簡單英文文法

(In) is a perposition. It uses before the place (Hong Kong) . So the correct one is I work in Hong Kong. The wrong one is I work Hong Kong.

I work in hong kong
這句譯為我在香港工作。( It is a complelety sentence)


I work Hong Kong
這句譯為我香港工作。(It is not a completely sentence)

一句句子應有ｐｒｅｐｏｓｉｔｉｏｎｓ,第一句correct

I work in hong kong correct!!!!

I work in hong kong - correct

第一句正確。
第二句欠了preposition。

第一句對!!
