Christmas Island, which is barely a tiny spot on the world map, sits about 250 miles south off the coast of Central Java, and 1,650 miles from Perth, the nearest western Australian city. Technically, it’s part of Australia, but you’d never know from its location.
Christmas Island got its name from Captain William Mynors, an English sailor who accidentally landed on this unknown land on Christmas Day in 1643, though it wasn’t until the late 1800s that the island was properly surveyed.
With its warm temperatures and high rainfall, Christmas Island is home to all sorts of wildlife. Nearly two-thirds of the island is national park land, which is highly popular with bird-watchers.
No matter where you end up in the forest, you won’t be short on sightseeing spots. Hugh’s Dale Waterfall is eye-catching, and can only be reached by hiking through the rainforest. Once you arrive at the falls, go ahead and take a shower under the crashing water — not only is it clean enough to drink, it’s held sacred(神圣的) by local Buddhists, who believe it’s the center of the island’s "water universe."
Most people come for the beaches. Since the island is so small and has remained in its natural state for so long, all kinds of colorful fish can be found swimming around the island’s tropical reef. You might find yourself swimming with the world’s largest fish, the whale shark, which visits Christmas Island from November to April.
To get to Christmas Island, you’ll need to fly in from Perth or Fiji. Click here for more information.

【推荐1】What I’ve been wondering is:
Read books and watch movies that transport you
One of my favorite things to do before taking a trip is to search out books and movies that can help me get a feel for a place.
Music is deeply connected to our emotions, which makes it particularly transporting. The beautiful sounds of Sigur Rós, for example, can create a dreamy atmosphere. Hawaiian ukulele and hula music bring the beach to your living room. Try searching for artists or genres of music from your desired destination and build a playlist to help you set the atmosphere.
Visit a museum — virtually
Museums in many locations have started to reopen with social distancing and masks, but if you’re not ready to go in person, you can spend an afternoon exploring them online. Google map has digitized hundreds of collections and online tours at museums around the world.
Tour a national park
Camping is one type of vacation that’s mostly safe and accessible to do right now. But if you can’t get to the great outdoors, bring the outdoors to your home.
If you don’t have the budget or time to travel right now, try layering a few of these ideas together to create a kind of at-home immersion(沉浸感).

【推荐2】In the UK we often equate life experience, especially amongst younger generations, with the number of stamps in your passport. Travel is not simply a pursuit of leisure but also “character-building”, “defining” and potentially, “career-boosting”.
Most of the people I know here at university experience that same itch to get in a plane, train, bus or car and escape the hectic stress of deadlines and seminars that usually surrounds us. But I don’t think, as UK student, we can blame our addiction to international travel simply on a stressful life. Yes, I have a lot to handle and it’s a fine balancing act managing my part-time job, my degree and my social life to a perfect level. But really I think we are the first generation in a truly open world, where we can get anywhere, see anything and experience every culture under the sun, at the click of a button, the purchase of a ticket.
Many people I met while working in China were surprised at the number of countries I’d travelled to, which came as a surprise. Compared to friends and family I consider myself vastly under-travelled. I’ve yet to even set foot across the pond in the U. S. A and Canada. let alone South America and even within Europe, my checklist of destinations is far from complete. But more eye opening for me, I was also met by astonishment at how little geographical traversing I had done within my own borders. This was something I had not really considered before and as I left Beijing I felt an overwhelming appreciation not just for the rich culture of China but also for the diverse localities within the UK. How much of my own country had I really seen and experienced? To those from a place as vast and varied as China, Britain was really so small in comparison and so to have spent 20 years there and not seen every nook and cranny of it was quite surprising.
I spent a while engaged in a convention with a Chinese colleague over the difference in building style, in architecture from the Highlands of Scotland to the Cornish const. Now for most people this sounds dreary and dull, and I guess I am biased as a student of history who finds anything remotely historical fascinating. However it was not the geological variety of stone within British cities I found interesting. We continued our discussion, yet I was left embarrassed that I could not provide a concrete answer to her question. In China, as well as a wealth of new culture that fascinated me, I discovered that there were parts of the UK’s culture, history, the very structure of my identity that were so different, so unique from China that I also gained a new found interest in my own heritage.
In this respect, travelling enables you with two things. Firstly, you develop an overwhelming fascination with new cultures, understanding customs, experiencing cuisines and absorbing the sights and smells of every new city. For many employers this adaptability to new locations is seen as a tremendous asset to your personal resume. But alongside increased employ ability, through international, cross-cultural conversations, you develop an interest in your own history, culture, and customs. You return to your home filled with an understanding of other people’s fascination with it and imbued with your own sense of love for its peculiarities.

