这不是所谓的句式杂糅，其实是强调句的省略形式。《张道真英语语法》第509页认为：在口语中强调句中的who, that有时省略。下面的句子均摘自《张道真英语语法》第509页：
I think it was Goethe said this. 我想这话是歌德说的。
It was Pember drove Miss Sophia yesterday, wasn’t it? 昨天是彭伯给索菲娅小姐开车，对吧?
It was you I thought of all the time. 我一直想的是你。
It was then I heard Phuong’s steps. 就在那时，我听到福安的脚步声。
What is it you want me to do? 你要我做的是什么?
Was it in 1980 this happened? 这事是1980年发生的吗?
若不省略则为：
I think it was Goethe (who, that) said this. 我想这话是歌德说的。
