請幫我改這兩句英文

我放工後買了一隻鞋給我丈夫,之後我邀請我朋友到我家唱k,她唱歌好叻,所以我要求她教我點唱歌

I bought my husband(hubby) a pair of shoes after work.
After that, I asked my friend(s) to come over to my place and
sing karaoke with us.
What a songbird she always is!
She sang like a professional singer , so I asked her to teach me how to sing.


Mistakes:

1) after get off duty<--- Mistake

after <======== It is never followed by "get ..."!

After finishING my work. <---------Correct, but clumsy!

2) play karaoke <---------It should be " to sing karaoke".

3) ...so i asked for her teach me how to singing.

I<-------- a capital letter

asked her <--- no " for"

to teach me<---------TO

how to singing<--------------Wrong!

.... ,so I asked her to teach me how to sing. <----Correct now
