Answer 1

1 包含was或者were，用wasn't或者weren't；

They weren't happy at all that day.
2 不包含was或were的，用didn't，然后将句中的动词恢复为动词原形形式。
I didn't go to the park yesterday.

实义动词：didn't +动词原形（把原来的过去式改为动词原形）
was/were: 改为：wasn't/weren't.如：
He went to school yesterday.-He didn't go to school yesterday.
He was at home yesterday.-He wasn't at home yesterday.

Answer 3

----- I was a student. ---- I was not a student.(be动词）
-----I went home. ----- I didn't go home.（实意动词）

Answer 4

was -wasn't
did- didn't
