watermelon既是可数，又是不可数
watermelon（西瓜），如果作为一个整体的话，则可以是可数名词，这时候就应该加s，
如：There
are
four
watermelons
有两个西瓜。
但如果我们提到这些食物的时候，都是要吃的，在这时候就作为不可数了，所以当你说想要吃些西瓜的时候就应该说：
I'd
like
some
watermelon
在这种情况下，watermelon是作为不可数名词，所以是不加s的。
两句话都可以说，但意思不一样。I
like
wartermelons是指你喜欢作为一个完整体的西瓜，比如它的形状颜色等等，这时的watermelon是可数的。而
I
like
watermelon
是指你喜欢吃西瓜。因为这时的西瓜是已经切成块的西瓜，是不可数的。看看老外是怎么解释的:
In
which
situation
do
you
use
:1
I
like
watermelons
2
I
like
watermelon
It
would
be,
"I
like
watermelon"
The
reason
is
that
when
the
watermelon
fruit
is
whole
--
has
not
been
cut
yet
--
it
is
countable
You
could
say,
"They
stacked
up
several
watermelons"
However,
after
the
fruit
has
been
sliced
up
for
eating,
it
becomes
uncountable
You
could
say,
"There
was
a
lot
of
watermelon
on
the
table"
If
you
say,
"I
like
watermelons,"
it
means
there
is
something
you
like
about
the
whole
fruit,
such
as
the
shape
or
color,
or
the
noise
it
makes
when
you
knock
it
If
you
say,
"I
like
watermelon,"
it
means
that
you
like
to
eat
it
watermelon西瓜
watermelon 既作为可数名词,也作为不可数名词一个个的西瓜就是可数;把西瓜切成许多半,就是不可数,表示为 a piece of watermelon
