主谓一致需要视具体情况而定的情形 1. 基数词单纯表示数字作主语时，谓语动词通常用单数，但当基数词表示的不是数字而是数量时，谓语动词可用复数。由此可推断出，分数或百分数作主语时，其谓语动词的形式取决于分数或百分数所指的具体含义。 例题：The university estimates that living expenses for international students ________ around $8,450 a year, which ________ a burden for some of them. A. are；is B. are；are C. is；are D. is；is 2. half of, the rest of, most of, all of及百分数或分数+of 等后接名词，作主语时,谓语动词形式根据of后的名词而定。 例题：As a result of the serious flood, two-thirds of the buildings in the area ______. A. need repairing B. needs to repair C. needs repairing D. need to repair 【答案与解析】A 本题考查主谓一致和非谓语动词。 分数、百分数修饰名词, 谓语动词的单复数取决于名词, 此处two-thirds修饰buildings, 故谓语动词取决于名词复数buildings , 排除B、C两项, need doing=need to be done意为 “需要被做”。 3. 若主语是由“a kind/type of +名词”构成时,谓语动词通常用单数形式；但在“these/those kind/type of+复数名词”之后，谓语动词则常用复数形式。 例如： There is a kind of rough wall surface, which is said to be sound-absorbing. 有一种墙面是麻的，据说可以吸音。 I told him you work with me, that these kind of situations are your specialty.我告诉他你是我同事，这种情况是你的专长。 注意：a series of 表示“一系列”，后面跟复数名词。但其动词谓语用单数还是用复数，取决于本短语表示的是一系列“同一种类”的事物还是“不同种类”的事物。前者用单数谓语；后者用复数谓语。 例题： A series of pre-recorded tapes ____ prepared for language laboratory use. A. has been B. have been C. are D. must have 4. what引导的主语从句,谓语动词可视表语而定：表语是单数名词时，动词用单数，反之则用复数。 例如：What they want to get are a number of good books. 他们想得到的是大量的好书。 What they want to get is the number of good books. 他们想要得到的是好书的数量。 5. one of+复数名词+ 定语从句的结构中,定语从句的谓语动词要用复数；而在the only one of +复数名词+定语从句的结构中，定语从句的谓语动词要用单数。 例如：He is one of the students who get there on time. 他是准时到达那里的学生之一. Tom is the only one of the students who was late this morning. 在这些学生中汤姆是今天早上唯一迟到的人。 【小试牛刀】 1．At the end of the historic area, Wilmington displayed its____ as a working port city: large ware-houses and a few other dated office buildings.
