Betty did not go to the meeting. C. Betty might not come to the meeting. D. Betty is on the bus. The answer is B, “Betty did not go to the meeting.” The sentence is in the past tense. Man: Did Chuck call before or after the class? Woman: He called during the class. Q. Narrator: What did the woman say? A. He did not call. B. He called while the class was going on. C. He called before the class. D. He called after the class. The answer is B, “He called while the class was going on,” because while means the same as during. Passive Voice A sentence can be constructed either in the active or passive voice. In an active sentence, the subject performs the action. In a passive sentence, the subject re- ceives the action. To create a passive sentence from an active sentence, the order of the active sentence is reversed. For the Listening section, you must be able to understand active versus passive voice so you can identify who performs the ac- tion and who receives the action. 40 Part III: Detailed Review of Items Tested For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org Samples Woman: Where is David? I thought he was going to be here. Man: He was chosen to lead the committee, and it is meeting tonight. Q. Narrator: What does the man mean about David? A. He will be here soon. B. He chose the committee members. C. He has been appointed as the leader of the committee. D. He chose not to serve on the committee. The answer is C, “He has been appointed as the leader of the committee,” a pas- sive sentence. Answer choice B might be tempting, but it reverses the order of who performed the action and who received the action. Man: What did Rafael tell the officer about the accident? Woman: He said the car was struck by the truck. Q. Narrator: What does the woman mean? A. The car avoided being hit. B. The truck hit the car. C. The car hit the truck. D. The truck took evasive action. The answer is B, “The truck hit the car,” which means the same as “the car was struck by the truck.” Appositives An appositive is a reduced relative clause, which leaves a noun phrase. The noun phrase provides additional information about the noun. An appositive will often appear at the beginning of a sentence. Gary Smith, w ho is an excellent photographer, will carry the weight. relative clause Gary Smith, an excellent photographer, will carry the weight. reduced relative clause An excellent photographer, Gary Smith will carry the weight. appositive 41 Listening For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org Sample Woman: Do you know anything about the three students who are making the video display?

One person will make it successful. B. The group is made up of great photographers. C. There is no hope for the video display. D. Gary will load the equipment. The answer is A, “One person will make it successful,” because the appositive, “an excellent photographer,” refers to Gary. Modals Modal auxiliaries are generally used to indicate something that is potential or un- certain. The modals are: will, would, can, could, may, might, shall, should, and must. Sample Woman: Are you planning to go on the trip? Man: I may be able to. Q. Narrator: What does the man mean? A. He is not sure whether he will go on the trip. B. He will definitely go on the trip. C. He will definitely not go on the trip. D. He plans to go on the trip. The answer is A, “He is not sure whether he will go on the trip,” because the word may means the answer is unknown. 42 Part III: Detailed Review of Items Tested For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org Conditional Sentences A conditional sentence indicates that something will happen if another event hap- pens first. In other words, one circumstance will occur under the condition that another circumstance occurs first. A conditional sentence can be real or unreal. If it’s real, that means there is the potential for a result to occur in the future. If it’s unreal, that means a result would have occurred already if a certain event hap- pened, but in reality, the event didn’t happen. Conditional sentences each contain a clause beginning with the word if. This clause can appear as either the first or second clause in the sentence. A conditional sentence with a verb that’s one step in the past means that it’s contrary to fact, or unreal. That is, the opposite result occurred. Here is an example: If the bus hadn’t already passed by, we would’ve been on time for our meeting. OR We would’ve been on time for our meeting if the bus hadn’t already passed by. If the bus hadn’t already passed by means that the bus did pass by. This is a posi- tive result because the clause is negative (the word not — contracted here as part of hadn’t — makes it negative). Both of these sentences mean that the bus already passed by. The other clause, we would’ve been on time, is also contrary to fact. It’s a positive clause, so the idea is negative. It means we were not on time. If the bus had already passed by, there would be no people waiting. OR There would be no people waiting if the bus had already passed by. The clause If the bus had already passed by is a positive clause, so it means that the bus did not pass by. The clause there would be no people waiting is a negative clause and, therefore, carries a positive meaning. It means there are people waiting. If the man had called the ambulance, the boy would’ve survived. OR The boy would’ve survived if the man had called the ambulance. This means the man did not call the ambulance and the boy did not survive. Notice the difference, however, when the verb is in the same tense as the context. This is called a real condition because the clauses don’t have the opposite meaning. 