动词原形变第三人称单数的规则一般现在式与发音规律同名词单数变复数大致相同,大多数动词在词尾加“S”大部分可数名词的复数及动词第三人称单数的一般现在式，是以-（e）s结尾的，如：moths，glasses；digs，teaches等。其读法是：
1．在清辅音后发音为[s]。
例：cakes[keɪks]，stops[stɒps]，laughs [lɑ:fs] make－makes [s]
books ['bʊks]
suits [su:ts]
2．在浊辅音及元音后读[ｚ]。
例：girls ['ɡɜ:lz]
pictures ['pɪktʃəz]
potatoes [pə'teɪtəʊz]
reads [ri:dz]
digs [dɪgz]（挖、掘）
cries[kraɪz]
read－reads [z] play－plays[z]
ties [taɪz]
dogs [dɔɡz]
3．在[s]、[z]、[ʃ]、[tʃ]、[dʒ] 、[ з]等音后-es发[iz]。
例：glasses ['glɑ:sɪz]
bridges['brɪdʒiz]
noses [nəʊzɪz]
teaches ['ti:tʃɪz]
washes [wɒʃɪz]
dresses [ 'dresiz ]
blouses [blaʊziz]
以“s, x, ch, sh”结尾的，在词尾加“es”，发音为[iz]
如： teach－teaches [iz]; watch－watches [iz]
4.请注意下面这些词单复数的发音变化：
house [haʊs]
houses[haʊzɪz]
mouth [maʊθ]
mouths[maʊθz]
horse [hɔ:s]
horses['hɔ:sɪz]
5.以辅音字母加“y”结尾的，要先将“y”变为“i”，然后在加“es”读[iz]
如： fly－flies [z]； carry－carries [z] study－studies [z]; worry－worries
6, 以“o”结尾的动词，加“es”，读[z] 如：go－goes [z] do－does [z]
7.下面几个动词变为第三人称单数时，原词的元音部分的发音发生了较大的变化，请注意记忆。 如： 1、do [du:]－does [dz] 2、say [sei]－says [sez]
8.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]
9.词尾se在字母r，l，n后读作/s/。
例：horse [hɔ:s]
nurse [nɜ:s]
worse[英][wɜ:s]
course[英][kɔː(r)s]
universe[英][ˈju:nɪvɜ:s]
pulse[英][pʌls]
else[英][els]
tense[英][tens]
