In the past decade the popularity of rock climbing has greatly increased, and so has the number of injuries. It has been estimated that rock climbing is now enjoyed by more than 9 million people in the US each year. Study findings revealed a 65 percent increase in the number of patients that were treated in US emergency departments for rock climbing-related injuries between 1991and 2008.
The study, published in the online issue of the American Journal of Preventive medicine,found that about 40,000 patients were treated in US emergency departments for rock climbing-related injuries between 1991 and 2008. The most common types of rock climbing –related injuries were fracture(骨折) and sprains （扭伤）。The ankle was the most common body part to be injured (40%).Climers in the study ranged in age from 2 to 74, with an average age of 26. The study also found that women took up a quarter of the injuries.
Falls were the primary reason for injury with over three-quartes of the injuries occurring as the result of a fall. The severity of related injuries had a lot to do with the height of the fall. Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower.
“We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbing-related injury, explained the study author Lara McKenzie, PhD, director at the Center for Injury Research and Policy at Nationwide Hospital. “This trend, combined with the fact that rock climbers have a higher hospitalizaton rate than other sports and recreational injuries, demonstrates the need to increase injury prevention efforts for climbers.

China launched its fifth Beidou orbiter into space on Sunday morning, moving it one step closer to its goal of building a navigation(导航) and positioning satellite netw
ork.
The Beidou, or Compass, system is being built to rival the US-developed GPS, the European Union's Galileo and Russia's Global Navigation Satellite System. It can allow travelers, drivers and military officials to kn
ow their locations.
The fifth orbiter was launched on top of a Long March 3A carrier rocket at 5:30 am on Sunday from Xichang of Southwest China's Sichuan province.
It is the third Compass satellite launched this year, following launches on Jan 17 and June 2.
The short interval of less than two months since the last launch demonstrated that "the country is stepping into a busy period of launching the Compass satellites", an unnamed official in charge of the project s
aid last month.
The first two orbiters were launched in 2007 and 2009 respectively.
Sun Jiadong, the Beidou program's chief designer, said on June 21 in a TV interview that China would launch 13 to 15 Beidou navigation satellites into orbit by 2012 to form a network that provides regional service covering the neighboring areas.
And in about 10 years, the network would be expanded to include more than 30 satellites covering the globe, he said.
The system is a crucial part of the country's space infrastructure for providing nav
igation and positioning services in transportation, meteorology, pe
troleum prospecting, forest fire monitoring, disaster forecasting, telecommunications and public security.
In addition, a global positioning system is crucial to any country's national security and defense, said Ran Chengqi, an official in charge of the program, referring to the fact that the US initially built its GPS system for military purposes.
It is unimaginable for China to go without such a system, he said.
Earlier reports cited（引用） Song Xiaojun, a Beijing-based military expert, as saying that 90 percent of the world's current weapons systems need a global positioning system.This news report was probably released.
| A．in January, 2010 | B．in June, 2010 | C．in July, 2010 | D．in August, 2010 |
The Compass System is expected to finally coverin the future.
| A．China | B．China and its neigh boring areas |
| C．Asia, Europe and Oceania | D．the earth |
At the very beginning, the GPS system was built to help.
| A．military officers to judge their locations | B．travelers to know their locations |
| C．drivers to reach their destinations easily | D．hunters to find wild animals smoothly |
Most 23-year-olds have
not done enough in life to be worthy of having their own documentary（纪录片）
Most 23-year-olds aren't LeBron James.
The NBA superstar, who recently won gold at the Beijing Olympics, has just released More Than a Game. It is a documentary that follows his rise to stardom (明星地位) and how he and four childhood friends overcame long odds to win a national championship in high school.
Combining footage (镜头) taken during James' career at St. Vincent-St. Mary High School in Akron, Ohio, US, along with one-on-one interviews by writer/director Kris Belman, home videos, and personal family photogra
phs, the film is about much more than basketball. At its core (核心) is a story of friendship, loyalty and love.
"We set out with a goal as kids and we wanted to accomplish that someway, somehow by using basketball as a tool, not knowing that it was going to create other opportunities fo
r us," James said. "We didn't know it was going to create a brotherhood and trust. We grew from kids into young men."
While 
James is the star, his former teammates, Dru Joyce III, Sian Cotton, Willie McGee and Romeo Travis, play a major role in the film.
Their journey began together as 8-year-old boys, winds through years traveling all over America playing in basketball tournaments and finishes in their senior season at St. Vincent-St. Mary High School.
At the time, Belman was a college film student. He set out to film James and his friends' season as his final school project, a 10-minute documentary. But after gaining the trust of the players and coach Dru Joyce, Belman spent two months filming and eventually teamed with producer Harvey Mason Jr to the full-length feature.
James hopes the film will inspire youngsters (年轻人).
