The Task
The diagram below shows the life cycle of the silkworm.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.
1How many stages? Name them.
The diagram has 5 stages. It is a natural process (a life cycle) shown as a cycle: eggs hatch into silkworms, which spin cocoons, change into moths and lay new eggs.
Phase 1 – Egg and feeding silkworm (Stages 1–2)
- 1EggsTiny eggs are laid on mulberry leaves.
- 2Silkworm feedingThe silkworm eats mulberry leaves and grows quickly.
Phase 2 – Cocoon and adult moth (Stages 3–5)
- 3Spinning a cocoonThe silkworm spins a cocoon of silk thread around itself.
- 4PupaInside the cocoon, the silkworm changes into a pupa.
- 5Adult mothAn adult moth comes out of the cocoon and lays eggs.

8Overview
An overview gives the number of stages and the start and end; higher bands add the two main phases in more precise language. No details (no “10 days”, “4–6 weeks”, “3–4 days”, “2 weeks” or “mulberry leaves”).
Band 4.5 formula
Overall, there are five steps in this life cycle. It starts with eggs on mulberry leaves and finishes with a moth laying new eggs, so it is a cycle.
Why Band 4.5: Two short simple sentences, basic words (steps, starts, finishes), no phases.
Band 5.5 formula
Overall, there are five stages in the life cycle. The first two stages show the egg and the young silkworm, and the last three show the cocoon and the adult moth. The cycle begins with eggs being laid on mulberry leaves and ends with an adult moth laying eggs, so it is a cyclical process.
Why Band 5.5: Names the two parts in simple words; begins with … ends with …; no numbers or details.
Band 6.5 formula
Overall, there are five stages in the life cycle, which can be divided into two main phases: the egg and feeding stage, and the cocoon and adult stage. The cycle begins with the laying of eggs on mulberry leaves and ends with adult moths producing eggs of their own, so it is a cyclical process.
Why Band 6.5: A which-clause divides the stages into two phases; nominal phrases (the harvesting of, the production of).
Band 7.5 formula
Overall, the life cycle comprises five distinct stages, which fall into two main phases – hatching and feeding, and cocoon formation and adulthood – commencing with the laying of eggs on mulberry leaves and culminating in the emergence of an adult moth, from where the cycle repeats.
Why Band 7.5: comprises · distinct · fall into · dashes for the phases · commencing with … culminating in … in ONE sentence.
