The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid—we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

    However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting. ''

    But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.

    Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!

    Elephants are able to know the difference between a man and a woman, and can tell an adult (成年人) from a child—all from the sound of a human voice. This is according to a study in which researchers played voice recordings to wild African elephants.

    The animals showed more fear when they heard the voices of adult Masai men. Usually Masai people hunt elephants, and this suggests that animals have grown to listen for and avoid them.

    Prof. Karen McComb and Dr Graeme Shannon from the University of Sussex led the study. They explained that in former research they had used similar experiments to show that elephants could tell—from the sound of a lion—whether the animal was a female (雌性) or a more dangerous male (雄性).

    Prof  McComb wanted to find out if the animals used their very sharp sense of hearing to recognize danger from humans.

    The scientists recorded Masai men, women and children saying, in their own language, "Look, look over there, a group of elephants are coming." They also recorded Kamba men saying this phrase.

    Masai people often come across elephants, which can result in violent (暴力的) hunting. Kamba people, however, mainly feed on agriculture, which does not generally bring them into violent touch with the animals.

    When the team played recordings of these different voices through a hidden speaker, they found that elephant family groups showed more fear in response to the voice of a Masai man, than to a Kamba man's voice. And the adult male Masai voices caused far more violent response than the voices of women or boys.

Last year, the Bureau of Labor Statistics reported that 55 million people in the U. S. are "gig workers" which is more than 35 percent of the U. S. workforce. That number is projected to jump to 43 percent by 2020.

People are drawn to gig work（零工）because it brings in a little extra income without a major time commitment. And recent technologies like Skype, Slack, and Dropbox have made the gig life a reality, giving you maximum freedom, an ideal work-life balance, and the chance to pursue your passions.

If you're thinking of joining the gig economy, it's never been easier. One of the great things about the gig economy is that you don't have a boss breathing down your neck. As a freelancer, you no longer have to cater to a company culture or work schedule that might cause physical or emotional stress. Instead, you get to choose the type of work you do and who you work with. But this degree of freedom requires a corresponding amount of discipline. With no boss to make sure you're on task, it's all on you.

A lot of gig workers start their careers by hopping on a project because the employer is desperate and in need of help. On the employer's end, it's tough to take on people for higher management positions when the pool of talent is full of gig workers who haven't been given an opportunity to improve their skills. Businesses have to evolve to learn how to account for an influx (涌入) of temporary workers. It is harder for gig workers to become skilled and get promoted.

The workforce is becoming more advanced and educated by the day. You have to keep learning and keep up with industry trends to maintain a competitive edge. This is true even for people in traditional office settings, but it's critical if you're your own boss.

The last few days before Christmas passed quickly and it was soon Christmas Eve. That night when everyone went to bed, Bunny couldn't sleep. He still couldn't think of what he wanted his Christmas gift to be. He wondered how Father Christmas would know what to bring him if he didn't know himself.

As he was sitting up in bed, Bunny heard a big noise on the roof (屋顶) and a sound downstairs. It was Father Christmas, he realized. Bunny jumped out of bed and raced down the hall to the stairs hoping to have a look at the old man with his own eyes.

By the time Bunny reached the bottom of the stairs, though, everything was again silent. Beautiful gifts were piled (堆积) under the Christmas tree, but Father Christmas was gone. He looked for him for a few minutes, but it was already too late. Bunny turned to climb back upstairs when he heard a cry.

"Hello," said Bunny. "Is anybody there? "

He was answered by another cry. Bunny looked around the big pile of gifts to see what was making the noise. Right under the tree was a funny looking brown animal with big feet and sad eyes. Bunny might have mistaken it for a dog, if it hadn't been for the antlers (鹿角) on its head.

"Are you a reindeer (驯鹿)?" asked Bunny.

"Yes," replied the animal. "My name is Ralph."

"And you were pulling Father Christmas's sled (雪橇)?"

"I was until I got airsick (晕机), " replied Ralph. "I'm afraid I wasn't cut out for the job. Now I'm stuck here and I don't know how to get back to the North Pole."

"Well, if you like, yon can stay with us as a friend," said Bunny. As he made the offer, Bunny suddenly realized the gift he wanted from Father Christmas was a new friend!
