Today, more and more high school student publish their own blogs on the Internet. For one thing, it can provide colorful platform to show their talents, and for another, it is also a way to release their pressure. And this make it popular to high school students. But many parents and teachers hold a same view, and they think that managing a blog will take a lot of time and energy, while this should be used study which is their main duty. Personally, I do approve of this activity. Open and organizing an eye-catching blog needs various abilities such like writing, designing and so on. Only if that we have those abilities can we make a good blog. And also, we can improve themselves during the procedure of organizing our blogs.
Last Sunday my father and I went fishing along a river. We found the water very dirty that we could hardly catch any fish in it. A lot of factories along the river always poured their waste water and rubbish straightly into the river, which made the river polluting. In this way most of the fish in the river was killed. Unless the rivers all over the country are polluted like this, no living things will be exist in the water. As we all know, environmental pollution do great harm to living things. Now more and more people have realized what serious this problem is. Our government is doing her best to take measure to fight against pollution. We expect that water in every river will be made cleaner and cleaner before long.
This term I’m very busy with a heavy load of lesson. Sometimes my math homework took up too much time that I could only spend a few time on English words. One day, my English teacher gave us a test, and I was complete puzzled. I suddenly had an idea: look up for the new words on the Internet on my mobile phone. Went through the words quickly, I was secretly delighted with my little game while someone tapped me on the shoulder. It was my English teacher! She was staring at me! I knew that it was the kind silent warning. She felt ashamed and was determined never cheat in the test again!
Dear editor,
I am a high school student. A few days before, one of my very good friends told me that he was going to stop the school. He said that he want to start his own business. I tried my best to get him change his mind, but failed. I know it is difficult of him to change his mind. He is not doing so good in his studies, yet I want to insist that I give it a try. The process is more important than the results. Now there are only 90 days leaving before the test. I am not sure that his decision is right or wrong. I needed your advice.
