In choosing a friend, one should be very careful. A good friend can help you study. You can have fun together and make each other happy. Sometimes you will meet fair­weather friends. They will be with you as long as you have money or luck，but when you are down, they will run away. How do I know when I have found a good friend? I look for certain qualities of character，especially understanding, honesty and reliability(信任)．

    Above all else, I look for understanding in a friend. A good friend tries to understand how another person is feeling. He is not quick to judge. Instead, he tries to learn from others. He puts himself in the other person's place, and he tries to think of ways to be helpful. He is also a good listener.

    At the same time, however, a good friend is honest. He does not look for faults in others. He notices their good points. In short, a friend will try to understand me and accept me.

    Another quality of a friend is reliability. I can always depend on a good friend. If he tells me he will meet me somewhere at a certain time, I can be sure that he will be there. If I need a favor，he will do his best to help me. If I am in trouble, he will not run away from me.

    There is a fourth quality that makes a friend special. A special friend is someone with whom we can have fun. We should enjoy our lives, and we would enjoy our friendship. That is why I especially like friends who are fun to be with. A good friend likes the same things I like. We share experience and learn from each other. A good friend has a good sense of humor too. He likes to laugh with me. That is how we share in the joy of being friends. And I know that he is looking for the same quality in me.

    When I meet someone who is reliable, honest, and understanding，I know I've found a friend!

    TOKYO—Lonely astronauts on the International Space Station (ISS) may soon be getting a robot friend from Japan.

    Japan's space agency is considering putting a talking humanoid(有人的特点的) robot on the ISS to watch the work while astronauts are asleep, monitor their health and stress levels and communicate to Earth through the micro­blogging site Twitter.

    Japan's space agency JAXA announced this week that it is looking at a plan to send a humanoid robot to the space station in 2013 that could communicate with the ground through Twitter—primarily feeding photos, rather than original ideas —and provide astronauts with “comfort and companionship”．

    Following up on US NASA's “Robonaut” R­2 program, which is set for launch on the Discovery shuttle next week, the Japanese robot would be part of a larger effort to create and refine robots that can be used by the elderly, JAXA said in a statement.

    Japan is one of the leading countries in robotics and has a rapidly aging society with one of the world's longest life expectancies.

    Improving robot communication capabilities could help elderly people on Earth by providing a nonintrusive(无干扰的) means of monitoring the robot owner's health and vital signs and sending information to emergency responders if there is an abnormality, JAXA said.

    “We are thinking in terms of a very human­like robot that would have facial expressions and be able to talk with the astronauts，” said JAXA's Satoshi Sano.

    The robot was being developed with the advertising and communications giant Dentsu Inc and a team at Tokyo University.

    The NASA project has a human­like head, hands and arms and uses the same tools as station crew members. The “Robonaut” called R­2 is intended to carry out maintenance tasks in the station's Destiny lab.

    NASA says it hopes that humanoid robots could one day stand in for astronauts during spacewalks or perform tasks too difficult or dangerous for humans.

    For now, the $2.5 million NASA robot is limited to activities within the lab.

    For car rental, call Avis on + 65 6737 1668.

    I want to talk about a soldier. I saw him yesterday as my husband and I were enjoying a wonderful lunch in the cave-like dining room of an old hotel.

    It is hard to imagine being comfortable in a room that probably seats a thousand, but the real magic of the place is its wonderful setting. Every comer is a wood and stone masterpiece, with high glass windows that look out to the huge cliffs of the valley.

    A man entered with his family and took a seat. He wasn't in uniform, but he walked with the dignity of a soldier, and a slight limp (瘸). My suspicion was confirmed when he removed his hat and placed it on the table where I could see it. Embroidered (绣) on the cap were the words: "Iwo Jima Survivor".

    As they were waiting for lunch, the others talking happily, this gentleman was stating out of the window. He was content to be left out of the conversation and allowed to take in the wonderful and impressive view of the waterfall.

    I watched him, and imagined how much horror he had seen in the war. What losses did he suffer, and how many friends did he lose? What he had witnessed should have given him a good reason to lose faith in the world. Yet this tired soldier was smiling at the sky, at the sun and the roaring of the waterfall. Somehow, after everything, the world was still beautiful to him.

    I walked over to him and said, "Excuse me, sir. I'm sorry to interrupt, but I saw your hat, and I just wanted to say thank you for serving."

    He looked up at me, surprised, and said proudly, "You're welcome, and thank you, too."

    I told him I would go home and tell my children about this experience that I'd met him.

 German artist HA Schult is an unusual artist who uses trash(废物) to make sculptures. "We are living in the time of garbage," says Schult. "I created a thousand sculptures of garbage. They are a mirror of ourselves." Here, Schult was talking about his 1,000 trash sculptures in the form of humans. He first exhibited them in 1996 in the western German state of North Rhine-Westphalia.

"They are social sculptures," he explains. "They are not only sculptures for the eyes. They are sculptures to spread the idea that we live in the time of garbage." So far, Schult's social sculptures have been on show in Paris, in Moscow's Red Square, on the Great Wall of China, and in the desert next to the Pyramids of Giza near Cairo.

 HA Schult's work is unforgettable. Although his work has had a big influence on the art world, Schult remains modest about his creations. "Artists have to learn every time. We are not important. All that counts is the time in which we are living."

 Trash art has been around for years. But it seems that only the popular artists are regarded as true artists when working with trash. Why can't common people be considered artists when they use the same things and change them into some form of personal art? Maybe it's because we all have our own preset ideas of what art is and isn't, or whom artists are or should be.

 You can be an artist like Schult if you try. Look at used metal cans. What might be done with them? Imagine them in any number of new uses, or imagine them simply as an art form. What about boxes or clothing? Boxes can usually serve as new storage containers and houses for pets. And clothing? Imagine taking old clothes and turning them into hats or hanging organisers.

I just returned from India. While driving home from the airport, I was amazed by how everything in American streets 1 those in Delhi, a city in northern India. "You can eat off the street here!" I said. My family looked at me 2 I had gotten off a spaceship rather than a plane.

During the two years I was away, my friends and family 3 sending texts to each other by phone. After I came back, my phone was no longer 4 as before, just lighting up with the "ding" sound of a text, and I felt very 5 . I chose to talk to my friends instead of texting them. I asked my friends for their 6 as I made an effort to7 with them and rebuild our friendships.

While I was on my 8 trips, most of my friends had moved on with their 9 . We felt disconnected from each other's experiences. Just as 10 would always be part of my life, I understood that raising a family would always be part of theirs. I told them sometimes I felt 11 because I had been away and wasn't there for their 12 events.

Expats（侨民）in Laos say that sometimes, if you stay abroad too long, you become a permanent 13 . never quite making it as a local, and never feeling 14 in your home country. I 15 . If you always travel with a heart beating for your beloved ones, no matter how long you have been abroad, you will find satisfaction at home.