The other day, a friend sent me an email, asking if I’d consider writing about educational apps for children to watch while on road trips. The email said, “
While the intention is well-meaning, I disagree with his idea. There is so much to see on a road trip!
Take physical books along. Choose some novels for an older reader, get cartoon books, or take interactive books such as I Spy, coloring books, puzzle books, etc.

【推荐1】Have you ever noticed what happens to an idea once you express it? Just talking about it or writing it down causes you to make it clear in your own mind. How can you use this to increase your brain power? Start writing.
By putting thoughts into words, you are telling yourself the logic (逻辑) behind what you think, feel, or only partly understand. Often, explaining a thought is the process of understanding. In other words, you increase your brain power by exercising your “explain power.”
Try this experiment. Explain how you’ll increase your brain power, even if you have no idea right now. Just start with anything, and create an explanation. For example, start with “I’ll learn chess,” or “I’ll read an article on the mind every week.” Explain how that will help. You’ll be surprised how often this becomes a workable plan, and if you actually do this, you’ll have a better understanding of your brain from now.
Another benefit of writing is that it helps you remember. Many, if not most, highly productive people are always taking notes. You can try keeping it all in your head, but if you keep a journal of your ideas the next time you’re working on a big project, you’ll probably have more success.
Want to understand a topic? Write a book about it. That’s an extreme example, but if you are learning something new, write a letter to a friend about it, and you will understand it better. Want to invent something? Write an explanation of the problem, why you want to solve it, and why it is worth solving, and you’re half-way there.
Writers don’t always write because they clearly understand something beforehand. Often, they write about something because they want to understand it. You can do the same. Writing will help bring you to an understanding. Give it a try.

【推荐2】There are a couple of ways to forecast the destructive potential of a hurricane so that people in the way can take adequate precautions (预防措施). Satellite images of cloud patterns can be analyzed to estimate peak wind speeds, but the estimates are often way off the mark. Specialized aircraft can fly into a storm to measure the winds directly, but the flights are costly.
Researchers at the Massachusetts Institute of Technology come up with a third way: listening to a storm underwater.
In a paper to be published in Geophysical Research Letters, Nicholas C. Makris and a former graduate student, Joshua D. Wilson, report a strong connection between the intensity (强度) of sound recorded by an undersea microphone in the mid-Atlantic and the wind power of a hurricane that passed over it. They say that such microphones, known as hydrophones, could be a safe and relatively inexpensive means of estimating hurricane force.
Dr. Makris and Dr. Wilson, who are now with Applied Physical Sciences Corporation, worked out the theory of underwater acoustic (声音的) monitoring of storms in a 2005 paper. “To be very frank with you, it’s a mystery what makes storms noisy underwater.” Dr. Makris said. The most popular idea currently is that it has something to do with oscillating air bubbles (气泡振动).
The researchers then went looking for experimental data to back their theory, and found it from a hydrophone placed at a depth of 2,500 feet by the National Atmospheric and Oceanic Administration. It happened that Hurricane Gert passed over the area in September 2009, and a hurricane-hunter plane directly measured the wind speed at the same time. The hydrophone data showed sound intensity rose when the storm’s outside wind “wall” passed over, and again when the inside wall, the most destructive part of the storm near the eye, passed over. “We got a beautiful connection,” Dr. Makris said, “between the hydrophone data and the actual wind speeds as measured by the aircraft.”
Dr. Makris is conducting additional experiments, working with the Mexican Navy off the west coast of Mexico. The eventual goal, he said, would be permanent hydrophones in known hurricane zones or temporary ones that could be easily laid by plane or ship in the path of a coming storm.

