Question

疑问句中谓语动词什么时候用do,does did ，什么时候用is are,was ,were

Answer 1

1.
do,
does,did
要根据时态。
do,
does
用于一般现在时，当一般现在时的句子中谓语动词为原形的话，改为疑问加do
eg.
They
like
English.
-------
Do
they
like
English?
Lucy
and
Lily
come
from
the
UK.
-------
Do
Lucy
and
Lily
come
from
the
UK
?
而当一般现在时的句子中谓语动词后加s/es,改为疑问要在句首加does，并且将谓语动词改为原形
eg.
he
likes
english.
-------does
he
like
english?
he
teaches
us
english.
-------does
he
teach
us
english?
did
用于过去时的一般疑问句，同样看谓语动词是否用了过去式，改时放在句首，谓语动词同样改为原形
eg.
they
wanted
to
go
home.
--------
did
they
want
to
go
home?
he
liked
to
stay
at
home
before.
-------did
he
like
to
stay
at
home
before?
特别注意的是要仔细掌握不规则的动词过去式，尤其是跟原形一样的，举两例
eg.
he
read
the
novel
last
night.
--------
did
he
read
the
novel
last
night?
the
book
cost
him
30
yuan.
--------
did
the
book
cost
them
30
yuan.
2.is
are,was
,were
简单的就是看句中有无这些词，有就提前放句首，后面的不变。具体而言
is
are
在一般现在时中
eg.
he
is
a
student.
--------
is
he
a
student?
they
are
from
Class
9
--------Are
they
from
class
9?
