Texting is a great way to communicate and teenagers are doing just that. New research shows that on average, teens are sending 2,000 text messages a month, and doctors say it’s causing injuries.
13-year-old Bailey Baker keeps using her thumbs, sending text messages to her friends again and again. The past March may have been her best month ever, texting 8,000 times. Now, she says she’s feeling the pain. “Just mainly back and neck problems and thumb numbness,” she says.
Baylor-Garland Dr. Jane Sadler is seeing more and more teens who simply text until it hurts. She says parents, including Bailey’s mom, have no idea how much their kids are texting. “I was thinking she was texting about 25 texts a day,” says Lisa Baker. “Wrong! We’ve uncovered a problem.” It didn’t take Dr. Sadler long to find the problem. She gave Bailey the once-over and learnt that Bailey had developed Texting Teen Tendinitis(肌腱炎)
“A lot of them report pain in their thumbs, back and neck,” says Dr. Sadler. “When we look into it 
and examine a little bit further, we see texting is the main cause of the problem.” Dr. Sadler says back pain is caused by poor posture while texting. Bailey often texts for up to 2 hours a day; that’s a lot of wear and tear on the thumbs which over time, can break down. Dr. Sadler tells over-texting teens to look into the future. “What I tell them is ‘Hey, you might be normal now, but when you are 40 or 50, you can get arthritis (关节炎).’”
Dr. Sadler recommends limiting texting to 50 a day, and keeping good posture. Dr. Sadler also says touch screens are easier on the thumbs than keyboards and hand exercises are great to build up those muscles, making it easier to text.

Men have always believed that they are smarter than women. Now, a study has found that while this is certainly true, men also have to deal with the fact that they are also more stupid than the fairer sex.
In the study, scientists measured the IQ of 2500 brothers and sisters and they found an uneven number of men not only in the top two percent, but also in the bottom two percent.
The study's participants were tested on science, maths, English and mechanical abilities.
Though there were twice as many men as women in the smartest group, there were also twice as many men among the bottom.
The aggregate（总数）scores of men and women were similar.
One of the study's authors, psychology professor Timothy Bates, said that the phenomenon may be because men have always been expected to be high achievers and women have been restricted to spend more time taking care of their homes.
"The female developmental program may be tilted more towards ensuring survival and the safety of the middle ground.," the Daily Mail quoted Professor Bates, of Edinburgh University, as saying.
The research tallies with past results that men were more likely than women to receive first class University degrees or thirds and women secured the seconds.
It has been said that men are more ready to take risk when it comes to academics. Women have always found to be steadier in their learning.
A past study has shown that women are securing more firsts and seconds, while men are continuing to receive more thirds.
The argument for the change is that the increase of coursework at the cost of exams favors women's steady approach.The purpose of the passage is to tell us that ________.
| A．man are smarter then women |
| B．man are more stupid the women |
| C．a new fact about the IQ of men and women has been found |
| D．men are more likely to receive first class university degrees |
According to Timothy Bates, less women are in the smartest group because _________.
| A．they are born stupid |
| B．they have to spend more time to tale care of their homes than men |
| C．they don’t like to take risk |
| D．they are not expected to be high achievers |
The underlined word tallies with in the eighth paragraph means________.
| A．agree with | B．deal with | C．go against | D．go with |
It can be inferred from the passage that_________.
| A．Women are steadier in their learning. |
| B．men are more ready to take risk in everything |
| C．women are securing more firsts and seconds |
| D．women are doing much better in academy |
Which of the following questions has NOT been discussed in the passage? _________.
| A．Why are men smarter than women? |
| B．Why are men more stupid than women? |
| C．How does the result go along with the past research? |
| D．How can we help the men in the bottom? |
Not long ago the movie 2012 came into screen．The people were threatened by those scenes of destroying flood, severe earthquake, terrifying hurricane and constructions representing human civilization being destroyed and even swallowed by disaster．Luckily, they are just the director' s imagination, but the present situation is not heading a positive direction, either．
Take my own experience in Alaska as an example．Once I took a trip to the glacier．Along the way there stood signposts marking the snow lines of different years．They started from the foot of the mountain, but it was at the top that I finally saw melting glaciers（融化的冰川）．My heart ached seeing the beautiful blue ice melting at every second．
Sad but true, they are the effects of global warming and the result of our human impact．Furthermore, each year the rising sea level will kill 56 million people, and that' s about the population of the entire Italy．According to studies, if the temperature keeps on rising like this, by the year 2050, some islands and coastal cities including New York, Shanghai, Tokyo and Sydney will be drowned in water．
Our fortune is in our own hands．It depends on us to shape our future, to reduce future human impact and find ways to form a peaceful relationship with our environment. Therefore, it's time for actions to be taken right now．Contribute a little to energy saving by using more efficient light bulbs and less hot water．Let recycle become our habit by thinking twice before throwing something away．Let us take public transportation as our first choice when going to a certain place．It might cost more time for now, but it' s to the benefit of a permanent future．Take care of every tree and grass around us by watering them or simply just avoid destroying them．
In a word, small drops of water make a big ocean． The earth does not belong to us．On the contrary, we belong to the earth． Please bear in mind that the earth is our home．It is our responsibility to build a brighter and better future of our planet and prevent what happened in the movie 2012 from becoming reality． Why does the author talk about the movie 2012 in the passage ? __________.
| A．To give example． | B．To lead into the topic． |
| C．To make prediction． | D．To provide the evidence． |
How did the author feel when he took a trip to the glacier? ____________.

