it was my telephone number that miss white happebed to know..为什么用that，强调状语才用that

Question

指物的名词不是用which吗

Answer 1

你可能记错了！英语中的强调句型为it's.....that......（如被强调部分为人，可用who代替that）。此句型可对谓语以外的成分强调。 如：
I met my schoolmate in the street the other day.
It's I who/that met my schoolmate in the street the other day. 强调 I
It's my schoolmate that/who I met in the street the other day. 强调 my schoolmate
It's in the street that I met my schoolmate the other day. 强调 in the street, 不用 where
It's the other day that I met my schoolmate in the street. 强调 the other day 不用 when
理解请采纳！

Answer 2

it was/is ......that....是一种强调句型，把它去掉后，剩余部分仍然成立为一个完整的句子。
