1) I said: " How much are the courses fees? "

`->` I asked her/him how much the courses fees were.

Câu tường thuật có từ để hỏi (when, where, what, how, why,...) thì sẽ có dạng:

- question + S + V(lùi thì)

2) "I don't want anything to eat these foods", his daughter said.

`->` His daughter said that she didn't want anything to eat those foods.

S + said + ( that) + S + V(lùi thì)

these chuyển thành those.

`1.` I asked how much the courses fees were

S + asked + (O) + question word + S + V_lùi thì

Hiện tại đơn `→` Quá khứ đơn

`2.` His daughter said that she didn't want anything to eat those foods

S + said + (that) + S + V_lùi thì

Hiện tại đơn `→` Quá khứ đơn

these `→` those
