Thanks LazarH for adding to us. I agree with you that we should write sentences grammatically correct., but we also should increase our academic vocabulary and sentence structure. Thanks.

No, it just depends on how well you're educated. If your educational system was high level, you would speak the language as well and propery. A language just gives a discrbe about yourself. I think we should all keep learning any language grammatically correct, not just a native one. :)
