WRITING TASK 1 You should spend about 20 minutes on this task. The diagram below shows how one type of coal is used to produce electricity. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. You should write at least 150 words.

The diagram depicts the production process of electricity

that is

made from coal.

Overall

, there are nine stages of the process, beginning with mining the basic resources in order to collect a coal group and ending with electricity distribution,

Firstly

, workers need to mine natural resources and it will become a coal group in the second step.

Then

, they are damaged by a crusher to become smaller forms before collecting them in a large transporter. Moving to the next step, a truck will distribute the coal dust to the gasifier where solid waste and gas are produced.

While

the solid waste will be disposed of, the produced gas is cooled down to a cooler in the next stage. The processed gas is manufactured in a power plant to produce electric energy, and in

this

stage, it is expected to have a heat waste which will be discarded.

Finally

, when the electricity has been made, it is ready to be distributed and utilized by industrial and housing areas.
