China’s new e commerce law came into effect on January 1. According to data from the China E Commerce Research Center, online retail sales of goods and services in China in 2017 added up to 7, 175 billion yuan. This amount made up 19.6 percent of total retail sales. Meanwhile, there are growing concerns in China about consumer protection.
The new law aims to regulate the market and create a safe consumption environment. It requires the sellers on e commerce platforms and social media to register as e commerce operators and to pay taxes as well. Those who break the law could be fined up to two million yuan.
The new law will apply to three types of operators. The first group is the e commerce platform business like Taobao. The second one is the third party merchant who sells goods and services on e commerce platforms. And the third one is the individual who does business on other network channels and websites, such as WeChat.
With the new law falling into place, consumers’ rights will be better protected. It covers rules on fake products, false advertising, returning deposits and security of personal information. Besides, the law will help clean up China’s reputation as a major source of fake products. In the long term, consumers will benefit from it.

六、阅读理解
The Internet is shaping our lives. We already have online shopping services and mobile payment. However, this is just a start. The world’s leading tech companies are planning to build smarter online communities. 36 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. 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”. 37 The bigger you smile, the more discounts (折扣) you get. Payment is done automatically through your Alipay 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. 38 It recognizes your mouth’s movements and turns them into voice 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.
39 Microsoft’s chatbot XiaoIce can not only provide useful information, but also chat with people like a real friend. XiaoIce has a WeChat account. After following the account, users can start talking with her. 40 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.
A．She knows when to comfort you or tell jokes. B．They discussed this at the World Internet Conference. C． Another type of Al focuses on understanding human emotions. D．Sougou brought its lip-reading system to the conference. E. If you smile, it will give you a special discount for your goods.
What is 5G It is the fifth generation (代) of mobile network technology. These new networks are coming.
China issued commercial license (发放商用牌照) for 5G on June 6, 2019. This means that China’s Telecom (中国电信) companies have been able to offer 5G networks to mobile phone users.

5G has a very short delay (延时) between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds (毫秒) to send and receive data.

Smarthomes
5G also makes the Internet of Things possible. Internet of Things is a large network that connects everything to the Internet. Smarthomes are part of it. For example, if its sensor feels the air becoming dry, a smart sprinkler (洒水器) can water your plants by itself.

【点睛】补全对话做题技巧。
(1)通览全文、领会大意、揣摩话题。解题时应先跳过空格通览全文，了解对话大意，根据对大意的把握，判定语境，揣摩话题。
(2)根据语境、细读选项、选择答案。在把握话题和语境的基础上，针对对话的每一空白处，细读所提供的选项，认真分析它们之间的异同，依据对话有关情景内容，选择正确的答案。
(3)通盘考虑、前后联想、先易后难。要从对话整体理解出发，依照上、下问答的逻辑顺序来考虑所选择的答案，不可不顾前后顺序，孤立地就上句就补下句，这样可能出现所补句子符合上文而不符合下文的情况。要先解决有把握的、容易的，再回头补选较难的。
(4)通读对话、义形结合、验证答案。将对话补全之后，再将整段对话通读一遍，逐一验证答案。所选的答案不仅语义上要符合语境，而且要保证语言正确，做到说话得体。
