  一般过去时三种变化技巧
 
  一变:肯定句变为否定句
 
  【技巧1】当句中含有情态动词或助动词could,would,should等时,可直接在其后面加not构成否定句。例如:
 
  I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
 
  【技巧2】当句中含有系动词was,were 时,可直接在其后加not构成否定句。例如:
 
  I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.
 
  【技巧3】当句中谓语是除情态动词、助动词、系动词was,were以外的动词时,在该动词之前加did not / didn't,动词还原,构成否定句。例如:
 
  The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.
 
  二变:陈述句变为一般疑问句
 
  【技巧1】移动词语的位置。将was,were,could,would,should等移到句首。例如:
 
  He could pack his things himself. → Could he pack his things himself?
 
  【技巧2】添加助动词did。谓语是除情态动词、助动词、系动词was,were以外的动词时,在主语之前加did,动词还原。例如:
 
  Mr Li looked very old. → Did Mr Li look very old?
 
  三变:陈述句变为特殊疑问句
 
  【技巧1】确定疑问词:人who / whom,物what,地点where,时间when / what time,原因why,频率how often,长度how long,距离how far等等。例如:
 
  They gave the concert last night. → When did they give the concert?
 
  【技巧2】辨认结构形式:疑问词+情态动词/助动词/ was / were / did +主语+...? 例如:
 
  The accident happened near the station. → Where did the accident happen.
