一、如何判断句子中的主语是单数第三人称?
句子中的主语S可以归纳以下三类:
S主语(第三人称)
单个名字 单个人或物 He\\ She\\ It
(如Tina、Paul、Chris等)(如my daddy\\ his mommy\\
your friend\\ the dog\\
a cat\\ the tall tree等等)
二、当句子中的主语S是单数第三人称时,动词单数第三人称形式的变形规律如下:
1.大部分的动词+s , 如run→runs , swim→swims, hop→hops等
2.以ch, sh, o, x, s结尾的动词,必须+ es
如:wash→washes,
teach→teaches, watch→watches, catch→catches
do→does, go→goes
以X, S结尾的动词比较少,只要记住此概念即可。
3.以y结尾的动词,有两种情况
a.动词以y结尾,并且在y字母旁边含有a,e,i,o,u其中一个字母,动词直接+s
如:play→plays (动词中y旁边有a字母)
sway→sways
b.动词以y结尾,并且在y字母旁边不含有a,e,i,o,u其中一个字母,动词必须去掉y+ies
如:fly→flies, cry→cries, (动词中不含有元音字母)
study→studies (动词中含有u, 但是不在y的旁边,必须去y+ies)
