【推荐1】LONE TREE, colorado-patanjali Rao, a 15-year-old Colorado high school student and young scientist, who has used artificial intelligence （AI） and created apps to deal with social problems, has been named Time magazine's first-ever "Kid of the Year".

Time says Rao stood out for creating a world-wide community of young inventors and inspiring them to go after their goals. Rao insists that starting out small doesn't matter, as long as you have a passion （热爱）for it.

Rao's sense of invention started early. At age 12, she developed a portable device to discover lead in water. She has also created an app called Kindly that uses artificial intelligence to help prevent cyberbullying （网络欺凌）. It allows teens to type in a word or phrase to find out if the words they are using are bullying and lets them decide what they are sending.

She said that "Work is going to be in our generation's hands pretty soon. So if no one else is going to do it, I'm going to do it.”

Rao has partnered with schools, museums, and science, technology, engineering and math organizations, and other societies to work for thousands of other students.

In a world where science is increasingly questioned or challenged, Rao insists that devotion to science is an act of kindness and the best way that a younger generation can better the world. “We have science in everything we're involved in, and I think the biggest thing to put out there is that science is cool, innovating is cool, and anybody can be an innovator," Rao says.

"Anybody can do science.”

【推荐2】Israeli Company Develops 3D Printed Beef

If there were an award for the funniest company name of 2022, then the 3D printed meat company “Steakholder” would win that award.

Israeli company Steakholder Foods Ltd. has introduced its new product, Omakase Beef Morsels, which are bioprinted with cultured meat. The bites are inspired by the world-famous Wagyu beef, famous for its fat marbling patterns (大理石花纹) in the meat, which is also very expensive.

The company was formed in 2019 and has an office in Israel and Belgium, and is now expanding its operations to the US.     1    

Stakeholder uses stem cells from cattle for the production of its printed beef, and the muscle tissue and fat are printed from two separate bio-inks.    2     A bite can be made juicier, chewier, and the taste can also be altered.

    3     The cells are selected from animals that will provide the best meat and yield. The next step is proliferation, in which the cells are placed into a nutrient rich reactor to multiply. When the cells reach appropriate numbers, the stem cells change into muscle cells and fat cells.     4    

“This product marks a major step forward for us and for the cultured meat industry in general,” said Arik Kaufman, CEO of Steakholder Foods. “It is the result of a lot of hard work and our desire to achieve the highest level of meat possible through bioprinting and cell culture processes.”

    5     Its patent for 3D-bioprinting technology is the result of intensive cooperation between its 3D printing engineers and cell biologists. “We see Omakase Beef Morsels as the combination of food, technology and fine art,” Kaufman said. “We want to inspire chefs around the world to create delicious masterpieces and unforgettable dining experiences.”

So there you have it, guilt-free meat eating may be just around the corner.

A．The company has already achieved several milestones since it was founded.

B．Its goal is to create sustainable meat products to replace meats such as beef, chicken and even fish.

C．The layers of meat and fat can be regrouped in different proportions to create different flavor experiences.

D．Additionally, producing meat without having to raise and kill cattle may work out better for ensuring animal welfare and overall health.

E．The meat product is the first of its kind and was created using a specific 3D-bioprinting technology that was recently patented by the company.

F．In the final steps, the muscle cells and fat cells are turned into meat, ready to be processed into the final product, whether it’s a burger, steak, or even a meatloaf.

G．The process works by first selecting the animals to extract (提取) the stem cells from.

【推荐3】Oceans are an appealing target for renewable energy generation. Waves alone produce 32,000 terawatt-hours of natural energy per year—for reference, the entire world uses around 23,000 terawatt-hours annually. And there is also the power of currents and tides(潮汐) energy.

The advantages of wave power are clear. Basically, wave energy does not emit greenhouse gases when generated, like fossil fuels do. Turbines(涡轮机) generate electricity through the power of waves, making them a completely pollution-free, renewable energy source. And the amount of power that is produced in a wave is huge-that energy then gets captured by wave energy converters(转换器) to produce electricity. There is also a lot of potential because many countries have access to an ocean that can help power their electric grids. Also, waves are hardly interrupted and almost always in motion. This makes electricity generation from wave energy a more reliable energy source compared to wind power, since wind is not constantly blowing.

