By a normal sentence I mean any sentence of the form subject + predicate. Every sentence that is not normal is called advanced. A simplest example of an advanced sentence is, say, Being a doctor, he often voluntarily helps people around him.
Since I am not a native speaker in english, from time to time I found it difficult for me to discern the meaning of a given advanced sentence. But for a normal sentence I found it readily intelligible.
Which readings could help improve this asymmetry of understanding english? Further, which books may give rules or advices relevant to understanding advanced sentences for non-native english speakers?
Thanks so much.
