我想問這句英文點樣寫?

可以寫成 : I am very lucky to find the four leaflet clover.
lucky後面用'for', 係呢到唔係好啱, 而且'find'係動詞, 你呢句便多咗嗰動詞, 係文法上係錯; 如果硬要用'for' , 'find' 便要轉用'finding'。如果你係學生, 最好用啲無mac爭議既英文, 就小啲人哋話你錯。

I have found four leaf grasses very luckily.

應該係:
I am very lucky to find a Clover.

不過你D句都應該得。

應該得 I am extremely lucky for find the four leaflet clover.
應該得 應該得

I am very lucky!I have found the four leaflet clover!
