As far as I am concerned，a scientist is supposed to have some scientific qualities as follows． Firstly，scientists should be interested in，and curious about certain things．They pay attention to various aspects of the research problem and keep exploring．In addition，scientists need to be imaginative and willing to experiment bravely with new ideas and methods．As we all know，scientists UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 are often intelligent and able to form independent opinions and methods．Caution and persistence are also of great importance for scientists to succeed． Becoming a scientist is not easy．Stick to the dream and it will become a reality sooner or later． UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 Ⅱ　读后续写 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。 As Lia Bentley walked home from school on a cold October afternoon，she saw symmetry(对称) all around her: in the faces of people and the clothes they wore，in the buildings she passed and in the cars that went by．The birds in the sky were symmetrical，even the autumn leaves that covered the sidewalk． UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 All the month，Lia's class had been studying different forms of symmetry，and Lia was very interested．Mr． Ferris，their science teacher，had given them their final task: to find the most beautiful example of symmetry and give a report to the class on it． Lia looked at the task in her notebook．The most beautiful example of symmetry，she thought．What on earth could that be？Halfway through the school year，she'd been given a microscope(显微镜) for her birthday．Now she realized that she could use it to study symmetry．She set up what she called “laboratory” in the small wooden house．The microscope stood on a UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 table．She hoped to find an example of symmetry that would stand out from all the others．Lia spent hours on the examination of cells and drops of pond water full of strange symmetrical life．Although she was surprised by what she saw，it troubled her that none of it was truly beautiful．Lia stayed in the wooden house until her father called her inside．“Come on，Lia．It's getting cold out．The weather forecast says it's going to snow．” UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 Lia suddenly felt sad．Snow meant winter was on its way．The cold weather would mean fewer things to look at under the microscope．Snow would often cover the area like a blanket，hiding everything from sight． “Come inside！” her father called again． “Be there in a minute，Dad！” Lia called back． Just then，the door of the wooden house was blown open by a short strong wind．As she turned her head against the wind，she caught sight of a single snowflake(雪花) that had blown into the wooden house and onto the stage(载物台) of her microscope． UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 注意： 1．续写词数应为150左右； 2．请按如下格式在相应位置作答。 Paragraph 1： Lia looked through the microscope，and to her surprise，she saw the most beautiful example of symmetry she could ever have imagined． ________________________________________________________ ________________________________________________________ ________________________________________________________ UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 Paragraph 2： Suddenly，Lia had an idea—she ran to her house and picked up her camera． ________________________________________________________ ________________________________________________________ ________________________________________________________ UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 [巧读文] 1．读要素 Who：Lia Bentley；Lia's father；Mr．Ferris，Lia's science teacher Where：at school and at home What：After learning about symmetry，Lia Bentley followed the science teacher's requirements and successfully completed the observation and report，which was praised by everyone． UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 2．读双线(情节线、情感线) 情节线： UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 [妙构思] 1．读首句，定方向 Paragraph 1： 由续写第一段首句“Lia looked through the microscope，and to her surprise，she saw the most beautiful example of symmetry she could ever have imagined．”可知，莉娅通过显微镜观察，看到了她能想象到的最美丽的对称的例子。由此可推知第一段可描写莉娅找到目标物体时的激动之情。由续写第二段首句“Suddenly，Lia had an idea—she ran to her house and picked up her camera．”提到的莉娅想到用照相机给雪花拍照的主意可知，第一段后半段可描写她遇到的困难——雪花很容易就会融化，更别提带去学校做报告了。 UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 Paragraph 2： 由续写第二段首句“Suddenly，Lia had an idea—she ran to her house and picked up her camera．”可知，莉娅有了一个主意——她跑回家拿照相机。由此可推知该段首先要描写莉娅拍照的过程；结合上文情节可知，文章结局可描述莉娅顺利地完成了观察和报告，受到大家的赞许。 UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 2．巧设问，定细节 Paragraph 1： (1)What did Lia say? ____________________________________________________ (2)What did Lia do? ____________________________________________________ A snowflake！Why didn't I think of that before？/ ... looked through the microscope again / ...
