Past tense

Give - gave
Be - was/were/been (depends on your sentence)
Sing - sang
Get - got
Have - had

pass tense : gave , song , get , had　至於ｂｅ，可以唔同解釋如：ｗａｓ，ｗｅｒｅ，ｂｅｅｎ等，睇下佢係配邊個名詞而定．

give - gave / was giving / were giving / given
be - was / were / was being / were being / been
sing - sang / was singing / were singing / sung
get - got / was getting / were getting / getten
have - had / was having / were having / had


視乎你當時情況要用邊個啦...

give-gave
be- was/were
sing-sang
get-got
have-had

希望幫到你.
