A Last week I was sitting in the hall of a medical building when I heard an elderly woman talking on the phone about her husband. His name was Ed and he dropped her off for her doctor's appointment, and was going to park the car and wait for her. She was so upset because he never came back to get her. As she described her situation to the person on the phone she started to cry and I knew I needed to take action. After I introduced myself, she told me her name was Helen. She was talking to a local restaurant they were going to have lunch at after her appointment. She called to see if he was there. She explained her husband "Ed" was supposed to park the car and wait for her. Then she said," My husband has Alzheimer's (早老性痴呆症)and he shouldn't be driving without me." Numerous thoughts ran through my head. Call the police, call her family, call the doctor's office she had just come from ! I offered to drive to the local restaurant to see if Ed was waiting for her there. After telling the nurse about the situation we exchanged cell phone numbers in case Ed showed up as I jumped into action searching for him. Once arriving in the parking lot of the restaurant, Helen described she received a call from the nurse, who had found Ed sitting on a bench in front of the hospital a few buildings down waiting for her. What a relief ! Once reunited, we needed to find his car which he forgot where he parked! Fortunately, he parked in the handicapped(残疾的)spot so it was easy to find! Once all this was done, I followed Ed and Helen home to be sure they arrived safely. After I waved goodbye and wished them my best, I thought, "That is the kind of love in life, simple but deep. " What was Helen's reaction when she couldn't find Ed ? A. She was going to telephone the police. B. She asked the doctor and the nurse for help. C. She went to look for him everywhere. D. She was terribly worried about him. What do we know about Ed's driving ?A. He is often fined by the police.B. He can't drive without Helen's help.C. He always drives very carefully.D.

C. parked the car and then couldn't find his wife D. drove to the restaurant to look for his wife. Who was it that told the author Ed had been found ? The nurse. B. The doctor.C. The police.D. Helen. Which of the following could be the best title of the passage ?A. Driving with Alzheimer'sB. Love from strangers.C. Simple but deep loveD. The handicapped in trouble. B Once, looking for stories on the back roads of Ohio, we were suffering a week-long dry spell. Abeekeeper we'd been told about was away from home when we called on him. An amusement park where we thought we might find a story had shut down for the season. We began to get a little discouraged. When passing a farmhouse, we found a banner(横幅)in the front yard. The banner said in huge letters: WELCOME HOME, ROGER! We drove on for a mile or two. Somebody said, " wonder who Roger is ?" We turned around, went back and knocked on the door. Roger was a soldier on his way home from the Vietnam War. His family knew he was coming, but weren't sure what day he was going to arrive. We asked if they 'd mind if we brought the camera into the house. Roger's mother said it would be all right if we could give her a few minutes to fix her hair. We weren't there more than an hour, talking to those people who were all excited about Roger coming home. That afternooon I wrote a simple story letting Roger represent all the soldiers coming home from war. We sent the film with the story to New York, and the anchorman(主持人)put it on the Evening News. Rarely has any of our stories caused such a reaction from viewers. There were dozens of calls from people moved by it, and hundreds of letters came in, some of them suggesting that the story be repeated. That hour with Roger's family made it a good trip to Ohio, after all. I had done a lot of careful planning for the week's work, but in vain. Then along came a banner in a farmhouse yard. Back at the office, people asked , " How do you find these stories ?" "Well," I said," you do have to work at it." All you really have to do is look out of the window. By saying " we were suffering a week-long dry spell", the author means that ________________. A. they were suffering dry weather for a week. B. they were getting nowhere with their work for a week. C. they were having a hard time finding their way for a week. D. they were having trouble in spelling for a week. Why did they drive back ? Because a stranger called for them. Because they passed by their destination. Because they wanted to make friends with Roger. Because they thought they may find a story about Roger. What can we learn from Paragraph 6 ? A. Careful planning didn't work. B. Only Roger's family served us. C. Only Roger appeared after our hard preparation. D. We didn't want to continue to look for stories. What can be learned from the passage ? A. Roger's family were excited at the author's coming. B. Roger was a soldier who was fighting at the front. C. Roger's mother was eager to share Roger's story with us. D. Roger's story went directly into the viewers' hearts. From the story the author wants to tell us ________________. to do careful planning for everything. to keep learning by reading stories. to see life with one's heart to work hard at everything C Every day, young people across the globe are doing their part to keep the Earth healthy and green. These are just a few kid heroes for the planet. Manatee (海牛) Minder When she was in second grade, Stephanie Cohen read about a baby manatee hit by a boat off the coast of Florida.

Section B (10 points) Directions: Read the following passage carefully and answer the questions according to the information given in the passage and the required words limit.Write your answer on your answer sheet. Though I don't have much money, I always try to think positively. However, sometimes, I also feel depressed and sad when I think how others have more than me, so I hate thinking about money. When I was younger, I always wondered why money was so important. But as I get older, of course that changes. Last night, on my way home I stopped by to buy some hamburgers at a fast food restaurant. On my way in, a homeless man came over and asked, " Do you have any bottles lying around ?" I knew he would recycle them for a few cents, but I had none. And again he asked, " Can you spare some change ?" I smiled and said," Sorry, I don't. " He was respectful, saying , "OK, thank you." Though he didn't have anything , he was still in good spirits. I went in and ate my meal, but I wondered if he was hungry, thinking if I should buy him something or not. Only after I finished my meal did I decide to order another one for him. At this point I didn't know if he was still around, but I tried anyway. At the counter I ordered a hamburger and also a hot chocolate, for it was cold outside. As I waited, I noticed the homeless man standing beside me with a tray (盘子)full of a few coins. I looked at him and smiled, " The hamburger and this hot chocolate are for you." He replied like a gentleman,"Thank you. That's very kind of you." No matter how hard your life is, there are always those whose life is harder. And it's not always about happiness, but it's about love. If you love someone, you'll give them what they deserve because the greatest thing you can give is love. 81.Why does the writer hate thinking about money?(No more than words) (No more thanords)高一参考答案 Good luck ! Yours, Tom。
