Point of view
Point of view means your own meaning about one text or a case. It can be your opinion about politics or your meaning about one text from the newspaper.
It can also be in what way you put a text in. Who will you support and who are you against. It's all up to yourself.
In the text "the way up to heaven" we have to make our own opinion about if we support mrs. Foster's when she left her husband. Often we support the main character in the text, which in this case was mrs. Foster.

Concord

Different between adverbs and adjectives

The adverbs describes verbs (play,jump,walk)
ex: he jumps very high.

The adjectives also describes something, but it doesn't describes the verbs. The adjectives describes the nouns.
ex: my dad is very thin

Mrs. Foster
She is the main character in the text, "the way up to heaven". She's an old woman which is married to Mr. Foster. Mrs. Foster is a very nervous woman and her biggest fear is to miss a train or a plane. As I said is mrs. Foster married to Mr. Foster. He is a very mean man and he doesn't love her at all so she is very unhappy. Her biggest dream (I think) is to live rest of her life with her grandchildrens in Paris.
