Composition Exercise
Fill in the gaps with the words or expressions in bold used in the model essay above.

The diagram compares the process by which electricity is generated in two types of hydroelectric power station.  Overall, electricity produced by a plant is traditionally produced in three stages, as opposed to in five stages at a run-of-river hydroelectric plant.

In a traditional hydroelectric power plant, river water rises behind a dam until it is sufficiently high enough to enter an intake pipe near the top.  Once it enters, the water flows down into a much lower turbine chamber whereupon it causes the machine’s blades to rotate, thus generating electricity.  This power is then sent via transmission lines to customer’s homes.

On the other hand, in a run-of-river hydroelectric plant, the natural flow of the water running downhill is harnessed to turn the turbine blades.  Initially, water is channeled away from the water’s primary path down a pipe into a turbine building further down the hill.    On entering the building, the water causes turbine blades to rotate which in turn spins a generator that produces electricity.  This power is then conducted by transmission lines above the plant to where it’s needed.  Surplus water then exits the plant and rejoins the river to resume its original course.

Step 1: Analyzing question

Make a Plan: (3-4 mins)

Overall

Compare/two types of hydropower generation

Difference: 3 stages vs. 5 stages

Traditional hydroelectric plant

Water rises enters intake pipe flows into a turbine chamber generates power

Run-of-river plant

Water channeled into a pipe   flows into turbine room rotates turbine blades spins generator produces electricity.

QUESTION:

The diagram shows the process by which electricity is generated in two types of hydroelectric power station.

Summarise the information by selecting and reporting the main features.

Write at least 150 words.

Step 2: Planning
Introduction + Overview (5 mins)
  • Paraphrase the question & state key details.
Overview: (3 mins) Body Paragraph 1 (5 mins):
  • Describe first half of process
Body Paragraph 2 (5 mins):
  • Describe second half of process
Check work (1-2 mins)

If you have many grammar/spelling mistakes, you could check your work sentence by sentence to help you quickly reduce them. Otherwise, you should spend a few minutes at the end of the writing period to check for the following.
