happening 为什么不双写n?可不可以详细说明加ing的具体规则?

1.直接加ing do---doing2.以不发音的e结尾的,去e加ing dance--dancing3.以重读闭音节,而且末尾只有一个辅音字母结尾的,双写这个辅音字母,再加ing.get--gettingbegin--beginninghappen不是重读闭音节,重读是ha.很高兴为你解答!多谢你的问题!======以下答案可供参考======供参考答案1:重读闭音节结尾的词才要双写，也就是末尾是“辅音+元音+辅音”的音节，重音还必须在这个音节上。供参考答案2:--------------------------------------------------------------------------------Rule 1: Words ending with a Consonant-Vowel-Consonant Pattern (Review Consonants and Vowels) One-syllable words: ED = If the word ends in a CVC pattern, it gets a double consonant + ED. * note ING = If the word ends in a CVC pattern, it gets a double consonant + ING. * note Examples: ED = RUB > rubbed, STOP > stopped ING = HOP > hopping, SIT > sitting *note: Words ending in w,x,y,z do not follow this rule, simply add ED, or ING Examples: snow > snowed, box > boxing, play > playing Two-syllable words: ED = If the stress is on the first syllable, the word only gets one consonant + ED. ING = If the stress is on the first syllable, the word only gets one consonant + ING. Examples: visit > visited, open > opened happen > happening, enter > enteringED = If the stress is on the second syllable, the word gets a double consonant + ED. ING = If the stress is on the second syllable, the word gets a double consonant + ING. Examples: refer > referred, admit > admitted begin > beginning, permit > permittingConsonants = b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, v, w, x, y, z Vowels = a, e, i, o, u Practice two-syllable ed-ing endings...Rule 2: Words ending in E ED = If the word ends in E, simply add D ING = If the word ends in E, drop the E, add ING Examples: ED = smile > smiled, fine
