一、阅读理解
（2022高三下·绵阳模拟）
阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
The world's only
captive(圈养) brown giant panda, Qizai,
has been taking more exercise in preparation for the upcoming breeding(繁育) season. He is encouraged to stand up by keepers who place food on
the end of a stick held just out of his reach. Panda experts believe that
strengthening the giant animal's legs will improve his ability to breed
successfully.
The world's first
brown panda was discovered in 1985 in the Qinling Mountains. All photographs of
wild brown pandas were taken in the area, which they were named after. The
Qinling giant panda, first recognized in 2005, is a subspecies of giant panda. As
well as its brown and white fur, it has a smaller and rounder skull and a
shorter nose than the more familiar Sichuan giant panda.
Qizai, whose name
means the seventh son, was found as a two-month-old cub, weak and alone, by
researchers in a nature reserve in the Qinling Mountains. For his safety, the
researchers took him to the nearby Shanxi Rare Wildlife Rescue Centre where he
was given medical treatment and fed on milk from other pandas.
There are 1,864 giant
pandas in the wild, according to World Wildlife. They live mainly in bamboo
forests high in the mountains of south-west China, mostly in Sichuan province,
but they can also be found in Shanxi province, where Qizai is from. He was
previously thought to be the only living brown panda in the world until a wild panda
with the same colour pattern was spotted roaming in a nature reserve in Shanxi in
March, 2018.Up to now spotting brown pandas in the wild has taken place no more
than ten times, all of which were in the central Qinling Mountains.
1．Why do keepers put food beyond Qizai's reach
A．To prepare him for the return to the wild.
B．To train him to amuse zoo visitors.
C．To help him exercise his legs.
D．To ensure him a balanced diet.
2．What can we infer about Qizai from the text
A．He was first found in 2005.
B．He is a Qinling giant panda.
C．His seventh son is 2 months old.
D．He was the only living brown panda.
3．What conclusion can be drawn from the last paragraph
A．The sighting of wild brown pandas is a rare happening.
B．The Qinling Mountains are home to most wild pandas.
C．The number of giant pandas is growing rapidly.
D．All giant pandas are of the same colour.
4．What's the text mainly about
A．Life of captive pandas. B．Endangered giant pandas.
C．The Qinling giant panda. D．Rare wildlife protection.

In contrast to the brightly coloured species of birds, most of mammals are browns and greys, but with a small number of exceptions, of which the most famous. is the giant panda. We've had some initial assumption about why they had their markings, but we need to confirm the reason for its mysterious pattern.
Viewed up close in a zoo, the giant panda is a strikingly notable mix of a white bear with black shoulders and legs, and an extraordinary face with black fur around the eyes and ears. By comparing with other carnivores （食肉动物）， we learned that carnivores with white backs are found in snowy environments, and those with dark legs and shoulders are found in shady habitats. This suggested that the fur was an adaptation to be self-protective in different environments.
Nowadays, giant pandas are confined to forests in western China, where they live on their own and there are relatively few predators （捕食者）. We are to confirm that the sort of self-protection is effective against giant pandas' former predators from the days when they ranged right across China into Vietnam.
By comparing the amount of light reflected from the giant panda's fur with natural objects in the background, it's clear that their black fur patches （斑纹） match dark shades and tree trunks, whereas their white patches match bright leaves and snow. Also, pale brown, or muddy fur matches the color of the ground. This provides a medium color which bridges the gap between the very dark and very light visual elements in the natural habitat. Besides, a second form of self-protection lies in something termed misorderly colors and patterns-in which highly visible patches break up its outline by mixing with patches in the background.
Giant pandas show this form of defensive outline, especially at longer viewing distances of at least 60 meters away. At these distances, the giant panda becomes hardly identifiable as the black fur patches go with the background, dark rocks and tree trunks.
Although giant pandas in zoos are highly notable to us, it is because we see them up close and surrounded by artificial backgrounds. But when in the wild and at a distance, our research shows that they are beautifully protective to avoid detection.
5．How are giant pandas different from most mammals
A．They are more brightly colored.
B．They are marked with browns and greys.
C．They have exceptional colors and patterns.
D．Their dark legs match snowy environments.
6．Which can interpret the underlined part "confined to" in paragraph 3
A．Enclosed in. B．Raised in. C．Lost in. D．Trained in.
7．What is the purpose of paragraph 4
A．To explain the reason for pandas living in the wild.
B．To confirm the panda's color connection to the habitat.
C．To compare the differences of pandas' body parts in color.
D．To conclude the relationship between light and pandas' colors.
8．What can we infer about giant pandas from the last two paragraphs
A．They look darker in the artificial background.
B．Their patterns are determined by their whereabouts.
C．The effectiveness of defensive colors is related to distance.
D．They are more beautifully-colored in the wild than in the zoo.

