Lecture 3Subject-verb Concord (II)This lecture deals with problems of concord with a coordinate construction, a quantitative expression, or a nominal clause as subject.3.1 Problems of concord with a coordinate subjectThe following rules are to be observed in the case of a coordinate subject.1) Coordination with and or bothandCoordination by and or bothand is usually treated as plural when it refers to two or more than two persons / things, but it is treated as singular when it refers to only one person or thing. Compare:Both Pauline and Bob have gone fishing on Miramar Lake.Rain, hail and wind have caused an estimated $ 22,000,000 damage to crops and livestock.The secretary and treasurer was absent from the meeting.Ham and eggs is a good breakfast.2) Coordination with or / eitheror, nor / neithernor, not onlybut also Here the problem of concord is generally dealt with according to the principle of proximity. But in informal style, items coordinated by neithernor or not only but also can sometimes be regarded as plural, eg:My sisters or my brother is likely to be at home. Either my father or my brothers are coming.Neither the players nor the coach was overconfident.Not only the switches but also the old wiring has been changed.3.2 Problems of concord with expressions of quantity as subject Quantitative expressions fall into two categories: definite and indefinite.1) Concord with expression of definite quantity as subjectWhen a definite quantity is regarded as a single unit, the verb takes the singular form and when used in the sense of the individuals that constitute the quantity, the verb takes the plural form. Compare:He thought that 65 dollars was not too much to ask. There were 6 silver dollars in each of the stockings.If the subject is a fraction / percentage + of-phrase, the form of the verb is determined by the noun in the of-phrase. A plural noun in the of-phrase requires a plural verb; a singular or a mass noun in the of-phrase is to be followed by a singular verb, eg:Over 60 % of the city was destroyed in the war.Two thirds of the swampland has been reclaimed for farming.Nearly 50 % of the doctors are women.If the subject is an expression of A plus / and B or A multiplied by B, the verb can either take the singular or the plural form. If, on the other hand, the subject is one of “A minus B or A divided by B, the verb can only be singular, eg:Seven plus / and five (7 + 5) makes / make twelve.Forty minus fifteen (40 -15) leaves twenty-five.Five times eight (5 x 8) is / are forty.Forty divided by eight (40 -7 8) is five.If the subject is a noun phrase composed of one in / out of + plural noun, the verb takes the singular form in formal style, but in informal style it can be plural, eg:One in ten students has / have failed the exam.One out of twenty was / were badly damaged.2) Concord with expression of indefinite quantity as subject When the subject is a noun phrase composed of all of ., some of ., none of ., half of ., most of ., etc, the number of the verb is determined by the noun in the of-phrase. This is also true of lots of, heaps of, loads of, scads of, plenty of + noun, eg :All of the cargo was lost.All of the crew were saved.Lots of food is going to waste. Lots of people are waiting outside.When the subject is a noun preceded by a portion of, a series of, a pile of, a panel of, the verb invariably fakes the singular .form, whatever the forms of the noun. Likewise, when the subject is a noun, singular or plural, preceded by a kind / sort / type of or by this kind / sort / type of, .the verb takes the singular form. If kind / sort / type of is preceded by these / those and followed by a plural noun, the verb should be plural, eg:A substantial portion of the reports is missing.A series of accidents has been reported.This kind of man annoys me.That type of men is dangerous.These sort of machines are up to date.If the subject is a noun phrase composed of many a -;/- noun or more than one + noun, this kind of noun phrase, though notionally plural, is treated as singular:Many a man has done his duty.More than one game was lost.If the subject is a plural noun preceded by an average of / a majority of, the verb form is determined by the notion of the noun phrase: if the noun head is the word average / majority, the verb should be singular; if the head is the plural noun, the verb should be plural. Compare:An average of 25 applications a month is not unusual. An average of 25 persons apply each month.3.3 Other problems of subject-verb concordThere are other problems of subject-verb concord that are worth mentioning.1) Problems of concord with a nominal clause as subjectWhen the subject is a nominal clause introduced by what, who: which, how, why, whether, etc, the verb usually takes the singular form. But when two or more such clauses are coordinated by and or both. . and, a plural verb is required, eg:What caused the accident is a complete mystery.What caused the accident and who was responsible for it remain a mystery to us.In SVC constructions with a what- clause as subject, the verb usually takes the singular form. But when the subject complement is plural, or when the what- clause is plural in meaning, the verb of the main clause can be plural, eg:What was real to him were the details of his life.What are often regarded as poisonous fungi are sometimes safely edible.2) Subject-verb concord with a non-finite clause as subject When the subject is a non-finite clause, the verb of the main clause usually takes the singular form. But when two or more such clauses are coordinated by and, the verb of the main clause takes the singular form when the subject refers to one thing, and the plural form when the subject refers to separate things, eg:To climb mountains requires courage. Playing tennis is very good exercise.Compare:Reading Ibsen and solving a quadratic equation are entirely different assignments.3) Subject-verb concord in relative clausesIn the construction of one of + plural noun + relative clause, the principle of grammatical concord is generally observed. Sometimes, especially in British English, in order to lay emphasis on one, the verb can also take the singular form. When one is preceded by the or the only the verb can only be singular. Compare: Joan is one-of those people who go out of their way to be helpful.Jasper White is one of those rare people who believes in ancient myths.Keves is the only one of the players who has learned all the rules.4) Subject-verb concord in cleft-sentencesIn cleft-sentences, subject-verb concord in that- / who- clause is generally determined by the number of the focal element functioning as subject in the clause. There is one point that should be noted: when the focal element is I, the verb TO BE in the following who- / that-clause usually agrees with I in both person and number; if, on the other hand, the focal element is me instead of I, the verb TO BE in the following who- / that- clause sho
