Complex Sentences & Adverbial Clauses

What do you already know about complex sentences and adverbial clauses?

Learning Objective

At the end of the lesson you will be able to identify, understand, and use complex sentences with adverbial clauses to express reason, time, place, and conditions.

What Are Complex Sentences?

A complex sentence has a main clause and at least one subordinate clause. It helps express more detailed and precise ideas.

The Structure of Complex Sentences

Main clause: expresses the main idea. Subordinate clause: adds information, often introduced by conjunctions like 'because', 'when', 'although'.

What Is an Adverbial Clause?

An adverbial clause is a subordinate clause that gives more information about the verb: time, place, reason, manner, or condition.

Types of Adverbial Clauses

Time ('when'), place ('where'), reason ('because'), manner ('as'), condition ('if', 'unless'), contrast ('although').

Example: Paul the Octopus

Paul could predict football results every time he was asked. ('every time he was asked' – time)

Understanding Time Clauses

Adverbial clauses of time answer 'when?'. They use conjunctions like 'when', 'while', 'after', 'before', 'every time'. Example: 'He answers when he knows the answer.'

Understanding Place Clauses

Adverbial clauses of place answer 'where?'. They use 'where', 'wherever'. Example: 'Hundreds came to see Hans wherever he appeared.'

Reason Clauses

Adverbial clauses of reason answer 'why?'. They use 'because', 'as', 'since'. Example: 'The horse became famous because he could answer any question.'

Condition Clauses

Answer 'under what condition?'. Use 'if', 'unless', 'provided that'. Example: 'Hans could not answer if he couldn't see the questioner.'

Case Study: Clever Hans

Clever Hans appeared intelligent until scientists controlled the conditions. ('if either of two circumstances existed')

Case Study: Clever Hans

Clever Hans appeared intelligent until scientists controlled the conditions. ('if either of two circumstances existed')

Why Use Complex Sentences?

They show advanced thinking and connect ideas clearly, making your arguments and explanations stronger.

Recognising Adverbial Clauses

Look for conjunctions like 'if', 'because', 'since', 'when', 'wherever'. The clause they introduce is usually an adverbial clause.

Sentence Matching: Analyse Meaning

Match adverbial clauses to the main clause. Q: What extra information do the clauses in bold give?

Example Breakdown

Paul the octopus could predict Germany's World Cup results every time he was asked.

Sentence

What is added?

It tells us how often he could predict (time).

Exercise: Complete with Clauses

Some people thought Paul was intelligent because ... (add your own reason). Practice making your own complex sentences.

Comparing Answers

Work with a partner or group to compare your sentences and discuss which adverbial clauses you used.

Listening: Intelligence & Feelings

Summary: Clever Hans & Paul the Octopus

Both stories use complex sentences and adverbial clauses to explain animal intelligence and scientific investigation.

Reflection: Using Complex Sentences

Think about how complex sentences help you explain ideas more clearly, especially in exams and discussions.

Next Steps

Try writing five complex sentences about animals or intelligence using adverbial clauses. Share your sentences with a partner.
