答案
1. 160 cm; 163 cm; 170 cm; 168 cm; 175 cm
2. 45 kg; 43 kg; 60 kg; 55 kg; 60 kg
2. 45 kg; 43 kg; 60 kg; 55 kg; 60 kg
解析
【分析】
这是一道阅读理解细节题，解题思路如下：
1. 首先定位短文里给出的基准人物Sarah的身高（160cm）和体重（45kg），这是计算其他人数据的基础；
2. 针对每个问题，分别查找短文中对应人物与已知人物的身高、体重比较关系：
身高方面：Nancy比Sarah高3cm，Tom比Sarah高10cm，Jack比Tom矮2cm，Tim比Tom高5cm；
体重方面：Nancy比Sarah轻2kg，Tom比Sarah重15kg，Jack比Tom轻5kg，Tim和Tom一样重；
3. 根据这些比较关系，通过简单的加减法计算出每个人的身高和体重，最后填入表格对应的位置。
【解析】
1. 计算身高：
Sarah：短文直接给出为160 cm；
Nancy：比Sarah高3 cm，即160 + 3 = 163 cm；
Tom：比Sarah高10 cm，即160 + 10 = 170 cm；
Jack：比Tom矮2 cm，即170 - 2 = 168 cm；
Tim：比Tom高5 cm，即170 + 5 = 175 cm。
2. 计算体重：
Sarah：短文直接给出为45 kg；
Nancy：比Sarah轻2 kg，即45 - 2 = 43 kg；
Tom：比Sarah重15 kg，即45 + 15 = 60 kg；
Jack：比Tom轻5 kg，即60 - 5 = 55 kg；
Tim：和Tom一样重，即60 kg。
【答案】
1. 160 cm; 163 cm; 170 cm; 168 cm; 175 cm
2. 45 kg; 43 kg; 60 kg; 55 kg; 60 kg
【知识点】
1. 阅读理解细节提取
2. 形容词比较级运用
3. 简单数值计算
【点评】
本题主要考查学生从英语短文中提取细节信息并结合简单数学运算解决问题的能力，需要学生仔细研读文本，准确梳理人物间的身高、体重对比关系，避免因粗心导致计算错误。题目贴近生活，难度适中，能有效锻炼学生的信息整合与计算能力。

首先要明确本次写作的核心要求：运用本单元所学的形容词比较级、最高级描述家庭成员外貌，并进行对比。解题思路可分为五步：第一步，开篇点明家庭成员数量，让读者快速了解写作对象；第二步，分别描述每位家庭成员的基础外貌特征，为后续对比做铺垫；第三步，运用形容词比较级对比家人间的身高、体重差异，这是写作的核心内容；第四步，用形容词最高级突出某一位家庭成员的显著特征；第五步，结尾表达对家庭的喜爱，升华情感。同时要注意比较级和最高级的正确形式，比如tall的比较级是taller，heavy的最高级是heaviest，最高级前需加定冠词the。
【解析】
1. 开篇引入：先用“There are three people in my family. They are my father, my mother and me.”清晰介绍家庭组成，奠定写作基础。
2. 个体外貌描述：分别写出父亲“tall and strong”、母亲“thin and beautiful. She has long hair”的外貌特点，让人物形象更具体。
3. 比较级对比：通过“My father is taller than my mother. My mother is taller than me and she is heavier than me.”将家人的身高、体重进行两两对比，紧扣单元知识点。
4. 最高级突出特征：用“My father is the heaviest in my family.”强调父亲在体重上的最突出特点，丰富对比层次。
5. 结尾抒情：以“This is my family. I love my family very much.”收尾，表达对家庭的喜爱，使短文结构完整。
【答案】
