七年级英语 实义动词用法
现在我们学的实义动词分动词的原形和第三人称单数形式。当主语是第三人称单数时,我们用动词的第三人称单数形式.其他的人称用动词原形. 人称有第一人称 I （我）, we (我们）,第二人称you (你)， you （你们）,其他都是第三人称。第三人称分单数(如：he/ she/ it/ that/ the pen / Tom…）和复数(they/ these/ my parents…）.
我们已经学过的实义动词的第三人称单数形式变化:
(1) 直接加s。
eg: ask—asks like-likes speak-speaks help—helps take/takes think-thinks
get—gets eat—eats want—wants
find—finds call—calls love—loves play—plays spell-spells sound-sounds
see—sees say-says know— knows come—comes run—runs
read—reads sing—sings swim-swims dance-dances buy/buys
(2) 以字母s， x， sh, ch结尾的加es。 eg： watch-watches teach-teaches
(3) 以辅音字母=y结尾的变y为i, 再加es. eg: study-studies
(4) 不规则动词。 eg: do-does go-goes have-has
