【推荐2】Milwaukee, Wisconsin, is road testing a new way to keep winter roads ice-free – by spreading on them cheese brine, the salty liquid used to make soft cheese, like mozzarella.

Wisconsin, also called “America’s Dairyland,” is famous for its cheese. The state produced 2.8 billion pounds of cheese last year! a result, there was a lot of leftover cheese brine. Disposing of(处置)the brine can be expensive. So what should cheese makers do with the waste?

Normally, towns use rock salt to de-ice streets. The salt lowers waters’ freezing point, causing ice to melt(融化). But using cheese brine could help both cheese producers and cities save money, while keeping roads safe. Cheese brine has salt in it, which, like the rock salt, helps lower water’s freezing point.

In addition to saving money, cheese brine could also be a more environment-friendly option. Many people suspect that all the rock salt used every winter is harming the environment.

Rock salt is made of sodium chloride, the sane con-pound (化合物)in ordinary table salt. Sounds harmless, right? But while you probably add only a small amount of salt to your food, road crews spread about 20 million tons of salt on U.S. Roads every year!

The chemical washes off roads and goes into the ground. There it can pollute drinking water, harm plants. and eat away soil. By spreading cheese brine on streets before adding a layer of rock salt, Milwaukee may be able to cut its rock salt use by 30 percent.

Cheese brine has a downside too – a shell similar to that of bad milk. “I don’t really mind it,” Emil Norby told Modern Farmer magazine. He works for one of Wisconsin’s county highway commissions and came up with the idea of using cheese brine. “Our roads smell like Wisconsin!” he said.

Why can cheese brine help keep winter roads ice-free?

A．It is soft.

B．It contains salt.

C．It is warm.

D．It has milk in it.

A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making.

After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria (细菌)? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine.

The task John set for himself was to remove harmful substances from some sludge (污泥). First, he constructed a series of clear fiberglass tanks connected to each other. Then he went around to local ponds and streams and brought back some plants and animals. He placed them in the tanks and waited. Little by little, these different kinds of life got used to one another and formed their own ecosystem. After a few weeks, John added the sludge.

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 I,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.”

What is the basis for John’s work?

A．Nature can repair itself.

B．Organisms need water to survive.

C．Life on Earth is diverse.

D．Most tiny creatures live in groups.

【推荐1】You may not pay much attention to your daily elevator ride. Many of us use a lift several times during the day without really thinking about it. But Lee Gray, PhD, of the University of North Carolina, US, has made it his business to examine this overlooked form of public transport. He is known as the “Elevator Guy”.

“The lift becomes this interesting social space where etiquette (礼仪) is sort of odd (奇怪的),” Gray told the BBC. “They (elevators) are socially very interesting but often very awkward places.”

We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, lift users unthinkingly go through a set pattern of movements. He told the BBC what he had observed.

He explained that when you are the only one inside a lift, you can do whatever you want – it’s your own little box.If there are two of you, you go into different corners, standing diagonally (对角线地) across from each other to create distance.When a third person enters, you will unconsciously form a triangle. And when there is a fourth person it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle.

New entrants to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple – look down, or look at your phone.

Why are we so awkward in lifts?

“You don’t have enough space,” Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. “Usually when we meet other people we have about an arm’s length of distance between us. And that’s not possible in most elevators.”

In such a small, enclosed space it becomes very important to act in a way that cannot be construed (理解) as threatening or odd. “The easiest way to do this is to avoid eye contact,” she said.

【推荐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.

【推荐3】It was a cold March day in High Point, North Carolina. The girls on the Wesleyan Academy softball were waiting for their next turns at bat during practice, stamping their feet to stay warm, Eighth-grader Taylor Bisbee shivered (发抖) a little as she watched her teammate Paris White play. The two didn’t know each other well — Taylor had just moved to town a month or so before.

Suddenly, Paris fell to the ground, “Paris’s eye rolled back,” Taylor says. “She started shaking. I knew it was an emergency.”

It certainly was, Paris had suffered a sudden heart failure. Without immediate medical care, Paris would die.   At first no one moved. The girls were in shock. Then the softball coach shouted out, “Does anyone know CPR?”

CPR is a life-saving technique. To do CPR, you press on the sick person’s chest so that blood moves through the body and takes oxygen to organs. Without oxygen the brain is damaging quickly.

Amazingly, Taylor had just taken a CPR course the day before. Still, she hesitated. She didn’t think she knew it well enough. But when no one else came forward, Taylor ran to Paris and began doing CPR, “It was scary. I knew it was the difference between life and death,” says Taylor.

Taylor’s swift action helped her teammates calm down. One girl called 911. Two more ran to get the school nurse, who brought a defibrillator, an electronic devices (器械) that can shock the heart back into work. Luck stayed with them: Paris’ heartbeat returned.

“I know I was really lucky,” Paris says now. “Most people don’t survive this. My team saved my life.”

