Dear friend:
In the following sentence. Does it really make sense? Does anybody know what I mean?
"I went to a primary school of neighborhood this sundown to walk around the playground 20 times as my exercise."
I am afraid nobody know what I mean. If you know what I mean, could you correct the sentence?
I think the sentence is strange to a native english speaker. By the way, In the following phrases, are they all correct?
1. a native english speaker
2. an English native speaker
3. a native speaker of english
4. a speaker of native english
wow! English is really greek to me. I am confused.
Thanks for your help!

Hi.
I'm Spanish speaker but I'd dare to tell you that the correct ones are:
a native speaker of English
English native speaker
or just
English-speaking man

I went to a primary school of the neighborhood at sundown to walk around the playground 20 times as my exercise

I'm not sure whether as my exercise is correct.
