英语四级改错题考点:谓语动词
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.
一、 谓语动词的主谓一致
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.
B C D
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
A B C
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
A B
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 B C D
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
A B 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
二、谓语动词的时态
①、主要考察时间状语
例 The metal aluminum has been first isolated early in the nineteenth century.
A B C 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
②、For和since的区别
区别一:For 后面使用时间段,since 后面使用时间点
区别二:Since 只能用在现在完成时态,For 最主要用在现在完成时和一般过去时
I has been a teacher for three years.
I has been a teacher since 1996.
I was a teacher for three years. 这种表达可以,for three years表示一段时间,was 表示过去做了三年,现在不是老师了
例: Since 1921 the budget of the United States became
A B
the primary responsibility of the president.
C D
分析:A错,应改 In. since一般要求主句用完成时态,而句中谓语动词为过去式,其时间状语应与之呼应,故改Since为In。
例:Adella Prentiss Hrghes served as manager of
A B C
the Cleveland Orchestra since fifteen years.
D
分析:D错,应改为for。since引导时间状语时,主句谓语动词为一般完成时;主句谓语动词为一般过去时要用介词for;而且一段时间用for, 而不是since。
52. In general, prawns lived in shallow coastal waters or in streams.
