now. This tense is formed with the helping "to be" verb, in the present tense, plus
the present participle of the verb (with an -ing ending):

happening, going on, at some point in the past. This tense is formed with the
helping "to be" verb, in the past tense, plus the present participle of the verb (with
an -ing ending)
EX:HE was
riding my bike all day yesterday
The FUTURE CONTINOUS TENSE indicates continuing action, something that will
be happening, going on, at some point in the future. This tense is formed with
the modal "will" plus "be," plus the present participle of the verb (with an ing ending):
