【推荐1】3-D films are not new. People first watched them in 1903. The inventors wanted people to feel like they were really inside the film they were watching! When you watch a 3-D film, you feel as if the people on the screen (屏幕) are near enough to touch and that the plane flying at you is flying off the screen. To watch 3-D films, you may need to wear special glasses. Usually, people buy or borrow the glasses in the cinema. But do you want to make one pair by yourself?

Here are tips for making your own 3-D glasses.

①Get some cardboard. Cut out the shape of glasses. Make sure you can see through each hole (洞) when you hold it up to your eyes.

②Get some red and light blue acetate (醋酸透明塑胶片).

③Glue (粘贴) the blue acetate on the right hole and the red on the left one.

Next time when you go to watch a 3-D film, don’t forget to take your own handmade glasses!

【推荐3】Type in “A cat wants to go to space” and ask the robot to write a bedtime story. Just one second later, you’ll get the story of Max, who was on his way past many difficulties to sing among the stars.

This robot writer is real. It’s called ChatGPT. From writing Shakespeare-style poetry to making music, ChatGPT has amazed the world since its launch out in late 2022 by the US company OpenAI. OpenAI developed it to generate (生成) human-like texts. It can translate languages, talk with people and write songs, poems and even jokes. It’s one of the most powerful AI of its kind, with the complete writing abilities of a real person!

People around the world have tried ChatGPT and posted their results on social media. Some used it to write history reports, some asked it to take notes of presentations, and some even generated advice on how to communicate with people at a party, reported The Atlantic.

The power of ChatGPT lies in its speed and understanding of complicated (复杂的) matters. We may spend hours researching, understanding and writing an article on the theory of evolution (进化论). But ChatGPT can produce a well-written one in seconds. Another good thing about it is that if you ask dark, harmful questions, such as how to make weapons (武器), it will not give you an answer.

ChatGPT comes along at a time when AI is becoming increasingly able to do creative tasks. There is no doubt that ChatGPT is a powerful tool. However, some schools in the US, Australia and France have banned (禁止) the use of ChatGPT. In the US, for example, New York City public schools banned students and teachers from using ChatGPT on the local networks and computers, CNN reported. The move comes out of worries that the tool could make it easier for students to cheat on homework. Some also worry that ChatGPT could be used to spread improper information.

“It does not build critical-thinking (批判性思维) and problem-solving skills,” said Jenna Lyle, the deputy press secretary of the New York City Department of Education. “The materials they create are difficult to tell from those made by humans. This causes many problems, such as the issue of copyright (版权). Since the system is largely trained using words from the Internet, it can also pick up on the Internet’s biases(偏见) and stereotypes (刻板印象) about certain groups. These are all the things that depend on humans to solve.”
