Exercise #3: Using Commas in Writing
Directions: Insert commas where they are needed in the following paragraphs.
Hunting whales seems unthinkable to us doesn’t it? Well earlier in the history of our
country whaling was an important industry. In the 1600s the colonists hunted right whales off
the Atlantic coast. By the end of the 1700s right whaling had declined and sperm whaling
had expanded throughout the Atlantic and into the South Pacific. Sperm whales produced
three valuable products: sperm oil a fuel for lamps; spermaceti an ingredient in candles; and
ambergris the base for expensive perfumes. Whaling was a profitable respectable business.
The 19th century saw a change in whaling. Lured by the dream of striking it rich in the
California gold fields young men who had formerly signed up for whaling crews headed west.
During the Civil War many whaling ships were sunk by the Confederate forces. Finally with
the rise of the U.S. petroleum industry the late 1800s whaling declined even further. Today
Americans no longer hunt whales but instead work to protect them.
Exercise #4: Using Commas in Writing
Directions: Insert commas where they are needed in the following paragraph.
The sleek beautiful clipper ship is perhaps the best-known sailing ship built in the 1800s.
Prized for its speed the clipper ship had a slender hull and up to six rows of sails on each
mast. Its name was a derivation of clip, meaning “to move swiftly.” Indeed it could move at
a top speed of 20 knots. Clipper ships carried tea from China wool from Australia and
passengers and supplies to the gold fields in California. From New York on the East Coast
the clipper ships could sail around the tip of South America and dock at San Francisco in
about 100 days. The greatest designer of these ships was Donald McKay a Canadian. At
his shipyard in East Boston Massachusetts McKay constructed over 30 ships. One of them
Great Republic was the largest such boat ever built. Sailing on such a ship would be quite an
adventure don’t you think?
