It is natural that children are curious (好奇的) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.

It's going to be a chaotic(混乱的)day. How do I know? It’s Monday. OK, joking. But, I do predict that today will be filled with the normal last-minute tasks, fire drills, and unforeseen events. So, how do you keep yourself from being swept away in the stream of chaos? How do you remain calm while others are rushing and panicking? There's a problem… Panic! When things don't go as planned, how do you react? Are you the calm one who works to fix things? Or the one running around like Chicken Little screaming that the sky falling? Getting upset or alarmed can seem like natural reactions to a problem.
Here are a few tips to kelp you remain calm in the face of the storm:
? Don't Panic? You are better able to find a solution if you????????????? aren't panicking. If you can keep your head when others are losing theirs, you will be able to make a dear decision in the chaos.
? There Aren't Many True Emergenaes ? My time as a Naval Officer taught me about true emergencies. In the military, when there is a problem, people can get hurt or die. This is not usually the case when the office copier or email server goes down. Keep things in perspective. There are very few true emergencies in life.
? Avoid the "Fight or Flight" ? When you are stressed, your body will want to go into "fight or flight." Your body was designed to keep you safe from danger, but its natural reflexes aren't always the best solution against a project gone away. Keep your emotions in check and ensure that your physical reflexes don’t make bad decisions for you.
? Head Into The Problem??? While everyone else is running away, true leaders walk into a problem. Sticking your head in the sand only makes things worse. Instead of trying to ignore the situition, get to the heart of the issue as soon as possible. Only then can you address it
How Will You React? When you find yourself ready to lose it, take a step back. Ask, "In this truly an emergcncy?" Keep your head when others are losing theirs. And you'll find that you are that much closer to a solution.
