Game Lover Finally I started to write my everyday essay. Today I want to talk something about computer games. Yeah, though as a girl, I am a game lover. I really enjoy that, and with no doubt, I spend much time on that. That's why I didn't write yesterday, and that's why I am here so late today. The game I am currently playing is Dragon Age. It is not a new game but a classic one. I love RPGs, especially those in which I have choices and can somehow decide "my life", decide the final ending. By the way my favourate one is the Elder Scroll. I am really engaged by the beautiful scene and abundant interactions. I also love Real Time Strategy, like Red Alert, which is the first game of mine. Sometimes I will think, why I just love to play PC games so much? I know there are many people around the world play games, but, do they, or do we, have the same reason? Maybe for someone is a good way to relax, maybe it makes you feel proud and achieve something, and maybe you just like the ideas, the image or the figures. Those are all good reasons. For me, the most important thing is, to experience, and to explore. It's the feeling like you live another life.All those NPCs, they have their own feelings and thoughts in my mind. They are alive, just the way as what I have imagined. That's really amazing. So that's why I have a little bit strict taste of games. I only choose those ones which could tell complete stories. Sometimes I even wish to live in the virtual world for a while. However, I have to admit that it really cost time to play big games. I always miss my tasks, fail to finish my plans, and sleep late so feel tired. So it's also a time for me to manage myself better. I am not a,little girl anymore and I must accomplish my goals and spend time with families and friends. That's what I should mention myself in the future. So, this is my feeling about PC games. Please help me to revice that and it will be appreciated. And tell me, what's your opinions on that?

In this picture, what is a father showing his little boy how to use? I saw this sentence in an oral English training book. But it seems quite strange to me. I just wonder if it is common to say like that? And if not, what should I say instead? The Chinese meaning is 这张照片中，父亲在给孩子展示什么东西的使用方法？ Thank you very much!

First day here Hello everyone I am Starry. I am a new one here. Though I have been learning English for more than ten years at school, I still feel puzzled sometimes and fail to use it properly as a second language. That's why I decided to start further study using some books, software and website. I am practising British accent now, through the book Cambrige English Pronunciation in Use. It's not very easy but I'll try my best. The best way to learn a language is to use it. So I also use some apps to force myself thinking and talking in that every day. And now I decide to write a short essay every day to perfect my writing skill. Maybe one topic for each day? I am on my way! Hope it makes sense! I also begin to learn German these days, just as a hobby. Learning different languages is amazing! I am willing to have language exchange with some native speakers. So are you intetested in learning Chinese? It may seem difficult, but worth trying. I love my culture and wish to share with you! More information about myself: My major is medicine so if you happen to learn it as well I wish we could exchange our ideas. I love music and games. And I am interested in literature. So that's all for the first day! It is raining outside. Hope it will be a good begining!
