一般现在时主语单三人称时的动词变化
①在一般现在时中，当主语为第三人称单数时，动词要用“s”型（即第三人称单数形式）。②所谓动词“s”型的构成，与名词变复数相似，即：
a）在动词尾直接加s。如：playplays，wa
twa
ts，workworks，k
owk
ows，helphelps，getgets
b）以字母s、ss、x、ch、sh或o结尾的动词加es；如：guessguesses，fixfixes，teachteaches，brushbrushes，gogoes，dodoes，watch
watches，catchcatchesc）以辅音字母＋y结尾的动词，先变y为i，再加es。如：
studystudies，carrycarries，flyflies，worryworries
