下面是某教师的课堂教学片段：
T: ... Now， let‘s make our own wishes with'if only'. But please don‘t forget to give a description， even though it‘s very brief， of situation， the context， where you make the wish with one or two sentences ... How about Liz?
Liz: Now it‘s 5 o‘clock， and there is a traffic jam on the express way. The hotel will cancel our room at 6 o‘clock if we do not get to the hotel. Then， I‘ll say:Oh， I wish if only I didn‘t go on the journey.
T: Listen， Liz. You see， once you use'I wish'， you don‘t need to use'if only'. Just use either one.
Liz: Yes.
T: So will you try again? Just the wish.
Liz: If only I didn‘t go on the journey.
T: To make it better， you can say'if only I hadn‘t gone on this journey'， because you are already on the way. Go on， please.
