[EX Q]: Article: Chinese New Year Celebration is the most important celebration of the year. Chinese people may celebrate the Chinese New Year in slightly different ways but their wishes are almost the same; they want their family members and friends to be healthy and lucky during next year. Chinese New Year Celebration usually lasts for 15 days. Celebratory activities include Chinese New Feast, firecrackers, giving lucky money to children, the New Year bell ringing and Chinese New Year Greetings. Most of Chinese people will stop the celebrating in their home on the 7th day of New Year because the national holiday usually ends around that day, however celebrations in public areas can last until the 15th day of New Year. It is the money given to kids from their parents and grandparents as New Year gift. The money is believed to bring good luck, ward off monsters; hence the name "lucky money". Parents and grandparents first put money in small, especially-made red envelopes and give the red envelopes to their kids after the New Year's Feast or when they come to visit them on the New Year. They choose to put the money in red envelopes because Chinese people think red is a lucky color. They want to give their children both lucky money and lucky color.

[EX Q]: Article: A great-grandfather has put up his Christmas tree for the 85thtime after his father first bought it from a toy shop. Douglas Hewitt, 85, has celebrated every Christmas with the artificial tree since he was born. His father bought the tree from a toy shop in Sheffield just months after Douglas was born. The four-foot tree remains the centre point of the Hewitt family household during every festive season. Mr. Hewitt, of South Anston, South Yorkshire, said, "It reminds us of my childhood, our children's childhood and our grandchildren and great-grandchildren's after that. They all come and look at it and smile; it's become part of the furniture. If we didn't put that Christmas tree up, it wouldn't feel like Christmas." The tree was passed down to Mr. Hewitt when he married Mavis. Mrs. Hewitt said, "Year after year we have just carried on using that one. You have to be a bit more careful with it now, as it's _ ." Their daughter, June Murphy, also has fond memories of the Christmas tree. She said, "It was in my grandparents' home and then it was given to us. It looks a little thin now, as each time you get it out something else falls off. It's become a bit of a family joke. Each year someone has to comment 'not again!' But it's a Christmas tradition of getting the tree out that we all love. We'd all be sad to see it go, as I think it would be hard to find such a loved replacement." Mr. Hewitt said, "There were a lot more branches on it, and it's lost its feathers that were all along the edge. There were little candle holders on the ends and little legs on it, but unfortunately they've been lost over the years."
Question: Where did Douglas Hewitt get the Christmas tree?
Options: (A) He got it from his father. (B) He bought it from a toy shop. (C) He made it by himself. (D) He cut it down in a forest.

[EX Q]: Article: Archaeology, like many academic words, comes from Greek and means, more or less, "the study of old things". So, it is really a part of the study of history. However, most historians use paper evidence, such as letters, paintings and photographs, but archaeologists learn from the objects left behind by the humans of long ago. Normally, _ are the hard materials that don't break down or disappear very quickly--things like human bones and objects made from stone and metal. It is very unusual to find anything more than the hard evidence of history--normally, the bacteria in the air eat away at soft materials, like bodies, clothes and things made of wood. Occasionally, things are different. In 1984, two men made an amazing discovery while working in a bog called Lindow Moss, in the north of England. A bog is a very wet area of earth, with a lot of plants growing in it. It can be like a very big and very thick vegetable soup--walk in the wrong place and you can sink and disappear forever. The men were working when one of them saw something sticking out--a human foot! Naturally, the men called the police, who then found the rest of the body. Was it a case of murder? Possibly--but it was a death nearly two thousand years old. The two men had found a body from the time of the Roman invasion of Britain. Despite being so old, this body had skin, muscles, hair and internal organs--the scientists who examined him were able to look inside the man's stomach and find the food that he had eaten for his last meal! Why was this man so well preserved? It was because he was in a very watery environment, safe from the bacteria that need oxygen to live. Also, the water in the bog was very acidic. The acid preserved the man's skin in the way that animal skin is preserved for leather coats and shoes. How did he die? Understandably, archaeologists and other scientists wanted to know more about the person that they called "Lindow Man". His hands and fingernails suggested that he hadn't done heavy manual work in his life--he could have been a rich man. They found that he hadn't died by accident. The archaeologists believe that he was sacrificed to three different gods.
Question: Which of the following helped to preserve "Lindow Man"?
Options: (A) Ice and low temperature (B) Acid and water (C) Soil and energy (D) Bacteria and oxygen
