21、A team of Australian and Japanese scientists are using the bacteria-killing (杀菌的) characteristics of the wings of insects, such as cicadas (蝉) and dragonflies, to create lab-made material that can kill up to 70 percent of bacteria. Insect wings have sharp points which destroy bacteria on contact. The new technology has a major influence on food storage because so much is wasted when bacterial growth goes into food. The new bacteria-killing food packaging will improve shelf life and reduce waste.
Professor Elena Ivanova from RMIT University’s School of Science said the team had successfully applied a natural fact to plastic. “We knew the wings of cicadas and dragonflies were highly-effective bacteria killers and could help inspire a solution, but replicating nature is always a challenge,”Professor Ivanova said. The breakthrough was a big step towards a non-chemical, antibacterial packaging solution for food manufacturing, she added.
Professor Ivanova and her colleagues first discovered that insect wings were natural-born bacteria killers a decade ago. The team is now working on improving the technology to find the best way to mass produce the bacteria-killing packaging. But the possible applications of the technology do not stop with packaging. In an earlier 2020 review published in Nature Reviews Microbiology, the researchers detailed how possible uses might one day even include defeating drug-resistant bacteria.
Professor Ivanova said that at the time finding non-chemical ways of killing bacteria was very important, with more than 700,000 people dying each year due to drug-resistant bacterial infection. Bacterial resistance to some medicine is one of the greatest threats to global health and regular treatment of infection is becoming increasingly difficult,” Professor Ivanova said. “When we look to nature for ideas, we find insects have developed highly-effective bacteria-killing systems. If we can understand exactly how insect-inspired patterns kill bacteria, we can engineer exactly these shapes to improve their effectiveness against infections.”
【1】Why do wings of insects have the ability to kill bacteria?
A．They smell bad.
B．They are usually wet.
C．They move very fast.
D．They have sharp points.
【2】What can best replace the underlined word “replicating” in paragraph 2?

【3】What is Professor Ivanova probably eager to find out?
A．What kind of shape the cells of insects have.
B．What’s our body’s defence system against infection.
C．What’s behind the bacteria-killing systems of insects.
D．Why so many people die of bacterial infection.
【4】What can be the best title for the text?

22、 The world's oceans make life possible on this planet.They help regulate the global climate, absorb carbon dioxide and provide food and livelihood for billions of people.
But even though they cover more than 70% of the Earth's surface, our oceans are being ruined by lots of plastics, overfishing and increasing temperatures brought about by climate change and if there is one message this year's World,'s Oceans Summit tries to send it's that something must be done now to protect them.
The news that we have had from our scientists is that we are marching into a very hazardous situation.It's pretty obvious what is required is not just short-term change sometimes soon -these advocates are calling for complete change now.
But we have still got time over the next 10 years to lower our greenhouse gas emission(排放) to a level at which we will not reach that 2 degree warming stage.As you would know, once we get to 2 degrees, we lose all coral reefs in the world,for example.We're now training towards 3 degrees.
The biggest declaration to come out of the summit is the Blue Prosperity Coalition, which has the ambitious goal to ban 30% of the world,s ocean fishing by 2030.We've over-fished the oceans, and we have five to ten years to really reverse the trends as before or it's going to be too late.
We rely on the oceans for so many things, livelihoods, the food we eat and the air we breathe The oceans absorb a ton of carbon and if we don't fix the oceans now, it's going to be too late.
The coalition needs a lot more support from world governments and coalition members say with smart management they can achieve their goals while keeping fishing production without causing much economic hardship.
【1】Which of the following best explains"hazardous"underlined in Paragraph 3?
A. dangerous. B. Brilliant.
C. Hopeless. D. Promising.
【2】What does the text suggest people do?
A. Make a plan later. B. Stop using plastics.
C. Ban fishing completely. D. Reduce the greenhouse gas emission.
【3】What can we learn from the text?
A. It's too late to protect the oceans now.
B. We will not reach 3 degree warming stage.
C. Great economic hardship will be unavoidable.
D. A joint effort is needed by the world governments.
【4】What's the author's purpose in writing the text?
