你每天在家都干什么
watch 第三人称单数 watches
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,可按名词变复数的规则来记,即：
i）在动词尾直接加 s.如：
play—plays,want—wants,work—works,know—knows,help—helps,get—gets
ii）以字母s、x、ch或o结尾的动词加-es；如：
guess—guesses,fix—fixes,teach—teaches,brush—brushes,go—goes,do—does,watch—watches,catch—catches
iii）以辅音字母＋y结尾的动词,先变y为i,再加-es.如：
study—studies,carry—carries,fly—flies,worry—worries
