语法 Grammar in use
一般现在时与现在进行时
一般现在时表示一般的动作或不断重复发生的动作；现在进行时表示说话时正在发生的动作，动作还没有完成。
一般现在时表示永久的情况；进行时表示暂时的情况。
进行时只用于表示动作或偶尔发生的事件（We are eating, it is raining等等）。有些动词（如 like, want, know等）不是动作动词，因此不能用进行时态，如不能说 I am knowing或We are liking，而只能说 I know或 We like。
一般现在时表达某个习惯性动作，通常与时间频度副词连用，如 usually, always, often, sometimes, never等；现在进行时表示此时此刻正在进行的动作，一般与 now, at the moment, today, this afternoon, this evening, tonight等连用。
We usually watch television at night. But we are listening to the stereo tonight.
我们通常晚上看电视。但是今晚我们正在听立体声节目。

一般现在时和现在进行时是英语中两种非常重要的时态，它们各自有不同的用法和特点。
一般现在时用于描述习惯性的动作、规律性的行为、普遍真理、永恒的现象以及状态。这种时态通常与表示频率的副词连用，如 usually, always, often, sometimes, never 等。例如：
此外，一般现在时也用于描述当前存在的状态，尤其是与 be 动词连用时。例如：
现在进行时则用于描述正在进行中的动作或事件，特别是说话时刻正在发生的事情。这种时态由 be 动词（am/is/are）加上动词的现在分词（-ing 形式）构成。例如：
现在进行时常与表示当前时刻的副词或短语连用，如 now, at the moment, today, this afternoon, this evening, tonight 等。例如：
需要注意的是，有些动词如 like, want, know 等，它们不是动作动词，而是状态动词或感官动词，因此它们通常不用现在进行时态。相反，我们会使用一般现在时来表达这些状态。例如：
通过理解一般现在时和现在进行时的不同用法，我们可以更准确地表达我们的意思，使语言更加丰富和精确。
