Complex Sentence Structures

Read each example carefully. Identify clauses and sentence structures, then consider how structure can shape a reader’s response.

Recognising sentence structures

Sentence structures can organise ideas and influence emphasis, contrast and reasoning.

1.Read this sentence: “Although the campaign promised safer streets, residents questioned its cost, and the council delayed its decision.” Which sentence type is it?

Simple
Compound
Complex
Compound-complex

2.In “Although the campaign promised safer streets, residents questioned its cost, and the council delayed its decision,” write one complete main clause.

3.In the sentence “While the proposal sounds appealing, it may shift costs onto renters because landlords could raise their fees,” which words introduce subordinate clauses? Select all that apply.

While
appealing
because
their

4.Match each sentence structure with the effect it can create in persuasive writing.

Simple sentence
Compound sentence
Complex sentence

Can show how one idea depends on, explains or contrasts with another
Can give a claim strong, direct emphasis
Can place related or contrasting main ideas side by side

Building and analysing complex sentences

A subordinate clause adds information but cannot usually stand alone as a complete sentence.

5.Complete this persuasive sentence by adding a subordinate clause beginning with “because”: “The community should protect the wetland …”

6.Write a subordinate clause beginning with “When” to complete this sentence: “When …, the school community can make better-informed choices.”

7.Combine these ideas into one complex sentence: “The council opened the park after dark. Nearby residents asked for better lighting. They wanted visitors to feel safe.”

8.Analyse the structure of this short appeal: “Act now. If we reduce food waste, we can save money and protect valuable resources. Every meal matters.” Explain how the sentence variety supports the appeal.

Using structure persuasively

Apply sentence variety to a fresh issue. Use precise reasoning and language suited to your intended audience.

9.Write a complex sentence arguing that people should check information before sharing it. Include one of these subordinating conjunctions: although, because, when, while or since.

10.Write a persuasive paragraph of three or four sentences encouraging teenagers to get enough sleep. Include at least one complex sentence, a rhetorical question, emotive language and a mix of sentence lengths.

11.Explain one way a complex sentence can strengthen a persuasive argument compared with a series of simple sentences.
