present perfect tense 應在什麼時後用?

一般上有兩類過去完成式，對應於兩類完成:

狀態的過去完成式。把某個事件的結果關聯於在過去時敘述期間的這個事件:「He saw that the door had opened, and children were running through it.」 幾乎同於「...He saw that the door was open, and children...」 。狀態的過去完成式，在與這個行動事實的結合上，位於過去時態(the door opened yesterday) 和是過去分詞的表語形容詞(the door was open since yesterday)的中間。

行動的過去完成式。一系列過去完成式句子傳達一個敘述。這種過去完成式更加密切的聯合於英語中平常的過去時態。它只充當把敘述放置於「更遠的過去」中，而不用確定它的特定時間或持續時間，比如:「He had risen early that morning and had drunk coffee earlier than usual.」

例如:I have (done)my homework yet.

你都識講未做就yet啦
咁呢個咪用already囉
同埋already唔一定係好耐之前嫁

而past continuous tense就係講番之前做緊個樣野,而進行時間會比past tense長。例如:I am playing this morning

你都識講past con.
咁你又作個present con.出黎做咩阿?!

小五.唔洗咁串播

p.s.
past con.即係一個長ge past action.同埋已經finished嫁啦

而present perfect.
就係以前開始.岩岩完左

Present Perfect Tense 是當我們剛剛做完的野 可用 have just / have already / not yet

囧= =我小5都識- -present perfect tense 就係你由一段時間做野做到另一段時間,同past tense唔同,past tense就係你好耐之前已經做左,例如:I have (done)my homework yet.姐係我已經做完功課,如果早左好耐既就用already,岩岩做完就用just,未做完用yet.如果題目問Have you (done)your homework yet?做左好耐就答I have( )done my homework already.already,岩岩做完就I have just done my homework.未做完用yet(I haven't done my homework yet.)already可以放係( )個度.佢要用過去分詞(p.p)而past continuous tense就係講番之前做緊個樣野,而進行時間會比past tense長。例如:I am playing this morning(記住+ing因為你之前做緊)I am watching TV when my father call me.(選我最佳啊= -=)
