Is it a bird? Is it a plane? No, it's your online shopping! Imagine a world where your shopping was dropped off on your doorstep by a delivery (投递) drone (无人机). Well, many companies are working to make this idea a reality. Among them, Amazon and UPS are just some of the front runners in the race to have the first ever business drone delivery service.
Pros:
①Fast. Delivery drones can cut down the time of delivery to just 30 minutes.
②Environmentally friendly. Companies like UPS have started that the use of drones would cut down on waste gas (气体).
③Cheap. Though exact prices for drone delivery aren't known, companies such as Amazon suggest deliveries could be as cheap as $1.
④Emergencies. Drones can fly straight to areas they're needed without using any roads.
From Dispatch (分派) to Doorstep:
Usually products available for drone delivery will be stored somewhere nearby. Customers will choose these products through shopping apps or websites. The suggested weight to be carried is no more than 2.3 kilograms. Once the products are put into the drone, it will take off from the dispatch center. It will fly below 120m and avoid any "No Fly Zones" like airports for safety reasons. Before landing, a pad will be placed in the customer's garden for the drone's landing. After the drone puts down its product, it will rise to return to the dispatch center. So a drone delivery could one day be just a touch of an app with your finger.
Cons:
①Weather like strong winds, lightning storms and heavy rainfall may influence deliveries.
②Dispatch centers will have to be built within certain distance.
③Drones might be unable to land safely in high-rise buildings.
④Something will have to be done to make sure about the safety of the products and of people walking below.
The future of flying transportation
Though the delivery drone service is alive with new technology, we are a long way from seeing them through the air. There are still many difficulties such as flight law making. It's said that by 2021 we might see the beginning of drone delivery systems in action.
①make air less polluted
②only need to pay a little
③get your product at any place
④have to send the drone back yourself
⑤get your product in less than an hour
Name | Delivery place | The product | The weather |
Tom | an airport | a sweater | windy |
Mike | a school | a book | stormy |
Jack | a house with a garden | a bottle of medicine | sunny |
Cathy | a 20-floor apartment | a fridge | cloudy |
Doing "Clean" Exercise
When you go for a run outside, chances are that you'll find rubbish all around you. Do you just go past it, or do you stop to pick it up? If you choose the second, you are part of the latest popular sport in the West: plogging.
The word"plogging" comes from the Swedish phrase"plocka upp (pick up)" and the English word"jogging (running slowly)". What a plogger needs is a rubbish bag and a pair of gloves to protect his or her hands. While collecting rubbish, ploggers learn to classify (分类) and deal with it correctly too.
Plogging seems simple but it does a lot of good to both the environment and your health. It can not only make the world greener, but also get you full body exercise. For example, a30- minute plogging burns around 288 calories(卡路里), compared to 235 calories burnt from just jogging.
So next time you go out jogging, why not carry a rubbish bag and collect some rubbish along the way? Your body and the environment will thank you.
