第一节(共 15 小题;每小题 2.5 分,满分 37.5 分)
阅读下列短文,从每题所给的 A 、B 、C 、D 四个选项中选出最佳选项。
A
Osedax worms have been found in oceans all over the world. They’ve only ever been
spotted on bones, which makes some scientists think that the bone-eaters are specialized to live in odd ecosystems, such as whale falls. “Those kinds of animals are definitely uniquely adapted to
the environment in which you find them, ”says marine biologist River Dixon. She is a graduate student at the University of Louisiana at Lafayette.
But as recent experiments show, the bone-eaters may not be picky about what type of bones they devour(吞食). Last year, biologists spotted Osedax worms in the Gulf of Mexico for the first time. And not on whale bones. Dixon was part of a research team that made the discovery. In early 2019, her group put the dead bodies of three alligators(短吻鳄)in water about 2 kilometers deep. Over the next few months, they sent a remote-controlled vehicle a few times to spy on what were
试卷第 3 页，共 13 页
essentially “alligator falls”.
51 days after the alligators were placed in the seawater, scientists revisited. “The flesh was gone”, Dixon says. . “It had been reduced to just the skeleton(骨骼).” And just as at whale falls, it hosted a carpet of bone-eating Osedax worms. These worms were similar to other bone-eaters but represented a never-before observed species. That means the scientists who found them get to
name it (although Dixon says they haven’t settled on a name yet).
The lab where Dixon works studies food systems in the deep ocean. Algae and plants use
photosynthesis(光合作用)to turn sunlight into food. Animals eat those plants and algae to survive. Then larger animals may eat those animals. But sunlight doesn’t reach the deep ocean’s bottom.
So other pathways are essential. These pathways include whale falls and other dead bodies. The scientists wondered how alligator falls fit into a larger food web. To find out, they submerged
them.
Studying alligator falls, Dixon says, could help show how life evolved(进化)in the deep sea. It’s possible that the creatures found on whale falls and other falls today, Dixon says, evolved
from creatures that hundreds of millions of years ago would have devoured plesiosaur (蛇颈龙)
falls.
22 ．What do we know about Osedax worms
A ．They depend on bones for survival. B ．They are newly evolved creatures.
C ．They are used to clean the ocean. D ．They prefer to live with whale falls.
23 ．Why were the dead bodies of three alligators handled that way
A ．To analyze the ocean food chain. B ．To observe how deep they would fall.
C ．To research on the structure of alligators. D ．To learn what would feed on their bones.
24 ．What does the underlined word “submerged” in the last but one paragraph mean
A ．Considered. B ．Required. C ．Sank. D ．Buried.
25 ．What does Dixon stress in the end
A ．The pressure on creatures to have food.
B ．The importance of studying falls in the ocean.
C ．The consequence of consuming plesiosaur falls.
D ．The influence of plesiosaur falls on the ecosystem.

