Ⅳ.阅读理解
A
Saturn's icy moon Enceladus could
theoretically be home to methane?producing
(产甲烷的) alien life, NASA said. Researchers made
the announcement based on data
from 2015, when the spacecraft Cassini
detected the presence of hydrogen during a
flight through a cloud of gas and ice erupting
from Enceladus' south pole. The
hydrogen could
be a sign of methanogenesis, a form of breath in
which microbes (微
生物) produce methane.
This
is a very significant finding because the hydrogen
could be a potential source of chemical energy
for any microbes
that might be in Enceladus'
ocean，” Linda Spilker, a
scientist at NASA's
Jet Propulsion Labor?atory, said at a
press
conference. “We now know that Enceladus has almost
all
of the ingredients you would need to
support life as we know
it on Earth.” The
findings were published in the journal
Science
.
“This is the closest we've
come, so far, to identifying a place with some of
the ingredients needed for a habitable
environment，” Thomas Zurbuchen, associate
administrator for NASA's Science Mission
Directorate, said in a statement. “These
results demonstrate the nature of NASA's
science missions that are getting us closer
to
answering whether we are indeed alone or not.”
NASA also announced that the Hubble Space
Telescope observed what may have been
water
vapor emerging from the surface of Jupiter's moon
Europa in 2014, and again
around the same area
in 2016.
Confirming the existence of Europa's
gas would allow researchers to study that
moon's chemical makeup without having to dig
through miles of icy crust (表面). The
Cassini
and Hubble discoveries related to these “ocean
worlds” will help
scientists plan NASA's
Europa Clipper mission, set to launch in the
2020s. The plan
is for the unmanned spacecraft
to orbit Jupiter and perform a detailed
investigation
of Europa.
“These
discoveries are coming just at the perfect time，”
Jim Green, director
of NASA's Planetary
Science Division, said. “It enables us to make the
right set
of observations that can tell us
much more about these ocean worlds, Europa in
particular.”

