时态(Tense)是表示行为、动作和状态在各种时间条件下的动词形式。因此,当我们说时态结构的时候,指的是相应时态下的动词形式。英语时态分为16种:一般现在时、一般过去时、一般将来时、过去将来时时,以及这四者的进行时、完成时和完成进行时。每一种时态都有着与其他时态不同的形式表现和用法,所以在使用时态时需认真注意他们各自的用法,以免错误。对一种时态的学习和掌握对于学习其他时态有帮助作用。本文就以现在进行时态为例,谈谈现在进行时的用法。 Tense is a form of verbs that indicate behavior, movement, and state at various times. Therefore, when we say the temporal structure, we mean the verb form under the corresponding tense. The English tense is divided into 16 types: general present, general past, general future, past, future, and future, as well as when the four are completed, completed and completed. Each tense has its own form and usage different from other tense, so when using tense, it is necessary to pay attention to their respective usage to avoid mistakes. Learning and mastery of one kind of tense is helpful for studying other tense. This article takes the current tense as an example to talk about the current usage.
