Whose 疑问句主要用于询问所有权，即某物或某人属于谁。

在英语中，Whose 疑问句的构成是将 Whose 放在句首，followed by a noun（名词），表示对名词的所有权进行提问。以下是一些 Whose 的问句和答句示例：问句：

1. Whose book is this?

2. Whose car were they in?

3. Whose daughter is she?

4. Whose are these shirts?

5. Whose performance was better?答句：

1. This is my book.

2. They were in Tim's car.

3. She is Tim's daughter.

4. These are Tim's shirts.

5. John's performance was better.在这些示例中，问句用于询问物品或人物的所有者，答句则表示所有权。需要注意的是，Whose 疑问句的回答通常遵循“名词 + 代词”的结构，其中代词可以是形容词性物主代词（如 my，your，his，her 等）或名词性物主代词（如 mine，yours，hers 等）。
