GRAMMAR AND VERBS (20 MINUTES)
Grammar
The grammar for this lesson is articles and proper nouns. An article is a special type of adjective. "A", "an" and "the" are articles. In sentences, articles are always placed before a noun. A proper noun is a special type of noun. It is the name of something and always starts with a capital letter.
Articles
There are two kinds of articles: indefinite and definite. “A” and “an” are indefinite articles. Definite. "A" and "an" are indefinite articles. Use indefinite articles when talking about something singular (one thing) in general. For example:
I want an apple. (any apple)
A cheetah is a kind of cat. (cheetahs in general)
Note that you do not use articles in the expression "kind of." You say "a kind of cat," you do not say "a kind of a cat."
Give the rule for using "an" instead of "a. ""An" is used for words that begin with vowels: A, E, I, O or U. It makes them easier to pronounce. For example:
an animal
an eraser
an idea
an orange
an umbrella
The" is a definite article. Use definite articles for the following situations:
1. When talking about something mentioned earlier. For example: He picked up a book and read the book.
Note that the article "a" is used with the first mention of "book", but the article "the" is used with the following mention of "book."
2. When talking about something that the listener knows. For example:
Open the door please.
In this case, you are not talking about any door.
You are talking about a specific door. The listener knows which door you mean.
3. When using with certain proper nouns. For example: The ship sailed on the Pacific Ocean.
In this case, we say "the" Pacific Ocean, not "a" Pacific Ocean. Why?
Because there is only one Pacific Ocean, although it is one of many oceans.
4. When using with plurals of nouns. For example:
A black cat is at the door.
BUT, the black cats are at the door.
