有關現在完成式的問題

“has allowed” 不是這樣使用. Next Monday 如何?

如果阿爸同意你去海洋公園, 你對 Mary 說
“My dad allows me to go to Ocean Park.“

如果阿爸唔同意,
“My dad doesn’t allow me to go to Ocean Park.”
或
“My dad won’t allow me to go to Ocean Park (next Monday)”
(當 negative 時, 用 won’t 很普遍)

在你的情形, 千萬不要用 present perfect progressive tense

My father has been allowing me to go to Ocean Park ~ dead wrong

The action began in the past. The action is still going on.
知道阿爸從過去某時開始同意,直到現在為止都是同意, 為什麼昨天問阿爸同不同意?
使用 present simple tense OK, 不需要 present perfect progressive tense, 特別是通告

Smoking is not allowed in this restaurant.

在某種情形下, allow 會用 present perfect tense, 但仍然不是 present perfect progressive tense

例子:
The loophole has allowed hundreds of drink-drivers to avoid prosecution.
漏洞允許數百酒後駕駛者避免起訴, 以前開始, 直到現在為止

正如一知識長說過, 為爭分數是無什麼意思, Yahoo 知識網是分享知識

"Mary, my father has allowed me to go to Ocean Park."The present perfect tense is a way of referring to an action in the past ; but whereas past tense refers to a time in the past separated off from the present, the present perfect refers generally to a period of time carried up to the present:-
---eg:-Mary, my father has allowed me to go to Ocean Park (9-8=1) one hour ago.
Present perfect tense:-has allowed=(still allowing it.)

The present perfect progressive tense emphasizes that the action, begun in the past, is still going on:-
eg:-I have been asking father about visiting Ocean Park; he has been allowing for that.
