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?
