1 . CLIMATE CHANGE REQUIRES THE WORLD’S ATTENTION
We have known about climate change for decades. There is little doubt that Earth is getting warmer and warmer (see the graph). A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate.
In 2013, a lot of people were shocked by a news photo of a dead polar bear that was found on Norway’s Arctic island of Svalbard. According to the scientists who found its dead body, all that remained of the polar bear was “skin and bones”. An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have starved and died. Experts claimed that low sea-ice levels caused by climate change meant the bear could not hunt seals as before, so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on Earth’s ecology.
Then what is causing the increase in the global average surface temperature? Climate scientists often mention a key climate process called the “greenhouse effect”, which has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect. The “natural” greenhouse effect refers to the fact that heat from the sun enters the atmosphere and warms Earth’s surface as short-wave radiation. The heat is released back into space at longer wave lengths. Greenhouse gases in the atmosphere, such as methane and carbon dioxide, trap some of the heat, keeping Earth’s climate warm and habitable. Without this process, Earth could not sustain life. However, the “man-made” greenhouse effect has now become a big problem. When people produce huge amounts of extra greenhouse gases by burning fossil fuels, more heat energy is trapped in the atmosphere and causes Earth’s surface temperature to rise quickly.
There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only causing serious damage, but also costing human lives. Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a higher price to pay. In fact, news reports are frequently broadcast about extreme rainstorms and heatwaves causing deaths and economic losses.
Continued greenhouse gas emissions will result in further warming and long-lasting changes to the global climate. This requires the attention of people all over the world. Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce. It is our responsibility to seize every opportunity to educate everyone about global warming, along with its causes and impacts, because this is the most serious issue affecting all of us on this planet. So what will you do to help?

2 . A tree-planting initiative in Kenya has seen over 30,000 trees being planted. The Green Generation Initiative is a Kenyan charity that has been planting trees to counter climate change and the reduction in forest in the East African nation since 2016.
......
Speaking to world leaders at the recent United Nations Climate Conference in Glasgow (COP26), Elizabeth issued a serious warning on the threat of climate change. Over two million of Kenyans are facing climate related starvation. In 2025, half of the world’s population will be facing water shortage. The climate crisis will displace 80 million people in sub-Saharan Africa alone.
Elizabeth said, “I have been doing what I can. Inspired by the great Wangari Maathai, I founded a tree growing initiative that enhances food security for young Kenyans.” So far, they have grown 30,000 fruit trees to maturity, providing desperately needed nutrition for thousands of children. “Every day we see that when we look after the trees, they look after us. We are the adults on this Earth right now, and it is our responsibility to ensure that the children have food and water,” she added.
Which of the following can best describe Elizabeth Wathuti?| A．Friendly and talented. | B．Caring and responsible. |
| C．Honest and determined. | D．Ambitious and humorous. |
3 . Tree-planting, intended to help draw down carbon dioxide from the atmosphere, has become a synonym (同义词) for climate action. In our constant focus on trees, we’ve developed a fixed understanding: Trees absorb carbon dioxide, end of story. The reality is that trees don’t grow well alone. They exist within complex communities, helped along by each other as well as the animals they coexist with. The woodland isn’t nature’s only carbon sink: Grasslands and oceans also help reduce the carbon level and rely on a healthy amount of biodiversity.
That’s what the paper, published in Nature, wants to get across. Co-author Oswald J. Schmitz, a professor of ecology at Yale University, said trees might not be able to do their carbon-uptake job efficiently without the right animals in their ecosystem. That’s because animals animate the carbon cycle through their behavior and roles in the ecosystem. He added that the very presence of wild animals could cause feedback effects that change the ecosystem’s capacity to absorb, release, or transport carbon.
In Serengeti, for instance, the sharp decline in wildebeest (角马) population s during the mid-20th century allowed grass to grow wildly, eventually promoting wildfires that consumed 80 percent of the ecosystem annually and led to a net release of carbon dioxide into the atmosphere. When disease management and bans on illegal hunting helped animal populations recover, a greater share of the carbon stored in plants was consumed by wildebeest and released as waste, keeping it in the system and restoring the grassland as a carbon sink.

