1 . Enjoying a swim at their local beach was once a daily pleasure for Melati and her sister, Isabel. But in 2013 when Melati was 12 and Isabel just ten, the sisters started to lose ________ for swimming in the waters near their home on the island of Bali. More often than not, plastic bags would circle around them as they ________. Then as they walked back to shore, red and white plastic shopping bags would ________ their legs and body.

Melati didn’t think much about it until later in 2013 when her teacher gave a lesson on world ________ like South Africa’s Nelson Mandela and England’s Princess Diana, whose efforts had inspired movements of ________ change. That day Melati walked home in ________, thinking something needed to be done to preserve the beautiful island from becoming ________ by waste.

Melati and Isabel started by sharing the idea with others. Soon they’d ________ a team of 15, made up of schoolfriends. They ________ their group ByeBye Plastic Bags(BBPB). Its mission was ________ stop people in Bali using plastic bags.

The following year the BBPB team spent their lunchtimes ________ meetings and organizing an online petition (请愿) to collect signatures to ban plastic bags. Within 24 hours of ________ more than 6000 people both local Balinese and people from around the world had ________. “This was the first moment when we knew, we were onto something,”Melati says.

Years later, the girls’ enthusiasm has resulted in big changes. In 2017, they organized Bali’s first beach clean up. Around 12,000 people collected 36 tonnes of rubbish. In 2018 BBPB ________ the government to ban single-use plastic bags and straws. The ban took effect in July 2019.

Today BBPB is a global youth movement and has over 50 teams in 29 countries. “We didn’t start with any clear ________,”Melati admits. “We didn’t know how we were going to complete a seemingly easy task but we knew that we wanted to and had the desire to figure it out.”

2 . While it may seem like fish will drive cars when pigs fly, in a new experiment scientists put goldfish’s sense of direction to the test.

A scientific team at Ben-Gurion University in Israel taught several goldfish to drive a robotic “car” — a tank of water on wheels-around a room. Researchers’ originally thought teaching goldfish to navigate(航行)such unfamiliar areas may seem like a fish-out-of-water idea, but they took to it like naturals.

The motorized fish tank was equipped with a camera to track the fish’s position. When the goldfish swam towards one of the walls, the fishmobile drove in that direction.

The researchers trained the fish over a dozen 30-minute sessions to drive to the center of a small room towards a pink board by giving the fish a treat whenever it arrived at its destination. In the first session, the goldfish averaged between 2-3 successful trips. By the end of the experiment, the fish were averaging between 17-18 successful trips per session. As with humans, some of the fish behaved smarter and quicker than others-taking faster and more direct paths to their target.

Throughout the experiment, researchers changed up the starting position of the fishmobiles. Even in different locations, the goldfish were still able to reach the pink board. This finding ruled out the possibility that the fish were just memorizing the pattern of movements to get to their reward. These marine animals were actually planning new routes to get to their destination.

“That was pretty conclusive that the fish actually navigate,” said Ohad Ben-Shahar, coauthor of the study. The animals’ sense of direction and orientation isn’t limited to the water.

Maybe next they’ll teach a fish how to ride a bicycle.

3 . In February 2021, the government of Vietnam released a draft of the country’s latest national power development plan (PDP 8) for 2021 to 2030. The draft PDP 8 expands wind and solar capacity and improves grid (输电网) infrastructure to ensure that the stable operation with a higher share of renewable energy.

Vietnam increasingly relies on coal imports because coal-fired power plants have been used to meet the rapidly increasing electricity demand. More than half of Vietnam’s electricity generation came from coal in 2020. The country also relies heavily on hydroeletric generation (水利发电) and is home to a number of large rivers. However, hydro’s reliability is affected by droughts and water shortages. Non-hydro renewable sources, such as wind and solar, made up 5% of Vietnam’s electricity generation in 2020.

Expanding non-hydro renewable capacity will likely help Vietnam rely less on coal,reduce carbon emissions (排放), and increases electricity generating capacity. With its strong emphasis on renewables, the draft PDP 8 is quite different from previous plans, which rely heavily on coal,hydropower and natural gas sources.

However, Vietnam’s underdeveloped grid hampers (阻碍) these capacity additions. Some of the country’s transmission lines are operating at a full load or are overloaded, especially in the region where solar capacity in concentrated. Electricity producers have reduced generation from renewables because of grid limitations. The country needs new transmission and distribution infrastructure to accommodate capacity additions and transmit electricity to where it is needed.

