问题
选择题
It was at the very beginning____ Mr. Smith made a decision ___we should send for a doctor．
A．what，that
B．that，which
C．which，that
D．that，that
答案
答案：D
题目分析：句意：就在一开始的时候Mr. Smith作出决定，我们派人去请医生。第一个空是强调句型，It is +强调部分+that+其它。第二个空是同位语从句，we should send for a doctor说的就是a decision的内容，此处只能用that起连接作用。故选D。
