什么情况下双写加ing

双写的原则是“重读闭音节结尾,末尾只有一个辅音字母。第一是重读音节,第二形式上是辅元辅,辅音+元音字母+辅音字母。如put,set,stop,swim都是单音节的例子;多音节的例子有begin,forget,admit,refer,equip等,都是重读第二音节,而且形式上是辅元辅。 动词加ing作谓语的情况 这时候的动词加ing前面必须加上be动词,形成be+动词ing(现在分词)作句子谓语,构成进行时态句子。 例如: He is reading a book now.他正在看书。 He was watching TV when his mother came in.他妈妈进来时,他正在看电视。 They've been waiting for you for three hours.他们等你三个小时了。 动词加ing做非谓语的情况 1.动词作介词的宾语要加ing(动名词) I'm looking forward to seeing you again.我期盼着再次见到你。 The boy is so excited about hearing from his mother.男孩为收到他妈妈的来信很兴奋。 2.部分动词用动词做宾语,做宾语的动词要加ing(动名词)! I Practising speaking English Every day.我每天练习说英语。 Could you mind opening the door?你介意开门吗? I have finished reading three books.我已经看完三本书。 The old man Enjoys living in the country.这老人喜欢住在农村。 3.一些固定句式后面要加动词ing(现在分词)。 We have fun Playing in the park on Sunday. Most students have problems speaking English. 4.动词修饰名词做后置定语时,要加ing(现在分成)!There is a boy Crying over there. I felt something moving in the house. I heard someone singing in the next room. 5.动词做主语和表语时,动词要加ing(动名词)。 Swimming is very popular in summer. His job is teaching English.

怎样归纳去e加ing和双写加ing的规律?

以-e结尾的动词
(1)如果动词原形以一辅音加一不发音的-e结尾,一般应去掉e再加ing:
write—writing,hope—hoping,care—caring,stare—staring,plane—planing,have—having,save—saving, produce—producing, breathe—breathing
(2)以-ie结尾的动词应先将e去掉,将i变成y然后再加-ing:
die—dying,tie—tying,vie—vying,lie—lying
(3)以-ee,-oe,-ye结尾的动词加-ing时应保留词尾e:
see—seeing,flee—fleeing,free—freeing,agree—agreeing,hoe—hoeing, dye—dyeing,eye—eyeing
(4)以-ue结尾的动词大多应先去e再加-ing:
sue—suing,imbue—imbuing,construe—construing,pursue—pursuing,
rue—ruing
有时,词尾e可去掉也可保留:
glue—gluing或 glueing,cue—cuing或 cueing, blue—blueing或 bluing,
true—truing或trueing,clue—clueing或cluing

以一元音加一辅音结尾的动词
(1)如果动词最后一音节为重读闭音节,最后一个字母需要重复:
run—running, stop—stopping, hop—hopping, plan—planning,star—starring, control—controlling但辅音x是个例外,无需重复(x其实起着两个辅音的作用):tax—taxing,relax—relaxing
(2)如果动词最后一个音节为次重读音节,最后一个字母有时也重复:
kidnap—kidnapping或kidnaping,program—programming或programing
(3)如果动词最后一个音节为非重读音节,最后一个字母大多无需重复:
open—opening,offer—offering,audit—auditing但在有些动词中,重复或不重复均可:
worship—worshiping或 worshipping,focus—focusing或 focussing,cancel—canceling或cancelling,travel—traveling或travelling
以非重读的-el结尾的动词加-ing时,英国英语习惯于重复词尾l,而美国英语则习惯于不重复1。
