Wind
—
even
the
slightest
of
winds
can
prevent
frost
(
霜冻
< br>).T
hat’s
because wind is
like a spoon in your cup of tea: it stirs
（搅起）
things
down
and
brings
down
a
lot
of
warm
air
that
often
floats
just
above
housetops and trees .
It may seem strange , but ice itself
sometimes can protect crops from
frost
. Some growers actually spray their crops with
water on a freezing
night . Water
freezes quickly on plants and then a strange thing
happens .
As
long
as
ice
stays
wet
,
it
can’t
get
colder
than
32
°
F,
a
temperaure
many
plants
can
stand
.
By
continual
spraying
water
on
the
ice
,
the
growers
keep
it
from
going
below
32
degrees
even
if
the
air
is
much
colder . This may
defeat frost and saves plants .
This
strange kind of “ice blanket” works only on plants
that are st
rong
enough to
stand the weight of frozen spray . This is used
even to protect
banana plants on some
Central American farms .

In
which of the following sentences “stand” has the
same meaning as
in the last paragraph ?
A
．

Build
the
highway
and
watch
the
town
grow .
At
first
a
few
shops
appear
and
maybe
a
restaurant .
Then
a
hotel
opens .
Eventually
new
houses are built . A village is born .
This
is
also
how
the
virtual
world
has
developed
.
Think
of
the
Internet
as the road carrying information between two
computers . Think
of the World Wide Web
as the village . At first it is just a place on
the
virtual
road
where
travelers
meet .
More
travelers
come
bringing
new
kinds of information . New villages are
started .
Every village has a founder .
Tim Berners Lee is the man who wrote
the software program that led to the
foundation of the World Wide Web .
How
did he get the idea ? H
e tells us on
his own website : “ One of the
things
computers
were
not
able
to
do
was
store
contacts
from
different
sources . The
dream behind the Web is of a common space in which
we
communicate by sharing
information.”
Tim Berners
Lee could have followed the Microsoft route by
forming
a company to sell the programs
he invented . Or he could have joined an
existing company . But in his view the
Web is a language , not a product .
Charging a fee for using his programs
would have slowed the growth of
the Web
. And other companies would make similar products
to compete .
Instead of one World
Wide Web there would be several smaller
Webs .
Each would use incompatible
（
不相容的）
software .
The Web is valuable
because it uses a
common computer language to reach people and share
information
.
Competing
Webs
would
lose
this
value
.Imagine
if
somebody sent you a bill every time you
spoke a word of English .
In 1994 Tim
Berners Lee formed World Wide Web Consortium , or
B
W3C. More than 200 leading
companies and laboratories are represented
by
W3C.
Together
they
make
sure
that
everyone
no
matter
what
their
equipment or software is can work
equally on the Web .
“The Web can help
people to understand the way that others live and
love . It helps us understand the
humanity of peopl
e ,” he says
.
