An astronomer is making a case for launching pop singer Justin Bieber into suborbital space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager -- he would come back down to Earth eventually, after all -- but rather to help jump-start the emerging suborbital spaceflight industry. It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. "If there's more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good." Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport. None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z. Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists -- but Shostak is thinking about ways to make it grow. A celebrity launch isn't Shostak's only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling with cameras both inside and out, to give the public dramatic views of every mission. Some observers view commercial suborbital spaceflight as a potentially... What can we learn about suborbital spaceflight? A) A trip will return to Earth before finishing a lap. B) The whole trip will leave passengers weightless. C) Each trip can take 500 passengers. D) The trip will be too expensive even for celebrities.

Wang Weiguo, an award-winning actor of the National Theatre Company of China, was wandering through Bejing's Panjiayuan Flea Market when he found a treasure, 20 exquisite   picture frames . He bought them all. Inside the frames was a woman's life story. There were pictures of her as a baby and a growing child and pictures with her parents. Wang Weiguo was sure someone had lost them. He contacted the police and media. He showed them to friends and to people living outside China. No one recognized the people in the photographs. That was 1999. Wang never gave up the search. In 2010 he told the story to a TV host, Zhang Zequn, who suggested he contact China Radio International. Within three months of the story's being posted on CRI, someone recognized Julie Ege in one of the photographs. The wonderful Norwegian actress and model was the mother of the child whose growing years the photos traced. The child was Joanna Syson. She moved to Beijing in the 1990s to study Chinese. In 1999 she returned to Norway for six months, entrusting   all her belongings, including the photographs, to a friend. When she returned, the friend was gone. So were her belongings. She was heartbroken. More than a decade passed. Then, thanks to the story posted on CRI and to a visitor to the website, the trail   finally led to Joanna Syson.

Last Saturday on the way to the mall, two children, a boy and a girl, came running towards me with bottles on their hands, asking if I wanted bottled water. It was a surprising gesture. I was wondering if they were doing fund-raising. I knelt and asked them where their parents were and how much a bottle of water cost. Then two adult women came up to me explaining what the children were doing. "We are teaching the children to give without anything in return. We are teaching people to accept without giving in return. " Two mothers had bought bottled water and placed a sticker on all bottles with five different quotes : 1. Smile at everyone. You'll never know when someone may need it. 2. If Plan A does not work, there are 25 more letters in the alphabets. 3. Have a thirst for life. Every day is filled with possibilities. 4. In your thirst for knowledge, be sure you don't drown in all the information. 5. Dig your well before you're thirsty. The bottle I have has quoted No.5. A sudden change of attitude opened up between me, the mothers and the children. We are no longer strangers to each other. We were having such a great time chatting and I ended up helping them give away the rest of the bottled water. One young lady was so thankful that she happily accepted the water and said it was the best thing that happened to her all day since she had a bad day at work. A man refused and walked away saying "no thanks". A couple kept on bowing to us in gratitude. When it was all done, the children and I were giving each other high-five. It was so much fun. I think I had more fun doing this than the mothers and the children. Different quotes were placed on the bottles to   _  . A) inspire others to think positively. B) show how rich and colorful our life is. C) encourage people to get more bottled water. D) explain why at times abandonment is necessary facing trouble.

"How far is the next village?" the American asks a man standing by the edge of the road. In some countries, because the man realizes that the traveler is tired and eager to reach his destination  , he will politely say "Just down the road." He thinks this is more encouraging, gentler, and therefore the wanted answer. So the American drives through the night, getting more and more angry, feeling "being tricked". He thinks the man on purpose lied to him, for obviously he must have known the distance quite well. Had conditions been reversed  , the American would have felt he was "cheating" the driver if he had said the next town was not too far, and if he would be sorry to the weary driver, he would say "You have a good way to go yet, it is at least fifteen miles." The driver might be disappointed, but he would know what to expect. Whether to be accurate or polite leads to many misunderstandings between people of different cultures. If you know the situation in advance, it is sometimes easier to recognize the problem. We can learn from this passage that Americans   _  . A) are polite to anybody B) like to be honest and accurate C) often lie to others D) have no sympathy to others
