My two little daughters and I usually go out and help others on Thankful Thursday. Last Thursday we were going to buy lunch for the beggars（乞丐） in the street. Then we went to the nearest McDonald's. I ordered 15 lunches from it and drove my car to hand them out.

We gave the lunches to the beggars. They were excited. We were happy to see that.

    Then we noticed a small, old woman, asking for pocket money. We gave her our last lunch bag. Before we got into the car, she started to speak to us, "No one has ever done anything like this for me before, "she said with a smile. "Well, I'm glad that we were the first, "I answered. "So, when will you eat your lunch," I asked.

    She just looked at me with her big, tired brown eyes and said, "OH, dear, I'm not going to eat this lunch. You see, I have a little daughter. I usually can't buy her favorite food, but today she will be so happy!"

    I don't know if the kids noticed the tears in my eyes. I have asked many times whether our actions of kindness were too small to change anything. Yet at that moment, I realized the truth of words: "We cannot do great things —only small things with great love."

    Ding-dong!

    "Jason, honey? Can you answer the door?"

    "I'm busy, mom!" Jason shouted back at his mother. He'd spent three hours so far working to his point in the gate. He couldn't stop now.

    Ding-dong! Mom's footsteps approached the front door.

    "Jason, it's your friend, Todd." Mom called from the doorway.

    Todd, his best friend, stepped into the room. "Jason! I need a partner for playing basketball. He sounded excited.

    Jason snorted, "No way, Todd. I'm playing a game here."

    Todd shook his head. "You can play later. Let go."

    Jason gave his friend a dirty look, and his character in the game almost got killed while he looked away, "I almost died because of you!

    Todd looked at Jason's mother. Jason's mother looked back at him. They both looked at Jason. "Why don't you play basketball with your friend?"Jason's mother suggested.

    "Tomorrow, maybe." there were more levels to beat tomorrow, though. Maybe he'd play tomorrow. He'd have to see what mood he was in. He thought he heard footsteps walking away, but he was too busy beating the next level to care.

    An hour later, Jason's father came home. It was dinner time after his father washed up and sat down. Jason didn't even hear his name being called to the table. He didn't hear his father walk up behind him and ask him to turn the game off, either.

    When the screen suddenly went black and his father's angry face loomed in front of him, Jason finally heard. "No more game for a month." Jason's father shouted at him. "You don't play basketball, you don't come to dinner, and you don't do your chores. We'll make sure everything else gets done before you play anymore."

    Jason nodded slowly. He knew better than to argue with father, and when he thought about it, he had been playing quite a bit. It was fun, but he was letting down(使失望) his friends，his family, and himself by playing too much.

    He'd try harder in the future.

AI (人工智能) makes our lives easier and better. Let's see the interesting AI.

①Yellowknife, Whitehorse and Come By Chance — all are names of towns and cities in North America. Ottawa, Beijing, Paris, Hanoi and Tokyo — all are important world cities. But how did they get these names? And why?

②Some names sound funny, and some of them make no sense when you first hear them. But there is always a story or a tradition behind a name. People live in an area. A city begins to grow. In the beginning, it might have no name, but soon, people start calling it something. When enough people use this name, it usually sticks. And a new city name is born.

③In the tradition of East Asia, important cities are given names that tell us exactly what they are, and where they are located (位于). Nearly everyone will know that Beijing means "northern capital". But do you know that Tokyo and Hanoi mean "eastern capital"?

④Ottawa, Canada's capital city, was given its name thousands of years ago. It is located at a place where two rivers meet, and was a place where Indian nations came to trade with each other long ago. In the native (当地的) language, Adawe means "to trade". When the Europeans lived in the area, they heard the natives calling the place Adawe. This sounded like Ottawa to the European ears. Soon enough, everyone was calling the city Ottawa.

⑤When a European explorer (探险家) arrived at a place in the far northern area of Canada, he found native people carried huge knives made of copper (铜), which appeared yellow in the shining sun. The explorer decided to call them Yellow knives. He named the place where they lived Yellowknife.

⑥Next time you hear an unusual city name, see if you can discover how it got that name.

I always told my children that they were smart all the time. Especially in the first years of their life, they learned skills and language so quickly. I had a particularly clear memory of watching my son work out how to play a Lego toy and I told him, "You' re a such architectural(建筑的) genius. Mom is proud of you."

 But some research suggests that we should not tell our children they' re"smart" when they do important things. When I first heard about it, I disagreed. But after doing some research, I gradually agreed. It all goes back to"growth mindset", which means that you can change your abilities through hard work and strategies(策略) . Compared to a"growth mindset", a"fixed mindset" is the idea that your abilities are inborn and can't be changed. When we praise our children for being"smart" based on success, like solving a problem or doing well on a test. we' re encouraging them to believe that if they do poorly or make mistakes, they' re not smart.

 And it's not just what we say about our children's success that matters — it's how we tolerate(容忍) their failures. A study led by a scientist named Kyle shows if parents think that failure is shameful, their children are more likely to be derailed by mistakes. For example, Dr. Kyle explains, your children may have difficulty in solving math problems and you may say something like"Not everyone needs to be good at numbers" as a way to comfort them. But what you' re really doing is suggesting that their math abilities are already set, and can't be changed.

 Whatever you say to your kids, it's about getting them comfortable with failures. Here are some tips from Dr. Kyle. One way is to praise kids' hard work instead of their intelligence. As Dr. Kyle pointed out, if we praise a kid for a school project he finished in five minutes, he would know our praise is empty. Instead, we can ask him questions about how he did it, which can help us know how to praise future hard work. Also, we can talk about our mistakes. We don't have to hide our negative(消极的) feelings. If we point out our missteps and explain how we insisted, our children can learn to do the same.
