（3）以“辅音字母加 - y”结尾的动词，要先变y为i再加-es. 　　try---tries study---studies cry---cries fly---flies 　　
2.不规则变化： 　　be---- is have----has

第三人称单数，he，she，it
人名：Mary , Tom, Tony, Mike
谁的谁：my father，your mother, his sister, our teacher
可数名词单数：a horse, this book, the moon, the earth
不可数名词：water, paper, time, money
非谓语：to do , doing 等，
时态是一般现在时时，动词应用第三人称单数形式。
四、一般现在时的句子转换：
　　
（1）当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等等)提到主语的前面变成疑问句;在be动词或情态动词后面加not变成否定句. 　　
例：
①陈述句：She is a student. 　疑问句→ Is she a student 　否定句→ She is not a student.
　　
②陈述句：I can swim. 　疑问句→ Can you swim 　否定句→ I can not swim. 　　
（2） 当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do (you,以及复数), does（单数she,he,it）变成问句；在主语后谓语动词前加助动词don’t（I,you,以及复数), doesn’t（单数she,he,it）变成否定句，助动词后的动词要变成动词原形。 例：
①陈述句：We get up at 7:00 every morning. 　疑问句→Do you get up at 7:00 every morning 　否定句→We don’t get up at 7:00 every morning.
　　
②陈述句：She has a little brother. 　疑问句→ Does she have a little brother 　否定句→ She doesn’t have a little brother.