One major grid development underway is a 461-mile transmission line extension with three 500-kilovolt transmission lines. These transmission lines will connect nine cities and provinces across central and southern Vietnam.

1. Which did Vietnam rely on most for power generation in 2020?

A．Wind.

B．Water.

C．Coal.

D．Sunlight.

2. What’s special about the draft PDP 8 compared to previous plans?

A．It is more environmentally friendly.

B．It depends more on hydroelectric power.

C．It is less expensive and far more efficient.

D．It meets the country’s growing electricity needs.

3. How will Vietnam keep pace with its capacity growth?

A．By reducing solar capacity.	B．By repairing transmission lines.
C．By rewarding electricity producers.	D．By strengthening power infrastructure.

4. What is the best title for the text?

A．Vietnam’s energy structure in the future.

B．Vietnam’s latest power plan to expand renewables.

C．Difficulties in expanding clean energy in Vietnam.

D．Measures to develop renewable energy in Vietnam.

4 . With millions of people visiting China’s mountains every year, keeping them trash-free is quite difficult. That’s where Spiderman cleaners come in.

Spiderman cleaners get their name from the dangerous nature of their job. They dangle (悬荡) thousands of feet above the ground on the side of steep mountain cliffs (悬崖), supported only by ropes, as they try to collect hard-to-reach trash. To show the danger of their work and make tourists think twice before littering, some of them actually exchanged their regular uniforms for Spiderman costumes. This has made them a hit with visitors, who often stop to watch these real-life versions of their favourite superhero, rewarding them with applause and cheers when they complete their task.

Spiderman cleaners really risk their life every time they go after a piece of trash left in popular scenic spots by tourists who never stop to think about the impact their deed may have on nature or the people tasked with cleaning up after them. To them, injuries are frequent and the stress is so great that they sometimes faint (晕倒) on the job. Because of the dangerous nature of the job, few people have the courage to work as Spiderman cleaners and those who do are rewarded generously. For example, the Guimeng Scenic Spot put up an ad for a Spiderman cleaner, offering 10,000 yuan a day, but also mentioned that the work was to be performed “at your own risk”.

Spiderman cleaners all around China pick up tons of litter from the scenic mountains every year. Some of them have been doing it for over a decade and they don’t plan on stopping anytime soon. Luckily, after the job has been reported by the national media during the past few years, more people have begun to think twice before littering. Less and less trash has been found in recent years, which means Spiderman cleaners don't have to risk their life as often as they used to.

So the next time you feel like throwing a piece of trash in a scenic spot, spare a thought for these unsung heroes and how they risk their life to keep the world clean for everybody.

5 . When thinking about ancient and mysterious animals, dinosaurs may first come to mind. But a new study shows octopuses (章鱼) appeared on Earth before the era of dinosaurs.

Scientists have found an ancestor of octopuses — a 330-million-year-old fossil (化石) unearthed in Montana, United States. The research concluded the ancient creature lived millions of years earlier than previously believed.

Apart from the impressive age, the octopus is also one of the oddest creatures in existence. Their mouths are in their armpits (腋窝); they have three hearts; they have blue blood. And the grace? I mean, who has grace like this?” Sy Montgomery, a German-born naturalist, told CBS News.

Of all the octopus’ oddities, perhaps the most extraordinary one is that the octopus has one large central brain, and eight mini-brains, one in each arm. As a result, the arms can solve the problem of how to open a shellfish while their owners are busy doing something else, like checking out a cave for more edible goodies (可食用的东西), according to Smithsonian magazine.

The ancient creature is also well-known for its disguises. The octopus can change its shape, colors, patterns, even the texture (纹理) of its skin. It can transform itself to look like seaweed in just the blink of an eye. This ability is called dynamic camouflage (动态伪装).

“I would argue that dynamic camouflage is a form of intelligence,” Roger Hanlon, a top octopus researcher said in a TED Talk.

The camouflage may look like a reflex (本能反应), but it’s not. It doesn’t just happen instinctively. They actually think and decide how to best camouflage themselves. “This is a decision-making process,” Hanlon said. “They’re not only taking into account the surroundings for camouflage, but also an approaching threat. And they’re calculating all the time about what they’re going to do next.”

1. What does the fossil unearthed imply?

A．Octopuses and dinosaurs have a common ancestor.

B．The oldest octopuses existed 330 million years ago.

C．Octopuses appeared on Earth at the same time as the dinosaurs.

