Unit 1: Clause and sentence structure. Main points: Simple sentences have one clause. Clauses usually consist of a noun group as the subject, and a verb group. Clauses can also have another noun group as the object or complement. Clauses can have an adverbial, also called an adjunct. Changing the order of the words in a clause can change its meaning. Compound sentences consist of two or more main clauses. Complex sentences always include a subordinate clause, as well as one or more main clauses