43 Listening For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org If the bus arrives soon, we’ll be on time for our meeting. The bus still might arrive soon, and if it does, we’ll be on time for our meeting. If the man calls the ambulance, the boy can survive. The man might call the ambulance, and the boy might survive. Wish The verb wish can convey the same concept as an unreal condition. It conveys a different concept from that of hope. Just like in the unreal conditional sentences you read above, the tense of the other verb in the sentence will be one step further in the past. We wish the bus had arrived on time. This means the bus did not arrive on time. She wishes the man had called the ambulance. This means the man did not call the ambulance. Comparisons and Comparatives Comparisons indicate degrees of difference or similarity. Equal Comparisons An equal comparison indicates that the two nouns or noun phrases in a sentence are (or are not) exactly the same. This car is as old as that one. This sentence means that the age of the two cars is equal. This car is not as old as that one. This sentence means that this car is newer than the other one. In a negative equal comparison, you can substitute the word so for as without al- tering the meaning of the sentence. His job is not as difficult as mine. His job is not so difficult as mine. 44 Part III: Detailed Review of Items Tested For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org Unequal Comparisons Unequal comparisons imply that two or more entities are comparable to a greater or lesser degree. Some comparatives are formed by adding the suffix -er to the base adjective or adverb. Other comparatives are formed by adding the words more or less before the adjective or adverb. In general, it’s more common to use more to create a comparative form from an adverb. John’s grades are higher than his sister’s. adjective He studies more frequently than she does. adverb This year’s exhibit is more impressive than last year’s. adjective You can further intensify unequal comparisons by adding much or far before the comparative form. For example: This house is far more expensive than the others we’ve seen. This book is much less interesting than the one I read last month. Double Comparatives Double comparative sentences involve a comparative construction at the begin- ning of both clauses. The sooner we finish the project, the sooner we can start the next one. This sentence means the same as, “As soon as we finish the project, we can start the next one.” The more he ate, the hungrier he became. This sentence means that as he ate more, he became more hungry. Superlatives The superlative compares three or more items, one of which is superior or inferior to the others. To form a superlative, add -est to an adjective or place the words most or least before an adjective or adverb. This is the most powerful car of the three. This house is the least expensive of all. 45 Listening For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org Superlatives that involve adverbs are generally formed by using most or least rather than -est. That child behaves the most car elessly of all. adverb Negatives In the Listening section, you must pay attention to whether a sentence is positive or negative. The basic way to make a sentence negative is to add the word not to the phrase or to add the contraction n’t to the verb. Trisha is not ready to leave yet. Trisha isn’t ready to leave yet. Other negative indicators include no, never, nobody, none, and nothing. Limiting Words Another way to create a negative sentence is to use limiting words and phrases. Commonly used limiting words and phrases include hardly, seldom, never, barely, scarcely, rarely, no sooner, nowhere, not once, not often, not only, not until, only, only by, only then, only with, and under no circumstances. When these words or phrases appear at the beginning of a sentence, they signal that the normal order of a sentence will be reversed. The normal sentence order is subject + verb. In a sentence that is begun by a limiting word or phrase, an auxil- iary verb (a form of have, be, or do) appears before the subject. She had hardly finished when she collapsed with exhaustion. Hardly had she finished the race when she collapsed with exhaustion. Both of these sentences mean that she collapsed as soon as she finished the race. Never before have so many people been employed as they are now. This sentence means that more people are employed now than have been in the past. Under no circumstances will the judge reconsider her decision. This means that the judge won’t reconsider the decision under any circumstances. 