有關現在式既問題想問問

你呢個問題, 本身係有問題既.

首先, 你講既範圍大到以香港黎計, 咁用 "many" 就非常值得商榷, many 即係幾多? 70%? 80%? 90%? 定係其他?

* 而無論幾多個 % 都好, 你又知道全香港有幾多巴人, 有幾多出左去旅行??

*** 所以, 呢的都係無意義既陳述同深究, 簡單用返你果句 There are many people from Islamic Republic of Pakistan. 除非, 你講到全部巴人都被驅逐呢的咁極端既例子.

而如果, 你既例子縮少到一個學校, 一個班級, 甚至一個家庭, 先有深究既意義.

p.s. 英文不過係語言既一種, 無必要太鑽牛角尖.

The simple present is used here in adverb clauses of time and condition,according to your posting.
eg:-The Pakistans will be extradited today when the Authorities act.

eg:-There are many people from Islamic Republic of Pakistan extradite today.
It means, under treaty of foreign fugitive from justic to authorities concerned (=HK--->Pakistan),they are extradited today.

This is an euphemism to substitute of mild terms for blunt one,in this instance Pakistans go to picnic to Pakistan with their alternate ID cards of HKG.
