How to avoid waste of energy?
With fast growth of civilization there is also an ever mounting need for energy. Energy may be in the form of fuels or electricity. Petrol is a liquid fuel which is used widely nowadays. But this kind of fuels is likely to be exhausted at the rate man is using it recently.
To meet the challenge, various methods have been suggested. One is to minimize the man’s demand in using the energy. Non-essential consumption should be minimized. During certain days of the year, people all over the world turn off the electricity for 1 hour to save the energy. Modern gadgets consuming energy should only be used when they are absolutely necessary.
Energy conservation is possible through modernization of plant and equipment. People should replace the obsolete equipment by the modern ones.
Energy can be saved on transport by the following methods. People should commute by the rail rather than by cars and vans. The transport must be improved with a view to sparing the energy. Cities must be planned in such a way that the commuting distance from this place to others is minimized.
In industry, many things could be done to reduce waste of energy or to economize energy. The machine maintenance needs to be tightened; heater must be utilized properly. When systems are streamlined, economy in fuel is obvious. Instead of using materials requiring higher energy, those which require lower energy should be used.
We hope man with his ever rising urge for existence will cope up with this urgent problem and find alternatives.

Hi everyone! My name is An and today I’m going to give you some useful information about how to save water at home.
Well, we all know that water is an integral part of our life; thus, we cannot stop using it but just reduce the amount of water we use daily. These following tips will help us to cut down on water waste.
Firstly, we should regularly check faucets, pipes and toilets for cracks to ensure that any leaking toilet tanks or dropping taps are fixed as soon as possible. Secondly, don’t forget to turn off the taps while we are brushing our teeth, washing our face or getting a shave as we can save up to 5 liters of water per minute. Thirdly, having a shower uses much less water than bathing in a bathtub, so try to take a shower every time you can. Another tip is to run washing machines and dishwashers only when we have enough dirty clothes and dishes for full loads. Lastly, never think of using the toilet as an ashtray or a wastebasket for cigarette butts, facial tissues, tea bags and other kinds of small trash because flushing these items can waste about ten liters of water each time.
It can be concluded that these five simple actions help us save water, save our own money and prevent water pollution as well.

ADVANTAGES OF HYDROPOWER: (Tác dụng của năng lượng Hydro) (Tham khảo)

  • Hydropower is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas.
  • Hydroelectric power is a domestic source of energy, allowing each state to produce their own energy without being reliant on international fuel sources.
  • The energy generated through hydropower relies on the water cycle, which is driven by the sun, making it a renewable power source, making it a more reliable and affordable source than fossil fuels that are rapidly being depleted.
  • Impoundment hydropower creates reservoirs that offer a variety of recreational opportunities, notably fishing, swimming, and boating. Most water power installations are required to provide some public access to the reservoir to allow the public to take advantage of these opportunities.
  • Some hydropower facilities can quickly go from zero power to maximum output. Because hydropower plants can generate power to the grid immediately, they provide essential back-up power during major electricity outages or disruptions.
  • In addition to a sustainable fuel source, hydropower efforts produce a number of benefits, such as flood control, irrigation, and water supply.

      I love listening to music, so I know a lot of famous bands, but my favorite band is BlackPink. Black Pink is a girl group founded in 2016 with a relatively young age, but Blackpink has achieved many remarkable achievements. When Blackpink debuted in 2016, the two songs "Boombayah" and "Whistle" quickly gained attention thanks to their strong and vibrant melody. Blackpink's influence does not just stop at the music field, especially in Korea, the group also expands into the fashion field. The group's image emphasizes fashion and personality both on and off stage. Although the costumes can show typical uniformity, Blackpink still stands out from other girl groups when each member's outfits show off their own individual style Blackpink attracts international attention. When wearing an innovative version of a traditional Korean outfit "How You Like That.

the writing is fluent, emphatic and eloquent. Good job!

I'd like to recommend that the word "achieved"  in line 2 can be replaced with "gained".

What do you usually do in your free time? Each person has a different taste. I love listening to music, watching movies and surfing the web in my free time. Music makes me feel relaxed and comfortable. I often listen to light or playful songs. While listening to music I usually do housework so as not to waste time. From time to time I will select unique love movies to watch. Watching movies I can experience many different emotions. I often watch Chinese series. Sometimes I will online facebook to chat with my friends and read information on this social network. Today, facebook gives users a lot of interesting experiences, so I love it. The study time is stressful, so your free time can be used for fun or doing things that you love.
