　　eg.This is a pencil case.

　　She’S a doctor.

　�、谥覆痪唧w的某個(gè)人或物。

　　eg.I met an old man On my way home.

　　③用在序數(shù)詞前，相當(dāng)于another。

　　eg.There’s a third boy near the shop.

　　④表示“每—(個(gè))”，相當(dāng)于every。

　　eg.They have music lessons twice a week.

　　He left in such a hurry that he forgot to close the door.

　　What a dangerous job it is!
