But

even

the____
scientific

and
statistical
analysis,

place.
To

the
conflict
between
statistics
and
,scientists
often
have
to

think

the
problem
from
different
directions.
They
must
have
a
vivid
imagination
and
a
strong
intuition
in
order
for
new
to
be
made.
It
echoes
something

__
Carl

and
every

Activity
2
(PPT15-19)
Task1
Fill
in
each
blank
with
a
word
or
impression
that
introduces
a
predicative
clause.
Science
is
simply
you
can
do.
And
doing
science
makes
you
a
scientist!
So,
what
do
scientists
do?
Actually,
what
matters
is
not
only
they
observe
in
the
world
around
them
and
what
questions
they
ask,but
also
they
use
evidence
or
data
to
answer
the
questions.
They
identify
useful
data
and
take
new
measurements.
Some
of
the
key
issues
that
scientists
face
are
calculations
they
do
and
they
analyse
their
data
to
draw
conclusions
about
the
questions
they
ask.
The
final
issue,which
many
believe
to
be
the
most
important,
is
they
need
to
communicate
their
results.
This
is
they
want
everyone
to
benefit
from
their
work!
It
seems
____
science
is
all
around
us.You
see,
by
doing
science
,
scientists
get
a
better
understanding
of
the
world
around
them
and
share
that
understanding
with
the
whole
world.

calculations
they
do
and
how
they
analyse
their
data

about
the
questions
they
ask.
4.The
final
issue...

is
the
passage
about?
2.What
is
the
author's
opinion?
3.Do
you
agree
with
the
author?
What
is
your
opinion?
Answers:
It
is
about
what,
how
and
why
the
scientists
do.
Scientists
use
evidence
to
prove
some
calculations
and
want
everyone
to
benefit
from
their
works.
Yes,I
can't
agree
the
author
any
more.
Doing
some
research
is
not
so
easy.It
needs
scientists
to
have
good
qualities
like
curiosity,creativity,
imagination
and
intuition.And
most

Science

And
doing
science
makes
you
a
scientist!
So,
what
do
scientists
do?
Actually,
what
matters
is
not
only
they
observe
in
the
world
around
them
and
what
questions
they
ask,but
also
they
use
evidence
or
data
to
answer
the
questions.
They
identify
useful
data
and
take
new
measurements.
Some
of
the
key
issues
that
scientists
face
are
calculations
they
do
and
they
analyse
their
data
to
draw
conclusions
about
the
questions
they
ask.

by
