Paragraph 2：I looked at our sleeping daughter. 写作步骤第一步：速读全文文本大意：作者接到了一个电话，电话中的女孩错把作者当成自己的妈妈，女孩跟作者说的一些话触动了作者的心灵。叙述意图：文章告诉我们要学会倾听。第二步：细读全文1所给短文情景模式分析。whoI, a young girl, my daughter, my husbandwhatA young girl mistook the author for her mother and called to tell the author to learn to listen to her. whenmidnightwhereat homewhyThe girl ran away from home and felt lonely. She wanted her mother to listen to her.2对原文所提供的下划线词语进行分类。人物：my daughter, my husband, kid, mother事件：crying voice, wrong动作与心理描写：breath, call, return, listen第三步：精心谋篇1Paragraph 1：I went to my 16yearold daughters room. 我去了我16岁女儿的房间。情节分析根据前文“电话中的女孩错把作者当成自己的妈妈，女孩跟作者说的一些话触动了作者的心灵”这一故事情节，并结合“I went to my 16yearold daughters room.”这一开头语，合理想象作者去女儿卧室后发生的事情和相应的心理活动。进入卧室发现女儿在熟睡，结合全文主题“倾听”，可知夫妻二人会从中得到启发，要学会倾听。2Paragraph 2：I looked at our sleeping daughter.我看着我们熟睡的女儿。情节分析根据段首句可知，此处作者应该先叙述女儿现在睡觉的情况，她面带微笑地睡着了，她不知道发生了什么事，她不知道她妈妈刚刚学到了一些重要的东西。最后要回归主题学会倾听。第四步：初写成文Paragraph 1：1我丈夫从后面过来。My husband came from_behind.2我女儿静静地睡着。My daughter was_sleeping_quietly.3我看着我的丈夫，他也看着我。I looked at my husband, and he was also looking_at me.4“我们必须学会倾听，”我对他说。“We have to learn_to_listen，” I said to him.5他打量了我一会儿，然后问道：“你认为她会知道她打错电话了吗？”He studied me for a second, and then asked, “Do you think she will ever know that she dialed_the_wrong_number？”Paragraph 2：6她面带微笑地睡着。She was sleeping and there was a smile on_her_face.7也许她正在做一个好梦。Maybe she was having a_nice_dream.8她不知道发生了什么事。She didnt know what_had_happened.9她不知道她妈妈刚刚学到了一些重要的东西。She didnt know her mother had learned something_important just now.10告诉孩子们该做什么是必要的，但更重要的是要听他们说。Its necessary to tell children what to do, but its_more_important to listen to them.11我在那里站了一会儿，想了整件事情。I stood_there_for_a_while and thought about the whole thing.12我回头看了看我的丈夫，对他说：“也许这不是一个错的号码。”I looked_back_at my husband and said to him, “Maybe it wasnt such a wrong number.”第五步：润色升级1用with复合结构改写要点6。She_was_sleeping_with_a_smile_on_her_face.2用同源宾语结构改写要点7。Maybe_she_was_dreaming_a_nice_dream.3用分词作状语改写要点11。I_stood_there_for_a_while,_thinking_about_the_whole_thing.第六步：复查定稿Paragraph 1：I went to my 16yearold daughters room.My_husband came from behind. My_daughter was sleeping quietly. I looked at my husband, and he was also looking at me. “We have to learn to listen，” I said to him. He studied me for a second, and then asked, “Do you think she will ever know that she dialed the wrong number？”Paragraph 2：I looked at our sleeping daughter. She was sleeping with a smile on her face. Maybe she was dreaming a nice dream. She didnt know what had happened. She didnt know her mother had learned something important just now. Its necessary to tell children what to do, but its more important to listen to them. I stood there for a while, thinking about the whole thing. Then I looked back at my husband and said to him, “Maybe it wasnt such a wrong number.”一、复现单元考点增强备考信心.高考中的语法填空1(2018江苏高考)Try to understand whats actually happening instead of acting on the assumption (assume) youve made.2(2017北京高考)Jim has_retired (retire), but he still remembers the happy time spent with his students.3(2016浙江高考)In many ways, the education system in the US is not very different (differ) from that in the UK.4(2015全国卷)As natural architects, the Pueblo Indians figured out exactly (exact) how thick the adobe walls needed to be to make the cycle work on most days.5(2015湖北高考)He gave himself a new name to hide his identity (identical) when he went to carry out the secret task.6(2013广东高考)“That would be a very reasonable (reason)thing to do in a big city, but it could destroy a small village like ours，” Nick said.高考中的完形填空(选用owe, strike, forbid, bother, obtain, pay off填空)1(2017天津高考完形填空)My goal was to lose 150 pounds in one year and raise 50,000 in support of a movement founded 30 years ago to end hunger.