Pandas are famously picky eaters. They only consume bamboo — a poor quality diet low in fat. But the creatures appear to have evolved to get the most out of what they do eat, according to a new study.
Their gut (肠道) bacteria change in late spring and early summer when bamboo is at its most nutritious — while protein-rich green shoots are coming out. The bacteria make the panda gain more weight and store more fat, which researchers said may compensate for a lack of nutrients later in the year, when bamboo plants have only fibrous leaves to chew.
“We've known these pandas have a different set of gut microbiota during the shoot-eating season for a long time, and it's very obvious that they are chubbier during this time of the year,” said lead study author Guangping Huang, a researcher for the Institute of Zoology at the Chinese Academy of Sciences.
To investigate how the gut bacteria could affect a panda's digestion, the team first collected the wastes of eight wild giant pandas in China's Qinling Mountains during both leaf eating season and shoot-eating season and then examined how the waste samples differed. They found a bacterium called Clostridium butyricum was more abundant in the pandas' guts during the season when they enjoy the fresh bamboo shoots.
To understand whether this bacterium helps the pandas gain and store weight, the researchers put the panda wastes they collected into lab mice. Then they fed the mice for three weeks with a bamboo-based diet that simulated (模仿) what pandas cat. Researchers found the mice Which were transplanted with panda wastes collected during shoot-eating season gained significantly more weight than the ones which were not, despite consuming same amount of food.
“The gut bacteria were the only variable (变量) in this research,” Wei explained. However, Felix Sommer at Christian-Albrechts-University in Kiel, Germany, noted the number of pandas studied was small and that the experiment had only been performed once. Sommer also stressed the researchers had found a link, not a causal relationship between the bacteria and weight gain.
9．When do pandas get more weight with the change of their gut bacteria
A．In late spring. B．In late summer.
C．In early autumn. D．In early winter.
10．What does the underlined word “chubbier” in paragraph 3 mean
A．Smaller. B．Slimmer. C．Taller. D．Fatter.
11．What can we learn from the experiment on mice
A．The experiment lasted for less than three weeks.
B．Researchers collected bacteria from the lab mice.
C．Panda wastes have a vital effect on mice's weight.
D．Different amounts of food led to an increase in weight.
12．What is the best title for the text
A．Studies on Eating Habits of Pandas
B．Functions of Pandas' Gut Bacteria
C．Characteristics of Pandas' Daily Diet
D．Arguments over Pandas' Digestion System

