　　Formulas for cash flow and the ratio of debt to equity do not apply to new small businesses in the same way as they do to established big businesses, because they are growing and are seldom in equilibrium.

　　(A Formulas for cash flow and the ratio of debt to equity do not apply to new small businesses in the same way as they do to established big businesses, because they are growing and are seldom in equilibrium.

　　(B Because they are growing and are seldom in equilibrium, formulas for cash flow and the ratio of debt to equity do not apply to new small businesses in the same way as they do to established big businesses.

　　(C Because they are growing and are seldom in equilibrium, new small businesses are not subject to the same applicability of formulas for cash flow and the ratio of debt to equity as established big businesses.

　　(D Because new small businesses are growing and are seldom in equilibrium, formulas for cash flow and the ratio of debt to equity do not apply to them in the same way as to established big businesses.

　　(E New small businesses are not subject to the applicability of formulas for cash flow and the ratio of debt to equity in the same way as established big businesses, because they are growing and are seldom in equilibrium.

　　答案：D

　　解析：In A, the they after because is ambiguous; it seems illogically to refer to Formulas because they and Formulas are each the grammatical subject of a clause and because the previous they refers to Formulas. In A and B, do not apply to... in the same way as they do to is wordy and awkward. D, the best choice, says more concisely in the same way as to. Also in B, because they refers to formulas, the introductory clause states confusedly that the formulas are growing. In C and E, subject to the [same] applicability of... is wordy, awkward, and imprecise; furthermore, are is preferable either before or after established big businesses to complete the comparison. Finally, the referent of they is not immediately clear in E.

　　State officials report that soaring rates of liability insurance have risen to force cutbacks in the operations of everything from local governments and school districts to day-care centers and recreational facilities.

　　(A rates of liability insurance have risen to force

　　(B rates of liability insurance are a force for

　　(C rates for liability insurance are forcing

　　(D rises in liability insurance rates are forcing

　　(E liability insurance rates have risen to force

　　答案：C

　　解析：In choices A and B, rates of is incorrect; when rates means "prices charged," it should be followed by for. Also in B, are a force for does not accurately convey the meaning that the soaring rates are actually forcing cutbacks in the present. In A and E, it is redundant to say that soaring rates have risen. Similarly, the word rises makes D redundant. C, the best choice, is idiomatic and concise, and it correctly uses the progressive verb form are forcing to indicate an ongoing situation.

　　Paleontologists believe that fragments of a primate jawbone unearthed in Burma and estimated at 40 to 44 million years old provide evidence of a crucial step along the evolutionary path that led to human beings.

　　(A at 40 to 44 million years old provide evidence of

　　(B as being 40 to 44 million years old provides evidence of

　　(C that it is 40 to 44 million years old provides evidence of what was

　　(D to be 40 to 44 million years old provide evidence of

　　(E as 40 to 44 million years old provides evidence of what was

　　答案：D

　　解析：D, the best choice, correctly follows estimated with to be. The other choices present structures that are not idiomatic when used in conjunction with estimated. Choices B, C, and E all mismatch the singular verb provides with its plural subject, fragments, and in choices C and E, what was is unnecessary and wordy. In choice C, the use of the verb phrase estimated that it is produces an ungrammatical sentence.

　　In his research paper, Dr. Frosh, medical director of the Payne Whitney Clinic, distinguishes mood swings, which may be violent without their being grounded in mental disease, from genuine manic-depressive psychosis.

　　(A mood swings, which may be violent without their being grounded in mental disease, from genuine manic-depressive psychosis

　　(B mood swings, perhaps violent without being grounded in mental disease, and genuine manic-depressive psychosis,

　　(C between mood swings, which may be violent without being grounded in mental disease, and genuine manic-depressive psychosis

　　(D between mood swings, perhaps violent without being grounded in mental disease, from genuine manic-depressive psychosis

　　(E genuine manic-depressive psychosis and mood swings, which may be violent without being grounded in mental disease

　　答案：C

　　解析：The best choice is C because it uses the idiomatically correct expression distinguishes between x and y and because it provides a structure in which the relative clause beginning which may be violent clearly modifies mood swings. The other choices use distinguishes in unidiomatic constructions. Additionally, their in A is intrusive and unnecessary, and the modifier of mood swings in B and D (perhaps violent is awkward and less clear than the more developed clause which may be violent.

　　Unlike a typical automobile loan, which requires a fifteen- to twenty-percent down payment, the lease-loan buyer is not required to make an initial deposit on the new vehicle.

　　(A the lease-loan buyer is not required to make

　　(B with lease-loan buying there is no requirement of

　　(C lease-loan buyers are not required to make

　　(D for the lease-loan buyer there is no requirement of

　　(E a lease-loan does not require the buyer to make

　　答案：E

　　解析：Choice E, the best answer, correctly uses a parallel construction to draw a logical comparison: Unlike a typical automobile loan,... a lease-loan.... Choice A illogically compares an automobile loan, an inanimate thing, with a lease-loan buyer, a person. In choice C, buyers makes the comparison inconsistent in number as well as illogical. Choices B and D are syntactically and logically flawed because each attempts to compare the noun loan and a prepositional phrase: with lease-loan buying in B and/or the lease-loan buyer in D. Choices B and D are also imprecise and awkward. Finally, choice E is the only option that supplies an active verb form, does not require, to parallel requires.

