英文文法問題

所謂 has had，只係 present perfect tense，但係 has 同佢自己o既 past participle 走埋一齊嚇你一跳o者。
present perfect 其實都係講過去左o既事，但係：

present perfect 唔會講發生時間，通常只係 simple past會講
present perfect 用於講剛發生o既事
present perfect 講o既事發生左之後，同現在仍有密切關係，效果持續
如：I've broken my leg. 意思可以係 I broke my leg last week. 但依家呢？斷腳一日未好返，都仲可以用 I've broken my leg.
如果今日你買左架車，你可以講 I have a car.　咁係講現狀（你有車），所以用 simple present。
點解？因為你買囉，所以可以話 I have bought a car. 你剛買左，發生冇耐，可以用 present perfect，而買左之後你就擁有佢架啦。一年後，你可以同人講：
I have had this car for one year. 我已經擁有呢架車一年啦。

When the verb is have and the tense is in present perfect, you can use has had.
For example, You have just had your lunch.
