除了I (我) 和 you (你) 之外, 如果用 present simple tense, singular subject (單數主詞) 任何英文字(單數), 當用main verb (動詞) 都係要加s.
Verb 字尾如果是ch, sh, ss, x, z 要加 es.
第3身(單數): he, she, it, Tom, Mary, boy, girl, teacher, dog, book, …. etc.
He reads a book.
He washes the dishes.
Mary passes the shop.
He fixes the car.
The dog barks.
小心 subject 是plural, (made up of two singular noun)
Tom and Mary wash the dishes. 不用 washes.
字 news, mathematics, physics, statistics 是 singular noun, 雖然字尾是s
The news surprises me. (news是 third person singular)
Physics is a difficult subject.
My friend, My behaviour 是第3身單數. "My" is the possessive form of "I".
My friend reads a book.
My behaviour shocks my parents.
