区分强调句型和定语从句

第一个 强调句 it was this morning that i saw him in the street.
去掉 it was/that
原句成为This morning,i saw him in the street
结构完整 所以是强调句
第二个 是定从
it was a League meeting that we hold in the club yesterday.
先行词league meeting 在定从中充当主语 用关系代词that/which 不可省略
在做定从练习题中 很容易出现强调句故意来混淆
一般只要开头是it was/is的句子 都要留心下
