“ 1.一般过去时的肯定句就是把谓语动词变成过去式，通常是在规则动词后面加“ed",例如，work--worked,特殊动词要特殊记忆（do--did).例句：he
worked
in
the
factory
last
year.
2.否定句就是谓语原形动词前加"did
not\didn't.例如：he
didn't
work
there.
3.一般疑问句就是在句首加“did",例如：did
he
work
there.
4.特殊疑问句就是在一般疑问句的结构前加上特殊疑问词。例如提问地点,就是：where
did
he
work?但要注意，提问的要是主语就不用助动词did了，如：提问he，就是who
worked
there
last
year?
