Ⅳ. Read and choose.(外面下雪啦,Sarah和Sam跟妈妈讨论外出着装,请根据上下文信息,补全对话。)
Sarah: Mum, it's snowing outside. Can I go outside?
Mum: Yes, you can. But it's so cold.
Sarah: Can I wear this sweater?
Mum:
Sarah: Whose coat is this?
Sam:
Sarah:
Sam: They're mine.

A.Whose socks are these?
B.It's our dad's.
C.Yes, but wear a coat too.

C B A

1. 首先分析第一空：Sarah问“Can I wear this sweater?（我能穿这件毛衣吗？）”，妈妈回答应该是同意或者不同意，同时结合后面提到很冷，所以应该是同意穿毛衣但也要穿外套。C选项“Yes, but wear a coat too.（可以，但也要穿一件外套。）”符合语境。
2. 接着看第二空：Sarah问“Whose coat is this?（这是谁的外套？）”，Sam回答应该是关于外套所属的人。B选项“It's our dad's.（它是我们爸爸的。）”符合回答所属关系的语境。
3. 最后看第三空：Sam回答“They're mine.（它们是我的。）”，说明Sarah问的是复数物品的所属关系。A选项“Whose socks are these?（这些是谁的袜子？）”符合语境。
