1 . Artificial Intelligence (AI) is a technology that lets machines do things that require “thinking”. It is a hard term to define (下定义) because AI isn’t actually one thing. Rather, it’s a group of technologies that help machines acquire, understand and use information to perform tasks. The range of technologies is one of the reasons people use so many different terms when mentioning AI.

Recent developments of AI have received a lot of media attention. Although some have welcomed the technology because of things that AI makes possible, the attention has also produced a lot of fear and caution. In particular, many are concerned about the effects AI could have on people’s jobs.

Unfortunately, the media excitement is often a distraction (令人分心的事物) that causes people to miss an important point. Since AI isn’t just one thing, we aren’t waiting for it to be invented. Rather, the technology is experiencing a long development process. AI isn’t coming. It’s already here. We aren’t living in a world controlled by computers-yet. But we are living in a world that relies more and more on AI for better efficiency.

Newspapers, design companies and film studios are all making use of the technology. Often the technology is used to do the heavy lifting of repetitive tasks so that professionals can work more productively. Admittedly, the tasks AI does are often the things done by low or entry-level employees. But that hasn’t necessarily spelled the end for human workers.

In recent years, for example, AI-driven translation has dramatically increased the amount of   material a human translator can process each day. But the easy availability of translation has also led to an increased need for translators. As a result, the industry and its human translators often struggle to keep up with demand.

There is no doubt that AI is changing how we live and work in very complex ways. That makes AI an important trend to watch, but not to panic about yet.

2 . More than 30,000 people went to the White House on Monday for the 136th Easter Egg Roll (复活节滚彩蛋). President Barack Obama and First Lady Michelle Obama held the event by inviting thousands of kids to color and look for eggs. The theme(主题) of the day was “Hop Into Healthy, Swing Into Shape.” It was part of the First Lady s“Let' s Move!”program to reduce obesity rates (肥胖率) among American kids. Mrs. Obama spoke to young reporters about her goal(目标) to get children to eat right and keep moving.
“We are working to make sure that kids born today grow up healthy, learn how to have balanced meals, and get more physical activity into their lives,” she said.
Mrs. Obama said she wants children across the nation to understand that "exercise isn't just hard work, it' s play. If you're running around with your dog, you're getting exercise. If you walk up the stairs, that's exercise. But if you're sitting in front of the TV or on a computer game, you're not exercising.”
The First Lady said that for kids who have balanced meals most of the time, having a special snack, like chocolate, will not hurt. "And if you are active, you can splurge (挥霍) a little more," she said. Mrs. Obama’s favorite "splurge food" is French fries. But she balances her splurging by exercising almost every day. She loves to play tennis and she practices yoga.
“A lot of kids look up to(敬仰) athletes, and I think it's important for athletes to share their good habits,” Mrs. Obama said. "Kids aren' t just going to wake up and be LeBron James. He's practicing and eating right and working out and training. Our athletes can be really good messengers to kids who look up to them — they can say to kids, ‘If you really want to be like me, then you really do need to eat your vegetables.’”

3 . At three a.m., Jack Mills was sitting at the controls of the mail train. The train was made up of 13 cars. At the end of the train, 71 mailmen sat sorting the mail.
