Student can describe continuous natural cycles using appropriate active verbs and cyclical language.
Explanation of natural cycles versus linear processes.
In IELTS Writing Task 1, a linear process (like making bricks) has a clear start and finish. A natural cycle (like the water cycle or a butterfly's life) is different.
It is a continuous loop. It never truly ends. Because of this, the vocabulary and grammar you use must show that the final step loops directly back into the first step.
