The Wolong Panda Reserve Research Center was set up in 1958    1    （save） the declining panda population. The Panda Reserve is a three-hour drive from Chengdu. It’s a natural reserve    2    （cover）over 200,000 hectares. As    3    （large） panda reserve of all in China, Wolong    4    （add）to UNESCO in 1980.

In 2003 Wolong Panda Reserve opened up wildlife observation areas, and it    5    （attract）over 100,000 visitors each year. The Wolong Giant Panda Reserve is also home to other rare and endangered wild animals such as the golden monkey, red panda, and more.

The Giant Panda is    6    （usual）classified in the bear family, and is native to central and southern China. Pandas’ main food is bamboo, but they also eat foods such as fish, eggs, and honey.

Adult pandas have a    7    （long）of 1.6m to 1.8m, and weight between 176 to 275 pounds. Giant pandas have a large head    8    obvious black patches around the eyes, ears, and the body.

Giant pandas are found in mountainous regions    9    are thick with bamboo trees in Sichuan and Tibet. Pandas reproduce very slowly, and infant mortality（死亡率）is high---these are major reasons why it’s such    10    endangered species.

2 . I love snakes. My mom definitely does not. When she was a kid, snakes used to hide in warm spots under the furniture. So she grew up afraid she’d step on a snake. I grew up hoping I’d see one... outside! Lots of people who are afraid of snakes have never even seen one. So where does our fear come from?

Scientists wonder about this too. Their experiments with adults, kids, and even babies show that it’s complicated. People may not be born afraid of snakes, but we are born able to see them quickly. In tests with pictures, people picked out snakes faster than they could find flowers, frogs, and caterpillars. It wasn’t just snakes, though. People also found spiders and angry faces faster than “safe” things like flowers. It seems like we find things that might be dangerous to us faster than things that aren’t

People also learn to fear snakes faster than we learn to fear many other things. We take our hints from other people’s scared voices and faces. Some scientists think we’ve evolved this way—faster to see snakes and faster to learn to fear them. After all, if we had to be bitten by a snake to learn that it’s dangerous, we might learn our lesson too late.

So why does it matter if we’re afraid of snakes? It may not matter much to us, but it matters to snakes. People protect animals they like, not animals they fear. Snakes may not be as cute as dolphins, but they’re just as important to the environment. Snakes eat insects that are pests to humans. Snakes are also food for other animals, so when we kill snakes, we’re hurting other creatures too.

How do we get past our fears to give snakes a chance? Scientists did a study recently where students of your age went on a field trip, Guides helped them find and capture snakes in the forest. Everyone could safely touch and hold a snake. It turns out that snakes aren’t so bad when you get to know them. Most people who were afraid of snakes before the field trip weren’t afraid afterward. In fact, snakes even became some students’ favorite animal. Hmm, maybe I should take my mom on the next field trip.

Remember：Always respect snakes, whether you’re afraid of them or not.

3 . This summer, a cave in Central Europe got a lot of attention when it became home to more than two dozen baby dragons. These animals are actually called olms (洞螈) which look like dragons.

A female olm might lay eggs just once every six years. Excitement over the possibility of new babies started in January, when the first egg was spotted deep within the Postojna Cave in Slovenia. In the end, with the help of scientists, 22 olms were born between May 30 and July 14. They are now growing into healthy teenage dragons.

Olms live in underwater limestone caves in Central Europe. These caves are difficult to reach, so scientists don’ t often get to observe olms in their natural habitat.

Olms, which can grow to be up to 16 inches long, are one of the largest cave animals in the world. They have pale skin and long snouts and their tiny eyes are fully covered with skin.

No natural light reaches these deep caves, so many animals that live there cannot see. But olms use their incredible senses of smell and hearing to hunt worms, crabs, and snails. Olms can also survive without food for long periods of time, even as long as 10 years.

When a female olm laid 64 eggs in the Postojna Cave last winter, scientists thought that only two or three of them would survive. In the wild, only about two baby olms successfully hatch from 500 eggs. The last time a female olm laid eggs at the Postojna Cave, none of the eggs hatched. So this time, scientists worked very hard to care for the olm eggs and watched over them as they grew. About one-third of the 64 baby olms survived, and they appear to be doing well.

Scientists are hopeful about the babies’ future. Although baby olms don’ t eat for the first couple of months, by August three of the oldest babies were eating worms. That was an important step in their development.

“We will keep doing everything we possibly can to ensure the olms’ well-being,” a press statement for the team stated.

1. What can we learn about the birth of the olms found in the Postojna Cave this year?

A．It is an extremely rare event.	B．It proves dragons really exist.
C．It needs more public attention.	D．It means a new-found species.

2. What is a characteristic of olms?

A．They prefer living in dry environments.	B．They have a poor sense of hearing.
C．They can live up to 10 years.	D．They are born blind.

3. What do the numbers in Paragraph 6 show?

A．Olms can’ t live without scientists’ help.

B．The birth rate of olms is usually very low.

C．Olms usually face hard living surroundings.

D．Fewer and fewer female olms lay eggs now.

