Presenting the mind-map chart for the PRESENT CONTINUOUS to show how to form it.
Also in boxes the different spelling rules for the -ING form.
Remember the PRESENT CONTINUOUS is used to express:
1) ACTIONS THAT ARE HAPPENING AT THE MOMENT YOU SPEAK, NOW.
I'm reading a post on the blog, now.
2) EXCEPTIONS TO ROUTINES AND HABITS.
I usually go to bed early, but today I'm staying up until late.
3) NEAR FUTURE PLANS.
Next Saturday, I'm meeting my friends at the city centre.
