二、主谓一致
英语中,主语的单复数形式决定着谓语动词所采取的形式,这被称作主谓一致。
1.语法一致原则
主语和谓语通常是在语法形式上取得一致,即主语是单数形式时,谓语动词也采用单数形式;主语是复数形式时,谓语动词也采用复数形式。
①当and或both...and...连接名词作主语时,谓语动词用复数形式。
Tom
and
Mike
are
good
friends.
Both
Lucy
and
Lily
are
students.
②不定代词
either,
neither,
each
one,
the
other,
another,anybody,
anyone,
anything,
someone,
somebody,
something,
everyone,everybody,
everything.,
nobody,none,
nothing等作主语时,谓语动词用单数形式。
Is
there
anything
wrong
with
your
bike?
Everyone
is
ready
for
the
sports
meeting.
③由each,each...
and
each…,
every…
and
every…作主语时谓语动词用单数形式。each作主语的同位语时,谓语动词用复数。
Each
of
us
has
got
a
book.
Each
boy
and
each
girl
was
given
a
new
book.
The
children
each
have
an
apple.
④主语后接有with,
along
with,
together
with,
as
well
as,
like,
including,
besides,except,but等词或短语时,谓语动词的单复数形式由主语的单复数形式决定。
Mr.
Green
with
his
wife
and
two
daughters
is
coming
to
Beijing.
⑤“
a
number
of+名词复数”作主语时,谓语动词用复数形式;the
number
of+名词复数“作主语时,谓语动词用单数形式。
A
number
of
trees
are
cut
down.
The
number
of
students
in
our
class
is
32.
⑥“
a
lot
of
(
lots
of,
plenty
of,
a
pile
of,
most
of)+名词”和“分数或百分数+of+名词”等作主语时,谓语动词的单复数形式取决于名词,如果是不可数名词,则谓语动词用单数形式;如果是可数名词复数,则谓语动词用复数形式。
Lots
of
people
have
been
there.
⑦由“a
pair/
kind
+复数名词”作主语时,谓语动词用单数形式;“pairs/kinds+复数名词”作主语时,谓语动词用复数形式。
A
pair
of
shoes
is
under
the
chair.
⑧由两部分构成的表示物体的名词(如trousers,shorts,
shoes,
gloves...)作主语时,谓语动词用复数形式。
My
shoes
were
won
out.
⑨不定式或V-ing形式作主语时,谓语动词用单数形式。
Mending
the
car
is
his
job.
To
learn
English
well
isn’t
very
easy.
2.意义一致原则
意义一致又叫概念一致,即谓语动词用单数形式还是复数形式要看主语所表达的概念。
①由and连接的两个名词作主语,如果是指同一概念(即and后面无冠词),则谓语动词用单数形式。
The
teacher
and
writer
is
coming
to
give
us
a
report
next
week.
②表示金钱、价格、时间、长度等复数名词、短语作主语时一般被看作一个整体,谓语动词常用单数形式。
Three
years
is
a
long
time.
③集体名词(如family,team,crowd,company,class,group...)如果表示整体概念,则谓语动词用单数形式;表示集体中的成员,则谓语动词用复数形式。
The
crowd
are
fighting
for
their
lives.
④people,
police,cattle等集合名词作主语时,谓语动词复数形式。
The
police
are
helping
a
girl
find
her
mother.
⑤one
and
a
half的后面要接复数名词,作主语时谓语动词复数形式;one+单数名词+and+a
half作主语时谓语动词用单数形式。
One
and
a
half
cakes
are
a
good
meal
for
the
monkey
One
cake
and
a
half
is
a
good
meal
for
the
monkey
⑥“the+姓氏名词复数”表示“…一家”或“……夫妇”,当它在句中作主语时,谓语动词应用复数形式。
The
Blacks
enjoy
working
in
China.
⑦某些名词以s结尾如maths,
politics,
physics,
news等,谓语动词应用单数。
Physics
is
a
very
interesting
subject.
3.就近原则
就近原则是指谓语动词的单复数形式取决于靠近它的用作主语的名词。
①由either..or.,
neither.nor.,
not
only…but(also)…,not...but...或or连接两个并列主语时,谓语动词与较近的主语在数上保持一致。
Not
only
my
parents
but
also
I
am
looking
to
meeting
my
uncle.
②There
be...和
Here
be...这两个句式中的be动词常与最近的主语在数上保持一致。
There
is
a
table
and
two
chairs
in
Tom's
room.
There
are
two
chairs
and
a
table
in
Tom's
room.

(there)
in
