初中英语语法一般过去时知识点总结归纳表示过去发生的动作或事件，常和表示过去的时间状语连用，如yesterday, last night, the day before yesterday, 3 days ago.含有be动词的句子，将be动词变为过去式。am, is的过去式为was, are的过去式为were：I was at the butchers.You were a student a year ago.The teacher was very beautiful ten years ago.变否定句在be动词后面加notI was not at the butchers.You were not a student a year ago.The teacher was not very beautiful ten years ago.变疑问句将be动词移动到句首Were you at the butchers?Were you a student a year
