4、 travel to Rome, the capital of Italy.(The appositive phrase the capital of Italy is not essential because Italy has only one capital.),An essential appositive gives necessary information about a noun and is not set off with commas.The Scarlet Letter is Hawthornes book.The book has been taken as one

Kinds of appositives,Appositives usually appear in four forms.1) Single appositive

13、 The most common type of appositives is single appositive which is a noun or a noun phrase used to identify or rename a noun in a sentence and sometimes may instead repeat a noun for the sake of clarity and emphasis:Titanic was a great ship.The ship was in Southampton.The ship sailed on April 10th,

14、1912.Its destination is New York.

15、got washed away.My school work includes physics, literature, sociology, and calculus All of my school workphysics, literature, sociology, and calculusgot washed away when my house was flooded.

16、sitive itself contains commas. Also, using dashes instead of commas serves to emphasize the appositive.,3) List appositives List appositives often go before a pronoun such as all or those or everyone. The pronoun helps to clarify the subject by drawing the items together though it is not essential t

17、o the meaning of the sentence: the opening list could serve by itself as the subject.

He himself told me that his u

21、ncle Jim is a world-famous black poet.,Occasionally, an appositive may comes before a word that it identifies or renames. When at the beginning of a sentence, the appositive is always separated by a comma from the rest of the sentence.Mexico City has many archaeological sites.These sites are interes

22、ting.Mexico City is the biggest city in the world. The biggest city in the world, Mexico City has many interesting archaeological sites.,An appositive may also be placed at the very end of a sentence.
