average. Density comes with negatives,certainly— small living spaces,air pollution— but it also enables amazing efficiencies.Over 80% of Manhattanites travel to work by public transport, by bike or on foot— compared to an average of about 8% everywhere else in the country. Manhattan’s apartment buildings are far more energy-efficient than the houses in the suburbs.
What’s true of New York City is more or less true of other American urban areas, which explains why a growing part of the environmental movement now focuses on greening cities, hoping to attract more Americans back downtown. There’s an effort to make cities more sustainable(可持续的),by improving public transport,reducing air pollution and upgrading energy efficiency. But even more important, it is quite urgent to change decades of government policies that have been in favor of the suburbs,with disastrous consequences for energy,the environment and the climate.
That’s exactly the difficult point. For all the high efficiency and convenience and richness of living in a city,there are disadvantages too.New York,for example,has some of the highest childhood asthma(哮喘)rates in the U.S.
So it’s welcome news that New York has continued to push its P1aNYC scheme, a long-term program to make the city greener and more sustainable over the next decades. Recently it announced an update to the plan that includes phasing out heavy heating oils in New York City apartment buildings by 2030,to be replaced with cleaner natural gas.
Manhattan is considered as the greenest place in America because of its__________

A.buildings and trees B.density and efficiency
C.sunlight and nature D.transport and population

We can infer from the passage that___________.

A.New Yorkers have urged the city government to carry out green policies
B.the public transport and living space are quite satisfactory in New York
C.life in the countryside is more comfortable and energy efficient than that in cities
D.the significance of making cities greener is gained in promoting energy efficiency

The underlined word “it” in the last paragraph refers to___________.

A.New York city B.PlaNYC scheme
C.Manhattan D.Santa Barbara

The underlined part “phasing out” in the last paragraph probably means___________.

A.rapidly promoting dealing with
B.widely suggesting researching on
C.gradually stopping using
D.immediately forbidding producing

What would be the best title for the passage?

A.Manhattan the Greenest Place in America?
B.The Higher Density,the Greener City?
C.PlaNYC Scheme:New York City’s Future
D.Living in Cities Does Good to the Environment
