二、动词三单形式变化规则
当主语是第三人称单数时,谓语动词需加-s或-es:
规则
动词原形
第三人称单数形式
一般在词尾加-s,(清辅音后读∕s∕,在浊辅音后读∕z∕;在t后读∕ts∕,在d后读∕dz∕。)
play
leave
swim
plays
leaves
swims
以字母s,x,ch,sh,o结尾的词加-es,读∕iz∕,如果动词原形词尾已有e,则只加-s。
pass
fix
teach
wish
do
passes
fixes
teaches
wishes
does
以辅音字母加y结尾的词,先变y为i, 再加-es,读∕z∕。
study
carry
fly
studies
carries
flies
三、☆ 句型转换
1. 否定形式:
①am/is/are+not;
②此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词。
2. 一般疑问句:
①把be动词放于句首;
②用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。
eg. He likes playing football.
He doesn't like playing football.
Does he like playing football?
