Who could have imagined that a treadmill(跑步机)on wheels would one day become a thing?!? Lopifit is an unusual means of transportation that allows you to power an electric bicycle by walking on a treadmill.

Lopifit founder Bruin Bergmeester says it all started when he asked himself the question “How can I use a treadmill outdoors?” He finally came up with a new design, adding an electric motor, and the Lopifit was born. It’s similar to an electric bicycle in that the motor only works when the rider puts power in as well. The Lopifit senses when you walk on the treadmill and uses the motor to turn a drive chain at the back of the treadmill, helping you reach a top speed of 17 miles per hour.

To use the Lopifit, simply turn on the battery(电池)and use your foot to slide the treadmill backwards and start the motor. Then get on and enjoy the ride! If you need speed, just walk on the treadmill, and if you want to coast(惯性滑行), all you have to do is stay still and admire the view. To stop, you have two hand breaks.

The Lopifit first hit the streets in 2014 and, unsurprisingly, became a hit overnight. That was actually quite challenging for the company, because it started getting calls for orders, but it was nowhere near ready for mass production. The unique treadmill bicycle could be bought this year, and Lopifit is struggling to keep up with demand, although the price is up to $2,115.

Some people consider this means of transportation stupid and unnecessary, although there is a very loyal fan-base of so-called Lopifitters. They simply believe that if you’re going to walk, you might as well do it the old-fashioned way.

But the Lopifit does have the special advantage of helping you “walk” really fast without much effort, or walking at cycling speed, if you will.

The Oxford Dictionary has announced its word of the year. It's spelled... Actually, it isn't spelled at all, because it contains no letters, just a “face with tears of joy” emoji.

“The fact that English alone is proving not enough to meet the needs of 21st-century digital communication is a huge change,” says Caspar Grathwohl, president of Oxford Dictionaries. When one of his dictionary colleagues suggested using an emoji instead of the word “emoji”, “lightbulbs went off”. Until recently, Grathwohl, who is 44, avoided using emojis altogether because he worried that he would look as if he “was trying to get in on teen culture”. “I felt inauthentic. But I think there was a tipping point this year. It's now moved into the mainstream.”

Some 76% of the UK adult population owns a smart phone, and of those, between 80% and 90% use emojis. Worldwide, six billion are sent daily. The “face with tears of joy” is the most used, representing 20% of all UK and 17% of all US emoji use. It has overtaken the standard smiley-face emoji in popularity, which may mean that emoji users are moving towards exaggeration or irony or fun, or that all this emoji use has brought everyone to a higher emotional plane. Even if you don't send emojis yourself, you will probably receive them.

How far do emojis function as a language? “There's a lot of prejudice against emojis,” Vyvyan Evans, a professor in linguistics at Bangor University, says. “A lot of people think they are a backward step, but this misunderstands the nature of human communication.” The picture is more complicated, with emojis offering both greater freedom and limitations than verbal language. “Emoji isn't a language as such. They don't develop in the way that the natural language does. But they are working according to the same principles of communication as the spoken language. What is the value of an emoji? I think I can prove this with an ordinary sentence.” There is a pause. “I love you,” he says. “Crikey(哎呀), I love you.” He says it again. The first time I think he means it; the second time we both know he doesn't. “The meaning is coming from extra-language factors,” he says. “Emojis are performing the same function in digital speech.”

Like any sort-of language, emoji is evolving. “I do think they are subtle(微妙) and rich,” Grathwohl says. “They can mean different things to different people. The fact that we are using emoji in combination to express more complex ideas and experiences is one of the most fun and playful parts of the whole words. Will emoji finally come to look something more like traditional language that we understand?” he asks. “That would be interesting.”

1.The sentence “lightbulbs went off” (Para. 2) means that     .

A. the president became embarrassed and annoyed

B. the president suddenly realized he was outdated

C. the suggestion was immediately adopted

D. the suggestion started a heated discussion

2.The “face with tears of joy” is more popular than smiley-face emoji, which means that     .

A. emoji is changing constantly

B. smiley-face emoji is too traditional

C. adults have more sorrow than joy in their daily life

D. people like to express their emotions in a richer way

3.Vyvyan Evans uses the sentence “I love you” as an example (Para. 4) to prove that     .

A. emoji can express the real meaning behind words

B. emoji is different from the natural language

C. people feel free to use emoji in communication

D. emoji will limit people in expressing their feelings

4.Which of the following statements might Grathwohl agree with?

A. Emoji is too childish for adults.

B. People have the same explanation for an emoji.

C. Using emoji can add fun to communication.

D. Emoji won't develop into a language.

You might make a disgusted face when you notice that the person waiting in their car at the red light next to you is picking their nose,but admit it,you do it too.And while it might be the natural option when there isn't a box of tissues around,it can be bad for you.The main reasons people feel the need to pick their nose is to clear it of dried liquid,stop an itch(痒),or just because it feels good.Boogers(鼻屎)form when dried liquid and cilia,the tiny hairs that line the nostrils(鼻孔),trap the dust,dirt,and other things.When boogers build up in your nose,it can be uncomfortable,and sometimes just blowing into a tissue doesn't do the trick.

Otolaryngologist Erich P.Voigt,MD,told Business Insider that picking your nose can cause injuries and bleeding within your nostrils.That's not terribly damaging,but when the bacteria from your hands get into your body,it can cause a cold and flu.So doctors strongly suggest not picking the nose.

If dry winter air is causing the dirty liquid to harden in your nostrils,making you want to pick,consider damping the air at home,or taking a steam shower to soften things up in there.

Children,who are most famous for having a finger up their nose,sometimes don't realize how much injury they're causing,and sometimes it.can lead to nose bleeds.

So,next time you go to pick your nose,think about how many bacteria are on your hands and in your boogers, and maybe reach for a tissue instead.Even if you 're alone,and not waiting for the light to turn green,please,use a tissue.
