IELTS Academic Writing Task 1 with answer.
You should spend about 20 minutes on this task.
The diagrams show a structure that is used to generate electricity from wave power.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
You should write at least 150 words.
Sample Answer:
The given diagrams show how the electricity is generated from the sea wave power. As is observed from the given pictorials, both high tides and low tides are used for generating the electricity.
According to the given diagrams, the whole structure is placed near the cliff of sea wall. The structure for generating electricity from sea waves has turbine placed inside two columns. One part of the column is fixed with the cliff of sea wall while the other part is extended towards the sea. The chamber is a curved shaped extension of the column that helps to create the air pressure.
During the high tide, the wave flows towards the column and thus creates huge air pressure and this air pressure rotates the turbine with great speed. The rotation of the turbine is used to generate the necessary power for the creation of electricity. During the low tide, the air direction gets reversed and this pressure again rotates the turbine in a great speed. The high tide and low tide are both used to generate air pressure and the air pressure is then used to rotate the turbine in an accelerated speed to generate the electricity.
