$37.$ Our grandma used to take care of her younger sisters when she was young.

- used to $+$ $V$ $(Bare)$: Dùng để diễn tả hành động đã xảy ra và kết thúc trong quá khứ, không còn xảy ra ở hiện tại. Nói cách khác là trong quá khứ mình đã từng làm hành động này nhưng bây giờ thì không làm nữa.

$(+)$ S + used to + V (Bare).

$38.$ Tommy is not old enough to drive a car.

$-$ S + to be + (not) + adj + enough + (for sb) + to V: đủ/ không đủ để làm gì.

$39.$ My father has given up smoking for 10 years.

- Thì hiện tại hoàn thành: $(+)$ $S$ + has (I, He, She, It,  Danh từ số ít) $/$ have (We, You, They, Danh từ số nhiều) + V (Pii) +  O

$40.$ Nam is the best person in my class.

- So sánh nhất với tính từ dài: S + tobe + the + most + adj + $($N$)$.

- So sánh nhất với tính từ ngắn: S + tobe + the + adj + “est” + $($N$)$.

- “the best” là dạng so sánh nhất của “good”, không theo quy tắc.