But the disadvantages of wave energy are serious too. Building plants or electrical wires directly on the beach might prove challenging because they would be unsightly and can cause damage to marine life and the surrounding ecosystems. Local fishing zones could be affected or the plants could lead to more coastal corrosion(腐蚀). High costs is a problem too. Wave power is an emerging energy technology in the early stages of development, making working out costs difficult. Maintenance for these plants is projected to be very expensive because they will be submerged in constantly-moving saltwater. Because constant movement can lead to more breaking, wave energy plants will most likely need regular(and costly)maintenance.

Despite the challenges, there is a future of wave energy. For many ocean-bordering countries, wave energy could be a great addition to the renewable energy mix. The bottom line is that wave power has huge global potential. However, the industry needs more funding and research to finalize the technology involved so that countries and governments can begin adding wave energy to their renewable energy collection.

1. What makes wave power more reliable compared to wave power?

A．Being huge in amount.	B．Being environmentally friendly.
C．Being almost always on the move.	D．Being accessible to many countries.

2. Why is it difficult to calculate the costs of wave power plants?

A．The plants are still in the initial stage.

B．The plants will ruin the neighbouring scenery.

C．It will cost much to maintain their functions.

D．The plants will cause damage to the ecosystems nearby.

3. Who is the text most probably intended for?

A．Students concerned about marine life.	B．Governments attracted by wave energy.
C．Teachers focusing on coastal ecosystems.	D．Scientists interested in renewable energy.

4. What is the author’s attitude toward wave energy?

A．Critical.	B．Reserved.
C．Supportive.	D．Doubtful.

【推荐1】A raised eyebrow, a puzzled look or a nod of the head are just a few of the facial expressions computers could soon be using to read people’s minds.

An emotionally aware” computer being developed by British and American scientists will be able to read an individuals thoughts by analyzing a combination of facial movements that represent underlying feelings.

“The system we have developed allows a wide range of mental states to be identified just by pointing a video camera at someone, “ said Professor Peter Robinson of the University of Cambridge.

He believes the mind-reading computer’s applications could range from improving people’s driving skills to helping companies tailor advertising to people’s moods(心情).

“Imagine a computer that could pick the right emotional moment to try to sell you something, a future where mobile phones, cars and Web sites could read our mind and react to our moods,” he added.

The researchers, who are developing the technology at the Massachusetts Institute of Technology in the United States, also hope to get it to accept other inputs such as posture(姿势)and gesture.

“Our research could enable Web sites to tailor advertising or products to your mood,” said Robinson. “For example, a Webcam(网络摄相机) linked with our software could process your image, encode the correct emotional state and send information to a Web site.” It could also be useful in online teaching to show whether someone understands what is being explained and in improving road safety by determining if a driver is confused, bored or tired.

“We are working with a car company, and they believe this will be employed in cars within five years,” Robinson said, adding that a camera could be built into the dashboard(仪表板).

1. Why is the computer described as “emotionally aware”?

A．It can store your thoughts.	B．It can express its feelings.
C．It thinks the same way as you.	D．It knows what you are feeling.

【推荐3】A group of sweaty kids ran around a field last week at Total Soccer Arena in Landover, Maryland. They talked in English,but also in Pashto, Arabic and other languages.

What made them different is that all of the kids are refugees(难民). They were playing as part of a camp that gives them a chance to develop their soccer skills and to meet other kids who had to start their lives over in the United States. The camp is run by an organization called LACES, which stands for Life and Change Experienced through Sports. The group uses soccer to help bring together communities that have experienced hardships.

SerenFryatt, 38, got the idea for LACES while playing on a women's soccer team in Liberia,an African country that had been at war with itself for 14 years. Fryatt, who's from Muncie, Indiana,saw that soccer brought joy to the Liberian women on her team,even though their lives off the field were very difficult. After starting a soccer program for kids in Liberia,she decided to start a similar camp in Maryland,where she moved in 2015. Coaches volunteer their time, and the costs are paid mostly by donations(捐赠). This year, 95 kids signed up.

