Ⅱ.完形填空
Always
wished
the
Earth
had
a
second
moon?
Then
you
will
be
__1__
to
hear
that
the
Chengdu
Aerospace
Science
Institute
has
plans
to
launch
multiple
mini
moons
over
the
next
few
years.
Similar
to
our
__2__
satellite,
the
light
of
the
artificial
orb
(球体)
will
be
obtained
from
the
sun
and
__3__
to
Earth
by
its
mirror?like
coating.
According
to
its
designers,
the
amount
of
light
being
reflected
can
be
controlled
from
Earth
and
the
light
can
even
be
__4__，
if
necessary.
While
the
multiple
mini
moons
will
certainly
appear
picturesque,
their
main
purpose
is
to
conserve
resources.
The
Chengdu
Aerospace
experts
claim
the
mini
moon's
dusk?like
glow
will
allow
the
government
to
eventually
__5__
costly
streetlights
in
cities.
They
estimate
that
using
the
artificial
satellite
to
light
up
Chengdu's
streets
at
night
will
__6__
the
city
1.2
billion
yuan
annually.
Since
the
orb's
location
can
be
easily
moved,
it
could
also
be
used
to
shine
light
over
disaster?struck
areas
that
have
lost
__7__.
Once
the
first
mini
moon
is
__8__
successfully,
the
experts
plan
to
launch
three
__9__
ones.
Together,
the
satellites,
which
will
take
turns
depending
on
their
__10__
in
relation
to
the
sun,
are
expected
to
__11__
an
area
of
3,600
to
6,400
square
kilometers.
While
the
orbs
will
be
__12__
through
a
telescope
from
anywhere
on
the
globe,
their
real
beauty
will
only
be
seen
by
visiting
Chengdu.
Officials,
therefore,
believe
they
will
be
a
huge
tourist
attraction,
helping
improve
the
city's
economy.
As
is
often
the
case
with
major
__13__，
some
experts
are
concerned.
They
__14__
that
the
moons
will
impact
on
the
sleep
patterns
of
humans
and
animals.
However,
officials
believe
the
satellites
will
cause
little,
if
any

A
It's
easy
to
think
that
the
globe's
vast
oceans
would
be
effective
barriers
to
the
movement
of
land
animals.
An
elephant
can't
swim
across
the
Pacific,
after
all.
But
it
turns
out
that
plenty
of
plants
and
animals
have
unintentionally
floated
across
oceans
from
one
continent
to
another.
Now
comes
evidence
that
tiny,
trapdoor
(活板门)
spiders
made
such
a
journey
millions
of
years
ago.
Moggridgea
rainbowi
spiders
can
be
found
on
Kangaroo
Island,
which
sits
off
the
south
coast
of
Australia.
These
spiders
build
a
silk?lined
burrow
(地洞)
in
the
ground,
notes
Sophie
Harrison,
a
biologist
in
Australia.
The
burrow
and
trapdoor
provide
these
spiders
with
shelter
and
protection.
It
also
provides
them
an
out?of?sight
spot
from
which
to
wait
for
approaching
preys
(猎物)．
There
is
evidence,
though,
that
the
ancestors
of
them
might
have
traveled
millions
of
meters
to
get
to
Australia
from
Africa.
That
isn't
as
unlikely
as
it
might
at
first
seem.
Australia
used
to
be
connected
to
other
continents,
long
ago,
as
part
of
a
supercontinent
called
Gondwana.
And
humans
have
been
known
to
transport
species
all
over
the
planet.
But
there's
a
third
option.
The
spiders
might
have
rafted
(乘筏)
long
distances
across
the
sea.
To
figure
out
which
story
was
most
likely
true,
Harrison
and
her
colleagues
looked
at
the
spider's
genes.
They
looked
at
the
genes
in
seven
Moggridgea
rainbowi
spiders
from
Kangaroo,
and
five
species
of
Moggridgea
spiders
from
South
Africa.
The
Australian
and
African
spiders
split
off
from
a
common
ancestor
some
2
million
to
16
million
years
ago,
the
genes
showed.
If
a
large
block
of
land
washes
into
the
sea,
filled
with
arachnids
(蛛形纲动物),
the
spiders
may
be
able
to
hide
themselves
throughout
the
journey.
Plus,
they
can
“hold
their
breath”
and
survive
on
stored
oxygen
during
periods
of
temporary
flooding,
the
researchers
note.
本文是一篇说明文。研究发现，现在生活在澳大利亚的Moggridgea
rainbowi
spiders与非洲的Moggridgea
spiders基因相同，应该衍生于同一祖先。

