英语语法大全--一般过去式的各种变法（否定,疑问句） [No. 1]否定句的变化：
含有be动词的过去时,变否定句在was和were的后面加not.was not与were not可缩写成wasn’t和weren’t.如：
They were here last week.
→They weren’t here last week.
含有行为动词的过去时,变否定句要借助助动词do/ does的过去式did,在did后加not放在主语后,并把行为动词恢复原形.如：
He did his homework last night.
→He didn’t do his homework last night.[No. 2]一般疑问句的变化：
含有be动词的过去时,变一般疑问句把was/were提到句首,要求首字母要大写.如：
They were at home last night.
含有行为动词的过去时,变一般疑问句要借助助动词do/ does的过去式did,把did放句首,行为动词也要恢复原形.如：
He listened to the radio yesterday.
→Did he listen to the radio yesterday?[No. 3]特殊疑问句的变化：
含有be动词的过去时,变特殊疑问句是先根据画线部分确定特殊疑问句,再把was/were提到主语前构成一般疑问句,并放在疑问词后.如：
My weekend was great.
含有行为动词的过去时,变特殊疑问句同样是先根据画线部分确定特殊疑问词,再借用助动词did构成一般疑问句,（行为动词恢复原形）,并放在疑问词后.如：
I went to Beijing last week.
→Where did you go last week?巩固练习：
