动词ing形式的用法及变化规则
一.口诀:now look listen be,动词要加ing,加了ing,不要忘了be. 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“辅音,元音(a e i o u),辅音"结构的动词,先双写末尾的辅音字母,再加ing 。
这类词有:shop,begin,cut, put, 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ie结尾的动词,把ie改为y ,再加ing 如:die---dying lie-——lying
