     "How can I learn English well?" This is a question many students ask. In my opinion, the most effective

way is to learn lessons by heart. If you can recite the text and write it out, you've learned it fairly well. And

if you can retell, in your own words, what the lesson is about, you're a very successful learner indeed. Your

English will be quite perfect. This is a difficult task. However, if you try to learn by heart only part of each

lesson, you'll find it not so hard as you might have expected.

     Learning this way, you will make rapid progress. Of course, writing is also necessary. It helps you a lot

on your way to success in English.

     Equally important is to feel the language. You should be able to laugh at jokes and be shocked at bad news.

When using English, try to forget your mother tongue. Instead of helping you, your own language gets in your

way. So, never try to see English through translation.

2. "Instead of helping you, your own language gets in your way." This sentence means that memorizing your
