I think that the best method of taking high score for TOEIC is acquiring the speed reading and vocabulary power. Because TOEIC has a lot of problems compared with time. So we should efficiently deal with the problems in time. For that,　the two abilities are necessary for us. What we should do to acquire the speed reading power is reading English without translating into Japanese even in your mind. This means that we have to read English text as English itself. That might seem to be difficult first for you but if you do so repeatedly, sooner or later, we will be able to read English faster than what we were. To raise our vocabulary power is to be in environment surrounded by English text. And examine, write, pronounce the English words which you do not know until we remember the words.
