  1. The diagram illustrates production system of hydro-electric power. Overall, from the evaporation of the water in the biosphere to the consumption of generated hydro-electricity in daily usage followed by various stages are represented here in detail.
    It can be seen that water from the sea after being evaporated by the sun’s heat joins the cloud formation which results in rainfall. This storm water after being collected in the reservoir passes through the dam while the valve continues being opened or closed to control the water flow. This water is directed straight to the turbine and generates the electric power which is being propagated in the high voltage cables from one tower to another. However, the water after creating power in the turbines is recycled back to the reservoir via a pump.
    Afterwards, the produced hydro-electric power goes to the transformer station from the tower and then is being transferred to the hospitals and schools via the underground cables in order to be used in daily works

    The diagram shows the process of generating electricity using water. There are six stages involved in this process, which begins with water evaporation and ends with the supply of electricity for usage.
    Initially, sea water is exposed to the sun, causing it to evaporate and form clouds. These clouds then lead to downpour of rain in a reservoir with a large dam built to stop the water flow. Next, the water flows to a turbine through a system of valves which can be controlled to open or close. The turbine then generate electricity based on the power of the water. At the same time the water is pumped back to the reservoir from the turbine for later use.
    Following this, electricity flows to a transformer station through a system of high voltage cables, which are constructed far away from living areas. At this station, the electricity is adjusted to be safe for daily usage before it is finally provided for consumption in hospitals or schools through underground cables.
    Overall, this process is an efficient way of generating electricity using water.

    • I don’t usually comment in writing. But in this case, I want to say that you haven’t read my lessons or my model answers. There is only one overview and it’s the most important statement in your task 1 report. You have split your overview. You have an overview statement mixed with your introduction (There are size stages … etc) and another at the end of the report where you state your opinion. 1) You must have one overview and you should make it clear that it’s an overview using “Overall”. 2) You never state your opinion. 3) There’s no conclusion – this isn’t an essay. Please go to the writing task 1 section of this website and learn more.

    The diagram illustrates the process involved in generating hydro-electric power.
    Overall, the generation of this type of energy is the result of a set of steps starting from evaporation, followed by collection of the water, production, and transformation for human use.
    At the initial phase, the rays of the sun turn sea water into vapor which is then condensed to form clouds. When clouds accumulate enough vapor, it precipitates. This rain is collected in a separate reservoir protected by a dam which has a valve that opens and closes. This valve helps to control and allow water flow into the turbine.
    In the next stage, the turbine that is attached to high voltage cables transforms water into energy. The excess water is pushes back to the reservoir by a pump for later use. The energy created by rotating the turbine travels into a transformer station. This station is connected to underground cables distributing energy to houses, factories, hospitals, and schools.

  4. Muhammad Ishaq says

    The picture illustrates the process of producing electricity using the hydro-electric power generation and how to supply it via cables. There are nine stages in producing electricity and then supplying electricity to people.
    Initially, Sun shines, and it makes the water evaporate. The evaporated water forms a cloud. After that, Rain happens, and water is stored in the reservoir of the Dam. Next, the valve opens so that turbine is rotated with the flow of water and closes after some time. Then, the water goes to the pump and is pushed by the pump back to the reservoir. In this way, the electricity is generated by rotating a turbine.
    The next procedure is that the electricity is brought to the transformer station with the help of High Voltage Cables. Then, the electricity is divided at the transformer station for houses, industries, schools and hospitals. The final step is that the underground cables network is used to supply electricity to the people for homes, industries, schools and hospitals.

  5. Nafija Khanom says

    The diagram illustrates the process of hydro electric power generation. This process involves various steps to reach the final stage.
    Overall, it can be seen that hydro-electric power generation is a multi-steps linear process which involves evaporation, collection, production and transformation.
    At the beginning stage, sea water is heated by the sun which causes evaporation that in later resulting rain. The rain water is then collected in a reservoir which is controlled by a dam. From the dam, the water flow is controlled by a volve which opens and closes to allow the flow of water to the turbine.
    In next stage, turbine generates the power and the excess water is backed to the reservoir through the pump for future use.
    From the turbine, the electricity is transferred through the high voltage cables to the transformer station. Subsequently electricity is passed through the underground cables and being used in the hospitals, schools, houses, factories and so on.

  6. Sneha sabu says

    The diagram illustrate how electricity is produced from water.
    Overall, it involves production and distribution of electricity from water.
    At initial stage, water from sea evaporates due to heat from sun. The resultant vapors, form mist in cloud thereby producing rain. The rain water is collected in reservoir or dam. When the valve of reservoir is opened, water at high pressure rotates the turbine producing electricity.
    Distribution of electricity is done by high voltage cables. The current produced at the dam is supplied to the transformer. Which is then distributed to various places like school, colleges, houses,industries etc.