At first glance, it seems that giant pandas (大熊猫) might not be good at hide- and-seek. With their black and white coats, they appear to have a hard time matching their backgrounds and avoiding detection by their enemies. But a new study finds that the unique markings, in fact, provide effective camouflage (伪装) and help them disappear into their surroundings. Scientists have long wondered what function the black-and-white coloring plays.
For their study, researchers analyzed photos of giant pandas in their natural habitats. "We've found that the animals are very well camouflaged because they use habitats with dark and lighting conditions, and also snow during some time of the year," study author Tim Caro of the University of Bristol and the University of California, Davis, tells Treehugger.
They found that the black patches (块) of fur match primarily shade and dark tree trunks. They also match the ground, rocks and leaves. The white fur patches match snow, rocks, and waxy, bright leaves. Sometimes pandas also have patches of pale brown fur and those match rocks, ground and shady background areas.
The researchers also explored a type of environmental camouflage known as disruptive coloration. That's when highly contrasting patterns or very visible boundaries on an animal break up its body outline. They found that the black and white borders on the panda's coat make it less noticeable, particularly from farther away.
It might seem a bit confusing because giant pandas are very easy to spot at a zoo, for instance. But the environment and the viewer make a difference.
"We modelled their coloration through enemies' eyes as well as how humans see them so we are sure of the results." Caro says.
"It seems that giant pandas appear easily noticeable to us because of short viewing distances and unnatural backgrounds, when we see them, either in photographs or at the zoo, it is almost always from close up, and often against a backdrop that doesn't reflect their natural habitats," says author Nick Scott-Samuel of the University of Bristol. "From a more realistic enemy's view, the giant panda is actually rather well camouflaged."
13．What is the general first impression of giant pandas
A．They like staying away from humans.
B．They are really good at hide-and-seek.
C．They match the backgrounds very well.
D．They can be easily detected by enemies
14．What does the underlined word "They" in paragraph 3 refer to
A．Tree trunks. B．Pale brown pandas.
C．Black fur patches. D．Shady background areas
15．What can we learn about giant pandas from Nick Scott-Samuel's words
A．They are less noticeable in natural environments.
B．They can be easily noticed even from farther away.
C．They often disappear into backgrounds in a zoo.
D．They can not camouflage from an enemy's view.
16．What can be a suitable title for the text
A．Giant Pandas Hide Themselves From Tourists
B．Giant Pandas Are Actually Good at Camouflaging
C．The Black-and-white Coloring Proves Appealing
D．You Are More Likely to Spot Giant Pandas in Nature
二、任务型阅读
17．（2020·金山模拟）Directions: Read the following. Fill in each blank with a
proper sentence given in the box. Each sentence can be used only once. Note
that there are two more sentences than you need.
A.
Between August and April, they sought food in low elevations (海拔) on China's Qinling Mountains. B.
Scientists think the research show that pandas are very clever. C.
Pandas eat bamboo all day long except when they are sleeping or playing. D.
The gene for their “umami taste receptors” became inactive. E.
They fed on them until they went back down the mountain and started eating
Bashania fargesii leaves again. F.
Scientists have conducted many studies on pandas' eating habits.
Are Bamboo-Eating Pandas
Really Herbivores
On
the outside, giant pandas look like herbivores (食草动物).
They spend nearly all of their waking hours eating bamboo. But on the inside,
they're built like carnivores (食肉动物). About half of the
calories they eat come from protein, according to a new study.
The
ancestor of giant pandas were omnivorous(杂食的).
They are both animals and plants, and had the digestive system and gut bacteria
to metabolize(使发生新陈代谢)them. They had "umami taste
receptors," to appreciate the flavors of meat.
However,
about 2.4 million years ago, things began to change. Their jaw and
teeth evolved to help them crush bamboo, and their wrist bone became capable of
grasping the stalk(杆)of their favorite plant.
Scientists think pandas switched to eating bamboo partly because they didn't
have to fight with other animals to get it. Bamboo is high in fiber but has a
low concentration of nutrients, so pandas have to eat 20 to 40 pounds of the
plant every day just to get by.
David
Raubenheimer, a nutritional ecologist at the University of Sydney, and his
colleagues put GPS trackers on two giant pandas and followed their movement
throughout the year. They discovered that the pandas followed the protein.
At the start of the cycle, they ate Bashania fargesii leaves until
they got the chance to feast on young shoots, which contained more protein.
The
more the shoots grew, the more their protein was diluted(冲淡)by fiber. That caused the pandas to move to higher ground, where
Fargesia qinlingensis grew. First, they ate the shoots, but these, too, went
from being protein - rich to fiber-rich as they grew. The panda responded by
switching to the leaves. The researchers found that about half of the
calories the pandas ate were in the form of protein.
"They can know exactly where to go, and when to go, so they can get the
most of the nutrients that their ecosystem can provide," said Silvia
Pineda - Munoz, who was not involved in the study.
The
work also shows that classifying an animals as herbivore or carnivore is more
complex than one might sassume. "It's not whether you're eating plants but
what of the plants you're eating," said Pineda - Munoz.

阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
The world's only
captive(圈养) brown giant panda, Qizai,
has been taking more exercise in preparation for the upcoming breeding(繁育) season. He is encouraged to stand up by keepers who place food on
the end of a stick held just out of his reach. Panda experts believe that
strengthening the giant animal's legs will improve his ability to breed
successfully.
The world's first
brown panda was discovered in 1985 in the Qinling Mountains. All photographs of
wild brown pandas were taken in the area, which they were named after. The
Qinling giant panda, first recognized in 2005, is a subspecies of giant panda. As
well as its brown and white fur, it has a smaller and rounder skull and a
shorter nose than the more familiar Sichuan giant panda.
Qizai, whose name
means the seventh son, was found as a two-month-old cub, weak and alone, by
researchers in a nature reserve in the Qinling Mountains. For his safety, the
researchers took him to the nearby Shanxi Rare Wildlife Rescue Centre where he
was given medical treatment and fed on milk from other pandas.
There are 1,864 giant
pandas in the wild, according to World Wildlife. They live mainly in bamboo
forests high in the mountains of south-west China, mostly in Sichuan province,
but they can also be found in Shanxi province, where Qizai is from. He was
previously thought to be the only living brown panda in the world until a wild panda
with the same colour pattern was spotted roaming in a nature reserve in Shanxi in
March, 2018.Up to now spotting brown pandas in the wild has taken place no more
than ten times, all of which were in the central Qinling Mountains.
1．Why do keepers put food beyond Qizai's reach
A．To prepare him for the return to the wild.

A．He was first found in 2005.
B．He is a Qinling giant panda.
C．His seventh son is 2 months old.
D．He was the only living brown panda.
3．What conclusion can be drawn from the last paragraph
A．The sighting of wild brown pandas is a rare happening.
B．The Qinling Mountains are home to most wild pandas.
C．The number of giant pandas is growing rapidly.
D．All giant pandas are of the same colour.
4．What's the text mainly about

【解析】【分析】本文是一篇说明文，介绍了秦岭大熊猫的相关知识。
【点评】本题考点涉及细节理解，推理判断和主旨大意三个题型的考查，是一篇科普类阅读，要求考生在捕捉细节信息的基础上，进一步根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。
1．考查细节理解。根据第一段中的“He is encouraged to stand up by keepers who place food on the end of a stick held just out of his reach. Panda experts believe that strengthening the giant animal's legs will improve his ability to breed successfully.”饲养员把食物放在它够不到的一根棍子上，鼓励它站起来。熊猫专家认为，加强这种巨型动物的腿能提高它成功繁殖的能力。可知，饲养员把食物放在七仔够不着的棍子上是为了锻炼它的腿，以提高成功繁育的能力。故选C。
2．考查推理判断。根据第二段中的“All photographs of wild brown pandas were taken in the area, which they were named after.”所有野生棕色大熊猫的照片都是在该地区（秦岭）拍摄的，它们是以该地区命名的；以及第三段中的“Qizai, whose name means the seventh son, was found as two-month-old cub, weak and alone, by researchers in a nature reserve in the Qinling Mountains.”研究人员在秦岭自然保护区发现了七仔，它只有两个月大，身体虚弱，孤独无依。可知，七仔是一只秦岭棕色大熊猫。故选B。
3．考查细节理解。根据最后一段中的“Up to now spotting brown pandas in the wild has taken place no more than ten times, all of which were in the central Qinling Mountains.”到目前为止，在野外发现棕色大熊猫的次数不超过10次，都是在秦岭中部。可推知，看到野生棕色大熊猫是很罕见的事。故选A。
4．考查主旨大意。通读全文可知，第二段指出在秦岭发现的棕色大熊猫都叫秦岭大熊猫，第三段介绍七仔在秦岭被发现的经过，第四段介绍野生棕色大熊猫几乎都在秦岭被发现。可知，本文主要介绍秦岭大熊猫。故选C。

