The following steps of teaching may be taken: warming up by reading aloud to the tape the text CLONING：WHERE IS IT LEADING US?；learning about appositive；building up on your word power；discovering useful words and collocations；discovering and distinguishing；closing down by talking about cloning.

Objectives

To help students revise the Appositive )

To help students discover and learn to use some useful words and collocations To help students discover and learn to use some useful structures Procedures 1. Warming up by reading aloud to the tape the text CLONING：WHERE IS IT LEADING US? 2. Learning about appositive What is an Appositive?

An appositive is a noun, noun phrase, or noun clause which follows a noun or pronoun and renames or describes the noun or pronoun. A simple appositive is an epithet like Alexander the Great. Appositives are often set off by commas.

Example: We visited the home of Harriet Beecher Stowe, the author of Uncle Tom's Cabin. (The underlined portion is the appositive.) Appositive Phrases An appositive phrase is a type of noun phrase that follows the noun or pronoun it modifies and amplifies or restricts its meaning.

Our monitor, a careful reader and outspoken critic, will examine the article before it is handed to the headmaster. [The italicized phrase is an appositive.] Appositive phrases are similar to relative clauses; to avoid wordiness, relative clauses can often be reduced to appositive phrases. 3. Building up on your word power

To build up on your word power you are to make sentences with the collocations from the text: CLONING：WHERE IS IT LEADING US? You may try to include as many uses of the Appositive as possible. 1. This is a way of learning English, the most popular language in the word. 2. People in the future will make an exact copy of themselves. 3. We may grow human beings in a laboratory in the near future. 4. They are identical in sex and appearance. 5. This mysterious thing is produced from coals. 6. The natural clones of these plants have two major uses, one for eating, one for reproduction. 7. At all the time, producing commercial quantities of concrete things is difficult. 8. We are going on with our research on the cloning of animals. 9. The determination and patience of students will be rewarded with a breakthrough in cloning. 10. Following the progress of English development we shall come to a conclusion that this world language is becoming simpler in sentence structure. 4. Discovering useful words and collocations. A collocation is two or more words that often go together. These combinations just sound "right" to native English speakers, who use them all the time.

Now you may go to page 13. Finish the four words and collocations exercises in groups of four.
