16.Lots of people buy books and products from Amazon,an online seller.They order 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 tiny flying 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 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(飛機).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 2015,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 10miles (16kilometres).
Other companies are also looking at using unmanned flying vehicles to deliver their products.For instance,Domino's Pizza in the UK released a video showing a"DomiCopter,"delivering a pizza.That video may have been a publicity stunt(噱頭).In any case,just like Prime Air's octocopters,the DomiCopters don't have clearance to take off just yet.

解答 21.答案:C.細節(jié)理解題.由第二段"And instead of waiting days to get the parcel,it could be at the buyer's home in half an hour or less."可知,不是等待幾天拿到包裹,包裹可能在半小時或更少時間送到買方的家中,因此使用Prime Air的目的是減少快遞時間.故選C.
22.答案:D.段落大意題.由第四段可知,本段介紹新的快遞方式的能力,包括試用地點,攜帶包裹重量,快遞路程,都是介紹這種方式.故選D.
23.答案:A.推斷判斷題.根據(jù)最后一段的內(nèi)容"Other companies are also looking at using unmanned flying vehicles to deliver their products"可知,其他公司也在嘗試用無人駕駛飛機運送產(chǎn)品.故可推測出這項運送服務(wù)正在進步.故選A.
