  Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy.

Some scientists believe that birds do sing some of the time just because they are happy.

However, they sing most of the time for a very different reason.   Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims as its own. . No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.

If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting season. So he is screaming all the time, whether he can see an outsider or not.   

Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs. You can see that birds have a language all their own.

An interview with a volunteer.

  ___________________

I am a member of our school’s volunteer association. During my freshman(大学一年级新生) year, I was asked to write up a plan for volunteers who assisted patients there. So I visited the hospice (末期病人疗养所) several times. Later, I realized I could do more for the patients and so began volunteering.

  ___________________

When I was a freshman, I was not used to college life. I sometimes felt the hospice was like home. Here, many grannies treated me like their own relative, and I could feel strongly that I was needed. Just shaking hands made them come to life. I not only get great comfort from helping many patients get through the last period of their lives. I also learn a lot from their experiences.

  ___________________

You have to be prepared both mentally and physically. Most people at this hospice are facing death. So you have prepared to be patient and make them happy and relaxed. Also, persistence is needed. After seeing so many people here die, I know that persistence is hard. But you have to remember that you job is to help them feel less pain before death.

   ___________________

Good volunteers have something in common: They regard their job as a career, rather than some task that’s been assigned. They learn to enjoy what they are doing, no matter how boring it is. We have a volunteer who has been with us for more than a year. His job is translating letters from kids we helped. Even when he was busy with his classes, he would take a taxi to our office to pick up the letters. When we asked him why, he told us he enjoyed the kids’ stories and learned a lot from them.

Students are often very enthusiastic and direct. They give us feedback that helps us improve our work. And they value the opportunity we give them to broaden their horizons. However, they are still young and some are not responsible enough. And sometimes, they are lazy and careless.

“You do not need to be a rocket scientist.” Americans hear these words often.

People say them in schools, offices and factories. Broadcasters on radio and television use them.

How did the expression begin? No one seems to know it. 66 “It grew,” he says, “because rocket scientists probably are the most intelligent people around.”

Not everyone would agree. Some people might be considered more intelligent than rocket scientists. For example, a person who speaks and reads fifteen languages, or a medical doctor who operates on the brain. Still, many people would agree that there is something special about scientists who build rockets. 67

Moving pictures from before World War II showed a man named Buck Rogers landing on the planet Mars. He was a hero who could withdraw any enemy from outer space. The rocket scientist is a different kind of hero. 68

Rocket scientists, however, can have problems just like everyone else. A Washington rocket scientist tells about a launch that was postponed many, many times. Finally, everything seemed right. Mechanical failures had been repaired. The weather was good. The scientists had planned that part of the rocket would fall into the ocean after the launch. All ships and boats within many kilometers of the danger area had been warned. But in the last few seconds a small boat entered the area. 69

70 One scientist said, "As a child I loved to build rockets. Now I am grown. I still love to build rockets. And now I get paid for it."

E. Have you ever heard of the space travel?

F. But an official of the American space agency, NASA, says the expression just grew.

G. Once again, the launch was put off.
