Because the text makes sense, you can read ahead in phrases rather than single words. That's exactly the skill that makes experienced typists fast.
Why practice with paragraphs?
Typing tests for jobs usually use passages, not word lists. Paragraphs also teach you to keep a steady rhythm through long words, commas and sentence breaks. If your paragraph speed is much lower than your word-list speed, practice punctuation and capital letters.
Read ahead, don't spell
Beginners look at one letter at a time. Fluent typists look at the next word, or even the next few, while their fingers finish the current one. Try keeping your eyes one word ahead of the caret - it feels strange at first and then suddenly clicks.
