Dear friends，Do you want to live in a beautiful world? Living a low-carbon style of life is playing a more and more important role in energy saving and environmental protection. To fulfill it, we should bear the following in mind. First, its important to turn off taps and lights and recycle everything recyclable in our daily life. Whats more, while sticking to the habit of setting the temperature of your air conditioner at above 26 in summer and eating fruits and vegetables in seasons, we should also climb stairs under the fifth floor instead of taking lifts. Lets all take action now and contribute to the prosperity of our motherthe earth. Thank you!This passage is about a little hero. Being an orphan, he lived a hard life in early years. He helped the captain and his soldiers but lost his very young life for his country. After listening to “A Little Hero”, I was moved and encouraged .The little hero was homeless. He had neither parents nor brothers nor sisters. He lived a poor and hard life by working for another family in his early years. He didnt study at school, but he loved his country. Compared with the little hero, I had a happy childhood. I have a happy family with many good books, TV, two computers, a car and so on. My mother is a nurse and my father is a teacher. I have a ten-year-old brother. We are studying at school. At weekends, we often play basketball, play the computer games or go shopping. We can enjoy traveling in our summer holidays. As a high student, I should study hard to be a scientist. I will make my contributions to my motherland.