In contrast to the brightly coloured species of birds, most of mammals are browns and greys, but with a small number of exceptions, of which the most famous. is the giant panda. We've had some initial assumption about why they had their markings, but we need to confirm the reason for its mysterious pattern.
Viewed up close in a zoo, the giant panda is a strikingly notable mix of a white bear with black shoulders and legs, and an extraordinary face with black fur around the eyes and ears. By comparing with other carnivores （食肉动物）， we learned that carnivores with white backs are found in snowy environments, and those with dark legs and shoulders are found in shady habitats. This suggested that the fur was an adaptation to be self-protective in different environments.
Nowadays, giant pandas are confined to forests in western China, where they live on their own and there are relatively few predators （捕食者）. We are to confirm that the sort of self-protection is effective against giant pandas' former predators from the days when they ranged right across China into Vietnam.
By comparing the amount of light reflected from the giant panda's fur with natural objects in the background, it's clear that their black fur patches （斑纹） match dark shades and tree trunks, whereas their white patches match bright leaves and snow. Also, pale brown, or muddy fur matches the color of the ground. This provides a medium color which bridges the gap between the very dark and very light visual elements in the natural habitat. Besides, a second form of self-protection lies in something termed misorderly colors and patterns-in which highly visible patches break up its outline by mixing with patches in the background.

Although giant pandas in zoos are highly notable to us, it is because we see them up close and surrounded by artificial backgrounds. But when in the wild and at a distance, our research shows that they are beautifully protective to avoid detection.
5．How are giant pandas different from most mammals
A．They are more brightly colored.
B．They are marked with browns and greys.
C．They have exceptional colors and patterns.
D．Their dark legs match snowy environments.
6．Which can interpret the underlined part "confined to" in paragraph 3
A．Enclosed in. B．Raised in. C．Lost in. D．Trained in.
7．What is the purpose of paragraph 4
A．To explain the reason for pandas living in the wild.
B．To confirm the panda's color connection to the habitat.
C．To compare the differences of pandas' body parts in color.
D．To conclude the relationship between light and pandas' colors.
8．What can we infer about giant pandas from the last two paragraphs
A．They look darker in the artificial background.
B．Their patterns are determined by their whereabouts.
C．The effectiveness of defensive colors is related to distance.
D．They are more beautifully-colored in the wild than in the zoo.

5．考查细节理解。根据第一段中的"In contrast to the brightly coloured species of birds, most of mammals are browns and greys, but with a small number of exceptions, of which the most famous is the giant panda."与色彩鲜艳的鸟类相比，大多数哺乳动物都是棕色和灰色的，但也有少数例外，其中最著名的是大熊猫；以及"We've had some initial assumption about why they had their markings, but we need to confirm the reason for its mysterious pattern."我们对它们为什么有这些标记有一些初步的假设，但我们需要确认其神秘图案的原因。可知，与大多数哺乳动物不同，大熊猫有着独特的颜色和图案。故选C。
6．考查词义猜测。根据第三段中的"We are to confirm that the sort of self-protection is effective against giant pandas' former predators from the days when they ranged right across China into Vietnam."我们要确认的是，这种自我保护对大熊猫从前的捕食者是有效的，那时他们从中国一直跑到越南。可知，从前的大熊猫生活范围遍及中国到越南，它们的捕食者也很多；结合n and there are relatively few predators (捕食者)."如今，大熊猫被confined to中国西部的森林里，在那里它们独自生活，捕食者相对较少。可推知，现在的大熊猫只在中国西部森林里独自生活，捕食者也较少，应该是被限制在了中国西部森林里，划线词confined to表示"被限制、封闭在了……中"。故选A。
7．考查推理判断。根据第四段中的"This provides a medium color which bridges the gap between the very dark and very light visual elements in the natural habitat."这提供了一种中等颜色，弥合了自然栖息地中非常黑暗和非常明亮的视觉元素之间的差距。可知，该段主要通过对大熊猫颜色的分析，证实了它与栖息地之间的联系。故选B。
8．考查推理判断。根据倒数第二段"Giant pandas show this form of defensive outline, especially at longer viewing distances of at least 60 meters away. At these distances, the giant panda becomes hardly identifiable as the black fur patches go with the background, dark rocks and tree trunks."大熊猫表现出这种形式的防御外形，特别是在至少60米以外的较远距离观看时，在这样的距离上，大熊猫的黑色皮毛与背景、深色岩石和树干相得益彰，几乎无法辨认；以及最后一段中的"But when in the wild and at a distance, our research shows that they are beautifully protective to avoid detection."但当在野外和远处时，我们的研究表明，它们会很好地保护自己，避免被发现。可知，在远处观看大熊猫，它们的颜色会起到很好的保护效果，可见大熊猫的这种防御颜色的保护效果与距离有关。故选C。

