1 . Lapland's reindeer (驯鹿) grow well in winters of -30℃ and even colder. So when rain falls instead of snow during the coldest months in the Arctic,it makes food hard to get for them. Now one of the best-loved symbols of Christmas is probably dying out. Numbers have fallen by over half in the last two decades as the place warms at four times the global average rate.

The animals are used to pull sleigh (雪橇) rides for tourists. The rides are part of Lapland winter wonderland experiences in thousands of British tourists each year. But this year the working herd had to be moved 60 miles further north due to the absence of snow. As a result, they can't be provided in some areas, making it hard for people to earn a living.

Lapland is often described as Europe's last great wilderness, home to lynxes, brown bears, wolverines and golden eagles. Tourism is a big part of the economy, and the town of Rovaniemi is also the "official home of Santa Claus". But changing climate (气候) is threatening its tourism industry. A report by The Finnish Climate Change Panel warns of flooding and increased rainfall, with Rovaniemi most at risk. Firms that rely on snow "will have great effects on visit levels" and these industries may be forced further north.

Erkkila of the Arctic Husky Park in Rovaniemi says: "Tourists see pictures of the Santa Claus village covered in snow and when they get here they think, 'Is this the winter wonderland?'." The Husky Park bought a wheeled cart (车) six years ago as a replacement for sleigh rides when the snow fails.

In the past it was thought the Arctic was warming twice as fast as the rest of the world. But a report published last week by scientists showed the rate is actually four times the global average.

2 . Mr Jason has taught math in a remote rural area for ten years. Last year, he was awarded (奖励) $2,000 as “The Amazing Teacher”. People thought he would move with his parents to a nice house in the city. But he surprised then all. When students came back from their holiday, they found the chairs, desks and projectors (投影仪) were all replaced. Even the walls of the classroom were painted white.

As a teacher, Mr Jason not only focuses on students’ studies, but also helps students overcome the difficulties in life. In the rural area, most families are poor and some students often dropped out of school. Mr Jason always tries to help then out.

When interviewed, he said, “When I was in middle school, a Mr Smith helped me until I graduated from university. I attempted many times to find him after graduation, but failed. I thought maybe what he most wished was not my thankfulness but another Mr Smith. So I am here.”

“Mr Jason is the best teacher I have ever had. Without his help, my whole life would end in the village. When I was in Senior Two, my family couldn’t afford my tuition (学费) so I stayed at home. At that time, I felt hopeless. It was Mr Jason who asked my parents to send me back to school. Luckily, I was admitted into my ideal university finally,” said Julia, a fresh college student. “Now, I believe the road                           ahead is promising.”

Mr Jason’s goodwill touches many people. When the activity “The Amazing Teacher” was launched, someone posted his story on the Internet. And it soon spread over.

Later, Mr Jason wrote: I just have done what a teacher should do. I hope people could pay attention to those children in need and help them realize their dreams.

In Budapest, a train line called Gyermekavasut runs between stations     1     (bury) deep in the woodland. Like any other railway, it has ticket offices, signals, guards and a timetable. Unlike any other, this one     2     (run) by children aged between 10 and 14. The children of the Gyermekavasut railway     3     (efficient) sell and check tickets and salute trains as they leave     4     (station).

In fact, the railway was created to give children the chance to learn teamwork and     5     (responsible). Kids work the railway under     6     guidance of adults, and the engineers and the train drivers are adults.

Tickets can be bought from a child who usually takes the job so seriously. As the train comes in, a childish voice echoes (回响) in the station following the same jingle (叮当声) that can be heard in every station across Hungary. The train     7     (pull) out, as children in navy blue uniforms with red caps salute. Once the train leaves the platform, they relax back into more natural childlike poses.

Only the top students are considered for the railway, and those selected     8     the job take a training course and must pass railway worker exams. For a year, the railway children go on duty every two weeks,    9     (get) excused from school during workdays, but only on the condition     10     their grades don’t slip.

5 . Since the beginning of my scientific training, I was encouraged to seek multiple mentors (导师) to help me find my way. With many efforts, I became comfortable, confident, and strategic in building my network of mentors.    1    

Cast a wide net.

Sending cold contacts was scary, so I focused on the thrill of emailing people who had some of the coolest jobs I'd ever heard of. If I was inspired by someone's work, I emailed. If

I loved the way they ran their lab, I emailed. If I was interested in learning more about their company, I emailed.     2     At last, I got dozens of informational interviews that helped me in my ideal job.

    3    

As a grad student, I met someone at a conference who I hoped would be a future mentor—and followed up with a five-paragraph email. Their reply was simple, “I cannot respond to this. Too long.” Over the years, I learned to clearly include the what, the ask, and the when —for example, a 30-minute meeting to talk about X, offering three or four specific times. A clear, concise email encourages a quick, positive response.

Consider the context (情景).

In graduate school, I asked a senior faculty member to serve as my departmental adviser.     4     A few months later, he left the institution. I realized the move must have already been in the works when I asked, and his response didn't reflect negatively on me; he was just predicting his own changing circumstances. When evaluating responses or advice, remember that everyone has their own affairs and concerns.

Come prepared.

    5     I came to every conversation with at least 10 questions, arranged in categories including shared experiences, career goals, and advice. Coming prepared helped me respect other people's time and use these meetings wisely.