The camp, for ages 9 to 14, is split(分组) between training that helps kids develop skills, such as passing and ball control, and meeting where they discuss life skills. One of the coaches, Louisa Pitney, said she likes seeing how the kids grow just from being together.

At the end of the camp's last day, all the kids gathered in the middle of the field. Fryatt asked them to raise their hands and say what they had learned that week. Some kids talked about soccer skills-one girl said she'd learned not to use her hands; a boy said he'd learned how to score a goal.

When a coach called on one shy girl, she smiled before answering in a soft voice.

“Celebrate each other, "she said.

【推荐1】Helping voters out

The US 2020 presidential election has captured people’s hearts around the world. In order to allow voters to vote in person, poll (投票站) workers need to work at different vote centers. In past elections, most poll workers were elderly, but now that they are more at risk of severe symptoms from COVID-19, there was a growing need for young people to serve as poll workers.

I first became aware of the opportunity to become a poll worker from a story on my Instagram feed from an account called “Poll Hero”. It mentioned a large-scale recruitment (招聘) effort for young poll workers, and I immediately became interested in participating. I signed up to be a poll worker from the website, and a few days later, I registered through the High School Student Election Worker Program with the assistance of a Poll Hero volunteer.

After registering, there were two steps I had to take in order to become certified to serve in this election. The first was an online training course. The course takes around three hours but can be completed in multiple sittings. It covers the different roles workers have, different procedures workers must follow and provides information on how to use tools such as the electronic pollbook. The session is interactive, and I often engaged in simulated (模拟的) situations and knowledge checks to ensure that I understood each lesson. After taking the online course, I had to pass an exam with an 80 percent score or higher to complete that part of my certification. On my first attempt, I passed with a score of exactly 80 percent.

After passing the online course, I attended a two-hour in-person training session where I worked with a real electronic pollbook to practice what I would do on Election Day. The instructor took us through many different scenarios where we practiced assisting different types of voters. I was pleased to see many fellow young people attend the session!

In total, I spent 37 hours helping voters vote during this election. With my mask on the entire time, I checked in voters and helped them use the ballot (投票) marking devices where they could cast their vote. I also loved meeting fellow workers who are passionate about being engaged and helping our community. Taking part in this historic election is something I will never forget.

【推荐2】The Plastic Bottle Village is just a great idea that might finally help people protect the environment. It’s a village in Panama that is going to be made of used plastic bottles.

The village will include about 120 homes of different sizes. The design begins with building structures of steel(钢铁)，which are then filled with these bottles. Once this step is complete，and electrical lines are put inside，the plastic walls are covered by concrete(混凝土)—both inside and outside. So no one will actually be able to tell that the walls are made of plastic. Besides，the material will keep the house 17 ℃ cooler than the temperature outside，which is the biggest advantage to people living inside.

The village is the work of Robert Bezeau with the purpose of setting up some environmental projects. Having started a recycling program in 2012，during which a number of plastic bottles were collected，he started to think how they could be put to use. Soon enough，he decided to use them to build houses.

Over 10，000 plastic bottles were used to build the first house，which was completed late last year. The bottles were gained from the same recycling project that Robert had set up. The next home is expected to be bigger，and will need more bottles. The special homes will be sold on request for anywhere between $149，000 and $300，000. The village will also feature its living environment，such as gardens，mini－parks，and more.

22，000 plastic bottles are thrown away around the world per second. While all these bottles clearly cannot be reused into homes，the project hopes to raise the attention of the waste. The village will also create an education center that will teach people from the world how to reuse plastic bottles as building materials.

1. What is so special about the homes in the village?

A．They can stop people from being cold.

B．They are built out of plastic bottles.

C．They are being built by famous artists.

D．They are sold for anyone from anywhere.

2. The biggest advantage for the people living in the special houses lies in ________.

A．the cool temperature

B．environmental protection

C．cutting down the cost

D．different sizes

3. We can infer from Paragraph 3 that Robert Bezeau is________.

【推荐3】Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.

How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.

“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone,” says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers’ bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.

Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am. Students, parents and teachers are pleased with the results.

1. What is the general idea of the first paragraph?
