Over 100 great white shark attacks happen each year. As a result, often     1     (refer) to as “man-eaters”, great whites are thought to hunt and kill humans. However, this is actually wrong, since great whites have rarely killed their human victims. If Steven Spielberg     2     (make) his film Jaw s in a different way, people would have had a positive impression on great whites. In fact, a person has a greater chance of being killed by lightning     3     by a great white.

One of the most common     4     (cause) for great white attacks is that great whites don’t see well. It is thought that they often mistake a person for a seal or a sea lion,     5     many people find hard to believe. But there is reason to doubt this. Some research now shows that great whites can actually see very well. When     6     (attack) seals, great whites move up to the surface and bite with great force. However, when they approach humans, they often move in slowly and bite     7     (little) hard. They take a bite, feel them over, then move on.

Great whites “attack” because they are actually curious animals that want     8     (investigate) things. Experts believe that it’s possible that great whites use their bite not just to kill and eat,     9     also to gather information. According to this idea, once a great white identifies what it is biting, it simply lets go. They are     10     (simple) trying to learn what they are.

Jessica and I wanted a dog more than anything else on Earth. At night, after Mom and Dad had gone to bed, Jessica and I would sneak out our bedroom windows and we’d sit together on the roof and talk about dogs. Sometimes, we had an argument about what our ideal dog would be. But it didn’t really matter — any dog or puppy (小狗崽) would do.

One summer night, as we sat together on the roof, Jessica saw something. “What’s that?” She pointed down toward a dark shadow on our driveway. The moon was up, and everything looked either black or milky. All I saw was darkness. Then the shadow moved. For one astonished second, Jessica and I just stared at each other. Then we scrambled down onto the porch. There in our yard stood a dog. A big, black dog with long hair. Jessica made a little kissing noise and held out her hand. And the dog came to us slowly, taking a few steps forward, then a step back, not sure whether to trust us, I guess.

“She’s a female,” said Jessica.

“Oh,” I said, pulling back and looking. The dog was so skinny and her coat was full of dirt. She must be a homeless dog.

“What can we give her?” I asked. Then I had a thought. “Bread! I’ll get her a big loaf of bread.” So, Jessica waited with the dog, and I sneaked into the kitchen to fetch the bread.

The dog got the bread and ran into the shadows and disappeared. We smiled at each other in the moonlight, our insides full of excitement. “We’re going to have a dog!” I whispered.

On the following nights, the dog, who we named “Shadow”, would come and Jessica and I would prepare food for her. But we never saw her eating anything, and each time she got the food she would run away into the darkness quickly.

“Why didn’t she eat?” I was curious. “And she is still so skinny.”

“We can look into the case,” Jessica said. So, we decided to find out the truth.

One night, we followed Shadow secretly at a distance.

3 . What event did the man participate in?

A．Waste recycling.

B．Beach cleaning.

C．Tree planting.

4 . For uncounted generations, trillions of coral polyps (珊瑚虫) have lived and died, leaving behind a material called limestone. Throughout History, limestone was used to construct the Great Pyramid of Egypt, as well as many churches and castles.       1    . We can call them reefs (礁体). They can be even larger in scale than the most impressive buildings and structures made by humans.

    2    

Indeed, a living coral reef is remarkable, a “city beneath the sea” filled with a rich variety of life. Most coral reefs can be found in warm, shallow oceans. They occupy just a small part of the ocean floor, but host 25 percent of all ocean life. Each reef is full of colorful fish as well as coral that forms wonderful patterns. In addition to their beauty, the reefs are an important food source for fish, and for. humans.

Threats to coral reefs

    3    . For example, reefs can be damaged when the coral is taken for use in building materials or jewelry-making. Illegal fishing methods also harm reefs. These methods can help fishermen get a good catch, but their negative effects on the reefs are significant. Blast fishing involves setting off bombs in the water to kill as many fish as possible.     4     In addition, global warming has caused many reefs to become sick. A 2018 UN Report predicted that up to 99 percent of the world’s coral reefs may decline if global warming continues.   

Reasons for hope

These threats to coral reefs are very serious, but there is reason to hope that they will survive. If we take steps toward coral reef conservation, it is likely that these tiny creatures — which survived natural threats for millions of years — will be able to rebuild. As conservationist Robert Richmond says, “    5    . ”

A．A diversity of life

B．A city above the sea

C．Given a chance, they can come back

D．Yet the greatest limestone structures in the world are built underwater

E．Various human activities can cause great harm to the world’s coral reefs

F．As a result, the fish became stunned, which makes them easy to collet.

G．This kills most living things nearby and causes damage to the reef’s structure

6 . Scientists have long considered the question of whether and how plants communicate. For years, the topic sparked controversy. Books like 1973’s The Secret Life of Plants suggest that plants grow well if you sing or play classical music. Such statements were later debunked: Any evidence that music helps plants grow is not convincing at all. Still, researchers firmly believe there is some sort of communication going on between plants.

