Topic: TV and the speed of my 600-word composition! ! (Second grade composition)

I like watching TV since I was a child, and colorful TV programs often make me laugh and forget all about eating and sleeping. Watching TV has opened my eyes. I have learned a lot of great events, small things, wonders and interesting things that I can't learn from books and see in real life. It really enriched my thoughts and increased my knowledge. For example, during the summer vacation, I watched the TV program that China hosted the Olympic and Paralympic Games for the first time. It's wonderful and touching. As primary school students in the capital, let us be proud of our motherland and cheer for the athletes. I am even more excited and proud to watch Shenzhou VII and the astronauts walk in space. China is amazing! The development of science and technology challenges the limit. All this knowledge was acquired because of television. How else would I know? Every time I think of it, I can't help but admire it; Television is really a treasure. Everyone knows all the important events in the world.

Just when I thought ordinary TV was enough to enjoy, I didn't expect the teacher to tell us again: "There is a cable digital TV in our country. Moreover, in eleven urban areas of the capital Beijing, more than10.5 million residents have started to use cable digital TV. " Digital TV? It's so fresh. In my mind, there are digital cameras and digital cameras, and now there is digital TV? It attracted me like a magnet and made me interested in this new product. I am determined to find out the "identity" of this digital TV. So I began to get busy, looking for information, asking teachers and searching online.

Digital TV is a new way to watch TV. As long as you enter the cable TV network and install a machine called "set-top box" next to the TV at home, you can watch digital TV. This makes ordinary TV become a digital multimedia information terminal integrating "information, service, culture, entertainment, communication and interaction", which can compress the current TV programs into digital signals, make room for inputting and storing hundreds of programs, and let you choose at will. In this way, we can not only watch more and better programs, but also enjoy the rich contents of timely and accurate government information, program guides and life information, with high definition and stable picture quality. At the same time, you can also enjoy the audio-visual effect comparable to that of DVD, which simply integrates all the functions of TV, computer and DVD. Wow! It's amazing.

Digital TV is so advanced, so practical and so attractive that I can't wait to have it at once and operate it in front of the TV. Look at what is useful for my study and growth. Hey, when can I have it at home? I hope that once that magical set-top box patronizes my TV, my dream will come true!
