It was the middle of third grade and I was not sure what had got into me. I lied about many things -- I lied that I had eaten all my dinner, when in fact I buried it in the trash can. I lied that I had made my bed, when clearly I had not. My lies were not hurting anyone, but for some reason I felt the need to tell lies on an impulse that didn't feel like my own. I was labeled a liar. One day my sisters and I were invited to spend the weekend with my aunt. We all loved it. She spoiled us with her time.And she was an amazing artist. She had cool pencils, erasers and other supplies that any young girl would love to get her hands on. Then it happened...someone took one of Aunt Kim's good art erasers and rubbed it across the entire top of the TV. The eraser ruined the shiny finish on the TV's casing. All the three of us were called into the TV room and asked to admit. Nobody did! Aunt Kim told us how disappointed she was. The next thing I knew was that she was on the phone with my parents and they were on their way to picking me up. It had to be me! I was the liar. I argued, but no one listened. And then before dinner there was a knock at the front door! Aunt Kim was standing there. It turned out my younger sister finally felt guilty! She admitted that she was the one who rubbed the eraser on the TV. I was invited back! A lie may take care of the present, but it has no future.

B) She can find pleasure in telling a lie. C) She is afraid to admit her mistakes. D) She likes to play tricks on others.

You may have heard of the American Dream, an ideal that has powered the hopes of Americans for generations. It began as a belief that the US was a land of opportunity, and that anyone could achieve success through hard work. At times, the dream has referred to home ownership, a good job, retirement security or each generation doing better than the last. Yet today, this concept seems to have greatly changed. As Time magazine pointed out, quite different from the older generation, many Millennials (the generation born after 1980) redefine the American Dream as "day-to-day control of your life". They "prize job mobility, flexible schedules, any work that is more interesting than typing, and the ability to travel", said the magazine. Home ownership, once the _ of the American Dream, is becoming a smaller priority for this generation. Meanwhile, nearly 40% of them choose travel as part of their dream. And entrepreneurship is a rising favorite, as nearly 26% of Millennials consider self-employment as part of their dream. So what has led to this huge change? Many point fingers at the poor economy. "Modern young Americans seem bound to face a world stamped by ever narrowing opportunity and social stagnation ,"noted The Daily Beast. "The rate of 16-to 24-year-olds out of school and out of work is unusually high at 15%. Many college graduates have taken jobs that don't require a degree," Time reported. The magazine worries that these difficulties may lead to a lost generation who are "unable to ever truly find their feet on the corporation's ladder". Dan Kadlec, a reporter of Time, sees Millennials as resetting their expectations."This situation is different for young adults today," he wrote. "A true American dream has to feel attainable, and many Millennias are feeling they can only attain a day-today lifestyle that suits them." What can be the best title for this passage? A) Redefinition of American Dream B) Meaning of American Dream C) Value of Achieving American Dream D) History of Changing American Dream
