part tells us which thing or person the speaker is talking about.

　　T：That is to say，the function of each underlined part is the same. Each of them is used as an attribute to describe each noun. Well，are there any differences between them？

　　S1：Yes. In the first sentence，the attribute is an adjective and put before the noun；the second is a prepositional phrase put after the noun；the third and fourth sentences are full sentences put after the nouns.

　　T：You are right，what do we call the sentences put after the noun？

　　Ss：The Attributive Clause.

　　T：Quite right. In a complex sentence，the clause modifying a noun or a pronoun in the main clause is called an Attributive Clause. The noun or pronoun is called Antecedent. The word that/which introduces the clause （between the noun/pronoun and the clause） is called Relative Pronoun or Relative Adverb. The relative pronouns or adverbs do two jobs at once. They can be used as subjects，objects，attributes or adverbials；in the clause，at the same time，they join clauses together. About the use of them，we'll have particular revision after a while. Now look at the sentences on the screen.
