2.
Which
story
has
also
been
mentioned
and
questioned?
A．Franklin's
life
story.
B．Franklin's
work
as
a

theory
of
gravity
.
有些人甚至质疑已被大家接受的观点，因为他们想要建立事实。
一些人甚至质疑苹果掉在牛顿头上导致他提出万有引力理论的故事。

3．What
people
are
inspired
for
in
Franklin's
story?
____________________
More
than
one
gengration
of
schoolchildren
has
been
amazed
by
his
bravery
and
his
scientific
approach
to
looking
for
the
truth
.

However
,neither
the
story
nor
the
details
of
the
experiment
are
entirely
ture
.The
detail
about
the
string
and
the
key
is
true
.
Scientist
all
agree
that
if
Franklin
had
actually
touched
the
key
,he
would
certainly
have
died
from
the
electric
shock
.(虚拟语气）
然而，这个故事和实验的细节都不是完全真实的，关于绳子和钥匙的细节都是真实的。
科学家们一致认为，如果富兰克林真的碰了那把钥匙，他肯定会死于电击。
5．What

A．The
scientists
didn't

was
certainly
inspired
by
a
falling
apple
,there
is
no
proof
that
it
hit
him
on
the
head
.(同位语从句）
事实上，不止一种说法表明，虽然牛顿的确是受到了掉落的苹果的启发，但没有证据表明苹果砸中了他的头部。