4 . A 12-year-old girl, Eleanor Woods, has created a green backpack that filters (过滤) out air pollution. Her innovative bag won the award of the “Backpack to the Future” competition.
The competition was launched to encourage students to combine an interest in fashion with a career in science, technology, engineering or maths.
Powered by green energy from solar power and a dynamo-a machine that converts mechanical energy into electrical energy-the backpack filters polluted air before fanning out cleaner air nearby.
Air pollution was always Eleanor’s concern. Meanwhile, spending a lot of time with her asthmatic (患哮喘病的) mum, Eleanor especially focused on how pollution affects a person’s health and the spread of diseases. “We have an air filter at home because my mum has mild asthma. But what if she wants to go out? It would be inconvenient and dangerous! My Breathe Better Backpack is about keeping those like my mother safe using an air filter. It looks cool and will help get them outside and fight off colds,” Eleanor said.
The girl added, “My generation has really realized pollution, and we have lessons on it at school. This is another reason why I designed this, because we need to do something.”
1. Who will most probably benefit from the backpack?| A．Students living in poverty. | B．Those suffering from asthma. |
| C．People working in an open way. | D．Judges worried about pollution. |
| A．Humorous and modest. | B．Ambitious and selfless. |
| C．Confident and fearless. | D．Creative and considerate. |
5 . On the outside, 12-year-old Luna seems like your average kid. It’s not until you get to know her that you learn that Luna is anything but average.
Bom with a heart defect (缺陷) called dextrocardia, Luna has had three open-heart operations and continues to pursue her interests in art and fashion. But when Luna was approached by athletic shoe company Saucony to design a shoe for sale across the country, it came as quite a surprise.
......
“Rather than just a donation, we wanted to create an experience and a moment that would not only raise money, but also awareness to highlight all the amazing work that’s being done at BCH,” says Chris, Saucony’s vice president. “Specifically, we wanted to give some of the BCH kids an opportunity to share their story and their talents with the world.”
1. What can we learn from Chris’ words?| A．It’s unwise to raise money. |
| B．It’s optional to seek donations. |
| C．It’s wonderful to study art. |
| D．It’s necessary to show kids’ talents. |
| A．Gifted and determined. | B．Generous and serious. |
| C．Grateful and helpful. | D．Creative and sensitive. |
6 . He was amazed at the results. The plants and animals in the eco-machine took the sludge as food and began to eat it! Within weeks, it had all been digested, and all that was left was pure water.
Over the years, John has taken on many big jobs. He developed a greenhouse — like facility that treated sewage (污水) from 1,600 homes in South Burlington. He also designed an eco-machine to clean canal water in Fuzhou, a city in southeast China.
“Ecological design” is the name John gives to what he does. “Life on Earth is kind of a box of spare parts for the inventor,” he says. “You put organisms in new relationships and observe what’s happening. Then you let these new systems develop their own ways to self-repair.”
1. What is the author’s purpose in mentioning Fuzhou?| A．To review John’s research plans. |
| B．To show an application of John’s idea. |
| C．To compare John’s different jobs. |
| D．To erase doubts about John’s invention. |
| A．Nature can repair itself. |
| B．Organisms need water to survive. |
| C．Life on Earth is diverse. |
| D．Most tiny creatures live in groups. |
7 . The ebike has become an essential item, and even the King has been spotted riding one. According to the market research company Mintel, sales have almost tripled over the past five years. While ebikes have become increasingly commonplace, they are still undeniably expensive. You can pick up a perfectly adequate push bike for £300, but most ebikes cost nearly £2, 000. Now, Cycling Electric, designed to help consumers choose an ebike, offers the following recommendations.
Best folding bike
Carbo Model X
Price: £2, 799 | Weight: 13. 3kg
Range: up to 34 miles
This is one of the most convenient bikes, from a little-known label. The lightweight Carbo X is the perfect example of convenience thanks to its carbon frame and belt drive, instead of a metal bike chain. This makes it lighter and less likely to get messy than an electric Brompton, with its more traditional, oily chain.