"Beating is a sign of affection, cursing (骂）is a sign of love."
Many may not expect to hear the words of the old Chinese saying in these modern times—with parents wealthier and better educated than they have ever been-but experts say they still ring true.
Today, it seems, Chinese parents are more likely to send their children to pre-college military academies in the United States in the hope that some tough love will pave the way tosuccess.
"Good education doesn't mean letting your child enjoy privileges, especially our boys," said Song Wenming, an entrepreneur(企业家）in Jinhua, East China's Zhejiang province." They should be raised in tough conditions to know what to fight for in the future."
In August, Song sent his 17-year-old son to Valley Forge Military Academy (VFMA) in Pennsylvania. And he is far from alone, even though it takes a lot of money - around $48,000 per year —to send a child to a strict military school.
Statistics shows that an increasing number of Chinese students have been registering with such academies.
A few years ago, there were no Chinese students at Valley Forge. Today, there are 28."All of the Chinese students at Valley Forge came from wealthy families, some of them were spoiled," said Jennifer Myers, director of marketing and communications at the school.
Song's only son, Song Siyu, had a rocky start during his first six weeks at the school. The teenager said he went to the school voluntarily but did not expect it to be as difficult.
Now, three months later, he has perfected the art of taking a bath in 35 seconds, finishing a meal without looking at his food, and making his bed with precision. He can even take criticism, no matter how unreasonable.
"The training is hard but I know it is good for self-development of individuals," said Song Siyu.'The endless training and scolding are just ways to build up our character, they are not personal."
But his enthusiasm is not universal. Ten of the 13 Chinese students who joined the academy this year have transferred to other schools.
But for those who stick with it, there is a reward for all the hard work.From the second paragraph, we can know the old Chinese saying _____.
| A．is out of date in modern times. |
| B．is disagreed by rich parents. |
| C．is still worth trusting |
| D．is deeply believed by better educated parent. |
The underlined sentence means that _____
| A．Song sent his only son to military school, so he feels lonely. |
| B．Song is the only one who sends his child t to military school. |
| C．There are other people sending their children to military school besides Song. |
| D．The fee of the military school is so high that only Song can afford it. |
Song Siyu got some achievements in the military school except _____.
| A．taking a bath in a short time |
| B．having his meal with his eyes closed |
| C．taking unreasonable criticism |
| D．improving his character |
How many Chinese students are there at Valley Forge before this year?
| A．10 | B．13 | C．15 | D．25 |
Which of the following can be inferred from the passage?
A. It's likely that more and more Chinese students will attend VFMA.
B. Most Chinese parents approve of educating their children by beating and cursing nowadays.
C. Song Siyu had no difficulty in adjusting to the life at VFMA.
D. Most Chinese students support the way of education at VFMA.
Seeing a volcano erupt is a wonderful experience, and you can really feel the beat by climbing to the summit(山顶) of Pacaya for a close-up view. There are guided tours every day up this highly active volcano from Antigua, giving travelers a chance to see Mother Nature at her most powerful.
Pacaya is an easy drive from Antigua, a beautiful city with many colorful houses along its old streets that are turned into art-works during its Holy Week festival. No matter when you come to Antigua, you won’t miss the Pacaya-tour companies.
But climbing Pacaya is no easy job: it is 2560 metres high, and reaching the summit takes two to three hours of seemingly one-step-forward and two-step-back movements. As you climb, you hear the dull sounds of eruptions high above steaming. Hot remains from recent eruptions begin to line the path as you are near the active summit; the McKenney Cone(火山锥).
Many tours are timed so when you arrive at the cone of the volcano there is plenty of time for sunset and the full contrast between the erupting red lava and the darkening sky. On a good day the view from the summit is extremely exciting. The active mouth boils, sending red lava over its sides, and once in a while shoots hot streams up to 100 metres into the air. There is a strong bad smell in the air even if you take care to be upwind of the cone. As evening turns deeper into the night, the burning lava quietly falls down the side of the volcano. For you, too, it is time to get down .What is the main purpose of this passage?
| A．To attract tourists to Pacaya. |
| B．To describe the beauty of Pacaya. |
| C．To introduce guided tours to Pacaya. |

It’s true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There’s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: “The global warming over the last half-century has been caused mainly by human activity.”
You may not believe that humans could change the planet’s climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible (看不见的) blanket.
Of course, the earth’s climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth’s going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.
Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren’t carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty. In most scientists’ opinion, the global warming is mainly caused by ________.
| A．solar activity | B．volcanic activity |
| C．natural factors | D．human factors |
The text is developed by ________.
| A．giving typical examples |
| B．following the order of space |
| C．analyzing a theory and arguing it |
| D．comparing and finding differences |
The underline word “identical” in the last paragraph probably means ________.
| A．totally different | B．exactly the same |
| C．extremely important | D．partly independent |
Which of the following is not the cause of climate change?
| A．volcanic eruption |
| B．cycles concerning the Earth’s going around the sun |
| C．changes in solar |
| D．floods and droughts |
Which of the following can be the best title?
| A．Are All the Scientists Really Scientific? |
| B．Where Is Global Warming Leading Us to? |
| C．Are Humans Definitely Causing Global Warming? |
| D．What’s the Relation of Global Warming and Greenhouse Gases? |
