网上有详解
我看的:一、变一般疑问句
1、移:把be动词、情态动词、助动词移到主语之前,加问号即可。如:
He
is
a
student----Is
he
a
student?(含be动词)
I
can
speak
English----Can
you
speak
English?(含情态动词)
I
have
learnt
English
for
5
years.---Have
you
learnt
English
for
5
years?(含助动词)
2、加:加助动词。看原句的时态判断加哪个助动词。如:
I
like
it.---Do
you
like
it?(一般现在时加Do
)
He
likes
dogs.---Does
he
like
dogs?(一般现在时单三加Does)
She
went
to
the
park
yesterday.---Did
she
go
to
the
park
yesterday?(一般过去时加Did,然后要
把原来的过去式went变为原形go)
二、特殊疑问句
一变:把原来的陈述句变成一般疑问句。
二加:加特殊疑问词(what,where,how,等)
三去:去掉划线部分。
There
is
(a
book)
on
the
desk.----what
is
on
the
desk?
疑问词怎么选要看就什么提问,就时间提问用when
,what
time,就地点提问用where,就物提问用what,等等。
