Scientists
in
Western
Australia
claim
to
have
made
a
new
discovery—they
have
found
gold
in
the
leaves
and
twigs
of
trees.
The
researchers
believe
that
the
trees
suck
up
the
gold
from
deep
underground，over
30
metres
down.
The
discovery
has
been
described
as
the
first
of
its
kind
in
the
world.
Australian
gold
exploration
companies
are
pleased
because
it
will
make
finding
gold
cheaper.
Rather
than
drilling
deep
holes
to
find
gold，they
have
more
ways
to
examine
tree
leaves
and
branches.
There
is
only
a
tiny
amount
of
gold
in
the
leaves.
It
would
take
500
trees
to
make
one
gold
ring.
The
gold
is
found
using
a
special
X—ray
machine
owned
by
an
Australian
government
agency.
A
pure
X-ray
and
a
powerful
microscope
scan
the
leaves
and
branches.
The
claim
that
this
is
the
first
time
that
gold
particles(微粒)have
been
found
in
living
material
might
not
be
true，though.
Ancient
Chinese
wisdom
understood
the
connection
between
plants
and
the
precious
stones
and
minerals
underneath
them.
They
used
plant
life
to
find
minerals
and
that
was
thousands
of
years
ago.
In
the
Zhou
Dynasty，it
was
written
in
a
book
that
a
certain
plant
grew
only
near
deposits
of
gold.
Over
the
next
2，000
years，Chinese
people
wrote
about
different
plants
and
how
they
grew，showed
where
minerals
and
precious
stones
such
as
jade，copper，lead，silver
and
gold
were.
Even
more
importantly，in
the
1
000s，Su
Song
described
how
copper，gold，silver，lead
and
tin
were
observed
and
taken
from
certain
plants.
These
were
amazing
scientific
discoveries.
Meanwhile，this
knowledge
was
unknown
in
the
rest
of
the
world
until
about
1
600.This
was
when
a
British
man
realised
that
oak
trees
grew
larger
and
greener
where
there
was
alum(明矾)in
the
ground.
Maybe
ancient
Chinese
has
more
knowledge
to
teach
modern
scientists.
1.
What
can
we
know
from
Paragraph
1
?
A.
500
dead
trees
can
make
one
gold
ring.
B.
The
trees
can
absorb
the
gold
from
deep
underground.
C.
Scientist
have
found
gold
30
meters
below
underground.
D.
The
companies
find
it
hard
to
find
gold.
2.
How
do
scientists
find
gold
in
the
leaves?
A.
By
observing
the
leaves
carefully.
B.
By
drilling
deep
holes.
C.
By
using
a
special
x-ray.
D.
By
referring
to
ancient
books.
3.
Who
first
discovered
that
there
was
connection
between
plants
and
minerals?
A.
Ancient
Chinese
people.
B.
Su
Song.
C.
Australian
scientists.
D.
A
British
man.
4.
What
is
the
purpose
of
the
last
paragraph?
A.
To
introduce
two
great
scientists
in
ancient
times.
B.
To
provide
more
evidence
to
support
the
writer’s
opinion.
C.
To
show
how
ancient
people
got
gold
from
certain
plants.
D.
To
prove
that
ancient
Chinese
has
more
knowledge
than
modern
scientists.

【解析】这是一篇说明文。文章主要说明了散步对人的一些好处，以及如何选择散步路线的建议。从对你的心脏的好处到你整体的快乐，步行对你来说是非常好的。文章最后倡导人们开始步行起来。
1.
E.
根据上文Humans
were
made
for
walking.
With
our
upright
posture
and
strong
leg
muscles,
our
bodies
were
actually
designed
with
walking
in
mind
which
makes
it
such
perfect
exercise.
It’s
kind
to
our
bodies
and
great
for
our
waistlines.可知，人是为行走而生的。由于我们直立的姿势和强壮的腿部肌肉，我们的身体实际上是为步行而设计的，这使得步行成为一种完美的锻炼。它对我们的身体有好处，对我们的腰围也有好处。由此可知，本句承接上文继续说明步行的好处。故E选项“最重要的是，这是一个认识新事物和认识新朋友的好方法!”符合上下文语境，故选E。
2.
