The spider monkey has long, thin arms with hook-like hands that allow it to swing (摇摆) through the trees. It has a prehensible (缠绕性的) tail, which means it can grasp and can be used like a     1    (five) leg to grab trees. During the day, the spider monkey searches     2     fruits, which make up the main part of its diet. They will also eat flowers, seeds, leaves, and small insects during the dry season     3     fruits aren’t available. They spend most of the daylight hours climbing and swinging through the high branches of trees.

The brown-headed spider monkey lives in a large community of about 20 to 100 male and female monkeys. Females     4    (normal) give birth to only a single baby each year or two. Young monkeys are carried on their mothers’     5    (stomach) until about 16 weeks old. Then they are strong enough     6    (ride) on their mothers’ backs.

Spider monkeys hug each other and wrap their tails around each other. They are very     7    (intelligence) and have strong memories. They are named spider monkeys     8     they look like spiders as they hang upside down from their tails with their arms and legs     9     (swing).

Now hunting the brown-headed spider monkey is forbidden in Ecuador,     10     country in northwestern South America, but humans have killed them for their meat for hundreds of years.

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.

4 . If you walk into a native plant nursery, you must feel defeated because all the little plants look similar. Now we have the shopping guide for you: a set of easy-to-carry flashcards that explain in brilliant color what those little plants will look like when they all grow up.

Native plants just aren't that easy to understand for traditional gardeners. “That's why staff at the Theodore Payne Foundation for Wild Flowers & Native Plants began creating some good information into the world of native plants," said Kitty Connolly. "Everybody needs to learn about natives if we're going to have them, in our future, but it's difficult to get information to everyone at once. We wanted something that would be useful to everyone. "

The group decided to create flashcards only about the size and shape of an iPhone 6. “You can take them apart and put them on a table to see how plants go with other plants. They don't replace a website or great books on the shelf; they're just easier to carry and use for planning, said Mike Evans. While the cards are very small, they include a lot of information. You can find how tall and wide a particular plant will grow, when it blooms, how quickly it grows, what birds and animals it attracts and how much water and sunlight it needs.

The cards don't include all native plants. They don't include milkweed, for example. But they are helpful for people to learn native plants.

The price of the cards is $ 17. They are only sold online. If people have the cards , they can more easily request the plants they want. The director said, “We create the cards with the hope that people can learn more about native plants and grow them."

1. Why do people feel defeated in a native plant nursery?

A．They can't recognize little plants there.	B．The little plants are difficult to carry.
C．The little plants have bright colors.	D．They're forced to buy many plants.

2. How does Mike Evans like the flashcards?

5 . Jack was born without eyes. He was very lucky as he grew up having other kittens(young cats) to socialize with, and was used to people from the moment he was born. However, when it came time to find the kittens homes, no one knew where Jack would end up.

That's when I got an email from my friend. All she asked was “Do you still want one of the kittens? There's one here with no eyes and no one would like to take him.” Without thinking, I told her that I did want the kitten.

When we first brought him home, Jack stayed mostly in my room. After about a day he had no issues running around and climbing on everything. At times he gets lost in the house, he'll stop. But we just call him and talk to him and it isn't long before he finds his way back to us.

A few weeks after getting Jack, we got a new farm cat named Bear. Jack and Bear have   become best friends. It doesn't matter that he can't see. He always knows when Bear is around. He'll run across the yard straight to Bear and wrap his front legs around his neck in a big hug. They run after each other around and wrestle. They'll lie down in the grass together when tired.

Jack is truly an inspiration. I've owned lots of kittens in my life, but Jack is the happiest and most playful. He doesn't feel sorry for himself. He doesn't need pity. I think Jean, owner of Gumbo, another eyeless cat, said it best when she told me that cats don't have disabilities, they have adaptability.

1. Why did Jack come to our home?

A．I liked an eyeless cat.	B．I didn't mind whether he was blind.
C．No other young cats kept him company.	D．My friend ordered me to take him home.

2. What does the underlined word “issues” in the 3rd paragraph mean?

A．Difficulty.

