    ①Some people like to be scared! Choosing to be scared can be fun. Dr. Margee Kerr, a sociologist, explained the science of fear. "Some people like to be scared because they like the way their body changes." she says.

    ②Being scared is not always fun. When a balloon pops, we may jump. Our heart beats faster and harder. How does the body have the reactions?" When we meet something startling, our brain and body start making changes to help prepare us for the unknown." Dr. Kerr explains, "These changes are caused by the senses（感官）, which always send information to the brain. It gives out chemicals into the bloodstream, and those chemicals act on different parts of the body. At the same time, the brain decides whether or not the danger is real."

    ③Fear is a tool that the brain uses to keep the body safe. It helps a person to hide, run away, or protect oneself. Our memories also help protect us. As we grow, we learn what's unsafe, and our brains keep those memories. Then our brains use fear to warn us of dangers. Dr.Kerr says, "_______________________________. "

    ④However, too much fear can be harmful because experiences can lead to long-lasting fears that may stop a person from trying new things. A long-lasting fear can mean you've had a bad experience, and your brain doesn't want you to have it again.

    ⑤Many people have beaten their own fears. Instead of listening to their imagination, they learn the facts about anything that seems scary. Knowledge can help a person feel less afraid. Dr. Kerr grew up on a farm. She was scared of black bears in the woods before. She says," After I read a lot about them, I knew for sure what to do if I ever met a bear and how to protect myself."

In winter, some people burn(煤) to keep warm.

In this life, what did you miss?

The wife asked the husband when she was 25. The husband worriedly replied, “I missed a good job.” When she was 35, the husband angrily told her that he had just missed the bus. At 45, the husband sadly said, “I missed the last momentsaying goodbye to my grandfather before his last breath.” At 55, the husband said disappointingly, “I missed a good chance to retire (退休). At 65, the husband hurriedly replied, “I missed the time for a dentist.”

At 75, the wife did not ask the husband anymore. The husband was in front of the very sick wife with his knees down. Remembering the question the wife used to ask him, this time he asked the wife the same question. The wife, with a smile and peaceful look, replied, “In this life, I did not miss having you!”

The husband was full of tears. He always thought that they could be together forever. He was always busy with work and personal things. So much so he had never thought about her. The husband hugged the wife and said, “Over 50 years, how I had allowed myself to be so blind to your love and care for me.”

In the busy life, so many people fill all their lives with their jobs. These people spend all their time and health meeting the social expectations. They never spare time on health care. They miss the chances to be with their children in their growing up. They pay no attention to the loved ones who care for them, and also their health.

Nobody knows what is going to happen one year from now. Life is not long, so always live in the now. Express your thanks to your loved ones in words. Show your care with actions. Treat each day as the last day of life. In this way, when you are gone, you loved ones would have nothing to feel sorry about.

    A very important world problem is the growth of population on the earth. The population of the world today is more than 6,500,000,000. That is a great number and we know it quite well. ①The important thing is not how large the population of the world is now, but is the rate(速度) of the growth. It is about 1.63% every year after the number of dead people has been taken away.

    To give you some ideas of the birth rate, look at the ②second hand of your watch. Every second, four babies are born in the world. Another baby! Another baby! Another baby! Another baby! ③You can not speak quickly enough to keep up with the rate of the growth of the population. It is growing faster and faster. So it goes on, hour after hour. In one day, people have to find food for about 350,000 mouths more.

    This great growth of population will make a big problem by the year 2050 — there will be as many as 7,500,000,000 people on the earth! So this is one of the biggest problems that you are going to meet in your life.
