Last Saturday, mom and I went to buy a down jacket for my grandpa. When we got to a big store, we saw down jackets of vary colours and styles. There were so many of them that it spent us quite a while to decide which one to buy. Finally, under the help of the shop assistant, he selected a black thick jacket for grandpa. Immediately, we returned back home to show it to my grandpa. Seeing it, he was very happy and couldn’t wait to put on. But we were annoying to find something was wrong with the zipper. Hurriedly, I took it back to the store and explained the shop assistant the problem To my satisfaction, she is very kind and helped me choose another one patiently. Stand in front of the mirror, my grandpa looked at himself in the new coat, smiling contently. How delighted I was!

Amazon Introduces a Digital Music Locker
Amazon.com, plans to introduce a service that will let people upload their digital music to the Web from anywhere. 1.
The service, known as a music locker, was made available to Amazon account holders early Tuesday．Amazon will offer a Web-based hard drive backup service called Cloud Drive, where people can store documents, photos, videos and music．
It will also offer Cloud Player, which will let people listen to, download and make play lists from the music they store on Cloud Drive from any Web site or from an app on Android devices． Cloud Player will automatically upload songs bought on Amazon． 2.
3. One key difference is that Google and Apple reportedly want to automatically make all the music that a user owns available to stream on other instruments, while Amazon will require that people upload music, except songs they buy on Amazon, to access it elsewhere．
The dream of these companies, along with many start-ups, is for people to be able to listen to their music from any computer or phone． 4. Several experts in digital music say that the music locker business is still legally ambiguous． 5.
Amazon says it has avoided the problem, because its users would upload their songs, in MP3 to the cloud-based service, just like backing them up on an external （outside） hard drive or a Web-based computer backup service．
Companies, including Google and Spotify have been forced to delay introducing certain services while they negotiate with the music labels and publishers．
A．People can access it from any computer and from Android phones．
B．But they have all run into the same problem: music companies and publishers would prefer that listeners buy a new copy of a song everywhere they want to listen to it．
C．Experts suspect that Amazon seems to be copying what Google and Apple have already achieved．
D．They agreed to speak on the condition of anonymity （匿名） because their agreements with Amazon are confidential．
E．It is impossible for Web companies to tell whether a song was bought legally or downloaded illegally．
F．Amazon is racing Google and Apple, both of which are interested in offering similar services．
G．It will also scan iTunes or Windows libraries to find other music to upload．
