Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.‎ There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.‎ Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs your eyeballs begin to move quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.‎ If you have trouble falling asleep, some people recommend — breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.‎ ‎56. A good title for this passage is .‎ ‎ A. Sleep B. Good Health C. Dreams D. Work and Rest ‎57. The word “drowsy” in the last paragraph means .‎ ‎ A. sick B. asleep C. a little sleepy D. noisy ‎58. This passage suggests that not getting enough sleep might make you .‎ ‎ A. dream more B. have poor health C. nervous D. breathe quickly ‎59. All of the following will happen during REM except .‎ ‎ A. your eyeballs move quickly B. you don’t breathe ‎ C. your eyelids are closed D. you dream ‎ B It was early morning. Peter Corbett helped Mark Wellman out of his wheelchair and onto the ground. They stood before El Capitan, a huge mass of rock almost three-quarters of a mile high in California’s beautiful Yosemite Valley. It had been Mark’s dream to climb El Capitan as long as he could remember. But how could a person without the use of his legs hope to try to climb it?‎ Mark knew he couldn’t finish the climb alone, but his friend Peter, an expert rock climber, would be there to lend a helping hand. He and Mark thought that it would take seven days to reach the top.‎ Peter climbed about 100 feet up and hammered a piton(岩钉) into the rock. Fastening one end of a 165-foot rope to the piton, he let one end of the rope fall down. Mark caught the rope and fastened it to his belt with a special instrument.‎ ‎ This instrument would allow Mark to move upward, but would prevent him from falling even as much as a single inch. He next reached above his head and fastened a T-shaped bar to the rope, using the same kind of instrument.‎ Mark took a deep breath, pushed the T-bar up almost as far as his arms could reach, and began the first of the 7, 000 pull-ups needed to reach the top. High above, Peter let out a cheer: “You’re on your way.” ‎ Seven years before, at the age of twenty-one, Mark had fallen while mountain climbing, injuring his backbone. The fall cost him the use of his legs, but he never lost his love for adventure or his joyful spirit.‎ For the first four days the two men progressed steadily upward without incident. But on the fifth day an unbearably hot wind began to blow, and as time went by, it became stronger and stronger, causing Mark to sway(摇摆) violently on his rope. But Mark kept on determinedly pushing up the T-bar and pulling himself up. In spite of that, he had to admit that he felt a lot better when the wind finally died down and his body touched solid rock again.‎ It took them one day more than they had expected, but on July 26 at 1:‎45 in the afternoon, the crowd of people waiting on the top went wild with joy as the two heads appeared. Mark Wellman had shown that if you set your heart and mind on a goal, no wall is too high, and no dream is impossible.‎ ‎60. What had Mark Wellman long desired to do?‎ ‎ A. To finish one of the most difficult rock climbs — El Capitan.‎ ‎ B. To be the first to climb El Capitan.‎ ‎ C. To climb the highest mountain in California.‎ ‎ D. To help his friend Peter climb El Capitan.‎ ‎61. How did Mark lose the use of his legs?‎ ‎ A. He once had a fall while mountain climbing and injured his backbone.‎ ‎ B. He fell during his first attempt on El Capitan.‎ ‎ C. His legs were broken by falling rocks.‎ ‎ D. While working out in the gym, he injured his backbone.‎ ‎62. What was the worst problem Mark had during the climb?‎ ‎ A. He struck against the rock and hurt his arms.‎ ‎ B. A strong wind blew him away from the rock.‎ ‎ C. He kept falling several inches.‎ ‎ D. While swaying in space, he became terrified.‎ C Life is difficult, but it is a great truth that once we truly understand and accept it, life is no longer difficult. 　　Most do not fully see this truth. Instead they complain about their problems and difficulties as if life should be easy. It seems to them that their difficulties represent a special kind of suffering especially forced upon them or else upon their families, their class, or even their nation. 　　What makes life difficult is that the process of facing and solving problems is a painful one. Problems, depending on their nature, cause in us soreness or loneliness or regret or anger or fear. These are uncomfortable feelings, often as ‎ any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy. 　　Yet, it is in this whole process of solving problems that life has its meaning. 　　Problems are the serious test that tells success from failure. When we desire to encourage the growth of the human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve, it is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, “Those things that hurt instruct.” It is for this reason that wise people learn not to fear but to welcome the pain of problems. 63. From the passage, it can be inferred that . 　 A. nobody has problems ‎ B. we become stronger by facing and solving the problems of life 　 C. life is difficult because our problems bring us pain 　 D. people like to complain about their problems ‎64. The saying from Benjamin Franklin “Those things that hurt instruct” suggests that .‎ ‎ A. we do not learn from experience ‎ B. we do not learn when we are in pain C. pain teaches us important lessons ‎ D. pain cannot be avoided ‎65. The underlined word in Paragraph 3 means .‎ A. happiness B. pleasure C. sadness D. despair 第二节 (共5小题；每小题2分, 满分10分)‎ 根据短文内容,从短文后旳选项中选出能填入空白处旳最佳选项.选项中有两项为多余选项.‎ Ben Franklin once said, “Early to bed and early to rise makes a man healthy, wealthy and wise.” 66 So you many wonder how to became an early riser. Here are a few tips:‎ ‎ 67 Start slowly, by waking just 15-30minutes earlier than usual. Get close to this for a few days. Then cut back another 15 minutes. Do this gradually until you get to your goal time.‎ ‎ 68 You might be used to staying up late, perhaps watching TV or surfing the Internet. I suggest going to bed earlier, even if you don’t think you’ll sleep, and read while in bed. If you’re really tired, you just might fall asleep much sooner than you think.‎ Put your alarm clock far from your bed. If it’s right next to your bed, you’ll shut it off. If it’s far from your bed, you have to get out of bed to shut it off. By then, you’ve been up. 69 Don’t make getting back in bed an option.‎ Set something important to do early in the morning. This will force you to get up.‎ ‎ 70 You can make a cup of hot coffee or tea for yourself and read a book. You can also treat yourself to a tasty breakfast. It might seem at first that you are forcing yourself to do something hard, but if you make it pleasurable, soon you will look forward to getting up early.‎ A. Allow yourself to sleep earlier.‎ B. Don’t wake up early and waste that extra time.‎ C. Making getting up early a reward.‎ D. Actually, there are many other great benefits.‎ E. Get out of the bedroom as soon as you shut off the alarm.‎ F. There’s no need to change, especially if you’re happy with it.‎ G. Don’t make sudden changes.‎ ‎ ‎ 第II卷 (非选择题 共35分)‎ 第四部分 写作（共三节，满分35分）‎ 第一节 单词拼写（共10小题；每小题1分，满分10分）‎ ‎ 根据下列句子及所给汉语注释，在相应旳横线上写出各单词旳正确形式.‎ ‎71.
