The cycle English vocabulary automatically reads English words and meanings, making it easy to study English words and listen. In particular, it is a vocabulary learning method that utilizes the principle of short-term memory because it can learn at least 5 cycles before it disappears from memory through cycle repetition. If you set it to cycle 5, you hear words 1,2,3,4,5 and 2,3,4,5,6 words 3,4,5,6,7 words 4,5,6,7 To play words 8, 5, 6, 7, 8, 9 and 6, 7, 8, 9, and 10, you can study the recently learned words over and over 5 times, so you can use them with confidence. If you do, you can produce good results.
