14
days．That's
the
ti
(?http:?/??/?www.21cnjy.com?)me
Chinese
scientists
took
to
identify
the
full
genetic
sequence
of
the
novel
coronavirus
（新冠病毒）
since
its
outbreak．It
was
shared
with
the
WHO
immediately,
and
has
now
become
an
important
foundation
for
global
researchers
in
the
fight
against
the
COVID﹣19．But
first,
let
us
turn
the
clock
back
17
years,
when
it
took
months
to
identify
the
SARS
virus．From
months
to
14
days,
what
changed？
It
turns
out
AI
played
an
important
part．2-1-c-n-j-y
The

fir

obtained
bronchoalveolar
lavage（BAL）
fluid（支气管扩张灌洗液）samples
from
patients,
isolated（分离）
the
DNA
and
RNA,
then
sequenced
the
genetic
material
by
comparing
them．AI's
advantage
is
its
ability
to
recognize
patterns
among
a
flood
of
data．21
cnjy
com
Let
me
put
it
in
a
(?http:?/??/?www.21cnjy.com?)
simple
way．Sequencing
the
coronavirus
genome（基因组）
is
similar
to
looking
for
a
needle
in
a
haystack（干草堆）﹣﹣﹣looking
for
genotypes（基因型）
with
specific
characteristics
from
a
huge
gene
pool．That's
where
search
algorithm（算法）,
a
branch
of
modern
AI,
comes
in．Think
of
it
as
an
efficient
search
engine,
which
can
find
the
needle
in
the
haystack．This
search
algorithm
can
shorten
months﹣long
genetic
sequencing
to
weeks
or
even
just
a
few
days．Combined
with
macro﹣genomic
sequencing
and
a
virus
library,
this
AI
technology
can
also
be
used
in
tracking
virus
mutation（突变）．
AI
doesn't
(?http:?/??/?www.21cnjy.com?)
just
support
scientists．It
can
also
help
patients
by
improving
the
efficiency
of
diagnosis（诊断）．China
launched
a
Genomics
Service,
which
can
run
multiple
virus
gene
comparisons
and
produce
a
detailed
report
within
60
seconds．This

has
been

When
I
settled
in
Chi
(?http:?/??/?www.21cnjy.com?)cago,
my
new
city
seemed
so
big
and
unfriendly.
Then
I
had
a
1
problem
and
had
to
go
to
hospital
for
a
2
examination.
???
It
seemed
a
small
3
compared
to
the
one
I
was
about
to
face
,but
things
started
to
go
4
right
from
the
beginning.Not
having
a
car

I
9
the

11

After
I
explained
my

her,
she
pointed

me

my
14

(喇叭)
nearby,

friend
17
at
me
to
get
in.
She
had
returned
to
offer
me
a
18
to
the
hospital.

?Such
unexpected

from

was
a

Dear
Mr.

(?http:?/??/?www.21cnjy.com?)thank
you
for
lending
me
the
CD
what
is

amazing

worth

Unfortunately,
I
can't
show
up
at

apartment
and
return
back
it
this
afternoon
as
I
promise
that
day
I
would.
Last
weekend
I
showed
my
grandparent
the
CD
you
lent
me.
But,
I
got
a
sudden
call
and
left
their
house.
I
was
in
so
a
hurry
that
I
completely
forgot
take
the
CD
with
me.
I'm
really
sorry
about
that.
I
promise
to
bring
them
back
this
Sunday
and
give
it
to
you.
I
sincerely
hope
that
you
won't
be
angrily
with
me.21教育网

2．【句意】去国外旅行对这对老夫妇肯定有益，但他们是否会喜欢仍需观察．
答案：B
本题设空处应为系动词remain的表语，
(?http:?/??/?www.21cnjy.com?)句中使用了以it为形式主语的句式，设空之后的从句为真实主语．原句应理解为：Whether
the

_______．
在新近出版的词典里，关于remain的用法中有如下解释：If

something
remains
to
be
seen，you
mean
it
is
not
at
all
certain
what
will
happen．﹣COLLINS
COBUILD

