但是提醒几点：
need
有实意动词，情态动词，实意时注意要用do,does反问
must的否定反问一般用needn't不是mustn't
have要注意区分助动词，实意动词（这个不是情态动词哈）

careless
为形容词
carefully为副词
care理解为动词
而句中come为动词，前面有to
应遵循两个动词之间加to，所以只能选动词care
也可以这样理解
care
+v（动词）意为愿意，喜欢，要
eg:Would
you
care
to
go
to
dinner?
你愿意出去吃饭吗？
整句话的意思为
如果你愿意,你任何时候来

You
can
play
piano,
can't
you?
He
can't
go
to
school
today,
can
he?
但注意下列情况:
1
当陈述部分带有情态动词ought
to时，反意疑问部分在英式英语中用ought
to
形式，在美式英语中用should形式。例如：
You
ought
to
see
the
new
picture,shouldn't
you?
Teachers
ought
to
be
honoured,oughtn't
they?
2
当陈述部分带有情态动词used
to时，反意疑问部分可以用used
to形式，也可以用did形式。例如：
She
used
to
live
abroad,usedn't
she?
There
used
to
be
a
newsstand
in
the
corner
of
the
street,didn't
there?
3
当陈述部分带有情态动词must时，反意疑问部分需视must的含义而定。
a.当must表示“命令或强制”时，反意疑问部分用mustn't。例如：
You
must
do
it
by
yourself,mustn't
you?
b.当must表示“有必要”时，反意疑问句用needn't，例如：
You
must
see
him
tonight,meedn't
you?
c.当must表示“一定”或“想必”等推测意义时，反意疑问部分不用mustn't，而根据must后的动词形式而定。例如：
He
must
be
crazy
to
do
so,isn't
he?
She
must
have
been
there
for
a
long
time,hasn't
she?
They
must
have
stayed
at
home
last
might,didn't
they?
4
当陈述部分带有need时，反意疑问部分需视need的含义而定。如果need用作情态动词，则反意疑问部分用need形式；如果need用作实义动词，表示“需要”，则反意疑问部分用do形式。例如：
You
needn't
go
there,need
you?
She
needs
to
fo
there,doesn't
she?
Plants
need
sun
to
grow,don't
they?
