动词的现在分词的变化规则 1、一般不及物动词的现在分词的构成:一般动词的现在分词是动词原形在加上 -ing 构成的。同理,不及物动词的现在分词也是动词原形后加 -ing 构成的。例如:lie→lying,sit→sitting,swim→swimming。 2、以不及物动词 be、have、do 为特殊讨论: (1)be现在分词形式是being。 e.g. He is being punished for his mistake. (2)have现在分词形式是having。 e.g. She is having a rest. 。 (3)do现在分词形式有doing、done两种,它们的用法不同: ①doing表示不及物动词,也可用于及物动词的被动语态。 e.g.。 (1) He is doing his homework. 。 (2) The book was doing well. 。 ②done可以像一般动词一样用于及物动词的被动语态。 e.g. The book has been done. 3、不及物动词的现在分词的拼写变化: (1)以不及物动词e结尾的,现在分词一般以-ing构成,如:run→running, ride→riding. (3)以元音字母+y结尾的,改y为i,现在分词以-ing构成,如:stay→staying, play→playing. (4)以辅音字母+y结尾的,现在分词以-ying构成,如:study→studying, carry→carrying. 本文来源:https://www.wddqw.com/doc/69eff4a0740bf78a6529647d27284b73f3423676.html