"We set out with a goal when we were eight and we accomplished it when we were 18," he said. "It's a great story and I wanted to get it out to kids that have a dream, that they should continue to go after it, believe in it and live it if they want to accomplish something."LeBron James achieved his goal set at 8 when.
| A．he won a gold medal at the Beijing Olympics |
| B．He won a national championship in high school |
| C．he became a collage student |
| D．he was interviewed by Kris Belman |
Which of the following is unlikely to be included in the description of James?
| A．Friendly. | B．Faithful. | C．Hardworking. | D．Self-centered. |
More Than a Game is.
| A．James’ favorite story about his childhood |
| B．a documentary filmed by James’ classmate |
| C．a film made by Belman |
| D．an article a bout James’ high school life |
We can learn from the passage that More Than a Game is.
| A．inspiring | B．dull | C．puzzling | D．imaginary |
A Good Teacher is a Strict Teacher
One of the most important parts in the healthy development of a
child is played by education. But the way in which education is
understood has changed completely, as we must not forget that
the severe and unfeeling way of bringing up a child in the past
was primarily based on cruel grounding（基础）and strict
rules that were supposed to create accomplished individuals, the typical gentlemen. Nowdays,
society is much more open-minded and it does not put a great value on being strict, although this
doesn’t mean that opinions regarding this subject do not differ.
On the one hand, there are also people who believe that there has got to be a bound between
teacher and student if any satisfying results are awaited. Luckily for us, more and more teachers are
understanding this fact and are doing their best to get over the strict rules and get in touch with us.
My opinion is that only by having a friendly attitude and accepting other opinions, especially
those of your pupils, you are truly able to do your job at high standards. However, this does not
mean that a teacher shouldn’t be a bit more rough when he feels that things are getting out of hand.
All in all, I must say that a good teacher is the teacher that has the ability to be kind and strict at the
same time, thus achieving to gain his students respect and interest.The aim of education in the past was to.
| A．create perfect persons | B．create open-minded persons |
| C．bring up a child | D．build a cruel grounding |
According to the passage, the narrow-minded people think.
| A．a pupil is always interested in what he is learning |
| B．a pupil himself will improve his studies |
| C．children should be made to study |
| D．children don’t like a rough hand |
The underlined word “job” in the last paragraph can be replaced by.
| A．controlling | B．teaching | C．learning | D．punishing |
The author thinks a good teacher should be.
| A．kind and strict | B．skilled and clever |
| C．rough and cruel | D．friendly and practical |
It can be inferred from the passage that.
| A．society is much more open-minded and being strict is out date |
| B．as long as the teachers are strict with students, the students will certainly get good marks |
| C．most people are in favor of strict teachers because they have strict grounding and strict rules |
| D．if we expect students to develop in a healthy way, the good relationship between teachers and students is important |
As dangerous as sharks may have seed to people after watching Jaws, which was released on June 20,1975, the recent disastrous decrease in their numbers show that people have proven far more dangerous to sharks.
This disastrous decline is due in large part to commercial fishing of sharks. “The market for
shark fins（鱼翅）in East Asia opened up thanks to changes in their economy, increasing their
ability to spend money on things such as shark fin soup,” Burgess said.
However, the biggest worry for sharks and their relatives, the skates and rays, which are suffering a similar fate, “is how they are killed incidentally when fishermen try and take other fish—the problem of bycatch（渔业混获）,” Burgess explained. “They may be thrown back afterward, but they’re still dead.”
The key of the problems behind bringing sharks back is that “they’re not the same as other fish,” Burgess said, “Sharks are slow growing and slow to reach maturity. Sharks are live bearers, which means females keep their young in their body just like us, but instead of nine months, it takes 12 to 18 months or more in sharks. Also, sharks generally can’t give birth again until a year after they’ve given birth—sometimes they’re on a three-year cycle. So once you get a shark population knocked down, this ‘life in the slow lane’ means that recovery is measured in decades rather than years.”\
Burgess said, “I’m on the recovery team for it, but the recovery plan for that is over the course of 100 years. So I won’t see them recover, nor will you, nor will your children. That’s what it means when these animals go down—they’re down a long time.”
Any measures aimed at saving sharks must not only consider byeatch, “which is the real killer right now,” but also encourage interactional cooperation, Burgess said.
“Sharks are very migratory, and many species cross borders,” he said. “We can protect them only by getting many govemment to come aboard. That’s the hardest part about this.”The text mainly tells us.
| A．shark fins are valuable | B．sharks are dangerous |
| C．bycatch brings bad effects | D．sharks are in danger |
The number of sharks is decreasing mostly because of.
| A．the film Jaws | B．commercial interests |
| C．changes in economy | D．shark fin soup |
Bringing sharks back is difficult because.
| A．they’re like the other fish |
| B．their reproductive rate is slow |
| C．they can’t give birth again |
| D．their life cycle is only 3 years |
What can be concluded from the last paragraph?
| A．Sharks live the way human beings do. |
| B．It’s time many govemments cooperate. |
| C．Sharks’ migration takes a very long time. |
| D．Bycatch shouldn’t be forbidden by intemational laws. |
The test is most probably a .
| A．newspaper ad | B．book review |
| C．science news report | D．science fiction story |