unlikely

C．They

at
the
genes
in
seven
Moggridgea
rainbowi
spiders
from
Kangaroo,
and
five
species
of
Moggridgea
spiders
from

B
In
his
book
The
Tipping
Point
Canadian
author
Malcolm
Gladwell
explains
how
a
trend
can
take
many
forms.
It
can
be
a
general
change
in
social
behaviour,
an
idea
or
a
fashion.
However,
why
do
some
trends
catch
on
and
others
not?
What
makes
one
particular
brand
of
training
shoe
suddenly
become
the
must?have
product?
How
do
people
find
out
about
trends
and
what
makes
people
want
to
buy_into
them?
Is
it
simply
a
question
of
keeping
up
with
other
people?
In
his
new
work,
Gladwell
explores
the
moment
when
something
becomes
common
and
how
products,
ideas,
messages
and
forms
of
behaviour
spread.
He
looks
at
the
reasons
why
trends
are
similar
in
the
way
they
develop
to
outbreaks
of
disease,
or
medical
epidemics
(流行病)．
Epidemics,
like
trends,
start
in
a
very
small
way,
maybe
from
a
single
person
with
a
virus,
then
spread
very
quickly
until
they
take
over
the
population
and
appear
to
be
everywhere.
Eventually,
they
will
slow
down
gradually
or
die
out
suddenly.
Gladwell
shows
how
these
changes
happen
not
gradually
but
at
one
sudden
moment.
Gladwell
identifies
three
types
of
people
who
are
influential
in
the
development
of
these
kinds
of
social
epidemics：
Connectors
are
people
in
a
community
who
have
wide
social
circles.
They
know
a
lot
of
people
and
like
to
introduce
people
to
each
other.
The
people
they
know
often
come
from
a
variety
of
social,
cultural,
professional
and
economic
circles.
Mavens
are
people
with
a
lot
of
knowledge
or
experts
in
a
particular
field.
They
wish
to
pass
on
their
knowledge
to
others.
Mavens
collect
and
gather
information
so
they
are
the
first
to
pick
up
on
new
trends.
Salesmen
are
people
with
charisma
(魅力).
They
have
a
“soft”
influence
over
people
rather
than
actual
power.
This
means
they
are
influential
because
people
want
to
imitate
them.
Overall,
Gladwell's
book
is
a
thought?provoking
(引人深思的)
read
for
anyone
interested
in
the
origins
of
trends.
What's
more,
he
writes
in
a
clear
style
so
even
the
most
difficult
ideas
are
easy
to
understand.
本文是对Malcolm
Gladwell的新作The
Tipping
Point的书评。
5．What
does
the
underlined
part
“buy
into”
in
Paragraph
1
mean?
A．Pay
money
for.
B．Gain
control
of.
C．Keep
the
same
level
as.
D．Believe
in
and
be
influenced
by.
答案：D
解析：词义猜测题。由第一段中的“What
makes
one
particular
brand
of
training
shoe
suddenly
become
the
must?have
product？”和“keeping
up
with
other
people”可知，人们能够发现潮流并跟随潮流。由此可推断，buy
into意为“相信并被其影响”。
6．What
do
we
know
about
Gladwell?
A．He
is
a
productive
North
American
writer.
B．He
has
written
many
books
on
the
subject
of
trends.
C．He
thinks
trends
develop
in
the
same
way
as
illnesses.
D．He
believes
there
are
three
types
of
people
in
the
world.
答案：C
解析：推理判断题。由第二段中的“He
looks
at
the
reasons
why
trends
are
similar...medical
epidemics
(流行病)．”以及第三段的描述可知，Gladwell认为潮流的发展与疾病(尤其是流行病)的爆发非常相似。
7．According
to
the
text,
connectors
________.
A．often
follow
others
B．are
very
social
persons
C．are
knowledgeable
and
experienced
D．know
many
people
from
the
same
circle
答案：B
解析：细节理解题。由第五段中的“Connectors
are
people
in
a
community
who
have
wide
social
circles.
They
know
a
lot
of
people
and
like
to
introduce
people
to
each
other.”可知，connectors擅长社交生活。
8．What
do
we
know
from
the
text?
A．Mavens
quickly
become
aware
of
changes
in
fashions.
B．Salesmen
try
to
control
other
people
using
their
power.
C．Connectors
and
Mavens
try
to
get
their
information
across.
D．This
book
is
interesting
but
hard
to
understand
for
readers.
答案：A
解析：细节理解题。由倒数第三段中的“Mavens
collect
and
gather
information
so
they
are
the
first
to
pick
up
on
new
trends.”可知，Mavens能够迅速意识到时尚的变化。