【推荐3】Adding just a few plants to a bare front garden can lower stress levels and help people feel happier, research suggests.
Researchers introduced decorative plants such as juniper, azaleas, clematis, lavender, daffodil bulbs and petunias into small bare front yards in economically backward streets in Salford, Greater Manchester.
The study by the Royal Horticultural Society (RHS) and the universities of Sheffield, Westminster and Virginia in the US then measured the stress levels of residents taking part in the experiment and asked them how they felt.
Each residents could receive one tree, one climber and enough smaller plants and bedding plants to fill two containers. They were not required to look after the plants, as the containers were “self-watering” with a 22-litre in-built reservoir (蓄水池) of water, but they were encouraged to take part in gardening their plots (小块地), with help from the RHS advisory team.
The team measured residents’ cortisol (皮质醇) — the key stress response hormone (激素) — before and after the plants were added, and found a higher proportion(比例) of healthy daytime cortisol patterns after planting, suggesting they had a better health state.
The research found only 24 per cent of residents had healthy cortisol patterns before the plants went in, but over the year following the greening of the front gardens, this increased to 53 per cent.
More in-depth interviews showed the garden motivated people to do more gardening and repair and paint other areas of their homes and gardens. They also found gardening is relaxing and that it gave them a sense of pride in their homes, and all of them reported the plants made them feel more cheerful and lifted their spirits when they looked at them.
“The stress reduction data is amazing, in that we found such a significant response with just a relatively small number of plants. We can now further evidence the vital need to include plants in our front gardens and domestic spaces,” said Dr Lauriane Suyin Chalmin-Pui, who conducted the research as part of her PhD.

The area of the Yuyuan and Chenghuangmiao (City God Temple) is crowded at night with tourists trying to get a view and a taste of traditional Shanghai.
Three of Shanghai’s top destinations, the Shanghai Science and Technology Museum, the Shanghai Oriental Pearl Tower and the Shanghai Wildlife Park, have jointly launched a new city pass program to attract tourists both from home and abroad.
Under the Shanghai Pass ticket system, visitors can book online one-, two- and three-day passes covering the three destinations. With different prices for adults and students, they can scan QR codes to enter each of the destinations during the validity of their pass.
The new program will mainly focus on popularizing science as the city receives an increasing number of student visitors.
The three destinations also linked agreements with online travel agency Ctrip to cooperate further on marketing, activity-planning and communications.
Besides the discounted prices, through which you can pay less, the city passes provide more convenience for tourists, especially tourists from other countries, says Xu Ting, the secretary-general of the Shanghai Tourism Association.
Nearly 100 travel destinations have promised that they will take part in the Shanghai Pass program and work with Ctrip.
A total of 105 scenic spots, art galleries, museums and memorials across the city have taken special measures to meet the growing need for nighttime leisure from both Shanghai residents and tourists, according to the municipal culture and tourism bureau.
Parks and leisure spots including the Shanghai Ocean Aquarium and Shanghai Jinjiang Action Park have extended their opening hours, while destinations such as the Shanghai Oriental Pearl Tower, Shanghai Wildlife Park and Shanghai Happy Valley have launched special late shows and night-tour programs.

【推荐2】Happiness is for everyone. You don’t need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.
In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy, too. All these are your happiness. If you notice them, you can see that happiness is always around you.
Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can’t be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge yourself. So you cannot always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转 ) door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.

During this time, all my knowledge of him was limited to occasional meetings about the house,when he would sometimes pass me coldly, and sometimes bow and smile. His changes of manner did not offend me, because I saw that I had nothing to do with the cause of them.
One evening, several days later, I was invited to talk to Mr. Rochester after dinner. He was sitting in his armchair, and looked not quite so severe, and much less gloomy. There was a smile on his lips, and his eyes were bright,probably with wine. As I was looking at him, he suddenly turned, and asked me, “Do you think I am handsome,Miss Eyre? ”
The answer somehow slipped from my tongue before I realized it: “No, sir.” “Ah,you really are unusual! You are a quiet, serious little person, but you can be almost rude.” “Sir,I'm sorry. I should have said that beauty doesn't matter, or something like that,” “No, you shouldn't! I see,you criticize my appearance, and then you stab (刺) me in the back! You have honesty and feeling. There are not many girls like you. But perhaps I go too fast. Perhaps you have awful faults to counterbalance (抵消) your few good points.”
I thought to myself that he might have too. He seemed to read my mind, and said quickly, “Yes,you're right. I have plenty of faults. I went the wrong way when I was twenty-one, and have never found the right path again. I might have been very different. I might have been as good as you, and perhaps wiser. I am not a bad man, take my word for it, but I have done wrong. It wasn't my character, but circumstances which were to blame. Why do I tell you all this? Because you're the sort of person people tell their problems and secrets to, because you're sympathetic and give them hope.”
It seemed he had quite a lot to talk to me. He didn't seem to like to finish the talk quickly, as was the case for the first time.
“Don't be afraid of me, Miss. Eyre,” he continued. “You don't relax or laugh very much, perhaps because of the effect Lowood school has had on you. But in time you will be more natural with me, and laugh, and speak freely. You're like a bird in a cage. When you get out of the cage, you'll fly very high. Good night.”