  7. Ajaz Khan says

    The given illustration describes the process of generating electricity through a natural resource that is water.
    Initially, the water is gathered from the sea, with the basic phenomenon of evaporation, the clouds convert the vapor into water droplets, which results in rainfall getting collected in a reservoir which is enclosed by a dam. The flow of water is controlled by a valve, which can be operated manually upon use.
    For generation, the valve is opened, the water flows towards the turbine, which in turn creates electricity. This generated electricity is passed through the High Voltage cables towards the Transformer Station. Upon its arrival, the electric current is provided to different sectors such as houses, factories, hospitals and schools with the help of underground wiring.
    The water which travelled towards the turbine to create electricity, passes through the pump which sends it back to the reservoir for storing and further usage. Hence, this cycle continues.

    The diagram illustrates the process and production of hydroelectric power. This process involves various methods to reach the final stage.

    Overall, the rainwater is primary most important in the production of hydroelectric power. It is a continual process that involves evaporation, rainwater, reservoir, turbine, and distribution of electricity to the houses.

    Initially, the seawater is observed by the clouds in the presence of sunlight, this process is known as evaporation, once the clouds observed enough water from the sea. Due to condensation process the clouds precipitates and form into rainwater, and these rainwater stored in a reservoir for various purposes and the reservoir is being controlled by the valve which is used to open and close the doors of the dam/reservoir and then the water is being sent to Turbines.

    Once the water reaches the turbines the electricity is being generated. The generated electricity is transmitted through the high voltage cables to the transformer station. From there the electricity is being sent to houses, factories, schools, and hospitals through underground cables.

    Thank you very much mam for the work you are doing for all of us. I have learned so many things from here and improved me a lot.
    Here I am posting my writing and am expecting that you will rectify my mistakes.

    The diagram illustrates how hydro-electric power is being generated through various processes. Overall, the sea water forms cloud through evaporation and it is collected in a reservoir after raining.The flow of water is being converted through various processes to produce electricity.

    Initially, the rain water is collected in a reservoir which is controlled by the dam and a valve is there to open and close the dam depending on the water flow. From this point the water is directed towards turbine to make hydro electric power. The excess water is backed to reservoir being pumped.

    After the generation of electricity, it is directed straight through high voltage cables to the transformer station. From there the electricity travels into the underground cables and reaches to the hospitals and schools in the town.

  11. Hi Liz,
    great page! Thank you very much for doing this.
    I´m quite sure there´s a “for” missing in the text just before (10). The sentence made no sence to me until I read the answer where the “for” suddenly appeared.

    Kind regards
    Oscar

  12. Rustam Assanbayev says

    The answer:
    The diagram illustrates the process of generating hydro-electric power.
    Overall, the process consists of circulation of liquid and gas transferring through high voltage cables to various points.
    To begin with, water evaporates from the sea due to the sun`s heat, and after, as rain falls water is collected in the reservoir. The movement of the water is regulated by the valve of the Dam where the collected water goes to the turbine for producing electricity.
    The next step is the produced electricity is directed through the high voltage cables to the transformation station. Finally, it is transferred via the underground cables to houses, schools, factories, and hospitals.

  16. Hi Liz,when giving information about a diagram -take for instance the one on generation of hydro-electric power where the distribution of the electricity by underground cable is to two structures not labelled and then to schools and hospitals.Though this structures are not named but we know what they look like,can the assumed names be written without having it on the diagram.
    Thanks

    • If the structures are easily identifiable, you can write them. However, although I can see one is obviously housing, the other is not so clear. So, you could refer to housing and other buildings. You can only assume when the image is evidently symbolic of something.
      All the best
      Liz

  17. Dear Liz,
    I was watching an important example of T1 about “the water usage in the average Australian home during the years 2004” which was the combination of the diagram and the graph. Unfortunately , I missed it suddenly and could not find it again. It was explaining the steps of writing clearly.
    Please help me to have this lesson via direct link. This is the weakness of me in T1 how to mix two sources of data.
    Regards
    Rozita

    • Please look through my writing task 1 lessons and also the practice charts.

  19. Sherif Mahmoud says

    Hi Liz, thank you very much for you great help to all of us , I am looking forward to meet you soon to thank you again.
    would you please have a look on this?
    Yours , Sherif .
    the underlying diagram shows how electricity is generated from water.
    Overall this process is divided into two parts, generation and distribution. The generation starts when sun heat evaporizes sea water , leading to formation of huge clouds rich in rain water ,which falls later in a reservoir sealed by a dam and close and open valve.
    The water is allowed to flow through the valve to pass into a turbine and a pump, to produce electricity and to bring the water back into the reservoir ,respectively.
    the electrical current which is generated from the first step will be transferred via high voltage cables to transformation stations to modify its strength before sending it to homes, schools, hospitals and other facilities.

  20. Ismail says

    Hi Liz sorry for disturbung I also would like read your comment about my writing
    This diagram shows how to produce electricity from the water.
    First of all sun rises and makes saline water from sea evaporate.In the sky vapour condenses and converts to the clouds.If clouds full rain occurs.Then rain water collects into the artificial reservoir,which has dam to protect water from overflowing.The valve which is installed behind the dam is used to control the amount of water.Next water flows through the valve to the turbine.Simultaneously pump which is installed beneath turbine pumps water again to the reservoir and causes the water to circulate.This process causes to produce electricity.After that electricity flows through high voltage cables to the power towers.Finally after passing power towers electricity is transferred for consuming.
