student.
②单个人名(如MikeAmy等)、地名(如Beijing等)、称呼(如

WangMiss Li等)作主语,是第三人称单数。

Uncle Li is a
teacher.
③单数可数名词或“thisthatthe+单数可数名词”作主语时,是
第三人称单数。如:(this manthat womanthis boythat girlthe
manthe studentthe bookthe cat)
This man is
my father.
That boy is my friend.
The book
is red.
The cat is so fat.

“I”is a letter(字母)。