In San Francisco, a large group of sea lions move themselves out of the bay waters and
hang out on PIER 39, which is a popular tourist destination. According to dock (码头) officials, this is the most sea lions seen in the region in 15 years.
“Over 1,000 sea lions have been counted this week,” PIER 39 harbor master Sheila
Chandor told many different medias. “The increase in sea lions is usually a good sign of their
strong population and healthy living environment,” said Adam Ratner, Director of Conservation Engagement at the Marine Mammal (海洋哺乳动物) Center in Sausalito, California.
“California sea lions are sentinels (哨兵) of the ocean,” Ratner said. Their population to some extent reflects the health of the ocean. Therefore, seeing a large number of California sea lions is clearly a good thing.
For nearly 35 years, the animals have been a star attraction for visitors. That autumn in
1989, PIER 39 had just been repaired, but the ships had not yet been moved back. At that moment, the sea lions’ unexpected arrival not only attracted fans but also created enemies. According to a
website, some dock residents and workers were scared away by the strong and very unpleasant smell and noise of their new neighbors, while others saw these animals as a bright spot after the destructive Loma Prieta earthquake.
The officials sought help from the Marine Mammal Center to find a way to deal with sea lions. Ratner said that the final decision is to let the sea lions stay and coexist with humans. “The fact prove that this is really a good thing,” he said. “This is just a proof of how we can truly work together at think about how we can share our coasts with marine mammals and other wildlife in a way that benefit all the parties involved.”
26 ．How does the author start the text
A ．By describing a scene. B ．By answering a question.
C ．By holding a conversation. D ．By comparing different opinions.
27 ．What does the increase of the sea lions mean
A ．The sea lions are migrating.
B ．The sea environment is good.
C ．The sea wildlife is threatened.
D ．The sea water should be cleaned.
试卷第 5 页，共 13 页
28 ．What can we learn from Ratner’s words
A ．He was uninterested in the sea lions.
B ．He was in favor of the final decision.
C ．He was doubtful about living with the sea lions.
D ．He was concerned about the situation of the sea lions.
29 ．What’s the main idea of the text
A ．Sea lions are pretty cool animals.
B ．Animals and humans can live in harmony.
C ．Watching sea lions is popular in San Francisco.
D ．The growing sea lions appear in San Francisco.
C
Jellyfish are a species of sea animals that are named because of their bodies.Despite the name,they are not fish.A jellyfish has no head,brain,heart,eyes,or ears.
Fossil evidence of these creatures dates back to over 650 million years ago,even earlier than dinosaurs.With so many kinds of jellyfish floating about,there must be variety in the appearance of their body parts.However,the typical body is made up of the bell,the oral arms and the tentacles(触手).
The bell of the jellyfish is the smooth umbrella-shaped body that is designed to pump.Inside the bell are the mouth and stomach.The digestive system is very simple.The stomach,which can be considered the jellyfish’s “inside”,is lined with cells.We can easily see their “inside” because
water takes up the major part of their bodies,the percentage of which is over 95%.
The jellyfish has no brain,but it does have a simple nervous system called a nerve net,which spreads throughout the outside layer of the animal’s skin.When the jellyfish comes in contact with potential danger,the cells of the nerve net respond by shooting out many tentacles.
Although the jellyfish does not have sensory organs,it does possess tiny simple sensory
structures.Their special structures in the body can react to light.Thus the jellyfish,though lacking a brain and eyes,can respond to sunlight shining through the water.It should be noted that,although it can perceive light,without eyes it cannot see images.
Jellyfish,because of their stinging(蜇人的)tentacles,can be dangerous to humans.Of the
试卷第 6 页，共 13 页
more than 2,000 species,roughly 70 are thought to be potentially dangerous to humans.The stings of some of these can even be deadly to humans,and may leave permanent scars on any victim who is lucky enough to survive.
30 ．What can be found in each jellyfish’s body
A ．A head.
B ．A heart.
C ．A digestive system.
D ．Sensory organs.
31 ．Why can the “inside” of jellyfish be easily seen
A ．Their bodies are umbrella-shaped.
B ．They have fewer cells.
C ．Their bodies mainly consist of water.
D ．They have very thin skin.
32 ．What does the underlined word “perceive” in paragraph 5 mean
A ．Absorb. B ．Sense.
C ．Recognize. D ．Judge.
33 ．What can be inferred from the passage
A ．Jellyfish’s digestive system is complex.
B ．Jellyfish share the same body appearance.
C ．Jellyfish protect themselves with their tentacles.
D ．Jellyfish’s attack makes people die immediately.

