How to use this lesson: choose a band in the Band Standard bar (left; on a phone, at the top). Every step then shows sentences, exercises and the model for that band. Start at your current band, then try the next one up.

1How many stages? Name them.

The diagram has 8 stages. It is a man-made process shown as a linear sequence – from milking cows on a farm to delivering cartons and bottles of milk to shops.

Phase 1 – On the farm and transport (Stages 1–3)

  1. 1
    MilkingCows are milked by machine.
  2. 2
    Cooling and storingThe milk is stored in a cold tank.
  3. 3
    TransportA tanker takes the milk to the factory.

Phase 2 – At the factory and delivery (Stages 4–8)

  1. 4
    TestingThe milk is tested for quality.
  2. 5
    Pasteurising*The milk is heated to 72°C for 15 seconds.
  3. 6
    CoolingThe milk is cooled quickly.
  4. 7
    PackingThe milk is put into cartons or bottles.
  5. 8
    Delivery to shopsRefrigerated lorries take the milk to shops.

Paraphrase the task sentence. The column of your band is highlighted.

Tip: “from the farm to the shop” is fine to keep at lower bands. At 6.5+ use “the point of sale” or “retail outlets” to avoid copying.
Sample Introduction – Band 4.5

The diagram shows how milk is processed, from the farm to the shop.

Band 4.5: changes “the stages in processing milk” into “how milk is processed” – simple and correct.

Sample Introduction – Band 5.5

The diagram illustrates the process of preparing milk from the farm to the shop.

Band 5.5: a common reporting verb (illustrates) and a noun phrase (the process of preparing milk).

Sample Introduction – Band 6.5

The diagram illustrates the various stages involved in processing milk, from the dairy farm to the point of sale.

Band 6.5: a noun phrase with “involved in” and an accurate paraphrase of “shop” (the point of sale).

Sample Introduction – Band 7.5

The given diagram depicts the sequence of steps through which milk passes from the dairy farm to retail outlets.

Band 7.5: precise verb (depicts), a “through which” relative clause and an academic collocation (retail outlets).

Template for students

The diagram shows / illustrates / depicts how milk is processed / the processing of milk, from the dairy farm to the shop / retail outlets.

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 “4°C”, “72°C” or “15 seconds”).

Band 4.5 formula

Overall, there are number steps in this process. It starts with V-ing / N and finishes with V-ing / N.
Example – Band 4.5

Overall, there are eight steps in this process. It starts with milking cows on a farm and finishes with taking milk to shops.

Why Band 4.5: Two short simple sentences, basic words (steps, starts, finishes), no phases.

Band 5.5 formula

Overall, there are number stages in the process. The first number stages happen place / phase A, and the last number happen place / phase B. The process begins with V-ing and ends with the + N of + N.
Example – Band 5.5

Overall, there are eight stages in the process. The first three stages happen on the farm and on the road, and the last five stages happen at the factory and end with the delivery of milk to shops. The milk is kept cold for most of the 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 number stages in the process, which can be divided into two main phases: A and B. The process begins with the + N of + N and ends with the + N of + N.
Example – Band 6.5

Overall, the process consists of eight stages, which can be divided into two main phases: collecting the milk on the farm and treating and packaging it at a factory. It is also clear that the milk is kept cold at almost every stage.

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 process comprises number + distinct stages, which fall into two main phases – A and B – commencing with the + N of + N and culminating in the + N of + N.
Example – Band 7.5

Overall, milk processing involves eight distinct stages, which fall into two main phases – collection on the farm and treatment at a processing plant – with the milk being kept at a low temperature throughout, apart from the brief heating stage.

Why Band 7.5: comprises · distinct · fall into · dashes for the phases · commencing with … culminating in … in ONE sentence.
