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.

Has your mother or grandmother ever made embroidered (刺绣的)clothes for you? In the past, Chinese people often embroidered on hats, shoes and dresses. Some girls would even embroider on a sachet (香囊)as a gift for their lovers.

Shu embroidery comes from Sichuan. It is said that Shu embroidery is the old lest kind of embroidery in China. People began to make it during the Han Dynasty (206BC-220AD).They sold it to other countries such as ancient Rome.

Shu embroidery takes time. It might take as long as a whole day to finish just 10 cm. Embroidery workers need to divide each silk thread (丝线) into more than 10 or over 30 smaller threads. Each smaller thread is thinner than a human hair.

Meng Dezhi, who used to work at the Chengdu Shu Embroidery Factory，has been making Shu embroidery for over 40 years. She loves this form of art and wants more people to try it, so she gives lessons in universities. She said. "Although the work is hard, Shu embroidery stands for thousands of years of Sichuan culture. It is a symbol of Chinese culture as well."

Look at the picture! You can {#blank#}1{#/blank#} some school things(学习用品) in it, some {#blank#}2{#/blank#} and pencils, two erasers and two dictionaries. The blue eraser is {#blank#}3{#/blank#}. Itˈs big. The green eraser is Lucyˈs. She is my good {#blank#}4{#/blank#}. We are in the same(相同的) school. This is my English dictionary. What {#blank#}5{#/blank#} the Chinese {#blank#}6{#/blank#}? Oh, itˈs Lucyˈs. My English {#blank#}7{#/blank#} is Mr. Brown. {#blank#}8{#/blank#} first name is Bill. He is a good teacher. We thank him(他) {#blank#}9{#/blank#} his {#blank#}10{#/blank#}.

In the eyes of many foreigners, Chinese are the best hosts and the worst guests in the world. They're not really bad guests but because the guest-host relationship in China is much different than in some Western countries it appears they are not nice guests. And Western guests sometimes look rude in the eyes of Chinese guests.  

　　In China guests are almost like gods. Whenever I enter a Chinese person's home there is always fruit on the table for me and someone is quick to bring me a cup of tea or water. In the West generally the guest is not a god. Acting according to the host's way of doing things is usual behaviour for a guest. 

　　My wife's mother is a very kind elderly Chinese lady who doesn't smoke. When I see some of her guests smoking in her house, as a non-smoker I feel unhappy. Usually I want to stop them directly but I must realize that she must not do that. In most North America homes if you are a guest and the hosts are not smokers, you should not smoke in their house. At the very least you could ask "Is it OK if I smoke?" But don't be surprised if they say "No, you can't smoke." In our culture if you smoke in their home you are a bad guest, but if they don't allow you to smoke in their house they are not a rude guest.

　　Guests in China also have special habits. Some Western people may not adapt to these habits very soon. Thankfully my wife is Chinese so whenever we visit a Chinese family she tells me to buy them a gift. However giving a gift to a host is not always necessary in my country. So if you invite international guests to your home don't be too surprised if they don't bring you a gift. 

　　In China you probably won't need to change the guest-host relationship very much because you will probably only be the host and Chinese are naturally very good hosts. If Western hosts invite you to their house, try not to be too surprised if their style of treating you is not what you have expected.
