Unit 10:

In my opinion, using the alternative sources is the necessary way to solve the rapid exhaustion of our major sources of energy. The alternative sources such as solar energy, water power, wind power… are clean and safe for our life. Beside that, they are unlimited and can be renewable. Nowadays, there are some developed countries that use the alternative sources parallel the major sources of energy. Day after day, science and technology develop so fast. There are more windmills, dams are built, more solar panels are set on the roofs of houses to create energy. I think in the future, the alternative sources will replace completely our major sources of energy.

Near the end of the second semester of 4th grade, the school organized a tour for us to visit Nui Coc Lake.Because this is the first time to go away without parents, only the homeroom teacher with you so I was nervous and a bit worried. Knowing that, my mother had prepared everything for me the night before and told me everything. After that my mother made me go to bed very early because tomorrow morning 5 o'clock the car was running.I went to bed and I was still not nervous, I finally fell asleep until the alarm rang for a long time. I got up, my mother got up and prepared my backpack. After he finished, he passed me to the school yard to visit with his friends.At 5 am, the car started running, we were all happy when we passed the familiar roads. The car drove on a bon bon, only a moment later away from where we were, unfamiliar roads gradually opened before our eyes. After walking for a while, the teacher set the rhythm for us to sing familiar songs, so the whole car rang with voices and applause. The atmosphere is fun, bustling.Just over two hours later we were at Nui Coc, where the teacher gave us half an hour break for breakfast and rest. Nui Coc Lake opening before my eyes is the deep green of trees and the clear blue of the lake. The atmosphere is peaceful, quiet, different from the atmosphere where we live.
