bạn ak, quá khứ đơn chia làm 3 cách đọc. bn vân dụng vào làm nha.

Những động từ kết thúc :

- d/t+ ed= /id/

- ch/ f/ p/ s/ k/ h+ ed = /t/

-còn lại+ ed = /d/

suy ra:

/t/: visited, looked, watched, worked, painted.

/d/: stayed, played, danced, answered, climbed, listened, loved.

/id/: needed, divided, skated.

bn hãy nhớ thì quá khứ đơn nk

Verbs ending in "id": visited, devided, needed, painted

Verbs ending in "t": watched, looked, worked

Verbs ending in "d": stayed, played, danced, answered, climbed, listened, skated, loved

4 gio 24 phut - 3 gio 50 phut = 34 phút
