为什么英语里有的单词后加ing例如 fly+flyingtype为什么typing那个e怎么没了.很

这个要靠背的,通常英文字后面有e,e都会不见英语动词+ing 是进行时如果是动词原型+ing 那就是现在进行时 那个的句式是：be +动词ing 表示正在发生：I'm falling love with him.我爱上他了.如果是动词过去式+ing 那就是过去进行时 这个很少见 表示过去正在发生ing又分为动名词和动词的现在分词两种.在现代语法中不再具体强调其分别的,统一的叫做动词的ing形式.ing形式可以作句子的主语如 Smoking is a bad habit.ing做宾语I like sleeping.ing做定语（多含有主动、正在进行、使得...的含义）The sleeping baby is my son.The exciting news made them break into tears.ing做宾补The result of the test made the student crying.还有好多,建议你可以查下语法书关于非谓语动词和动名词的部分.1.正在进行时中,谓语动词后加ing.如:I'm playing football.2.当动词做主语时,要用动名词,即动词加ing.如:Making salad.3.一些特殊表达.动词后再用动词要用动名词.如:enjoy doing sth.practice doing sth.mind doing sth.finish doing sth.keep doing sth.等下列结构含有ing:1.keep doing2.keep /carry on doing3.keep sb.Doing4.enjoy doing5.finish doing6.be afraid of doing7.be worth doing8.be busy doing9.how about doing//what about doing10.spend some time (in)doing11.spend some money (in) buying12.feel like doing13.stop/keep/prevent … from doing14.thank you for doing15.thanks for doing16.do some cooking/cleaning/reading/shopping/washing17.go swimming/fishing/shopping/skating/boating18.mind/practise doing19.prefer doing … to doing…20.can’t help doing21.there is/are +n.+ doing …======以下答案可供参考======供参考答案1:楼上答的很全拉
