As to question number 13:
I wrote: 13)
Öand if they should have also sew or knit, they would soon go to a madhouse, although they might consider it as a hobby.
I think I should have written: Ö.should have sewed or knitÖ, havenít I?
you answered:13) have sewn is correct. It's the present perfect: HAVE + past participle.
!!! My question: I read and learned that past participle of "to sew" is both "sewn" and "sewed". I have been looking for it in my dictionaries and they just say the same.
Does it mean that we can say also "should have sewed" ?
