As the Arctic thaws，can science help to chart a sustainable path for the north?
Last winter，parts of the Canadian Arctic basked in recordbreaking warmth. In the town of Coral Harbour，at the mouth of Hudson Bay，temperatures rose above freezing for a few days in January for the first time ever.Across the Arctic，extreme climate conditions are becoming the norm，even as the region faces other profound changes，such as the growing political power of local people and the race to extract mineral resources (see page 172)．
This week，Nature examines how these changes are affecting scientific access to the north (see page 174)，and what scientists should do to keep Arctic development green (see page 179) and peaceful (see page 180)．Some are calling for international regulations to safeguard the environment as ship traffic increases (see page 157 )．Both research and development need to consider the views of local people，and scientists are learning how to do so (see page 182)．Locals can provide insight into environmental changes.
There is a long tradition of international scientific cooperation in the Arctic.That tradition must be preserved and expanded，even as nations in the region push forward with territorial claims under the UN Convention on the Law of the Sea. Countries should work together，perhaps through the Arctic Council，to ensure that researchers from all nations are allowed access to all parts of the Arctic Ocean.
At the same time，scientists should make their data available in public databases as soon as possible after collection.The far north is changing faster than anywhere else on earth，with potentially vast impacts on climate as carbonrich permafrost melts，and dark ground and water exposed by the retreating ice soak up more heat from the Sun.It is crucial that science keeps up.
Siri is an artificial intelligence (AI) that you can carry around in the pocket, where it waits patiently to be told what to do. In the week we spend together, my AI assistant has performed admirably in finding me restaurants, or the location of the nearest coffee shop.
A typical command might be: “Reserve a table for two at a good French restaurant in San Francisco.” Siri responds by presenting a list of top-rated restaurants that can be booked on OpenTable.com. If you say which time you want, it can book you a table without your lifting a finger. In some ways Siri is just a fancy program to the 35 websites it can connect to, from taxi booking websites to movie review databases (数据库). But what's new is the way it can analyze the intentions of its users and use those sites to put them into action.
Siri attaches possibilities to the explanation of each word and compare your location with other data, some of which you must provide yourself. To send email reminders, Siri obviously needs to know your email address. To “find me the flower shop closest to work”, it needs to know where you work. To pay bills or buy airline tickets, it would need to be linked to your credit card.
That raises the question of how far we are willing to trust a piece of software that can go and do things for us based on what it “thinks” we mean. Siri may be simple, and always shows its explanation of a command before carrying it out. But it gives users a preview of a new balance between privacy, trust and convenience that the expansion of AI into everyday life is likely to develop.
One early morning, I went into the living room to find my mother reading a thick book called Best Loved Poems to Read Again and Again. My interest was aroused only by the fact that the word ＂Poems＂ appeared in big, hot pink letters.
＂Is it good?＂ I asked her.
＂Yeah,＂ she answered. ＂There's one I really like and you'll like it, too.＂ I leaned forward.
＂‘Patty Poem,'＂ she read the title. Who is Patty? I wondered. The poem began:
She never puts her toys away,
Just leaves them scattered①where they lay,… ①散乱的
The poem was just three short sections. The final one came quickly:
When she grows and gathers poise②, ②稳重
I'll miss her harum-scarum③ noise, ③莽撞的
And look in vain④ for scattered toys. ④徒劳地
And I'll be sad.
A terrible sorrow washed over me. Whoever Patty was, she was a mean girl. Then, the shock.
＂It's you, honey,＂ My mother said sadly.
To my mother, the poem revealed a parent's affection when her child grows up and leaves. To me, the ＂she＂in the poem was horror. It was my mama who would be sad. It was so terrible I burst out crying.
＂What's wrong?＂my mother asked.
＂Oh Mama,＂I cried.＂I don't want to grow up ever!＂
She smiled.＂Honey, it's okay. You're not growing up anytime soon. And when you do, I'll still love you, okay?＂
＂Okay,＂I was still weeping. My panic has gone. But I could not help thinking about that silly poem. After what seemed like a safe amount of time, I read the poem again and was confused. It all fit so well together, like a puzzle. The language was simple, so simple I could plainly understand its meaning, yet it was still beautiful. I was now fascinated by the idea of poetry, words that had the power to make or break a person's world.
