（36）F In the books of J．R．R．Tolkein，Bilbo Baggins finds a ring that can make him disappear．Of course，there's also poor Harry Potter，who used his invisibility cloak （隐形斗篷）to hide from danger．
Now that you've got some ideas，it's time for the hard part：building the cloak．（37）G An invisibility cloak has to cheat anything or anyone who might be watching．In order to understand how something can be seen，it's important to understand how we see．

According to an industry report，China's B2C （Business to Customer） online sales are growing at an annual rate of 25percent．Competition between online giants like Taobao and Jingdong is now fiercer than ever．"The  essence of online shopping is that customers can buy products easily．So the competition is about：firstly，the range of products； secondly，the depth under each category of products； third，the price and user experience，"Pan Biao，vice president of YHD．com，said．E-commerce is one of China's fastest growing sectors．It's changed people's buying habits，and even their living habits．And it's had a huge impact on the retail industry．To make online shopping more convenient，major sites are investing heavily to build payment systems and logistics（物流）networks．
