英文問題-請幫忙解答

I have something to do or have to do something是對的?
Both are correct but with different meaning.
I have something to do = Sorry I am busy.
例句: Sorry, I can't accompany you for shopping this afternoon as I have somethig to do.
I have to do something = something must be done.
例句: My son is betting on ball games recently, I have to do something about it.
Hope you can understand.

I have something to do這句的have是主動詞，是”有”的意思，全句意思是：
我有些事情要辦
而I have to do something這句，have to是情態動詞（mordal verb)意思是：必須、不得不
全句的意思是：我不得不辦些事去
希望幫到你！

I have something to do
or
I have to do something
都是對的, 只是解釋不一樣
I have something to do 解作:- 我有一些事情要做
I have to do something 解作:- 我一定要做一些事來
