請幫我改這兩句英文(好簡單的)

I can help you if you speak simple English. 不須用some, 因為(說簡單的英文)是一般性的，所以不是一些。
例如：Dogs cannot fly. BUT NOT (Some dogs cannot fly.)

I don't know the exact location , so I am not sure.

I don't clear the position (沒有正確的動詞, clear 用作動詞是指清理),so I am not sure.

叫佢講一些簡單英文
i can help you if you speak some simple english

I can help if you speak simple English or
I only understand simple English

我想答不清楚這個位置,所以不太肯定
i don't clear the position.,so i am not sure.

I am not sure the exact location / position


其實我好贊同judy的講法, 外國人問路, 應該唔會用字太深, 但係叫佢慢慢講, 應該係:
Excuse me, I can't hear clearly, would you please speak slowly?

i can help you if you speak some simple english ( I can help you if you say yours words more easier and sinpler. )
i don't clear the position.,so i am not sure. ( I can't anwser correct in this position, so I am not really sure )

***Hope I Can Help You***

1. I can help you if you speak some simple english.
2. Sorry, I am not sure the right location.

1. Excause me, can you speak simple english please?

2. Sorry, I am not sure about the location.

ps.其實問路唔會有好難的英文,你叫佢謂慢d可能仲好!
sorry can you speak slower?

I can help you but you must speak a simple english.
Sorry, I am not sure the actually location.
