【推荐1】During the day, you spend a lot of time running, jumping, laughing, eating, and talking. You use up a lot of energy, and by the end of the day you’re tired.     1    

But your brain and body are not completely at rest during sleep. While you sleep, your mind may think of the things that happened during the day.     2     It also thinks about things you were worrying about, and you may wake up with answers to some of your problems.

    3     The thing called “human growth hormone” in the body helps you grow during sleep. This growth hormone also helps the body to repair itself.

    4     You use up a lot of energy during your daily activities. But when you sleep, your body temperature falls, and your “metabolism” slows down. You are still using some energy, but much less than when you are awake and active.

    5     Did you have difficulty getting up the next morning? Maybe you had problems seeing clearly. That was or you cannot think clearly. That was your body’s way of saying, “I need sleep!” A lack of sleep can stop your body and mind from working correctly.

【推荐2】When you eat a pineapple, the pineapple eats you? Now, don’t be afraid. This question is not about a pineapple monster that eats people. In fact, the common pineapple sold in supermarkets can “eat” a little bit of you.

When you eat something, your stomach breaks down its large molecules（分子）into smaller ones. In the same way, pineapples can “eat” you by breaking down the molecules.

Pineapples have certain enzymes that can break down proteins（蛋白质）. To understand this better, you can imagine a pearl necklace. Many smaller molecules—the pearls—come together to form the long necklace of a protein. You can cut a necklace with a pair of scissors. In the same way, the enzymes in pineapples “cut up” proteins.

Proteins are an important part of the cells（细胞）in your body. If an enzyme can break down a protein, it has the ability to damage cells. When you eat pineapple, the enzymes in it will “eat” the cells of your tongue. This is why your mouth will hurt if you eat too much pineapple. But luckily, the cells in your tongue will be well fast. And after you have eaten the pineapple, the special enzymes will end up getting broken down by your stomach. It won’t “eat” you anymore.

Why does pineapple have these enzymes? Some scientists believe that they are created by the plant to prevent animals from eating its immature（未成熟的）fruits. Once the fruit is mature, its enzymes won’t hurt an animal’s tongue and the fruit will be okay to eat. Another explanation is that the enzymes help the seed to mature. They send messages when to start and stop growing to the cells of the plant.

【推荐1】What do people usually put in their living rooms? Maybe you will think of something such as a TV, a coffee table or a sofa. But French designers (设计师) Mathieu Lehanneur and Anthony van den Bossche don’t think that is enough. They want to put something new in people’s living rooms. So they create (创造) a do-it-yourself ecosystem (自制的生态系统) named “Local River”. The system lets its owner (物主) grow fish and plants inside tanks (缸) in their living rooms.

In the DIY fish and gardening ecosystem (生态系统), the plants on top of the tank feed on the waste of the fish below. It makes the water clean, so the fish can go on living. In this way, the fish and plants in the “Local River” can keep the balanced environment (平衡的环境), and only need a little help from the owner. The system is also called “fridge-aquarium (冰箱水族馆)” by some people because owners can use the fish and plants as food. That is to say, owners are able to grow fish and plants in the “Local River” before eating them. Almost any plant can grow on top of the tanks and most freshwater fish are able to live in the tanks below.

The “Local River” ecosystem from Paris comes in small and large models. It is a relaxing thing to have in your home.

【推荐2】Living in a forest in the city? This sounds like something out of a fiction story. However, this has become a reality for some people in Turin, Italy.

【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 got over many difficulties to sing among the stars.

This robot writer is called ChatGPT. US company OpenAI developed it. The technology chats in a conversational way, answering questions from the Internet user. It can translate languages, talk with people and write songs, poems and even jokes. It’s one of the most powerful AI robots of its kind.

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, for example, how to make weapons(武器), it will not give you an answer.

However, ChatGPT also brings some problems. The materials(材料) they create are difficult to tell from those made by humans. This causes many problems, such as the copyright(版权) problem and the definition(定义) of art. It could also result in many translators and writers losing their jobs or being paid much less, as their skills are no longer something companies need.

It’s too soon to say what kind of influence ChatGPT will have on our lives. Let’s hope that, if ChatGPT does become bigger and more popular, its effects are mostly positive.

1. The cat story in Paragraph 1 was written to ________.

A．introduce a brave cat	B．introduce some books
C．show what ChatGPT can do	D．show how robots read stories

2. What do we know about ChatGPT?

A．It can only write songs.	B．It can do a lot of work in space.
C．It can give an answer to any question.	D．It can chat with the Internet user.

3. What’s Paragraph 4 mainly about?

A．The future of ChatGPT.	B．The disadvantages of ChatGPT.
C．The advantages of ChatGPT.	D．The development of ChatGPT.

4. What can be the best title for the text?

A．Superfast Writing Robot	B．Good Things AI Can Do
C．A Bedtime Story by AI	D．Care-providing Robot
