Present perfect tense

Grammar rule:
Descriptions:  [Noun | Pronoun] + [have|has] + {past participle} + ...
Questions:  [Have | Has] + [noun | pronoun] + {past participle} + ... + "?"

{past participle}:  Usually add "ed" or "d" at the end of the verb,
but past participle forms of irregular verbs should be resited or
looked up in the dictionary .


Function:
1.  Describe something finished recently.
e.g.  I have just finished my dinner.

2.  Describe something happened just before a current event.
e.g.  He has entered the building when it rains.

3.  Describe the time span of a (finished) event.
e.g.  I have played the violin for over 10 years.
e.g.  I have played the violin since 1990.

Actually, there is one more extra function: implying the action is still maintaining.

eg. I hae played the violin for 10 years.--> Implying that I am still playing now.
But of course, if a relative clause is followed, the meaning can be changed.

Like, I have played the violin for over 10 years. But I find it boring, so I have stopped playing .

Actually there's another tense to present this,
so I don't agree to use it like this.

Should be "I have been playing xxx for xxx" ...

而家既present perfect tense, 可以話同 present perfect continous tense
已經可以話差唔多.
响passive voice 既情況, 個verb change 仲係一樣添~

所以, 呢兩個tense 不無關係

兩個時式當然有關，但以取代的方式使用，
似乎只反映有關人仕不慎重地使用英文。

個標題打了做present prefect.....
