We should be careful with
electricity
As we
all know, electricity plays an important part in
our daily life.
It
’
s hard to
imagine what our life would be like without it.
But it
’
s also
dangerous in a way. According to a
survey, thousands of people die from
electricity
every
year,
and
most
of
them
are
teenagers
and
children,
because they are
always careless and they
don
’
t have enough common
knowledge. Therefore,
it
’
s important for us to be
careful with electricity.
For
example,
we
need
to
keep
our
hands
dry
when
we
use
electrical
appliances.
Electricity is a
good servant, but a dangerous one. If we deal with
it
carefully, we will have a better
life.
We should be careful
with
chemicals
Chemicals
are
quite
useful
in
our
daily
life.
They
create
our
wonderful world. However, they are very
dangerous, too. They will hurt
people
if
we
use
them
carelessly.
Chemicals
will
also
pollute
the
environment,
so
we
should
always
be
careful
with
them,
especially
in
labs.
And
we
must
clean
the
sewage
that
contains
chemicals
before
it
flows
into the river.
Chemicals
are
good
helpers
but
they
are
dangerous.
Let
’
s
pay
attention to chemicals.