由此可知，remain其后应该跟不定式的被动语态，remain与其余三个选项所给出的非谓语动词形式都没有类似搭配用法，故答案为B．21

about
thre
(?http:?/??/?www.21cnjy.com?)e
years可知，前面的句子应该是表达的现在完成的概念，所以使用现在完成时，可排除A和D，而get为非延续性动词，而此句表达的是结婚的状态，所以使用be
married来表示．可排除B．
故选：C．
5．【句意】我想知道是什么使得他如此兴奋．
答案是D．考查强调句，本句强调句是w
(?http:?/??/?www.21cnjy.com?)onder的宾语从句，所以语序要用陈述语序，又因为被强调部分是疑问词what，所以what要放在宾语从句的句首，所以答案选D．
6．【句意】不要想当然地认为那些在入学考试中得高分的人会证明是最成功的．
答案是D．本题考查短语用法
(?http:?/??/?www.21cnjy.com?)；本题考查短语take
sth．for
granted
把…看着是理所当然的事；该短语常常用take
it
for
granted
that结构，其中it
做形式主语；故答案是D．【来源：21cnj
y.co
m】
7．【句意】明天市长将会陪同一群加拿大商人来到我们市．
答案：C
解析：A：陪伴（名词）；B：合作；C
(?http:?/??/?www.21cnjy.com?)：陪同；D：联想；结交．根据句意"明天市长将会陪同一群加拿大商人来到我们市"及所给选项分析可知，本题答案为C选项；其余选项均不符合题意或用法．
8．【句意】我更愿意Inverness的公寓而不愿意Perth的公寓，因为我想住得离我妈妈的公寓近点．
答案：B
考查指示代词用法．o
(?http:?/??/?www.21cnjy.com?)ne与that虽可用来指代同名异物，但one为泛指，相当于a/an+名词；
that为特指，相当于the+名词．此处应是a
flat，故选B．it指代同类同物；which哪一个；哪一些．
故选：B．
9．【句意】哈里不仅是我的邻居．他也是我的好朋友．
答案：D．考查介词短语．less
than小于；at
least至少；at
most至多；more
than不只是，根据题意，D正确．
故选：D．
10．【句意】经过疲倦的长途旅行之后，当我们最后成功到家后，一步都走不了了．
答案：C．根据句意，mana
(?http:?/??/?www.21cnjy.com?)ged
to
get
home"成功到家"，而A．tried
to尽力，B．succeeded后接in
doing
sth．，D．attempted
to尝试做，故选C．

14
days．That
(?http:?/??/?www.21cnjy.com?)'s
the
time
Chinese
scientists
took
to
identify
the
full
genetic
sequence
of
the

was
shared
with
the
WHO
immediately,
and
has
now
become
an

for
global
researchers
in

what
changed？
It

out
AI

Let
me
put
it
(?http:?/??/?www.21cnjy.com?)in
a

of
modern

of
it
as
an

the
needle
in

【分析】本文是说明文．文章介绍了人工智能在识别和快速诊断新冠状病毒方面所起的作用．
【解答】（1）C．细节理解题．文章
(?http:?/??/?www.21cnjy.com?)第二段中提到"AI's
advantage
is
its
ability
to
recognize

in．（冠状病毒基因组的测序类似于海里捞针﹣﹣从一个庞大的基因库寻找具有特定特征的基因图谱．这就是现代人工智能的一个分支﹣﹣搜索算法的用武之地）"．由此可知，搜索算法可以从一个庞大的基因库寻找具有特定特征的基因图谱．搜素算法是人工智能的一个分支,
也就是说人工智能能够从大量的数据库中迅速识别基因图谱．故选C．
（2）B．细节理解题．根据第三
(?http:?/??/?www.21cnjy.com?)段中"Think

