On a rainy day, about 150 volunteers worked for eight hours to clean up Carson Creek that is near a river. About nine tons of trash(H l)was taken out from there.

    "We did a good job, "said Alan Specter, the organizer of the event, "Were planning to come back here one more time, three years from now, Of course, we hope that there won't be so much trash next time."

    The trash came in all shapes, sizes, and colors: bottles, bicycles, batteries, furniture, clothing, plastic bags, dolls, and even a golf bag with a full set of golf clubs(球杆).

    The dirty and tiring work was done by two volunteer groups Save the Bay and Watch the Whales. Most of the volunteers came from a local police station and a fire station. And some of them were old people who had already retired (退休)。

    That day, it rained a little. All of them wore boots, gloves and raincoats. The work took place along a two- mile river with over 500 big yellow trash bags every where.

    No one found anything that cost much. A five- year-old boy found an earring which he thought might be worth a million dollars. He said he'd sell it. Then he'd donate half of the money to Watch the Whales, and use the other half to buy his favorite ice- cream every day.

    Many people laughed at the boy's story. However, it was easily found that the environment there did become better.

There are lots of great people at home and abroad. Madame Curie was one of them. 

Among all the pen productions, the writing brush（maobi）is a kind of special writing tool mainly made in China. 

Archaeologists（考古学家）said that writing brushes first appeared about 5, 000 years ago. Hengshui, Xuancheng and Huzhou were three centers for making writing brushes in Chinese history. Many people still celebrate the invention of the brush every year. 

____ Materials for the head part include rabbit hair, horse hair and so on. Some Chinese people like to make the writing brush with babies' lanugos（胎毛）. People believe that a writing brush made of the hair of newborn habies will bring good luck while taking exams. As for stalks（笔杆）, normal materials are usually wood, but we can also see some special ones made of ivory, gold and some other expensive materials. 

It's considered that the writing brush is the most important one among the Four Treasures of Chinese Study. In Chinese calligraphy（书法）and Chinese painting, the writing brush is widely used. In ancient China, children had to learn calligraphy and try to write a good hand. Even the emperors were good at calligraphy. Nowadays, some Chinese people still practice calligraphy with a writing brush from a very young age. Calligraphy is beneficial to people in some ways. When writing, people will forget all worries and even themselves, turning all thoughts into the beauty of art. People think it helps improve a person's temper（脾气）. 

Writing or painting with writing brushes is not only a way of communication, but also a way of expressing a person's inner world. 

Hello, everyone. My name's John. Here is the picture of my family tree. Let's have a look. 

People are always curious to know what things on the earth can be seen from space. Some of geographical features (地势) and man- made things are huge enough to be seen from hundreds of kilometres above. Here we list some huge things on the earth that can be seen from space. 

●Great Barrier Reef

The Great Barrier Reef which is more than 2, 000 kilometres long becomes the largest coral reef on the earth. It also becomes the largest living thing in this world that can be seen from space. The Great Barrier Reef connects more than 900 reef islands, lied in the eastern part of Australia. It is a home for about 1, 500 tropical(热带的) fish species. It also becomes the main place of divers and the finest tourist place in Australia. 

● Pyramids of Giza

One of the seven wonders of ancient world also becomes a favourite place for astronomers to take photos from space. It cannot be seen at all by eyes, so astronomers used a special camera for it. Within space images of Pyramids of Giza, the Great Sphin x which has a face of human but a body of lion can also be seen from space under possible conditions. 

●Himalayas

Himalayas, including the world's highest mountains, can be seen from space. Himalayas have more than 110 peaks rising to elevations of 24, 000 feet(7, 300 metres) or more above sea level. The width of Himalayas from south to north varies between 125 and 250 miles(200 and 400 km). Their total area amounts are about 230, 000 square miles(595, 000 square km).
