A meteorite (陨石) flew fast across the sky and exploded over central Russia on Friday, raining fireballs over a vast area and causing a shock wave that smashed windows, damaged buildings and injured l,200 people.
People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt the shock wave.
According to Russian space agency Roscosmos, the fireball, travelling at a speed of 30km per second, had burnt very brightly across the horizon, leaving a long white trail that could be seen as far as 200km away. Car alarms went off, thousands of windows shattered and mobile phone networks were disrupted.
“I was driving to work, it was quite dark, but it suddenly became as bright as if it were day,” said Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains. “I felt like I was blinded by headlights.”
The meteorite, which weighed about 20 tons and may have been made of iron, entered Earth’s atmosphere and broke apart 30-50km above ground, according to Russia’s Academy of Sciences.
The energy released when it entered the Earth’s atmosphere was about several thousand tons, the academy said, the power of a small atomic weapon exploding.
No deaths were reported, but the Emergencies Ministry said 20,000 rescue and clean-up workers were sent to the region after President Vladimir Putin told Emergencies Minister Vladimir Puchkov to ease the disruption and help the victims.
The Interior Ministry said about l,200 people had been injured, at least 200 of them children, and most from broken pieces of glass.“While events this big are rare, an impact that could cause damage and death could happen every century or so. Unfortunately there is absolutely nothing we can do to stop impacts.”When did the meteorite incident happen?

Who is your role model? Normally the answer to this question would be anyone around you who you find truly inspiring. It could also be someone like J. K. Rowling or Martin Luther King. Jr. , who have proven to be strong and intelligent people.
However, in today’s world, stars are regarded as role models along with the heroes listed above, despite their intentions or actions. Teens attempt to imitate their actions for two major reasons. Firstly, to be fashionable and accepted by popular culture, and secondly because stars’ actions are so well documented by the media that it seems to grab our attention and turns it to following stars’ lives. Much of the reports about stars is shocking and exhibits bad morals or lifestyles that aren’t right for teenagers. In addition, almost everything stars do is described beyond truth to make a shocking story by taking it to the next level.
However, teens must take responsibility for their actions. We can’t always blame stars for influencing us. Only you have control over yourself and only you choose to do something. Our bodies and actions are in the hands of no one else.
Now, who ever said stars are role models? Whether they choose to be or not, stars set examples as soon as they step into the spotlight. With reporters following and recording every move they make, it is impossible not to be watched and then be imitated. These people influence teens whether or not they want to. Why should someone who doesn’t want to be setting an example set one? So，should we look up to them or to people who are true and good role models? It’s our responsibility as teens to know right from wrong, and it’s time for us to take responsibility for our actions. In doing so，we will lean toward those inspiring people that want to be setting an example, and follow in their steps to be like them.According to the first paragraph, _______ can usually be role models.

“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.What does the passage talk about ?
| A．The history of mobiles. |
| B．The story of meeting an old university friend. |
| C．The addiction of playing mobile phone. |
| D．The terrible feeling of being without their mobiles. |
The underlined phrase “on edge”in the third paragraph probably means_______.
| A．nervous | B．energetic | C．crazy | D．surprised |
Which word is used to describe old mobile phones according to the passage?
| A．digital phone | B．cell phone | C．bricks | D．smart phone |
What’s the author’s attitude towards the using mobiles?
| A．Worried | B．Favorable | C．Neutral | D．Critical |
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 |
Which of the following best describes the attitude of the author towards the debate?
| A．Optimistic. | B．Objective. |
| C．Opposite. | D．Casual. ] |
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 |
