Answer 1

The
general
opinion
abroad
is
that
London
has
fog
or
rain,or
both,every
day
of
the
year,but
on
the
day_____I
arrived
it
was
very
fine
and
warm.
A.that
B.which
从语法角度讲，which后面一般都要加逗号，变成on
the
day,which
i
arrived,it
was
fine
and
warm.
Unlike
sound,light
can
travel
in
a
vacuum,in
empty
space___there
is
not
even
air.
A.that
B.where
there
is
not
even
air指定的是一个环境/场地/地区，所以要用where
All
that
you
do,do
with
your
might.Things
done
by
halves
are
never
done
right.
翻译了大概就是：如果决定了要做一件事就付出全部力量。半途而废绝不会正确的解决事情。
He
had
made
another
wonderful
discovery,_____of
great
important
to
science.
A.Which
I
think
is
B.Which
I
think
it
is
这里选A是因为"it"就是"wonderful
discovery"，既然前半句已经提起了，而且还在描述它，就不应该再重复的用it
Almost
all
metals
are
conductors
of
electricity,____has
been
stated
above.
A.as
B.which
后半句：由以上所述
其实这题的选项很暧昧（笑），其实两个都可以用。如果一定要解释的话，as
就像
like，后半句就变成了“就像上述的”。
Can
you
name
a
few
more
electrical
appliances______electricity
is
used
to
produce
heat？
A.as
B.where
跟刚刚的那道一样，用电制造热量也是一种特定环境，所以要用where。as换成like填进去的话不通顺。
An
investigation
was
made
into
the
accident,(in
which)fifty
people
were
killed.
因为要说in
the
accident
fifty
ppl
were
killed.
which
就是the
accident的另一种说法，因为前面已经说过the
accident了，为了不重复用词，改为which
