2、riting: Inter-sentence coherence,Clauses,There are two kinds of clauses: main clause and subordinate clause. A main clause (or a simple sentence) contains a complete thought and therefore can stand alone as a sentence. Every sentence must contain at least one main clause (MC). We waited for half an
3、hour.Nothing happened. We waited for half an hour, but nothing happened.,A subordinate clause also has a subject and a predicate, but it cannot stand alone to make sense. It needs a main clause to complete its meaning. A subordinate clause is usually introduced by subordinating conjunctions or relat

5、1. Functions and forms An adjective clause is a sentence clause that modifies a noun or a pronoun as an adjective does. Both relative pronouns (who, whom, whose, that and which) and the subordinating conjunctions (where, when and why) may be used as introducers to begin adjective clauses. Do remembe
6、r that introducers play roles in the adjective clauses and relative pronouns replace the noun that the adjective clauses modify. A noun + an adjective clause Introducer + (subject) + predicate + ,He picked up a long pipe.The pipe was covered with coins. He picked up a long pipe which was covered wit
7、h coins.(which = pipe, as a subject of the adjective clause.)He caught sight of a figure.He immediately recognized it.It was our local grocer.

9、e forgot the name of the store.At that store, her father bought her an MP4. She forgot the name of the store where her father bought her an MP4.(where = at which; which = store; as an adverbial of the clause.),2. Kinds Adjective clauses can be divided into two kinds: restrictive and nonrestrictive.
10、A restrictive adjective clause gives essential information. Without the clause, the complete meaning of the sentence would not be expressed clearly. A restrictive adjective clause should not be set off by commas.A clown is a person.He makes you laugh.A clown is a person who makes you laugh.(Without
11、the clause, “A clown is a person” doesnt make sense.)Lets go to a country.In the country, the sun always shines.Lets go to a country where the sun always shines.(Without the clause, “Lets go to a country” doesnt make the meaning of the sentence clear.),When an adjective clause is not absolutely need
12、ed in order to express the complete meaning of a sentence, it is called a nonrestrictive adjective clause. It can be omitted from a sentence without affecting the basic meaning of the sentence. It should be set off by commas. We were worried about our nearest neighbors.They were newcomers to the dis
13、trict. We were worried about our nearest neighbors, who were newcomers to the district.(As “our nearest neighbors” are clear, the sentence makes sense without the clause.)A brother was lost for a long time.People presumed him to be dead.He was really alive all the time. A long-lost brother, who was
14、presumed dead, was really alive all the time.(As “brother” has a modifier “long-lost”, it is still clear without the clause.),3. Introducers3.1.
