单词变名词的一般规则

ads


一、动词的三单变化


单就是he,she,it;以及可以用he,she,it代替的名词。】

当主语为第三人称单数(he, she, it)时,要在动词后加"-s"或"-es"。如:Mary likes Chinese.玛丽喜欢汉语。

动词+s的变化规则

1.一般情况下,直接加-s,如:cook-cooks, milk-milks

2.以s. x. sh. ch. o结尾,加-es,如:guess-guesses, wash-washes, watch-watches, go-goes

3.以“辅音字母+y”结尾,变y为i, 再加-es,如:study-studies

二、名词的复数变化


名词复数的规则变化是:

①一般在词尾加“s”如:desk+s [-ks]  bag+s [-gz] bed+s[-dz] hat+s [-ts]

②以字母 s、x、sh、ch结尾的名词变复数,通常在词尾加“es”,如:bus+es [-iz] box+es [-iz] brush+es [-iz] watch + es [-iz]

③以字母o结尾的名词变复数, 一般在词尾加“s”,也有加es的,如:photo+s [-z]  tomato+es [-z] 

④以f或fe结尾的名词一般变f或fe为v再加es,例如:

knife─knives[-vz]  leaf─leaves [-vz]

⑤以"辅音字母+y"结尾的名词,变复数时改y为i,再加es, 如: baby ─ babies  factory─factories

sheep ─ sheep


注意:某些名词只有复数形式,例如:people (人们) clothes (衣服) trousers (裤子) police (警察) glasses (眼镜)

动词的单数第三人称变化规则




规则一般情况词尾直接加s

e.g. like—likes, look--looks, get--gets


规则o, s, x, ch, sh结尾es

e.g. go--goes, do--does, pass--passes, fix--fixes, catch--catches, wash--washes


规则以辅音字母+y结尾yi再加es

e.g. carry—carries, fly--flies


规则4 以元音字母+y结尾直接加s

e.g. play--plays, stay--stays, pay--pays, buy--buys


规则5 不规则变化

e.g. have--has



动词的单数第三人称发音规律



大多数动词在词尾加“S”在清辅音后发音为[s],在浊辅音及元音后发音为[z]如:

stop-stops [s] ; make-makes [s]

read-reads [z] ; play-plays [z]


以辅音字母加“y”结尾的,要先将“y”变为“i”,然后在加“es”[iz] 如:

fly-flies [z]; carry-carries [z]

study-studies [z]; worry-worries


“s, x, ch, sh”结尾的,在词尾加“es”,发音为[iz]。 如:

teach-teaches [iz]; watch-watches [iz]


“o”结尾的动词,加“es”,读[z] 。如:

go-goes [z] do-does [z]


以不发音字母“e”结尾的开音节词,如果尾音是[s][z]时,加“s”后字母“e”发音,与所加“s”一起读做[iz]。 如:

close-closes [iz]


下面几个动词变为单数时,原词的元音部分的发音发生了较大的变化,请注意记忆。如:

1do [du:]-does [dz]

2say [sei]-says [sez]
