2 . The Hanging Gardens of Babylon, one of the Seven Wonders of the Ancient World, is perhaps the earliest and most famous example of botanical gardens. Over decades and centuries, many incredible botanical gardens have been established. Here is a list of them.

Orto Botanico di Padova

The Orto Botanico di Padova in Padua, north-eastern Italy, is the oldest academic botanical garden still in its original location. It was founded in 1545 by the Venetian Republic. It is spread across an area of 22,000 square meters. It is particularly known for its historical architecture, as well as the collection of 6000 kinds of plants. The astonishing botanical garden is a UNESCO World Heritage Site.

Kirstenbosch National Botanical Garden

The Kirstenbosch National botanical Garden is located at the foot of Table Mountain in. Cape Town, South Africa. It is one of South Africa's nine national botanical gardens, which covers five out of six biomes (生物群落)，and the first of its kind in the world. It is famous for exhibiting native plants from different regions.

Botanical Garden and Botanical Museum

The Berlin-Dahlem Botanical Garden and Botanical Museum is located in Berlin, Germany. It has 22,000 different plant species. Among its different plants is a giant bamboo. This astonishing garden has a large scientific library attached to it. The complex has buildings and glasshouses.

Singapore Botanic Garden

The 74 hectare (公顷)Singapore Botanic Garden in Singapore is the only botanic garden that stays open from 5 am to 12 midnight, every day.

3 . Scientists have been surprised and impressed with the long-distance travel of two birds recently, a common cuckoo which flew from southern Africa to Mongolia, and an eastern curlew, which flew from Australia to China.

On one is a common cuckoo. It's one of 5 cuckoos who were tagged last summer in Mongolia? far to the north of China.     1     However, scientists weren't sure that cuckoos from Mongolia flew to Africa for the winter.

In June, 2020, scientists attached tiny trackers to five cuckoos.     2    Sure enough, Onon spent the winter in southern Africa — in Zambia.

    3     “It was one of the longest animal migrations which has been recorded for a land bird.” said Chris Hewson, one of the project s lead scientists.

At times, Onon stopped for a few hours or a few days. But some of the long stretches, like crossing the Indian Ocean, had to be done without stopping.     4     The birds have to travel through strong winds and storms, make sure they find enough to eat, and avoid being eaten themselves.

Luckily, cuckoos seem to have a good sense of weather patterns, allowing them to fatten up as much as possible right before they leave. They also seem to be good at finding helpful winds that allow them to travel long distances without getting too tired.     5     Onon is the only one of the five tagged cuckoos who made it all the way back to Mongolia.

A．All of them grew well.

B．Still, flying such long distances isn't easy.

C．Long migrations like this are dangerous.

D．Cuckoos originally came from Africa.

E．They broke previous records of animal migrations.

F．Long migrations are common among sea birds, but cuckoos are land birds.

G．These trackers allowed the scientists to follow the movements of the birds on a map.

4 . On January 1, the Canadian city of Montreal is set to ban（禁止） the horse-drawn carriages on the street. Jean-Francois Parenteau, a spokesman for the city of Montreal, said "It is a tradition that has long been appreciated. But today, I think it is time to move on." He added that it is important for the city to "care about animals".

His speech was welcomed by Galahad, an organization that seeks to protect horses and had cam paigned（发起……运动） for the ban. Its founder, Chamie Angie Cadorette, said the horses faced hard working conditions.

"It is not just an hour a day. It is eight hours a day to go up and down the roads in traffic. The carriage owners are treating their animals very badly," she said.

"They say the animals are being abused. Prove it," said carriage business operator Luc Desparois. His company, which has 15 horses and employs 15 carriage drivers, recently led a legal battle against the ban and failed.

Nathalie Matte, another carriage operator in the city, said that the carriages had become an important part of Montreal's culture over the years. "They have been around since Montreal started and many people are clearly drawn to the beauty of the horses," he said.

Mujtaba Ali was visiting Montreal while traveling through Canada. "It's a special way to see the city rather than just taking the bus or the subway," he said.

After being pressured by animal rights groups for years, at first the city government had tried to satisfy the animal activists by banning the horses from the streets when summer temperatures rose. But they kept pushing for a total ban. A turning point happened in 2018 when a horse died on the street while pulling a carriage. The incident forced Montreal Mayor Valerie Plante to support the removal of horse-drawn carriages from the city. The ban is expected to put about 50 carriage operators and their horses out of work.