Researchers studying the brains of songbirds have found that aging influences the gene
expressions that control the birds’ song. The finding could lead to earlier diagnoses and better
treatments for human neurodegenerative (神经变性的) disorders such as Parkinson’s disease and Alzheimer’s disease, which affect vocal production in their early stages.
The study found that networks of interacting genes, in a region of the bird’s brain involved with singing, dramatically change as the bird ages. At the center of these networks are “hub genes (key control genes) ” that drive activity of many other genes. A better understanding of the hub
试卷第 7 页，共 13 页
genes could be crucial to developing treatments for age-related disorders.
Zebra finches (斑胸草雀), native to Australia, have a strikingly similar-looking brain to
humans’, particularly the brain movement-control area, which is used for motor function,
including speech. The finches also develop their birdsong by copying their parents and other birds around them — the same way humans learn to speak.
Perhaps most importantly to researchers, the birdsong is also a measurable marker for
changes in the brain, enabling scientists to track changes in sound height, volume, and strength. Researchers recorded the songs of 36 birds, ranging widely in age, and studied how the genes associated with singing began to behave differently as the birds grew older.
“There is some hopeful news in that the bird is still able to produce the song behavior, even with the genetic changes, and it suggests that there are also some ways that the bird is adapting to what’s going on in the brain,” says Miller, an associate professor in the neuroscience department. “This might offer recovery methods for humans.”
Miller says she hopes further research can shed more light on the changes to the hub genes as the finches age.
34 ．What role do hub genes play in the gene networks
A ．They make other genes function.
B ．They are direct age-related genes.
C ．They stay unchanged as birds age.
D ．They offer treatment to disorders.
35 ．What primarily makes finches suitable for brain aging research
A ．Their brain structure. B ．Their singing ability.
C ．Their relation to humans. D ．Their way of learning.
36 ．How did the researchers measure changes in the birdsong
A ．By observing the birds’ daily activities.
B ．By recording songs of birds of varying ages.
C ．By comparing songs to human vocal patterns.
D ．By changing the birds’ sound height of songs.
37 ．Which factor of songbirds can bring hope to humans in resisting aging
A ．Their genetic changes. B ．Their ability to adapt to aging.
试卷第 8 页，共 13 页
C ．Their changes to the hub genes. D ．Their act of producing the song.

What Are Grasslands
Grasslands are wide areas of land covered with low growing plants such as grasses and
wildflowers. Grasslands don’t get enough rain to grow tall trees and produce forests, but they get too much rain to form a desert. Temperate (温带的) grasslands have different seasons including hot summers and cold winters.
38
Grasslands are generally found between deserts and forests. The major temperate grasslands are located in central North America in the United States, in southeast South America in Uruguay and Argentina, and in Asia along the southern part of Russia and Mongolia.
39
A variety of animals live in the grasslands, including dogs, wolves, and eagles. A lot of smaller animals hide down in the grass, such as snakes, mice, and rabbits.
40
Different kinds of grass grow in different areas of the grasslands. There are actually
thousands of different kinds of grass that grow in this type of environment. Where they grow
usually depends on the amount of rain that area gets. In wetter grasslands, there are tall grasses
that can grow up to six feet high. In dryer areas the grasses grow shorter, maybe only a foot or two tall. Other plants that grow there include sunflowers, butterfly weeds, and butterweeds.
41
Grasslands play an important role in human farming and food production. They are used to grow crops such as wheat and corn. They are also good for feeding farm animals such as cows.
42
Unfortunately, human farming and development has caused the grasslands to become
gradually smaller. Governments have carried protection measures to try and save the grasslands

that are left, along with the endangered plants and animals that live there.
A ．The Narrowing Grasslands
B ．Animals in the Grasslands
C ．Some Important Temperate Grasslands in the World
D ．Farming and Food
E ．Wildfires in the Grasslands
F ．Types of Temperate Grasslands
G ．Plants in the Grasslands

One morning, my family and I woke up and went to eat breakfast—until we heard barking and scratching at the door. When my mom opened the door, we saw a puppy(小狗). We looked around to see if there was its owner, but there was no one. We took it inside and fed it.
Although I wanted to keep the puppy, we decided to look for the owner. We looked all day, but we failed. We planned to look for its owner the next day.
The next day my family and I looked for the dog's owner. It was so hard to find its owner. We were looking for flyers(传单) that involved the puppy, but no luck. We wouldn't have given

up because it's a puppy and it needs its owner.
“We won't stop looking for its owner, ” my mom and dad said to me. “And we are going to take care of the puppy until we find its owner. ”
Then we went to a pet shop to buy the puppy some dog food. After that we went back home to feed the puppy the dog food that we had just bought. It was so dirty that the fur was black and
sticky. So we gave it a nice bath. After we gave it a bath, it turned pure white. And I noticed there was a collar(狗项圈) on him, which said “Coby”. We decided to look for the puppy's owner
immediately. My mom stayed at home, and it was only my dad and me this time.
We continued looking for more information until we found a flyer about it. We looked at it and it said, “Lost Dog: Please Help If Found. ” Then we looked at the picture; it looked exactly
like Coby. We were all happy we found a flyer that was for Cody.

