On Tuesday, Baidu, a Chinese search engine and artificial intelligence firm, released a new version of its artificial intelligence model, Ernie 4. 0. Baidu's CEO, Robin Li, 【小题1】 demonstrated it at the 【小题2】 (company) annual Baidu World conference in Beijing, said the model was able to understand complex questions and instructions and employ reasoning and logic 【小题3】 (create) answers to questions.

In a live demonstration, Li asked Ernie 4. 0 to generate advertising 【小题4】 (material) including posters and a marketing video. He also asked Ernie 4. 0 to come up with a novel complete with characters with 【小题5】 (variety) personalities.

Li said that 【小题6】 technology can transform how certain products work. Baidu's search engine can generate a customized answer to a query (查询) instead of just 【小题7】 (provide) a list of results and links.

Beijing-based Baidu started off as a search engine firm and over the past decade has invested 【小题8】 (heavy) in artificial intelligence technology such as autonomous driving 【小题9】 more recently, generative AI to stay competitive.

At present, Ernie 4. 0 【小题10】 (be) not yet available to the general public, but some people have been invited to try it.

Digital receipts offer a few improvements over 【小题1】(tradition) paper receipts. One is health-related. Lots of receipt paper contains bisphenol—A, or BPA. This chemical can completely influence or outright change some bodily processes, like hair growth, hormone function and cell repair. 【小题2】 (reduce) receipt paper reduces the risk for BPA exposure for not only consumers but also for employees who handle the paper 【小题3】 a more routine basis.

Another reason why digital receipts are better just boils down to 【小题4】 (convenient). You can access those receipts through your email and file 【小题5】 (they) away in a separate folder or with a specific label for easy sorting. Or, if you need more help on the organization front, try a receipt tracking app. Physical receipts require you physically 【小题6】 (keep) track of them, and that means a shoe box or an accordion folder or a big thumb tack on a cork board in the kitchen. There have been times when I’ve let something go unreturned 【小题7】 I didn’t have the receipt. I’m betting I’m not alone on that.

Some businesses, particularly local ones, use newer point of sale systems like Square that will 【小题8】 (automatic) send you a digital receipt if you’ve already received one from another business that uses Square. When you pay with the same credit you did at the first seller, and you’ve already provided 【小题9】 email address to the Square system, you 【小题10】 (get) a receipt in your email minutes later.

Nearly two decades【小题1】 (pass) since China sent the first Beidou satellite into space in 2000. During that time, more Beidou satellites were sent into orbit (轨道), 【小题2】 (form) the Beidou Navigation Satellite System (BDS). In late 2012, it began providing positioning, navigation, timing and messaging 【小题3】 (service) to people in China and other parts of the Asia-Pacific region. At the end of 2018, BDS started to serve users worldwide. Now with two more Beidou satellites 【小题4】 (launch) on Dec 16, 2019, BDS has 53 satellites in orbit.
