主谓一致是什么?
主谓一致就是句子的谓语动词形式在人称和数上必须和句子的主语保持一致,叫主谓一致。
这种关系一般要遵循三个原则:语法一致的原则、意义一致的原则和就近一致的原则。
语法一致
谓语和主语通常从语法形式上取得一致,主语为单数形式,谓语动词也用单数形式;主语为复数形式,谓语动词也为复数形式。如:
The
boy
is
clever
enough
to
study
math
well.
Everybody
in
my
class
tries
to
do
well
in
English.
They
are
excellent
players
and
won
the
game.
语法一致(仅用单数)
不可数名词或可数名词单数作主语,谓语动词用单数形式。如:
Water

the
trees.
语法一致(仅用单数)

two
thousand.
语法一致(仅用单数)
如果句子的主语是单数,尽管后面有with,together
with,as
well
as,like,but,except等引起的短语,谓语动词仍然用单数形式。如:
My
mother
with
her
students
often
has
a

答案:
1.
【答案】A
【解析】
试题分析:—
我昨天下午五点给你打电话了,但是没人接。—
对不起,那时我正陪着妈妈买东西呢。通过以上分析可知,应该用过去进行时;本句I是主语,with
my
parents是介词短语做定语,不是主语,所以后面用was。故选A。
考点:考查时态和主谓一致的用法。
2.
【答案】B
【解析】
【详解】
句意:我每个月零花钱中的50%花费在了娱乐上。am用于主语为第一人称I的时候;is用于主语是单数时;are用于主语是复数时;be是am,
is和are的原形。该句的主语为Fifty
percent
of
my
monthly
pocket
money,分数或者百分数+of+名词作主语时,谓语动词的单复数形式应与名词形式一致,这里money是不可数名词,谓语动词应用单数,故应选B。
3.【答案】B
【解析】
试题分析:句意:---你的老师来自哪?---澳大利亚。此题考查系动词,因为your
teacher是第三人称单数,故用is。根据句意,应选B。
考点:考查主谓一致。
4.
【答案】B
【解析】
试题分析:句意:你的妹妹和我的妹妹都不知道这个好消息,让我们告诉他们。根据neither...nor...表示两者都不,谓语动词采用就近原则。根据题意可知故选B
考点:考查主谓一致
5.
【答案】D
【详解】
试题分析:句意为:---你们班有多少女生?---女生的人数超过20人。a
number
of指的是“许多的,大量的”,接名词时,谓语动词常用非第三人称单数形式;the
number
of指的是“……的数量”,谓语动词常用第三人称单数形式。根据语境可知,这里指的是“数量”,故应选D。
6.
【答案】B
【解析】
试题分析:句意:-你为什么这么匆忙,迈克?-有在十分钟后有一场NBA篮球比赛。根据in
ten
minutes可知该用一般将来时。根据句意这里是一个There
be句型。所以选B。
考点:考查There
be句型的一般将来时。
7.
【答案】D
【解析】
试题分析:句意:据说世界上的三分之二的水被污染了。在英语中分子用基数词表达,分母用序数词表达如果分子大于1,分母变复数。三分之二,two
thirds。分数,作主语时,根据其后接的词而定,如果为不可数名词,则相当于单数,如果其后接的为可数名词复数形式,则相当于复数,根据句意及结构,故选D
考点:考查分数的用法。
8.
【答案】B
【解析】句意:安迪和他的父母去了香港,他们将买一些东西。Andy是句子的主语,with
his
parents作状语,根据主谓一致的原则,首先排除A,C;have/has
gone
to表示某人去了某地,现在还没有回来,have/has
been
to表示某人去过某地,现已回来。根据by
them判断,第二个句子是被动语态的句子,故答案为B。
9.
【答案】A
【解析】
试题分析:句意:现在无论是苏西还是我都害怕公开演讲。Neither

nor既不……也不,当连接并列主语时,要遵循就近原则,所以选A。
考点:考查主谓一致。
10.
【答案】B
【解析】
试题分析:句意:---你听说过学校附近的车祸吗?---是的,幸运的是,没有一个人受伤。hurt伤害,no
one与hurt是被动关系,no
one动词用单数,
故选B
.
考点:考查被动语态和主语一致
11.
【答案】C
【解析】
试题分析:句意:看!有一座新桥。是上个月修建的。前句描述的是现在的状态,用一般现在时态,be用is;后句描述的是上个月发生的过去动作,用一般过去时态。主语it(指bridge)是谓语动词build的承受者,用被动语态。故选C。
考点:考查动词的时态、语态辨析。
12.
【答案】A
【解析】
句意:这些听力材料,连同它的光盘卖得很好。根据句意,东西卖的好,表示现在的一种状态,故用一般现在时。并且当sell后接副词时,其主动形式表示被动含义。together?with?连接几个主语时,谓语动词要与最前面的主语保持一致,?即与?listening?material?保持一致,所以sell用单数形式;故答案选A。
?
点睛:表示事物性质或特点的,用主动形式表示被动语态。此处表示这个听力材料卖得好,sell可用作及物动词和不及物动词,其主语一般是指人,但是在表示某物卖得不错时,要用主动语态表示被动。together?with?连接几个主语时,谓语动词要与最前面的主语保持一致,即采用就远原则,本句是与listening
material保持一致,所以谓语动词用单数形式。故答案选A。
13.
【答案】B
【解析】
句意:伊芙或赫伯已经被路西的父母邀请了。
Either
...
or...或者……或者,连接两个主语时,用就近原则,already是现在完成时的标志词,结合句意,故选B
14.
【答案】D
【解析】
句意:妹妹和我功课都很好。妈妈以我们为骄傲。not
...
but
...不是……而是……;neither
...
nor
...既不……也不……;either
...
or
...
或者……或者……;both...
and...
两者都。根据句意My
mother
is
very
proud
of
us可知,妹妹和我功课都很好,故选D。
15.
【答案】B
【解析】
句意:在我们城市志愿者的数量为2000.他们中的百分之六十是教师和学生。根据句意,结合语法知识the
number
of,……的数目,做主语时谓语动词使用单数形式,而percent做主语时,谓语动词的单复数需要依据of后面的单词。故答案为B.
16.
【答案】C
【解析】
句意:看!有那么多人站在这里,你知道发生什么事了吗?is是,be动词的形式,主语为单数;are是,be动词的形式,主语为复数;standing站,现在分词,表示动作正在进行。这句话考查的是there
be句型,意思是“有”,主语为so
many
people,是复数的,故排除A。句中已经有了谓语动词are,因此第二个空应填非谓语动词,are
standing是现在进行时,是谓语动词的形式,故不合适,选C,standing是现在分词作伴随状语。
17.
【答案】B
【解析】
