例如：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）注意：it强调句型不能强调句子的谓语。