B．Fun.

C．Luck.

D．Business.

3. Which of the following statements is TRUE?

A．Jack likes to play with a new eyeless cat.

B．Jack is good at talking and playing with people.

C．Jack quickly adapts to the new environment.

D．Jack and Bear lie down on the sofa together when tired.

4. What can we learn from the passage?

A．A cat has nine lives.	B．All is well that ends well.
C．God helps those who help themselves.	D．A good beginning makes a good ending.

6 . Most people feel that dreams are unique to humans, but many dog owners will likely disagree. They have noticed that their dogs at various times during the sleep may shake legs, snort (哼) and sometimes growl (低声吼叫) which gives the impression that they are dreaming. These things may wonder us about whether dogs dream.

Scientists confirm that dogs probably do dream. It turns out that dog brains and human brains have many similarities during sleep cycles. Researchers used special machines to measure electrical activity in a dog’s brain and a human’s brain. Scientists already knew that when humans dream, a certain part of the brain is active during sleep. Researchers discovered that the same part of the brain is active in sleeping dogs. Scientists have other data that back up these findings.

Many people dream that they are trying to move but cannot. Interestingly, part of that experience is not a dream. When people sleep, the brain produces a chemical that causes the dreamer to become temporarily paralyzed (使麻痹). Researchers think this happens so that people cannot physically act out dreams while they are sleeping. Dog brains make the same chemical. In one study during which this chemical was blocked, sleeping test dogs performed physical activities, such as standing up, sniffing around the room for imaginary rabbits, or chasing imaginary balls.

Because of these similarities, researchers believe that the content of a dog’s dream might come from the same source as a human’s dream. “People’s dreams are usually based on things they did that day,” says Dr. Samantha Hudspith. “So we have reasons to believe that dogs dream about the things they’ve done that day. Of course, there will never be a way to prove this. Dogs cannot describe their dreams the way that humans can.”

1. Which statement is TRUE?

A．Only humans dream.

B．The dogs’ shaking legs during the sleep means that they must be dreaming.

C．The contents of dogs’ dream is the same as those of humans.

D．Whether dogs dream of the things they’ve done that day can not be confirmed.

2. What happened to a sleeping dog when this chemical mentioned in paragraph 3 was cut off?

A．It woke up.	B．It stopped dreaming.
C．It acted out its dream.	D．It couldn't move its body.

3. Where is the passage from?

A．The guide

B．The report

C．The magazine

D．The brochure

7 . Nougat and Clarence became best friends almost as soon as Nougat moved into the retirement home. Nougat likes to rest his head on the back of Clarence as often as he gets the ____. The dogs live at Vintage Pet Rescue, a non-profit organization that ____ elder animals from local shelters (收容所) that are ____ to find a new home. The organization aims to give dogs a comfortable, loving environment at the ____ of their lives.

Kristen Peralta, the founder of Vintage Pet Rescue, takes care of 27 mostly senior dogs. While she and her husband have unofficially been ____ older dogs for some time, Peralta turned her passion into a full-time job in 2017.

In some ways, elder dogs may be less ____ to care for because they prefer sitting still than little ones. But their futures aren’t always so ____. There are many organizations, like Peralta’s, ____ on rescuing elderly pets and giving them protection outside of animal shelters, in part because senior dogs in shelters have a(n) ____ rate of just 25 percent, while younger dogs have a 60 percent rate.

A life spent ____ two dozen older dogs can be very busy. Peralta ____ vet appointments at least once a week, gives out individual medications and does a lot of bathing and petting. But the work is rewarding, and she thinks it’s helping to show more and more people are beginning to ____ just how special senior dogs are. “You can just tell how much they ____ it when they’re helped in trouble,” Peralta said. “They’re ____ that they’re with you and you love them. It’s so special to know that you saved a dog’s life and that you’re going to make a ____to the rest of its life.”

8 . 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.

9 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

Catherine Svilicic never would have guessed her adopted rescue clog Khan would act out with aggression (攻击性) towards her young 17-month-old baby, Charlotte!

