BEIJING — The launch of a new manned space mission brings China closer to the establishment of a permanent space station, international experts say.

    Chinese taikonauts, Jing Haipeng, 50, and Chen Dong, 37, were blasted off into space onboard Shenzhou-11 at 7:30 am Monday and will spend 30 days in the Chinese space laboratory Tiangong-2.The launch marks a key step toward China's plan to eventually operate a permanent space station. The successful launch of the Shenzhou-11 spacecraft is another step forward to put China among leading players in space technology, said Alexander Zheleznyakov, a Russian expert on history of space flights. China's experimental space lab will help provide solutions for spacecraft of different functions to approach and anchor, and for a long-term operation of life support system, said Zheleznyakov. Shenzhou-11 is scheduled to anchor on Wednesday with Tiangong-2, which is part of China's plan to build a permanent space station by 2022.

    China can now test technologies for cargo spacecraft anchoring, life support system operation and water recycling to ensure a long-term continuous operation of its space station in the future with less dependence on renewal from the Earth, he said. If all goes well, China will launch the unpiloted Tianzhou-1 cargo ship next spring to autonomously tie up with Tiangong-2. Tianzhou-1 will be capable of automatically transferring rocket fuels, a vital requirement for space station grouping and maintenance, according to a report by Columbia Broadcasting System (CBS).

    "That will further their anchoring abilities needed for the larger space station," Johnson Freese was quoted." Tiangong-2 is supposed to be able to stay in orbit for two years or longer, so that's taking them (Chinese) really close to 2019 or so. I think this will be their last big technology test phase before going to their large space station," said Freese.

    Lots of people buy books and products from Amazon, an online seller. They offer and pay over the Internet and the books are shipped through the mail or a delivery service like FedEx.

    One day, people could get their Amazon deliveries from an “unmanned aerial vehicle”—a timely vehicle that looks like a toy helicopter. And instead of waiting days to get the parcel, it could be at the buyer's home in half an hour or less. The company is working on a fleet of tiny vehicles they call “Prime Air”. The vehicles are also known as “octocopters”. On their website, Amazon says, “One day, Prime Air Vehicles will be as normal as seeing a mail trucks on the road today.”

    The U.S.'s Federal Aviation Administration (FAA) is working on safety regulations for unmanned flying vehicles like the Prime Air copters. Those regulations will make sure the copters are able to fly safely where they need to go. Once the FAA has put its rules in place, which could be as early as 2016, Amazon will be ready with its fleet of tiny flyers. The process could take as many as five years.

    The new delivery service would likely be available only in the United States, at first. The copters the company is testing now can handle packages up to five pounds (2.3kg) and they have a range of 10 miles (16 kilometers).

    Other companies are also looking at using unmanned flying vehicles to deliver their products. For instance, Domino's Pizza in the U.K. released a video showing a “DomiCopter”, delivering a pizza. That video may have been a publicity stunt（噱头）. In any case, just like Prime Air's octocopters, the DomiCopters don't have clearance（许可）to take off just yet.

    One warm summer morning, Elizabeth, the nanny（保姆）of the William's, went back from outside with the little boy, Josh. When she stepped into the house from the front door, she could tell that something was wrong, but she couldn't point a finger at exactly what it was. Just as she was about to dash out to find Josh, the little boy ran from behind her back, straight into the house for his toys.

    That's when she heard footsteps coming down the stairs. Her heart missed a beat. Knowing that Josh's parents were not home, she ran inside the house, caught the little boy swiftly and headed straight for the gate. She hit the neighbor's door heavily to seek help and called the police.

    When David William returned home and checked the monitor, what he saw scared the life out of him. A strongly built middle-aged stranger walked around the house and searched every corner, being careful not to miss any valuables（贵重物品）. And the most frightening for David was to see him even slipping into Josh's room. It was also terrifying to see that he was on his phone with someone guiding him on what to do. When Elizabeth opened the front door, he realized it was time to leave. He ran out just a few moments after Elizabeth and the boy left, getting away from the police.

    The Williams feel so grateful to Elizabeth for what she has done daily and saving their little boy when she could have easily run leaving the child behind. Elizabeth is called “supemanny” by the family. But Elizabeth said it was just her normal duty. “When his parents are away, they put their trust in me to keep him safe.” Although she is still terrified at the thought of what could have happened if she had come face to face with that man, she is willing to continue doing her work.

    Thanksgiving is an important festival in North America. We interviewed several students from the US and Canada. Here is what they have told us about their Thanksgiving experiences.

    Josie from New York, USA

    “In America, Thanksgiving is celebrated every year at the end of November. It is to remember the first group of people from Europe to live in America. When they first arrived, they found the environment strange. But they learned to survive after some native American friends showed them how to grow and find food. Thanksgiving is meant to be a traditional celebration.”

Todd from California, USA

    “Thanksgiving is the first day of Christmas shopping. That means we have four weeks to buy Christmas presents for our families and friends. For me and my friends, the most important part of the festival is the big football game on TV. The match is watched by millions of people all over America. Thanksgiving is seen as an exciting day for football!”

    Ian from Saskatoon, Canada

    “In Canada, Thanksgiving is held on the second Monday in October. On the Sunday before Thanksgiving Day, many people go to church. Thanks is given for all the good things that happened to them during the year. I always give thanks for the nice big turkey I'm going to have at the family dinner! Like all festivals, Thanksgiving is about food!”

    Katie from Maritimes, Canada

    “On Thanksgiving Day, we have dinner with all our cousins, aunts and uncles. It is always very busy. Sometimes we have two Thanksgiving dinners because we go to both our grandparents' houses. The dinner is usually attended by more than twenty people at each house! My mother and my aunts do all the cooking but the washing-up is done by me and my cousins. And that's not an easy job! But I don't mind because Thanksgiving is meant to be a time to give thanks.”

    What do you do for fun in your spare time? Do you like reading? Do you often go to a book store? There is a store that is so different from others.

    The World's Smallest Bookstore, whose official name is just these three words, sits quietly about 100 miles northeast of Toronto.

    The bookstore is about 10 feet by 10 feet, so it is easy to imagine how tiny it really is. The bookstore is open 24 hours a day. Inside the bookstore are various books, especially literary books and classic authors' works. So if you are looking for something less popular, you may get a bit disappointed there.

    Another special feature of this bookstore is that each book only costs three dollars. All the expenses are paid on the honor system, which means buyers should make a note of what they've bought and leave their money by themselves. So the tools of the trade in this bookstore are quite simple: pens, papers, light bulbs and a label-maker.

    In order to catch passers-by's attention, the billboards (广告牌) of the bookstore are several times bigger than the store itself. With these large eye-catchers, many people are willing to stop by and have a visit.
