现在分词一般都按他的规律来走,很少有特殊的、
a)在一般情况下,在动词原形后直接加词尾–ing.
名词变复数
.一般名词复数是在名词后面加上“s”,如map→maps,bag→bags等;
2.以s,sh,ch,x等结尾的词加“es”,如bus→buses,watch→watches等;
3.以辅音字母+y结尾的词,变y为i加es,如baby→babies等;以元音字母+y结尾的名词变复数时,直接加s变复数,如monkey→monkeys,holiday→holidays,storey→storeys(楼层);
4.以o结尾的名词变复数时:
a)加s的名词有:photo→photos,piano→pianos,radio→radios,zoo→zoos
b)加es的名词有:
potato→potatoestomato→tomatoes
5.以f或fe结尾的名词变复数时:
a)加s的名词有:
belief→beliefsroof→roofs
safe→safesgulf→gulfs
b)去掉f,fe加ves的名词有:
half→halvesknife→knives
leaf→leaveswolf→wolves
wife→wiveslife→livesthief→thieves
eg.go–going;do–doing;ask–asking;read---reading
特别要注意:这和第三人称一般现在时的词尾变化不同,动词词尾如为“辅音字母+y”时不变,在其后直接加–ing.
eg.study–studying;carry–carrying;fly–flying;worry–worrying;
b)在以不发音的e结尾的动词后,去掉e,再加-ing.
eg.come–cominglive–livingdance–dancingmake–making
c)在闭音节的单音节动词后、以重读闭音节结尾的多音节动词,而末尾只有一个辅音字母时,将这个辅音字母双写(x除外),然后再加–ing.
sit–sitting;run–running;begin–beginning;forget–forgetting
d)在少数几个以–ie结尾的动词后:须将–ie变作y,再加-ing.(这些动词词典一般均注明)
eg.die–dying;tie–tyinglie–lying
