1.be- was- were,否定句：was not= wasn't,were not= weren't,一般疑問句把was,were提前到句首
如：I was at home yesterday.
I wasn't at home yesterday.
Were you at home yesterday?
Where were you yesterday?
2 行為動詞：主語+ 過去式
主語+ didn'g + 動詞原形 （ 否定句）
Did+ 主語 + 動詞原形 （ 一般疑問句）
如：I played football yesterday.
I didn't play football yesterday.
Did you play football yesterday.
What did you do yesterday?
3 情態(tài)動詞：如：can
主語 + could +動詞原形
主語+ couldn't + 動詞原形
Could + 主語 + 動詞原形
如：I could swim when I was ten.
I couldn't swim when I was ten.
Could you swim when you were ten?
what could you do when you were ten?
關于一般過去時態(tài),希望對你有所幫助
