IELTS Process Exercise 
The most important parts of successfully writing about process is understanding the passive voice.  
The Passive Voice 
1) The passive is used for processes because the focus is on the action, not the person doing it. So 
the object is made the subject.  
 Active = John takes the dog (object) for a walk every morning. 
 Passive = The dog (subject) is taken for a walk every morning. 
2) An active sentence is also made passive by adding the verb 'to be' and changing the current verb 
into the past participle 
 Active = John takes...  
 Passive = The dog is (to be) taken (past participle)... 
3) Intransitive verbs (verbs that do not take an object) cannot be made passive:  
 The baby sleeps.  
 The dog barks loudly. 
 The staff arrive at 8.30 am.  
 
Practice 
Now it's your turn to practice. 
Some important points before you start: 
 Turn the verb you are given into the passive - if appropriate! (remember intransitive verbs 
cannot be passive!). 
 Don't forget subject verb agreement. 
 Type in small letters and do not leave a space after the last word (this will make the computer 
mark it as wrong). 
 If the word '+ then' is included, place 'then' between the verb 'to be' and the past participle: 
 The water (to heat + then) .......... to 100 degrees.  
 The water is then heated to 100 degrees.

The diagrams below show the stages and equipment used in the cement-making process, and how 
cement is used to produce concrete for building purposes.

for making the cement and one for the concrete. The cement must (1. to make) 
____________________ first, as it (2. to use) ____________________ to make the concrete. 
To make cement, firstly limestone and clay (3. to feed) ____________________ into two rollers 
which (4. to crush) ____________________ them up into a powder. This power (5. to mix + then) 
____________________ together, before (6. to travel) ____________________ down a tube and 
into a rotating heater. 
The heat comes up from the bottom as the heater rotates, and once the power is ready, it (7. to 
emerge) ____________________ from this machine onto a conveyor belt where it (8. to grind + 
then) ____________________ into the cement. Finally it (9. to separate) ____________________ 
into bags. 
This cement is then used to produce the concrete. To do this, there is a mixture of 15 per cent

Answers Discission 
Let's just go through some of the answers to the IELTS process exercise in case you did not 
understand them. 
1. (to make) be made - 'must' is a modal verb, so the verb 'to be' is in the infinitive. 
2. (to use) is used 
3. (to feed) are fed - there are 2 subjects so the plural verb is used. 
4. (to crush) crush - the limestone and clay are still the objects ('them'), not the subjects, so it 
should not be made passive  
5. (to mix + then) is then mixed. 
6. (to travel) travelling - travel is intransitive, also as it follows 'before', it takes the -ing form.   
7. (to emerge) emerges - emerge is intransitive. 
8. (to grind + then) is then ground 
9. (to separate) is separated 
10. (to place) are placed - plural verb to agree with 'these'.
