It was not until early this morning _______ my father came back from work, which surprised us.

A．when

B．where

C．that

D．who

答案

C

解析

试题分析：考查强调句型。本题强调的是时间状语not until early this morning；句意：直到今天早晨早些时候，我的父亲才下班回来，这让我很惊讶。It is/was…that/who…是强调句型的基本结构，故C正确。
点评：强调句型的基本结构为It is/was被强调成分that/who其它成分；其最大的特点就是去掉it is/was…that/who…句子仍然成立。要注意强调句型能强调除谓语动词以为的所有的句子成分。在考查的时候，经常会把强调句型和定语从句结合在一起考查，要注意分析句子的成分。
