Описание работы

The problem of stray animals in the streets is certainly something which is often discussed in today’s world. Statistically an animal is lost every 30 seconds. Thus, no one can deny the fact that it is very essential to decide if stray animals should be allowed living on the street. In my opinion, people should create special conditions for such animals and care for them more.

Advantages & disadvantages of using mobile phones (by Lena Vymmer)

There’s no doubt that mobile phones are one of the major technological breakthroughs of the last century. It is very hard to imagine our lives without them, but are they so convenient as well as safe?

To start with, the usefulness of the mobile phones cannot be denied. For instance, you can get in touch with your family, friends or colleges within seconds wherever you are. Furthermore, mobile phones provide you with entertainment such as games, music or videos which can be interesting to both adults and children.

On the other hand, there some points against using the mobile phones. The main disadvantage is that many scientists claim that mobile phones can emit radiation which can have bad influence on people’s health. Besides, due to the fact that many parents can afford to buy a mobile phone to their children, it can attract muggers, therefore putting your kids at risk.

Taking every into account it seems that mobile phones are important achievements of technology which are extremely beneficial to people’s society but only with a matter of safety. 

В наше время тема развития альтернативных способов получения энергии  как нельзя более  актуальна. Традиционные источники стремительно иссякают и уже  через каких-нибудь пятьдесят лет  могут быть исчерпаны. И уже сейчас энергетические ресурсы довольно дороги и в значительной мере влияют на экономику многих государств.

Всё это  заставляет жителей нашей планеты  искать новые способы получения  энергии. И одним из наиболее перспективных  направлений является получение солнечной энергии. И это вполне естественно. Ведь именно Солнце даёт жизнь нашей планете и обеспечивает нас теплом и светом. Солнце обогревает все уголки Земли, управляет реками и ветром. Его лучи выращивают не менее одного квадриллиона тонн всевозможных растений, которые, в свою очередь, являются пищей для животных.

Таким образом, мы уже используем солнечную  энергию в своих нуждах и все  традиционные источники энергии (нефть, уголь, торф) появились на земном шаре благодаря Солнцу.

Человек с самых древних времён учился пользоваться дарами Солнца. Даже простой костёр, который согревал наших предков тысячи лет назад и продолжает это делать теперь, является по сути дела использованием солнечной энергии, которую накопила древесина. Но Солнце способно удовлетворять и более масштабные потребности человека. По подсчётам учёных, человечество нуждается в десяти миллиардах тонн топлива.

Если  высчитать количество таких условных тонн, которые предоставляются Солнцем  в течение года, мы получим фантастическую сумму – около ста триллионов тонн. Таким образом, люди получают количество энергии, превышающее необходимые  ресурсы в десять раз. Нужно только взять это энергетическое богатство. Вот этот вопрос и является крайне актуальным для науки.

Результатом многолетней работы стало такое  устройство как солнечная батарея. 

In our time, the topic of development of alternative methods of energy production could not be more timely. Traditional sources are drying rapidly and within Some fifty years may be exhausted. And now energy resources are expensive and largely affect the economy of many countries.

All this makes our planet's inhabitants to seek new ways to generate energy. And one of the most promising directions is to get solar energy. And it is quite natural. After all, the sun gives life to our planet and provides us with warmth and light. The sun warms every corner of the earth, controls the rivers and wind. Its rays are grown for at least one quadrillion tons of various plants, which, in turn, are food for animals.

Thus, we already use solar energy to their needs and all the traditional sources of energy (oil, coal, peat) appeared on the globe by the Sun.

People from ancient times learned to use the gifts of the Sun. Even a simple fire, which warmed our ancestors thousands of years ago and continues to do now is essentially the use of solar energy that has accumulated wood. But the sun is able to satisfy the broader needs of the person. Scientists estimate that the human race needs ten billion tons of fuel.

If you calculate the amount of such conditional tons, which are provided by the sun during the year, we get a fantastic amount - about a hundred trillion tons. Thus, people are getting the amount of energy that exceeds the resources of ten. Only need to take it's energy wealth. Here the issue and is highly relevant for science.

The result of years of work became such a device as a solar battery. 

TEENAGERS PROBLEMS

  Everybody was a teenager, that’s why everybody can say that it’s very difficult to be a teenager. Everyone has different problems, but teenage problems are special.

  One of the worst teenage problems is schooling. Sometimes you feel bad because of teachers’ or classmates’ attitude to you. You are tired of studying, that’s why you don’t have energy and time for doing other things. Also I’d like to say that a lot of teens like to look older, that’s why they obtain bad habits like smoking, drinking, taking drugs, etc. But a teen can have bad habit because of problems in private life. Absence of the second half, loneliness, lack of pocket money or parents’ misunderstanding can inspire teen, that his best friend is a bottle or a cigarette. None should be angry because of teen’s feelings, because the boy or the girl often doesn’t control his or her feelings. Streets and street bands can make a teen ruder and crueler, that’s why parents shouldn’t allow their children to have such interests. I know a lot of boys and girls, who think that cleaning their room is the most important problem of humanity. They think it’s boring and useless, because the room will become dirty 5 minutes later. I think, teens who have mania to comps are very boring and uninteresting. You can’t speak with them about something beside of «Sims» or «GTA». It’s a real problem, to my mind. Every teenager has a favorite singer, writer or sportsman. But no one should become a fan, because we can kill our individuality and become clones. Sometimes a quarrel between teens can lead to serious law’s violations. It’s very dangerous! Also bad relationships between members of the family make the teen very emotional. The teen doesn’t get3 along with parents and relatives. Parents press on their child, they think he is iron and he doesn’t feel soul ache. Parents want us to study very well; they don’t understand that we do everything as good as we can. They don’t respect our interests thinking that we become strange because of music or sporty.

  I think that when a person grows and stops being a teen, he or she stops understanding us. Only teen can understand people, who are the same age as he is. It’s really difficult to be a teenager!
