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.

①Animals are important and they are our friends. But some of them are in danger now. What can we do to help save them?

②Don't eat meat. Some of us like to eat meat because it is delicious. But do you know some meat comes from endangered(濒危的) animals? To save animals, please choose more vegetables and fruit to eat instead of meat. And it's healthy for us, too. 

③Don't wear clothes made of fur(皮毛). Sometimes people also kill animals for fur. But if we don't buy or wear clothes made of fur, people will no longer kill them. 

④Donate(捐赠) money to Animal Helper(AH). AH always does everything to help save animals. But it is often short of money. So please save some money and give it away to AH to help animals. 

⑤Tell people it's important to save animals. Not all people are aware of their importance to humans and why we must save them. So why not tell people around us that it's important to save animals? It's helpful.

Joel Griffin is a famous expert of dinosaurs （恐龙）. An interviewer from The world is getting some information from Mr. Griffin. 

{#blank#}1{#/blank#}

They lived millions of years ago and their bones （骨头） have turned to stone. They tell us what the world was like millions of years ago. Scientists slowly put together what they discovered. The first dinosaur bones were discovered in 1818. 

{#blank#}2{#/blank#}

When dinosaurs were alive，the earth was a very different place. The weather was much warmer and the land was covered with forests. There were no animals，such as cows or horses，like the ones we know today. 

{#blank#}3{#/blank#}

There were thousands of different kinds of dinosaurs. Of course there were some huge dinosaurs. They were the biggest animals that have ever lived. But some were very small. Some dinosaurs had heavy bodies and walked on all four legs. Others walked on two strong back legs and had two short front ones. 

{#blank#}4{#/blank#}

Some dinosaurs only fed on plants. They were often heavy，slow﹣moving. Many of them spent a lot of time in water. It prevented their enemies from attacking them. Other dinosaurs were meat﹣eaters. They hunted for their food. These dinosaurs were fighters with sharp teeth. 

{#blank#}5{#/blank#}

Many of the plants that the dinosaurs needed to eat disappeared. Some scientists believe that the weather changed from warm to cold. Some scientists believe that dinosaurs were not able to get used to the changes in the environment. They did not like the cold weather and they could not find enough to eat.
