Every day, hundreds of children in Africa lose their young lives, because they have terrible diseases or don't have enough food to eat. Most African countries are poor.And many parents have no jobs, so they have little money to buy food or medicine. We hold the concert to raise money for the children in Africa.

For example, the Feed Africa Fund (援非基金)spends millions of dollars every year on food for them in Africa. All the money comes from kind and generous people, just like all of you.

Just one dollar can buy enough rice or corn to feed a family of four for three days.

Ten dollars? Twenty dollars? I am sure you can spend a little less on your own food so that you have a few dollars for the Feed Africa Fund.

Ladies and gentlemen, we now make a collection for the children in Africa. Please be generous. Thank you!

Lamu was a 12-year-old Tibetan girl. She wanted to go to Beijing to watch the 2008 Olympics. Only one month ago, Lamu still thought it would be difficult.

In the past Tibet had no railroad (铁路). If Lamu took a bus, it would take her a long time to reach Beijing. And a plane ticket would cost lots of money.

However, things changed for Lamu. She was able to buy a ticket to the world's highest railroad. The Qinghai-Tibet Railway had been completed! The 1,142-kilometer railroad runs on the Qinghai-Tibet plateau (高原). Lamu could reach Beijing by train in 48 hours!

About 550 kilometers of the railroad are constructed on the frozen earth (冻土). When the frozen earth warms in summer, it can move the track. But Chinese scientists have built a special structure to solve the problem. The Qinghai-Tibet Railway has been designed with the wild animals in the designers' minds. It also has special underpasses (地下通道) for animals like Tibetan antelopes (藏羚羊) to go through.

"The new railroad greatly helps Tibet's tourism," said Liu Yueqin, an expert at the Chinese Academy of Social Sciences (中国社科院).

As more tourists take trains to Tibet, there are more money for Tibetans. With the money, more kids can go to school.

The railroad also makes things less expensive in Tibet. Now one can buy a TV set for about 1,500 yuan. It used to be much higher than that price. When there was no railroad, it had been difficult to send things in and out of Tibet. With the new railroad, shopping can be more convenient (方便的) and faster.

One day Peng Xianzhe learned he would go to the Mashan School in Guizhou. The 16-year-old boy tried to imagine how serious the drought was for the students at that school. However, he realized it was more serious than he had imagined when he saw the sign "DON'T wash clothes with water，or you will be punished（惩罚）. "

Because of drought, the school has been short of water for a long time. Each student has only one bottle of water every day for washing and drinking. The drought has made the poor students much poorer.

Peng is a student from Beijing Chaoyang Foreign Language School. He took part in the school's Rain & Bow Project from April 2 to 10.

The project idea came from Peng's principal（负责人）. One day, she heard a sad story about Li Guoxian, a poor girl in the Mashan School，who stopped going to school because of drought. The principal started this project to help the school. In one day, 3，000 students made over 10，000 donations of water，books and clothes.

Peng and other four students went to the Mashan School and gave the donations with five teachers. They visited poor families, made surveys and had classes at the school.

Ding Zhentao，16，was worried about the school's poor learning environment. "The blackboards and playground are too shabby to use，"Ding said. "Besides, there really aren't enough teachers. A teacher has to teach both history and English, and even the cook is a class teacher. "

Although life isn't easy, students at the school have a positive attitude(积极的态度）towards life and they are quite willing to learn. That's what moved 16-year-old Chen Shi most.

"They sang their songs together as usual before class every afternoon. After class, the students asked us to tell them things about Beijing and our studies," Chen said. "You can see the passion(热情）in them. I believe it will make a difference. Their futures will be bright. "

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. The 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 second hand of your watch. Every second, four babies are born in the world. Another baby! Another baby! Another baby! Another baby! You can not speak quickly enough to keep up with the birth rate. The population is growing faster and faster. So it goes on, hour after hour. In one day, people have to find food for over 350,000 mouths more.

This great growth of population will make a big problem by the year 2010—there will be as many as 7,000,000,000 people on the earth! So this is one of the biggest problems that you are going to meet within your life.
