(2019·长郡中学新高三实验班选拔考试)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.
