6 阅读理解。 The week I turned 50, my marriage came to a sudden end. My house, furniture and everything I"d owned was sold to pay debts that I didn"t even know I had. In a week I had lost my husband, my home and my parents who had refused to accept a divorce (离婚) in the family. I"d lost everything except my four teenage children. I used every penny I had to buy five plane tickets from Missouri to Hawaii. Everyone said I was crazy to think I could just run off to an island and survive. I was afraid they were right. Knowing that no one in the world was going to help us, I rented a cheap apartment. I worked 18 hours a day and lost 30 pounds because I lived on one meal a day. One night as I walked alone on the beach, I saw the red orange glow of the lava (火山岩) pouring out of Kilauea Volcano in the distance. It was time to live my imagination! The next day, I quit my job and invested my last paycheck in art supplies and began doing what I loved. I hadn"t painted a picture in 15 years. I wondered if I could still paint. My hands trembled the first time I picked up a brush. But before an hour had passed, I was lost in the colors spreading across the canvas (画布) in front of me. And as soon as I started believing in myself, other people started believing in me, too. The first painting sold for $ 1500 before I even had time to frame it. The past six years have been filled with adventures. My children and I have gone swimming with dolphins, watched whales and hiked around the crater (火山口) edge of the volcano. We wake up every morning with the ocean in front of us and the volcano behind us. The dream I had more than 40 years ago is now reality. I"m living freely and happily ever after. 1.

9 阅读理解。 As my dad unwrapped the new bicycle helmet (头盔) that I got him for his birthday, I realized that a number of people ride their bicycles every day without the protection of a helmet. Due to cold winters across the country, riding has become increasingly dangerous as many roads have potholes and are torn-up (磨损的). Not everyone realizes that there are laws requiring the wearing of helmets in many places. Where I live, there has been a law in place since October l, 1992 stating that cyclists of all ages are required to wear helmets. Unfortunately, accidents can happen to the best of riders. My dad has been a cyclist for many years, and he often rides around my county and to Rockland Lake State Park. One afternoon, as he was just entering the park, he lost control of his bicycle and flew off and landed on a nearby patch of grass, breaking his helmet into pieces and losing consciousness. When he was just awakening, a lovely couple found him and brought him back to our house, where he attempted to recap the events leading up to his fall. Later that day, a CAT scan revealed that he had a concussion(脑震荡). That evening, while my dad was showing me the pieces of his broken helmet, we both came to a shocking realization. If he had not worn his helmet, he probably would have cracked his skull and perhaps died. Today, when my dad and I go out cycling, the wearing of our helmets is not even a question. Regardless of age, everyone should wear a helmet whenever they get on a bicycle. 1. According to the passage, which of the following statements is TURE? A. Young men needn"t wear helmets. B. The writer"s father didn"t wear a helmet until the writer bought him one. C. People don"t have to wear helmets on smooth surface roads. D. Accidents do not happen to the best cyclists. 2. In the writer"s opinion, why should people wear bicycle helmets? A. Because a law requires them to do so. B. Because many people like wearing bicycle helmets. C. Because people have realized the importance of wearing helmets. D. Because the conditions of roads are very poor and it is dangerous to ride on them. 3. The underlined part "we both came to a shocking realization" in Paragraph means "____". A. we understood how lucky the dad was to have worn a helmet B. we were shocked to see the broken helmet C. we realized that young people needn"t wear helmets D. only old people should wear helmets 4. From the accident that happened to the writer"s dad, we can infer that ____. A. the cyclists should follow the law B. his dad was not worried about this accident C. it is necessary for cyclists to wear helmets D. everyone should care about life
