以辅音加y结尾的动词，变y为i再加ed:

句型转换解题法：
三问法：
一问有be动词吗？
二问有情态动词吗？
三问动词是什么形式？
详解见下一页：
三问法：
有be动词吗？
有：变否定句，在be后面加not
变一般疑问句，把be提前。
没有，下一问
有情态动词动词(can
will等)
吗？
有：变否定句，在情态动词后面加not
变一般疑问句，把情态动词提前。
没有，下一问
谓语动词是什么形式？
原形：变否定句主语后加don’t；变一般疑问句，主语前面加Do
单三：变否定句主语后加doesn’t；变一般疑问句，主语前面加Does
过去式：变否定句主语后加didn’t
变一般疑问句，主语前面加Did
动词单数和过去式变原形
超重要
Summary:
01：时态辨析看时间状语和谓语动词的状态；
02：考察谓语动词形式的题目：一画关键词定位时态，二确定时态的核心结构。没有关键词，通过翻译法确定动作状态发生的时间。
03：句型转换：采用三问法，避免漏掉关键信息。
一般来说，英语句子大体分为三种，含有be动词的句子，含有情态动词的句子和含有实意动词的句子，从类别角度分析，三问法可以帮助提高句型转换题目的准确率和做题效率。
