The first successfully cloned animal was a sheep named Dolly in 1996. At first, Dolly grew normally, but later she developed an illness that is more normally found in much older animals. She lived for six and a half years, only half the life of the sheep from which she was cloned. After Dolly, scientists have cloned more than 20 mammal species, including camels, cattle, deer, dogs, goats and mice. However, they have found a similar pattern of health problems with these other species as well. 写法领悟：本段使用一系列的衔接表达，如at first, but later, after Dolly以及however等，具体介绍了人们一直在尝试人工克隆动物的过程，使行文连贯，过渡自然。还使用了named Dolly过去分词短语作后置定语，that引导的定语从句，以及“介词＋which”引导的定语从句，这些高级结构的使用使语言凝练，较好地表达了人们尝试人工克隆动物的细节。 2．赏用词及结构之美 There had been a number of failures before they eventually found a way to successfully clone a monkey.The reason they worked so hard to break this technical barrier was to get animals with edited genes and produce animal models that are helpful for medical research and human health. 写法领悟：本段使用了一系列的动词(短语)，如found，worked，break和produce等，刻画了研究者持之以恒的科学研究精神，同时也反映了探索克隆技术的艰辛与不易。使用了before引导的时间状语从句，省略关系副词why的定语从句，to get animals with edited genes动词不定式短语作表语，that引导的定语从句等多种高级句式表达，使行文流畅，增加可读性。 3．赏写作手法之美 An epidemic is the name given to an infectious disease that rapidly spreads to a large number of people within a short period of time — usually two weeks or less.Epidemics have been happening for as long as there have been people living on Earth.They can be caused by several different factors, such as a virus being carried into an area, or changes in the way people live, like more people living in an area, which increases the chances of them coming into contact with a virus or bacteria. 写法领悟：本段使用了说明文两种比较典型的说明方法。首先采用了下定义法介绍了流行病的基本概念，让读者对其有初步的认识；接着采用举例法，举出实际事例来说明流行病的起因，使所要说明的事物具体化，便于读者理解。 针对练笔 (根据提示完成句子) ① , the mountain trail was enveloped in a thick mist, , after the sun emerged, it revealed a breathtaking view. 起初，山间小径被浓雾笼罩，但后来太阳升起之后，它显露出了令人叹为观止的景色。 At first but later ②The book, the antique oak table _____________________, was worn from years of reading. 放置在窗边古老橡木桌上的那本书，因为多年的阅读而变得破旧不堪。 ③ and , pleased that my daughter could concentrate on her doll. 然后我转身又开始工作，很高兴我的女儿能专注于她的洋娃娃。 placed on that stood by the window Then I turned around set to work again [命题导向] 本单元主题是“人体生物学”，属于人与自我的主题语境。高考命制读后续写时，前文一般会描述人物生病、情感情绪变化等状况以及在此过程中家人、亲朋好友的行为表现及反应等，作为下文续写的伏笔。续写部分往往是进一步描述如何展现家庭亲情、社会友情互助以及带给人们的反思等。通过这种类型的命题，旨在引导学生思考家庭、社会中关爱的重要性，有助于培养学生正确的价值观、世界观，学会爱己爱人。　　 构建语义场 (一)疾病状况 1．develop an illness　　　　　 患病 2．an infectious disease 传染性疾病 3．lead to more effective treatments 达到更有效的治疗 4．take care of/care for 照料 5．When he was two years old, he suffered from autism that delayed his brain's growth. 当他两岁的时候，他患上了孤独症，这延缓了他的大脑发育。 6．No one had ever heard Diane say a word outside her home environment, who had caught selective mutism. 从来没有人听到Diane在家外说一句话，她患有选择性缄默症。 (二)家人的行为表现及反应 1．the worsening condition 正在恶化的情况 2．pass on love 传递爱心 3．sadden the family 使家人伤心 4．reach for my hand 伸向我的手 5．be proud to be her son 为能成为她的儿子而感到自豪 6．understand the love behind the words 理解这些文字背后的爱 7．John's parents, who were teachers, were initially shocked at the revelation. 约翰的父母都是老师，起初对这一消息感到震惊。 8．They kept his illness as a secret under medical advice, and were always there for their son. 他们遵医嘱对他的病情保密，并一直陪伴在儿子身边。 9．Diane's parents tried to work with her to overcome her disease.

I didn't want to go. I didn't want to see this side of my grandmother. However, her voice was so soft and familiar. It was a voice I couldn't disappoint. I followed the voice and went into her room. In her room, I didn't look at her. I just looked at the floor and told myself that this wasn't my grandmother — it just couldn't be. I was about to run out of the room when she spoke, “Once upon a time there was a boy named Billy ...” I raised my head and looked at my grandmother. Although her crumpled body hadn't changed, I could now see behind her appearance. I didn't fear to see Grandma that sick anymore. I went into her room every day after that. Every day she told me another story about a boy named Billy and I told her that little Billy loved his grandma very much. $$
