It强调句-

it强调句

1.it 强调句的结构：

it is/was +被强调部分+that/who（whom）+句子的其它成分

2.句法功能：

对句子中的主语、宾语、表语、同位语、状语等进行强调。

Mary met an old beggar in the street yesterday.

It was Mary who/that met an old beggar in the street yesterday. (强调主语)

It was an old beggar whom/that Mary met in the street yesterday. (强调宾语) It was yesterday that Mary met an old beggar in the street. (强调时间状语) It was in the street that Mary met an old beggar yesterday. (强调地点状语) 3.引导词的运用。

一般来说，只用that进行连接，that没有实际意义，只起语法连接作用。指人时，可以用who/whom(宾格)。

4.时态的运用。

强调句的时态要依原句的时态而定，即原句为过去的某种时态，则强调句中的be动词就为过去式；原句为现在时态，则强调句中的be动词为现在时态。

5.人称和数的运用。

若被强调的部分是主语，则that和who从句中的谓语动词应该和主语保持一致。

6. not...until句式的强调。

与否定词连用的until短语或从句在被强调时应注意否定转移。

I didn`t realize all my mistakes until you told me yesterday.

对主语进行强调：it was I that/who didn`t realize all my mistakes until you told me yesterday.

对状语进行强调：it was not until you told me yesterday that I realized all my mistakes.
