3）以辅音字母+y结尾的动词。先把y改为i,再加es，如:study--studies 4）特殊情况:have--has （二）句型转换:
1）主语为第三人称单数，否定句，在动词前加doesn't，再把动词改回原形。一般疑问句，在句首加does，再把动词改回原形。
回答用:Yes,人称代词+does./No,人称代词+doesn't.如: She has small eyes.
She doesn't have small eyes.
--Does she have small eyes? --Yes, she does./No, she doesn't.
2）主语为除第三人称单数之外的人称，否定句，在动词前加don't。一般疑问句，在句首加do，回答用:Yes, 人称代词+do./ No, 人称代词+don't,如: They have small eyes.
