The future progressive tense is used when expressing events and action in progress at some future point, however the example sentence cannot be understood in that way.

"Past tense" is used in connection with actions in the past.

The "predicate" is that part that shows the action in the sentence. In Japanese it would be the part that ends in "da", "suru", etc.

The "subject" is the person or object to carry out the action in the sentence. Transformed to Japanese it would be the part that end in "wa" or "ga".
