sentence diagrams

[slow2speak@gmail.com]

I have several sentences below that need checking.

1. Miles and Edward struggled and finally escaped from the scornful crowd
S CON S V CON ADV V PREP ART ADJ OP

Yes, I realied that I only sent one sentence after all.

The OP means Object of the Preposition.

I also sent two other sentences, questioning the identification of predicate adjectives. They are as follows:

1. Mrs. Canty seemed perplexed about her son's true identity.
S , LV, Prefd Adj? Prep, pos.pronoun ,pos.adj, adj, OP


2. Miles and Edward became discouraged during the night's adventures.
Com.Sub LV Pred Adj?? Prep AA Pos. Adj OP

If they are identified properly, then do I use the slanted line pointing back to the subject to diagram the predicate adjectives?

Thanks so much!
