Dear
Marry,
Today
is
my
first
day
in
England
and
I
learned
something
interesting
about
the
weather
here.
It’s
was
cold
in
the
morning.
The
weather
report
said
the
temperature
was
only
15
degree
Celsius,
so
I
put
on
lots
of
clothes
before
I
went
to
my
new
school.
But
when
I
was
outside,
the
weather
quickly
changed.

The
clouds
went
away;
the
sky
turned
blue
and
the
sun
started
to
shine.
I
was
hot!
Then
at
lunchtime,I
wanted
to
go
to
the
playground,
but
the
sky
was
black
and
it
was
raining
hard.
I
had
no
umbrella,
I
thought,“How
can
I
go
home
after
school?“
but
when
school
finished
at
3
p.m,
there
was
no
rain.
Now
it
was
very
windy
and
cool.
I
put
on
my
coat
and
walked
home.
So
it’s
really
true.
In
England,
you
can
have
four
seasons
in