I have since fallen in love with other poems, but ＂Patty Poem＂ remains my poem. After all, ＂Patty Poem＂ gave me my love for poetry not because it was the poem that lifted my spirits, but because it was the one that hurt me the most.
Do you still remember your favorite poem from high school or some other important periods in your life？Why is it that decades later it still stands out in your mind？Probably the main reason is that some aspect of that poem resonates (引起共鸣) with you. In the same way, you too as a school leader can touch the hearts of your teachers and students.
Poetry allows us to experience strong spiritual connections to things around us and to the past. The power that poetry has displayed over time and across cultures actually satisfies this common need of the human heart and soul.
As one of the oldest art forms, poetry has successfully connected various parts of humanity (人性) from one generation to another. Referring to poetry, Hillyer makes a simple yet meaningful statement, “With this key mankind unlocked his heart.”
School leaders can find and make use of the value of poetry for themselves, their students and their teachers. Beyond the simple use of poetry, techniques of poetry such as repetitions can be used to take advantage of the power of language to transform communication, create meaning and a culture of care and attention.
Since schools are mainly about people and relationships, school leaders, like poets, are required to inspire and encourage the human heart. The use of poetry—or even of some techniques of poetry—in school leadership not only helps to improve communication, but also serves to meet the human need for inspiration.

Several countries in Asia celebrate the Lunar New Year in their own way. But dragon and lion dances in Chinatowns all over the world have helped to make China's New Year the most famous. These days growing (number) of people who are not of Chinese origin are joining in. In Tokyo window cleaners dress up like the animals of the Chinese Shengxiao. America, Canada and New Zealand have published memorial stamps for the year of the rooster. Last year New York City made the Lunar New Year school holiday for the first time.
The spread of the Spring Festival is (part) due to recent immigration from China: 9.5 million Chinese people (move) abroad since 1978, many of are far richer than earlier waves of immigrants.
Aware China's growing economic and political influence, foreign leaders have noticed the occasion. Britain's prime minister, Theresa May, has given a video address, a tradition (start) in 2014 by her predecessor (前任) . This year's World Economic Forum in Davos was held a week earlier than usual (avoid) conflicting with China's New Year.
China hopes the festival will promote (it) cultural “soft power” abroad. It may give the Chinese people (satisfy) to see foreigners enjoy such festivities.
Rome wasn't built in a day, and the Internet didn't come out of a golden egg. Many of today's creations were not born of people who had creative ideas, but who did not stop at simply having an idea. They took one brick of capital (资本), another brick of knowledge, perhaps a brick or two of family and friends, and built their empires (帝国) brick by brick.
If you want to build an online empire, you cannot settle for simply having a website full of articles, or a website full of pictures—there are already thousands of sites like that, so you need to come up with something new and creative.
So if you are starting to build something up, ask yourself: what do you really want to do, and what are you really good at? Believe it or not, you can make money at something that you are an expert in, and you need to know what that is.
Remember, having an online empire does not mean that you have to do it alone. You can take your friends along with you. Having a friend advertise your services online is a good way to attract more visitors to your empire.
Building an online empire, you will have to be prepared to not only come up with creative ideas, but to carry your ideas through. Talk to people who have already succeeded in building their own empires. Talk to people who are struggling. Join a mailing list that will help you get through your struggle to achieve your goal.
As you move forward, you will find that you can help other people, and you will have a good many stories to tell—not to mention a lot of money in the bank.
If you learn the real secrets of creating a long term stable (稳定的) online business then you will have enough money to retire on.

Two years before, I traveled to Brazil and I rented for a car. Unfortunate, I had an accident and hit another car, and I needed to stay in a hospital for at least two week. I called my parents, so I did not tell them what had happened. I knew that they will be worried about myself because I was so farther away, and that my mother would not sleep if she knew. Therefore, I told them interested stories and how I was enjoying Brazil. As a result, nobody knew truth. I still think that it was the right thing to do.
