有關現在進行式既問題想問問

Leo 你好～
你的句子用現在進行式無問題，但你的發問有問題。

你的句子是
I'm criticizing Mary now.

使用現在進行式 (present continuous tense / present progressive tense)，代表所描述的動詞在說話那時正在進行中（用了 now）。用詞正確，文法無錯。

但你的發問有問題，因為你無故說出一句句子，然後問那句子用某時態有否問題，那其實是沒有意義的，因為句子可以使用不同的時態，如下，也都正確。

Simple Present Tense (簡單現在式)
I criticize Mary every day.

Present Continuous Tense (現在進行式)
I'm criticizing Mary at the moment.

Present Perfect Tense (現在完成式)
I have just criticized Mary.

Past Perfect Tense (過去完成式)
