The Internet is shaping our lives． We already have online shopping services and mobile payment． However， this is just a start． The worlds leading tech companies are planning to build smarter online communities． （1） It was held in Wuzhen， Zhejiang last year． The development of artificial intelligence（AI，人工智能） was a hot topic at the conference（会议）． If a machine can learn and solve problems as humans do， it can be called AI．
The company Alibaba uses AI technology in its unmanned supermarket in Wuzhen． There is no salesperson in the supermarket， just a tablet on a desk that says"please smile"． （2） The bigger your smile is， the more discounts（折扣） you will get． Payment is done automatically（自动地） through your Alipay（支付宝）account． When you first enter the supermarket， the supermarket's AI recognizes your face and your account．
There is also AI that can read lips． （3） It recognizes your mouth，s movements and turns them into voices or text messages． This could be very useful when you are trying to talk to someone on your phone in a noisy place． Police could also use the technology to help them find criminal suspects by lip﹣reading recordings from video cameras．
（4） Microsoft's chatbot Xiaolce can not only provide useful information， but also chat with people like a real friend． Xiaolce has a WeChat account． After following the account， users can start talking with her． （5） She keeps improving herself by talking with users．
These technologies are being put into wider use． We may see a smarter world and better lives in the near future．

Summer schools
Summer vacation means long days，sleeping in or enjoying the summer sun．It is quite true for students to enjoy a rest after a long and difficult year．But more and more parents fear their kids forgetting a lot of knowledge，so they send their children to summer schools．Because summer schools can help children go over the knowledge that they have learnt during the school year．
In summer schools，students probably study in a more relaxing situation and can come up with interesting topics for discussion with their teachers．Usually，the number of students attending summer schools is smaller，so this gives them a good chance to connect with other students and teachers better．If a student has failed a course，summer schools may help him or her．Moreover，they are building their creativity （创造力）and imagination（想象力）as well as learning social skills．
On the other hand，summer schools bring children problems at the same time．It takes children the whole summer vacation to learn without playing．That is too long．As a result，it may make them less interested in school during the coming year．
For many students，taking summer classes can be a tiring experience．Teachers teach the subjects too quickly．which only harms the whole education of students．Summer schools are usually expensive．They usually offer only a few subject．So many students have to take classes that they don't like．
A summer school can be a good chance for students who need it，but it can be difficult for students who need a rest．SO you can decide whether a summer school is suitable for your children．
