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.

Article: When I was a kid, I was just like every other kid. As usual, I liked being with friends and having fun. But I didn't like school much. I didn't like the rule of learning, studying, memorizing, etc. Too much work. As I got into high school, things changed for me. I started reading a lot of books. Books taught me about life and helped me learn about the world. I read around 30 books during each senior year. I learned to love reading then. Little did I know at that time that I would write books by myself. I've written 7 books since then. One book I wrote, Powerful Attitudes, was a huge success within a network marketing company in the USA. When I was 17 years old, I took about a dozen guitar lessons. I fell in love with guitar music no matter if it is blues, rock, flamenco or classical. I've attended concerts and have heard some great guitarists through the years. Recently, I bought myself a piano and began to learn to play it. I've made great progress. My knowledge of music and playing guitar has helped me a lot in learning the piano. Last week, I employed a Chinese teacher to teach me Chinese. I've learned about 200 words in my first week. I'm inspired and motivated to learn. In fact, I feel a bit _ , thinking of learning Chinese. It's like a mountain I want to climb and conquer. I'm 56 years old and my love to learn it runs deep in my heart, mind and soul. What I certainly learned while growing up is to love learning. I never want to stop learning. I never want to stop studying people, life, processes and new things. I think the openness of admitting what you don't know, makes you a good learner. You never lie to yourself or to others about your knowledge and experience. I have the attitude that if I don't know something, I will learn to know it.
Question: What can we learn about the author from the passage?
Options: (A) He fell in love with reading when he was a child. (B) One of his books enjoyed a lot of success. (C) He began to love music recently. (D) He is good at Chinese.

Article: Adults usually do not remember most of the things that are taught by their teachers at school. But this story is one such lesson that I will never forget. Every time I drift off course, I think of this story. It was a normal Monday morning, and my teacher was teaching us on important things in life and about devoting ourselves to what is important to us. This is how the story went: An old man lived in a certain part of London, and he would wake up every morning and go to the subway. He would get onto the train right to Central London, and then sit at the street corner and beg. He would do this every single day of his life. He sat at the same street corner and begged for almost 20 years. His house was dirty, and a stench came out of the house and it smelled terrible. The neighbors could not stand the smell any more, so they called for the police officers to clear the place. The officers knocked down the door and cleaned the house. There were small bags of money all over the house that he had collected over the years. The police counted the money, and they soon realized that the old man was a millionaire . They waited outside his house expecting to share the good news with him. When the old man arrived home that evening, one of the officers told him that there was no need for him to beg any more as he was a rich man now, a millionaire. But the old man said nothing at all; he went into his house and locked the door. The next morning he woke up as usual, went to the subway, sat at the street corner and continued to beg. Clearly, this old man had no great plans, dreams or anything significant for his life. We learn nothing from this story other than staying focused on the things we enjoy doing.
Question: The neighbor called the police because _ .
Options: (A) the old man kept begging money from them every day (B) there was something dangerous in the old man's house (C) the old man wouldn't buy tickets for the train (D) they couldn't bear the smell from the old man's house
