Dear ladies and gentlemen,

I'm here to make a speech on building a green home. Our city Guangzhou has become more and more beautiful than before. However, there are many things we can do to protect the environment and build a green home. First of all, we ignore the garbage classification and put the garbage directly into the dustbin. Wherever we go, we should throw rubbish into right dustbins to keep our home clean and tidy. Secondly, the air pollution is a serious problem, too. I call on you and your parents to take the bus more and driving less. Lastly, we should plant as many trees as possible to protect our home¡¯s natural environment instead of cutting trees.

If we make a contribution to building a green home, our home will become a better place to live in.

That's all. Thanks a lot for your attention.

Chinese writing is one of the world¡¯s greatest writing systems. It is more w¡¾1¡¿ in use than alphabetic (×ÖĸµÄ) writing systems. More than half of the world¡¯s books are written in Chinese, including historical writings and novels, along with writings on government and law.

At the beginning, written Chinese was a picture-based l¡¾2¡¿. It dates back several thousand years to the u¡¾3¡¿ of animal bones and shells on which symbols were carved (¿Ì) by ancient Chinese people. Some of the ancient symbols can still be seen in t¡¾4¡¿ hanzi.

By the Shang Dynasty, these symbols had become a well-developed writing system. Over the years, the system developed into different forms, as it was a time when people were d¡¾5¡¿ geographically, leading to different dialects (·½ÑÔ) and characters. This, however, c¡¾6¡¿ under Emperor Qinshihuang of the Qin Dynasty.

Emperor Qinshihuang united (ͳһ) the seven major states into one country where the Chinese writing system began to develop in one direction. That writing system was of great i¡¾7¡¿ in uniting the Chinese people and culture. Even today, no matter where Chinese people live or what dialect they speak, they can all still c¡¾8¡¿ in writing. Written Chinese has also become an important method to c¡¾9¡¿ China¡¯s present with its past. People in modern times can read the classic works which were written by Chinese in ancient times.

Today, Chinese writing system is still an important part of Chinese culture. As China plays a g¡¾10¡¿ role in the world, an increasing number of international students are beginning to appreciate (ÐÀÉÍ) China¡¯s culture through this amazing language. Written Chinese spreads Chinese culture wherever it goes.
