    I was a single parent of four small children, working at a low-paid job. Money was always tight, but we had a 1 over our heads, food on the table, clothes on our backs, and if not a lot, always 2. Not knowing we were poor, my kids(孩子们) just thought I was 3. I've always been glad about that.

    It was Christmas time, and although there wasn't 4 for a lot of gifts, we planned to celebrate with a family party. But the big 5 for the kids was the fun of Christmas 6.

    They planned weeks ahead of time, asking 7 what they wanted for Christmas. Fortunately, I had saved $120 for 8 to share by all five of us.

    The big 9 arrived. I gave each kid a twenty-dollar bill and 10 them to look for gifts of about four dollars each. Then everyone scattered(散开). We had two hours to shop; then we would 11 back at the “Santa's Workshop”.

    Driving home, everyone was in high Christmas spirits, 12 my younger daughter, Ginger, who was unusually 13. She had only one small, flat bag with a few candies—fifty-cent candies! I was so angry, but I didn't say anything 14 we got home. I called her into my bedroom and closed the door,15 to be angry again. This is what she told me.

     “I was looking 16 thinking of what to buy, and I 17 to read the little cards on the ‘Giving Trees.' One was for a little girl, four years old, and all she 18 for Christmas was a doll. So I took the card off the tree and 19 the doll for her. We have so much and she doesn't have anything.”

    I never felt so 20 as I did that day.

    In 1841, a book was published which astonished the world. It was called “Incidents of Travel in Central America, Chiapas and Yucatan”. The author John Loud Stephens had just returned from a long, difficult and dangerous journey through the thick rain forest of southern Mexico and Guatemala. He had once been there with Frederick Catherwood, an architect and artist, to search for the remains of a lost civilization known as the Mayas(玛雅). Very little was known about the Mayas at that time, but Catherwood's drawing in the book showed incredible cities with temples, pyramids and other buildings as impressive as those of their northern neighbors, the Aztecs. These cities, however, were deserted. The inhabitants(居民) had disappeared almost a thousand years before.

    Since that time, far more has been learned about this remarkable civilization. The Mayas had a highly-developed system of government and of agriculture, as well as an incredibly accurate system of measuring time. They were also wonderful engineers capable of moving huge blocks stone long distances and cutting them to accurate shapes and sizes.

    And yet although the Mayas knew about the wheel, they never used it. Neither did they use metals other than copper. What is ever more surprising is that they suddenly abandoned many of their cities and built new ones in the jungle. Some time around AD 900, Mayan civilization collapsed(崩溃). By the year 1200, their last great capital, Chichen Itza, was deserted.

    Who were these strange people and the even stranger gods they worshipped? What brought about their sudden and mysterious collapse? Some writers have tried to prove that the Mayas had contact with visitors from space and even that they themselves came from another planet. Some people believe that their civilization came to an end because the Mayas never developed a proper resistance to local germs and diseases. All we really know is that when the first Europeans appeared off their coast in 1517, this great and mysterious culture was only a memory.

    Time flies! This is a third year that I have been in this school. In the past two and a half years, our school had organized many activities. What impressed me best was an activity called “Learning to Farm”. In an autumn afternoon, we were sent to a farm which we learned to plant potatoes. Having been in the city for so a long time, we were so happy to go to the countryside. After divided into three groups, we started to work. Some students cut potatoes into pieces; some dug holes, and the others put the pieces of potatoes into the hole, put the earth back and push them down hard. We continued doing that until all the work was done. Although we were exhausted, but we felt fulfilled on our way back home.

    Food safety is a problem in all places around the world and people in different areas of the world prepare foods in different ways. The WHO released five simple rules for preparing food in a safe way. They call these rules the “Five Keys to Safer Food”.

    Key 1: Keep clean.

    People should wash their hands often — before touching food and while they are preparing food. People should wash all surfaces and equipment used for preparing food.

    Key 2: Separate raw and cooked.

    Raw foods should not touch prepared foods.

    Key 3:

    People should cook eggs and meat especially carefully. These foods may carry more micro-organisms (微生物) than other foods. Food like soup must be boiled for at least a minute to make it be cooked completely. It is also important that people re-heat cooked food completely.

    Key 4: Keep food at safe temperatures.

    When people finish eating, they should keep the left food in a refrigerator below 5℃and shouldn't store it for too long. At room temperature, about 20℃, the amount of micro-organisms can increase very quickly. But temperatures above 60℃ or below 5℃ control the growth of micro-organisms.

    Key 5: Use safe water and raw materials.

     Damaged or old food may develop harmful chemicals as it gets older.

A. Cook completely.

B. This key tells about the importance of washing.

C. Eat healthily.

D. They can live where we make food.

E. People should use safe water and choose fresh foods.

F. They cannot grow as quickly in a very hot or very cold environment.

G. People should use separate equipment and tools for touching and preparing raw foods.

    The ancient city of Xi'an in China holds many treasures. And last month, archaeologists working there made an important discovery—a buried palace built in the third century B.C. to honor China's first emperor.

    The entire palace measures roughly 2,260 feet long by 820 feet wide. It includes 10 courtyard houses and one main building. Archaeologists found bricks and pieces of pottery at the site of the palace, as well as the remains of walls and roads.

    The palace is part of the massive burial complex of Emperor Qin Shihuangdi. He conquered seven warring kingdoms and united ancient China in 211 B.C.

    Qin Shihuangdi wanted his legacy, or accomplishments, to be remembered forever. So he hired more than 700,000 workers to build his funeral complex in Xi'an. It represents a miniature version of his vast kingdom.

    The complex also includes the world-famous terra-cotta army, a collection of more than 8,000 life-size clay statues. These sculptures represent soldiers, acrobats, and horses from the Qin Dynasty (221 B.C.-206 B.C.). Scientists have not yet found all these terra-cotta warriors, even though they discovered more of the statues last summer.

    Farmers discovered the complex by accident in 1974. Since then, scientists studying the site have learned a great deal about life in ancient China. But much of the emperor's tomb has yet to be dug up, or unearthed. Many of the artifacts (objects from the past) are so old that scientists cannot preserve them.

    "Archaeologists fully acknowledge that nobody in the world has the technology (to safely dig up Xi'an's treasures) yet," explains Kristin Romey, an expert on Chinese archaeology.

    But as technology improves, archaeologists will keep digging to uncover the rest of the wonders that still lie buried in Xi'an.

    "It's one of the most important archaeological discoveries that's waiting to be made," says Romey, "and we know where it is."
