Mình gửi thêm bạn vài công thức:

* Cấu trúc TOO:

S + be + too + adj ( for S.O ) + to V : Cái gì quá ...đến mức....

* So sánh hơn :

S + tobe + more/ adj - er + than +... 

- Với slow có thể là slowlier hoặc là slowly luôn nha

* Cấu trúc take / spend :

TAKE : It takes + S.O + Time + to do S.thing : Nó chiếm của bạn bao nhiêu thời 
gian để làm ....

SPEND : S + spend ( s/o ) + time + V-ing : Ai đó dành bao nhiêu thời gian để làm..
( cái này mình thêm thôi )

* Have to :
Have to ở khẳng định : Là sự khách quan -->sự bắt buột , phải làm ( dùng trong cái luật , nội quy ..)

Have to ở phủ định : Là sự chủ quan --> làm cũng được không làm cũng được

* Used to / be used to / get used to :

Be used to : đã quen với           + V-ing

Used to : đã từng                      + V -inf

Get used to : dần quen với       + V-ing
