I have a question

Why do we use 'daydream' in the present continuous tense?
你的問題未夠詳盡, 沒有指出想知道的是那一點, 不過我嘗試盡量解答：
(1) 'Daydream+ing’ used as a gerund (動名詞)。作「動名詞」的‘daydreaming’是非常普遍的用法, 與網友說daydream是“an action” 又或“daydream continuously”無關。「動名詞」的‘daydreaming’例句有(a) Daydreaming may hinder your studies 發白日夢可能妨礙你的學業；(b) Some psychologists are of the opinion that daydreaming can be constructive in certain aspects, for instance in creative or artistic careers 部份心理學家認為白日夢在某些情況下亦有建設性, 特別是關於講求創造力或藝術性的職業來說。
(2) 'Daydreaming’ as a verb。如果我們說某人在某段時間或某個環境下正在發白日夢, 那當然是用進行式的daydreaming。例如(a) He wasn't listening to you, he was daydreaming then 他沒有留意你說些什麼, 當時他正發白日夢；(b) She is always daydreaming about being a movie star 她時刻都發白日夢, 幻想自己是明星。注意, ‘進行式’ 不一定是present continuous tense, 亦可以是past continuous tense。
........................................
‘Daydream’同時又是名詞(noun), 作名詞的‘daydream’不加 ing。例如 (a) She stared into the distance, apparently lost in a daydream 她凝望遠處, 顯然是迷失在白日夢中；(b) Sometimes daydreams can ease my mind 有時白日夢可以舒緩我的憂慮。

識打中文就咪打英文la-.-

We say daydream is using the present continuos tense, because:

1. 'to daydream' is an action
2. you daydream continuously
3. it is also in the present tense

It is because daydream is a action.When we 講夢哥陣will say what is the deam about that what are you deaming at that moment.



I hope I can help you,you are welcome,no thx!

無得解，因為英文定咗就係定咗!!

It's beause daydream is 進行 時.

Because it is a long action.
One does not daydream just for one second.
But if one is doing this before we use past continous tense.
Can I help you??
