Question

英语have been doing反意疑问句

Answer 1

做反义疑问句的时候
首先要搞清楚助动词是哪一个
You
must
have
been
playing
tennis
at
the
time,
_?
这句话中have做助动词
引导现在完成进行时
故应该是
You
must
have
been
playing
tennis
at
the
time
,
haven't
you
?
She
must
have
a
kind
mother,_?这句话中must表示推测，而不是表“必须”，反意疑问句应该提取后面的助动词
have做的是实意动词
表示“有”的意思
其助动词应该是do
因为是第三人称单数
所以应该是She
must
have
a
kind
mother,doesn't
she?

Answer 2

答案是：用
be
动词的适当形式，比如：he
is
used
to
getting
up
early
,isn't
he
?
