The
History
of
Sandwiches
Sandwich本来是英国东南部一个不出名的小镇，镇上有一位名叫John
Montagu的伯爵，他整天沉溺于纸牌游戏中，已经到了废寝忘食的地步。仆人很难侍候他的饮食，便将一些菜肴、鸡蛋和腊肠夹在两片面包之间，让他边玩牌边吃饭。没想到John见了这种食品大喜，并随口就把它称作“sandwich”，以后饿了就喊：“拿sandwich来!”
其他赌徒也争相仿效，玩牌时都吃起sandwich来。不久，sandwich就传遍了英伦三岛，并传到了欧洲大陆，后来又传到了美国。sandwich已成为当今西方主要的快餐食品之一。

Let's
look
at
two
old
but
popular
inventions
we
use
in
our
daily
life.
Band－Aids(创可贴)
The
first
Band－Aid
was
made
by
American
Earle
Dickson
in
1921.The
idea
came
to
him
by
chance.
Dickson's
wife
often
cut
her
fingers
in
the
kitchen.
At
that
time
gauze(纱布)
and
adhesive
tape
(胶带)didn't
come
together.
People
had
to
cut
them
to
the
right
size.
Dickson
found
they
were
always
too
big
and
soon
fell
off.
So
he
put
a
piece
of
gauze
on
the
center
of
a
piece
of
tape.
This
is
how
he
made
the
first
Band-Aid.
Later，Dickson's
new
inventions
became
very
popular
all
around
the
world.
Bubble
gum(泡泡糖)
Bubble
gum
was
invented
by
accident.
In
1928，American
gum
company
worker
Walter
E.
Diemer
played
around
with
new
chewing
gum
recipes（口香糖配方）.
Chewing
gum
had
already
been
invented
more
than
half
a
century
before
then.
But
Diemer
found
that
the
gum
he
made
was
easy
to
blow.
He
blew
a
bubble
and
then
saw
the
possibilities.
He
took
some
of
his
new
gum
to
a
shop
and
it
sold
out
in
a
single
afternoon.
Since
then，Dubble
Bubble—the
first
brand
of
bubble
gum—has
made
kids
happy
all
around
the
world.
