过去式与过去分词的区别?advice可数吗?

动词的过去式用于一般过去时且该动词做句子谓语时;
而动词的过去分词用于其他情况,如被动语态,完成时态,非谓语形式等;
如:do/did/done
1.He did something bad just now.
2.Something bad was done by hime just now.
3.He has/had done something bad.
4.You must have your homework done before tomorrow.
advice是不可数名词.

过去式和过去分词基本形式一样
过去式能做谓语
过去分词可以用在have后或被动（这个大家都知道）
又可以作非谓语（就是指除主语、谓语、宾语）

规则动词的过去式和过去分词是一样的。
比如：stay-stayed-stayed study-studied-studied live-lived-lived等等。
不规则动词中：有些动词的过去式和过去分词是一样的。比如：leave-left-left get-got-got. 有些动词的过去式和过去分词是不一样的。比如：go-went-gone be-was/were-bee...
