本文论述了在英语课堂上,学生经常犯的两个语法错误:一、在使用一般现在时,主语是第三人称单数时,经常忘记在谓语动词后加“s”;二、在使用一般现在时势,将系动词be和行为动词同时放在句子中。本文首先假定了这种语法上的误用可以通过某种方式的课堂教学改正,并通过一项为期四周的经过细心规划的课堂实践证实了这一假设。 This article discusses two grammatical mistakes that students often make in the English classroom: First, when using the present-day general subject, when the subject is the third-person singular, it often forget to add “s ” after the predicate verb.

This article first assumes that this grammatical misuse can be corrected in some way by classroom instruction and confirmed by a well-planned classroom practice of four weeks.
