или will help или will be helping (если будущее время)

Объяснение:

Нужно смотреть по контексту, если есть слова bow, at the moment, то is helping, а если usually, sometimes, always то helps

точно так же само с остальными временами, если написанно yesterday, last year то то helped, если указано точное время в то was helping. Если написано tomorrow, the day after tomorrow, то will help, если указано точное время в будущем, то will be helping.
