求动词什么情况下加ing时，前面的字母要双

Question

如题所述

Answer 1

动词 加ing时双写的情况如下：
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：begin-beginning, beg-begging, cut-cutting, get-getting; drop-dropping,
run-running, swim-swimming, set-setting , sit–sitting, stop-stopping, put–putting,
hit-hitting ； stop-stopping
动词原形要变ing 一般是因为，
1） 动词原形在句中变现在进行时 ，其结构是 be+Ving
2） 动词在句中要用动名词表示。 是 V+ ing
3） 有些特殊的词组和表达，比如
be good at doing sth. , do some cooking/cleaning/shopping/ washing/reading ;
enjoy doing sth, be busy doing sth , thank you for doing sth,
