    The earliest telephones required a different pair of wires for each phone ___ you wished to connect.

    A.that

    B.which

    C.where
    D.to which

    答案：D
    解析：
    本题考察定语从句。题目意为“最早的电话需要一对不同的线路分别给本机和想要接通的电话。”本题是介词+关系代词形式，connect表示连接二者时，需要介词，connect sb/sth with/to sth。关系代词which在定语从句中作介词的宾语时,可以跟介词一起放在主句和从句之间，这时的关系代词不能省略;有时为了使关系代词紧跟它所修饰的先行词,也可以把介词放在从句中有关动词的后面,这时的which可用that替换。