Pandas are famously picky eaters. They only consume bamboo — a poor quality diet low in fat. But the creatures appear to have evolved to get the most out of what they do eat, according to a new study.

To investigate how the gut bacteria could affect a panda's digestion, the team first collected the wastes of eight wild giant pandas in China's Qinling Mountains during both leaf eating season and shoot-eating season and then examined how the waste samples differed. They found a bacterium called Clostridium butyricum was more abundant in the pandas' guts during the season when they enjoy the fresh bamboo shoots.
To understand whether this bacterium helps the pandas gain and store weight, the researchers put the panda wastes they collected into lab mice. Then they fed the mice for three weeks with a bamboo-based diet that simulated (模仿) what pandas cat. Researchers found the mice Which were transplanted with panda wastes collected during shoot-eating season gained significantly more weight than the ones which were not, despite consuming same amount of food.
“The gut bacteria were the only variable (变量) in this research,” Wei explained. However, Felix Sommer at Christian-Albrechts-University in Kiel, Germany, noted the number of pandas studied was small and that the experiment had only been performed once. Sommer also stressed the researchers had found a link, not a causal relationship between the bacteria and weight gain.

【解析】【分析】本文是一篇说明文，介绍了大熊猫的肠道细菌可以帮助他们吸收竹子中的营养。
【点评】本题考点涉及细节理解，词义猜测，推理判断和主旨大意四个题型的考查，是一篇科普类阅读，要求考生在捕捉细节信息的基础上，进一步根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。
9．考查细节理解。根据第二段中的“Their gut (肠道) bacteria change in late spring and early summer when bamboo is at its most nutritious — while protein-rich green shoots are coming out. The bacteria make the panda gain more weight”它们的肠道细菌会在春末夏初发生变化，此时正是竹子最富营养的时候——富含蛋白质的嫩芽正在长出来。这种细菌使熊猫增加更多体重。可知，大熊猫在春末和夏初的时候会增加更多体重。故选A。
10．考查词义猜测。根据第三段中的“We've known these pandas have a different set of gut microbiota during the shoot-eating season for a long time, and it's very obvious that they are chubbier during this time of the year”我们已经知道，这些大熊猫在食笋季节有不同的肠道微生物群，很明显，它们在每年的这个时候都是更胖的，可知，chubbier是形容词，用来描述大熊猫在食笋季节的一个特点；以及第二段中的“Their gut (肠道) bacteria change in late spring and early summer when bamboo is at its most nutritious — while protein-rich green shoots are coming out. The bacteria make the panda gain more weight.”它们的肠道细菌会在春末夏初发生变化，此时正是竹子最富营养的时候——富含蛋白质的嫩芽正在长出来。这种细菌使熊猫增加更多体重。可知，大熊猫在春末和夏初的时候会吃很多的笋，体重会增加更多，所以chubbier应该是“更胖的”意思。故选D。
11．考查推理判断。根据第五段中的“Researchers found the mice which were transplanted with panda wastes collected during shoot-eating season gained significantly more weight than the ones which were not, despite consuming same amount of food.”研究人员发现，尽管摄入了相同数量的食物，但是在吃笋季节收集到的熊猫粪便移植到小鼠身上的小鼠比没有移植的小鼠体重增加明显的多。可知，熊猫粪便对小鼠的体重有很大的影响。故选C。
12．考查主旨大意。根据第一段“Pandas are famously picky eaters. They only consume bamboo — a poor quality diet low in fat. But the creatures appear to have evolved to get the most out of what they do eat, according to a new study.”熊猫是出了名的挑食者。它们只吃竹子——一种低脂肪的劣质食物。但是根据一项新的研究，这种生物似乎已经进化到能从它们的食物中获得最多的东西；以及第二段“Their gut (肠道) bacteria change in late spring and early summer when bamboo is at its most nutritious — while protein-rich green shoots are coming out. The bacteria make the panda gain more weight and store more fat, which researchers said may compensate for a lack of nutrients later in the year, when bamboo plants have only fibrous leaves to chew. ”它们的肠道细菌会在春末夏初发生变化，此时正是竹子最富营养的时候——富含蛋白质的嫩芽正在长出来。这种细菌使熊猫增加更多体重，储存更多脂肪，研究人员说，这可能弥补今年晚些时候营养物质的缺乏，因为那时竹子只有纤维叶可以咀嚼。可知，这篇文章主要讲述影响大熊猫营养吸收的肠道细菌。故选B。