The day began with the usual playtime outside. Although baby Charlotte had her parents watching from a distance, they did not notice anything out of the ordinary. Charlotte and the new dog had been making a habit of playing like this. However, things were different that day. Catherine watched as Khan threw her baby across their backyard! Why was Khan acting as though a lovely child was a threat? Catherine watched him drag her child, hoping he would stop. Sadly, it seemed Catherine needed to immediately intervene because this was only the beginning. He tightly clenched his jaws (咬紧牙关) into her diaper (纸尿裤) to throw her back and forth. This is when things got out of hand. Certainly, Catherine was angry with Khan for throwing her girl. However, something deep down told Catherine there was more to this than what they were seeing. Little did she know, these doubts would turn out to be true.

But her baby was still in great danger. Catherine noted that her baby seemed a target. That moment we mentioned when the dog sunk his teeth into Charlotte’s diaper and used his strength to throw her baby like “a doll”. How terrifying! Luckily, those teeth did not go near her skin and especially face and the baby was actually quite calm. Perhaps, the baby understood something about Khan’s intentions.

Catherine knew that she needed to act fast and catch her poor child. Something happening to Khan next that confused the whole family.

While the baby stayed calm, others could not help but panic. Charlotte’s mother said, “Had I not seen it with my very own eyes, I’d never have believed it.” Therefore, she ran to Charlotte and carried her to safety.

While Catherine brought her baby to shelter, Khan barked madly and then fell down.

10 . Plants: we eat them, juice them, weave them — and now it seems we can mine them too!

After a successful experiment on the island of Borneo, Botany Professor Alan Baker and a group of researchers want to introduce phytomining (harvesting minerals from plants) as a better, partial substitute for traditional mining.

Phytomining means collecting metal from live plants. However, this can only be done with a group of plants known as “hyperaccumulators.” They naturally attract and absorb minerals through their roots and then store huge, pure concentrations of these minerals in their bodies. The metal can then be extracted from the plant’s sap (液), oil, or sometimes even live tissue.

The term “phytomining” was coined in 1983 by Rufus Chaney of the US Department of Agriculture, who had worked with Baker in early phytomining experiments. But the idea of plant-mining was actually thought of 500 years ago by German scientist Georgius Agricola, who smelted leaves to identify the metals underground.

Baker and his colleagues see a lot of potential in phytomining. Not only can it help meet the growing global demand for metals, but is also a way of undoing some of that damage to the environment by traditional mining.

One of the biggest problems with traditional mining is that it pollutes the surrounding area. Phytomining can extract that metal waste, plus planting the hyperaccumulators would regrow the deforested areas created by mining operations.

Aside from this, if phytomining is able to replace part of traditional mining, then there would be fewer instances of bad mining practices like abandoned mines, which pollute the nearby waters. Also, since phytomining provides metal that is already naturally pure, there is no need to use huge amounts of energy to purify the ore (矿石).

However, phytomining has its drawbacks. Harvesting plants on a large scale is expensive today, compared to traditional mining. Besides, plants can be wiped out by diseases or unexpected weather conditions.

However, there are many reasons to consider phytomining. It gives us the hope that our advancement doesn’t mean sacrificing Mother Earth.

1. What makes hyperaccumulators different from other plants?

A．The ability to take in and store metals.

B．The ability to process various nutrition.

C．Their roots deep through the earth.

D．Their oil extracted from live plant tissue.

2. Which is the disadvantage of phytomining?

A．It can pollute the nearby area.

B．It can waste huge amounts of energy.

C．It can do harm to our climate.

D．It can be affected by bad weather.

3. What can we learn about phytomining?

A．The term came up even 500 years ago.

B．Its potential mainly lies in lower cost, compared to traditional mining.

C．It can make up for the damage caused by traditional mining.

D．It uses clean energy sources to purify the ore.

4. What is the best title for the passage?

A．Future of phytomining	B．Metals from plants
C．Solutions to pollution	D．Experiments on plants