animal — milu deer (麋鹿). This kind of deer can be found only in parks and zoos in our country now. Generally speaking, a milu deer grows to a height of 1.2 meters. And a grown-up deer
weighs about 150 to 200 kilograms. In summer, the deer eat grass. In autumn, they eat nuts and
fruits which fell from the trees of the forest. In winter, when there is very little other food, they eat the dry leaves of the trees. The grown-up females give birth to their young in summer. When the

baby deer are strong enough to stand on their feet, they join their mothers. It’s very difficult to
catch them because they can smell danger from a long way away. Besides, they can hear and see very well, too. The difference between a milu deer and other deer is that the coat of milu deer is bright red in summer and gray in winter, and that their feet are bigger and their tails are longer.

【导语】本文是一篇说明文。研究人员将三只短吻鳄的尸体扔进海里来研究将会发生什么。
22 ．细节理解题。根据第一段中“They’ve only ever been spotted on bones, which makes some scientists think that the bone-eaters are specialized to live in odd ecosystems, such as whale
falls.(它们只在骨头上被发现过，这使得一些科学家认为食骨动物专门生活在奇怪的生态系统中，比如鲸鱼瀑布)”可知，Osedax 蠕虫依赖于死去的海洋动物的骨头生活。故选 A。
23．推理判断题。根据第二段中“Over the next few months, they sent a remote-controlled vehicle a few times to spy on what were essentially “alligator falls” .(在接下来的几个月里，他们几次派出遥控飞行器去监视本来的“鳄鱼瀑布”)” 以及第三段中“And just as at whale falls, it hosted a carpet of bone-eating Osedax worms.(就像在鲸鱼坠落的地方一样，这里也有大量吃骨头的
Osedax 蠕虫)”可知，把短吻鳄的尸体扔进海里是为了弄清楚会有哪些海洋生物以它们的骨头为食。故选 D。
24 ．词义猜测题。根据第二段中的“In early 2019, her group put the dead bodies of three
alligators(短吻鳄)in water about 2 kilometers deep.(2019 年初，她的团队将三只短吻鳄的尸体放入约 2 公里深的水中)”以及该段对此的归纳总结可知，这里是指他们将短吻鳄的尸体“沉入”海底来观察研究。故画线词意思是“沉入” 。故选 C。
25 ．推理判断题。根据最后一段“Studying alligator falls, Dixon says, could help show how life evolved(进化)in the deep sea. It’s possible that the creatures found on whale falls and other falls
today, Dixon says, evolved from creatures that hundreds of millions of years ago would have
devoured plesiosaur (蛇颈龙) falls.(迪克森说，研究短吻鳄坠落可以帮助展示深海生命是如何进化的。迪克森说，今天在鲸鱼瀑布和其他瀑布上发现的生物有可能是从数亿年前吞食蛇颈龙瀑布的生物进化而来的)”可知，该段中 Dixon 主要强调了研究落入海底的海洋生物尸体的重要性。故选 B。