A．The bad treatment of the horses by the tourists.

B．The government's support to remove the horses.

C．The sudden death of a working horse on the street.

D．The traffic problems caused by the horses in the city.

4. What can be learned about the horse-drawn transport in the city of Montreal?

A．It is the best attraction.	B．It is a long-time tradition.

7 . The average American male consumes 100 grams of protein daily — almost double the necessary amount. This overconsumption isn’t able to continue for long. Besides, there’ll be an extra 2.5 billion people by 2050. Therefore, the United Nations will need to increase as many as 70% food projects by 2050 to solve this problem.

To survive, we need to change the way we farm and eat. Experts say algae(藻类植物), which can offer lots of protein, could be a possible solution. Meat, which is our main source of protein, uses a lot of our limited resources, like water and land, not just for the animals but also to grow their food. But the green slimy algae that lives in oceans, ponds and aquariums can grow fast, is packed with nutrition and needs next to nothing to grow. It can even grow in a desert. That’s surely a big deal.

The wellness company iWi is now growing a type of algae on a large scale. The farm has green seas as far as the eye can see. The entire farm covers 900 acres, 98 of which is currently being cultivated and operates all year around.

The algae on the farm is grown in long ponds called “raceways”, and an engine constantly stir water to make sure the algae is exposed to the sunlight. CO₂ and a tiny bit of fertilizer are then pumped into the water to help the algae grow.

The fresh algae grown on iWi’s farm is a far cry from the unpleasant taste in your mind. That’s because not all types of algae smell or taste like pond scum(浮垢). And the farm’s algae simply tastes salty and gives hope that people would willingly eat this.

“The protein we’re producing is not going to be green,” said Miguel Calatayud. “Our protein powders will be difficult to be noticed when added to other foods. It will be in every single food that you eat on an everyday basis. Algae is going to be part of a regular food chain for us. It’s going to be a great thing for all of us and for our entire planet.”

1. Why will the UN need to increase its food projects?

A．To deal with over-population in the world.

B．To double Americans’ protein consumption.

C．To ensure Americans’ 100 grams of protein daily.

D．To solve the possible protein shortage worldwide.

2. What’s the algae’s advantage over meat?

A．It contains more protein.	B．It can grow in the desert.
C．It is much more delicious.	D．It is environmentally-friendly.

3. What does the underlined part in Paragraph 5 mean?

A．Is considered as.	B．Is different from.
C．Is responsible for.	D．Is applied to.

4. We can infer from Miguel Calatayud that the new algae_____.

A．can benefit the demand for protein unconsciously

B．has a surprisingly good effect on people’s health

C．has a different color from the common algae

D．can change the future of our eating habits

8 . There is a huge need for shark fins (鳍) in Asian countries. As a result, many sharks are caught and killed. According to reports, sharks are being killed at an shocking rate (速度) of up to 273 million worldwide every year.

Some experts predict that if the killing continues at the current rate, many shark species will be lost forever. It can be very dangerous. Sharks are very important and they should be protected.

In a study of the east coast of the United States, 11 species of sharks were eliminated from their range. Of the 14 species of ocean life that those sharks used to eat, the populations of 12 exploded and caused great damage to the ecosystem. For example, the cownose ray (鳐) population was no longer kept under control by sharks and so grew out of control. As a result, the rays destroyed the population of bay scallops (扇贝), their favorite food. The scallop fishery, which had been in good condition for over 100 years, was destroyed completely. Also, the removal of the scallops most likely had an effect on water quality as they were no longer there to perform their function (功能) of cleaning the water.

Sharks tend to eat very efficiently (高效地), going after the old, sick, or slower fish in a population, keeping that population healthy. Sharks help keep many populations of ocean life to the right size so that those prey (猎物) species don’ t do harm to the ecosystem by becoming too populated. The ocean ecosystem is made up of very complex (复杂地) food webs. For the most part, sharks are at the top of these webs and are considered by scientists to be “keystone” species, meaning that removing them may cause the whole structure to fall apart. Therefore, we should protect sharks because doing so is to protect the whole ecosystem.

1. According to the passage, in Asian, people kill sharks mainly because ________.

A．sharks are dangerous for people	B．there are too many sharks
C．shark fins are in great need	D．sharks often attack swimmers

2. Which of the following can replace the underlined word “eliminated” in Paragraph 4?

A．Fed.

