Some of mothers who haven't married have thrown their babies without looking after them.

I think if we simply memorize the three forms,present,past,participle is not so good. Probably we need to use it. I put these forms here to let any English Learners,like me,to look up only. The best way is to use it or make an instance ourselves. If I put all the forms,it took me much time. Therefore, I put the forms I often forget.


present past participle

break broke broken

choose chose chosen

drink drank drunk

fly flew flown

forget forgot forgotten

get got got/gotten

hold held held

ring rang rung

run ran run

shine shone shone

show showed showed/shown

swin swam swum


throw threw thrown

wear wore worn


thrown:

He's a young man who's been thrown in jail again and again.

Some of mothers who haven't married have thrown their babies without looking after them. They are not able to help their babies to grow up. That's one of the reasons why they do this kind of cruelty thing. It's one of the problems in our society. I like kids very much,so sometimes I think the children who are thrown are extremely pity.
