易错句子He chairman the committee every month.
正确表达He chairmans the committee every month.
主语 he 是第三人称单数,一般现在时谓语动词要加 -s;chairman 的第三人称单数是 chairmans。汉语没有主谓一致,容易漏掉 -s。

易错句子Yesterday she chairman the department meeting.
正确表达Yesterday she chairmanned the department meeting.
yesterday 表示过去,谓语要用过去式;chairman 的过去式是 chairmanned,不能沿用原形 chairman。汉语动词没有时态变化,容易忽略。