27 ．细节理解题。根据第三段的““California sea lions are sentinels ofthe ocean,” Ratner said. Their population to some extent reflects the health of the ocean. Therefore, seeing a large number of California sea lions is clearly a good thing.(“加利福尼亚海狮是海洋的哨兵，”拉特纳说。它们的数量在某种程度上反映了海洋的健康状况。因此，看到大量的加州海狮显然是一件好事。) ”可知，海狮数量的增加意味着海洋环境很好。故选 B。
28．细节理解题。根据最后一段的“The officials sought help from the Marine Mammal Center to find a way to deal with sea lions.Ratner said that the final decision is to let the sea lions stay and
coexist with humans. “The fact prove that this is really a good thing,” he said. “This is just a proof of how we can truly work together at think about how we can share our coasts with marine
mammals and other wildlife in a way that benefit all the parties involved.”(官员们向海洋哺乳动物中心寻求帮助，以找到一种处理海狮的方法。拉特纳说，最终决定是让海狮留下来与人类共存。“事实证明，这确实是一件好事，”他说。“这只是一个证明，我们如何才能真正共同努力，思考如何与海洋哺乳动物和其他野生动物共享我们的海岸，让所有相关方都受
益。”)”可知，拉特纳对与海狮共存表达了积极的看法，人们应该思考如何让双方都受益，因此拉特纳赞成最后的决定，即让海狮留下来与人类共存。故选 B。
29 ．主旨大意题。通读全文，根据第一段的“In San Francisco, a large group of sea lions move themselves out of the bay waters and hang out on PIER 39, which is a popular tourist destination. According to dock officials, this is the most sea lions seen in the region in 15 years.(在旧金山，一大群海狮从海湾水域出来，在 39 号码头闲逛，这是一个受欢迎的旅游目的地。据码头官员称，这是 15 年来在该地区看到的最多的海狮。)”可知，本文的中心是围绕美国旧金山 PIER
39 码头出现了大量的海狮展开的，D 项(越来越多的海狮出现在旧金山)是文章的主要内容。故选 D 项。

33 ．推理判断题。根据第四段最后一句“When the jellyfish comes in contact with potential
danger,the cells of the nerve net respond by shooting out many tentacles.”（当水母接触到潜在的危险时，神经网的细胞会伸出许多触角做出反应。）可知, 当遇到危险时,水母就会伸出触手来保护自己。故选 C 项。

因）”, 它们驱动着许多其他基因的活动。)”可知，中枢基因在基因网络中的作用是使其他基因发挥功能。故选 A 项。
35 ．推理判断题。根据第三段中的“Zebra finches (斑胸草雀), native to Australia, have a
strikingly similar-looking brain to humans’, particularly the brain movement-control area, which
is used for motor function, including speech.(原产于澳大利亚的斑胸草雀，其大脑结构与人类惊人地相似，尤其是用于运动功能（包括语言）的大脑运动控制区域。)” 以及第四段中的
“Perhaps most importantly to researchers, the birdsong is also a measurable marker for changes in the brain, enabling scientists to track changes in sound height, volume, and strength.(对研究人员 来说，或许最重要的是，鸟鸣也是大脑变化的可测量标志，这使科学家能够追踪声音高度、音量和强度的变化。)”可知，斑胸草雀适合用于大脑衰老研究，主要是因为其大脑结构与人类相似，且鸟鸣能作为大脑变化的可测量标志，核心在于大脑结构，由此可知，草雀的脑结
答案第 6 页，共 13 页
构使其适合进行脑老化研究。故选 A 项。
36．细节理解题。根据第四段中的“Researchers recorded the songs of 36 birds, ranging widely in age, and studied how the genes associated with singing began to behave differently as the birds
grew older.(研究人员记录了 36 只年龄跨度很大的鸟的鸣叫，并研究了随着鸟年龄增长，与鸣叫相关的基因是如何开始表现出不同行为的。)”可知，研究人员通过记录不同年龄鸟类的鸣叫来测量鸟鸣的变化。故选 B 项。
37 ．细节理解题。根据第五段中的““There is some hopeful news in that the bird is still able to produce the song behavior, even with the genetic changes, and it suggests that there are also some ways that the bird is adapting to what’s going on in the brain,” says Miller, an associate professor in the neuroscience department. “This might offer recovery methods for humans.”(米勒说：“有一个好消息是，即使基因发生了变化，这种鸟仍然能够进行鸣叫行为，这表明这种鸟也有一些方法来适应大脑中发生的变化。这可能为人类提供恢复方法”)”可知，鸣禽对衰老的适应能力为人类抵抗衰老带来了希望。故选 B 项。

