Answer 3

相同点：都可以作形容词、代词，如(都是词霸上的例子)
1.
Both
guests
have
arrived.
Both
the
books
are
torn.
Both
her
fingers
are
broken.
All
the
windows
are
open.
Deal
all
the
cards.
注意：both和all作形容词修饰名词，在有冠词的情况下放在冠词前，这一点和其他形容词不同。例如，all
the
world
和
the
whole
world
2.
Both
were
candidates.
We
are
both
candidates.
Both
of
us
are
candidates.
All
that
I
have
is
yours.
We
are
all
Chinese.
All
of
us
are
sick.
3.
与否定词“not”连用时只表示部分否定，而且不要被“not”灵活的位置迷惑，应理解为“不是所有的…都…”
不同点：both可作连词，all可作副词，如
1.
both
men
and
women;
an
attorney
well
regarded
for
both
intelligence
and
honesty.
2.
a
room
painted
all
white;
directions
that
were
all
wrong.
all能修饰形容词
2.
数量上：both固定是“两、双”，而all表示“三个或三个以上”
