day i entered it for the first time.donna was a school teacher only two years away from retirement. in addition she was a volunteer participant in a project i had organized. the training focused on language arts ideas that would make students feel good about themselves and take charge of themselves. donnas job was to attend training classes and carry out the ideas being presented. my job was to make classroom visits and ensure the ideas to be carried out. i took a seat in the back of the room and watched. all the students were working on a task, filling a piece of paper with thoughts. “i cant kick the soccer.” “i cant get debbie to like me.” everyone was writing sentences, describing things they couldnt do. thinking why students and teacher were focusing on the negative instead of writing the more positive “i can” statements, i returned to my seat and continued my observations.“finish the one youre on and dont start a new one,” said donna. students were then instructed to put the papers into an empty box in the front. when all of the students paper was collected, she put the lid on the box and headed down the playground.donna asked the students out to the corner of the playground. there they began to dig. they were going to bury their “i cants”. the box of “i cants” was placed in a position at the bottom of the hole and then quickly covered with dirt.now, years

in nature actually clone themselves and reproduce asexually. cloned plants are much more predictable than normal plants, so their yield (产量) is more reliable. cloned plants also reproduce faster, limiting the amount of time between planting and harvesting. it is also often cheaper to produce seeds through cloning than through traditional methods. plants can essentially be optimized so that farmers or individual growers always have the best seeds available. with more yield at a faster rate, farms can produce more food for more people while decreasing overall costs. cloning can be used to wipe out diseases that previously killed off entire fields of crops. this would make plants immune (免疫的) to the kinds of diseases that farmers and gardeners around the world fear each year. crop failures due to disease and virus could become a thing of the past. also, plants that are near extinction can be brought back to life through cloning. through cloning scientists can develop “super” fruits and vegetables of superior nutritional quality. this could make for a healthier population overall. this is already being done through selective pollination (授粉), and genetic cloning could take it to the next level. by plant cloning we have a population of identical plants and all these plants equally suffer from the same diseases, but in nature the weak would die and the strong would survive. while there are some dangers to consider with plant cloning, there are plenty of benefits that could prove vital to the propagation (繁衍) of the human species.44. the underlined word “optimized” in paragraph 2 can be replaced by “ ”.a. enlargedb. producedc. perfectedd. examined45. according to the text, cloned plants .a. have lower yield than normal plantsb. need little care from peoplec. resist various kinds of diseases d. have a short growth cycle46. what can we infer from the text?a. the fruits produced by cloned plants taste much better.b. there are more cloned plants than normal plants.c. plant cloning can disturb the laws of nature.d. people should avoid eating cloned fruits.47. what is the main purpose of the text?a. to warn the negative effects of plant cloning.b. to present different kinds of plant cloning.c. to predict the future of plant cloning.d. to inform us about the advantages of plant cloning.d a new study finds that a species of sea star stays cool using a strategy (策略) never before seen in the animal kingdom. the sea stars soak up (吸收) cold sea water into their bodies during high tide to protect themselves against potentially damaging temperatures brought about by direct sunlight at low tide.“sea stars were assumed to be unable to do anything to protect themselves from the sun during low tide,” said the studys lead author, sylvain pincebourde of franois rabelais university in tours, france. “this work shows that some sea stars have an unexpected back-up strategy.”sea stars need to tolerate rapid changes in temperature. during high tide, they go under the surface of cool sea water. but when the tide is out, the sea stars are often left on rocky shorelines, lying in the sun.clearly the sea stars had some way of beating the heat, but scientists were unsure how they did it. pincebourde and his team thought it might have something to do with fluid-filled cavities found in the arms of sea stars. so he set up an experiment to test it.the researchers placed the sea stars in fish tanks and varied the water level to simulate (模仿) tidal patterns. heat lamps were used to control temperature, with some sea stars experiencing higher temperatures than others. the researchers found that the sea stars exposed to higher temperatures at low tide had higher body mass after the high tide that followed. since the sea stars were not allowed to eat, the increased mass must be from soaking up water.“the reservoir of cool water keeps the sea stars from overheating when the tide is out again the next day,” pincebourde said.48. people used to believe that sea stars .a. saved a lot of water in their body to feed themselves at nightb. had no way to protect themselves from the sun during low tidec. could adapt themselves to temperature changes during low tided. could fill their body with cool or warm water at different times49. the reservoir of cool water helps the sea star .a. get energy during low tide b. get back to the sea during high tidec. to stay wet enough until the next high tide d. keep his body temperature cool in the sunlight 50. the result of the research shows that .a. the sea stars can survive in water only b. the sea stars are very sensitive to lightc. the sea stars become larger in size after high tided. the sea stars will starve themselves during high tide第二节

discovered diamond mines. these tales excited the farmer so much that he could hardly wait to sell his farm and hunt for diamonds himself. so he sold the farm and spent the rest of his life wandering the african continent, searching unsuccessfully for the gleaming (闪烁的) stones. 52 meanwhile, back on the farm, the man who had bought his farm happened to be crossing a small stream on the farm one day. 53 he picked it up. it was a sparkling stone a good size stone and, admiring it, he later put it on his mantel (壁炉架). several weeks later, a visitor looked closely at it, then he nearly became unconscious. he told the farmer it was one of the largest diamonds ever discovered. the farmer said that the stream was full of these brilliant stones, and his farmland was covered with them. 54 if the first farmer had taken time to study and prepare himself to learn what diamonds looked like in their rough state and to thoroughly explore the farm he had before looking elsewhere, his wildest dreams would have come true. 55 a. id like to give you some advice on how to find the riches. b. now do you have any idea of what you should do to find the riches?c. finally, he threw himself into a river and drowned.d. however, something special he was carrying dropped into the stream. e. needless to say, the farm turned out to be the most productive diamond mine.f. before i answer your questions, i want to tell you a story.g. suddenly he saw something gleaming at the bottom of the stream.四、写作（共两节，满分35分） 第一节 短文改错