Plant communication is a complicated topic. What we do know is that plants have a wide range of mechanisms for communicating with each other and their surroundings. “It’s quite clear that plants are not just unresponsive victims, but that they are very aware of nearby things,” says Richard Karban, an entomologist at the University of California. “And they respond to reliable information.”

When a plant sends out chemicals in the air in response to a perceived threat, other sensitive leavcs on that same plant, as well as the leaves of their neighbors, perceive those signals and subsequently increase their own defenses. Karban’s research, for instance, shows that plants sound the alarm when they’re attacked by pests, so that other plants respond by growing faster and stronger. Even other species, like tobacco, can sense and react to the alarm.

In a study published in the journal Cell this March, Lilach Hadany, a professor at Tel Aviv University, put tomato and tobacco plants in an isolated box and then recorded ultrasonic (超声的) sounds. They experimented with, cutting stems or leaving them without water to simulate drought. The researchers found that the plants emitted (popping and clicking sounds at around 60 decibels in response, approximately as loud as human chatter. These sounds were at an ultrasonic frequency that humans can’t naturally hear, however. Hadany’s team even matched different sounds to the plants’ environment. And each type of stress could be matched with a specific, identifiable sound.

“We don’t know if they’re using the sound, or if the sounds are emitted in a completely passive way due to physiological changes,” Hadany says. “But we do know they are in the air, and they contain information.”

1. What does the underlined word “debunked” in Paragraph 1 mean?

A．Confirmed.

B．Ignored.

C．Disproved.

D．Promoted.

2. What does Karban’s research indicate about plant communication?

A．Plants can make no response to their attackers.

B．Chemicals are sent by plants to attack the perceived threat.

C．Plants rely little on their neighbors’ information to survive.

D．The alarm sounded by one plant travels beyond plants and species.

3. What can we learn about the sounds emitted by plants from Hadany’s study?

A．The sounds are loud enough to scare away pests.

B．The sounds are produced when plants are in danger.

C．The sounds can be heard by man without equipment.

D．The sounds can be matched to the human environment.

4. What is the purpose of the text?

A．To inform readers.	B．To compare things.
C．To warn readers.	D．To advertise things.

7 . Natasha Tucker’s passion for fighting plastic pollution began with a shocking moment.

While working at the Vancouver Aquarium, Tucker met a rescued dolphin whose fins were partially cut off due to fishing equipment entanglement (缠绕). This heartbreaking experience made Tucker immediately search for a way to take action against the plastic pollution that caused these injuries.

“I saw immediately that this was because of us,” she says. “I knew I had to do something. Then, I found Mind Your Plastic.”

That aquarium encounter was not the only experience that inspired Tucker to action. Other experiences like working in retail management came with witnessing tons of plastic waste. “I saw how much got thrown out, and it didn’t sit well with me,” she says.

Plastic waste in business is among what Mind Your Plastic is seeking to end via its three key programs: the Circular Economy Ambassador Program(CEAP) for educators and youth, the Plastic-Free Events Policy Program for municipalities (市政当局) and the Plastic Awareness and Reduction Tool-kit s (PART) Program for businesses.

When people donate to Mind Your Plastic, their dollars directly support these programs and help them effect change. Through direct partnerships with local educators, municipalities and businesses, these programs connect Canadians with direct ways to take action. The CEAP program, for example, helps teachers educate youth about the circular economy, lead local cleanups, and track collected waste.

The blame game is another area in need of transition, according to Tucker, who says that big companies, not customers, should carry the responsibility to solve Canada’s plastic pollution problem.

“It’s felt for a long time like the responsibility is placed on the customers,” says Tucker. “That needs to stop.”

Tucker says this perspective (观点) can be shifted by individuals creating public pressures—for example, pushing for policy—and using their dollars to support more sustainable, circular alternatives until these policy changes happen.

“This makes policy a valuable tool. And big business may say there’s no interest, but we know there is,” she says. “Let’s use our dollars to prove that, and challenge policymakers to help make change happen.”

1. What first inspired Natasha Tucker’s passion for fighting plastic pollution?

A．Tucker felt uneasy about the large quantity of the plastic.

B．Tucker was unconcerned about the amount of plastic waste she saw.

C．Tucker enjoyed managing so much plastic waste.

D．Tucker thought the amount of plastic waste was acceptable.

3. According to the text, how does Mind Your Plastic aim to effect change?

A．By blaming consumers for plastic waste.	B．By providing education and partnership.
C．By quarreling with big businesses.	D．By stop ping using plastic products.

4. What is the passage mainly about?

A．The harmful effects of plastic pollution on life in the ocean.

B．Natasha Tucker’s personal experiences and her fight against plastic pollution.

C．The programs of Mind Your Plastic to reduce plastic waste.

D．The responsibility of big companies in solving Canada’s plastic pollution problem.
