Leaving difficult words aside way

In the future, I'd like to take an English proficiency test, Eiken or TOEIC, to know my proficiency in English but it's to be further ahead because I have many things needing to learn.

At first, I need to be proficient in making various sentences using easy words as much as possible because I hope to be able to tell in English almost anyone who doesn't know difficult words. After doing that, I'll take difficult words into myself, little by little.

My first goal is to read something in English: news, essays, books, etc.
However, the writing skill is essential to read. I come to know how to read sentences by writing various. That's as understanding the grammar. In addition, the speaking skill is necessary to write. Probably, pronunciation easily in speaking is related to the choice of words.

The second goal is to listen to something in English.
Also, the speaking skill is essential to listen. That's as understanding the pronunciation. I probably think it is even more important for listening to know the timing of each sound than to pronounce them perfectly right.

Even if I reach here through the easy level, I have many to do.
So, I leave difficult words aside way for a while.
