一般过去时表示过去某个时间里发生的动作或状态，过去习惯性、经常性的动作、行为，过去主语所具备的能力和性格，常常和表示过去的时间状语连用，是一种必须掌握的基础语法。很多人虽然掌握了各个句式，但一说到句式转换就犯了难，然而很多时候我们都会用到句式转换，所以这一次小编就给带来了几个句式转换的小技巧。

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。

eg. 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。

eg.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：

eg. 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+...?

eg. Jack was our headmaster when we were freshman. → Who was our headmaster when we were freshmen?

这几个小技巧大家都学到了没有呢？相信很多人在写作的时候都会先用最简单的陈述句来想，然后再将陈述句改为适合文章内容的句式，而其中最难的就是陈述句变疑问句了，毕竟会涉及到不少的知识，很容易出小错误，所以大家一定要把这几个方法记牢哦。
