5. Write about the things we should do to save energy (50 - 60 works)

   Every day, everyone uses a lot of energy such as water, gas, electricity,... but these sources of energy are limited and they will be run out one day. So we should save them. To save energy, there are a lot of ways: Firstly, we should turn off the lights, TVs or fans when we don't use them to save electricity. Secondly, we should use shower instead of bath to save water. Besides, we should go to school or go to work by bikes or public transports to save petrol... If we save energy, we will not only save money but also save natural resources.

*Dịch:

  Mỗi ngày, mọi người đều sử dụng rất nhiều năng lượng như nước, gas, điện, ... nhưng những nguồn năng lượng này có hạn và một ngày nào đó chúng sẽ bị cạn kiệt. Vì vậy, chúng ta nên cứu chúng. Để tiết kiệm năng lượng, có rất nhiều cách: Thứ nhất, chúng ta nên tắt đèn, TV hoặc quạt khi không sử dụng để tiết kiệm điện. Thứ hai, chúng ta nên sử dụng vòi hoa sen thay cho bồn tắm để tiết kiệm nước. Bên cạnh đó, chúng ta nên đi học, đi làm bằng xe đạp, phương tiện công cộng để tiết kiệm xăng dầu ... Nếu chúng ta tiết kiệm năng lượng, chúng ta không chỉ tiết kiệm tiền mà còn tiết kiệm tài nguyên thiên nhiên.

5.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.Because of green-clean-beautiful envinroment
