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 .

TIJUANA, Mexico – A powerful earthquake swayed (摇动) buildings from Los Angeles to Tijuana, killing two people in Mexico, blac
king out cities and forcing the evacuation (疏散) of hospitals and nursing homes. One California city closed off its downtown due to unstable buildings.
The 7.2-magnitude quake centered just south of the US border near Mexicali was one of the strongest earthquakes to hit region in decades.
"It sounds like it's felt by at least 20 million people," USGS seismologist Lucy Jones said. "Most of Southern California felt this earthquake."
Sunday afternoon's earthquake hit hardest in Mexicali, a commerce center along Mexico's border with California, where authorities said the quake was followed by at least 20 smaller aftershocks, including ones of magnitudes 5.1, 4.5 and 4.3.
"It has not stopped trembling in Mexicali," said Baja California state Civil Protection Director Alfredo Escobedo on Monday.
Escobedo said one man was killed when his home collapsed just outside of Mexicali and another died when he rushed into the street in panic and was struck by a car. At least 100 people were injured in the city, most of them struck by falling objects. Power was out in virtually the entire city.
Susan Warmbier was putting away groceries in the San Diego suburb of Chula Vista when her husband asked, "Is the house moving?"
Elsewhere in San Diego, there were reports of shattered windows, broken pipes and water main breaks in private buildings, but no reports of injuries, San Diego Fire-Rescue Department spokesman Maurice Luque said. Coronado Bridge over San Diego Bay was briefly closed as a precaution.
Across the border in Tijuana, Mexico, the quake caused buildings to sway and knocked out power in some areas. No tsunami warning was issued, but hundreds of people on Tijuana's crowded beach feared the worst and fled when they felt the ground shake. What's the best title of the passage?

There’s talk today about how as a society we’ve become separated by colors, income, city vs suburb, red state vs blue．But we also divide ourselves with unseen dotted lines．I’m talking about the property lines that isolate us from the people we are physically closest to: our neighbors．
It was a disaster on my street, in a middle-class suburb of Rochester Town, several years ago that got me thinking about this．One night, a neighbor shot and killed his wife and then himself; their two middle-school children ran screaming into the night．Though the couple had lived on our street for seven years, my wife and I hardly knew them．We’d see them jogging together．Sometimes our children would share cars to school with theirs．
Some of the neighbors attended the funeral（葬礼）and called on relatives．Someone laid a single bunch of yellow flowers at the family’s front door, but nothing else was done to mark the loss．Within weeks, the children had moved with their grandparents to another part of the town．The only indication that anything had changed was the “For Sale” sign in front of their house．
A family had disappeared, yet the impact on our neighborhood was slight．How could that be? Did I live in a community or just in a house on a street surrounded by people whose lives were entirely separate? Few of my neighbors, I later learned, knew others on the street more than casually; many didn’t know even the names of those a few doors down．
Why is it that in an age of low long-distance expenses, discount airlines and the Internet, when we can create community anywhere, we often don’t know the people who live next door? Maybe my neighbors didn’t mind living this way, but I did．I wanted to get to know the people whose houses I passed each day – not just what they do for a living and how many children they have, but the depth of their experience and what kind of people they are．
What would it take, I wondered, to break through the barriers between us? I thought about childhood sleepovers（在外过夜）, and the familiar feeling and deep understanding I used to get from waking up inside a friend’s home．Would my neighbors let me sleep over and write about their lives from inside their own houses?

Cellphone users in the United States have contributed more than $11 million to Haitian earthquake relief through text messages in what is being called as an unexpected mobile response to a natural disaster．
The Mobile Giving Foundation called it a “mobile-giving record” for funds raised for a single cause．Donations are rising swiftly, as former President Bill Clinton and other politicians urge the American people to give．
Jim Manis, chief officer of the organization helping to manage cellphone donations, said it was receiving up to 10,000 text messages per second．The foundation said more than $11 million has been donated．
Cellphone users can donate $5 to Haiti-born hip-hop musician Wyclef Jean’s Yele Haiti Earthquake Fund by texting the word “Yele” to 501501, or they can donate $10 to other nonprofit organizations, such as the American Red Cross, by texting the word “Haiti” to a specified number, like 90999．
The donation is charged to a user’s cellphone bill．
The American Red Cross said it has received more than $ 9 million in donations from more than 900,000 mobile phone users．
“It’s beyond our imagination that we’ve received this amount,” said spokeswoman Nadia Pontif．
Jean’s fund had raised $2 million via text messages, according to Give on the Go, Yele’s mobile application service provider．
The giving is also being fueled by the popularity of websites like Facebook and Twitter, where users are urging one another to make donations using cellphones．
Wireless carriers(无线运营商) Verizon Wireless, AT&T Inc．, Sprint and T-Mobile USA, a unit of Deutsche Telekom AG, have waived(免收) fees for customers wishing to send mobile donations．Carriers are also letting users know they are not taking a cut of the donations．
“There are no text messaging fees and 100% of the $10 donation goes to the American Red Cross, and every carrier is working through a solution to push those funds out faster．” Verizon said in a statement．

Two new studies suggest that modern running shoes could increase the risk of injuries to runners．
One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week．The runners were observed on a treadmill machine．Sometimes they wore running shoes．Other times they ran barefoot．
Researchers from the JKM Technologies Company in Virginia, the University of Virginia and the University of Colorado did the study．
They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot．They observed that the effect was even greater than the effect reported earlier for walking in high heels．
The study appeared in the official scientific journal of the American Academy of Physical Medicine．
The other study appeared in the journal Nature．It compared runners in the United States and Kenya．The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland．
They divided the runners into three groups．One group had always run shoeless．Another group had always run with shoes．And the third group had changed to shoeless running．
Runners who wear shoes usually come down heel first．That puts great force on the back of the foot．But the study found that barefoot runners generally land on the front or middle of their foot．That way they ease into their landing and avoid striking their heel．
Harvard’s Daniel Lieberman led the study．He says the way most running shoes are designed may explain why those who wear them land on their heels．The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first．Also, the heel generally has thick material under it to soften landings．
60．How many organizations are involved in the two studies?
A．Three． B．Four． C．Five． D．Six．
61．What can we learn from the text?
A．Most running shoes are designed improperly．
B．The design of high heels is better than that of running shoes．
C．No one will run with running shoes in the future．
D．Both of the studies are done in America．
62．Why do running shoes increase the risk of injuries to runners?
A．They could create stress．
B．They’re too big and heavy．
C．They can affect the way the runners land．
D．Their heels can soften landings．
63．How did the researchers do the two studies?
A．By practising． B．By comparing．
C．By questioning． D．By reasoning．
