Until then she had been a bright, cheerful woman deeply interested and involved in the world around her. I would go home to visit her in Virginia and she would look at me in a puzzled way and ask, “Who are you?” I would answer, “I'm your son.” “Where do you live?” She would ask. “In California”, I would tell her. “Isn't that interesting,” she would say, “I have a son in California.”She seemed simply forgetful and confused at the beginning of the disease, but later on she would go through periods of intense anxiety. She would pace through the house she had lived in most of her life crying uneasily that she wanted to go home. Or she would leave home and wander away if she were unattended for a short time. Hoping to please her and put her mind at ease I would take her for a drive, visiting sites where she had lived as a child. In the yard of the hillside house in Shipman I sat in the car and admired the view of the old oaks and long green lawn. I pictured my mother there was a little girl playing with the pet lamb she had been so fond of. I looked to her for some response. She shookher head and said “ I want to go home.Over the years I have decided that what my mother was calling home was not a place, but a time. I suspect it was a time when she was much younger, when her children were still underfoot, when her husband was still vigorous and attentive.Watching my mother's suffering set me wondering where I would have gone in mind if someday I couldn’t find home and wanted to go there. In this family we tend to be long-lived and we grow fuzzy (糊涂的) minded as the years go by. At eighty I have already noticed some alarming symptoms. My doctor says the forgetfulness is only natural and that it comes with age. Still the fear of Alzheimer's is haunting there. Someday if and when I become even more cloudy minded than I am now, unable to drive and unable to tell you where "home" is, my dear son, I expect I will ask you to take me home, I know you will do your best to find the place I need to be. I leave these notes for your guidance.41. What's the main idea of the first two paragraphs?A. The author’s mother suffered with serious Alzheimer's disease.B.

Where are you most likely to find this text?A. In a newspaper.B. In a handbook.C. In a textbook.D. In a medical magazine.CIn the fall of 1985, I was a bright-eyed girl heading off to Howard University, aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere. Twenty-one years later I am still a bright-eyed dreamer and one with quite a different tale to tell.My grandma, an amazing woman, graduated from college at the age of 65.She was the first in our family to reach that goal. But one year after I started college, she developed cancer. I made the choice to withdraw from college to care for her. It meant that school and my personal dream would have to wait.Then I got married with another dream: building my family with a combination of adopted and biological children. In 1999, we adopted our first son.To lay eyes on him was fantastic—and very emotional.A year later came our second adopted boy.Then followed son No.3.In 2003, I gave birth to another boy.You can imagine how fully occupied I became, raising four boys under the age of 8!Our home was a complete zoo—a joyous zoo.Not surprising, I never did make it back to college full-time.But I never gave up on the dream either.I had only one choice: to find a way.That meant taking as few as one class each semester.The hardest part was feeling guilty about the time I spent away from the boys.They often wanted me to stay home with them.There certainly were times I wanted to quit, but I knew I should set an example for them to follow through the rest of their lives.In 2007, I graduated from the University of North Carolina.It took me over21 years to get my college degree!I am not special, just single-minded.It always struck me that when you're looking at a big challenge from the outside it looks huge, but when you're in the midst of it, it just seems normal.Everything you want won't arrive in your life on one day.It's a process.Remember: little steps add up to big dreams.51.When the author went to Howard University, her dream was to be ________.A.a writer B.a teacherC.a judge D.a doctor 52.Why did the author quit school in her second year of college?A.She wanted to study by herself.B.She fell in love and got married.C.She suffered from a serious illness.D.She decided to look after her grandma.53.What can we learn about the author from Paragraphs 4 and 5?A.She was busy yet happy with her family life.B.She ignored her guilty feeling for her sons.C.She wanted to remain a full-time housewife.D.She was too confused to make a correct choice.54.What does the author mostly want to tell us in the last paragraph?A.Failure is the mother of success.B.Little by little, one goes far.C.Every coin has two sides.D.Well begun, half done.55.Which of the following can best describe the author?A.Caring and determined.B.Honest and responsible.C.Ambitious and sensitive.D.Innocent and single-minded.DDeath Valley is one of the most famous deserts in the United States, covering a wide area with its alkali sand. Almost 20 percent of this area is well below sea level, and Badwater, a salt water pool, is about 280 feet below sea level and the lowest point in the United States.Long ago the Panamint Indians called this place “Tomesha”— the land of fire. Death Valley’s present name dates back to 1849, when a group of miners coming across from Nevada became lost in its unpleasantness and hugeness and their adventure turned out to be a sad story. Today Death Valley has been declared a National Monument(纪念碑) and is crossed by several well-marked roads where good services can be found easily. Luckily the change created by human settlement has hardly ruined the special beauty of this place.Here nature created a lot of surprising, almost like the sights on the moon, ever-changing as the frequent wind moves the sand about, showing the most unusual colors. One of the most astonishing and variable parts of Death Valley is the Devil’ s Golf Course, where it seems hard for one to tell re ality from terrible dreams. Sand sculptures(沙雕) stand on a frightening ground, as evening shadows move and lengthen.56. _______ is the lowest place in the desert.A. TomeshaB. Death ValleyC. NevadaD. Bad water57.

(机器)损坏;(计划;谈判)失败14. 有助于;造成 15. 对...某人严格三:阅读表达(15分)*1+ It’s good to make a mistake, and here is why. First of all, mistakes are a clear sign that you are trying new things. It’s always good to try new things because when you are trying new things you are growing. If you never try anything new, how can you improve? How can you expand? The simple answer is “You can’t”. Look around you. Almost everything valuable you see in your world is the result of _____________.[2] Another good thing about mistakes is this: when you are making mistakes, you are learning. Consider this: Edison failed 10000 times before he perfected the light bulb. When asked how it felt to fail that many times, he remarked that he hadn’t failed 10000 times, but rather had learned 10000 things that didn’t work.[3] Finally, when you make a mistake you are much closer to success. Why? Because when all is said and done, you will have tried only a few things before you succeed. Every time you made a mistake, you got rid of one bad thing and stepped closer to success.*4+ But this all doesn’t mean that you should go ahead without considering the consequences of a mistake. Instead, when you try something new, you have to be willing to set some reasonable limits so that you will have opportunities to try again in case that it doesn’t work out as you expected. We all have limited resources so don’t blow them all at one time. Realize that it probably won’t be perfect the first time and use these resources appropriately so you can learn, improve, and try it again. Only by using your mistakes in this way can you make significant advances in your career.*5+ There is an old saying that goes, “If you’re not making mistake, you’re not trying hard enough.” So go forth and make mistakes.1. List three reasons why making a mistake is good for you.
