We often find that weekends and holidays feel so short while classes and work feel so long. Actually, though, we know that this is not true. But we still wonder where that strange feeling comes from.

    In fact, this is one of the ways that we're tricked by time, according to the website. All that S interesting. The website lists several wrong impressions (印象) we often have about time. Let's have a look.

    First of all, emotions affect (影响) our time-keeping abilities. Negative emotions (消极情绪). especially anxiety and boredom, make time seem longer because they make us concentrate (集中) more on the passage of time. However, when we are enjoying ourselves, we pay more attention to what we are doing and are likely to lose track of (失去对……的意识) time.

    Here is another example. In 2007, a group of scientists carried out a test. In the test, people fell 50 meters into a safety net and were then asked about their experience. Although the experience took shorter than 3 seconds, the people thought it was much longer than it actually was.

    This is because of the way our bodies reply to danger, according to the scientists. Our bodies produce a chemical called adrenaline (肾上腺素) when we are faced with danger. It allows us to concentrate better so that we can stay alive. As a result, we are able to remember far more details (细节) over a short period of time, which makes it seem like time is going more slowly.

    Another situation when we make mistakes about time is when we take afternoon naps (午觉). Have you ever had trouble telling what time it is after a long nap? That's because the best amount of time for a nap is 20 minutes. After 20 minutes, you enter a new stage of sleep called slow-wave sleep. If you wake up mid-way in this stage, it will take a while before you can correctly perceive (感知) time again.

    Yes, time can be mysterious (神秘的) and there is no way to control it. So, perhaps the best thing to do is to make good use of every minute.

Do you miss the great snacks you had when you were a kid? Do they help you remember your happy childhood?

Protect Man's Best Friends

Animals and plants are our best friends. They help us a lot in our daily lives.

We have learned English for several years, so we can read English books and magazines without the teachers' help. We feel good when we finish 1 an English story or a whole book 2 ourselves. But3 can we be a better reader?

It is important 4 some suitable books. Then what books are suitable? Well, I think we should first choose books that are not too difficult or too 5 . Then when we are reading, we should 6 let new words take too much of our attention. Just do as we often do in our own language. While we are reading, try to 7 the meanings of the new words, and try to decide which of the key words we could guess and which we have to 8 in the dictionary.

If we follow these 9 , we will be10 in reading English books and magazines.

Have you ever imagined being able to communicate with your pets at home and have them understand everything you say？It sounds too good to be true，but scientists have started using AIto help communicate with animals. 

Professor Bake told Scientific Magazine that AI allows humans to use technology to watch and understand the sounds and signals animals communicate with so we humans can try to speak back to them. She said trying to communicate in animals' language could be better than teaching them how to use human sign language. AI is already helping us communicate with bats and bees. This could change what we know about these animals and our relationships with them. 

Professor Bake explained how Scientist Tovel had used recordings and AI to understand bats. "Bats have their own language. They often argue over food. They have different names，or 'signature calls'，" she said，mother bats lower their voice when speaking to their babies. Their voice can never be heard with human ears. But AI makes this possible because a computer can be trained to listen like a bat. "

Actually，AI has so far achieved a lot in this field. For example，the computer not only listens but also watches bees' body movement to understand what they are communicating. Bake said scientists now know how bees say things such as "be quiet" or "stop". Scientist Landlof even created a robot Honeybee that entered a bee's home and was able to communicate with other bees when it wanted them to stop doing something or fly. 

The speech bubble* is a way to show words spoken by characters in comics* or cartoons. The birth of the speech bubble was in the seventeenth century in England. Since then, it has been used together with drawn characters. At that time, cartoonists used the speech bubble sometimes. A cartoon called Hogan's Alley began to use it all the time in 1895. In Japan, they still had to wait until the 1930s to have the speech bubble. 

A speech bubble usually has two parts – the bubble and the tail. The bubble has the messages that the character wants to express. The tail helps tell who has spoken the words. So the tail is always pointed to the character. If a character can't be seen in the picture, the tail may be pointed towards the bubble itself.

There are diverse speech bubbles. One of the most common bubbles is the thought bubble. It usually shows what the character is thinking about or an idea in a cloud-shaped or square bubble. How about expressing strong feelings? The jagged edge bubble can help to show anger or excitement. But when you want to make your character express a secret or just whisper some words, a bubble with dashed lines may be the best choice. One of the funniest bubbles is the wavy bubble with a wavy tail. It sends readers the message that the character is so tired.

The speech bubble is necessary for expressing spoken dialogues. Comic artists must carefully choose and place it in order to express the proper meaning and not to puzzle the reader. The proper use helps bring characters on the paper to life, for they have a "voice".