Ⅰ.阅读理解
Zhoukoudian
is
a
small
village
situated
about
50
kilometers
to
the
southwest
of
Beijing.
In
the
1920s,
archaeologists
discovered
some
prehistoric
human
bones
there
which
changed
people's
view
of
China's
history.
They
came
from
an
unknown
species
of
man
and
were
the
first
evidence
of
human
life
in
China
thousands
of
years
ago.
The
remains
were
three
teeth!
In
1929,
a
complete
skull
was
also
discovered.
Eventually,
archaeologists
found
almost
200
items,
including
six
skulls
and
more
than
150
teeth.
These
discoveries
proved
the
existence
of
a
human
species
that
lived
in
the
area
between
700,000
and
200,000
years
ago.
Four
sites
where
Beijing
Man
and
his
relatives
lived
were
discovered
on
the
northern
face
of
Longgushan.
They
lived
in
the
caves
in
the
area.
However,
the
life
span
of
Beijing
Man
was
short.
About
70%
of
the
people
probably
died
before
the
age
of
14.
Fewer
than
5%
lived
to
the
age
of
50.
Ashes
were
found
alongside
the
fossils
which
showed
they
had
used
fire
for
cooking
food
and
also
for
light,
warmth,
and
protection
against
wild
animals.
This
is
the
earliest
evidence
of
the
use
of
fire
anywhere
in
the
world.
They
also
made
tools
of
bones
and
stones.
Unfortunately,
when
Japan
invaded
China
in
1937,
excavations
at
the
Beijing
Man
Site
stopped
and
most
of
the
fossils
disappeared,
including
a
Beijing
Man
skull.
After
the
People's
Republic
of
China
was
established
in
1949,
the
work
started
again.
Zhoukoudian
was
listed
as
a
World
Heritage
Site
in
December
1987.
It
has
not
only
given
us
important
information
about
prehistoric
Asian
societies,
but
also
provided
amazing
evidence
about
the
process
of
evolution.
Today,
parts
of
the
caves
have
been
badly
affected
by
rain.
Some
areas
are
almost
completely
covered
in
weeds,
causing
serious
damage.
Pollution
from
the
nearby
factories
has
also
contributed
to
the
problem.
This
is
a
very
serious
matter
and
the
Chinese
Academy
of
Sciences
is
trying
to
raise
public
awareness
of
it.
文章向我们介绍了周口店“北京人”遗址，它的位置、发现过程以及考古意义。
1．Archaeologists
________.
A．thought
that
Zhoukoudian
was
a
beautiful
village
B．thought
that
the
findings
in
Zhoukoudian
wouldn't
change
the
history
of
China
C．discovered
some
prehistoric
human
bones
in
Zhoukoudian
D．thought
that
the
findings
in
Zhoukoudian
are
the
first
evidence
of
human
life
in
Asia
答案：C
解析：细节理解题。根据第一段中的“In
the
1920s,
archaeologists
discovered
some
prehistoric
human
bones
there
which
changed
people's
view
of
China's
history.”可知答案。
2．Which
of
the
following
statements
is
NOT
true?
A．The
digging
was
delayed
by
the
Japanese
invasion
in
the
1930s.
B．These
ancient
Chinese
were
the
first
people
to
use
fire
in
daily
life.
C．Some
valuable
things
excavated
from
the
site
are
still
missing.
D．The
digging
of
Zhoukoudian
is
famous
and
is
well?funded.
答案：D
解析：推理判断题。根据最后一段后半部分描写的情况，长期以来，风吹雨淋、杂草丛生、破烂不堪。说明是没有进行修复，没有提得到资助的情况。故选项D说法是错误的。
3．What's
the
main
idea
of
the
last
paragraph?
A．The
digging
of
Zhoukoudian
is
still
under
way.
B．Zhoukoudian
plays
an
important
part
in
the
study
of
prehistoric
societies.
C．Zhoukoudian
