Passage OneMy mother raised me with several fixed rules. One was that a gentleman always has a clean handkerchief in his rear（后面的）pocket. I can recall being a ten-year-old on the school playground， feeling the piece of cloth directly over my bottom and wondering what it was there for. Time would tell. Every night for most of my life, I have removed from my trousers the things I'm going to need the next day-keys, wallet, and handkerchief. After 60 years, my body weight feels wrong if I'm heading out of the house with an empty back pocket.This rule of behavior, of course, did not apply to one's children in the late 20th century. When my three kids were growing up, they all let me know that my handkerchief was ridiculously old-fashioned. They had their arguments. If you have to be prepared every day for a cold, why not carry a little packet of tissues，which saves you from that disgusting（恶心的）business o blowing your nose in the thing and then stuffing it back in your trousers?But a handkerchief is a lot more durable（耐用的）than tissue，creates no waste，and has a far wider variety of uses. One reason my kids saw that handkerchief so often is because of the large number of chocolate mouths and skinned knees that handkerchief wiped. Can you hold the handle of a boiling pot with a tissue? Now that I am a grandfather of five, my handkerchief again has been put to use. When friends become grandfathers for the first time, I often send them a dozen handkerchiefs as a small gift. In fact, for Father's Day last year my wife gave me several new handkerchiefs. Neither of us can count the number of times she was in tears at a movie and said quietly, "Can I borrow your handkerchief?”Which of the following is true about the writer when he was a ten-year-old?

Passage TwoAsk any group of parents to describe their eighth graders（八年级学生），and you＇ll get a surprising and often contradictory-range of responses. Eighth graders are often quiet and shy, yet they're often loud and frank. They keep pushing you away, yet they're still deeply influenced by everything you say and do. They can make a perfectly reasonable argument as to why they should be allowed to date, yet they can't seem to understand your perfectly reasonable argument for why they should wait. They want to be individuals, yet they want desperately to fit in.Welcome to the eighth grade! Your child is now a full-grown teenager, and she'll experience great physical，emotional，and intellectual（智力的）changes during this dramatic year. As she moves from childhood to adulthood（成年），she＇Il begin to look like a young woman，and she＇ll begin to struggle for the independence of adulthood, for which she's not quite ready yet. Your teenager will experience changes and feel emotions she won't always understand. As a result, she'll sometimes feel a little lost or scared, and often very confused as she struggles to figure out who she is and who she wants to be. That is where you come in. As much as your eighth grader may push you away, as much as you may feel she doesn't want you around, she does want you to be involved in her life. She needs you to know what's happening to her and around her, especially in school where she may face pressure to fit in and where she'Il face a curriculum that challenges her developing reasoning skills. As the saying goes, “Little kids, little problems; big kids, big problems." And your big kid will need you to help her work those problems out.Which of the following statements about eighth graders is true?