D.
结合后文Ask
yourself,
what
do
you
want
to
get
out
of
walking
aside
from
the
health
benefits?
Do
you
want
to
meet
other
people?
See
new
places?
Get
out
into
the
countryside
or
explore
a
new
city?
Knowing
your
goals
will
help
you
decide
on
the
type
of
walk
you
want
to
do.可知，问问你自己，除了健康益处，你还想从散步中得到什么？你想认识其他人吗？看到新地方吗？走出家门去乡下还是去探索一个新的城市？了解你的目标将帮助你决定你想要走的类型。由此可知，本句是在说明要带着目标步行，后文一系列设问句是在解释如何寻找目标。故选D项“不管怎样，现在是时候接受带着目标走路的想法了”符合上下文语境，故选D。
3.C.
根据上文If
making
friends
and
socializing
is
your
goal,
call
up
your
friends
and
schedule
walks
with
them.可知，如果交朋友和社交是你的目标，打电话给你的朋友，安排和他们一起散步。由此可知，如果想要和朋友一起散步社交，那么需要了解他们喜欢去哪里散步。故C选项“问问你的朋友他们喜欢去哪里散步，然后就去那里”符合上下文语境，故选C。
4.
G.
根据后文Many
large
cities
have
incredible
gardens
and
parks
that
include
quiet
walking
trails
getting
you
off
the
beaten
path.可知，许多大城市都有令人难以置信的花园和公园，里面有安静的步行道，让你远离人迹罕至的小路。由此可知，本段是在说明如果想一个人散步，可以选择的散步地点是离开城镇后安静的步行道。故G选项“如果你想一个人散步，可以问问当地的徒步旅行，这样你就可以离开城镇，去乡下了”符合上下文语境，故选G。
5.B.
根据上文From
the
benefits
to
your
heart
to
your
overall
happiness,
walking
is
just
plain
good
for
you.可知，从对你的心脏的好处到你整体的快乐，步行对你来说是非常好的。结合本段为文章最后一段，有总结上文的作用，上文提到了散步的好处和选择，那么此处应当是倡导人们开始步行。故B选项“这个月，拿起一张地图，开始步行”符合上下文语境，故选B。
V:
阅读理解。阅读下面短文，从短文后各题所给的A、B、C和D四个选项中，选出可以填入空白处的最佳选。
Scientists
in
Western
Australia
claim
to
have
made
a
new
discovery—they
have
found
gold
in
the
leaves
and
twigs
of
trees.
The
researchers
believe
that
the
trees
suck
up
the
gold
from
deep
underground，over
30
metres
down.
The
discovery
has
been
described
as
the
first
of
its
kind
in
the
world.
Australian
gold
exploration
companies
are
pleased
because
it
will
make
finding
gold
cheaper.
Rather
than
drilling
deep
holes
to
find
gold，they
have
more
ways
to
examine
tree
leaves
and
branches.
There
is
only
a
tiny
amount
of
gold
in
the
leaves.
It
would
take
500
trees
to
make
one
gold
ring.
The
gold
is
found
using
a
special
X—ray
machine
owned
by
an
Australian
government
agency.
A
pure
X-ray
and
a
powerful
microscope
scan
the
leaves
and
branches.
The
claim
that
this
is
the
first
time
that
gold
particles(微粒)have
been
found
in
living
material
might
not
be
true，though.
Ancient
Chinese
wisdom
understood
the
connection
between
plants
and
the
precious
stones
and
minerals
underneath
them.
They
used
plant
life
to
find
minerals
and
that
was
thousands
of
years
ago.
In
the
Zhou
Dynasty，it
was
written
in
a
book
that
a
certain
plant
grew
only
near
deposits
of
gold.
