【推荐1】Many people like animals and keep one or more as pets—dogs, cats and some kinds of birds. If you keep a dog or a cat as a pet, you must know how to look after it. A grown-up(成年) dog needs two meals a day, not more. And it can eat meat, fish, rice and some other things. Dogs like big bones(骨头), but don’t give them chicken bones. Remember to give them much clean water. A dog should have a clean, dry box for sleeping. Washing it once a week is good for its health. If it is ill, take it to a doctor. A healthy dog will bring you more happiness.

Be careful when you have chosen(选择) a cat. It has two meals a day with some meat or fish. Cats drink a little milk every day. Sometimes give them vegetables to eat. Don’t forget that they need clean water to drink.

Take good care of your pets. They will be your good friends. Maybe they can give you some help when you need.

【推荐2】Most animals on land are known to us, but many living things underwater are not. Now let’s get to know some of them.

Sea cucumber

Sea cucumber are strange animals living at the bottom of the sea. They wear brown or pale green coats with many sticks up. When summer comes, they stay deep to sleep because they are afraid of heat. And when it is autumn, they move to shallow (浅的) water and get their food.

Pike

The pike is a kind of freshwater fish. They are good swimmers and like swimming near boats, waiting to be fed. They have sharp teeth to catch fishes. When they are young, they live in groups. However, when they grow up, they prefer to live alone.

Cuttlefish

A cuttlefish can swim quite fast, so it is also called rocket (火箭) fish. It has eight arms and two feelers on its head, just around its mouth. It ejects ink (喷墨) when it is in danger. Its meat is delicious, and it is often the first choice for many people.

Octopus

An octopus has long arms, with which to catch food and protect itself. When it is sleeping, one or two of its arms are still on duty, keeping moving. Once it feels something dangerous, it can wake up at once to take action.

ChatGPT is back in the headlines! OpenAI, the company behind the popular chatbot, has now introduced a powerful new language model: GPT-4.

On March 14, GPT-4 showed the world how smarter it is than the previous GPT-3.5. One of its best new features is that it can understand pictures. For example, if you show a picture of a phone using the wrong charger (充电器), GPT-4 can tell why the picture looks strange or funny.

But GPT-4’s developments don’t stop there. The new language model can code (用代码编写) classic games in a matter of minutes, and produce the code and layout for a website based on a hand-made drawing. It can also change the tone and style based on what you ask it to do. GPT-4 is much better than the older GPT at passing tests, which may worry teachers. According to CNN, GPT-4 did really well on a law school test, with a score in the top 10 percent of test takers. But GPT-3.5 only got a score in the bottom 10 percent.

GPT-4 will also see greater use as a tool to power other apps and services. For example, the language learning app Duolingo plans to use GPT-4 in their upcoming Duolingo Max function. Users can learn language by talking with AI. Another app, Be My Eyes, will have a digital assistant to help blind people better understand the world around them. The government of Iceland also plans to use GPT-4 to protect the Icelandic language.

There are still problems with the new language model, however. GPT-4 still struggles to get completely correct answers, especially with newer information after September 2021. GPT-4 also sometimes “hallucinates (产生幻觉)”, meaning that it will insist that wrong information is true.

【推荐2】How old will you be in 2029? That is how old you will be when a large asteroid (小行星), called Apophis, comes very close to our planet. Asteroids move around the Sun in space and sometimes come close to the Earth and even hit it. Most asteroids are very small. If you are lucky, you can sometimes see them in the night sky as "falling stars".

However, most scientists believe that one large asteroid hit the Earth and killed all the dinosaurs about 65 million years ago. It was about six to twelve kilometers across. Apophis is also big. Scientists found it out in 2004 and they said that it is about 300 meters across. It is as large as a large sports field. According to scientists, such size is not large enough to destroy (破坏) our world, but it is large enough to destroy some cities. It will probably miss (未击中) the Earth in 2029, but it will come very close to the Earth. It is only about 35,000 kilometers away. That's much closer than the moon, about 240,000 kilometers away. Another way of thinking about it is that it will miss us by only a few minutes.

If you don't feel afraid, then think about this: the same asteroid will visit the Earth just a few years later. In 2036, it will visit the Earth again. Again, it will miss our planet, but again very near...The only sure thing is that all the eyes and telescopes in every country of the world will watch the skies.
