UNIT 5 Into the unknown
Ⅰ.阅读理解
（2025·漳州模拟）A starfish has five identical arms with a layer of “tube feet” beneath them. Have you ever wondered whether starfish have defined front and back ends — and if they have no heads at all？ The answer suggests new genetic （基因的） research is the opposite. “It’s as if the starfish is completely missing a trunk，” said Laurent Formery at Stanford University. “And it’s best described as just a head crawling along the seafloor.”
Starfish belong to echinoderms with lines of symmetry （对称） radiating out from a center point， like spokes on a wheel. So the unusual animals have unique body plans（结构）arranged in five equal sections that greatly differ from the bodies of bilateral animals， which have left and right sides mirroring each other.
Starfish begin as fertilized eggs that hatch and become larvae （幼虫） that float in the ocean for weeks to months before settling on the ocean floor. There， they go through a process that transforms a bilateral body into a star shape. “This has been a mystery for centuries，” said Christopher Lowe at Stanford University.
Researchers used new methods of genetic sequencing to create an unprecedented 3D map to determine where genes were expressed as starfish developed and grew. They found that genetic features associated with the development of a head were detected all-over the starfish especially concentrated in the center of the star and the center of each “arm”. Meanwhile， gene expression for trunk sections was largely absent. “This suggested that starfish have the most dramatic example of decoupling of the head and the trunk regions that we are aware of today，” said Formery.
Studying groups like echinoderms could solve some of the most complex mysteries about the evolution of life on Earth. “People are generally not drawn to these animals， and yet they probably represent how much of life got started，” Lowe said. Understanding how animals like starfish have developed could also allow insights into the varied ways that different species remain healthy. Daniel Rokhsar at the University of California said，“If we explore unusual animals that are operating in unusual ways， that means we are broadening our perspective of biology. This is eventually going to help us solve both ecological and biomedical problems.”
1.In what aspect are starfish different？（ ）
A.They have no trunks at all. B.They have left and right sides.
C.They have a star shape from birth. D.They have unequally stretching arms.
2.How did researchers explore the mystery of starfish？（ ）
A.By creating a seabed map. B.By comparing body plans.
C.By locating their gene expressions. D.By tracking their development and growth.
3.What does the underlined word “decoupling” in Paragraph 4 mean？（ ）

C.Exchanging. D.Expanding.
4.Why do scientists study unusual animals？（ ）
A.To reveal the origin of life. B.To improve health of diverse species.

Ⅱ.阅读七选五
（2025·云南模拟）An increasing number of researches indicate that warming temperatures are causing more deaths in creatures ranging from birds in Mojave Desert to bumblebees in North America. Researchers warn that heat stress could become a major factor in future extinctions of wildlife. 5.（ ） It is essential to have plenty of water for wildlife to drink and bathe in. Hot weather can be great for some creatures. 6.（ ） A shallow dish of water will benefit a wide range of wildlife. If you want to do more， you can create a tiny pond. It’s possible to make a simple one out of an old washing-up bowl.
You can also help animals by offering them somewhere cool to take a break. 7.（ ） Heatwaves are not the time to tidy your garden either — leave some plants uncut. They’ll provide shelter and food if they’ve gone to seed.
Food is also crucial. You can grow plants that can continuously supply quality food sources. 8.（ ） Be sure what you are giving is high-quality and digestible. Keep food dry and clean any feeders that animals come in direct contact with to decrease possible illnesses.
9.（ ） Compared with plants， concrete surfaces absorb more heat in the day — about more than 20℃ hotter than grass. So why don’t you replace those surfaces with plants？ Besides， in the shade of trees， surface temperatures can be reduced by around 10℃， so planting a tree in your garden will cool both you and wildlife down.
A.Reducing the heat can be another effective way.
B.Artificial feeding with feeders can also be a great idea.
C.Luckily， you can extend a helping hand with some easy steps.
D.A pile of wood in a shady corner will offer places for insects to hide.
E.How can you make your local area become more friendly to animals？
F.Follow these simple tips to make sure you’re keeping animals properly.
G.But even heat-loving creatures can’t survive unless they can obtain enough water.

