English has already been a long time for quite a long time and in demand among all foreign languages. There are more than 800 million people who study English or speak on it as in a foreign language. It is because of this popularity and need, we decided to prepare a cycle of materials about an independent study of English for you. Online simulators: Use modern online simulators that have a computer form in a comfortable game form. The main advantage of such services is their availability from any place. You wait in the queue, go to the subway / bus and learn new words in parallel or train grammar on your mobile. Services: Lingualo, Puzzle English, Duolingo Online Courses: Self-study with online courses. The main advantages are structured material, the presence of homework / tests and, unlike offline courses, you are not tied by time and place and you can study at any time and almost everywhere where there is a good internet. Service: Eduget Movies in the original: A very nice way to learn the language that I personally use - watching movies, serials and cartoons. In the world, more than 85% of video materials are created in English, so you will not be sure to choose content. Confident that you have long dreamed about watching your favorite "friends", "House doctor" or "game of the thrones" in the original. Services: Puzzle Movie, Ororotv Travel: One of the effective methods of studying any foreign language is immersion in the environment. But sometimes it may be financially or organizational in charge. If you still have decided to go to relax, then my personal advice is better to choose an English-language country and (or) language school in it. This will be a wonderful combination of relaxation and practice of live English. Tutor: Often, with independent study, people lack self-motivation and a clear plan of movement to the target. In such cases, working with an individual tutor helps. Personally, I have helped me very much with the spoken language. I had a good vocabulary, but it was very hard (probably familiar to all the problem). But this issue solves only practice, practice and once again practice.

1 The internal combustion engine is called so because fuel is burned
directly inside the engine itself
2 To describe the complete cycle, let's that the piston is
the top of the stroke (top dead center) and the and the exhaust
valves are closed, When the piston
moves down the inlet valve opens to
intake a charge of fuel into the cylinder. This is called the inlet (intake)
stroke.
3 On reaching the lowest position (bottom dead center) the pis-
der,
begins move upward the closed upper part the cylinder,
the valve is closed and the mixture is compressed by the rising
piston. This is called the compression stroke.
4 Asthe piston again
the top dead center the spark plugs ignite the mixture, hoth valves he
ing closed during its combustion. As a result of burning mixtures the
gases expand and great pressure makes the piston move back down the
cylinder. This stroke is called the
reaches
powerstroke
5 When the piston reach
the bottom of its stroke, the exhaust valve is opened, pressure is re-
lensed, and the piston again rises. It lets the burnt gas flow through the
exhaust valve into the atmosphere. This is called thexhaust stroke
which completes the cycle
6 So the piston moves in the cylinder down
(intakestroke), up (compression stroke), down (powerstroke), up (ex-
hanst stroke)
