Even on a good day, proofreading our own work is a tricky job. We're inclined to see what we want to see, and usually what we don't want to see are our mistakes.
Practice in proofreading the work of others can help us become more aware of our own occasional slip-ups. This exercise offers practice in distinguishing some of those troublesome words that closely resemble other words--homonyms and homophones. (Here's a tip: to view these exercises without ads, click on the printer icon near the top of the page.)
First, see if you can spot and correct the four homophonous errors in a paragraph adapted from Bill Bryson's witty travel book Neither Here Nor There:
CowsThe four troublemakers are highlighted (and corrected) in Bryson's original paragraph on page two.
To my mind, the only possible pet is a cow. Cows love you. They are harmless, they look nice, they don't need a box to crap in, they keep the grass down, and they are so trusting and stupid that you can't help but loose your heart to them. Where I live in Yorkshire, theirs a herd of cows down the lane. You can stand by the wall any hour of the day or night, and after a minute the cows will all waddle over and stand with you, much to stupid to know what to do next, but happy just to be with you. They will stand there all day, as far as I can tell, possibly till the end of time. They will listen to you're problems and never ask a thing in return. They will be your friends forever. And when you get tired of them, you can kill them and eat them. Perfect.
If that one was too easy for you, try catching and correcting the five common errors in this paragraph.
How to Build a Fire in a Fireplace
Though "experts" differ as to the best technique to follow when building a fire, one generally excepted method consists of first lying a generous amount of crumpled newspaper on the hearth between the andirons. Kindling wood is than spread generously over this layer of newspaper and one of the thickest logs is placed across the back of the andirons. This should be as close to the back of the fireplace as possible, but not quiet touching it. A second log is then placed an inch or so in front of this, an a few additional sticks of kindling are laid across these two. A third log is then placed on top to form a sort of pyramid with air space between all logs so that flames can lick freely up between them.
Again, you'll find the corrected version of the paragraph on page two.