Over
the
next
2，000
years，Chinese
people
wrote
about
different
plants
and
how
they
grew，showed
where
minerals
and
precious
stones
such
as
jade，copper，lead，silver
and
gold
were.
Even
more
importantly，in
the
1
000s，Su
Song
described
how
copper，gold，silver，lead
and
tin
were
observed
and
taken
from
certain
plants.
These
were
amazing
scientific
discoveries.
Meanwhile，this
knowledge
was
unknown
in
the
rest
of
the
world
until
about
1
600.This
was
when
a
British
man
realised
that
oak
trees
grew
larger
and
greener
where
there
was
alum(明矾)in
the
ground.
Maybe
ancient
Chinese
has
more
knowledge
to
teach
modern
scientists.
1.
What
can
we
know
from
Paragraph
1
?
A.
500
dead
trees
can
make
one
gold
ring.
B.
The
trees
can
absorb
the
gold
from
deep
underground.
C.
Scientist
have
found
gold
30
meters
below
underground.
D.
The
companies
find
it
hard
to
find
gold.
2.
How
do
scientists
find
gold
in
the
leaves?
A.
By
observing
the
leaves
carefully.
B.
By
drilling
deep
holes.
C.
By
using
a
special
x-ray.
D.
By
referring
to
ancient
books.
3.
Who
first
discovered
that
there
was
connection
between
plants
and
minerals?
A.
Ancient
Chinese
people.
B.
Su
Song.
C.
Australian
scientists.
D.
A
British
man.
4.
What
is
the
purpose
of
the
last
paragraph?
A.
To
introduce
two
great
scientists
in
ancient
times.
B.
To
provide
more
evidence
to
support
the
writer’s
opinion.
C.
To
show
how
ancient
people
got
gold
from
certain
plants.
D.
To
prove
that
ancient
Chinese
has
more
knowledge
than
modern
scientists.
【答案】1--4
BCAB
【语篇解读】这是一篇议论文。澳大利亚西部的科学家们声称有了一项新发现——他们在树叶和树枝中发现了金子，这一发现被描述为世界上第一个类似的发现。但作者认为第一次在生命物质中发现金子微粒的说法可能是不正确的，并证实了这种观点。
1.B
【解析】细节理解题。由第一段“The
researchers
believe
that
the
trees
suck
up
the
gold
from
deep
underground，over
30
metres
down.”可知，研究人员相信这些树能从30米以下的地下深处吸收黄金。所以从第一段我们可以知道树木能从地下深处吸收金子。故B选项正确。
2.C
【解析】细节理解题。由第一段“The
gold
is
found
using
a
special
X—ray
machine
owned
by
an
Australian
government
agency”可知，黄金是用澳大利亚政府机构拥有的一台特殊的X光机来发现的。所以科学家用特殊的x射线来寻找树叶中的金子。故C选项正确。
3.A
【解析】细节理解题。由第二段“Ancient
Chinese
wisdom
understood
the
connection
between
plants
and
the
precious
stones
and
minerals
underneath
them.
They
used
plant
life
to
find
minerals
and
that
was
thousands
of
years
ago.”可知，中国古代的智慧了解植物和其下面的宝石和矿物之间的联系。他们用植物来寻找矿物，那是几千年前的事了。所以中国古代人民首先发现植物和矿物之间有联系。故A选项正确。
4.B【解析】推理判断题。由最后一段可知，重要的是，在11世纪，苏松描述了铜、金、银、铅和锡是如何被观察到并从某些植物中被提取出来。这些都是令人惊奇的科学发现。同时，直到1600年左右，世界其他地方都不知道这一知识。这时一个英国人意识到橡树变得更大更绿。在其下面发现了明矾，也许古代中国人有更多的知识来传授给现代科学家。所以最后一段，仍然在说明在生命物质中发现金子微粒很早就已经存在了。所以第一次在生命物质中发现金子微粒的说法是不正确的。故最后一段的目的是提供更多的证据来支持作者的观点。故B选项正确。
