1、动词加s和ing的方法动词ing形式的用法及变化规则 二动词现在分词由动词原形在词尾加ing构成,其规则如下: 1)一般情况下直接加ing think-thinking sleep-sleeping study-studying speak-speaking carry-carrying say-saying 2)以不发音的字母e结尾的单词,去掉字母e,再加ing wake-waking make-making come-coming take-taking leave-leaving have-having 3)以重读闭音节结尾,呈现“辅,元,辅”结构的动词,先双写末尾的辅音字母,再加ing
2、 初中学过的这类词有:begin,cut, get, hit, run, set, sit, spit, stop, swim, beg, drop, fit, nod, dig, forget, regret, rid, 等。 visit 不是以重读闭音节结尾,不用双写 travel虽然重读第一音节,词尾音节不重读,但是现在分词仍要双写末尾辅音字母,然后再加ing ,如:travel-travelling.初中阶段此类词只有这一个。 4)以 y 结尾的动词 直接加 ing carry carrying enjoy enjoying 5)以ie结尾的动词,把ie改为y ,再加ing die-d