At first glance, it seems that giant pandas (大熊猫) might not be good at hide- and-seek. With their black and white coats, they appear to have a hard time matching their backgrounds and avoiding detection by their enemies. But a new study finds that the unique markings, in fact, provide effective camouflage (伪装) and help them disappear into their surroundings. Scientists have long wondered what function the black-and-white coloring plays.
For their study, researchers analyzed photos of giant pandas in their natural habitats. "We've found that the animals are very well camouflaged because they use habitats with dark and lighting conditions, and also snow during some time of the year," study author Tim Caro of the University of Bristol and the University of California, Davis, tells Treehugger.
They found that the black patches (块) of fur match primarily shade and dark tree trunks. They also match the ground, rocks and leaves. The white fur patches match snow, rocks, and waxy, bright leaves. Sometimes pandas also have patches of pale brown fur and those match rocks, ground and shady background areas.
The researchers also explored a type of environmental camouflage known as disruptive coloration. That's when highly contrasting patterns or very visible boundaries on an animal break up its body outline. They found that the black and white borders on the panda's coat make it less noticeable, particularly from farther away.
It might seem a bit confusing because giant pandas are very easy to spot at a zoo, for instance. But the environment and the viewer make a difference.
"We modelled their coloration through enemies' eyes as well as how humans see them so we are sure of the results." Caro says.
"It seems that giant pandas appear easily noticeable to us because of short viewing distances and unnatural backgrounds, when we see them, either in photographs or at the zoo, it is almost always from close up, and often against a backdrop that doesn't reflect their natural habitats," says author Nick Scott-Samuel of the University of Bristol. "From a more realistic enemy's view, the giant panda is actually rather well camouflaged."
13．What is the general first impression of giant pandas
A．They like staying away from humans.
B．They are really good at hide-and-seek.
C．They match the backgrounds very well.
D．They can be easily detected by enemies
14．What does the underlined word "They" in paragraph 3 refer to
A．Tree trunks. B．Pale brown pandas.
C．Black fur patches. D．Shady background areas
15．What can we learn about giant pandas from Nick Scott-Samuel's words
A．They are less noticeable in natural environments.
B．They can be easily noticed even from farther away.
C．They often disappear into backgrounds in a zoo.
D．They can not camouflage from an enemy's view.
16．What can be a suitable title for the text
A．Giant Pandas Hide Themselves From Tourists
B．Giant Pandas Are Actually Good at Camouflaging
C．The Black-and-white Coloring Proves Appealing
D．You Are More Likely to Spot Giant Pandas in Nature
【答案】13．D