When

【解析】本文是一篇记叙文，作者讲述了初到人
(?http:?/??/?www.21cnjy.com?)生地不熟的城市，遇到难处，最终得到了陌生人的帮助。
（1）考查形容词。从下文“要去医院”来看，应该是生理上出了问题。故选A。
（2）考查形容词。因为生病了，所以要去医院做个彻底全面的检查。D合语境。
（3）考查名词。下文中的“face”的逻辑宾语是“the
one”，“the
one”指代的那个词就是本题的答案。从下文看应该是“challenge”。比起我即将面临的挑战，这似乎算不什么挑战。选B。
（4）考查固定搭配。从下文“没有车，也不......”来看，应该是从一开始事情就不妙，即出了问题。Everything
goes
wrong.选A。
（5）考查动词。leaving“离开”；visiting“参观”；knowing“了解”；appreciating“欣赏”。句意：没有一个车了解这个城市，所以选C。
（6）考查连词。根据下文“I
was
going
to
be
late”可知是转折关系，句意：尽管我离开有充足的时间。所以选A。
（7）考查形容词。It
be
clear
that...，固定句型“...…很明显”，句意：很明显我快要迟到了，所以选C。
（8）考查形容词。句意：尽管我给自己留了足够的时间，但眼看就要迟到了，因为我上错了车，汽车载着我向相反的方向开去。选D。
（9）考查动词短语。句意：我下了车，站在人行道上不知如何是好。C合语境。
（10）考查名词。我初来乍到，在陌生的城市，我放眼望去的当然是陌生人。选C。
（11）考查副词。根据下文“
instead
of
moving
on”
得知，陌生人停下来搭理我
出乎我的意料，使我感到惊讶。选B。
（12）考查形容词根据下文“After
I
explained
my…”可知问我是否可以，句子意思“她停下来问我是否可以”，所以选C。
（13）考查名词。idea“主意”；motivation“动机”；excuse“借口”；situation“情况”。句意：我向她解释了我的情况后。所以选D
（14）考查名词。appointment“职位”；apartment“公寓楼”；direction“方向”；station意思“站”。句意：那里的公交车将把你带回到原来的站点。所以选D。
（15）考查形容词。根据下文“that
someone
had
been
willing
to
help.”可以知道作者很感激，所以选B。
（16）考查副词。根据下文“hearing
a
horn
(喇叭)
nearby,”可知句意：这时，听到附近的喇叭声。所以选B。
（17）考查动词。wave
at

Dear
Mr.
(?http:?/??/?www.21cnjy.com?)
Green,
thank
you
for
lending
me
the
CD
what
is
really
amazing
and
worth
listened
to.
Unfortunately,
I
can't
show
up
at
your
apartment
and
return
back
it
this
afternoon
as
I
promise
that
day
I
would.
Last
weekend
I
showed
my
grandparent
the
CD
you
lent
me.
But,
I
got
a
sudden
call
and
left
their
house.
I
was
in
so
a
hurry
that
I
completely
forgot
take
the
CD
with
me.
I'm
really
sorry
about
that.
I
promise
to
bring
them
back
this
Sunday
and
give
it
to
you.
I
sincerely
hope
that
you
won't
be
angrily
with
me.21·cn·jy·com
【答案】

→promised。⑤grandparent
→grandparents。⑥But

→angry。
21·世纪
教育网
【解析】本文是一篇应用文。作者对不能按
(?http:?/??/?www.21cnjy.com?)时还CD跟格林先生表示歉意的信息。
①考查定语从句。先行词为CD，指物，在定语从句中做主语，故用关系代词which或that，因此what改为that/which。
②考查非谓语动词。be
worth
doing
固定短语，“值得做某事”，故listened改为listening。
③考查介词。return表示“归还”的意思，是及物动词，后面不需要介词，故去掉back。
④考查时态。按照我以前答应的would提示用一般过去时，故promise改为promised。
⑤考查名词。句意：上周末我把从你那借的CD给我的祖父母们听。grandparents是复数名词，故grandparent改为grandparents。
⑥考查连词。分析句子可知，前后表示转折，但是but后面没有逗号。故But改为However。
⑦考查副词。句意：我如此匆忙以至于忘了拿上CD。“如此……以至于”可以用so+形容词+冠词+名词或such+冠词+形容词+名词，本句使用such加冠词加名词结构。故so改为such。
⑧考查非谓语动词。forget
to
do固定短语，“忘记去做某事”，故forget后面加上to。
⑨考查代词。根据其前的CD可知，此处应用代词单数形式作宾语，故将them改为it。
⑩考查形容词。根据be动词后用形容词，故angrily改为angry。