A
Osedax worms have been found in oceans all over the world. They’ve only ever been
spotted on bones, which makes some scientists think that the bone-eaters are specialized to live in odd ecosystems, such as whale falls. “Those kinds of animals are definitely uniquely adapted to
the environment in which you find them, ”says marine biologist River Dixon. She is a graduate student at the University of Louisiana at Lafayette.
But as recent experiments show, the bone-eaters may not be picky about what type of bones they devour(吞食). Last year, biologists spotted Osedax worms in the Gulf of Mexico for the first time. And not on whale bones. Dixon was part of a research team that made the discovery. In early 2019, her group put the dead bodies of three alligators(短吻鳄)in water about 2 kilometers deep. Over the next few months, they sent a remote-controlled vehicle a few times to spy on what were
试卷第 3 页，共 13 页
essentially “alligator falls”.
51 days after the alligators were placed in the seawater, scientists revisited. “The flesh was gone”, Dixon says. . “It had been reduced to just the skeleton(骨骼).” And just as at whale falls, it hosted a carpet of bone-eating Osedax worms. These worms were similar to other bone-eaters but represented a never-before observed species. That means the scientists who found them get to
name it (although Dixon says they haven’t settled on a name yet).
The lab where Dixon works studies food systems in the deep ocean. Algae and plants use
photosynthesis(光合作用)to turn sunlight into food. Animals eat those plants and algae to survive. Then larger animals may eat those animals. But sunlight doesn’t reach the deep ocean’s bottom.
So other pathways are essential. These pathways include whale falls and other dead bodies. The scientists wondered how alligator falls fit into a larger food web. To find out, they submerged
them.
Studying alligator falls, Dixon says, could help show how life evolved(进化)in the deep sea. It’s possible that the creatures found on whale falls and other falls today, Dixon says, evolved
from creatures that hundreds of millions of years ago would have devoured plesiosaur (蛇颈龙)
falls.
22 ．What do we know about Osedax worms
A ．They depend on bones for survival. B ．They are newly evolved creatures.
C ．They are used to clean the ocean. D ．They prefer to live with whale falls.

A ．To analyze the ocean food chain. B ．To observe how deep they would fall.
C ．To research on the structure of alligators. D ．To learn what would feed on their bones.
24 ．What does the underlined word “submerged” in the last but one paragraph mean
A ．Considered. B ．Required. C ．Sank. D ．Buried.
25 ．What does Dixon stress in the end
A ．The pressure on creatures to have food.
B ．The importance of studying falls in the ocean.
C ．The consequence of consuming plesiosaur falls.
D ．The influence of plesiosaur falls on the ecosystem.

In San Francisco, a large group of sea lions move themselves out of the bay waters and
hang out on PIER 39, which is a popular tourist destination. According to dock (码头) officials, this is the most sea lions seen in the region in 15 years.
“Over 1,000 sea lions have been counted this week,” PIER 39 harbor master Sheila
Chandor told many different medias. “The increase in sea lions is usually a good sign of their
strong population and healthy living environment,” said Adam Ratner, Director of Conservation Engagement at the Marine Mammal (海洋哺乳动物) Center in Sausalito, California.
“California sea lions are sentinels (哨兵) of the ocean,” Ratner said. Their population to some extent reflects the health of the ocean. Therefore, seeing a large number of California sea lions is clearly a good thing.
For nearly 35 years, the animals have been a star attraction for visitors. That autumn in
1989, PIER 39 had just been repaired, but the ships had not yet been moved back. At that moment, the sea lions’ unexpected arrival not only attracted fans but also created enemies. According to a
website, some dock residents and workers were scared away by the strong and very unpleasant smell and noise of their new neighbors, while others saw these animals as a bright spot after the destructive Loma Prieta earthquake.
The officials sought help from the Marine Mammal Center to find a way to deal with sea lions. Ratner said that the final decision is to let the sea lions stay and coexist with humans. “The fact prove that this is really a good thing,” he said. “This is just a proof of how we can truly work together at think about how we can share our coasts with marine mammals and other wildlife in a way that benefit all the parties involved.”
26 ．How does the author start the text
A ．By describing a scene. B ．By answering a question.
C ．By holding a conversation. D ．By comparing different opinions.
27 ．What does the increase of the sea lions mean
A ．The sea lions are migrating.
B ．The sea environment is good.
C ．The sea wildlife is threatened.
D ．The sea water should be cleaned.