4. How old were the oldest baby olms when they began to eat this summer?

A．Less than one month old.	B．Over two months old.
C．Nearly twelve months old.	D．About eight months old.

4 . Researchers say they have translated the meaning of gestures that wild chimpanzees (黑猩猩) use to communicate. They say wild chimps communicate 19 specific messages to one another with a “vocabulary” of 66 gestures. The scientists discovered this by following and filming groups of chimps in Uganda, and examining more than 5,000 incidents of these meaningful exchanges.

Dr Catherine Hobaiter, who led the research, said that this was the only form of intentional communication to be recorded in the animal kingdom. Only humans and chimps, she said, had a system of communication where they deliberately sent a message to another group member.

“That’s what’s so amazing about chimp gestures,” she said. “They’re the only thing that looks like human language in that respect.”

Although previous research has shown that apes and monkeys can understand complex information from another animal’s call, the animals do not appear to use their voices intentionally to communicate messages. This was a significant difference between calls and gestures, Dr Hobaiter said.

Chimps will check to see if they have the attention of the animal with which they wish to communicate. In one case, a mother presents her foot to her crying baby, signaling: “Climb on me.” The youngster immediately jumps on to its mothers back and they travel off together. “The big message from this study is that there is another species (物种) out there. that is meaningful in its communication, so that’s not unique to humans,” said Dr Hobaiter.

Dr Susanne Shultz, an evolutionary biologist from the University of Manchester, said the study was praiseworthy in seeking to enrich our knowledge of the evolution of human language. But, she added, the results were “a little disappointing”.

“The vagueness of the gesture meanings suggests either that the chimps have little to communicate, or we are still missing a lot of the information contained in their gestures and actions,” she said. “Moreover, the meanings seem to not go beyond what other animal convey with non-verbal communication. So, it seems the gulf remains. ”

1. What do chimps and humans have in common according to Dr Hobaiter?

A．Memorizing specific words.	B．Understanding complex information.
C．Using voices to communicate.	D．Communicating messages on purpose.

A．It was well designed but poorly conducted.

B．It was a good try but the findings were limited.

5 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

A number of white cranes (鹤) have been spotted at Poyang Lake in Jiangxi province,     1     (mark) the start of the migratory (迁徙的) birds’ wintering in China’s     2     (large) freshwater lake this year.

At 10:45 am, October 29, 2020, one white crane     3     (observe) at the lake. Another 17 were spotted at 2:30 pm, according to staff with the Jiangxi Poyang Lake National Nature Reserve Administration.

Apart from white cranes, white-naped cranes, grey cranes, oriental white storks,     4     other species of migratory birds have also arrived at the lake.

White cranes are also known as “living fossil” birds,     5     only about 4,000 in the world. Every year at the end of autumn and the beginning of winter, they fly to the lake for the winter, aiming     6     (search) for food in shallow water. From late February to early March the following year, a large number of birds begin to fly to the     7     (north) part.

Poyang Lake is an important wintering area     8     (natural) for waterbirds in Asia. More than 300 migratory birds from Russia, Mongolia, Japan, and the Democratic People’s Republic of Korea, as well as China’s northwest and northeast     9     (quarter) have their flocks (鸟群) to winter at the lake each year, of     10     115 are waterbirds, accounting for about 51% of the country’s waterbirds.

6 . As a species,ginkgo(银杏）trees, which enjoy a reputation as "The Tree that Time Forgor", have existed relatively unchanged for 200 million years.While scientists have revealed the mysteries of the tree's long life, it won't help humans soon.

Scientists in China examined the genetic component of very young ginkgo trees,comparing samples between several hundred and a thousand years old.    1    The scientists also found that, unlike other plants, ginkgo genes with regard to aging do not automatically become active at a certain stage in their life cycle.    2    This explains why old ginkgo trees produce as many seeds as young ones and how they continue to grow wide for as long as they live.

Furthermore,ginkgo trees are born with protective biochemical characteristics,in the form of hormones, antioxidants, and bactericides.    3    Also, they have evolved adaptations that enable them to resist pests and climate extremes.

    4    Over time,weather and other factors limit upright growth and cause leaves to die.Yet,even as this aging occurs, the cell-reproducing system of the gingko tree remains active, maintaining healthy growth.Growth typically starts slowing down after 200 years, but the trees remain healthy.Each year, they renew their parts, adding new wood,leaves, roots, and reproductive organs.In theory,gingko trees should live forever.    5    

A．Of course,these trees do age, to some extent.

B．Their immune systems were found to be similar.

C．That is, ginkgo trees have no genetic program for death.

D．All of these strengthen their resistance to diseases and bacteria.

E．While they contain minor poison, humans still eat their fruits for health reasons.

F．However,ginkgo trees still die from pests,drought,and other damaging events.

G．They have survived some greatest catastrophes, such as the extinction of the dinosaurs.

7 . Corals are often described as undersea forests, but they are declining far more quickly than the Amazon. The coral reefs( 珊 瑚 礁 )are likely to be among the first ecosystems to be wiped out by climate change.