【推荐1】Tayka Hotel De Sal
Where: Tahua, Bolivia
How much: About $95 a night
Why it’s cool: You’ve stayed at hotels made of brick or wood, but salt? That’s something few can claim. Tayka Hotel de Sal is made totally of salt - including the beds (though you’ll sleep on regular mattresses and blankets). The hotel sits on the Salar de Uyuni, a prehistoric dried-up lake that’s the world’s biggest salt flat. Builders use the salt from the 4,633-square-mile flat to make the bricks, and glue them together with a paste of wet salt that hardens when it dries. When rain starts to dissolve the hotel, the owners just mix up more salt paste to strengthen the bricks.
Green Magic Nature Resort
Where: Vythiri, India
How much: About $240 a night
Why it’s cool: Riding a pulley (滑轮) -operated lift 86 feet to your treetop room is just the start of your adventure. As you look out of your open window - there is no glass! -you watch monkeys and birds in the rain forest canopy. Later you might test your fear of heights by crossing the handmade rope bridge to the main part of the hotel, or just sit on your bamboo bed and read. You don’t even have to come down for breakfast - the hotel will send it up on the pulley-drawn “elevator”.
Dog Bark Park Inn B&B

【推荐2】If, for some reason, you had 2,010 empty plastic bottles, what would you do? You’d probably sell them cheaply, right? But Xia Yu collected 2,010 bottles and built a boat with them. As you read this, Xia is, in fact, on a river somewhere in Anhui, slowly going towards his destination: the Expo Garden in Shanghai. 2,010 plastic bottles were to celebrate Expo (世博会) 2010 Shanghai. On the opening day of the Expo, Xia, together with five friends, went on a 1, 500km journey from Xiangtan to the Expo Garden, in spite of the doubt whether they’ll make it. After all, the boat they are on can hardly be called a boat. It cost only 2,000 yuan to build in a month.
What’s keeping Xia going is a major cause behind the trip. “We are examining water pollution through our journey and trying to promote a low-carbon (低碳) lifestyle. Before we started, no one believed we could sail the boat to the Dongting Lake. But we made it.” But as they expected, the journey has not always been smooth. Of the six from Xiangtan, four gave up. As of the press time (到发稿时), only Xia and his friend Huang Ying were on the boat. Huang suffered from a disease when they reached Jiujiang, Jiangxi province, Xia said, “There are so many things that can stop us from making it to Shanghai, like the weather, health, and sometimes swift river water”.
The boat was produced in a factory according to our design, and perhaps it’s not in a very good condition. But, Xia said, “we are wearing life jackets. Some boats passing by offered help”. What is more of a reward for Xia and Huang is that the Yangtze River turned out much cleaner than they had expected. Although Xia and Huang are uncertain about the journey ahead, they are quite happy with what they have already achieved. After all, it’s not the destination that counts. It’s always the course that matters the most.

【推荐3】Female seals don’t change their spots, according to a new study by University of Alberta biologists. In fact, individual differences in boldness remain consistent over time. The study is among the first to examine boldness in wild marine mammals in the field of animal personality. Animal personality influences many ecological processes, like how individuals interact with other species or respond to changing environmental conditions.
Researchers studied female seals on Sable Island, home to the world’s largest grey seal colony. Over a period from 2008 to 2016, biologist Christi Bubac and a field team led by Fisheries and Oceans Canada measured boldness responses in the female seals when defending their young.
“During the breeding season, we saw that females tend to behave consistently, not only between years, but also within the lactation period of a given year,” explained Bubac, lead author and PhD student in the Department of Biological Sciences studying with wildlife geneticist David Colman. “This provides an example of animal personality, with consistent individual differences observed over time.”
Bubac also examined how reproductive success is related to a seal’s boldness or shyness. Rey seals nurse for 16 to 18 days, so mother seals have a very short window to get baby seals as fat as they can. During this time, baby seals triple in body mass. Body mass is a good predictor of reproductive success because it indicates the puppies’ chances of survival. “On average, we found that bolder females stop feeding those that are two kilograms heavier, compared with the shyest females, improving their chances of surviving the first year of life,” said Bubac.
These results present some very interesting biological questions, explained Coltman, professor of biology. “This research shows that young grey seal moms that are bold tend to stop feeding larger puppies compared with shy moms. However, older grey seals also tend to be bolder. If bolder animals have bigger pups and live longer, why does variation in boldness remain? Why be shy?”
