I feit it woud be worth it to see the film.
我覺得這場電影值得去看.
I felt是主句,it would be worth it to see the film是賓語從句
當(dāng)主句用一般過去時,從句的時態(tài)需倒退（即一般現(xiàn)在時變成一般過去時,一般過去時（或現(xiàn)在完成時）變成過去完成時）所以,從句原來的一般將來時It will be worth it to see the film.變?yōu)檫^去將來時It would be worth it to see the film.
be worth it是 值得化費(fèi)時間[精力] 去做某事
It (第一個）為形式賓語（真正的賓語是不定式to see the film)
be worth it 是固定搭配.
to see the film 才是真正的賓語
