I've always loved the ocean. In the    1     (seven) grade,I started volunteering at the Monterey Bay Aquarium in California. I was upset to learn that many sea animals eat plastic garbage,     2     (think)it is food.

I decided to do something     3     (educate) people about this problem. I held presentations at schools to teach kids about plastic waste. I wanted to reach businesses too. I decided that if I learned of a company    4     used a lot of plastic, I'd send it an email urging it to cut back.

One day, I saw a commercial for a health-care company. People in the ad were using plastic straws （吸管）.   I found the contact information of the company    5     emailed its president. I told him how     6     (harm) plastic could be to the environment and asked him to consider using more eco-friendly options. I was so    7     (excite) when he wrote back to me.He said he would make sure that the company cut its use of plastic straws in half.

I kept going. Whenever I heard of businesses using plastic, I'd send an email. One of the biggest companies I wrote to     8     (be) Alaska Airlines Paris. A company     9     (represent) wrote back and told me the airline was switching over     10     plastic to paper cups on all of its 1,200 daily flights.

3 . An Australian professor is developing a robot to monitor the health of grazing cattle, a development that could bring big changes to a profession that's relied largely on a low-tech approach for decades but is facing a labor shortage.

Salah Sukkarieh, a professor at the University of Sydney, sees robots as necessary given how cattlemen are aging. He is building a four-wheeled robot that will run on solar and electric power. It will use cameras and sensors to monitor the animals. A computer system will analyze the video to determine whether a cow is sick. Radio tags (标签) on the animals will measure temperature changes. The quality of grassland will be tracked by monitoring the shape, color and texture (质地) of grass. That way, cattlemen will know whether they need to move their cattle to another field for nutrition purposes.

Machines have largely taken over planting, watering and harvesting crops such as com and wheat, but the monitoring of cattle has gone through fewer changes.

For Texas cattleman Pete Bonds, it's increasingly difficult to find workers interested in watching cattle. But Bonds doesn't believe a robot is right for the job. Years of experience in the industry - and failed attempts to use technology - have convinced him that the best way to check cattle is with a man on a horse. Bonds, who bought his first cattle almost 50 years ago, still has each of his cowboys inspect 300 or 400 cattle daily and look for signs that an animal is getting sick.

Other cattlemen see more promise in robots. Michael Kelsey Paris, vice president of the Oklahoma Cattlemen's Association, said a robot could be extremely useful given rising concerns about cattle theft. Cattle tend to be kept in remote places and their value has risen, making them appealing targets.

4 . A British woman who won a S1 million prize after she was named the World's Best Teacher will use the cash to bring inspirational figures into UK schools.

Andria Zafirakou,a north London secondary school teacher, said she wanted to bring about a classroom revolution (变革). “We are going to make a change, ”she said.“I’ve started a project to promote the teaching of the arts in our schools.”

The project results from the difficulties many schools have in getting artists of any sort - whether an up-and-coming local musician or a major movie star - into schools to work with and inspire children.

Zafirakou began the project at Alperton Community School, her place of work for the past twelve years. “I've seen those magic moments when children are talking to someone they are inspired by - their eyes are shining and their faces light up,” she said. “We need artists . more than ever in our schools."

Artist Michael Craig-Martin said: “Andria's brilliant project to bring artists from all fields into direct contact with children is particularly welcome at a time when the arts are being downgraded in schools." It was a mistake to see the arts as unnecessary, he added.

Historian Sir Simon Schama is also a supporter of the project. He said that arts education in schools was not just an add-on. “It is absolutely necessary. The future depends on creativity and creativity depends on the young. What will remain of us when artificial intelligence takes over will be our creativity, and it is our creative spirit, our visionary sense of freshness,that has been our strength for centuries."

Most of us associate learning with younger people—kids in school and college or recent graduates early in their careers. But at Udemy, an open university offering online courses, Artist Anneke Camstra is engaged in the pursuit of lifelong learning and displays her potential for teaching. She loves the experience of gaining new knowledge and also loves sharing it with others. “I’m retired, but an artist never retires,” Anneke said. “The last few years on the internet have been a great joy for me. I’ve taken so many Udemy courses, and ifs such a great feeling to get my brain working again. I find just as much satisfaction in teaching animation(动画制作)too.”

She reaches countless people with her online courses and exposes them to what they can accomplish on their own using animation software, such as GoAnimate and PowToon. Her motivation for teaching on Udemy is “to get the tools to the people.”“You can go such a long way to make things that look professional but still have your own voice,” she explained.

Most of Anneke’s students start out thinking they’re not creative and can’t draw. Anneke understands how fear can get in the way of so many things people dream of doing. With her five-day challenge courses, she helps them get over the fear. Anneke loves the impact she has on her students. What makes her more proud of them is that they have gone from their first animation to creating their own works.

She encourages people of all ages, especially older people, to cultivate their curiosity for life. Grandparents, for example, can learn to use GoAnimate and make animations together with their grandkids.

“Tm an older woman, teaching and having fun learning again,” Anneke said, and she wants others later in their lives to catch up with her on this journey.

7 . Art is everywhere. Any public space has been carefully designed by an artistic mind to be both functional and beautiful. Why, then, is art still so widely considered to be "the easy subject" at school, insignificant to wider society, a waste of time and effort?

Art can connect culture with commercial products in a way that not many other things can; art generates money and holds significant emotional and cultural value within communities. When people attend a concert, they are paying for music, sure, maybe even hotel rooms, meals, and transport, but they also gain an incredible experience, a unique atmosphere and a memory that will go through the rest of their lives. People don't just want material things anymore, they want to experience life一the arts are a perfect crossover（交迭）between culture and commerce.

