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 network.
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 know 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 said 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 navigation 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 .

C.Asia, Europe and Oceania | D.the earth |
At the very beginning, the GPS system was built to help .

You may not pay much attention to your daily elevator ride. Many of us use a lift several times during the day without really thinking about it. But Lee Gray, PhD, of the University of North Carolina, US, has made it his business to examine this overlooked form of public transport. He is known as the “Elevator Guy”.
“The lift becomes this interesting social space where etiquette (礼仪) is sort of odd (奇怪的),” Gray told the BBC. “The elevators are socially very interesting but often very awkward places.”
We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, liftusers unthinkingly go through a set pattern of movements. He told the BBC what he had observed.
He explained that when you are the only one inside a lift, you can do whatever you want – it’s your own little box.
If there are two of you, you go into different corners, standing diagonally (对角线地) across from each other to create distance.
When a third person enters, you will unconsciously form a triangle. And when there is a fourth person it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle.
New entrants to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple – look down, or look at your phone.
Why are we so awkward in lifts?
“You don’t have enough space,” Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. “Usually when we meet other people we have about an arm’s length of distance between us. And that’s not possible in most elevators.”
In such a small, enclosed space it becomes very important to act in a way that cannot be understood as threatening or odd. “The easiest way to do this is to avoid eye contact,” she said.According to Gray, when people enter an elevator, they usually _____.
A.turn around and greet one another |
B.look around or examine their phone |
C.make eye contact with those in the elevator |
D.try to keep a distance from other people |

C.their unfamiliarity with one another |
D.their eye contact with one another |
What’s the passage mainly about _____.
A.Bad manners in the elevator |
B.Some unwritten rules of elevator etiquette |
C.An interesting but awkward elevator ride |
D.The strange behaviors in the elevator |
Should you spend your money on a home security system? A look inside a burglar’s mind might help you decide.
1. Of course I look familiar. I was here just last week cleaning your carpets, painting your shutters, or delivering your new refrigerator.
2. Hey, thanks for letting me use the bathroom when I was working in your yard last week. While I was in your home, I unlatched the back window to make my return a little easier.
3. To you, leaving that window open just a crack during the day is a way to let in a little fresh air. To me, it’s an invitation which I am more than happy to accept.
4. If it snows while you’re out of town, get a neighbor to create car and foot tracks into the house, or it will be a dead giveaway. By the way, loud dogs and nosy neighbors are the two things I hate most.
5. It’s raining. You’re fumbling with your umbrella, and you forget to lock your door---understandable. But understand this: I don’t take a day off because of bad weather.
6. Do you really think I won’t look in your sock drawer? I always check dresser drawers, the bedside table, and the medicine cabinet. Here’s a helpful hint: I almost never go into kids’ rooms.
7. You’re right: I won’t have enough time to break into that safe where you keep your valuables. But if it’s not fastened, I’ll take it with me.

Once Dr. Mellinkoff invited me to join him at the hospital to discuss interesting cases with his students. The case at hand was a Guatemalan man, aged 34, who had a fever and many other medical problems. His condition was not improving, and there was not much hope he would live.
Dr. Mellinkoff asked to see the patient. He introduced himself in Spanish and, in a very gentle voice, asked how he felt. The patient smiled and said everything was all right. Then the doctor asked if he was able to eat. The patient said that he had no desire to eat.
“Are you getting food you like?”
The patient said nothing.
“Do you get the kind of food you have at home?”
The answer was no.
The doctor put his hand on the man’s shoulder and his voice was very soft.
“If, you had food that you liked, would you eat it?”
“Yes, yes.” the patient said.
The change in the patient’s appearance couldn’t have been more obvious. Nothing was said, but it was easy to tell that a message had been sent and had also been received.
Later, the doctor asked why the Guatemalan man wasn’t getting food he could eat. One of the students said, “We all know how difficult it is to get the kitchen to make special meals.”
“Suppose,” the doctor replied, “you felt a certain medicine was absolutely necessary but that our hospital didn’t carry it, would you accept defeat or would you insist the hospital meet your request?”
“I would probably insist,” the student said.
“Very well,” the doctor said. “You might want to try the same method in the kitchen. It won’t be easy, but I can help you. Meanwhile, let’s get some food inside this man as fast as possible, and stay with it. Or he’ll be killed by hunger. By the way, there must be someone among you who can speak Spanish. If we want to make real progress, we need to be able to talk with him. ”
Three weeks later, Dr. Mellinkoff told me that the Guatemalan man had left the hospital under his own power. It takes more than medicine to help sick people; you also have to talk to them and make them comfortable.The patient had no desire to eat because __________.
A.he was not hungry |
B.he was seriously ill |
C.he was given special meals |
D.he was not satisfied with the food |
According to the passage, we can conclude that __________.
A.the patient was from another country. |

