BAND 9.0 Reports: Processes – Hydropower

T1 Processes - Hydropower

THINGS TO REMEMBER FOR PROCESSES –

(1) Often the process will contain some words that are unfamiliar. Don’t worry. They are often unfamiliar to native speakers too. For example, in the above process, almost no native speakers will know what a “Penstock” is. To solve this problem, simply use an appropriate verb and write the unknown term with correct grammar. In this example, it seems like “water flows into/enters the penstock”, so that’s ALL you need to write.

(2) Processes are a series of steps, so make sure you use a variety of linking vocabulary (No repetition if you can). See the sample below for examples.

(3) Processes normally require you to use the present passive tense. This is because something is being done to something. For example, “bread is made by the baker” NOT “The baker bakes the bread” because the process is about baking bread not bakers. The exception is natural processes where the present simple tense is used. Do NOT use “will” or other future tenses.

(4) A good description/report is one where the reader can picture/imagine what the diagram looks like (and even re-draw it) without having seen it.

STEP-BY-STEP GUIDE

NOTE – Advanced vocabulary and synonyms are included in bold. Linking vocabulary is included in italics.

Step 1 – Introduction

TITLE – The diagram shows how electricity is produced by a hydroelectric dam.

SAMPLE (paraphrase the title) – “The diagram illustrates the production of power through the use of a hydroelectric dam.

TIP – you don’t need to think of a synonym for “hydroelectric dam”, but always try to have synonyms for “shows” and common words like “produce” (e.g. “generate”) and “electricity” (e.g. “power”)
Step 2 – Overview

SAMPLE – The process begins with water in a reservoir and ends with the transmission of power via long-distance power lines.

TIP – In the overview for your process, you can report how many stages there are or – if it’s unclear (like this one!) – you can mention the start and end points of the process.
Step 3 – Body

“In order to generate hydroelectricity, the first step is to collect water in a reservoir. When power generations begins the water passes through an intake in the bottom of the dam and then enters a long tunnel called a penstock. On the other hand, when power is not being produced, the intake is blocked by a large gate that prevents the flow of water. However, when the intake is opened, the water flows down the penstock and the pressure it creates is used to spin a turbine, which is connected to a generator in a place referred to as the powerhouse. At the same time, the water that has gone through the turbine flows out into the river below the dam. Finally, the generator in the powerhouse is connected to power lines which are used to transport the electricity over long distances.