is
a
World
Heritage
Site.
D．Zhoukoudian
is
in
great
need
of
protection.
答案：D
解析：段落大意题。本段在开头叙述完周口店对于考古的意义之后详细叙述周口店现在所处的糟糕状况，因此D项才是该段的大意。
4．From
the
passage,
we
can
infer
that
________.
A．the
work
of
excavating
the
Beijing
Man
Site
has
not
proceeded
smoothly
B．Beijing
Man
had
a
short
life
C．Beijing
Man
lived
in
the
caves
of
Longgushan
D．archaeologists
found
six
complete
skulls
and
more
than
150
teeth
in
1929
答案：A
解析：推理判断题。根据第三段的最后两句：对“北京人”遗址的发掘工作由于日本的侵略曾一度中止，新中国成立后，发掘工作又重新开始。由此可以推知对“北京人”遗址的发掘工作进展得不顺利。故选A。
Ⅱ.读后续写
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。续写的词数应为150左右。
Tawny
Nelson
is
a
single
mother
of
four
sweet
little
girls
aged
nine,
five,
two,
and
one
year
old.
It's
not
easy
to
take
care
of
the
girls
all
on
her
own.
Recently,
she
shared
a
story
with
Frank
Somerville,
a
news
anchor
for
KTVU
News
in
California.
He
was
so
moved
by
her
story
that
he
shared
it
on
his
Facebook
page.
Tawny's
story
opened
with
her
visiting
the
grocery
store.
It
was
a
rainy
and
miserable
day
and
by
the
time
she
got
all
the
girls
loaded
in
the
truck
and
ready
to
head
home,
it
was
dark
and
pouring
down.
When
she
tried
to
start
her
truck,
it
wouldn't
start.
With
no
one
to
call,
Tawny
turned
to
ask
strangers
for
help
to
charge
her
truck.
Hours
passed
and
so
did
at
least
twenty
people.
They
all
ignored
her.
Tired
and
hungry,
her
daughters
began
to
act
out.
Tawny
was
filled
with
tears
when
someone
knocked
on
her
passenger
window.
Somerville
writes,
“I
swear
I
got
chills
when
I
read
what
happened
next.”
And
you
will
do
the
same
when
you
read
Tawny's
story：
I
am
the
single
mother
of
four
absolutely
beautiful
little
girls.
They
are
nine,
five,
two,
and
one
year
old.
And
things
have
been
particularly
rough
since
my
ex
left.
Our
truck
had
a
flat
tire
and
I
had
to
inflate
it
constantly.
The
driver
side
window
motor
died.
And
I
needed
a
new
belt.
The
truck
was
a
mess.
And
we
didn't
drive
anywhere
unless
we
had
to.
Well,
the
other
day
we
desperately
needed
to
go
to
the
store.
So
we
loaded
up
and
drove
to
the
Winn
Dixie
about
9
blocks
away.
When
we
got
out
of
the
store
it
was
far
after
dark.
And
it
was
raining
heavily.
I
loaded
my
kids
and
groceries
into
the
truck.
答案
Paragraph
1:
My
battery
was
dead.
My
phone
broke
down.
I
had
no
family
to
chat
with
and
I
had
to
do
everything
on
my
own.
I
turned
to
more
than
twenty
people
for
help
but
they
all
turned
me
down.
My
five?year?old
girl
was
very
hungry
and
began
to
cry.
My
two?year?old
daughter
wanted
to
go
home
and
my
oldest
girl
tried
to
help.
I
felt
that
I
was
the
worst
mother
ever.
Paragraph
2：
I
was
crying
when
a
gentleman
stopped
and
offered
to
help
me.
He
handed
me
a
plate
of
chicken
and
biscuits
and
bottles
of
water.
He
said,
“Feed
your
girls.
I
have
a
truck
on
the
way
and
my
wife
will
be
here
to
take
you
home.”
What
he
said
was
right.
His
wife
arrived
followed
by
their
truck.
We
and
the
truck
were
taken
home.
The
next
morning
the
gentleman
returned
to
my
house
with
a
man
who
replaced
my
battery
and
fixed
my
window.
Seeing
the
scene
I
burst
into
tears.Unit

