Question

英语什么情况下才双写最后的单词再加ing?

Answer 1

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?

Answer 2

如果这个单词最后一个字母是辅音，而它前面有一个且只有一个双元音（a e i o u）这种情况下要双写。
