规则变化遵循以下原则.docx

规则变化遵循以下原则：
一般情况下，在动词后加 ed 构成：work / worked, stay / stayed, shout / shouted 等。
在以-e 结尾动词后只加 d： close / closed, like / liked, live / lived, smile / smiled 等。
以辅音字母加y结尾的动词，应将y改为i再加-ed : study / studied, carry / carried 等。
以重读闭音节或r音节结尾且末尾只有一个辅音字母动词，要双写末尾的
辅音字母再加 -ed : stop / stopped, admit / admitted, refer / referred, prefer / preferred 等。
