(Answers may vary.)

【分析】首先观察例句，其运用了“as + 形容词原级 + as + 比较对象”的同级比较结构，解题时需先明确每个句子的比较主体与比较对象，结合物品的实际特征（如大小、重量等），仿照例句的结构选择合适的形容词或短语填空，最后一句需仿照前面的描述，写出符合逻辑的同级比较句子。
【解析】① 笔记本电脑与水瓶相比，水瓶更轻，因此笔记本电脑的重量特征为heavy，故填heavy；② 鼠标的特征是小巧，结合例句结构，填as small as；③ 笔记本电脑与笔记本相比，具有薄或小的特征，故填as thin / small as a notebook；④ 芯片很轻，与叶子相比，符合“as light as”的结构，故填is as light as a leaf；⑤ 仿照前面的描述，可写芯片与沙粒的比较，如The microchip is as small as a grain of sand（答案不唯一）。
【答案】1. heavy 2. as small as 3. as thin / small as a notebook 4. is as light as a leaf；⑤ 示例：The microchip is as small as a grain of sand（Answers may vary.）
【知识点】形容词同级比较（as...as结构）、形容词的用法
【点评】本题结合生活物品考查英语同级比较结构的运用，要求学生结合物品特征和例句结构完成填空，注重基础语法的实际应用，难度适中。
【难度系数】0.6