　　Native American burial sites dating back 5,000 years indicate that the residents of Maine at that time were part of a widespread culture of Algonquian-speaking people.

　　(A were part of a widespread culture of Algonquian-speaking people

　　(B had been part of a widespread culture of people who were Algonquian-speaking

　　(C were people who were part of a widespread culture that was Algonquian-speaking

　　(D had been people who were part of a widespread culture that was Algonquian-speaking

　　(E were a people which had been part of a widespread, Algonquian-speaking culture

　　答案：A

　　解析：Choice A is best because it correctly uses the simple past tense, the residents... at that time were, and

　　because it is the most concise. In B and D, the replacement of were with the past perfect had been needlessly changes the original meaning by suggesting that the Native Americans had previously ceased to be part of the widespread culture. All of the choices but A are wordy, and in C, D, and E the word people redundantly describes the residents rather than the larger group to which the residents belonged. These choices are also imprecise because they state that the culture, rather than people, spoke the Algonquian language. Choice E displays inconsistent tenses and an error of pronoun reference, people which.

　　Each of Hemingway's wives--Hadley Richardson. Pauline Pfeiffer. Martha Gelhom. and Mary Welsh –were strong and interesting women, very different from the often pallid women who populate his novels.

　　(A Each of Hemingway's wives--Hadley Richardson, Pauline Pfeiffer, Martha Gelhom, and Mary Welsh--were strong and interesting women,

　　(B Hadley Richardson, Pauline Pfeiffer, Martha Gelhorn, and Mary Welsh--each of them Hemingway's wives--were strong and, interesting women,

　　(C Hemingway's wives--Hadley Richardson, Pauline Pfeiffer, Martha Gelhom, and Mary Welsh--were all strong and interesting women,

　　(D Strong and interesting women—Hadley Richardson, Pauline Pfeiffer, Martha Gelhom, and Mary Welsh--each a wife of Hemingway, was

　　(E Strong and interesting women—Hadley Richardson, Pauline Pfeiffer, Martha Gelhom, and Mary Welsh--every one of Hemingway's wives were

　　答案：C

　　解析：Each choice but C contains errors of agreement. In both A and E, the singular subject (each in A, every one in E does not agree with the plural verb were, while in D, the plural subject women is mismatched with the singular verb was. In B, the subject and verb agree, but the descriptive phrase placed between them creates an illogical statement because each cannot be wives; each can be one of the wives, or a wife. The pronoun constructions in A, B, D, and E are wordy; also, B, D, and E are very awkwardly structured and do not convey the point about Hemingway's wives clearly. Choice C correctly links wives with were, eliminates the unnecessary pronouns, and provides a clearer structure.

　　In addition to having more protein -than wheat does, the protein in rice is higher quality than that in wheat, with more of the amino acids essential to the human diet.

　　(A the protein in rice is higher quality than that in

　　(B rice has protein of higher quality than that in

　　(C the protein in rice is higher in quality than it is in

　　(D rice protein is higher in quality than it is in

　　(E rice has a protein higher in quality than

　　答案：B

　　解析：In this sentence, the initial clause modifies the nearest noun, identifying it as the thing being compared with wheat. By making protein the noun modified, choices A, C, and D illogically compare wheat with protein and claim that the protein in rice has more protein than wheat does. In C and D, the comparative structure higher in quality than it is in wheat absurdly suggests that rice protein contains wheat. B, the best choice, logically compares wheat to rice by placing the noun rice immediately after the initial clause. B also uses that to refer to protein in making the comparison between the proteins of rice and wheat. Choice E needs either that in or does after wheat to make a complete and logical comparison.

　　An array of tax incentives has led to a boom in the construction of new office buildings; so abundant has capital been for commercial real estate that investors regularly scour the country for areas in which to build.

　　(A so abundant has capital been for commercial real estate that

　　(B capital has been so abundant for commercial real estate, so that

　　(C the abundance of capital for commercial real estate has been such,

　　(D such has the abundance of capital been for commercial real estate that

　　(E such has been an abundance of capital for commercial real estate,

　　答案：A

　　解析：Choice A is best. The construction so abundant has capital been... that correctly and clearly expresses the relationship between the abundance and the investors' response. In choice B, the repetition of so is illogical and unidiomatic. Choices C, D, and E alter somewhat the intended meaning of the sentence; because of its position in these statements, such functions to mean "of a kind" rather than to intensify abundant. Choice D awkwardly separates has and been, and the omission of that from C and E makes those choices ungrammatical.

　　The original building and loan associations were organized as limited life funds, whose members made monthly payments on their share subscriptions, then taking turns drawing on the funds for home mortgages.

　　(A subscriptions, then taking turns drawing

　　(B subscriptions, and then taking turns drawing

　　(C subscriptions and then took turns drawing

　　(D subscriptions and then took turns, they drew

　　(E subscriptions and then drew, taking turns

　　答案：C

　　解析：The sentence speaks of a sequence of actions in the past: shareholders made their monthly payments and subsequently took turns drawing on the funds. Choice C, the best answer, uses parallel past-tense verb forms to express this sequence. Choices A and B violate parallelism by using taking where took is required. The wording in D results in a run-on sentence and does not specify what the members took turns doing. Similarly, E does not specify what the members drew, and taking turns produces nonsense when combined with the rest of the sentence.
