There are many kinds of trees. All trees have roots. The roots hold trees in the ground. The roots soak up ( 吸收 ) water and food. Then trees get water and food from the roots. You can't see inside a tree. But you can study how water moves through trees.

    First, get a stalk ( 茎 ) of celery ( 芹菜 ) and cut off its end. Put red colour in a cup of water. Then put the stalk of the celery into the red water. Then we can see the red water moving up in the celery easily.

    After half an hour, take the celery out. Cut it in half. Your celery should be red. This is because the water moved up the stalk. Water moves through trees in the same way as it moved through the celery.

    The Duanwu Festival in China, also called Dragon Boat Festival, is celebrated on the fifth day of the fifth month every year according to the Chinese lunar calendar. For thousands of years, this festival has been marked by people's eating Zongzi and racing dragon boats. (A) To hold the dragon boat races is in memory of Qu Yuan. He was one of the greatest poets in ancient China.

    Qu Yuan was born in Zigui of Hubei Province over 2,200 years ago. Qu Yuan was an honest minister (大臣) of the State of Chu during the Warring States Period (475—22l BC) . He was upright, patriotic (爱国的) and wise. (B) 屈原想给自己的祖国带来和平并让它变得更强大。But the country was in the hands of bad officials, he could do nothing to change it. (C) He was very discouraged. At last, Qu Yuan ended his life by throwing himself into the Miluo River. It is said that people tried to save him by jumping into the river. But it was too late and all their efforts were in vain. Also, they were so sad and they threw rice into the water to feed Qu Yuan's spirit.

    Now we read his poem Li Sao which is filled with deep love for his country. We can see the dragon boat races and have a kind of Chinese food named Zongzi to eat during the Dragon boat Festival.

    Vienna is a beautiful old city on the River Danube in the center of Europe. It's the capital city of Austria and the center of European classical music. In the 18th century a lot of musicians came to study and work in Vienna.

    In the Strauss family, there were two composers called Johann Strauss: the father and the son. The father, Johann Strauss the elder, wrote and played music for traditional dances, called the waltz. His dance music made him famous all over Europe. The son, Johann Strauss the younger, was also very successful and popular. He wrote over 150 waltzes. In 1867 he wrote The Blue Danube waltz.

    Mozart was another very important composer. He was born in Austria in 1756. Before he was six, he played not only the piano but also the violin. His family took him around Europe and he gave concerts in many cities. He wrote hundreds of wonderful pieces of music. But he became very poor and died in 1791 when he was only 35. Like Johann Strauss, father and son, he was a great European musician, and many people still think his music is perfect.
