What problems do the teenagers probably have? Here is a survey showing their main problems.

When she was little, Gladys Kalema liked to stay with dogs and cats at home. She wanted to work with animals when she grew up. This dream came true when Kalema was in her early twenties. She became a wildlife doctor in Africa.

That was thirty years ago. Since then, Kalema has never stopped caring for wild animals. She does her best to save the mountain gorilla (大猩猩). This animal is in great danger. But she doesn’t just protect the animals. She also tries her best to help the local communities.

Many local people lived a poor life. Some of them made money by catching wild animals. Kalema wanted to protect these animals. The key to doing it, she realized, was to make the local people’s life better. The woman provided these people with fast-growing crops (庄稼). By growing the crops, the locals could feed themselves and make a better living. They no longer needed to capture animals. Slowly, their thought towards these wild animals began to change. Now, many of them have become animal protectors.

Last year, Kalema received the highest environmental prize from the United Nations because of her actions.

Music is different from songs. Songs express feelings with lyrics, but music with tones (音调). Unlike songs, music tones in themselves have no specific meanings. Different people may get different things from the same musical performance. Though some music works are difficult to understand, people need music in their daily life because it brings fun to them. Different people like different music: some love classical music, and others take pleasure in pop music. Most young people like pop music.

Pop music began in the USA and became popular around the world during the 1950s and 60s. The best-known early type of pop music was “rock and roll”. Pop music has taken the place of native music in many parts of the world. It has caused the number of people for “jazz” music to become much smaller than in the 1950s and earlier and it has now begun to become the most popular. Much pop music is without artistic (艺术的) value, but the works of some pop singers such as the Beatles, Bob Dylan, the groups like Pink Floyd and Crosby are excellent. And there is still great interest in it today. Pop music concerts and festivals are held all over the world.

Every culture around the world has different customs and ways of communicating. When you learn a language, you learn more than words.

In China, people are used to saying “sorry” to show that they regret doing something wrong. But it’s very proud for American people to have polite manners towards one another in public. They often use the word “sorry” —even when they don’t really mean it! Usually, if they want to ask a stranger for the time, they will start by saying “Sorry to trouble you.” If they’re five minutes late for the appointment, they will greet the person by saying “Sorry, I’m late!” It’s quite different in China. They use the word “sorry” in so many different situations that the meaning of the word has changed a little over time. The two main dictionary definitions (定义) of “sorry” are: 1) feeling sad for someone else because of their problems or bad luck; 2) feeling regret because you’ve done something wrong.

So what does “sorry” really mean? And why do western people use it so much? Well, in western culture, saying “sorry” is a way to be polite. It’s also a very clever way to get what they want. If you want to borrow something from others, you’d better say “sorry” to them about something. Or it’s hard for you to get what you want. So maybe saying “sorry” is not only just being polite, but also a good method to get what you want!