【解析】【分析】本文是一篇说明文，研究表明，大熊猫实际上很擅长在自然环境中伪装，从而避免被敌人发现。
【点评】本题考点涉及细节理解，代词指代，推理判断和主旨大意四个题型的考查，是一篇科研类阅读，通读全文，理解文章大意，阅读题目后返回原文阅读并找出与题目相对应的内容，仔细核对，选择符合原文原意的答案，完成后再次阅读并检查。
13．考查细节理解。根据第一段中的"At first glance, it seems that giant pandas (大熊猫) might not be good at hide- and-seek. With their black and white coats, they appear to have a hard time matching their backgrounds and avoiding detection by their enemies."乍一看，大熊猫似乎不擅长捉迷藏。由于它们的黑色和白色外套，它们似乎很难与背景相匹配，避免被敌人发现。可知，对大熊猫的第一印象是它们很容易被敌人发现。故选D。
14．考查代词指代。根据第三段中的"They found that the black patches of fur match primarily shade and dark tree trunks. hey also match the ground, rocks and leaves."他们发现，皮毛的黑色斑块主要与阴影和深色树干相匹配。它们还与地面、岩石和树叶相匹配。可知，画线词 They 指代上文提到的"黑色斑块"。故选C。
15．考查推理判断。根据最后一段中的"‘It seems that giant pandas appear easily noticeable to us because of short viewing distances and unnatural backgrounds, when we see them, either in photographs or at the zoo,it is almost always from close up, and often against a backdrop that doesn't reflect their natural habitats,' says author Nick Scott-Samuel of the University of Bristol."布里斯托尔大学的作家尼克·斯科特-塞缪尔说："由于近景和不自然的背景，我们似乎很容易注意到大熊猫。当我们在照片或动物园看到它们时，几乎都是近距离观察，而且背景往往与它们的自然栖息地不符。"可推断，大熊猫在自然环境中是不太容易被发现的。故选A。
16．考查主旨大意。根据第一段中的" But a new study finds that the unique markings, in fact, provide effective camouflage (伪装) and help them disappear into their surroundings. "但一项新的研究发现，这些独特的标记实际上提供了有效的伪装，并帮助它们消失在周围环境中。可知，本文主要介绍了一个研究发现大熊猫实际上很擅长在自然环境中伪装。故选B。

Are Bamboo-Eating Pandas
Really Herbivores
On
the outside, giant pandas look like herbivores (食草动物).
They spend nearly all of their waking hours eating bamboo. But on the inside,
they're built like carnivores (食肉动物). About half of the
calories they eat come from protein, according to a new study.
The
ancestor of giant pandas were omnivorous(杂食的).
They are both animals and plants, and had the digestive system and gut bacteria
to metabolize(使发生新陈代谢)them. They had "umami taste
receptors," to appreciate the flavors of meat.
However,
about 2.4 million years ago, things began to change. Their jaw and
teeth evolved to help them crush bamboo, and their wrist bone became capable of
grasping the stalk(杆)of their favorite plant.
Scientists think pandas switched to eating bamboo partly because they didn't
have to fight with other animals to get it. Bamboo is high in fiber but has a
low concentration of nutrients, so pandas have to eat 20 to 40 pounds of the
plant every day just to get by.
David
Raubenheimer, a nutritional ecologist at the University of Sydney, and his
colleagues put GPS trackers on two giant pandas and followed their movement
throughout the year. They discovered that the pandas followed the protein.
At the start of the cycle, they ate Bashania fargesii leaves until
they got the chance to feast on young shoots, which contained more protein.
The
more the shoots grew, the more their protein was diluted(冲淡)by fiber. That caused the pandas to move to higher ground, where
Fargesia qinlingensis grew. First, they ate the shoots, but these, too, went
from being protein - rich to fiber-rich as they grew. The panda responded by
switching to the leaves. The researchers found that about half of the
calories the pandas ate were in the form of protein.
"They can know exactly where to go, and when to go, so they can get the
most of the nutrients that their ecosystem can provide," said Silvia
Pineda - Munoz, who was not involved in the study.
The
work also shows that classifying an animals as herbivore or carnivore is more
complex than one might sassume. "It's not whether you're eating plants but
what of the plants you're eating," said Pineda - Munoz.
【答案】D；A；E；B