D．Octopuses lived on Earth much earlier than we previously thought.

2. What do octopuses’ brains enable them to do?

A．Make decisions more quickly.

B．Adapt to different surroundings.

C．Find food faster than other species.

D．Perform many tasks at the same time.

3. What does Roger Hanlon think of the octopus’ ability to disguise itself?

A．It is an instinctive reaction.

B．It is connected to its multiple brains.

C．It involves a process of making a thoughtful decision.

D．It takes too long for the octopus to respond to dangers.

4. Which of the following is a suitable title for the text?

A．The Origin of Animals

B．The Mysteries of Animals

C．The Disguises of Octopuses

D．The Exploration of Octopuses

7 . From climbing a human ladder to swimming with the crocodiles(鳄鱼), there's nothing this Spanish botanist wouldn't do in the name of plants.

Carlos Magdalena the Spanish botanist tried to ignore the "Crocodile Danger" sign as he walked into the lagoon. Based in the hot houses and labs of London’s Kew Gardens, he thought he’d spotted a new waterlily species and it wouldn’t be the first time he’d risked his life doing his job. His mission is to save the world’s most endangered plants. As well as Harrison Ford’s film character, the great gardener is also known as the Messiah, the Code Breaker and the Plant Whisperer. He’s suffered dehydration in the planet’s largest desert, driven through rivers to reach an uncommon vegetation and experienced sickness in the Peruvian Andes, where he climbed a human ladder next to a towering drop to reach a rare flower.

“Directly or indirectly plants provide the air we breathe, medicines, clothes, shelter, food and drink,” he says in a firm voice. “Without them we wouldn't be here. It’s as simple as that.”       

Carlos grew up rolling the peaks and valleys of northern Spain in search of natural wonders but quickly learned all was not well.

There are some 400,000 plant species, with many more waiting to be discovered, and it’s estimated that a quarter of them are facing dangers of dying out. “They need our help and we should use whatever means possible to ensure their survival.”

Often peering into microscope late into night, Carlos marked himself out in the botanic world. Before long he came to understand that plants have a way of talking and to understand their needs, you had to listen to them. His work was daunting(令人怯步的) but he eventually triumphed. “It was like scoring the winning goal in a World Cup final,” he says.

10 . There are 156 known species of glass frogs living throughout the neotropics. Recent advancements in genetics are giving researchers a revealing look into the lives of these one-inch-long tree dwellers, some of which are the size of a paper clip.

Scientists have discovered, for example, that male glass frogs in some species are stellar parents — a rare trait among vertebrates (脊椎动物). Males of at least 24 species not only protect their eggs from predators but also actively care for them. While the embryos (胚胎) develop, males of some species, such as the sun glass frog sit atop their egg clutch "like a chicken," keeping the eggs hydrated until they hatch into tadpoles (蝌蚪).

New research is also discovering how the glass frog's transparent belly forms. It's suspected that young glass frogs physically rearrange the insides of their cells and tissues to become transparent adults. Fluid between the tissue cells may also contain a substance that allows light to travel through.

Another mechanism that may allow glass frogs to blend into the green leaves on which they doze during the day is called "a biological mirror", a kind of shield or covering of crystals in many of their tissues, which reflects up to 30 percent of the light that normally reaches them. Those crystals amplify the light signal, and the frog's green looks brighter.

Many scientists studying glass frogs arc motivated by the fact that some of their subjects are disappearing—and fast. Agriculture, cattle grazing, and mining projects in the Andes are taking over the frogs' already fractured forest homes.

"As soon as they are discovered, many species are declared endangered," Guayasamin, a biologist in Ecuador, says "yet there could be an advantage in conserving such isolated ponulanons." All could be inspired to work together to set aside frog-rich patches of land as reserves, ensuring that these delicate creatures have a solid chance at survival.

1. What can we know about glass frogs?

A．They are regarded dangerous.	B．They are small animals.
C．They are of different colors.	D．They live in the water.

2. What does the underlined word "stellar" in paragraph 2 probably mean?

A．Strange.	B．Ambitious.
C．Excellent.	D．Different.

3. How can glass frogs hide themselves in the green leaves?

A．They physically change their cells.	B．They contain transparent fluid.
C．Crystals in their tissues reflect light.	D．Light signal makes them greener.

4. What is Guayasamin's suggestion for endangered glass frogs?

A．Stopping cattle grazing.	B．Building frog reserves.
C．Improving frog popularity.	D．Planting more forest trees.