A. To emphasize the importance of the oceans.
B. To call for complete change to protect the oceans.
C. To show the alarming pollution of the oceans.
D. To talk about the bad effects of climate change.
23、Almost everyone has heard the expression “the calm before the storm.” It is usually used to describe a peaceful period just before a very stressful situation or a tense argument.
British sailors coined the phrase in the late 1600s; they noted that before certain storms the seas would seem to become still and the winds would drop.
Science has given us the reason. According to US website HowStuffWorks, a calm period occurs because many storms, tornadoes and hurricanes draw in all the warm and humid(湿热的) air from the surrounding area. As this air rises into the storm clouds, it cools and acts as “fuel for the storm, like petrol in a car”. Once the storm has taken all the energy it can from the air, it is pushed out from the top of the storm clouds and falls back down to ground level. As the air goes down, it becomes warm and dry. Warm and dry air is stable, so once it covers an area, it causes a calm period before the storm. This same process also causes the “eye of the storm” in hurricanes and tornadoes. In these conditions, the calm occurs in the center of the storm because of the strong rotating (旋转的) winds.
The Weather Network has a tip for working out how far away a storm is. First count how many seconds there are between a flash of lightning and a clap of thunder, roughly three seconds equal one kilometer. So, for example, if you count nine seconds, the storm is about three kilometers away. A good method is that if your count is below 30 seconds, you should seek shelter straight away.
However, due to the complexity of storm system, not all storms take place after calm. Given the right conditions, some storms announce themselves with heavy rain and fierce winds.
So, your best bet is to keep yourself updated with weather reports for any predictions regarding a coming storm in your area. That's the most reliable way to predict the next display(展示) of nature's temper (脾气).
【1】What is the function of Paragraph 3?
A．To describe how the eye of the storm comes into being.
B．To stress why tornadoes and hurricanes are destructive.
C．To explain why a peaceful period occurs before some storms.
D．To remind how dangerous a storm can be in certain situations.
【2】If you count fifteen seconds between a lightening flash and a thunder clap, the storm may be .
A．one kilometer away
B．three kilometers away
C．four kilometers away
D．five kilometers away
【3】What can we learn from the text?
A．Heavy storms don't usually last long.
B．It is not always quiet before a storm.
C．Storms have a big influence on our life.
D．Weather reports often fail to predict a storm.
【4】Where is this text most likely from?
A．A travel journal.
B．A science fiction.
C．A literature review.
D．A geography magazine.
24、Ian McKenna was in third grade when he learned that many kids at his Austin school weren’t getting enough to eat at home. He wanted to help, but local volunteer organizations turned him away, saying he was too young. So he decided to find his own solution. For years, he had been gardening with his mother, and they often sent their vegetables to the neighbors. “I’m good at gardening,” says McKenna, now 16. “Why not plant a garden at school, so that kids in need could take food home?”
McKenna persuaded his school to set aside space for a garden; then he asked the community for donations of seeds and equipment. Other students donated their time. Within months, McKenna’s garden was producing lettuces, tomatoes and cucumbers for students and their families. Now,seven years later, McKenna’s Giving Garden project has expanded to five area schools in addition to his own backyard garden. For most of his gardening activities, McKenna wears the same T-shirt in different colors, with his personal motto on it: BE A GOOD HUMAN. To him, that means helping in any way you can, no matter what your age.
“Even a smile might change someone’s life,” he says. “It lets them know that they are important. It can make their day.”
When COVID-19 hit the U. S., McKenna redoubled his efforts, cooking up to 100 meals to distribute (配送) to the hungry on the weekends. When social distancing meant that volunteers couldn’t work on community garden, he started offering online classes and a gardening hotline so families could grow at home. While gardening is his core focus, McKenna says he is always looking for new ways to help the hungry.
【1】What caused Ian’s decision to help the kids in his own way?
A．Being rejected by volunteer groups.
B．Being good at gardening.