Furthermore, the arts can bring communities together, reducing loneliness and making people feel safer. Social bonds are created among individuals when they share their arts experiences through reflection and discussion, and their expression of common values through artworks in honour of events significant to a nation's experience.

The arts clearly have a pretty positive impact on physical and psychological health. It is found that people who frequent cultural places or participate in artistic events are more likely to gain good health compared to those who do not; more engagement with the arts is linked to a higher level of people's wellbeing. The Royal Society of Public Health discovered that music and art, when used in hospitals, help to improve the conditions of patients by reducing stress, anxiety and blood pressure.

Children who are involved with the arts make greater achievements in their education: those engaged with drama have greater literary ability while others taking part in musical practice exhibit greater skills in math and languages. Kids with preference for the arts have a greater chance of finding employment in the future. Participating in the arts is essential for child development; encouraging children to express themselves in constructive ways could help to form healthy emotional responses in later life.

Vital to human life, art is celebrated and used by nations across the world for various purposes. Life without art would be boring and dead still, for art is a part of what makes us human.

8 . In the fictional worlds of film and TV, artificial intelligence （AI） has been described as so advanced that it is indistinguishable from humans. But what if we're actually getting closer to a world where Al is capable of thinking and feeling?

Tech company UneeQ is heading for its "digital humans", which appear life like on the screen not only in terms of language, but also because of facial movements: raised eyebrows, a smile, even a nod. They look close to a human, but not quite.

What lies beneath UneeQ9 s digital humans? Their 3D faces are modeled on actual human features. Speech recognition enables them to understand what a person is saying, and natural language processing is used to work out a response. Meanwhile, another Al company, Soul Machines, is taking a more biological approach, with a "digital brain", that imitates aspects of the human brain to adjust the emotions "felt" and "expressed" by its "digital people".

Shiwali Mohan, an Al scientist at the Palo Research Center, is skeptical of these digital beings. "They're humanlike in their looks and the way they sound, but that in itself is not being human," she says. "Human qualities also involve how you think, how you approach problems, and how you break them down; and that takes a lot of algorithmic (算 法)design. Designing for human-level intelligence is a different attempt than designing images that behave like humans." She then continues, “If something looks like a human, we have high expectations of them, but they might behave differently in ways that humans just instinctively (直觉地)know how other humans react.

Yet the demand is there, with UneeQ seeing high adoption of its digital employees across the financial, health care, and commercial sectors （行业）. "Unless these sectors make their business models much more efficient digitally, they might be left behind," says Chetan Dube, UneeQ9s CEO.

Some other companies are taking their digital beings a step further, enabling organizations and individuals to create digital humans themselves using free-access platforms they provide. "The biggest motivation for such platforms is to popularize Al," Dube says.

Mohan is cautious about this approach, yet she supports the purpose behind these digital beings and is optimistic about where they are headed. "As we develop more advanced Al technology, we would then have to use new ways of communicating with that technology,she says. "'Hopefully, all of that is designed to support humans in their goals."

Recent research suggests that if an argument gets resolved，the emotional response tied to it is significantly reduced or almost completely erased．Thus，it may be worth bringing up issues with your friends， family members，or classmates rather than holding them back．

There is a difference between arguing and fighting．Arguing is that you and your opponent present your concerns and discuss the feelings and issues related to those concerns．You can engage in an argument respectfully without stirring up（激起） anger．Fighting，however，usually involves personal attacks，raising of voices， and storming out．Discussing your issues and resolving them instead of stuffing them down can improve your emotional health．In a study，2.000 people were asked to record their feelings and experiences for eight days in a row．When people had an argument that they considered resolved， they had half the reactivity （情绪反应） of those who avoided an argument．Reactivity is an increase in negative emotions or a decrease in positive emotions．In other words，resolving an argument cuts your negative feelings by half．One day later， people who had a resolved argument reported no increase of negative emotions compared with those who avoided an argument． This means that resolving an argument can feel like you have reached a state of resolution——and you are less likely to be annoyed．

Moreover，the older you are，the more likely you will come to a resolution after an argument．This may be because more life experience usually leads to more defined priorities．You are more likely to distinguish between what matters and what does not．

It is easier to avoid a discussion，but risking talking about it may eventually lead to a better outcome．

10 . Music has long been considered to be an enjoyable pastime for many people．     1     The mental health benefits from music can't be argued．Music could also be helping you with many other health problems behind the scenes．

    2    However，for the same reason，music can be very beneficial if one is in pain．By distracting （分心） the mind from the pain，music，people say，can lower stress and anxiety levels．This，of course，can lead to less pain．

Many people enjoy relaxing music in the evening prior to going to bed．    3    While the validity of the idea is still being assessed，the lowered stress can even be tied back to blood pressure．Similarly, according to researchers，listening to just 30 minutes of soft music every day may help with healthy blood sugar levels， through the lowering of stress and anxiety．

When it comes to heart health，there is speculation （推测） that it's not the style of music， but rather the tempo that makes it so good for your heart health．In one European study，participants listened to music as the researchers monitored their heart rates and blood pressure．    4     On the other hand，when the music slowed，the participants' stress and anxiety levels became lower and the effects on heart rates appeared to follow suit．

    5    But there is a whole range of other health issues that turning up the radio could be beneficial for，which is what makes music so valuable．
