About English sentence expansion.

am reading同is watching係present continous tense，即係現在進行式。而且你都可以改為while i am reading a story book,she is watching TV.。避免用and咁沉氣。當然，佢地都係verb啦。

story本身唔係adjective，依度既係noun。你一定會感奇怪，點解story係noun，book又係noun呢!原因係依度story既noun用黎形容book既noun。

又例如好似student card,apple pie,english camp 都係咁既形式架!!!

另外story都可以以verb既形式出現，解為描述，但一定要係vt.先得bo!!

Sentence = Subject + verb + object

(I) and (she) are subjects;
(am reading) and (is watching) are verbs;
(a story book) and (TV) are objects
(and) is a conjunction connecting two simple sentences.
