.Where did you meet the famous actress ? ---It was in the supermarket____we went shopping yesterday

这个问题提得非常好,也是很容易出现混淆的地方,通常我们看到it is/was会优先考虑是不是强调句.强调句的特点是,如果去掉 it is...that将会是完整的句子.如果此处填that ,去掉 it is...that后句子成为we went shopping yesterday in the supermarket.这样的句子不能回答Where did you meet the famous actress 这个问题,所以此处应该选D.
