			1. Text organisation.
			
			  
				
TIP:
				Giving your writing text a clear structure will help you to write it quickly and will also make it easier to read and understand. There are many ways to organise a text, depending on the topic and content. Common patterns are:
topic – comment
				
				problem – solution
				
				question – answer
				
			  cause – effect
			   
			Match the patterns to the examples.
			
		 
		
		
			2. Text organisation.
			In a longer text it is very common to find a combination of the approaches introduced in the previous exercise. Often each paragraph fulfils a different, specific function.
			Read the question and the sample answer. Which function does each paragraph of the sample answer fulfil?

					To + infinitive is used to describe a purpose; it answers the question "Why ...?" It is also commonly used when the subject of the clause is a person, or with a passive where the agent is a person.
