文章大意:本文主要讲关于猫的一些事实,劝人们不要相信一些荒诞的说法,好好照顾猫。

1 . We sometimes have the wrong ideas about the things around us, for example, some things about cats that people believe might not be true. These myths (荒诞的说法) can make cat owners confused (困惑的). Let’s learn the truth about them.

Some people think that cats need to drink milk. That is not true. If a cat eats well, it does not need to drink milk. Does your cat drink milk? Most cats like milk, but too much of it can make them sick. They can only have a little milk.

Some people put garlic in cat food. They believe it will keep worms (寄生虫) away from a cat’s body. Does it work? No, it does nothing to worms. It will give the cat bad breath! If your cat has worms in its body, take it to see a doctor. The doctor will give medicine to the cat.

Some people think that a cat’s whiskers (须) can help it keep balance (平衡). In fact, whiskers have nothing to do with balance at all. They help the cat know about things around.

文章大意:本文主要介绍了不同动物的睡眠方式和时间、人的睡眠时间以及人体各部分在睡眠中的活动。

6 . Everybody knows that cats like to sleep. They spend more than half of their lives sleeping and enjoying every minute of it. Other animals have different sleeping habits, however. Horses may not look like they are asleep. But they are! Horses spend about six hours sleeping every day and they do it standing up!

Fish also sleep every day but they have a strange habit. They don’t close their eyes when they are sleeping. When ducks sleep, they keep one eye open and one half of their brain (大脑) awake. It helps them stay alert (警惕的) and watch out for dangerous animals.

So what about us? Well, most people sleep for about a third of their lives. The number of hours you sleep, however, has to do with your age. Most newborn babies sleep a lot. They spend about 75% of their time sleeping every day! As we get older we need less sleep. Children need about eleven hours and adults sleep for eight hours every night. So, yes, you spend many hours a year doing nothing—sleeping in bed!

But you are not just asleep—you are not really doing nothing. Your body and your mind relax during this time, but a lot of things happen during sleep. Dreams are one way that the mind relaxes after a busy day. A person spends about 20% of every night dreaming. That means you have about four or five dreams every night or about 1 ,600 dreams a year.

文章大意:本文讲述了地震频发的当下,科学家如何预测地震的未来。

9 . Usually before an earthquake happens, people don’t know it is on the way. And these earthquakes are very dangerous. In fact, earthquakes kill more people than snowstorms and rainstorms every year. So scientists are always looking for ways to predict earthquakes.

Now they can predict the earthquake, but it is not always right every time. And scientist can say that an earthquake is possible to happen in some place, but they can’t predict the right place or time. And they can not tell how strong the earthquake will be.

Second, to help predict earthquakes, scientists study history of the areas where earthquakes happened. Studying the history can also help in another way. Scientists can guess how often an earthquake may happen in this area. Last, scientists watch rocks under the surface for months. When rocks break, earthquakes happen. And scientists also watch the water level to predict an earthquake.

Scientists hope that one day we can have earthquake warnings.

Who do works created by AI belong to? Here’s an answer.

A man made a picture by     1     AI in February. And then, he posted the picture on Xiaohongshu. However, a lady used the picture in March and     2     off the Xiaohongshu watermark(水印).

The court (法院) found that this was against the law and     3     the lady must pay 500 yuan to the man.

The law is still not clear     4     AI-made works like this. Decisions on such problems are expected to change     5     over the next several years.

How to recognize an AI-made picture?

1. Look at     6    . AI often draws human hands wrong. Sometimes the number of fingers is not right, and sometimes the shape looks     7    . The photos AI uses to learn often show hands in different gestures (姿势), so it isn’t sure     8     a “hand” really looks like.

2. Pay attention to the details. For example, people in an AI-made picture may     9     an earring or apart of their glasses. If there’s text in an image, such as a poster, the text is usually unreadable.

3. Check the background. AI is also terrible at dealing with the background. If there’s crowd in the image,     10     faces in the corner are not clear or they don’t have a face at all!
