    There is little rain in desert. Because deserts are so dry, they have no ¡°quilt¡± to help stop the soil from going away. As a result, they may get very hot during the day with the sun shining, but don¡¯t hold the heat overnight. Many deserts can quickly get cold once the sun goes down. Some deserts can reach temperatures of over 100 degrees F during the day and then drop below freezing (32 degrees F) during the night.

    The largest hot and dry desert in the world is the Sahara Desert in Northern Africa. The Sahara is a sandy desert with great sand hills. It covers over 3 million square miles of Africa. Other large deserts include the Arabian Desert in the Middle East, the Gobi Desert in Northern China and Mongolia, and Kalahari Desert in Africa.

    Animals that live in the desert are also used to needing little water. Many get all the water they need from the food they eat. Other animals keep water that they can use later. The camel stores up fat in its hump while other animals keep something they need in their tails.

    Only certain types of plants can live in the terrible environment of the desert. You won¡¯t see a lot of tall trees in the desert. Most plants have a way to keep water in their leaves, or trunks so they can live a long time without water.

    Now deserts cover around 20% of the world¡¯s land, but they are growing. This is called desertification and is caused by different reasons including human activities. The Sahara Desert is growing larger and larger each year. What should we do with it ?

    On September 19, Alibaba went public (ÉÏÊÐ) on the New York Shock Exchange. It shows that Ma Yun has done his business successfully. A short Chinese man seems to be the tallest man in the world right now. Ma used to be an English teacher. So far, he has become the richest man on the Chinese mainland.

    Ma was born in Hangzhou and grew up as a happy kid. At the age of twelve, he found that English was very interesting. Every morning he got up at 5 a.m., and then ran to a hotel near the West Lake where he could communicate with foreign tourists in English. He did it for nine years.The experience made him become a fantastic English speaker and also opened his eyes to the wide world. In a 1995 trip to the US, Ma was shown to the Internet for the first time. Seeing the chance, Ma returned to China and set up a website without knowing much about computers. Four years later, Ma set up Alibaba in Hangzhou. People called him ¡°Crazy Jack Ma¡±. But fifteen years later, Alibaba has developed into the world¡¯s largest e-commerce (µç×ÓÉÌÎñ) company.

    I came to study in the US last fall. My life was quite simple when I arrived at Andover. Although I had quite a few after-class activities, I didn¡¯t take any official leadership position.

    This changed when I received an email from Ms Griffith, my cluster dean (ËÞÉáÂ¥Ö÷ÈÎ), that a new female DC Rep was needed. DC Rep Discipline Committee Representative. students living in school break serious rules, like taking drugs, getting drunk or cheating in their studies. Such students must be punished£¨³Í·££©. The punishments are by a DC Rep, two student representatives£¨´ú±í£© and the cluster dean. I was really interested in becoming DC Rep for my cluster, Pine Knoll, so were five other students. We had to hold an election and Ms Griffith asked us to write to be sent to everyone in Pine Knoll.

    I thought hard about what to . I didn¡¯t want to make any promises, because they are difficult to keep. I didn¡¯t want to say I was experienced, because I was not. So I started my speech by explaining I wanted to become DC Rep. ¡°I want to serve Pine Knoll.¡± I wrote .

    I made three posters that said ¡°Vote For Teresa¡± and put them on every exit of my cluster so that people would my name when they went to vote.

    Although I tried hard, I didn¡¯t win the election£¨Ñ¡¾Ù£©. I was disappointed, but my positive nature did not allow me to for very long. I actually when my friends tried to comfort me. ¡°Teresa, I am sorry that you didn¡¯t win the election,¡± they would say.

    ¡°No, don¡¯t be sorry for me. I am very happy to have taken part in the election,¡± I said.

    It is true that the process is much more important than the . I am surprised and happy to discover my hidden .
