The use of THE/ Lesson

The use of The before plural countable nouns
a. Referring to something mentioned before
In general, the has the same meaning when used with plural countable nouns as when used with singular countable nouns. For instance, the is used with plural countable nouns when referring to something which has been mentioned before.
e.g. Fallen leaves covered the ground. The leaves rustled as we walked.
In the orchard were apples and pears. The apples were nearly ripe.
The doors opened, and students and teachers began leaving the building. The students were talking and laughing.

In these examples, the first time the words leaves, apples and students appear, they are not preceded by determiners, because the things referred to have not been mentioned previously. The second time the words leaves, apples and students appear, they are preceded by the, since the things referred to have already been mentioned.
b. Referring to something when it is considered obvious what is meant
The is used with plural countable nouns when the speaker or writer considers it obvious which particular persons or things are meant.
e.g. The stars are shining brightly.
The roses are blooming.
We have put the children to bed.
I was sitting on the front steps.

These sentences give examples of the use of the to refer to things which are particularly important to the speaker or writer. The expression the stars usually refers to the stars which can be seen from the part of the earth where one lives. The expression the roses might refer to roses in one's own garden, or to roses in which one feels a particular interest. The children might refer to one's own children or to children for whom one is responsible. The front steps might refer to the front steps of one's own house.

c. Names of nationalities
The is sometimes used with the name of a nationality in order to make a general statement about the people of that nationality. A plural verb must be used in such a statement.

When the name of a nationality ends in the sound of ch, s, sh or z, the name of the nationality must usually be preceded by the.

Nationality	Example
French	The French are famous for their fine wines.
Irish	The Irish are known as poets and songwriters.

When the name of a nationality does not end in the sound of ch, s, sh or z, the letter s must be added to the end of the name when it is used in a general statement. Names of nationalities to which s has been added are often used without being preceded by the.

Nationality	Example
Argentinian	Argentinians like to eat beef.
Canadian	Canadians have a tradition of playing hockey.

d. Adjectives referring to classes of people
Adjectives such as rich and poor can be used with the in order to refer to a group of people as a class. A plural verb must be used.
e.g. The blind attend special schools.
The poor do not own their own homes.
The rich often married for money.
In the above examples, the blind has the meaning of blind people, the poor has the meaning of poor people, and the rich has the meaning of rich people.
