A study of ancient coral reefs has revealed that the weather phenomenon known the (1) El Nino was most intense during the 20th century. El Nino, which has been present for (2) the past 130,000 years, is an atmospheric phenomenon occurring in the Pacific Ocean. It is known to contribute to (3) climatic disturbances along the western coast of Peru and Ecuador on (4) account of exceptionally warm ocean conditions it brings to (5). El Nino, which stands for (6) ‘the child' referring to (7) the infant Jesus Christ, appears in the regions every December around Christmas. Every three to seven years, El Nino brings about (8) being really severe and intense weather conditions. The disturbances strike when the warm ocean currents result in (9) a reversal in the normal weather conditions of the eastern and western Pacific. El Nino is responsible for (10) changes in the wind pattern, temperature of the air and the sea surface, which in (11) turn culminate into (12) heavy rainfalls in South America as well as (13) droughts in India and southern Africa. It is now said that El Nino can influence the climate of more than half the earth. It is also blamed for (14) recent droughts and floods in Australia. Researchers claim that El Nino's activity was never so (15) acute as during the last hundred years. Its intensity has been on (16) the increase since ice ages. The popular view is that El Nino's intense impact may be related to (17) global arming and emissions of greenhouse gases. Although there is no sufficient evidence to back up (18) the assumption, it is common knowledge that a great many global changes have come about (19) in climate ever before (20) the temperature on the planet started to increase.

Many in the world of professions. They are different, many-sided. Each is necessary, each people need. And each can be protected in its own way. Sometimes a man dreams of becoming an actor, singer, artist, and becomes operational, a teacher, or a journalist. But this does not mean that he gave up his dream. It can be more actor-Amateur, save the love for singing or painting, but also improve it.
My mom's a wonderful profession, it is necessary and scientists, and workers. My mother is a librarian and bibliographer. She worked in the library of one of the enterprises, but now work in the service of information one of the factories of our country for 23 years. She likes her job. This work with books.
Not knowing how to work with the book, the student is not to write a good essay, work does not pass the exam on the category, the engineer will not be able to develop a new design of the machine, the scientist will not be able to work on the necessary problem. For a scientist need in the huge flow of information to find the pearl of the necessary material. All of this is able to carry out my mother. She conducts the required search information for researchers, helps in the development of new constructions of cryogenic engineering.
Some are unaware of the work of an engineer in information activities. My mom looks great flow of information, by selecting the crumbs of the material, she acquires a card-index of subject of the enterprise, watching their recruitment and organizes them.
Mom carries out the search of information on a particular topic, necessary for work, the most relevant. And it means browse sources of information (a few of the titles) for 20, 30, sometimes 50 years, by selecting from the number of the most actual. After that the sampled material is arranged in sections, systematized in alphabetical order, after which it is published and distributed in the country to those enterprises, which deal with related issues.
Mother helped also to inventors. In addition, she still patent agent. It may be necessary to pick up the issue of the patent material (copyright certificates and patents) of different countries.
I very love my mother, and I like it interesting and useful to people profession.

Idecided to be a journalist. i think it is an interesting and useful profession. i like to watch tv, listen to the radio, read newspapers and magazines. i like everything which connected with mass media. i have a hobby. my friends and i are publishing a small newspaper once a month in our school. we write articles about school events, life of young people, jokes, draw pictures and caricatures. my favourite school subjects are history and literature. i like the profession of a journalist. they meet many people. they try to understand what is going on in the world, or the country, or the city and try to explain it to other people. i think that the work of a journalist is very much like that of historian. a historian studies and tries to explain events of the past and a journalist does the same about the present. but for me to be a journalist is much more interesting than to be a historian because you deal with real events that are happening right now so you can even influence them. so journalists can influence the history. that is why i want to be a journalist.
