()10. classroom is on the second floor, but is on the fifth floor.

A.Our; theirs
B.Ours; their
C.Ours; theirs

10. A

【分析】首先明确物主代词的两类用法：形容词性物主代词（如our）后必须接名词，作定语修饰名词；名词性物主代词（如theirs）相当于名词，可单独使用，无需接名词。第一空后有名词classroom，需用形容词性物主代词修饰；第二空后无名词，需用名词性物主代词作主语。据此分析选项。
【解析】第一空修饰名词classroom，应使用形容词性物主代词our；第二空指代“他们的教室”，且后无名词，需使用名词性物主代词theirs。选项A符合要求；选项B中ours是名词性物主代词，不能接classroom，their是形容词性物主代词，需接名词，不符合第二空；选项C中两个都是名词性物主代词，不符合第一空修饰名词的要求，故选A。
【答案】A
【知识点】物主代词的用法
【点评】本题考查形容词性物主代词与名词性物主代词的区分，属于基础语法考点，需牢记两类物主代词的用法差异。

【分析】
本题考查英语中物主代词的正确使用，核心是区分形容词性物主代词与名词性物主代词的用法：形容词性物主代词（如my、your、our等）后需接名词，在句中作定语；名词性物主代词（如mine、yours、ours等）可单独使用，相当于“形容词性物主代词+名词”。解题时需逐句分析每个代词的修饰对象（后是否有名词）及句子成分，排查误用并修改。
【解析】
1. 原句中mine是名词性物主代词，后接名词phone需用形容词性物主代词my，修改后为：Look! This is my phone. I'm taking a photo of a cat.
2. 原句中you是人称代词，修饰名词bike需用形容词性物主代词your，修改后为：Sam, is it your bike? Its colour is blue.
3. 原句中Hers是名词性物主代词，后接名词eyes需用形容词性物主代词Her，修改后为：Look at the cute cat. Her eyes are green.
4. 第一处：yours是名词性物主代词，后接名词pen需改为形容词性物主代词your；第二处：her是形容词性物主代词，单独使用需改为名词性物主代词hers，修改后为：Hey! It's not your pen. It's hers.
5. 第一处：us是人称代词宾格，修饰名词city需用形容词性物主代词our；第二处：our是形容词性物主代词，作主语需用主格we，修改后为：To make our city more beautiful, we need to plant more trees.
6. 第一处：mine是名词性物主代词，后接名词pen需改为形容词性物主代词my；第二处：your是形容词性物主代词，单独使用需改为名词性物主代词yours，修改后为：Anna, I left my pen at home. Can I use yours?
7. 第一处：you是人称代词，修饰名词schoolbag需用形容词性物主代词your；第二处：my是形容词性物主代词，单独使用需改为名词性物主代词mine；第三处：her是形容词性物主代词，单独使用需改为名词性物主代词hers，修改后为：—Is this your schoolbag? —No, it's not mine. Kate's name is on it. It must be hers.
8. 第一处：we是人称代词主格，修饰名词music teacher需用形容词性物主代词our；第二处：hers是名词性物主代词，后接名词voice需改为形容词性物主代词her；第三处：her是宾格/形容词性物主代词，单独使用需改为名词性物主代词hers，修改后为：This is our music teacher. I like her voice very much. I'm a big fan of hers.
