working attitude ???

Let me to correct no.2 Mary's working attitude is serious. 瑪莉的工作態度是認真的.
不存在continuous tense. / working 是 [動名詞 gerund]



第一句也不存在[現在進行完成式], 只是說: 瑪莉有一種認真的工作態度.

同意樓上ashleydls 講法.
兩句都係present tense(現在式). 唔係有ing就係continuous tense. 唔係有has/have就係perfect tense.

這裏working是當形容詞用. has 是(有)的現在式,不是perfect tense.

Mary has a serious working attitude. This is correct but this is not present continuous perfect tense. This is a simple present tense. "Working" is a gerund adjective and not a verb. The main verb is "has".

The 2nd sentence is incorrect.

第1句啱,第2句錯
1:mary有(has)嚴謹嘅工作態度
1mary係(is)嚴謹嘅工作態度
人唔可能=工作態度(邏輯嘅名詞,根本唔係物質)
