[Q]: Article: Every year, as Spring Festival draws near, most Chinese people will get excited to make preparation for the most important festival and make plan for the winter break. It is a little like Christmas in the United States, but there are some differences between the two festivals. Both the major Chinese and the major Western holidays come during the cold season, and special food is expected. In western countries, cookies and cakes begin just after Thanksgiving in November and show up everywhere. Turkey, potatoes and other food come later. Similar thing happens in China. Entering lunar December, most families will make shopping plans for _ and food is certainly one of the most important things to be considered. At the end of the month, both parents in each family will be very busy---the father is busy buying food while the mother is busy cooking. A deeper similarity is tradition. Christmas, as the letters "Christ" suggests, began as a holiday to celebrate the birthday of Jesus Christ. Many people pray on this day. In China, people living in cities or towns, though they don't plan to sow seeds this month, still celebrate on the big day for farmers. Followers of both holidays are also different from each other. While Chinese people travel to the homes of elder relatives, Americans usually call or send cards. Westerners prefer Christmas carols to fireworks. In Christmas, many family gifts come together instead of one by one, since adults may have only one day free to celebrate. But the most curious difference is about students. Chinese students going home for Spring Festival sometimes report that they get bored by the end of vacation, yet American students seldom get bored around Christmas and western New Year. Not everyone enjoys classic holiday traditions. Students in western countries may get upset, as too much homework, travel or bad family relations may destroy the short holiday season. In China, more and more college students choose to travel or work during the winter holiday instead of going home to stay with their families. It's against the tradition but many people accept it.
Question: What does the writer mainly want to tell us in this passage?
Options: (A) Food in different festivals. (B) Differences between two festivals. (C) Festivals in China and western countries. (D) Traditional celebrations in different countries.

[Q]: Article: Dear Textual Healing, I would be very interested in your recommendations for any books to help me through a difficult time of my life. At 57, I am feeling a bit lost. I have a wonderful, loving husband and bright, caring teenage daughter but I am lonely and have lost my spark for life. I have always taken care of everyone and managed a career, but, after the death of my father this summer, my difficulties as a child in a terribly abnormal family have come back to me regularly. I have become unfocused and often alone while my husband is away frequently on business and my daughter busy with school and friends. I am seeking the help of a therapist and taking care of myself but I would love to read something to help me "get my groove back" and reengage with life. PC Dear PC, From the letter you've given us about your life, it's no wonder you're feeling a little lost. But before prescribing titles to help you get your groove back, I'd recommend taking a journey into Rebecca Solnit's non-fiction book,A Field Guide to Getting Lost, which is packed with the wisdom of everyone from Pat Barker to Thoreau and Keats. The word lost is rooted in the Old Norse "los", meaning the disbanding of an army. "This origin suggests soldiers falling out of formation to go home, ceasing fighting with the wide world. I worry now that many people never disband their armies, never go beyond what they know," Solnit writes. So instead of fearing that lost feeling, try seeing its potential for discovery. Explorers, remember, are always lost simply because they're forever someplace new. "Leave the door open for the unknown, the door into the dark," Solnit advises. "That's where the most important things come from, where you yourself came from, and where you will go." For something that asks a little less of the reader while still giving plenty in return, try a dose (--) of Anne Tyler, the beloved creator of numerous heroes whose serious conditions will move anyone who finds themselves in a midlife difficult situation. One such character is 53-year-old Rebecca Davitch, the heroine ofBack When We Were Grownups. Like you, she's combined marriage and motherhood with a career but suddenly finds herself feeling lonely in her own home. Could it be, she wonders, that she's "turned into the wrong person"? Don't be fooled by the way this novel ambles along -- as Rebecca revisits youthful ambitions and the college boyfriend she abandoned, it asks some heart-rending questions before arriving at a place of graceful, joyous acceptance. Along similar lines, I'm also going to recommendThe Unlikely Pilgrimage of Harold Fryby Rachel Joyce. Its hero is 65 when he learns that a former colleague sick. On his way to post her a note,he decides instead to visit her -- on foot, from his home in deepest Devon to England's northernmost town, more than 600 miles away. You don't manage that without focus! It's a journey to a holy place that will take him 87 days to complete, during which he considers his childhood, marriage and relationship with his son, and becomes an accidental media sensation . By the time he reaches his destination, you'll feel anything but tired. Finally, Ruth Ozeki's novelA Tale for the Time Beingwill charm the missing spark back into your life. Combining the diary of a sad Tokyo teenager with the story of the middle-aged novelist who finds it, washed ashore on a remote island off the coast of British Columbia, it's a beautiful illustration of how our lives touch -- and are touched by -- others in ways we mightn't even be aware of. This "Man Booker Prize" finalist has plenty to teach about Zen Buddhism, and unless you happen to live in one of its settings, it provides a bracing change of scene, too. One other suggestion: books, as we all know, make great companions but that doesn't mean they can't be enjoyed in the company of others. If you find yourself home alone, why not slip one into your back pack and head out to a favourite cafe.

[Q]: Article: The heart of Mexico is a high, oval valley surrounded by mountains. Once, forests covered the mountainsides, and broad, shining lakes covered nearly all the valley floor. Now, the mountains are bare and scarred with erosion , and much of the valley floor is dry and dusty. Cortez and his Spanish soldiers were the first Europeans to enter this valley. They saw the thriving Aztec city of Tenochtitlan rising from an island in one of the lakes. Surrounding it were green floating gardens. The Spaniards said it was as beautiful as a dream. Then the conquest began. By 1521, when the Spaniards had conquered the fierce Aztecs, the island city was in ruins. Cortez decided to rebuild it after the pattern of European cities. Using the conquered Aztecs as slave laborers, Cortez built the new city, now Mexico City, in just four years. "But a generation had scarcely passed after the conquest before a sad change came over these scenes so beautiful," writes one historian. The broad, shining lakes began to dry up. Modern historians believe that Cortez began the destruction of the valley's lakes when be ordered the city rebuilt. A great deal of charcoal was needed to burn the limestone from which cement and mortar were made. Wood was needed to finish the interiors of the buildings. The mountainside forests were destroyed to provide the charcoal and wood. Once the sloped were bare, rainfall o longer seeped slowly into the earth to feed the springs that filled the valley's lakes. Instead, rainfall poured off the mountainsides the city from floods, later rulers made a cut through the mountains so that the water drained away into another valley. Mexico City, once an island, had become a city of a dry plain.
