Объяснение: Смотри, эти выделеные слова, указывают на время.
В 1 предложении выделено Last week ( на неделе), это указывает на время (Past Simple). В времени есть правильные и неправильные глаголы, можно посмотреть в талице. See является неправильным, поэтому нужное слово записано во второй колонке (saw). Во 2 и 3 Present Perfect. На это указывают for 5 years, since 2005. В этом времени
вс глаголом является Have, Has также глагол с 3 колонки неправильных глаголов. В 4 предложении Present Continuous, к глаголу добавляем окончание ing и вс глаголы am ( для I) , is ( he, she.it), are ( множественное число). В 5 предложении будущее время (Future Simple) есть только вс глагол will.
