Nowadays, energy is being run out more and more so it is one of the most important things of our life. We need to save energy because nobody of us can lives without energy. So why don't we start to do it right in our home? We have many ways to save energy in our home. One of those ways is using electricity, water and gas economically. Such as we should turn off the light in room when we go out or in unnecessary situations, avoid wasting water, shut the kitchen stove when stop cooking. Use a microwave instead of a stove to reheat food. Use rechargeable batteries instead of disposable batteries... Besides, we should use electrical equipments which are energy - saving. Such as using lights and fans that have low capacity, or using equipments which reserve electricty. Not only do these help us to save money but also they work effectively.
In addition, we should frequently check electrical equipments in our home in order to fix opportunely. In summary, we need to save energy so that energy isn't run out and continues to serve human's life.

Dear Oanh,Thank you very much for your letter which arrived a few days ago. It waslovely to hear from you. I am sorry, I haven’t written for you such along timebecause I studied hard to pass the final exam. However, I had agreat weekendmore than every when I went to live concerts last night with my friends. Now, Iam writing to tell you how the wonderful concert is.It is the beautiful concert I have ever taken part in with many people andthe miracle of sound of piano. As you know, my pianist is Yiruma and in lastconcert I couldn’t believe that he appeared in my eyes and gave me a big hugafter his performance. I also listen a soothing music which is played by him andother professional musicians. Only when I heard his song from the stage I feelanythings around me seem to disappear and I can fly with many stars on the skyto forget all my fears which I suffered before. That is amazing.Let’s come back to my live concert. It is so cool and until now I can’tforget my feeling about it. Do you often to go live concerts? What kind of musicdo you like listening to? Who is your favourite singer?I am glad if you tell me about it in the next letterI look forward to your replyYour sincerel.

My favourite is Holi Festival in India .It took place at the end of February every year.The festival is to welcome spring and to fight against the evils.Coming to this festival,people have chance to play,dance and sing.The tourists and the local people throw colourful powder to one another ,and dance under water sprinkler.People will have a wonderful vacation there.If having a chance, I will go to India and enjoy the Holi festival.
