do的动词变位

词义做，干
级别 A1
变位类型不规则

这个动词的特别之处

在许多时态中不规则——最稳妥的办法是把整张表学下来。 → 不规则动词
要记住的三个基本形式：do – did – done。
第三人称单数的特殊拼写（-es、-ies）：does。 → 一般现在时（Simple Present）

加粗并带下划线的是词尾。◆标出不合规则的形式。

常见陷阱

错误 I am not understanding this sentence.

正确 I do not understand this sentence.

有些学习者学会进行时以后，就到处使用，连状态动词也不放过。“我现在不太明白这句话”里有“现在”，于是写出 I am not understanding this sentence；还有人把 be 和原形混在一起：I am not understand。正确的说法是 I do not understand this sentence。I am knowing 和 I am wanting 在英语母语者听来，比漏掉一个 -ing 更刺耳。

不用进行时的动词（状态动词）