B．Removed.

C．Charged.

D．Protected.

3. After the number of cownose rays greatly increased, ________.

A．water quality improved as well	B．bay scallops grew out of control
C．there are more food for shark	D．the local scallop fishery was harmed

4. What can we know about sharks from Paragraph 4?

A．They can’t find enough food to feed on.

B．They never eat the old, sick or slower fish.

C．Their large populations can harm the ecosystem.

D．They play a key role in keeping the ecosystem healthy.

9 . You can’t see your sleeping pet’s brain waves, but its behavior can tell you when your cat might be dreaming. If you watch closely, you’ll see that as she falls asleep, her breathing becomes slow and regular with her body still. She has entered the first stage of sleep, called slow-wave sleep. After about 15 minutes you’ll notice a change in her breathing, Her eyes move under her closed lids, her paws twitch (抽动) and she flicks (轻拂) an ear. She has entered dreaming. Although she twitches and makes little grunting noises, messages from her brain to the large muscles in her legs are blocked, so she can’t run about. She is in a state of “sleep paralysis (麻痹)”.

Michel Jouvet, a French scientist, interrupted their sleep paralysis. Even though they were completely asleep, the dreaming cats began to run for balls that Jouvet couldn’t see and arched (成弓形) their backs at unseen enemies. He figured he was watching them act out their dreams! Obviously, the dreaming cats seemed to be practising important cat skills: following, catching, and fighting.

In another study, Matt Wilson recorded rats brain waves while they learned mazes (迷宫). One day, he left the brain-wave-recording machine on while the rats fell asleep. The pattern of brain waves in the sleeping rats matched the pattern from the maze so closely that Wilson could figure out exactly which part of the maze each rat was dreaming about!

Many researchers now think that in both people and animals, one purpose of dreams is to practise important skills and figure out recent learning. This may explain why so many people dream about fighting and escaping, skills that were probably important to our ancestors, and why dreaming affects our ability to learn.

Do all animals dream? From looking at the brain waves of sleeping animals, how often animals dream seems to be tied to body size. Cats dream about every 15 minutes, mice every 9 minutes, and elephants every 2 hours. And though cows and horses usually sleep standing up, they only dream when lying down.

1. What does Michel Jouvet find in his study?

A．The dreaming cats are practising their important skills.

B．The dreaming cats are in a state of body paralysis.

C．The eyes of dreaming cats move while bodies are still.

D．The dreaming cats suddenly wake up and run for the ball.

2. What can you learn from the passage?

A．Dreaming a lot can help humans learn more.

B．Learning mazes is the basic skill for cats to learn.

C．Fighting and escaping are not important skills for ancestors.

D．Rats also dream to work out their recent learning.

3. Which animal may dream most frequently?

A．Dogs.	B．Rats.
C．Cows.	D．Elephants.

4. How does the author develop this passage?

A．By making comparisons.	B．By using figures.
C．By telling stories.	D．By showing facts.

10 . It’s a good thing that sloths (树懒) don’t have to go to school. They’d never make it on time. These sleepy tree-inhabitants sleep up to 20 hours a day! And even when they are awake, they barely move at all. In fact, they re very slow, and algae (海藻) actually grows on their fur.

Sloths live in the tropical forests of Central and South America, With their long arms and hairy fur. they look like monkeys, but they are actually related to anteaters (食蚁兽). They can be 2 to 2.5 feet long and weigh from 8 to 17 pounds, depending on species.

There are two main species of sloth, identified by whether they have two or three claws. (爪子) on their front feet. The two species are quite similar in appearance, with roundish heads, sad-looking eyes, tiny ears, and short tails. Two toed sloths are slightly bigger and tend to spend more time hanging upside down than their three toed cousins, who will often sit upright in the fork of a tree branch. Three toed sloths have facial coloring that makes them look like they’ re always smiling. They also have two extra neck vertebrae that allow them to turn their heads almost all the way around!

Some scientists think sloths developed their slow-motion lifestyle so they would be less noticeable to hunters such as hawks and cats, which rely heavily on their eyesight when hunting. The algae that grows on sloths’ fur also helps them avoid hunters by letting them mix in with green leaves. They rarely come down from the trees. About once every week, they go down to go to the bathroom, slowly moving about by digging their front claws into the dirt and dragging their bodies. If they are caught by a hunter, sloths will become aggressive, biting fiercely, striking with their claws, and screaming.
