帮忙修改一份自我介绍
Good morning, everyone, Here I 'll introduce myself. My name is xx. You can call me xx. I am coming eighteen. I am changeable, just like the weather. Sometimes I'm cheerful but sometimes I'm gloomy. There are 4 people in my family, including my father, my mother my elder sister and me. I have lots of hobbies, such as reading, singing traveling and so on and I like the Internet and pop music alone in my home. I especially like traveling. Because there’s an old Chinese saying: "It's better to travel 10000 miles than to read 10000 books."So, traveling really opens you eyes to other cultures. About study, I am not good at math and English. But they are important subject. I must work hard with them. Therefore it is a very annoying. Although my English is very poor, I still want to study well. After graduation, I want to continue my study. If I can, I will not go to the local university. I prefer to choose university, where are the mainland of china. In the future, I wish I will speak English well.
