All teachers received warmest congratulations on Teachers’ Day. They felt ________.A.an honour that they were teachersB.that they were teachers an honourC.it an honour when they were teachers D.it an honour that they were teachers

D解析试题分析：考查it做形式宾语：feel it+adj/n.+ that从句，it是形式宾语，that引导的是真正的宾语从句：句意：所有的老师在教师节都收到最热烈的祝贺，他们感到做老师是一件荣幸的事情。选D。考点：考查it用法点评：在英语中it可以指时间，地点，度量衡等，也可以做形式主语，形式宾语，或者引导强调句型。也可以指代前面提及的同一个人或者事情。要特别模糊it的用法。

我明天再问问老师，叫他解释下这个问题
