William is a student of mine. His grades were really poor. I often wondered if he’d be able to pass the exam until the last few weeks of the year when we were having a class project. 【小题1】 Planting the seeds was exciting for most of the students, but the growing part was much less so. It took long time to see the results, and most kids had little patience for it.

【小题2】 Every afternoon, William made sure his seed was taken care of. In years past, few seeds sprouted (发芽). And those that did had never gotten so tall. But William’s seed was different and grew well. So before summer, I asked if he’d mind planting his young plants at school. He agreed with my idea. We picked out the perfect place behind the library. 【小题3】

About a month into the summer vacation the next year, I happened to drive by there. I wondered how the sunflowers were growing. To my surprise, behind the library, stood beautiful sunflowers. 【小题4】

At that moment, I knew I didn’t have to worry about William. 【小题5】 Others would too. And, one day, he’d bloom (开花) and shine—just like his sunflowers.

OpenAI has created a new AI called Sora and it is getting a lot of attention. Unlike other AIs that make texts or pictures, Sora can turn sentences into videos! You can enjoy these videos on any screen, big or small. Sora knows how to make scenes with many people doing different things, paying attention to every little detail. It’s also getting better at showing things the way they really look.

Sora learns by watching lots of videos and breaking them down. At first, the videos it makes are gray and look   messy. But through keeping learning, Sora improves them until they look good. ChatGPT helps too, by making it easier for Sora to understand what we ask for.

But Sora is still being tested and is not perfect yet. It sometimes has problems with complex (复杂的) actions. For example, there’s a video where a grandma blows out a birthday candle, but the candle’s flame (火焰) doesn’t move. Even though Sora has things to work on, it’s an exciting step forward in AI. It shows us something amazing in the future where AIs can make even more fantastic videos.

There are many ways to help improve your health like eating healthy food. Taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are, the longer sleep you need. But regardless of (不管) age, some people need to sleep more while for some a few hours is enough.

The problem with sleep is that more and more people in the world are not sleeping enough. According to the World Health Organization, over half the people in the world may be sleep-deprived (睡眠不足的). Having less sleep not only makes people feel tired but also causes accidents. In the United States alone, sleepy drivers cause at least 100,000 traffic accidents a year. Also sleep problems can cause medical problems such as high blood pressure.

Why are so many people sleep-deprived? Part of the reasons may be cultural. In the American culture, people put a higher value on work than on sleep. In fact, people who sleep a lot are usually seen as “lazy”. Also, you can sometimes hear some people say proudly that they don’t have much time to sleep. They only sleep four or five hours a night. It seems that the less you sleep, the more work you’ll do.

How do we teach these people to learn the value of sleep? Perhaps they may listen to the advice of Dr. James Maas, an expert in sleep. He says, “Sleep is like a credit card (信用卡). When you sleep less, you are only borrowing time. You always have to pay it back.”

For those who value work more than sleep, they should listen to what a famous person once said, “Don’t think you will be doing less work because you sleep during the night. That is a foolish idea which is held by people who have no imagination. You will be able to do more.”
