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.

    There are many international organizations which work to save and protect endangered species (物种) and natural environment. If you would like more information about any of the organizations listed below, you can write to the addresses given.

    Everyone is welcome to visit our city Los Angeles (LA). I am sure you can do many things in Los Angeles with your kids.

    Fun at the Beach

    Thanks to its almost perfect weather all through the year, a visit to the beach is one of the best things to do when in Los Angeles with your kids. While they enjoy themselves nearby, you can simply lie back and have a good rest in the sun.

    Trip to Disneyland

    A trip to the City of Angels with your little angels is incomplete (不完整的) without a visit to the Magic Kingdom. The joy they'll feel from being around all those Disney characters that they know and love will light up your day, too.

    Visit to the Museum

    If you want to turn your stay in LA into an educational one for your kids, you should visit the museum. Starting with the Natural History Museum of Los Angeles County to the California Science Center, or even the Kidspace Children's Museum in Pasadena, you have many choices. I'm sure a visit to all these places will make your kids smarter.

    Visit to the University Studios Hollywood

    Your kids could get to see interesting things from some of the most popular movies ever. From the theme park of Jurassic Park to Wisteria Lane from the TV play Desperate Housewives, the Universal Studios Hollywood is a place that we all find wonderful.

    One silly question I simply can't stand is "How do you feel? Usually the question is asked of a man in action — a man on the go, walking along the street, or busily working at his desk. So what do you expect him to say? He'll probably say, "Fine, I'm all right," but "you've put a bug in his ear" — maybe now he's not sure. If you're a good friend, you may have seen something in his face, or his walk, that he overlooked that morning. It starts him worrying a little. First thing you know, he looks in a mirror to see if everything is all right, while you go merrily on your way asking someone else, "How do you feel?" Every question has its time and place. It's perfectly acceptable, for instance, to ask "How do you feel?" if you're visiting a close friend in the hospital. But if the fellow is walking on both legs, hurrying to catch a train, or sitting at his desk working, it's no time to ask him that silly question. When George Bernard Shaw, the famous writer of plays, was in his eighties, someone asked him, "How do you feel?" Shaw put him in his place. "When you reach my age," Shaw said, "either you feel all right or you're dead."

    No trip to Chicago is complete without a visit to the Art Institute, which is the second largest art museum in the nation.

Clair Hughes initiated her quest for frugal methodologies to extricate herself from a £3,500 educational advance that had spiraled into a financial overhang. This economic strategist commenced an online odyssey in search of vouchers that would provide her with markdowns on her purchases. She divulged that the full value of an item seldom left her wallet, proclaiming, "Deductions are perpetually accessible; the key lies in meticulous organization. Initially, I anticipated an onerous endeavor, but I have now assimilated this lifestyle to the point where it has become second nature. I have effortlessly amassed savings exceeding £15,000."

In the year 2010, Ms. Hughes directed her attention towards fiscal conservation when she relocated to share a domicile with her significant other, Shane Byrne, an instructor within the telecommunications sector. Seeking counsel through digital means, she implemented a series of astute financial maneuvers, such as transferring her financial overdraft to an account that levied no interest. Subsequently, after a few years, she encountered an online collective of individuals devoted to the art of voucher accumulation and resolved to experiment with their practices.

She dedicated considerable time to navigating the digital expanse in pursuit of vouchers, meticulously printing each one to accompany her on her commercial forays. Over the passage of time, she has secured some remarkable bargains. On one occasion, a pair of luminaries valued at £140 were hers for the mere sum of £35.

Two years prior, Ms. Hughes expanded her repertoire of economic strategies by incorporating rebate applications that offer monetary restitution on a spectrum of items from alcoholic beverages to personal care products. Post each commercial venture, she uploads visual documentation of her financial transactions, which are subsequently scrutinized, and restitution is granted on certain acquisitions.

Among her other premier recommendations for financial prudence, Ms. Hughes advocates participation in remunerative online surveys, which have yielded her a substantial cache of vouchers. She remarked, "I have encountered accounts of individuals gathering forsaken receipts from shopping carts to seek overlooked discounts. The extent to which vouchers and rebate applications have been of service to me is astonishing. The community significantly enhances my financial endeavors. There is invariably an individual prepared to elucidate the operational intricacies."
