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.

Keep animals without "the". What is that " 's " for in the second sentence

"Taking care of animals" instead of  "Care about animals"
"teaches children to be more responsible " instead of "learns a child responsibility"

I corrected the text and it looks like that.
. 
Many parents allow their children to keep animals in their  house. For children this is an entertaining and  funny game.

I would like to express my opinion on this problem. I think it is a good idea. Firstly, caring about animals teaches a child to be responsible. Secondly, friendship with pet which exists from childhood teaches children to love and respect  animals.
On the other hand, a lot of parents believe that young children cannot take good care of their pets and pay them enough attention.
I do not agree with this opinion because it is essential for children to learn to be responsible for another's life.
In conclusion, I think that looking ater pets from an early age is a good idea. Pets are very good friends of children.

Seems that you confuse learn and teach

learn - учиться
teach - научить
