we first heard of the man referred to as a computer specialist in software．

A. It was Hilary that

B. That it was from Hilary

C. It was from Hilary whom

D. It was from Hilary that

答案：

A. It was Hilary that

B. That it was from Hilary

C. It was from Hilary whom

(答案→)D. It was from Hilary that

解析：考查强调句型。It is... that...是强调句型，意为“正是......”，可以强调除了谓语之外的任何成分。强调人时，可以用who/that，强调物只能用that。句意“我们是从Hilary那里第一次听说的，那个人是一家如那件公司的电脑专家。”本句强调的是 from Hilary，而不是强调人。故选D。
