1 . For Canaan Elementary’s second grade in Patchogue, N.Y., today is speech day, and right now it’s Chris Palaez’s turn. The 8-year-old is the joker of the class. With shining dark eyes, he seems like the kind of kid who would enjoy public speaking.

But he’s nervous. “I’m here to tell you today why you should … should…” Chris trips on the “-ld,” a pronunciation difficulty for many non-native English speakers. His teacher, Thomas Whaley, is next to him, whispering support. “…Vote for …me …” Except for some stumbles, Chris is doing amazingly well. When he brings his speech to a nice conclusion, Whaley invites the rest of the class to praise him.

A son of immigrants, Chris stared learning English a little over three years ago. Whaley recalls (回想起) how at the beginning of the year, when called upon to read, Chris would excuse himself to go to the bathroom.

Learning English as a second language can be a painful experience. What you need is a great teacher who lets you make mistakes. “It takes a lot for any student,” Whaley explains, “especially for a student who is learning English as their new language, to feel confident enough to say, ‘I don’t know, but I want to know.’”

Whaley got the idea of this second-grade presidential campaign project when he asked the children one day to raise their hands if they thought they could never be a president. The answer broke his heart. Whaley says the project is about more than just learning to read and speak in public. He wants these kids to learn to boast (夸耀) about themselves.

“Boasting about yourself, and your best qualities,” Whaley says, “is very difficult for a child who came into the classroom not feeling confident.”

6 . Before AI becomes a threat to humanity, the international community should reach an agreement on the role it is to play. More importantly, related laws and regulations must ensure that AI will benefit society and prevent it from threatening human life. Robots, for example, are believed to develop emotional intelligence sometime, which enables them to recognize, understand and express emotions in a way that is similar to humans, but we must avoid AI copying human emotions. Without legal restrictions, AI may become a social disaster.

The AI-driven new industrial revolution is irreversible. This, like previous ones, which introduced changes that had been unimaginable before, will certainly affect human employment. But it always turned out humanity was able to adapt to each industrial revolution and create new forms of employment. Therefore, it’s unnecessary to worry AI will replace our jobs. While technology advances at a rapid pace, what we need to do is to welcome the AI era rather than block its unfolding for fear of the unknown.

9 . I never knew anyone who’d grown up in Jackson without being afraid of Mrs. Calloway our librarian. She ran Jackson’s Carnegie Library absolutely by herself. SILENCE in big black letters was on signs hung everywhere. If she thought you were dressed improperly, she sent you straight back home to change your clothes. I was willing;I would do anything to read.

My mother was not afraid of Mrs. Calloway. She wished me to have my own library card to check out books for myself, She took me in to introduce me. “Eudora is nine years old and has my permission to read any book she wants from the shelves, children or adults,” Mother said.

Mrs. Calloway made her own rules about books. You could not take back a book to the library on the same day you`d taken it out;it made no difference to her that you’d read every word in it and needed another to start. You could take out two books at a time and two only. So two by two, I read library books as fast as I could go, rushing them home in the basket of my bicycle. From the minute I reached our house, I started to read. I knew this was extreme happiness, knew it at the time.

My mother shared this feeling of mine. Now, I think of her as reading so much of the time while doing something else. I remember her reading a magazine while taking the part of the Wolf in a game of “Little Red Riding Hood” with my brother’s two daughters. She’d just look up at the right time, long enough to answer– in character –“The better to eat you with, my dear,” and go back to her place in the magazine article.

10 . Preparing Cities for Robot Cars

The possibility of self-driving robot cars has often seemed like a futurist’s dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn’t leading the way here. Companies have been testing their vehicles in cities across the country. It’s hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.

While much of the debate so far has been focused on the safety of driverless cars (and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions (排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.

Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing (叫车) services.

A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure (基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues (责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.

Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn’t extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.

What does the underlined word “fielded” in Paragraph 4 probably mean?
