Subject and predicate 2Hard-to-find subjects Writing: Correcting: Sentence fragments Rewriting: Sentence combining strategies Subject and predicate A sentence is a group of words that expresses a complete thought. Every sentence has two basic parts, a subject and a predicate. The subject is the naming part of the sentence, representing the person, place, or thing that performs the action of the verb or expressing the condition or state of the verb. Subjects are nouns and other forms that can function as nouns, such as pronouns, clauses, infinitives and gerunds. A subject usually comes first in a sentence. It is the topic about which the speaker or writer is speaking or writing. For example, 1) My grandfather bought the car many years ago. 2) The car was bought many years ago by my grandfather. Fill in the blanks: 1) My grandfather bought the car many years ago. 2) The car was bought many years ago by my grandfather. In my garage, there is an old car. _. It is a Cadillac, a very classical luxury car, manufactured in 1966. The car has 65.000 original miles on it, but sitting in a damp garage for most of its life didnt do many favors for it. Fill in the blanks: 1) My grandfather bought the car many years ago. 2) The car was bought many years ago by my grandfather. In my garage, there is an old car. It is my grandfathers gift for my grandmother. _. In order to buy this car, my grandfather had been saving his money for quite a few years. He worked as a truck driver for a local grocery chain, and supported a big family on his salary. Needless to say, money was pretty hard to come by that time. According to my grandmother, at the end of the day he would come home and empty his space change into a jar beside the bed. When the jar was full, he would take it to the band. Predicates are verbs. A predicate is the doing or being part of the sentence, expressing the action or state of being of the subject. The predicate, often coming after the subject, is the semantic and grammatical center of a sentence. I bought a house for my parents. Some of the buried workers are still alive. The babies grew nervous from the loud noise. A verb is often made up of more than one word. The verb that expresses the action or state of being of the subject is called main verb. The word that accompany the main verb is called an auxiliary/ helping verb, which helps the main verb express mood or time by forming various tenses. George must be playing basketball with them now. The thief has been caught in a deserted building. Auxiliary /helping verbs can not be used alone in a sentence. It must go together with main verbs. Correct the following sentences： Tomorrow will surely better. Our campus will more and more beautiful. When you opened the window, the room would immediately bright. Verb can be classified into two: action verbs and linking verbs. An action verb expresses an action, such as do, act, make, walk, take, break, react, write, see, say, buy, build and so on. A linking verb links/joins the subject of a sentence (often a noun or a pronoun) with a noun, a pronoun, or an adjective that identifies or describes the subject. It does not show action, but express the existence or state of being of the subject. A noun, a pronoun or an adjective that follows a linking verb is called a predictive, which points back to the subject to rename it, to identify it or to describe it further. There are eleven linking verbs which are most frequently used. We can briefly put them into three groups. expressing judgment or change: be, get, turn, prove indicating five senses of humans: look, feel, smell, taste, sound some others, “GRABS”: grow, remain, appear, become, seem Examples： For years her grandfather was one of the town leaders. My coat seemed too large. Pineapple sometimes tastes better with salt. Most students feel disappointed with the result. The time of his birth remains a mystery to us. Locating the Subject and Verb Forest fires are often caused by broken glass. By then, however, in many places the grass had already taken root. A woman you know well will rush towards you. Each of the students requested more homework. The leader of the party was examining the soil near the entrance to the cave. It suddenly occurred to one of the workers to open up the box. Then he sits and barks until someone lets him out. To their surprise, the precious parcel was full of stones and sand! Tony saw me and came and sat at the same table. If you park your car in the wrong place, a traffic policeman will soon find it. 2. Hard-to-find subjects 1. There/Here be Most frequently, a subject comes first in a sentence and usually goes before a predicate. However, sentences can be built so that the predicate comes before the subject. One way to make such a sentence is to begin a sentence with there or here. Notice the placement of subjects in the following examples. The subjects are underlined once and the predicates twice. Here is your ticket. Here are the children. There are lots of pine trees in the park. There will be an international exhibition next year. In the sentence patterns “There/Here be ”, the predicate “be” can also be replaced by an action verb such as come, live, remain, stand, lie, appear, exist, seem, remain and so on. Here comes the bus. There goes the little boy. There lived six bland men in a small Indian village. There existed a great tribe centuries ago. 2. Imperative sentences An imperative sentence gives an order/ command, or makes a request: The subject you is understood. It doesnt need to be stated. Obviously, the word you means the person (subject) being ordered or commanded. Shut up! (You) shut up! Show me your passport. (You) show me your passport. Close the door behind you. (You) close the door behind you. 3. Interrogative sentences An interrogative sentence asks a question, usually ending with a question mark. When you build questions, you place a helping/ auxiliary verb before the subject and leave a main verb behind. Have you applied for the job? Did Jim finish his project and hand it in early? When did the witness report the accident? 4. Inverted Sentences An inverted Sentence is a sentence built in the way that the predicate comes before the subject. It serves to add emphasis to the subject. An inverted sentence usually begins with a prepositional phrase. Along country roads grow many flowers. On the floor is your homework assignment. Down the steps of the palace walks journalist. Locating the Subject and Verb Do not come in unless asked. In front of the tower flews a stream. Many years ago there lived an old man in the wooden house. Be careful when crossing the street. Is this your cell phone number? Away went the crowed one by one. Never be late again next time. To each of the neighbors came a reward. At the top of the lemon tree there is a sparrows nest. Right from the start there was trouble with the Hubble telescope. “Did you have a good meal?” he asked. What did she want to repair? 3. Sentence Fragment Every sentence must have a subject and a verb and must express a complete thought. A word group that lacks a subject or a verb and that does not express a complete thought is a sentence fragment. 1. Lack of a subject A subject is like a head for a human that you cannot go without it. Lack of a subject is one of the most common errors in writing. Two solutions are available: 1) adding a subject to the fragment to make it a complete sentence; 2) combining the fragment with another sentence if the two share a subject. I looked for a place to turn around. But only found a narrow road. I looked for a place to turn around. But I only found a narrow road. I looked for a place to turn around but only found a narrow road. I looked for a place to turn around but only to find a narrow road. 2. Lack of a complete verb A predicate verb is most necessary for a sentence. The error of lacking a complete verb can be corrected by: 1) adding a complete verb or a helping verb to make the sentence complete; 2) combining the fragment with another sentence. I was fully awake now. I wondering what had happened to me. I was fully awake now. I was wondering what had happened to me. I was fully awake now, wondering what had happened to me. Fully awake now, I was wondering what had happened to me. 3. Lack of both a subject and a verb. A group of words without a subject and a verb is only a fragment. The error can be corrected by combining it with another sentence. The Titanic was completed in 1912. The most luxurious ship of its day. The Titanic, the most luxurious ship of its day, was completed in 1912. Completed in 1912, the Titanic was the most luxurious ship of its day. 4. Lack of a main clause A main clausesometimes called an independent clauseis a clause that can stand by itself and still make sense. You must have at least one main clause in every sentence. A main clause is the essential component. Without a main clause, a group of words is a fragment. Two solutions are available: 1) combining the fragment that is a subordinate clause with a main clause; 2) rewriting the fragment as a complete sentence, eliminating the subordinating conjunction or the relative pronoun and adding words necessary to make a complete thought.
