Unit 5 Meeting your ancestors
一、阅读理解。
Four years ago，we asked ourselves：What if we could create a shopping experience with no waiting in line and no checkout? Or could we create a physical store where customers could simply take what they want and go? Our answer to those questions is Amazon Go，where you could experience the idea of “just walk out shopping”．
Amazon Go is a new kind of store with no checkout required.We created the world's most advanced shopping technology，so you never have to wait in line.With our“just walk out shopping” experience，simply use the Amazon Go app to enter the store，take the products you want，and go！No lines，no checkout.
Our checkoutfree shopping experience is made possible by the same types of technologies used in selfdriving cars：computer vision，sensor fusion，and deep learning.Our “just walk out technology” automatically detects when products are taken from or returned to the shelves and keeps track of them in your virtual cart.When you're done shopping，you can just leave the store.Shortly after，we'll charge your Amazon account and send you a receipt.
We offer delicious readytoeat breakfast，lunch，dinner，and snack options made fresh every day by our onsite chefs and favorite local kitchens and bakeries.Our selection of foodstuff ranges from bread and milk to cheeses and locally made chocolates.You'll find wellknown brands we love，plus special finds we're excited to introduce to customers.For a quick homecooked dinner，pick up one of our chefdesigned Amazon Meal Kits，and you can make a meal for two in about 30 minutes.
Our roughly 1,800squarefoot shopping space is conveniently compact(紧凑的)，so busy customers can get in and out fast.It is located at 2131,7th Ave，Seattle，WA，on the corner of 7th Avenue and Blanchard Street.All you need is an Amazon account，a supported smartphone，and the free Amazon Go app.
Amazon Go is currently only open to Amazon employees in our testing program，and will be open to the public soon.

【解题导语】本文是一篇说明文，主要介绍了有关Amazon Go便利店的一些信息。
【难句分析】Or could we create a physical store where customers could simply take what they want and go?
分析：该句为主从复合句。句中where customers could simply take what they want and go为where引导的地点状语从句，修饰先行词store；其中take后接what引导的宾语从句what they want and go。
译文：或者我们能不能创建一家实体店，在那里顾客只要拿走他们想要的东西然后离开？
1．A 考查细节理解。根据第二段第一句“Amazon Go is a new kind of store with no checkout required”可知，Amazon Go便利店无需在收银台结账，故A项正确。B项文中没有提及；根据文章最后一句“Amazon Go is currently only open to Amazon employees in our testing program，and will be open to the public soon”可知，Amazon Go目前仅处于试营业阶段，仅对亚马逊员工开放，故C项错误；根据第三段第一句“Our checkoutfree shopping experience is made possible by the same types of technologies used in selfdriving cars：computer vision，sensor fusion，and deep learning”可知，Amazon Go使用的技术类似于无人驾驶汽车的技术，故D项错误。
2．B 考查段落大意。通读第三段可知，该段主要介绍了无人收银的技术原理，即类似于无人驾驶汽车的技术；还介绍了顾客付款的技术原理。据此可知，该段主要介绍Amazon Go便利店的运作原理，故B项正确。
3．C 考查细节理解。根据第三段最后一句“Shortly after，we'll charge your Amazon account and send you a receipt”可知，在顾客离开后，Amazon Go会通过亚马逊账户收取顾客的费用，故C项正确。