Most stylish
Temple Cycles Classic
Price: from £2, 995 | Weight: 19kg
Range: up to 74 miles
This Bristol-based brand is known for its elegant pushbikes, which are hand-built in the city. This is its electric version. It’s a very sleek and functional commuter option and not too heavy. Temples have fewer proprietary (品牌专卖的) parts and so are serviceable in any bike shop. Stylish as they may be, the VanMoofs and the Cowboys can be a bit more complex to get back-up and service.
The money-no-object option
Riese & Müller Nevo4 GT Vario GX
Price: £5, 380 | Weight: 28. 4kg
Range: up to 93 miles
This is a prime example of the attention to detail delivering a high-quality experience in functionality, comfort and practicality — if you can afford it. It has the capacity to handle 25kg of luggage in a pannier, powerful road lights and a beautifully smooth motor.
1. Which ebike will a consumer probably choose, who cares most about an excellent experience?| A．Carbo Model X. |
| B．The VanMoofs and the Cowboys. |
| C．Temple Cycles Classic. |
| D．Riese & Müller Nevo4 GT Vario GX. |
| A．An online post. | B．A magazine column. |
| C．A market research report. | D．An official document. |
8 . She applied strategies that web insiders are familiar with (keeping multiple browsers open, refreshing sites every 20 seconds, erasing cookies) and added a few of her special skills. “I drink a lot of coffee, and I’m a fast typer,” she says. Soon enough, Zwinggi had secured appointments for both of her parents. “I felt like a rock star,” she says.
Zwinggi decided that helping others would be her way of giving back. “I feel like I need to will us out of this pandemic,” she says. On February 10, she logged on to Facebook to let people know that she was assisting with bookings. By March 2, she’d secured appointments for 400 people, a feat (壮举) that made Nick conclude, “Marla is an angel.”
Which of the following best describes Zwinggi?| A．Caring and confident | B．Passionate and persevering |
| C．Thoughtful and talented | D．Supportive and skillful |
9 . “If you look at where hydrogen is going to be produced in Europe in the next million years, it’s in two countries, Spain and Portugal,” said Thierry Lepercq, the founder and president of HyDeal Ambition, an industry platform bringing together 30 companies. “Hydrogen is the new oil.”
Lepercq is working with companies like Spanish gas pipeline corporation Enagas and global steel giant ArcelorMittal to design an end-to-end model for hydrogen production, distribution and supply at a competitive price. Criticism has centered on green hydrogen’s higher cost compared with highly-polluting “gray hydrogen” drawn from natural gas. Lepercq argues that solar energy produced in Spain is priced low enough to compete.
Globally, Lepercq said, “Electricity is 20% of energy consumption. What about the 80% that is not electrified? ... You need to replace those fossil fuels. Not in 50 years’ time. You need to replace them now.”
What can be inferred about green hydrogen in Spain according to Lepercq?| A．It is highly priced. | B．It is easy to store. |
| C．It is competitive. | D．It is highly-polluting. |
10 . The AIDA model is the foundation of modern marketing and advertising practice. It outlines the four basic steps used to persuade potentials to make a purchase. The first three steps lie in creating attention (A), decorating interest (I), and building desire (D) for the product, before the fourth step — the “call to action” (A) — tells them exactly how and where to buy. AIDA can channel the customer’s feelings through each stage toward reaching a sale.
......
“Call-to-action” is where all of the initial hard work pays off and leads to the action from a potential customer. For example, they might pick up the phone to discuss the idea of a trial of the services or, alternatively, they may just buy that product or service that has been promoted to them all along.
And AIDA is used to great effect in the movie industry. Movie studios begin their marketing campaigns months in advance. The campaigns develop by offering attractive flashes of the movie without giving too much away. Desire is inspired by the release of the full preview which is fully designed to show the exciting moments of the movie, from special effects to humorous lines of dialogue on the opening weekend. Advertisements in newspapers and on television focus on the movie’s release, inviting the consumer to go and buy a ticket.
1. What is the purpose of practising AIDA?| A．To create jobs. | B．To increase sales. |
| C．To research markets. | D．To introduce products. |
| A．To design an AIDA model. | B．To display how AIDA works. |
| C．To show how to make a movie. | D．To advertise the movie industry. |