46 Part III: Detailed Review of Items Tested For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org No sooner had she completed the work than she went to sleep. This sentence means that she went to sleep as soon as she completed the work. Only with great care can the surgeon reconstruct the infant’s heart. This sentence means that the surgeon can reconstruct the infant’s heart only if he or she uses great care. Not often does a hurricane of this magnitude approach the coast. This means that a hurricane of this magnitude doesn’t approach the coast often. Already and Yet The word already indicates that a sentence has a positive meaning. The word yet is used to create a negative meaning. Positive: Sandy has already finished work on her degree. Negative: Sandy hasn’t finished working on her degree yet. Another way to use yet is to place it after the have and place the rest of the verb in the infinitive. Sandy has yet to finish working on her degree. Affirmative Agreement To describe how two subjects perform or receive the same action, use affirmative agreement, in which the conjunction and is followed by a simple statement that includes either the word so or the word too. The word order of the second (sim- ple) statement differs depending on whether you use so or too. Pat is a professor, and Lynn is too. Pat is a professor, and so is Lynn. Both sentences mean that Pat and Lynn are professors. She will work for me tonight, and he will too. She will work for me tonight, and so will he. These sentences mean that both people will work for the speaker tonight. Susan drives a Lexus, and my sister does too. Susan drives a Lexus, and so does my sister. These sentences mean that Susan and the speaker’s sister both drive a Lexus. 47 Listening For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org Negative Agreement Sentences that contain negative agreement work much the same way as sentences that contain positive agreement. However, in order to indicate that the two sub- jects mentioned in this type of sentence have not done something, the words ei- ther and neither are used instead of the words so and too. I didn’t see Michelle this morning, and Joe didn’t either. I didn’t see Michelle this morning, and neither did Joe. These two sentences mean that both the speaker and Joe did not see Michelle this morning. She won’t be going to the meeting, and her colleagues won’t either. She won’t be going to the meeting, and neither will her colleagues. These sentences mean that both she and her colleagues will not attend the meeting. Tag Questions In a tag question, the speaker makes a statement but adds a brief question at the end that requests the listener to verify that the statement is true. The form is created by using the auxiliary from the main sentence (a form of be or form of have) or a form of do as the opening word of the tag question, and then repeating the noun or, more likely, replacing it with a pronoun. The auxiliary in the tag will be positive if the main sentence is negative and negative if the main sentence is positive. Bob is a good student, isn’t he? The verb comes from the is in the sentence, and the pronoun comes from the noun. Bob and Mary are good students, aren’t they? The verb comes from the are in the sentence and the pronoun comes from the nouns. There are only 28 days in February, aren’t there? Notice in a sentence beginning with there, the pseudo noun there also appears in the tag. You and I talked with the professor yesterday, didn’t we? You won’t be leaving for another hour, will you? 48 Part III: Detailed Review of Items Tested For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org Cause and Effect There are several ways to show cause and effect that you need to be able to recog- nize to score successfully on the Listening section. Because and Because Of The word because and the phrase because of show cause and effect. The cause is shown immediately after the word because or the phrase because of. Jill quit her job because she was admitted to the university. Jill quit her job because of her admission to the university. Both sentences show that Jill was admitted to the university, and the result was that she quit her job. You can also reverse the word order of either sentence: Because she was admitted to the university, Jill quit her job. Because of her admission to the university, Jill quit her job. So So means the same as because except that the result, not the cause, appears imme- diately after the word or phrase. For example: Jill was admitted to the university so she quit her job. So is sometimes followed by that in a slightly different cause and effect sentence. In the following sentence, the word that is optional. Jill quit her job so that she could attend college. Jill quit her job so she could attend college. The Reason . . . That The phrase the reason . . . that also indicates cause and effect. The phrase the rea- son is used as the subject of the sentence, as shown in the following example. The reason she quit her job was that she was admitted to the university. 49 Listening For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org . you can identify who performs the ac- tion and who receives the action. 40 Part III: Detailed Review of Items Tested For more material and information,. will go on the trip,” because the word may means the answer is unknown. 42 Part III: Detailed Review of Items Tested For more material and information,
