例句：莉莉有时候在星期六看电影。
Lily

一般现在时的肯定句中，主语为第三人称单数的动词变化主要体现在词尾的变化上，其规律为：
（1）一般情况下，直接在动词词尾+s?。如：
play—plays
write—writes
climb—climbs
拓展：英语动词第三人称单数变化规则
（2）以s,?x,?sh,?ch,?o结尾的动词，在词尾+?es?。如：
guess
—
guesses
fix—fixes
finish
—
finishes?
teach—?teaches
go
—
goes
do?—does?
（3）以辅音字母+?y?结尾的动词，先把y变为i，再加es。
如：study—studies?
try—tries?
fly?—flies?
（4）不规则动词（特殊情况）。
如：?have?—has?
be?—is?
