请记住：清后[t]，元浊[d]，[t] [d]之后读[Id]。
①清辅音[p] [k] [f] [s] [F] 等后，ed要读[t]。
如：worked，finished。
②元音或浊辅音[b] [g] [v] [z] [m]等后，ed要读[d]。
如：lived，called。
③[t]或[d]后，ed读[Id]。

be动词过去式有两种形式，主语是第一、三人称单数形式使用was，其他人称用were。

一般过去时的时间状语应该是表示过去某个时间的词或词组，如：yesterday, last month, in 1999, two days ago等，绝对不可与recently, in the past 10 years, this month等连用，因为这样的时间状语都与现在有关系，应该用现在完成时或一般现在时。
B) used to do的否定形式和疑问形式很特别：你怎么写都正确。
以否定形式为例：used not to do, didn't used to do, didn't use to do都对。
Used to do经常与be used to doing sth/ sth结构进行对比。
前者表示"过去常常或过去曾经"，要求加动词原形；后者表示"习惯于"，要求加名词或动名词。
