谓语动词与时态英语中动词有六种变化形式,分别是原形(do),第三人称单数(does),过去式(did),现在分词(doing),不定式(to do)以及过去分词(done),前三者叫谓语动词,后三者叫非谓语动词。一、第三人称单数的变化规则 情态动词没有第三人称单数形式。除了have是特例外,其余的大部分动词,直接在词尾加-s;如果词尾是“ch,sh,s,x,o”的加es;词尾是辅音加y的,改y为i,再加es。Sit_ guess_die_go_ rush_reach_touch_brush_ fly_ copy_say_ run_ do_fix_live_cry_ enjoy_have_ wish_play_ Tie_ teach_buy_study_ drink_go_stay_make_ look_carry_come_watch_plant_fly_do_二、动词ing形式的变化规则一般词尾直接加ing;不发音e结尾的去e,加ing;末尾是“辅元辅”结构的重读音节,要双写最后一个辅音,再加ing;以ie结尾的,改ie为y,再加ingclean_sing_read_walk_take_live_come_have_ like_write_make_skate_dance_cook_swim_run_wash_watch_teach_go_do_ fly_ study_ play_listen_open_ get_ wait_ build_ help_lie_ die_ tie_ see_ be_我们目前需要掌握的时态有一般现在时,一般过去时和现在进行时。判断时态并正确使用动词是重要的考察内容。三、基础练习用所给词的适当形式填空1.He _(get) up at five oclock every morning.2.We often_(play) soccer ball after school.3._you _(brush) your teeth every morning?4.