Experts say Paris is right: For a sudden heart failure, the single best chance for survival is having someone nearby step in and do CPR quickly.

Today, Paris is back on the softball team. Taylor will apply to college soon. She wants to be a nurse. “I feel more confident in my actions now,” Taylor says. “I know I can act under pressure in a scary situation.”

1. Why does Paris say she was lucky?

A．She made a worthy friend.

B．She recovered from shock.

C．She received immediate CPR.

D．She came back on the softball team.

2. Which of the following words can best describe Taylor?

A．Enthusiastic and kind.

D．Ambitious and professional.

【推荐1】Let us suppose it is now about A.D. 2060. Let's make believe it is about 47 years from now. Of course, things have changed and life is very different.

Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment of young and old.

What are people eating now? People are still eating food. They haven't yet started to take on heir(继承) supply of energy directly as electrical current or as nuclear power. They may some day. But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants.

Since there are several times as many people in the world today as there were a hundred years ago, most of our planet's surface has to be filled. The deserts are irrigated with water and crops are no longer destroyed by pests. The harvest is always good.

Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then.

We are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of diseases. No one has to be ill any more.

Such would be our life in 2060.

【推荐2】The other day, my sister and I were sitting in a restaurant, trying to have a conversation, but her children, four-year-old Willow and seven-year-old Luca, would not stop fighting. The arguments-over a fork, or who had more water in a glass-never stopped.

Then my sister reached into her handbag, produced two shiny iPads, and handed one to each child. Suddenly, the two were quiet. They sat playing games and watching videos, and we continued with our conversation.

After our meal, as my sister stuffed the iPads back into her bag, she said, “I don’t want to give them the iPads at the dinner table, but if they keep them occupied for an hour so we can eat in peace, I often just hand them over. I’m afraid it’s bad for them. I do worry that it makes them think it’s OK to use electronics at the dinner table in the future.”

Dr. Gary Small, director of the Longevity Center at the University of California, Los Angeles says that the brain is highly sensitive to stimuli (刺激物), like iPads and smartphone screens, and if people spend too much time on one technology, and less time interacting with people like parents at the dinner table, that could prevent the development of certain communication skills.

“Conversations with each other are the way children learn to have conversations with themselves, and learn how to be alone,” said Sherry Turkle, a professor of science, technology and society at the Massachusetts Institute of Technology. She fears that children who do not learn real interactions, which often have imperfections, will come to know a world where perfect, shiny screens give them a false sense of intimacy (亲密) without risk. However, they need to be able to gather themselves and know who they are. So someday they can form a relationship with another person without a panic of being alone. “If you don’t teach your children to be alone, they’ll only know how to be lonely,” she said.

1. According to Dr. Small, what should parents do?

A．Provide their children with various technologies.

B．Teach their children communication skills.

C．Talk to their children at the dinner table.

D．Limit their children’s screen time.

2. What is Sherry Turkle worried?

A．Children are afraid of taking risks.

B．Children try to escape from the real world.

C．Children can’t live without electronic devices.

D．Children can’t deal with companion-less situations.

3. What is the purpose of this text?

A．To tell a true story.	B．To discuss a phenomenon.
C．To give practical suggestions.	D．To compare different opinions.

【推荐3】When reading, my mother likes to slice a paragraph or a sentence out and attach it to the wall of her kitchen. She picks boring sentences that puzzle me. But I prefer copying favorite bright lines into a journal in soft, gray No. 2 pencil, word by word.

She doesn’t know any of this. There’s nothing shocking: for our chatting. We seldom begin certain conversations though we talk on the phone weekly, sometimes making each other laugh so hard that I choke and she cries. But what we don’t say could fill up rooms. Fights with my father. Small failures in school. Anything that really upsets us.

My mother has never told me “I love you, Lisa.” — as if the four-word absence explains who I am — so I carry it with me, like a label on me. The last time she almost spoke the words was two years ago, when she called to tell me a friend had been in hospital. I said, “I love you, Mom.” She stopped for a while and then said, “Thank you.” I haven’t said it since, but I’ve wondered why my mother doesn’t until I’ve found a poem that supplies words for the blank spaces I try to understand in our conversations:

Don’t fill up on bread. I say absent-mindedly. The servings here are huge.

My son, middle-aged, says: Did you really just say that to me?

What he doesn’t know is that when we’re walking together, I desire to reach for his hand.

It’s humble, yet heartbreaking. After copying it down in my journal, I emailed it to mom, adding “This poem makes me think of you.” My mother doesn’t read poetry — or at least, she doesn’t tell me, and I felt nervous clicking “Send”.

She never mentioned the poem. But the next time I went home for vacation, I noticed something new in the kitchen fixed to an antique board: the poem. The board hung above the heater, the warmest spot in the kitchen. The poem still hangs there. Neither my mother nor I have ever spoken about it.

What’s the function of paragraph 1?

A．To stress the theme.	B．To establish the setting.
C．To represent the characters.	D．To create the atmosphere.
