我想問下he.she.it.......(20點呀~)

He -use for boy
She-use for girl
it- use for animals OR soild thing OR matter

(在某些宗教上,動物被視為人類,可用he或she,但同樣要根據性性而選用兩者其一)

on- 在上面 eg: A boy stands on chair.
in- 在裹面 eg: We saw a film in the cinema.
at- 可指時間, 那一刻的時間 eg: I will meet at noon.
可指地點 eg: They are waiting Tony at the gate.

of-屬於,比較輕微、不重要的放在 of 前面;反之, 比較有份量、重要的則放於 of 後
eg: The legs of the table OR the hair of ypur body OR the pattern of his trousers
for- 為了 eg: He bought a persent for you.
up- 有向上的位置移動的意思 eg: He picks up a flowers.

from- 由 eg: He came back from china. OR She walked from library to school.
they- 他們or她們or它們or一群人(有男有女),無法從一句句子中判斷性別,要根據前文後理
eg: Nike and Timothy walk out the restaurant. They are laughing.
we- same as 'they' , 但包括自己
eg: Nike, Timothy and I walk out the restaurant. We are laughing.

them- same meaning as'they', 但放在句子最後或中間
eg: I saw them walk out the restaurant.
OR I can't find my keys. I forget where I put them.
were- are的過去式
eg: Nike and Timothy walked out the restaurant. They were laughing.
was- is的過去式
eg: Nike walked out the restaurant. She is laughing.
