现在时态的定义基于两种基本含义：
状态 (State) (事物是什么, 感觉如何, 或看起来怎样) 和
动作 (Action) (某人做了什么)。
掌握静态动词和动态动词的区别是理解未来所有时态的基础。
The present tense is defined by two fundamental types of meaning: State (what something is, feels, or seems) and Action (what someone does). Mastering the difference between static verbs and dynamic verbs is the foundation of all future tense understanding.
完成本课程后，您将能够：
清晰区分一般现在时、现在进行时和现在完成时。
建立对“时态时间轴”的完整概念理解。
自信地使用适当的时态来描述常规事件和进行复杂的逻辑论证。
By the end of this course, you will be able to:
Clearly distinguish between the Simple Present, Present Continuous, and Present Perfect.
Establish a complete conceptual understanding of the Tense Time Axis.
Confidently use appropriate tenses for both routine description and complex logical arguments.
我们将从复习核心结构（主-谓-宾）和助动词的功能开始。然后，我们将系统地分解一般现在时（状态和习惯）、现在进行时（进行中的动作和未来安排）以及现在完成时（与过去的关联）。每个单元都以实用练习结束。
We will begin by reviewing the core structure (Subject-Verb-Object) and the functions of auxiliary verbs. We will then systematically break down the Simple Present (State and Habit), the Present Continuous (Progress and Future Arrangement), and the Present Perfect (Link to the Past). Each unit concludes with practical application exercises.
