一般过去时的句型互换技巧

一：陈述句变为一般疑问句

1、移动词语的位置。将was，were，could，would，should等移到句首。

例句：The baby could eat dinner by himself。→ Could the baby eat dinner by himself？

2、添加助动词did。当谓语是普通的实义动词时，在主语之前加did，动词用原形。

例句：She went to cinema。→ Did She go to cinema？

二：陈述句变为特殊疑问句

1、疑问词提前，动词还原：

例句：They had party last night。 → When did they have party？

2、套结构：疑问词+情态动词/助动词/ was / were / did+主语+……？

例句：Jack was our headmaster when we were freshman。 → Who was our headmaster when we were freshmen？