Dear fellow students，
With a growing number of tourists during the holidays，the inappropriate behavior is increasing — taking pictures with a “no photo” sign nearby，random graffiti at tourist spots，and littering everywhere， which is having a severe impact on the places of interest.In order to leave a perfect landscape， we have a variety of things to pay attention to.
First of all，tourists should always remind themselves not to do any damage to the spots. Furthermore， the exposure of the bad behavior should be increased. Last but not least，the government should implement some punitive measures by improving relevant laws and regulations.
I believe that these problems will be solved step by step. Let’s band together to make a better future！

Ⅰ.阅读理解
（2025·漳州模拟）A starfish has five identical arms with a layer of
“tube feet” beneath them. Have you ever wondered whether starfish
have defined front and back ends — and if they have no heads at all？ The
answer suggests new genetic （基因的） research is the opposite. “It’s
as if the starfish is completely missing a trunk，” said Laurent Formery
at Stanford University. “And it’s best described as just a head crawling
along the seafloor.”
Starfish belong to echinoderms with lines of symmetry （对称）
radiating out from a center point， like spokes on a wheel. So the unusual
animals have unique body plans（结构）arranged in five equal sections
that greatly differ from the bodies of bilateral animals， which have left
and right sides mirroring each other.
Starfish begin as fertilized eggs that hatch and become larvae （幼
虫） that float in the ocean for weeks to months before settling on the
ocean floor. There， they go through a process that transforms a bilateral
body into a star shape. “This has been a mystery for centuries，” said
Christopher Lowe at Stanford University.
Researchers used new methods of genetic sequencing to create an
unprecedented 3D map to determine where genes were expressed as
starfish developed and grew. They found that genetic features associated
with the development of a head were detected all-over the starfish
especially concentrated in the center of the star and the center of each
“arm”. Meanwhile， gene expression for trunk sections was largely
absent. “This suggested that starfish have the most dramatic example
ofdecoupling of the head and the trunk regions that we are aware of
today，” said Formery.
Studying groups like echinoderms could solve some of the most
complex mysteries about the evolution of life on Earth. “People are
generally not drawn to these animals， and yet they probably represent
how much of life got started，” Lowe said. Understanding how animals
like starfish have developed could also allow insights into the varied ways
that different species remain healthy. Daniel Rokhsar at the University of
California said，“If we explore unusual animals that are operating in
unusual ways， that means we are broadening our perspective of biology.
This is eventually going to help us solve both ecological and biomedical
problems.”

（2025·云南模拟）An increasing number of researches indicate
that warming temperatures are causing more deaths in creatures ranging
from birds in Mojave Desert to bumblebees in North America.
Researchers warn that heat stress could become a major factor in future
extinctions of wildlife. 5.（ ）
It is essential to have plenty of water for wildlife to drink and bathe
in. Hot weather can be great for some creatures. 6.（ ） A shallow
dish of water will benefit a wide range of wildlife. If you want to do
more， you can create a tiny pond. It’s possible to make a simple one
out of an old washing-up bowl.
You can also help animals by offering them somewhere cool to take a
break. 7.（ ） Heatwaves are not the time to tidy your garden
either — leave some plants uncut. They’ll provide shelter and food if
they’ve gone to seed.
Food is also crucial. You can grow plants that can continuously
supply quality food sources. 8.（ ） Be sure what you are giving is
high-quality and digestible. Keep food dry and clean any feeders that
animals come in direct contact with to decrease possible illnesses.
9. （ ） Compared with plants， concrete surfaces absorb more
heat in the day — about more than 20℃ hotter than grass. So why don’t
you replace those surfaces with plants？ Besides， in the shade of trees，
surface temperatures can be reduced by around 10℃， so planting a tree in
your garden will cool both you and wildlife down.
A. Reducing the heat can be another effective way.
B. Artificial feeding with feeders can also be a great idea.
C. Luckily， you can extend a helping hand with some easy steps.
D. A pile of wood in a shady corner will offer places for insects to hide.
E. How can you make your local area become more friendly to animals？
F. Follow these simple tips to make sure you’re keeping animals
properly.
G. But even heat-loving creatures can’t survive unless they can obtain
enough water.

