　　语法 Grammar in use

　　1.以疑问词 whose 引导的特殊疑问句

　　(1)用来询问所有关系。所有者总是一个人而且期望得到的回答是某人的名字加-'s形式(如 Tim's蒂姆的)，或者是一个所有格代词(如 mine我的)。

　　(2)这时 whose 也可在句子中作表语。

　　(3)当所有关系中指的是某件东西或某种物质时，whose后面的名词可以省略。

　　2.所有格形容词和所有格代词

　　(1)所有格形容词与所有格代词都表示所有，即某人或某物属于某一个人，回答以whose引导的问句。所有格形容词my，your等是限定词，必须始终放在名词之前，只能作定语。它们的形式取决于所有者，而不是被拥有的东西。所有格代词mine，yours等不能用在名词前，并且在说话时要加重语气。它们指人或物，单数或复数都一样。如：

　　This is my car.

　　这是我的汽车。(定语)

　　That is her coat.

　　这是她的上衣。(定语)

　　Your car is red，mine is blue.

　　你的车是红色的，我的是蓝色的。(主语)

　　This book is his，not yours. 这本书是他的，不是你的。(表语)

　　I have my way, and she has hers. 我有我的处事方式，她有她的。(宾语)

　　(2)名词所有格是在词尾加-'s构成的，不仅可作定语，还可作表语：

　　Is this Dave's shirt?

　　这是戴夫的衬衫吗?(作定语)

　　Whose is that shirt? Is it your daughter's?

　　那条裙子是谁的?是你女儿的吗?(作表语)