28 ．What can we learn from Ratner’s words
A ．He was uninterested in the sea lions.
B ．He was in favor of the final decision.
C ．He was doubtful about living with the sea lions.
D ．He was concerned about the situation of the sea lions.
29 ．What’s the main idea of the text
A ．Sea lions are pretty cool animals.
B ．Animals and humans can live in harmony.
C ．Watching sea lions is popular in San Francisco.
D ．The growing sea lions appear in San Francisco.

Jellyfish are a species of sea animals that are named because of their bodies.Despite the name,they are not fish.A jellyfish has no head,brain,heart,eyes,or ears.
Fossil evidence of these creatures dates back to over 650 million years ago,even earlier than dinosaurs.With so many kinds of jellyfish floating about,there must be variety in the appearance of their body parts.However,the typical body is made up of the bell,the oral arms and the tentacles(触手).
The bell of the jellyfish is the smooth umbrella-shaped body that is designed to pump.Inside the bell are the mouth and stomach.The digestive system is very simple.The stomach,which can be considered the jellyfish’s “inside”,is lined with cells.We can easily see their “inside” because
water takes up the major part of their bodies,the percentage of which is over 95%.
The jellyfish has no brain,but it does have a simple nervous system called a nerve net,which spreads throughout the outside layer of the animal’s skin.When the jellyfish comes in contact with potential danger,the cells of the nerve net respond by shooting out many tentacles.
Although the jellyfish does not have sensory organs,it does possess tiny simple sensory
structures.Their special structures in the body can react to light.Thus the jellyfish,though lacking a brain and eyes,can respond to sunlight shining through the water.It should be noted that,although it can perceive light,without eyes it cannot see images.
Jellyfish,because of their stinging(蜇人的)tentacles,can be dangerous to humans.Of the
试卷第 6 页，共 13 页
more than 2,000 species,roughly 70 are thought to be potentially dangerous to humans.The stings of some of these can even be deadly to humans,and may leave permanent scars on any victim who is lucky enough to survive.
30 ．What can be found in each jellyfish’s body
A ．A head.
B ．A heart.
C ．A digestive system.
D ．Sensory organs.
31 ．Why can the “inside” of jellyfish be easily seen
A ．Their bodies are umbrella-shaped.
B ．They have fewer cells.
C ．Their bodies mainly consist of water.
D ．They have very thin skin.
32 ．What does the underlined word “perceive” in paragraph 5 mean
A ．Absorb. B ．Sense.
C ．Recognize. D ．Judge.
33 ．What can be inferred from the passage
A ．Jellyfish’s digestive system is complex.
B ．Jellyfish share the same body appearance.
C ．Jellyfish protect themselves with their tentacles.
D ．Jellyfish’s attack makes people die immediately.

Researchers studying the brains of songbirds have found that aging influences the gene
expressions that control the birds’ song. The finding could lead to earlier diagnoses and better
treatments for human neurodegenerative (神经变性的) disorders such as Parkinson’s disease and Alzheimer’s disease, which affect vocal production in their early stages.
The study found that networks of interacting genes, in a region of the bird’s brain involved with singing, dramatically change as the bird ages. At the center of these networks are “hub genes (key control genes) ” that drive activity of many other genes. A better understanding of the hub
试卷第 7 页，共 13 页
genes could be crucial to developing treatments for age-related disorders.
Zebra finches (斑胸草雀), native to Australia, have a strikingly similar-looking brain to
humans’, particularly the brain movement-control area, which is used for motor function,
including speech. The finches also develop their birdsong by copying their parents and other birds around them — the same way humans learn to speak.
Perhaps most importantly to researchers, the birdsong is also a measurable marker for
changes in the brain, enabling scientists to track changes in sound height, volume, and strength. Researchers recorded the songs of 36 birds, ranging widely in age, and studied how the genes associated with singing began to behave differently as the birds grew older.
“There is some hopeful news in that the bird is still able to produce the song behavior, even with the genetic changes, and it suggests that there are also some ways that the bird is adapting to what’s going on in the brain,” says Miller, an associate professor in the neuroscience department. “This might offer recovery methods for humans.”
Miller says she hopes further research can shed more light on the changes to the hub genes as the finches age.
34 ．What role do hub genes play in the gene networks
A ．They make other genes function.
B ．They are direct age-related genes.
C ．They stay unchanged as birds age.
D ．They offer treatment to disorders.
35 ．What primarily makes finches suitable for brain aging research
A ．Their brain structure. B ．Their singing ability.
C ．Their relation to humans. D ．Their way of learning.
36 ．How did the researchers measure changes in the birdsong
A ．By observing the birds’ daily activities.
B ．By recording songs of birds of varying ages.
C ．By comparing songs to human vocal patterns.
D ．By changing the birds’ sound height of songs.
37 ．Which factor of songbirds can bring hope to humans in resisting aging
A ．Their genetic changes. B ．Their ability to adapt to aging.

