现在进行时的基本形式是采用动词的现在分词形式，即以动词的-ing形式来表示。

在英语中，动词的现在分词形式可以通过在动词后面加上-ing来实现。

例如，“play”这个动词的现在分词形式就是“playing”。

在句子中，现在进行时通常采用“be动词+现在分词”的形式来表示。

例如，“They are playing basketball now.”（他们现在正在打篮球。

）这句话中，“are playing”就是现在进行时的形式，表达了他们正在打篮球的状态。

现在进行时不仅仅用于表达正在进行的动作，还可以用于表达正在持续的状态。

例如，“The weather is sunny now.”（现在天气晴朗。

）这句话中，“is sunny”就是现在进行时形式，表达了天气正在持续晴朗的状态。

三、一般将来时一般将来时是一种时态，它表示将来发生的动作或状态。