if填空。
1．If_only
the
explosion
had
not
happened!
2．I'll
go
there
only_if
he
is
invited
to.
解析：在only
if这个短语中，副词only是中心词，而从属连接词if则只是用来连接从句的，因此，它表示“只有……(才)；只有在……的时候，唯一的条件是……”的意思。
if
only常常用来表达强烈的愿望或遗憾，因此，主要用在虚拟语气中，用以表达强烈的愿望或非真实条件。常被译为“但愿；要是……该多好啊”等。
B．用quicken,
accelerate,
hasten,
hurry,
rush或speed的适当形式填空。
3．The

that
his

others.
解析：quicken,
accelerate,
hasten,
hurry,
rush,
speed这些动词均含“加快，使加快”之意。
quicken为普通用词，指增加速度、速率。
accelerate着重指频率或速度运转加快。
hasten指由于事情的紧迫性或突然性而加速。
hurry指赶紧或匆忙地做某事或催促别人做某事，隐含草率或混乱的意思。
rush含义与hurry相近，但rush显得更仓促更慌乱。
speed侧重实际的快速行动，常用词组是speed
up。
C．用divide,
separate或part的适当形式填空。
9．Divide
the
candies

the
children,
please.
10．I
remember
the
way
we
parted.
11．England
is
separated
from
France
by
the
English
Channel.
解析：divide,
separate,
part这些动词都有“分开”之意。
divide指把一个整体按要求分成几个部分，暗示分配之意；也可指分开两个对立的事物。
separate指把两个人或物分开，着重从原属一个整体中移出一部分或把两者隔开。
part多指使紧密相连的人或物分开，往往暗示最后分离的意味。
D．用skillful或skilled填空。
12．We

