语 言点讲解：
1.一般过去时：
表示过去发生的动作或存在的状态，也可表示过去经常发生的动作。一般过去时的谓语动词用过去式表示。动词be 的过去式:was . were . 动词的一般过去时在构成否定句和疑问句时必须借助于助动词did .
2. 重用的时间状语：
yeserday , yesterday morning /afternoon /evening 等
a moment ago , two days ago just now 等
last sunday , last year 等
in1991，in the past 等
有时句中没有明确的时间状语，则必须根据上下文的提示来确定:
1）根据问句或答句的时态：
how did you spend your weekend ? i _________(go) swimming
2) 并列连词前后的时态通常一致：
he put on his coat and _________(go) out .
3)短文中起始句对下文有提示作用：
long, long ago , there was a lion and a mouse .
