"In the past, people didn't think children will => would be ones=>the ones building => to build a country. However, in the future, this view will changed=>change. Teenagers are => will be the next generation, who will be controlling and running the world someday. As a result, teenagers play an important role in society. What they do, what they accomplish, what they are exposed to has every effect on, not only our personal future, but the future of society as a whole. If they develop well, study hard and are always creative, their community will be getting more and more modern. Clearly, every generation grows up in a completely distinct world. The prosperity of a country in the future depends on the teenager generation. As teenagers, we need to have faith and power within ourselves. We need to have initiative. We are in charge of the future generations. If we don’t make a change ourselves, how will improvements in society occur?"

We can save energy by doing some following tips. First of all, we should use electricity more efficiently and reduce our electricity bill. We need to turn off the TV when we are not watching, turn off all the lights before going to bed. Besides, we should not leave the fridge door open in a long time due to wasting of electricity. Moreover, we should save water by taking showers instead of baths or turning off the water when you don not use it. The next tip is reducing the use of fossil fuels like gas, coal, and oil. It is not only saving energy but also protect our environment. To do this, we can use public transport and avoid using car or motorbike for short trip. All in all, because our energy is limited we need to reserve it for the future generations.

Many poets and writers have taken young age, took young people to be the subject of their essays and poems. In the past, there were so many heroes for the country of the Vietnamese nation that they were not afraid of difficulties and discharged themselves because of their independence and freedom. Especially there are heroes who died when they were very young. So, the question here is how young people today need to be responsible to help the country prosper like the old seniors ? To help the country develop, young people first need to work hard to study hard to have a solid knowledge. Secondly, young people must have the right direction for their future careers to be able to build up their home countries in the direction that best suits their abilities. And furthermore, you need to work hard to be able to devote yourself in and out at any time. In general, the help, dedication, and home country are always the most necessary things in each era.

UFOs, or unidentified flying objects, have sparked curiosity and debate for decades. While some believe in their existence due to reported sightings and unexplained phenomena, others remain skeptical, citing lack of concrete evidence. Personally, I remain open-minded, acknowledging the possibility of unexplained aerial phenomena while awaiting scientific validation.