many
skilled
seamen
on
our
ship,

help
us.
13．They

Ⅰ.阅读理解
“Around
500,000
years
ago,
at
the
Peking
Man
Site
at
Zhoukoudian
in
Beijing's
suburban
Fangshan
district,
which
is
about
50km
from
the
city
of
Beijing,
there
lived
early
human
beings，”
says
a
Chinese
history
textbook.
The
textbook
now
has
to
be
revised.
New
dating
techniques
suggest
the
remains
of
Peking
Man—found
in
the
1920s—are
over
200,000
years
older
than
previously
thought.
What's
important
about
that
date,
about
770,000
years
ago,
is
that
this
was
an
ice
age
on
Earth.
Over
Earth's
long
history,
there
have
been
a
number
of
times
when
ice
and
snow
covered
a
large
part
of
its
surface.
Such
periods
are
known
as
ice
ages.
Earth
is
in
an
ice
age
now.
It
started
about
2
million
years
ago.
Despite
the
many
warm
periods
since
then,
scientists
regard
the
whole
time
as
one
ice
age
because
of
the
continuous
existence
of
at
least
one
large
ice
sheet—the
one
over
Antarctica.
The
new
discovery
was
made
by
Chinese
and
USA
scientists.
It
suggests
Peking
Man
is
probably
our
oldest
cold
weather
human
being,
said
Darryl
Granger,
an
atmospheric
scientist
at
Purdue
University
whose
research
appears
in
Thursday's
edition
of
the
journal
Nature.
The
average
yearly
temperature
at
the
time
in
that
part
of
China
was
around
the
freezing
mark,
but
it
was
too
dry
for
an
ice
sheet,
Granger
said.
This
raises
a
question.
How
did
Peking
Man
survive
the
cold
weather?
Rick
Potts,
a
Smithsonian
Institution
human
origins
expert
who
wasn't
involved
in
the
research,
raised
three
possibilities：
First,
fire.
Early
findings
showed
signs
of
a
fire
in
Peking
Man's
cave.
But
there
has
been
debate
about
whether
the
fire
was
accidental
or
controlled.
Second,
fur.
There
is
no
evidence
that
Peking
Man
used
simple
tools
to
make
more
form?fitting
clothes.
It's
more
likely
he
wore
animal
fur.
Last,
he
may
have
developed
gradually
to
handle
the
cold.
Peking
Man
may
have
experienced
physiological
changes
that
allowed
more
blood
to
flow
to
his
hands
and
legs,
Potts
said.
“People
in
general
who
live
in
colder
climates
tend
to
be
shorter
and
wider，”
he
explained.
Unlike
the
times
of
Peking
Man,
today
the
global
temperature
is
rising
due
to
the
greenhouse
effect.
In
the
future,
could
humans
develop
to
handle
the
warmth
just
as
Peking
Man
did
to
fight
the
cold?
本文主要讲的是一项最新的研究发现，周口店“北京人”比我们以前估计的要早二十多万年。
1．According
to
the
new
research,
Peking
Man
actually
dates
back
to
________.
A．around
500,000
years
ago
B．over
200,000
years
ago
C．about
770,000
years
ago
D．about
2
million
years
ago
答案：C
解析：细节理解题。由第二段最后一句话“What's
important
about
that
date,
about
770,000
years
ago,
is
that
this
was
an
ice
age
on
Earth.”可知。
2．What
is
the
most
important
standard
for
scientists
to
decide
an
ice
age?
A．The
weather
conditions.
B．The
continuous
existence
of
any
large
ice
sheets.
C．The
average
yearly
temperature.
D．The
long
period
of
snowfall.
答案：B
解析：推理判断题。由第四段第三句话“...scientists
regard
the
whole
time
as
one
ice
age
because
of
