instead of neatly clarifying human evolution, the finding is adding new mysteries. In a paper in the journal Nature, scientists reported Wednesday that they had saved ancient human DNA from a fossil dating back about 400, 000 years, shattering the previous record of 100, 000 years. The mismatch between the anatomical and genetic evidence surprised the scientists, who are now rethinking human evolution over the past few hundred thousand years. It is possible, for example, that there are many extinct human populations that scientists have yet to discover. Right now, we’ve basically generated a big question mark, ” said Matthias Meyer, a geneticist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and a co-author of the new study. Hints at new hidden difficulties in the human story came from a 400, 000-year-old bone found in a cave in Spain called “the pit of bones”. The scientific team used new methods to extract the ancient DNA from the fossil. Finding such ancient human DNA was a major advance, said David Reich, a geneticist at Harvard Medical School who was not involved in the research. “That’s an amazing, game-changing thing, ” he said. When Dr. Meyer and his colleagues found ancient human DNA inside they thought that it would be a very early Neanderthal, ” Dr. Meyer said. But the DNA did not match that of Neanderthals. Dr. Meyer then compared it to the DNA of the Denisovans, the ancient human lineage that he and his colleagues had discovered in Siberia in 2010. He was shocked to find that it was similar. Everybody had a hard time believing it at first, Dr. Meyer said. So we generated more and more data to nail it down. The extra research confirmed that the DNA belonged on the Denisovan branch of the human family tree.

It is almost impossible to imagine the modern world without medicine. The word medicine is derived from Latin and means ‘the art of healing’. Being an ancient science, medicine has always helped to cure people from dangerous diseases.

The main aim of medicine is not only to treat the illness, but also to diagnose and try to prevent it. Contemporary medicine is so advanced that doctors can foresee the health problems of a baby yet in the womb. It became possible thanks to modern technology.

ПЕРЕКЛАД:

Практически невозможно представить себе современный мир без медицины. Слово медицина имеет латинское происхождение и означает «искусство исцеления». Будучи древней наукой, медицина всегда лечить людей от опасных заболеваний.Основная задача медицины не только излечить болезнь, но также выявить и предотвратить её. Современная медицина настолько усовершенствована, что врачи могут предвидеть проблемы здоровья у ребенка ещё в утробе матери. Это стало возможным благодаря современным технологиям.

Library is one of my favourite places. It’s a place where you can find lots of books on various subjects, magazines and sometimes old newspapers. If a library is well-stocked, it’s an asset to every school, college or university.

Our school also has a library, but it’s not large. When I have free time, I often visit it and look for interesting books to read. All books are kept and arranged properly, so it’s not difficult to find what you need. Besides, the librarians are always there to help you. В нашей школе также есть библиотека, но она не большая. В свое свободное время я часто бываю там, в поисках интересных книг для чтения. Все книги расположены и хранятся в нужном порядке, так что вовсе не сложно найти то, что вам нужно. Кроме того, на всегда приходят библиотекари.

There are also some libraries in my neighbourhood. My favourite place is the library of Italian literature. I’m fond of Italian and I’ve been learning this language for several years. I know that attending this library is a good way to master my language skills. Apart from books in Italian, one can find other international literature in different languages, for example, in French or in English. The rooms of this library are light, spacious and well-equipped. В моем районе также есть несколько библиотек. Больше всего мне нравится библиотека итальянской литературы. Я люблю итальянский язык и изучаю его вот уже несколько лет. Я знаю, что посещение этой библиотеки хороший улучшить мои языковые навыки. Помимо книг на итальянском, там можно найти и другую международную литературу на разных языках, например, на французском или на английском языке. Помещения в этой библиотеке светлые, просторные и хорошо оборудованные.

Nowadays, there is also a possibility to read books in electronic format. In my opinion, it’s one of the best and most interesting libraries in our area. Whenever I come here, there are different exhibitions of books, pictures, photos. Sometimes, there are also lessons for the little ones, where they can hear a fairy-tale, draw a dragon or make a castle. В настоящее время существует также возможность читать книги в электронном формате. На мой взгляд, это одна из лучших и самых интересных библиотек в нашей округе. Всякий раз, когда я прихожу сюда, здесь проводятся различные выставки книг, картин, фотографий. Иногда, здесь проходят уроки для самых маленьких, во время которых они могут послушать сказку, нарисовать дракона или слепить замок.

I think that libraries are very important for people of any age. First of all, it’s the great means of education. Secondly, we can get lots of useful information there. And, finally, it just feels good to spend time in a place where nobody disturbs you when you’re reading.
