The first friend gave him the advice that the word “hatter” wasn't needed. So John crossed out the word “HATTER” . Then he came to another friend for advice. This friend said that it was not polite to say “for ready money”. So he crossed out “for ready money”. The sign now said:

    One day a friend was passing his shop. He saw this sign and said that when a man bought a hat, he didn't care who made it. So John crossed out that word, too.
    But when another friend saw “ John Brown Sells Hats”, he said , “ Of course you sell hats. No one thinks you give them away for free.” So, at last the sign read:

    One day, three turtles decided to have a party. So they went into a cafe and ordered three cups of coffee. However, the lovely weather suddenly turned into heavy rain. The oldest turtle said to the youngest one, “Go home and get the umbrella.”

    “I will, if you don't drink my coffee.” the youngest answered.

    “Of course! We won't drink your coffee!” the other two turtles said. The youngest turtle then went to the door to leave. Time flew by quickly and two years passed. The two turtles were still at the table waiting. The oldest turtle said to the other one, “Well, I guess he isn't coming back, so we can drink his coffee.”

    At that moment, a voice came from outside the door. It was from the youngest turtle. “Oh, no! If you drink my coffee, I won't go.” he said.

Doorbells are the bells (铃) for people to ring at a door. When someone hears it, he or she can open the door. Do you know that you can ring a doorbell for fish, too? 

Every spring, millions of fish migrate (洄游) along the river in the city to find better places to lay eggs. But in the river, there are many locks (水闸). They stop fish from swimming through. Weerd Lock is in Utrecht, the fourth largest city in the Netherlands (荷兰). When fish get there, they have to wait a long time before the lock opens for boats to pass through. The lock keeper there is glad to open the lock for fish, but he cannot tell when fish want to get through. So in 2021, Mark van Heukelum, a scientist, came up with a good idea to help solve this problem—by using the fish doorbell. 

Under the water near the lock, there's a camera. People from around the world can visit a website (网站) to see fish through the camera. When you see a group of fish waiting, you can ring the doorbell on the screen. And when the lock keeper notices it, he will open the lock for the fish. 

In its first spring season in 2021, people around the world rang the fish doorbell more than 100,000 times. If you want to join them to help fish, visit the website and ring the fish doorbell next spring.

 Critical thinking(批判性思维) is trying to improve the way you think. People use critical thinking in every area of life to solve problems and evaluate claims(评估主张) Like every other skill, critical thinking takes practice. When a problem comes our way, we need to think critically to decide how to solve it. When we see an advertisement, for example, we should stop and think. Advertisements are made to make people feel certain that they are true, and then people can buy the products. But is what the advertisement says true? Is it making a claim? Or does it only int erest us? Critical thinking is important and stops us from making poor choices. In fact, we are using it if we ask questions naturally about what we see.

 Practice makes perfect. While you are growing in critical thinking, you' ll become a wiser and more thoughtful person. There are many ways of doing practice. Here are a few.

 Read about a topic people disagree on. Look at articles or books on all sides of the subject. For each side of the subject, think carefully and evaluate it.

 When you see or hear a claim, ask questions about it. Who is making the claim and why?

 Evaluate your own thinking. Where and why do you think uncritically? How can you improve? Critical thinking should be part of everything we do. It may help you to succeed at work or school. Make yourself into a habit of critical thinking. Change your thoughts and change your world.
