Как выбрать время
- Future Continuous: \(will\ be + V_{ing}\) — действие будет идти в конкретный момент будущего. Подсказки: later, this time next week, still.
- Future Perfect: \(will\ have + V_3\) — действие завершится к будущему моменту. Подсказки: by, by the time, already.
- Future Perfect Continuous: \(will\ have\ been + V_{ing}\) — действие будет длиться до будущего момента. Подсказки: by ... for ....
Разбор
- By the end of the month + for three years — важна длительность к будущему моменту, поэтому Future Perfect Continuous.
- later — запланированное действие в будущем, поэтому Future Continuous. By the time we get there + already — к этому моменту она уже уйдёт, поэтому Future Perfect.
- By the end of the century — результат к будущему моменту, Future Perfect. still — процесс всё ещё будет идти, Future Continuous.
