　　Verbs ending with a single vowel plus a consonant

　　动词以单元音加辅音结尾

　　If the verb ends with a single vowel plus a consonant, and the stress is at the end of the word (e.g.refer), then you need to double the final consonant before adding -ed and –ing:

　　如果非单音节动词以单元音加辅音结尾，并且重音在最后一个音节，要双写最后一个辅音字母：

动词	过去分词	现在分词
admit 承认	admitted	admitting
commit 犯罪	committed	committing
refer 涉及	referred	referring

　　If the verb ends with a vowel plus a consonant and the stress is not at the end of the word, you don’t need to double the final consonant when adding -ed and -ing:

　　如果非单音节动词以单元音加辅音结尾，但重音不在最后一个音节，则无须双写最后一个辅音字母：

动词	过去分词	现在分词
inherit 继承	inherited	inheriting
target 瞄准	targeted	targeting
visit 拜访	visited	visiting

　　If the verb has only one syllable and ends with a single vowel plus a consonant (e.g. stop), then you need to double the final consonant before adding -ed and -ing:

　　若果单音节动词以单元音加辅音结尾(如stop)，需要双写最后一个辅音字母：

动词	过去分词	现在分词
stop 停止	stopped	stopping
tap 轻敲	tapped	tapping
sob 啜泣	sobbed	sobbing

　　Verbs ending with two vowels plus a consonant

　　动词以双元音加辅音结尾

　　If the verb ends with two vowels plus a consonant, you should generally not double the final consonant:

　　如果动词以双元音加辅音结尾，通常无须双写最后一个辅音字母：

动词	过去分词	现在分词
treat 款待	treated	treating
wheel 转动	wheeled	wheeling
pour 泼	poured	pouring

　　Verbs ending in –c

　　动词以c结尾

　　If the verb ends in -c (e.g. panic), you need to add a -k before adding -ed and -ing, and also -er.

　　如果动词以c结尾，在ed和ing前要加上k，在er前也要如此：

动词	过去分词	现在分词	相关的名词
picnic 野餐	picnicked	picnicking	picnicker 野餐者
mimic 模仿	mimicked	mimicking	mimicker 模仿别人的人
traffic 交易	trafficked	trafficking	trafficker 商人
