小小問題....

Depends on the contexts

She'd can be
1. She had
She'd died. = She had died.

2. She would
She'd rather dance with you . = She would rather dance with you.

He's can be
1. He is
He's a doctor. = He is a doctor.

2. He has
He's gone = He has gone.

she'd = she had or she would
he's = he is or he has
There is no contraction for "he was".
"他的" = his not he's

he's 可以系"他的"

he's 可能係 he was 的, 不一定係 is
所以我要看看你的問題才可以肯定告訴你啊....
