is an exercise to help you understand the usages of "the" (specific),
"a/an" (one), and pluralization of nouns in English. I will give
you several examples, each followed by exact meanings and then we can see
how many you can do.
Rules: There are two nouns and one verb. These nouns can interact with each other, using the given verb. You may create as many sentences as possible, if you can follow them by EXACT meanings. The sentences can ONLY be in the simple present or present continuous. You may only use the words the, a, an, or no articles (Ø) and make the nouns singular or plural. No other tenses can be used, no words can be changed and no extra words can be added. Either noun can be the subject or object:
1. The dog chases a cat.
A particular known dog is in the habit of chasing an unknown or unseen cat.
2. The cat is chasing a dog.
A particular known cat is now chasing an unknown or unseen dog.
3. Dogs chase cats.
Any dog can or may chase any cat at any time.
4. A cat chases the dog.
An unknown or unseen cat is in the habit of chasing a particular known dog.
5. The dog chases the cat.
A particular known dog is in the habit of chasing a particular known cat.
6. A dog chases a cat.
A. Any dog can or may chase any dog at any time. B. An unknown or unseen dog is in the habit of chasing an unknown cat. (However, I hear them at night!)
Now, let's see how many you can do. Guess how many possibilities there are. You will need more paper!
