present simple と present continuous ( BE + ING ) はどう違いますか？説明が難しい場合は、例文を教えて下さい。

Present simple expresses daily, usual habits. Something you do regularly.
For example: I walk to school everyday.
And it mostly comes with a signal such as: everyday, weekly, daily, etc.

Also it expresses facts and general statements, as in: It doesn't snow in my city.

If you are talking about a habit for a male, female or an inanimate, you need to add "s" to the verb.
Example: He speaks fluently.

Present continuous:
Expresses an activity in progress, happening now.
Example: I'm reading my new book.
That means I am reading that book at that moment.


Good luck.