语篇解读：本文是一篇说明文。文章主要介绍了旅游景点——
敦煌。
25. in 考查介词。be interested in意为“对……感兴趣”，为固定搭
配，故填介词in。句意：那些对敦煌灿烂的历史感兴趣的人将被该城
市的主要景点之一的敦煌莫高窟所吸引。
26. is blocked 考查动词的时态、语态和主谓一致。空处所在句为主
从复合句，which引导定语从句，主句缺少谓语动词；此处描述客观
情况，应用一般现在时；主语The entrance与block之间是被动关系，
应用被动语态；且主语是第三人称单数。故填is blocked。句意：每个
洞窟的入口都被一扇锁着的门堵着，只有专业导游才能打开。
27. sizes 考查名词复数。根据from very small to absolutely huge可
知，此处应用名词复数，表示不止一个尺寸，故填sizes。
28. attention 考查名词。空前有much修饰，应该用不可数名词作
drew的宾语。draw attention to表示“吸引对……的注意力”，故填
attention。
29. To catch 考查非谓语动词。结合句意可知，此处作目的状语，应
用动词不定式，注意句首首字母要大写，故填To catch。句意：为了
捕捉到这一令人难以置信的景色，你必须早起。
30. truly 考查副词。此处表示“描绘出一幅真正古色古香的景
象”；空后picturesque是形容词，应用副词修饰，故填truly。
31. and 考查连词。本句是祈使句，get off和walk up两个动词短语并
列且表顺承，故填and。句意：从骆驼上下来，爬上一个俯瞰月牙泉
的相当陡峭的沙丘。
32. regarded 考查非谓语动词。分析句子结构可知，此处为非谓语动
词短语作定语，修饰position，且“位置”是“被认为”，应用过去分
词regarded。句意：从这个被认为是最佳位置的地方看，令人难以置
信的日落令人惊叹。
33. where 考查定语从句。分析句子结构可知，该空引导定语从句修
饰先行词Dunhuang Museum，且指代先行词在定语从句中作地点状
语，故填关系副词where。句意：没有参观敦煌博物馆的敦煌之旅是
不完整的，在那里可以将这座城市的所有历史遗迹置于恰当的历史背
景中。
34. containing 考查非谓语动词。分析句子结构可知，空处为非谓语
动词短语作状语。contain意为“包含”，和主语The museum构成逻辑
上的主谓关系，应用动词-ing形式。故填containing。句意：博物馆很
大，收藏了许多原作艺术品。
Ⅴ.应用文写作
（2025·贵阳适应性考试）当下，正值踏青赏花好时节，贵州各
地迎来了大量游客，然而旅游中不文明行为时有发生。假定你是校英
文报主编李华，请你为校英文报写一篇倡议书，呼吁大家文明出游，
内容包括：
（1）不文明出游的现象；
（2）对文明出游发出倡议。
注意：（1）写作词数应为80个左右；
（2）可以适当增加细节，以使行文连贯。
参考范文：
Dear fellow students，
With a growing number of tourists during the holidays，the
inappropriate behavior is increasing — taking pictures with a “no
photo” sign nearby，random graffiti at tourist spots，and littering
everywhere， which is having a severe impact on the places of interest.In
order to leave a perfect landscape， we have a variety of things to pay
attention to.
First of all，tourists should always remind themselves not to do any
damage to the spots. Furthermore， the exposure of the bad behavior
should be increased. Last but not least，the government should implement
some punitive measures by improving relevant laws and regulations.
I believe that these problems will be solved step by step. Let’s band
together to make a better future！
