1、以重读闭音节结尾,末尾只有一个辅音字母的动词,要双写这一辅音字母,再加-ing。例如:run-running, swim-swimming等。
2、以-al,-er,-ill结尾的动词,即使重音不在最后一个音节上,也要双写,再加-ing 如:travelling等。
可以加动词ing的
①及物动词。She likes drawing very much.;
②某些短语动词。 Mary is thinking of going back to New York.;
③ do+限定词(my, some, any, the等)+ -ing,表示“做…事”之意,如:We often do our cleaning on Saturday afternoon. Will you do any shopping on Saturday this afternoon?
④介词:Her sister is good at learning physics.;
⑤形容词worth, busy等:This book is well worth reading. –ing作宾语带有宾语补足语时,要用it作为形式宾语,而将作宾语的-ing后置,如:We found it no good talking like that. Do you think it necessary trying again?
