Hi, fellas. Last week we learned how to structure our writing about a process in IELTS Task 1 (More: https://englishtips4u.com/2018/07/07/engtips-process-ielts-writing-task-1/). Today we will focus on when to use active voice or passive voice in such kind of writing.
1) Active Voice
Active voice is used to describe natural processes or events occurring autonomously in nature, where humans are not involved, such as rain and formation of clouds.
Beginning at the evaporation stage, 80% of water vapour in the air comes from the oceans. Heat from the sun causes water to evaporate, and water vapour condenses to form clouds. At the second stage, precipitation, water falls as rain or snow.
2) Passive Voice
Passive voice is used to report processes of manufacturing a product in a factory or workshop. In passive voice, the action is more important than the person performing it.
At the fourth stage in the process, the clay bricks are placed in a drying oven for one to two days. Next, the bricks are heated in a kiln at a moderate temperature (200 – 900 degrees Celsius) and then at a high temperature (up to 1300 degrees), before spending two to three days in a cooling chamber. Finally, the finished bricks are packaged and delivered.
