Giải thích

Áp dụng cấu trúc wish ở hiện tại , ta có

`(+)` S + wish(es) + (that) + S + V-ed

`(-)` S + wish(es) + (that) + S + not + V-ed

`->` If only : If only + (that) + S + (not) + V-ed

Áp dụng cấu trúc wish ở quá khứ , ta có

`(+)` S + wish(es) + (that) + S + had + V3

`(-)` S + wish(es) + (that) + S + had not + V3

`->` If only : If only + (that) + S + had (not) + V3
