注：在一般过去时的句子中，谓语动词可分为两类一类是be动词，其形式为was与第一、三人称单数连用，were与第二人称和复数人称的主语连用。凡是由be动词做谓语的句子，变否定句时，直接在其后加not,即wasn’t 或weren’t，变一般疑问句将was/ were放在句首，句末用问号。另一类谓语动词是由行为动词来充当，如stayed\went\visited等,这一类动词做谓语时，可与任何人称连用，句子变否定时，要在主语后面，动词的前面加didn’t，动词用原形；一般疑问句是把did提到句首，动词用原形。

三、一般将来时

四、过去将来时
表示过去的某时以后将要发生的动作。但这个"将来"时间绝不会延伸到“现在”；而仅限于“过去时间区域内”。由此可以看出，含这个时态的句子常带一个表示“过去某个时间点”的状语。这个状语或是一个短语，或是一个句子。这个时态常用于：
A）宾语从句或间接引语中；B）表示过去习惯性的动作；C）表示过去情况中的“愿望”、“倾向”，多用于否定句。例如：
A) When I thought about it , I wondered what their reaction would be . 当我考虑这件事时，我想知道他们的反应是什么。
