Simple, Compound and Complex Sentences Worksheet

Writing skills lesson 27: Complex sentences · Set 636 · 40 questions

Writing tip (One clause leans on the other): Find the clause that starts with because, although, if, when, since, who, which or that — the subordinate clause (When the rain stopped). On its own it is not a complete sentence. The rest is the main clause (we went out to play): it makes complete sense alone. Choose the joining word by meaning: because → a reason, although → a surprise, if → a condition, when → a time, since → from a time until now, who → a person, which → a thing, that → what someone says, thinks or knows. Sort any sentence: one clause → simple; two main clauses → compound; a main clause + a subordinate clause → complex.
