谓语动词降级汇总

谓语动词指在句子中充当谓语的动词，有行为动词，系动词，情态动词和助动词等几种，其中行为动词又包括及物动词和不及物动词。 谓语动词是与非谓语动词相对应的概念.两者都是动词，但是前者是作谓语成分，后者不能作谓语成分.而谓语成分就是用来说明主语的动作或状态的，一般由动词或短语动词承担.

①、主谓分割原则

例1：to the citizens of the united states, the bald eagle,

a

america's national bird, symbolize strength and freedom.

bcd

分析：c错，应改为symbolizes。主语谓语用逗号分割开，主语the bald eagle为单数，谓语动词也应该用单数形式。

②、与后者一致原则

not…but, 强调but后面的名词，

not only…but also

③、与前者一致原则

名词+with/together with/as well as/including+复数名词，谓语用is,

中心词在前面，谓语动词应该与前面的名词保持一致

例：the athlete, together with his coach and

abc

several relatives, are traveling to the olympic games.

d

分析：d错，与谓语动词与the athlete 保持一致，改为is

④、就近原则

or, either…or, neither…nor,

单数名词+or+复数名词+are

如果把句子变为一般疑问句，也就是把be动词提到前面，那么变为is

所以注意一点： 如果是陈述句，靠后面近，用复数

如果是疑问句，靠前面近，用单数

例：the structure or behavior of many protozoans are

ab

amazingly complex for single-celled animals.

c　 d

分析：a错，应改为and。从谓语动词是复数形式判断，主语应该为复数，or连接两个名词时动词和后面的名词保持一致，behavior是用单数形式，因此只有改为并列连词and才能使主谓在数上保持一致。

⑤定语从句主语就近原则

there are five apples that are red.

apples是复数，因此从句谓语动词是复数。

例：a rocket burns propellant rapidly and most rockets

a

carry a supply that last just a few seconds.

b c　 d

分析：d错，应改为lasts。从句的逻辑主语a supply为单数，其谓语动词应为单数形式。

⑥the +形容词主谓一致

the rich are not always happier than the poor.

the rich 表示一类人，应该用复数

⑦、倒装句的主谓一致

改错题倒装句的主谓一致一般考两种情况：

a. there be 句型

there be+名词+名词，那么最近的`名词决定其形式

b. between/ among 放在句首+be+名词，名词其实是主语，所以be和名词保持一致

例：there are no known society in which left-handed people predominate.

a　bcd

分析：there be 句型由最近的名词决定其形式，society当然用单数，a错，there are 改为there is

例：between the foothills of the andes and the pacific

a　b

ocean are a dry coastal strip averaging about 30

c

miles in width.

d

分析：倒装句，are改为is

例：among the favorite attractions at the national air and

ab c

space museum in washington d.c. are the film

d

presented on the five-story-tall screen.

分析：d错，应改为films , 主语实际上是名词，应该与谓语动词保持一致。

⑧、百分比结构的主谓一致

fifty percent of + 名词

one percent of + 名词

谓语动词的形式和百分比多少没有关系，主要取决于后面的名词，比如：

one percent of my students + are

fifty percent of my time is spent on working.

这里要强调两个结构

half of =fifty percent

most of + 可数名词　+ are

most of + 不可数名词+ is

例：nearly half of the ancient meteor craters has been

a　b　c

found in central and eastern canada.

d

分析：c错，应改为have been。介词of的宾语为复数名词短语，作主语的中心词half当然表复数，相应的谓语动词应为复数形式。

例：approximately fifty percent of the package utilized

a　b

in the united states are for foods and beverages.

c d

分析：a错，应改为packages。从谓语动词用复数形式判断出主语是复数名词。注意food用复数表示不同种类的食品，beverage用复数表示不同种类的饮料，故(c)、(d)均没有错

①、主要考察时间状语

例 the metal aluminum has been first isolated early in the nineteenth century.

a　 bc　d

分析：metal, aluminum同位语，in the nineteenth century为明显表示过去时间的状语, 因此应该用过去时态，把has been改为was
