General: Is she always attentive in class?
Mary will buy you a dictionary,won't she?(tag)
Where were they last week?(special)
The 4th sentence is not correct, if you improve the mistake and write Kate knew English very well, the alternative question will be: Did Kate know English or Italian very well?
She was not cooking dinner at 5 o'clock (negative)
Good luck!
