It has been a dream for 30 years but now the world's first flying car is set to hit the roads this year.

    Ever since the “Back to the Future” movies lit up our screens in the 1980s，designers have dreamt of cars that could take to the sky at the push of a button．And now pilots can order their own “roadable” plane for just £ 127,000.

    The plane, which has fold-out wings that span(翼展)17.5ft，has a range of flying distance of 460 miles and can be up to 115 mph．Back on the land，it can also travel at“highway speeds”in car mode(模式)．

Fueling the 19ft. long plane couldn't be simpler—-you just drive it into a petrol station and fill it up．

    A spokeswoman said, “You can keep you ‘light-sport airplane' in your garage.But because it needs a short runway to take to the air, you will have to drive to your local airport，fly up to 460 miles, land，and drive directly to your destination．You will always be ready to drive or fly．"

    The spokeswoman added,“Never let bad weather change your trip.You call simply divert(改道)and continue on the ground until the weather clears.”   

    There is no risk to you—This is only the chance for you to be the first at your home field to unfold your wings and fly into the future．

    As any parent knows too well, sometimes a little white lie is the only way to make a naughty child quiet. Indeed, parents have shared the top white lies they've told their children. While some of them are amusing, others are somewhat cruel.

    “Father Christmas is watching you,” “Carrots will make you see in the dark” and “Your pet has gone to live on a farm” are among the top white lies parents tell their children. The top 20 list of little lies that adults use shows that four in five parents have told their children something that isn't true. The threat of Father Christmas is on the top, with 62 percent of parents employing St. Nick to keep their kids under control. The second on the list is: “We'll see”, which any little one knows really means “no”.

    The majority of British people say that they lie to their children to protect their innocence, to save them from being upset or to stop them behaving badly. The top white lie told to kids about their pets is “your pet has to live on a farm in the countryside”, which is employed after one dies or has gone missing. On average, parents think that children are ready to start learning about death at the age of seven and a half.

    One 62-year-old recalled that when he was four, his cat ran away, because it kept having its tail pulled. It was 53 years later that it was revealed that the cat had actually been given away to stop it from scratching the furniture. One respondent (应答者) said that he still remembered that when he was young, he believed his father's statement that the entire world used to be in black and white before colour photography came along.

    Forty percent of parents say that they would definitely lie to their children to keep up their belief in Father Christmas, and over all say they'd certainly tell the truth about a pet dying. However, one in ten parents say they've replaced their children's dead pet with a one looking the same to cheat their children into believing it was still alive and well, found the study by Blue Cross pet charity.

    In Scotland, 600,000 tonnes of food are thrown away every year. This amount of food, which could as feed about 1.2 billion poor people, is almost a third of household (家庭) waste. And food waste isn't just a big problem in Scotland.

    Money time, and resources (资源) are often wasted by throwing away good food. It also causes very harmful greenhouse gas, which is perilous to the planet.

    In the production stage, some foods do not enter the food chain for many reasons. Supermarkets usually care about the quality of food from farms. They often refuse strange-looking and unusually sized produce. However, they seem to forget that it is almost impossible to grow the perfect produce. Food waste at the consumption (消费) stage includes food going out of date and leftovers (剩饭) because of too much food. In households, even mostly fresh fruit and vegetables are thrown away.

    In order to reduce food waste, here is what we can do:

    Understanding the terms “use by” and “best before” dates. “Use by” dates are there for your safety. It is dangerous to eat food after the use-by date and doing so risks your health. “Best before” dates tell you how long the food will be at its best quality. Once the food passes the date, it isn't necessarily bad, but you should still check, just to be sure.

    Every time you go shopping and you bring back new food, put them at the back of your fridge and bring the food that will expire (到期) soon closer to the front. That way, you know what needs to be eaten first.

    If you have any food that will expire soon, give it to charity if you aren't going to eat it. They will really appreciate the food you have given.

    Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should know that your choice of sport might have great influence on the environment.

    Some sports are resource-hungry（消耗资源）. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses（球场）in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

    There are many environmentally-friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of shoes; and you don't have to worry about resources and your wallet. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

    Whatever sport you take up, you can make it greener by using environmentally-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms(健身房；体育馆)”. They are better replacements（代替物）for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or some other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

    The year was 1932. Amelia Earhart was flying alone from North America to England in a small single-engined aeroplane. At midnight, several hours after she had left Newfoundland, she ran into bad weather. To make things worse, her altimeter (高度表) failed and she didn't know how high she was flying. At night, and in a storm, a pilot is in great difficulty without an altimeter. At times, her plane nearly plunged (冲) into the sea.

    Just before dawn, there was further trouble. Amelia noticed flames coming from the engine. Would she be able to reach land? There was nothing to do except to keep going and to hope.

    In the end, Amelia Earhart did reach Ireland, and for the courage she had shown, she was warmly welcomed in England and Europe. When she returned to the United States, she was honored by President Hoover at a special dinner in the White House. From that time on, Amelia Earhart was famous.

    What was so important about her flight? Amelia Earhart was the first woman to fly the Atlantic Ocean alone, and she had set a record of fourteen hours and fifty—six minutes.

    In the years that followed, Amelia Earhart made several flights across the United States, and on each occasion (时刻) she set a new record for flying time. Amelia Earhart made these flights to show that women had a place in aviation (航空) and that air travel was useful.

    First-time shoppers at Seattle-based Amazon Go may feel as though they were stealing. That's because the 1,800 square-foot grocery store, which opened its doors to the public on January 22, has no cashiers or even checkout counters. Instead, as the name indicates, customers merely grab what they need and go! But before you start celebrating, the goods are not free—the cost of the purchase(s) is/are calculated electronically using “Just Walk Out” technology.

    The process is simple. Upon entering the store, shoppers “sign-in” by scanning their smartphones. Every item selected gets added to the bill automatically. If the customer changes his mind, all he has to do is return the purchase to the shelf, and it will be removed from the final bill. Though consumers will not find everything they need, they will be able to buy basics like bread, milk, and drinks. There are also numerous ready-to-eat breakfast, lunch, and dinner choices made by chefs in the on-site kitchen. Those that prefer to cook at home can select from the wide variety of Amazon Meal Packages.

    Once the customer exits the store, the system processes the purchases and charges the cost to their Amazon account. Within seconds, the customer is notified of the deal with a digital receipt that lists each item bought, as well as the time spent in the store. The accurate tracking is possible thanks to multiple smart cameras that monitor everything the shopper is doing. Kumar explains,“Cameras figure out which interactions(互动) you have with the shelves. Computer vision figures out which items are taken. Machine-learning also determines which item it is.” The company insists that the system is so accurate that shoplifting(偷盗) is impossible. And they should know, considering that Amazon employees have been shopping there since 2015!

    The store has raised some concern about the jobs of the over 3.5 million cashiers in America. However, Amazon officials say they have nothing to worry about because human employees are not being displaced. They are simply assigned other essential tasks, like preparing meals, restocking shelves, assisting customers, and solving technical issues.
