Teachers at all grade levels are often faced with students whose word analysis and vocabulary skills are adequate, yet who have a problem reading and understanding connected text in sentence form. Problems in sentence comprehension become particularly marked when students are asked to deal with the complicated sentence structures typical of more advanced reading material. Such sentences may have multiple subjects and predicates, embedded clauses and phrases, passive voice, and/or unusual word orders.
