Answer 1

A)- MARY ENJOYED HER TRIP TO NEW YORK.
B)- I TRIED TO OPEN MY OWN BUSINES LAST YEAR.
C)- HE WASHED HIS HANDS THREE TIMES LAST NIGHT.
D)- I PLAYED  TO MUSIC LAST FRIDAY.
E)- MARIO PLAYED SOCCER LAST SUNDAY.
F)- MY AD WORKED HARD LAST WEEKEND.
G)- I CLEANED MY HOUSE THIS MORNING.  

Answer 2

a - enjoyed
b - tried
c - washed
d - o verbo que vc colocou deve estar errado. Deve ser "to listen", não? Se for como eu deduzi, ficaria assim: listened
e - played
f - worked
g - cleaned


No simple past, basta adicionar um "-ed" no final do verbo. Tem algumas excessões em alguns verbos em que o "y" vira um "i" e tbm em alguns verbos irregulares.
