蔡英文對外賓説:I have trouble of saying chinese language sometime.請問這句英文有何問題？

I have trouble speaking Chinese (language) sometimes.

.介詞用in或單纯省略，這類名詞有trouble, fun, difficulty 等，所以本句寫法為I have trouble (in)saying--

Error&correction:-
I have trouble of saying Chinese language sometime (x)
I have trouble (in) "speaking Chinese language (on my occasion) sometimes" (o)
I have trouble speaking Chinese language sometimes (in spoken words, not in writing.)
sometimes adv =at some times;now and then; from time to time;eg:-I sometimes have spoken broken Chinese from me (English Tsai蔡英文)(on my occasion) to Americans.
sometime adv,=at some time; eg:-I will speak(on my occasion) to Americans about it(=English Tsai's stuttering stammer蔡英文的結結巴巴說話及口吃) sometime.

蔡英文說的是 I have problem of saying that in Chinese language. 

(我用中文講那個字有點困難。)

蔡英文說的應該是 I have problem of saying that (thing or thinking發音沒完成,或者是 that in 連音）, the Chinese language. I'm sorry. 

say後接單一事件陳述與報導
ex:The weather report says that there will be a storm coming this weekend.

problem可屬名詞，speak表示說某種語言，
I have a problem of speaking Chinese (language).
             or 
I have problems of speaking Chinese(language).

The correct way should be: "I have trouble speaking English sometimes."

刪一刪
I have trouble saying Chinese sometimes.

chinese不用加language......................