A temperature rise of just 1 to 2℃ can lead to the death of the algae( 海 藻 ) upon which corals depend, draining them of color and making the structure more fragile. These bleaching( 褪 色 的 ) events can be temporary if waters cool, but the more frequent they are and the longer they last, the greater the risk of damage is.

But that’s exactly what is happening. Bleaching was first observed in 1983. It was seen on a   global level in 1998, then 2010, and then from 2015 to 2017. Most available scientific evidence tells us that unless we do something to limit warming to 1.5℃, we will lose 99% of the world’s coral reefs in coming decades.

But there are other threats beyond warming. Off the Philippine island of Palawan, its old reefs have been badly damaged by dirty water from the tourist holiday center, pollution from boats and overfishing. The area ought to be a shelter because it’s one of the ocean regions most tolerant of climate change. “Even here, we are losing our corals,” said David Obura, chair of the Global Specialist Group in the International Union for the Conservation of Nature. “We need to reduce stress from overfishing, coastal development, pollution and tourism.”

“I am a generation of scientists watching them disappear. It is very depressing.” Obura said. “Above 1.5℃, in about 50 years, they will be a treasure of historic movies and pictures, but very little to see in real life. Children born today may be the last generation to see coral reefs in all their glory.”

1. The rising temperature affects corals by .

A．darkening their color

B．harming their structure

D．Global warming

4. What can be a suitable title for the text?

A．Experts worry about global warming.

B．Philippine coral reefs are under threat.

C．Record undersea forests before it is too late.

D．The next generation may never see coral reefs.

8 . With more than two million videos on YouTube, cats are one of the most searched things on the Internet. A new exhibition called “How Cats Took Over The Internet” opened at the Museum of the Moving Image in New York. It looked at the history of how cats rose to Internet fame, and why people like them so much.

Almost half of all original YouTube videos are of people ’s pets, and around 26 billion views are just for cats, making them the single most popular category. Some cats have become famous and earned millions of pounds after their owners posted their pictures online.

So how did cats become so popular?

Since the Internet became widely used in the 1990s, people have been sharing pictures of their cats via email. In 2005 one of YouTube’s co-founders Steve Chen posted a video of his cat called Pyjamas playing with a rope, making him the first person to upload a cat video to YouTube.

In 2007 Eric Nakagawa and Kari Unebasami started a website sharing funny pictures of cats, The site quickly became popular, and users were able to upload pictures of their cats with writing over the top. It now has over 100 million views a month and has created a whole new form of communication on the Internet.

Why cats? A scientific study has proved that looking at videos of cats can improve people's mood. Assistant professor Jessica Gall Myrick from Indians University, America, asked 7,000 people how they felt before and after watching videos of cats. The results showed that people felt happier after watching videos of cats, and that they felt less anxious.

The Internet has also been responsible for creating a number of famous cats such as Grumpy Cat, Lil BUB and Maru. They have appeared on lots of TV shows, advertisements and film festivals, and even have their own brands. Lil BUB even has her own charity, and has raised around $130, 000 for pets with special needs.

1. What’s true about cats according to the text?

B．Cat videos take up half of all the original YouTube videos.

C．They are the first to be filmed among all the animals throughout the world.

D．They earned millions with their videos in the 1990s.

2. Why did Jessica make the study?

A．To improve people's mood and reduce people's anxiety.

B．To ask about people's present feelings and living conditions.

C．To find the effect of watching cat videos on people's mood.

D．To help people live their life to the fullest.

3. What’s special about Lil BUB?

A．She has the most videos online.	B．She is popular at home and abroad.

9 . Twenty years ago, I became involved in pet therapy (治疗) work. As digging deeper into the job, I had an urge to be a recorder of their daily work to let more and more people know their efforts and contributions. After all, they could not say our languages. It was when I got familiar with the work that I got my golden retriever puppy (金毛寻回犬), whom I named Angel. As she matured and went through obedience training, I realized that she would be a good partner.

Angel is ten now and still works every week. As a rule, she visits two hospitals, a day care for the elderly, and our library’s PAWS for Reading program. Angel has also helped out at a children’s special-needs camp. She is so popular that everywhere we go people recognize her, especially the kids she has worked with.

We have seen some very special things through our pet therapy work. I brought Angel to our local hospital to visit a woman who was completely paralyzed (瘫痪的) on her right side from a stroke. One day, my husband, Jack asked her if she wanted to give Angel a treat. She nodded and gently took the treat, raised her right hand and started petting Angel. Her friend was in the room and said, “She hasn’t been able to move that hand since she had her stroke!”

Somehow it seems appropriate that when Angel visits the hospital, she also performs tricks for the patients with her paws. The best one is when she crouches on the floor and crosses her paws. She stays still and doesn’t move until Jack says “Best wishes”. It’s the best wishes for all the people Angel meets as well as for her.

C．She gave her best wishes.	D．She played tricks on her.

4. What is the best title for the passage?

A．A loyal dog.	B．Selfless love.
C．A silent angel.	D．Great devotion.

10 . Every year, many dolphins worldwide are captured（捕获）and kept in small pools, performing for people, especially children. These dolphins are fed fish instead of having to_________them.
