1 . On many travelers’ lists of things to do before they die, you’ll find “See the northern lights” written down. Rightfully so these lights are one of nature’s most jaw-dropping views.

In Sweden, the northern lights usually appear from late March or early April. Your best chance of catching a glimpse of them is on cold winter nights when the sky is clear, dark with little to no moonlight, and cloudless. You need to be away from city lights and go to the countryside. For those willing to brave the cold on winter nights, here are some of the best locations.

Abisko National Park

Abisko Natinal Park is a main location. The scientifically confirmed “blue hole”, a piece of sky over the Tornetrask lake that usually remains clear despite cloudy weather nearby, gives Abisko its own microclimate (局部地区气候), which is suitable for catching the lights.

Jukkasjarvi

The village of Jukkasjarvi only has about 550 people. But don’t let the small population size fool you: Jukkasjarvi owns the world’s first ice hotel and is one of the best places to view the northern lights. The ice hotel organizes guided tours for guests to the Esrange Space Center. There you can eat at a camp outside and see the Arctic winter sky for aurora borealis (北极光). Or why not try to get closer to the northern lights and watch them through an aeroplane window? The ice hotel arranges flights for the amazing northern lights experience.

Gallivare

You can drive a snowmobile to the mountain top in Gallivare for a private light show, or head a few kilometers to nearby villages to watch those lights shining across the dark winter sky. But remember if you do get the chance to see the northern lights in person, never whistle to them. According to ancient Sumi fairy, it brings you bad luck.

Later, my father ________ to me: There’s no such thing as a free lunch. So it’s ________ to ask for a payment after taking photos for us. But if someone offers to help you, never ________ the kindness just because of this particular event. Most acts of kindness are pure and without any ________ intention.

________, we met a lot of warm-hearted locals who guided us and lent a hand when we needed them. So just remember, we can’t throw away the ________ because of its core.

3 . Every year about 40,000 people attempt to climb Kilimanjaro, the highest mountain in Africa. They bring with them lots of waste. The_________ might damage the beauty of the place. The glaciers (冰川) are disappearing, changing the_________ of Kilimanjaro.

Hearing these stories, I’m_________ about the place — other destinations are described as “purer” natural experiences.

However, I soon discovered that much has changed since the days of disturbing reports of_________ among tons of rubbish. I find a clean mountain, with toilets at camps and along the paths. The environmental challenges are_________ but the efforts made by the Tanzania National Park Authority seem to be_________ .

The best of a Kilimanjaro_________ , in my opinion, isn’t reaching the top. Mountains are regarded as spiritual places by many cultures. This_________ is especially evident on Kilimanjaro as climbers go through five ecosystems (生态系统) in the space of a few kilometers. At the base is a rainforest. It ends abruptly at 3, 000 meters,_________ lands of low growing plants. Further up, the weather__________ — low clouds envelope the mountainsides, which are covered with thick grass. I __________ twelve shades of green from where I stand. Above 4, 000 meters is the highland __________ : gravel (砾石), stones and rocks. __________ you climb into an arctic-like zone with__________ snow and the glaciers that may soon disappear.

Does Kilimanjaro deserve its__________ as a crowded mountain with lines of tourists ruining the atmosphere of peace? I found the opposite to be true.
