Complex sentence worksheets are worksheets that have complex sentence problems. Students usually need to identify the complex sentences from other types of sentences, join sentences together into a complex sentence using subordinating conjunctions or write their own complex sentences. They are helpful for teaching grammar to children or ESL students.
Complex sentences are one of three types of sentences in English grammar, with the other two types being simple sentences and compound sentences. They join a dependent clause and an independent clause together into one sentence by using a subordinating conjunction to connect them. Subordinating conjunctions show opposition, cause and effect, express time or express conditions.
