23、示过去发生的事;b e用w a s或用w e r e,h a v e,h a s变h a d;谓语动词过去式,过去时间作标志;一般动词加-e d,若是特殊得硬记。否定句很简单,主语之后d i d n t添;疑问句也不难,d i d放在主语前;J 不含b e动词时如果谓语之前有d i d,谓语动词需还原;动词若是was,were,否定就把no t添。含be动词时疑问句也不难,要把was,were放在主语前。二、b e的一般过去时:学习动词b e的一般过去时,下面有一口诀,它可以帮你们更好地掌握动词b e的一般过去时。b e的过去时有四巧:一是时间状语巧,表示过去的短语要记牢;二是形式巧,单数w
24、a s,复数w e r e;三巧是否定句结构,n o t紧跟w a s /w e r e;四是疑问句式巧,w a s /w e r e向前跑(提前)。【一巧】时间状语(即标志词)巧。一般过去时表示过去发生的动作或存在的状态,恰巧与表示过去的一些时间状语连用。1 .yesterday 或以其构成的短语:y e s t e r d a y m o r n i n g(a f t e r n o o n,e v e n i n g)等;2 .由“last+一时间名词”构成的短语:l a s t n i g h t,l a s t ye a r (wi n t e r,m o n t h,we e k
25、)等;3 .由“时间段+ago”构成的短语:a m o m e n t a g o,a s h o r t t i m e a g o,a n h o u r a g o 等;4 .其它:just now 等5 .由某些表示过去时态的从句等。【二巧】形式巧。它与一般现在时一样,形式多样:当主语是第一人称单数或第三人称单数时,谓语动词用wa s;主语是第二人称或其他人称复数时,谓语动词用we r e。例如:I wa s i n t h e c l a s s r o o m ye s t e r d a y m o r n i n g.昨天早上我在教室里。H e wa s a t s c h o