C.Dr. Mellinkoff performed an operation on the patient |
D.the hospital failed to provide the right medicine for the patient |
Which of the following words can be used to describe Dr. Mellinkoff ?

阅读下列短文,从每题所给的四个选项(A、B、C和D)中选出最佳选项。
Barack Obama,Lady Gaga and Steve Jobs-what do they have in common?They are,of course,all Americans. And according to a survey by social networking site badoo.com,they all best illustrate(举例说明)the word “cool”.
But just what does it mean to say someone is “cool”? Most would answer that it is something to do with being independent-minded and not following the crowd.
Yale University art professor Robert Farris Thompson says that the term “cool” goes back to 15th century West African philosophy(哲学).“Cool” relates to ideas of grace (优雅)under pressure.
“in Africa,”he writes,“coolness is a positive quality which combines calmness,silence,and life.”
The modern idea of “cool” developed largely in the US in the period after World War Ⅱ. “Postwar ‘cool' was in part an expression of warweariness...it went against the strict social rules of the time,”write sociologists Dick Pountain and David Robins in Cool Rules:Anatomy of an Attitude.
But it was the American actor James Dean who became the symbol for “cool” in the hugely successful 1955 movie Rebel Without a Cause. Dean plays a tough guy who disobeys his parents and the authorities. He always gets the girl,smokes cigarettes,wears a leather jacket and beats up bullies (欺凌弱小者).In the movie,Dean showed what “cool” would mean to American young people for the next 60 years.
Today the focus of “cool” has changed to athletics stars. Often in movies about schools,students gain popularity on the athletics field more than in the classroom. This can be seen quite clearly in movies like Varsity Blues and John Tucker Must Die.
But many teenagers also think being smart is cool. Chess and other thinking games have been becoming more popular in schools.

The website “FarmersOnly. com” calls itself an online dating and friendship finder. The idea started in the mind of a man,Jerry Miller in Ohio. He wondered how farmers could meet new people who understand the life of a farmer. Jerry Miller is not a farmer but he represents a lot of farmers.
As he tells it,the idea for the site was planted when a farmer told him one day that she was recently divorced and would like to date. But someone would invite her to meet for coffee at nine o'clock at night,when she had to start her day at five the next morning.
So,in 2005,Jerry Miller launched his website. “You don't have to be a farmer to be on ‘FarmersOnly. com’,but you do have to have the good old-fashioned traditional values of America's heartland.”
You also have to live in the United States or Canada to be a member of the site. Some services are free,but a full membership costs fifty dollars for a year. As of last week the site listed more than 58,000 members. Many of them are farmers in the United States. Others are students or workers involved in some way with agriculture. Jerry Miller tells us about thirty marriages in the last year have resulted from his website.
Some farmers have also found love through a group,Singles in Agriculture,which was formed as a nonprofit organization in 1986.It organizes gatherings that usually end with a dance,but is not a dating service. The purpose is to support educational and social activities that offer people a chance for friendship.
