For each set of words, try to head-copy it. First, the words are sent in Morse code. Then it is spoken. And finally, it is sent again in Morse code. If you missed it the first time when it was sent, the second time allows you an opportunity to learn the words.
N-Grams are a stepping stone in head-copying entire sentences. These word groups should seem familiar and common to any English speaker.
N-Grams in this context are sequential words found in a sentence where n is the number of words found in the sequence. This practice file contains the top 250 8-grams found in contemporary English. (Negative and inappropriate n-grams were removed. And n-grams with many uncommon words were removed.)