1．The
new discovery made the scientists feel more
________.
A．confident B．doubtful
C．worried D．confused
解析：选A
细节理解题。由第二段中的“This is a very significant
finding”，
第三段中的“This is the closest we've
come”及最后一段中的“These discoveries are
coming just
at the perfect
time”可知，新的发现让科学家们对探测外星生命的任务更
加有信心。
2．According to the text, NASA's science
missions aim to ________.
A．make space travel
a reality
B．analyze Jupiter's chemical makeup
C．find out whether life exists outside Earth
D．explore the resources on Saturn's icy moon
解析：选C 细节理解题。由第三段中的“These results demonstrate
the nature of
NASA's science missions that are
getting us closer to answering whether we are
indeed
alone or
not”可知，NASA科学任务的本质是弄清是否只有地球上存在生命。
3．Which
would be a suitable title for the text?
A．There is life outside Earth
B．Enceladus
could harbor alien life
C．A new study about
Saturn begins
D．NASA is planning a landing on
Jupiter
解析：选B 标题归纳题。本文重点在于告诉我们最近发现
土卫二南极有氢气，这个迹
象可能是外星生命存在的证明。故B项最适合作文章标题。
B
The oddness of life in space never quite goes
away. Here are some examples.
First consider
something as simple as sleep. Its position
presents its own
challenges. The main question
is whether you want your arms inside or outside
the
sleeping bag. If you leave your arms out,
they float free in zero gravity, often
giving
a sleeping astronaut the look of a funny ballet
(芭蕾) dancer. “I'm an inside
guy，” Mike Hopkins
says, who returned from a six?month tour on the
International
Space Station. “I like to be
wrapped up.”
On the station, the ordinary
becomes strange. The exercise bike for the
American
astronauts has no handlebars. It also
has no seat. With no gravity, it's just as
easy to pedal violently. You can watch a movie
while you pedal by floating a
microcomputer
anywhere you want. But station residents have to
be careful about
staying in one place too
long. Without gravity to help circulate air, the
carbon?dioxide you exhale (呼气) has a tendency
to form an invisible (隐形的) cloud
around your
head. You can end up with what astronauts call a
carbon?dioxide headache.
Leroy Chiao, 54, an
American retired astronaut after four flights,
describes
what happens even before you float
out of your seat. “Your inner ear thinks you're
falling. Meanwhile your eyes are telling you
you're standing straight. That can be
annoying
— that's why some people feel sick.” Within a
couple of days — truly
terrible days for some
— astronauts' brains learn to ignore the panicky
signals
from the inner ear, and space sickness
disappears.
Space travel can be so delightful
but at the same time invisibly dangerous. For
instance, astronauts lose bone mass. That's
why exercise is considered so vital that
National Aeronautics and Space Administration
(NASA) puts it right on the workday
schedule.
The focus on fitness is as much about science and
the future as it is about
keeping any
individual astronaut healthy. NASA is worried
about two things: recovery
time once
astronauts return home, and, more importantly, how
to maintain strength
and fitness for the two
and a half years or more that it would take to
make a round?trip
to Mars.
语篇解读：本文是一篇说明文。在
太空中的生活有多神秘？这可能是你想象不到的。本
文从不同角度介绍了在太空中生活时你要面对的各种
挑战。
4．What is the major challenge to
astronauts when they sleep in space?
A．Deciding on a proper sleep position.
B．Choosing a comfortable sleeping bag.
C．Seeking a way to fall asleep quickly.
D．Finding a right time to go to sleep.
解析：选A 细节理解题。根据第二段第二句“Its position presents its
own
challenges.”可知合适的睡觉姿势对于太空中的宇航员是主要的挑战。
5．The astronauts will suffer from a
carbon?dioxide headache when ________.
A．they
circle around on their bikes
B．they use
microcomputers without a stop
C．they exercise
in one place for a long time
D．they watch a
movie while pedaling
解析：选C
细节理解题。根据文章第三段最后三句可知在一个地方时间太长就会引起
头疼。
6．Some
astronauts feel sick on the station during the
first few days because
________.
A．their
senses stop working
B．they have to stand up
straight
C．they float out of their
seats unexpectedly
D．their brains receive
contradictory messages
解析：选D 推理判断题。根据第四段的“Your
inner ear thinks you're falling.
Meanwhile
your eyes are telling you you're standing
straight. That can be annoying
— that's why
some people feel
sick.”可以推知由于他们的大脑接受到相反的信息而引
起了他们的恶心。
7．One
of NASA's major concerns about astronauts is
________.
A．how much exercise they do on the
station
B．how they can remain healthy for long
in space
C．whether they can recover after
returning home
D．whether they are able to go
back to the station
解析：选B
细节理解题。根据文章最后一句可知NASA关心他们如何在太空中长时间
保持健康。

of wine — it was based
on the fact that they were told it was good wine.

E．In fact,
there is no universally agreed theory for why we
actually yawn.
F．Maybe you'd refer to the move
of the Earth or something comparably huge.

语篇解读：本文是说明文。文章列举了五件让人琢磨不透的简单事。
1．解析：选D
根据本段标题可知，本段是介绍“关于1＋1＝2的论证有300多页”。
D项中的one plus
one equals two 符合本段内容。
2．解析：选G
根据本空后的例子可知，同样是在说生病，但是有的时候用 the，有
的时候不用 the，所以说
the“这个词实际上非常奇怪”，只是因为它太常见了，所以“大
部分人从来没想过这回事”。
3．解析：选E 本空前两句分别介绍了关于打哈欠的两种不同理论，由此可推测“实
际上，关
于我们为什么打哈欠现在还没有一个一致同意的理论”。本空后一句中的 no one
knows
that either 也提示了大家还不知道为什么会打哈欠、打哈欠为什么会传染。
4．解析：选C 根据本空前的内容可知，我们有时会以自己与某一地标性建筑的相对
位置来定
义左右，“但是如果我们是与一个盲人交谈呢”，又该如何定义左右呢？这也是为
什么如何定义左右困扰
了哲学家很多年。
5．解析：选B 根据本段列举的例子及最后一句“Their
enjoyment of the product
wasn't based on
appreciation of wine － it was based on the fact
that they were told
it was good
wine”可知，“我们喜欢一样东西不是因为它能带给我们愉悦，而是因为其他
的原因”。
