特殊疑问句:疑问词+be+主语+going to+动词原形?如:What is Jim going to do?

疑问词当主语时:疑问词+be+going to+动词原形?

五、一般过去时

1.一般过去时表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用。一般过去时也表示过去经常或反复发生的动作感谢。

2.Be动词在一般过去时中的变化:

⑴am和is在一般过去时中变为was。(was not=wasn’t)

⑵are在一般过去时中变为were。(were not=weren’t)

⑶带有was或were的句子，其否定、疑问的变化和is,am,are一样，即否定句在was或were后加not，一般疑问句把was或were调到句首。

3.句中没有be动词的一般过去时的句子

否定句:didn’t+动词原形，如:Jim didn’t go home yesterday.

一般疑问句:在句首加did，句子中的动词过去式变回原形。

如:Did Jim go home yesterday?特殊疑问句:

⑴疑问词+did+主语+动词原形?如:What did Jim do yesterday?

⑵疑问词当主语时:疑问词+动词过去式?如:Who went to home yesterday?

动词过去式变化规则:

1.一般在动词末尾加-ed，如:pull-pulled,cook-cooked

2.结尾是e加d，如:taste-tasted

3.末尾只有一个元音字母和一个辅音字母的重读闭音节，应双写末尾的辅音字母，再加-ed，（辅+元+辅）如:stop-stopped

4.以“辅音字母+y”结尾的，变y为i，再加-ed，如:study-studied

5.不规则动词过去式:am,is-was,are-were,do-did,see-saw,say-said,give-gave,get-got,go-went,come-came,have-had,eat-ate,take-took,run-ran,sing-sang,put-put,make-made,read-read,write-wrote,draw-drew,drink-drank,fly-flew,ride-rode,speak-spoke,sweep-swept,swim-swam,sit-sat