the
continuous
existence
of
at
least
one
large
ice
sheet—the
one
over
Antarctica.”可知。
3．Which
of
the
following
is
TRUE
of
Peking
Man?
A．He
is
the
oldest
human
being.
B．He
used
fire
to
keep
warm.
C．He
wore
form?fitting
clothes
made
from
fur
with
simple
tools.
D．He
might
have
been
shorter
and
wider
than
previously
thought.
答案：D
解析：细节理解题。由倒数第二段中的“People
in
general
who
live
in
colder
climates
tend
to
be
shorter
and
wider”可推知，北京人可能比我们原先预计的要矮胖，这样才能与当时的气候相适应。
4．What
does
the
passage
mainly
want
to
convey
to
us?
A．The
latest
discovery
about
Peking
Man.
B．The
life
of
Peking
Man
during
the
ice
age.
C．The
way
Peking
Man
use
to
fight
against
coldness.
D．The
time
Peking
Man
dates
from.
答案：A
解析：主旨大意题。本文是报道类文章，第二段即点明了本文的中心——“北京人”的年代应该是处于冰河世纪，比我们原先的估计早二十多万年。
Ⅱ.七选五
It
is
important
to
introduce
yourself
in
a
creative,
memorable
way
to
distinguish
yourself
from
the
crowd.
__1__
Since
being
witty
(言辞诙谐的)
doesn't
always
come
easily,
try
one
of
these
creative
introductions
and
separate
yourself
from
the
rest.
Write
your
first
or
last
name
on
a
piece
of
paper.
__2__
So
if
your
name
is
Tom,
you
might
say
you
are
tireless,
optimistic
and
mild.
__3__
Then
say
that
you
will
do
so
in
the
words
of
your
“best
and
worst
critic”—your
mother.
By
breaking
the
ice
in
this
way,
you
can
go
on
in
either
a
humorous
or
serious
fashion.
Introduce
yourself
silently,
by
drawing
a
picture
of
yourself
on
a
large
sheet
of
paper.
__4__
In
fact,
in
some
groups,
it
may
be
better
if
you
don't.
Put
a
title
at
the
top
of
your
drawing,
if
you
like,
such
as,
“Hello!
This
is
me.”
Turn
the
traditional
introduction
upside
down
by
describing
yourself
in
exactly
opposite
terms
of
who
you
are.
Have
fun
with
this
“back
door
approach”，
and
keep
people
guessing
just
how
much
you
are
exaggerating
(夸张).
__5__
Don't
bother
calling
me
tomorrow,
because
I
will
be
hiding
in
a
closet.
Send
text
messages
to
my
girlfriend
while
I
drink
a
Bud
Light
on
the
job.
A．This
introduction
requires
you
to
be
gifted
in
art.
B．Freely
admit
that
you
don't
like
talking
about
yourself.
C．It
makes
no
difference
whether
you
possess
artistic
abilities.
D．For
example：I
am
probably
the
laziest
person
you
will
ever
meet.
E．Use
each
letter
as
the
first
letter
in
an
adjective
that
describes
you.
D．Bring
in
the
surprise
factor—sometimes
known
as
the
shock
factor.
G．After
all,
anybody
can
stand
up
and
announce
their
name,
business
title
and
job
responsibilities.
本文是一篇说明文，介绍了几种比较有创意的自我介绍的方式。
1．G 解析：由上文“用一种有创意的，让人记住的方法介绍你自己，使得你自己从人群中脱颖而出很重要”可知，下文具体说明这样做的原因，故G符合语境。
2．E 解析：由下文所举的例子“So
if
your
name
is
Tom,
you
might
say
you
are
tireless,
optimistic
and
mild”可知E符合语境。
3．B 解析：由下文暗示“Then
say
that
you
will
do
so
in
the
words
of
your
‘best
and
worst
critic’”“By
breaking
the
ice
in
this
way”可知B项符合语境。此处表示大方地承认你不喜欢谈论自己，然后说你会用妈妈对你所做的最好和最坏的评论谈论自己。
4．C 解析：由上文信息“drawing
a
picture
of
yourself”可知此处涉及绘画方面的内容，故C“你是否有艺术才能不重要”符合语境。
5．D 解析：上文提到“describing
yourself
in
exactly
opposite
terms
of
who
you
are”可知，下文具体举例说明了这种介绍方式，故D符合语境。
