`1.` She isn't old enough to drive a car.

`->` Cấu trúc "enough" (với adj):

S + be (not) + adj + enough + (for Sb) + to V

`->` Đủ (không đủ) (với ai) để làm gì 

`2.` I ought to do my chores every day.

`->` S + ought to + V(bare) + O

`->` Ought to = should

`3.` My father is outside the room.

`->` Be not inside = outside: bên ngoài
