My school is spacious and comfortable. It is in a three- floor building. Pupils can walk on foot or take a bus to get to the school. As a rule, there are about twenty-five pupols in a class. Our classroms are big and cosy. There are portraits of famous scientists and writers on the walls. Also, there are posters with information on school subjects. Children and teenagers are diligent and motivated and teachers are strict. So, there are no problems with discipline. Here is the list of some subjects taught at my school: Russian, Literature, Math, Geography, History, Science, Chemistry, Physics, Biologu, Craft and PE. If a pupil wants to get more information on s subject, he or she can attend extra classes. They are usually taught at school every afternoon. All pupils at my school must wear a uniform. It looks nice and fits well, so everybody likes it. We can also have lunch at school. Lunches are decious and tasty that's why many schoolchildren eat here.
1. Text 5 goes under the title "Phosphorus" and describes this element in the Periodic Table in great details. 2. The author gives many interesting facts concerning the properties and peculiarities of phosphorus and compares it with (w/) nitrogen. 3. Firsly, phosphorus and nitrogen have much in common, but they also differ greatly. 4. While nitrogen is quiete inactive under ordinary conditions, phosphorus reacts rapidly both w/ metals and non-metals. 5. At ordinary temperature, nitrogen is a gas, and phosphorus is a solid. 6. Secondly, phosphorus has the following properties: - it is almost insoluble in water; - it dissolves in many solvents. 7. The article goes on that phosphorus exists in several aliotropic forms, only 2 of them are of general interest. One is white phosphorus. 8. The most striking property of white phosphorus is its activity w/ oxygen. 9. It is very combustible, that's why it must be left under water. 10. The author gives some measures of precaution while handling white phosphorus. 11. They are as follows: - never handle white phosphorus w/ bare hands; - always remember that it's very poisonous, it may cause chronic poisoning. 12. In the conclusion, it should be mentioned that red phosphorus is a more stable form. It isn't so combustible, but the products formed are the same produced by white phosphorus. That's about all;-)
