I am a high school student. I go to school every day from Monday to Saturday. I am very busy with my studies. Sunday is my holiday. On Sunday morning, I get up later than usual. After breakfast, I come to my close friend’s and we often go shopping in the downtown areas. Sometimes we go on a picnic in the countryside. In the afternoon, I prefer having a rest in my room, reading books or listening to pop music. Then after dinner, I prepare my lessons for the following weekdays and go to bed early. Once in a while, I spend my weekend joining the social activities organized by the Ho Chi Minh Communist Youth Union of my school. We usually go along the streets raising money for charity or travel to remote areas to give help to poor people. Sunday is a good time for me. It refreshes my mind after a week’s hard work.

[5] [Also, teachers or lecturers can make their lessons or lectures more lively and interesting with programs such as Powerpoint or other types of slide-show]. [6] Lastly, for entertainment, after working hard we can get relaxed by playing some computer games or listening to our favorite type of music with the computer. When we want to see a movie, staying at home, we can search for it on the Internet just in term of minutes, without having to go to the theater or somewhere to buy videos tapes or CDs. [7] It goes without saying that the computer plays a key role in every part of our daily life, from businesses to education or entertainment. [8] With it, everything in life would slow down and life would no doubt be much more dull.2.

Perilous pollutants may contain various types of impurities including harmful chemicals, dissolved gases, suspended matters, dissolved minerals, and even microbes. All the contaminants reduce the level of dissolved oxygen in the water and affecting the lives of animals and human beings to a great extent. Dissolved oxygen is the oxygen present in water required by the aquatic system to continue the lives of plants and animals. However biochemical oxygen is the demanded oxygen by the aerobic micro-organisms to oxidize organic matters of wastes. Water pollution is caused by two means, one is natural water pollution ( due to the leaching of rocks, decay of organic matters, decay of dead matters, silting, soil erosion, etc ) and another one is man-made water pollution ( due to the deforestation, set up of industries near large water bodies, high level emission of industrial wastes, domestic sewage, synthetic chemicals, radio-active wastes, fertilizers, insecticides, pesticides etc )
