职称英语综合指导:语法知识—主谓语的一致
句子的各个成分之间保持在人称、性、数等方面的一致,这种关系称为一致关系。英语中的一致表现为语法一致、意义一致和毗邻一致三方面。 绝大多数谓语动词在人称和单复数上取决于主语的人称和单复数。如: The burnt child fears the fire. Things are invented when the need is great enough. 有时谓语动词的单复数取决于主语的单复数意义,而不是简单地取决于主语的单复数形式,这在集合名词作主语时尤其如此:当主语强调整体时,谓语动词用单数;当主语强调构成集合的各个成员时,谓语动词用复数。如: The basketball team consists of 20 players.(指整个球队) The basketball team are having a bath now.(指篮球队的队员) 当主语是由连词等连接的一个短语时,往往采取就近原则,即谓语动词的单复数形式取决于最靠近它的名词或代词的单复数形式和意义。如: Either the sweater or the shirts were a good buy. Either the shirts or the sweater was a good buy. ⑵可数的集体名词,如果作为一个集合概念来看,它表示单数意义,就应该遵循语法一致的原则,动词用单数形式;如果强调的是个体,它表示的就是复数意义,动词用复数形式。 如: The audience was enormous. The audience were greatly moved at the word. 常见的这些名词有:army,audience,class,club,jury,public,school,staff,government,team等。 ⑶当数学运算中的数词作主语时,谓语动词用单复数均可,但若用了plus, minus, multiplied或divide时,谓语动词多用equals. Two fours are eight. 6 multiplied by 3 equals 18. Four from five leaves one. ⑷在强调句型“It is/was…that/who…”中,强调主语时,that/who引导的从句的谓语动词的形式取决于被强调词的单复数形式或其意义。 It is precisely the people who create history. ⑸“the minority/majority of + 名词”短语作主语时,谓语动词的单复数形式取决于名词的单复数形式。如: The majority of students were on Ben‘s side. ⑹“all (any, some, a lot, lots, the rest, none, loads, the reminder和分数名词短语)of + 名词“作主语时,若名词为复数意义,谓语动词用复数形式;否则用单数形式。 Half of them are here. All the land is cultivated. Tree fourths of the surface of the earth is sea. ⑺“…form(s) / kind(s) / type(s) of + 名词”作主语时,谓语动词的单复数与form(s)等的单复数一致,此时,若名词是不可数名词,谓语动词也要用复数形式。如: This kind of book sells well. Two kinds of salt have been proved to be harmful to human body. ⑻“plenty (part, half, rest等) + 名词”作主语时,谓语动词与of后面的名词的单复数形式一致。如: Half of the guests were here. |
