    China's largest search engine Baidu has said it will make its latest artificial intelligence (AI) technology accessible to developers and businesses as part of the company's latest move into AI, big data and cloud computing.

    AI solution "Tianzhi" was launched at a cloud-computing summit held in Beijing Wednesday. It includes services in three fields: sensing technology, such as image and voice processing, machine learning, and deep learning, an advanced form of machine learning, said Zhang Yaqin, CEO of the Nasdaq-listed company, at the summit.

    Developers can access facial or voice recognition, algorithms(演算法) for data analysis and projections, and deep learning applications, Zhang said, adding that the technology could help users innovate in their sectors.

    "With more devices connected to the cloud, enterprises will use cloud computing and AI more frequently," said Wu Hequan, an academician at the Chinese Academy of Engineering, "Open AI technology can play a bigger role."

    The company also revealed a plan to invest 10 billion yuan (1.45 billion U.S. dollars) in cloud computing in the next five years and establish an innovation center, which will serve 10 million enterprises.

    My roommate Lily was well organized, while I was not. Each of her objects had its place, but mine always hid somewhere. She even labeled (贴标签) everything. I always looked for everything. Over time, Lily got neater and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.

    War broke out one evening. Lily came into the room. Soon, I heard her screaming. “Take your shoes away! Why under my bed!” Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder.

    The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Lily answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled (爬) under her covers, sobbing. Obviously, that was something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart.

    Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn't notice Lily had sat up. She was watching, her tears dried and her expression one of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me, “Thanks.”

    Lily and I stayed roommates for the rest of the year. We didn't always agree, but we learned 高一阅读理解My roommate Lily was well organized while I was the key to living together: giving in, cleaning up and holding on.

    Daily physical activity is an important part of a healthy lifestyle. For this reason, many architects and designers are working to create buildings that encourage people to make exercise a part of their ordinary routine. The movement to promote healthy activity through architecture is called active design. It began in 1998 as part of a university public health program, and it has since gained popularity in cities around the world. Active design uses a number of techniques to encourage the occupants of a building to be more active.

    One of the most important strategies of active design is inspiring people to make walking part of their routine. A particularly successful tool for promoting walking is the skip-stop elevator. These elevators stop only on every second or third floor, leaving riders to take the stairs in order to reach their destination. Another strategy of active design is to make stairs more pleasant and inviting. Instead of creating dark stairwells that are located in isolated parts of buildings, active design uses well-lit and centrally placed stairs to encourage more foot traffic. Skip-stop elevators and appealing stair design are both effective tools of active design because they offer incentive and opportunity for exercise. In fact, researchers studying a building that employs both skip-stop elevators and more attractive stair design said that 70 percent of building occupants reported using the stairs every day.

    Active design encourages physical activity using not only the interior features of a building, but the relationship between a building and its surroundings as well. A building that employs active design may integrate outdoor space in order to make the environment more engaging and promote physical activity. Some elements that architects use to incorporate the exterior with the interior are glass walls, interior gardens or park spaces, and courtyards with open ceilings, all of which de-emphasize the boundaries between inside and outside. These elements make the building more physically and mentally invigorating. Similarly, by increasing the number of entrances and exits to a building, architects can help keep a building's users interested in their surroundings by providing a variety of routes for them to use. If people continue to be stimulated by new sights or experiences, they are less likely to choose the quickest and easiest path to their destination and may instead choose a more physically challenging route.

In a normal year, Dayna Reber, a business analyst for a technology consulting firm in Camp Hill, Penn., would finish reading around three books. Thanks to the way Covid-19 has completely changed her daily routine, however, Ms. Reber, 30—who now works from home and rarely socializes offline—has polished off 46 volumes so far in 2020. And that count doesn't include the bedtime stories she reads to her 4-year-old.

For Ms. Reber and others, lockdown has brought back a passion for reading, both as beneficial time-filler when stuck at home and as a trusty escape. "When the coronavirus hit, I just felt a need to get away from TV and screens."

If binge (放纵地) reading hasn't fully replaced binge-watching Netflix shows quite yet, the trend is certainly making strides. In August 2020, year-over-year sales of print books in the U.S. were up 13%, according to NPD BookScan, which tracks book sales across the U.S. Publishers also report a notable increase in purchases of e-books, as well as all books about politics or related to civil rights, racism and diversity.

Independent booksellers, as well as publishers and authors, deserve considerable credit for fueling the page-turning trend. In March, Octavia Books introduced free shipping or delivery within New Orleans on orders of $25 or more. The bookstore also hosts author events via Zoom. And in Illinois, Page 1 Books established a subscription service, where customers fill out an online profile, noting their literary tastes, and then receive a package each month, a mix of hardcovers and paperbacks.

Jamie Miller, 34, a book blogger and "book-stagrammer" who lives in Harleysville, Penn, has long been a committed reader, but she says the hobby has meant far more importance this year. She now schedules a block of time every morning to read, typically a love or vivid novel. "Everything became so chaotic around me that it was just like what can I control?" said Ms. Miller. "My brain just wants something guaranteed to be a happy ending."