C ．Their changes to the hub genes. D ．Their act of producing the song.

What Are Grasslands
Grasslands are wide areas of land covered with low growing plants such as grasses and
wildflowers. Grasslands don’t get enough rain to grow tall trees and produce forests, but they get too much rain to form a desert. Temperate (温带的) grasslands have different seasons including hot summers and cold winters.
38
Grasslands are generally found between deserts and forests. The major temperate grasslands are located in central North America in the United States, in southeast South America in Uruguay and Argentina, and in Asia along the southern part of Russia and Mongolia.
39
A variety of animals live in the grasslands, including dogs, wolves, and eagles. A lot of smaller animals hide down in the grass, such as snakes, mice, and rabbits.
40
Different kinds of grass grow in different areas of the grasslands. There are actually
thousands of different kinds of grass that grow in this type of environment. Where they grow
usually depends on the amount of rain that area gets. In wetter grasslands, there are tall grasses
that can grow up to six feet high. In dryer areas the grasses grow shorter, maybe only a foot or two tall. Other plants that grow there include sunflowers, butterfly weeds, and butterweeds.
41
Grasslands play an important role in human farming and food production. They are used to grow crops such as wheat and corn. They are also good for feeding farm animals such as cows.
42
Unfortunately, human farming and development has caused the grasslands to become
gradually smaller. Governments have carried protection measures to try and save the grasslands

A ．The Narrowing Grasslands
B ．Animals in the Grasslands
C ．Some Important Temperate Grasslands in the World
D ．Farming and Food
E ．Wildfires in the Grasslands
F ．Types of Temperate Grasslands

One morning, my family and I woke up and went to eat breakfast—until we heard barking and scratching at the door. When my mom opened the door, we saw a puppy(小狗). We looked around to see if there was its owner, but there was no one. We took it inside and fed it.
Although I wanted to keep the puppy, we decided to look for the owner. We looked all day, but we failed. We planned to look for its owner the next day.
The next day my family and I looked for the dog's owner. It was so hard to find its owner. We were looking for flyers(传单) that involved the puppy, but no luck. We wouldn't have given

up because it's a puppy and it needs its owner.
“We won't stop looking for its owner, ” my mom and dad said to me. “And we are going to take care of the puppy until we find its owner. ”
Then we went to a pet shop to buy the puppy some dog food. After that we went back home to feed the puppy the dog food that we had just bought. It was so dirty that the fur was black and
sticky. So we gave it a nice bath. After we gave it a bath, it turned pure white. And I noticed there was a collar(狗项圈) on him, which said “Coby”. We decided to look for the puppy's owner
immediately. My mom stayed at home, and it was only my dad and me this time.
We continued looking for more information until we found a flyer about it. We looked at it and it said, “Lost Dog: Please Help If Found. ” Then we looked at the picture; it looked exactly
like Coby. We were all happy we found a flyer that was for Cody.

animal — milu deer (麋鹿). This kind of deer can be found only in parks and zoos in our country now. Generally speaking, a milu deer grows to a height of 1.2 meters. And a grown-up deer
weighs about 150 to 200 kilograms. In summer, the deer eat grass. In autumn, they eat nuts and
fruits which fell from the trees of the forest. In winter, when there is very little other food, they eat the dry leaves of the trees. The grown-up females give birth to their young in summer. When the
