This sentence-imitation exercise will give you practice in applying our Top Four Guidelines for Using Commas Effectively.
Instructions
Use each of the four sentences below as the model for a new sentence of your own. Your new sentence should follow the guidelines in parenthesis and use the same number of commas as in the original.
Example: The younger children spent the afternoon at Chuck E. Cheese, and the others went to the ball game.
(Guideline: Use a comma before a coordinator--and, but, yet, or, nor, for, so--that links two main clauses.)
Sample sentences:
a) Vera cooked the roast beef, and Phil baked a pumpkin pie.
b) Tom ordered steak, but the waiter brought Spam.
Model 1: I rang the bell and pounded on the door, but no one answered.
(Guideline: Use a comma before a coordinator--and, but, yet, or, nor, for, so--that links two main clauses; do not use a comma before a coordinator that links two words or phrases.)
Model 2: I sent Elaine a basket full of apricots, mangoes, bananas, and dates.
(Guideline: Use commas to separate words, phrases, or clauses that appear in a series of three or more.)
Model 3: Because the storm had knocked out the electricity, we spent the evening telling ghost stories on the porch.
(Guideline: Use a comma after a phrase or clause that precedes the subject of the sentence.)
Model 4: Merdine LeVoid, who has never voted in her life, is running for the post of county commisioner.
(Guideline: Use a pair of commas to set off nonessential words, phrases, or clauses--also called nonrestrictive elements--that interrupt a sentence.)
