三单动词变化及读音

动词三单变化规律（只有一般现在时才有第三人称单数）动词好好看，词尾有变幻，规律掌握好，一点都不难。

1.一般在词尾加s:

eats drinks sleeps sees looks hears walk talk reads writes 2. 词尾读音“是稀奇”，就加es：

kisses misses fixes dresses stresses presses expresses impresse s washes brushes pushes flashes teaches watches matches

3.单词结尾y，千万别乱猜，元加y就不改，直接加s，辅音加y，改y为i加es:

stay pay play buy say enjoy destroy display spray slay

study--studies carry –carries marry—marries worry—worries hurry —hurries fly--flies try--tries dry—dries cry—cries bury--buries

4.记住特殊的两个单词go和do后面加es：

goes does

5.记住最为特别的be的三单是is; have的三单是has.

动词第三人称单数词尾变化有三种形式。

(1)一般动词在词尾加-s，-s在清辅音后读／s／，在浊辅音或元音后读／z／，ds读／dz／，ts读／ts／。如：

help→helps／helps／，know→knows／nEuz／，get→gets／gets／，read→r eads／ri:dz／

(2)以字母s，x，ch，sh或有些以o结尾的动词加-es，-es读／iz／。如：guess→guesses／'gAsiz／，fix→fixes／'fiksiz／，teach→teaches／'ti: tFiz／，wash→washes／'wRFiz／

注意：go→goes／gEuz／，do→does／dQz／

(3)以辅音字母+y结尾的动词，先变y为i，再加-es，-ies读／iz／。如：carry→carries／'kAriz／，fly→flies／flaiz／

注：在play→plays／pleiz／，say→says／sez／中，字母y前为元音字母，第三人称单数形式直接在动词后面加-s。

(4)特殊词例外。如：

be→is，have→has
