方法：
1. 原句带was/were的：
否定句==》将was/were改为wasn't/weren't
疑问句==》将was/were和主语互换位置

2. 原句带动词过去式的：
否定句==》加否定助动词didn't后把原动词过去式改为原形
疑问句==》主语前加Did，原动词过去式改为原形

1.The man held out a bag.等这些句子都是一般过去时态，谓语（2以外）都是行为动词，提问或否定要用did，并且要把原来的谓语动词的过去式改为原形

陈述句改疑问句的方法：
1.如果陈述句中的谓语动词是be动词或情态动词，只需把谓语动词提到主语之前即可，最后别忘记加问号。
2.如果陈述句中的谓语动词是行为动词，需根据人称补上一个助动词do/does并将其提到句首，行为动词要变成原型，其他照抄，最后别忘记加问号。
肯定句改否定句的方法：
1.如果肯定句中的谓语动词是be动词或情态动词，只需在谓语动词后加not，其他照抄。
2.如果肯定句中的谓语动词是行为动词，需根据人称补上一个助动词do/does在行为动词之前，行为动词要变成原型，其他照抄。
